Activation of the aerodynamic valve
Motion of work:
The number of cylinders can be adjusted to the requirements of the rotational rectangles required for load (valves), to drive loads (valves) to rotate the main axle, to compress the air exhaust to the casks, to change the direction of the main axial aerodynamics。
The two five electromagnetic valves are usually used in conjunction with the dual-action gas-enabled implementing agency, and the two are controlled at two locations: the switch-off, the five are operated through five corridors, one of which is connected to the gas source, the two are connected to the exit and exit vents of the external gas chamber of the dual-acting gas tank, and the two are connected to the inbound and outbound vents of the inner gas chamber, and the specific working principles are based on the working principles of the dual-acting gas-enabled implementing agency。
Extension:
Daily maintenance attention for aerodynamic valves:
1. Valves shall be stored in a dry and ventilated room and shall be blocked at both ends of the route。
2. Valves for long-term storage shall be inspected periodically, the contamination removed and the stainproof oil painted on the processing surface。
3. Once installed, periodic inspections shall be carried out to check the main items: (1) seal face wear and tear. (ii) graving wear and tear of valve poles and valve nut. (3) the fillings are obsolete and, if damaged, replaced in a timely manner. (4) a seal performance test shall be performed after the valve has been overhauled。
Maintenance of aerodynamic valve:
1. The purpose of the maintenance is to extend the lifetime of the valve and to ensure reliability of release。
2. The screws of valves, which often friction with the screws of valves, are lubricated with a little bit of dry oil, molybdenum disulfide or graphite。
3. Infrequently closed valves are also periodically rotated and lubricant is added to the spiral of the valve to prevent bites。
Outdoor valves shall be protected against rain, snow and dust stains。
5 if the valve is mechanically still, lubricated oil is added to the gearbox on time。
6. Always keep the valve clean。
7. The integrity of other components of the valve shall be regularly checked and maintained. If the fixed nuts of the wheel fall off, they must be fully fitted and not fit for use, otherwise they will grind the upper quadrilateral of the valves, gradually losing the reliability of their alignment or even being unable to start。
8. Do not rely on valves to support other heavy matter and do not stand on valves。
9. Valve poles, especially screwdrivers, are often wiped and lubricated with new lubricants, which are already dirty with dust because of the presence of hard impurities, the ease of grinding the threads and the surface of valves, and the influence of the active life gas mono-seat control valves。

What does the aerodynamic valve work for
Aerodynamic valves:
Multiple combinations of aerodynamic piston motion electromagnetic valves and aerodynamic valves in compressed air boosters 341f. Com/'target=`blank'> ball valves are connected, transmitted to the characteristics of beams and inner curve orbits, drive the main axis of the core for rotation, compress the air exhaust to the cylinders, change the direction of the main axis by changing the direction of the gas, and adjust the number of cylinders to the requirements of the rotational rectangles required by the load (valves) to drive the load (valves)。
The two five electromagnetic valves are usually used in conjunction with the dual-action gas-enabled implementing agency, and the two are controlled at two locations: the switch-off, the five are operated through five corridors, one of which is connected to the gas source, the two are connected to the exit and exit vents of the external gas chamber of the dual-acting gas tank, and the two are connected to the inbound and outbound vents of the inner gas chamber, and the specific working principles are based on the working principles of the dual-acting gas-enabled implementing agency。
Extension:
In accordance with the processing requirements, some parts of the parts need to be polished and the surface must not contain, for example, processed hair pricks; all parts need to be defamined; acidized passivation after defamination is completed and the washing agent does not contain phosphorus。
The acid wash is rinsed with pure water and cannot be left with pharmaceutical residues, and the carbon steel parts are omitted from this step; parts and components are emptied with unwielded cloths, spare parts such as wired hair or dry with clean nitrogen gas; parts and components are wiped with non-width or refined filters to analyse pure alcohol until they are not dirty。
What does the aerodynamic valve work for
I saw it
But i can't find it now
The ultra-high-pressure gas pressure reduction valve is an important component of the aerobic brake system。
The control valves are easily leaked because of the small viscosity of the gas and the high pressure of the system to work, and the input pressure of the valves is 11-13ma, with the highest output。
The pressure is 7mpa, so the sealing and durability of valves are prominent issues. The ultra-high-pressure aerodynamic pressure reduction valves described here break traditional structures [1] and optimize important zero and components。
Designed to keep valves free of leakage at high pressure and other performances meet the requirements for use。
2. Rationale
The operation of the ultra-high-pressure aerodynamic pressure reduction valve is shown in figure 1. When the head of the pressure does not function externally, the gas from the gas source enters the lower chamber of the valve by entering the water-drive valve, which enters at the pressure and at the reposition spring。
The action is tight with the entry valve door, and the valve output is non-gaseous. When the pressure is subject to external force f, the pressure moves down the head, compressing double-position spring 1 by balancing the spring, pressing the exhaust valve with the exhaust valve。
Door contact separates the transport and export from the atmosphere, and the pressure continues to move down, tops open the gas valve and compresses the air into the executive element cylinder behind the valve by the channel controlled by the entry valve. With tank pressure。
The increase reduces the opening of the entry valve until the entry valve is closed when the flow-export pressure p2 is balanced with the effect of the pressure. When external force is removed, the entry valve is in the pressure and re-entry spring 2。
, move it up. At the same time, how the electromagnetic and aerobic valves are connected, repositioning the head and exhaust valves under the combined spring 1 force and exhaust pressure, opening the vent and passing the gas from the original output。
The silencer discharges into the atmosphere。
The principles of aerodynamic magnetic valves
Aerodynamic magnetic valves have closed cavities, open holes at different locations, each hole of the aerodynamic magnetic valve leads to different pipelines, with valves in the middle, two electro-magnetics on both sides, and which side is attracted to the magnetic wire valves
Aerodynamic magnetic valves contain or leak different vents of discharge by controlling the movement of valves, which are often open, and hydraulic fluids enter different discharge tubes, and then push the oil piston through pressure from the oil of the aerodynamic magnetic valves, thus controlling the entire mechanical movement of the electromagnetic valves by controlling the current of the electromagnetic magnets of the aerodynamic magnetic valves. What we're talking about is the location of the aerodynamic magnetic valves (e. G. Magnetic valves on or off), actually the location of the core of the aerodynamic magnetic valves。
The valve core is located in position a when it is offline, and in position b when it is offline. When the core of the aerodynamic magnetic valve is in different positions, the interfaces on the valve are either connected or closed. For example, two electromagnetic valves are the cores of the electromagnetic valves with two different working positions (on or off) and, for aerodynamic magnetic valves, the electrical state of the electromagnetic valves and the power loss state; and for valves under their control, the opening and closing of the valves. Two or three electro-magnetic valves are two or three portals on the valves of the aerodynamic electromagnetic valves. The two two electromagnetic valves, with two corridors in and out, are the most common aerodynamic magnetic valves; the two three electromagnetic valves, with three channels in and out, of which the two exit channels are open and closed, respectively. Similarly, three, four and five are also the number of fluid channels on the valve. In the design process, air road maps are often required. However, a variety of aerodynamic magnetic valve symbols used in air road maps often make us uncomfortable, as people of self-control origin often do not systematically study the standards of aerodynamic symbols for mechanical specialization. Here, a brief introduction is given to the aerodynamic magnetic valve symbols commonly used in the air road map to facilitate a more intuitive understanding of the aerodynamic electromagnetic valves by self-control designers。
What does the aerodynamic valve work for
The work of the aerodynamic valves is based on the fact that the aerodynamic control valves consist of the implementing and regulating agencies. The implementing agency is the thrust component of the control valve, which generates the corresponding thrust by the size of the control signal pressure and facilitates the action of the regulator. The valve is the regulating part of the aerodynamic control valve, which is in direct contact with the regulating medium and regulates the flow of the fluid。
General requirements:
Aerodynamic valve specifications and types shall conform to the requirements of the piping design document。
2. The model of the aerodynamic valve shall indicate the national symbol requirements on which it is based. In the case of an enterprise standard, the relevant description of the model should be indicated。
3. Aerodynamic valve working pressure requires that, without prejudice to price, the working pressure of a piping tube should be greater than the actual piping pressure; that any side of the aerodynamic valve being closed should bear 1. 1 times the valve value without leakage; and that, in the opening condition of the valve, the valve should bear the requirement of double valve working pressure。
4. The criteria for the manufacture of a gas valve shall indicate the national symbol on which it is based and, in the case of an enterprise standard, the procurement contract shall be accompanied by an enterprise document. Aerodynamic valves are standard country-separated, with three specifications for aesthetic and dailies。
5. The complete description of the aerodynamic valves contains their specification dimensions, materials, means of connection, and the manner of action (in which the action is divided into 1: double action, 2: single action)。
Extension
Both inside and outside the valves (including the gear transfer box) shall be deregulated first with the aim of electrostatic powdered with no toxic epoxy resin of more than 0. 3 mm thick. Large valve electrostatic application should also be coated and sprayed with similar non-toxic epoxy paints in cases of difficulty。
The inside of the valve, as well as the various parts of the valve plate, require full protection from erosion in water and from electrochemical corrosion between the two metals on the one hand; and surface smoothness reduces water resistance on the other。
Health requirements for epoxy resins or paints in the valve that are resistant to corruption should be reported by the appropriate authority. Chemical physics should meet the requirements。
