Angular pulse valve presentation:
The electromagnetic pulse valve (also known as the diaphragm valve) is the compressed air "switches" of the pulsation bag ash blowing system. Controlled by the pulsating blowout controller output signal, the filters are drained (rooms) to clear the dust so that the resistance of the scrubber remains within the given range to ensure the treatment capacity of the scrubber and the efficiency of dust collection. The dmf-z electromagnetic pulse valve is a straight-angled valve with an angle of 90° between imports and exports and is suitable for the installation of a gas package and a dedustor blowout tube. The air flow is smooth and provides the required ash gas pulse。
The emp works:
The film divides the electromagnetic pulse valves into the front and the second two chambers, and when connected to the compressed air, the compressed air enters the rear chamber through the throttle, at which time the latter pressure puts the film components at the point of export of the valve and the electromagnetic pulse valve is “closed”。
The pulse blower's telecommunication number allows the electromagnetic pulse valve to move back behind the title iron, opening the vent in the rear chamber, rapidly losing pressure in the back chamber, moving back on the film components, blowing out the compressed air through the valve to export and “opening” the electromagnetic pulse valve。
The pulse blower telecommunications number has disappeared, the electromagnetic pulse valve has been re-organised, the rear vent has been closed, the post-air chamber pressure has increased so that the film components are in a state of “closure”。

The work of the electromagnetic valve
The electromagnetic valve is an automated base element used to control the direction of the fluid and is an implementer; it is usually used for mechanical control and above the industrial valve to control the direction of the medium to achieve control of the valve switch. The electromagnetic valves have closed cavities, opening holes in different locations, each of which leads to different pipelines, with valves in the middle, with two electro-magnetics on both sides, and which side of the magnet wire-ring valves will be attracted to, either by controlling the movement of the valves to contain or leak different vents of discharge, while the vents are often open, the hydraulic fluids enter different discharges, and then push the pistons of the tanks through pressure from the oil, which then drive the pistons, which drive the pistons, which drive the pistons, which drive the pistons, which drive the machinery. This controls mechanical motion by controlling the current of electromagnetics. Only the electromagnetic valves are performed with electromagnetic force on the steel cores sealed in the electro-regulating valves in a magnetic tube, and there are no motion seals and leaks are easily blocked. Electric valve rectangles are not easily controlled, causing leakages or even pulling off the head of the valve pole; the structural shape of the electromagnetic valve is easily controlled by internal leakage until it is reduced to zero. Therefore, electromagnetic valves are used in a particularly safe manner, especially for corrosive, toxic or high temperature media. The electromagnetic valves themselves are simple in structure and low in price, and are easier to install and maintain than other types of implementers such as the regulating valves. More significantly, self-control systems are made up of much simpler and lower prices. Since the electromagnetic valve is a switch signal control, it is easy to connect to a manual control computer. The advantages of electromagnetic valves are even more evident in an era of widespread computer penetration and sharp price declines。
Form types of electromagnetic valves
1. Directly mobile electromagnetic valves:
Principle: when electrically activated, the electromagnetic circle produces electromagnetic power to lift the closure from the valve and open the valve; when electricity is cut, the electromagnetic power disappears, the spring presses the closure on the valve and the valve closes。
Characteristics: normal working at vacuum, negative pressure, zero pressure, but generally not exceeding 25 mm。
2. Distribution of direct motion electromagnetic valves:
Rationale: it is a combination of direct and lead, and when the entrance and the exit are free of pressure, the electromagnetic force lifts the lead valve and the main valve directly upward and opens the valve. When the opening pressure differentials between the entrance and the exit, the electromagnetic power leads the small valve, the lower cavity pressure of the main valve rises and the upper cavity pressure drops, thus pushing the main valve upwards using the pressure difference; when the power is cut, the lead valves use spring power or medium pressure to drive the closure, move downward and close the valve。
Characteristics: it can also be actionable at zero pressure differentials or vacuums, high pressure, but with greater power, it requires horizontal installation。
3. Lead electromagnetic valves:
The principle is that when electricity is powered, the electromagnetic force opens the lead point, the upper chamber pressure is rapidly reduced, the upper chamber pressure is formed around the shutter, the fluid pressure drives the shutter up, the valve opens; when the power is cut, the spring is turned off, the entry pressure is created by the perforated rapid cavity chamber around the shutter, and the fluid pressure drives the shutter down, closing the valve。
Characteristics: the upper limit of the fluid pressure range is high and can be installed at will (to be customised) but must meet the fluid pressure differential. Electromagnetic valves are divided into six subcategories, with differences in structure and material from the valve and principles: direct motion film structure, step-by-step heavy film structure, lead membrane structure, direct piston structure, step-by-step piston structure, lead piston structure。
Main features of electromagnetic valves
I: applicability
The fluids in the tube shall be consistent with the medium selected for the medium selected for the emp series。
The temperature of the fluid shall be smaller than the rated temperature of the selected electromagnetic valve。
Emps allow liquid viscosity to be generally below 20cst and greater than 20cst should be specified。
The working pressure differentials, which are less than 0. 04 mpa, are selected in a direct and step-by-step motion pattern, such as zs, 2w, zqdf, zcm series; a lead (pressure-by-voltage) electromagnetic valve may be selected if the working pressure is greater than 0. 04 mpa; the working pressure differentials shall be less than the rated pressure of the electromagnetic valves; the general electromagnetic valves are single-way jobs, so care is taken whether there is any inverse pressure differentials, if any。
Filters should be installed in front of the electromagnetic valve when the fluid is less clean, and general electromagnetic valves require a better level of cleaning of the medium。
Pay attention to flow apertures and take-over calibres; electromagnetic valves are generally controlled only by two switches; conditions permit the installation of bypass tubes to facilitate maintenance; and when a water hammer phenomenon occurs, the timing of the opening of the electromagnetic valve is customised。
Pay attention to the effect of ambient temperature on electromagnetic valves
Power currents and power consumption should be selected according to output capacity, with power voltage generally allowed to be around ±10%, and care must be taken that va values are higher when communication starts。
Reliability
Electromagnetic valves are divided into two types of constant shut-down and open; they are generally selected to be closed, open and shut down; however, they are selected to be open at short intervals when they are off at a very long time。
The life-cycle test, which is generally a model pilot project, is not exactly the standard for electromagnetic valves in our country and is therefore carefully chosen for the use of electromagnetic valves。
When action time is short and relatively high, it usually selects a direct motion pattern and a fast series with a large calibre。
Iii. Security
General electromagnetic valves are waterproof and, when conditions do not permit, choose a waterproof type, which can be arranged by the plant。
The nominal pressure of an electromagnetic valve must exceed the pressure in the tube, otherwise the useful life may be reduced or other accidents may occur。
For corrosive liquids, a total stainless steel type should be chosen, and a strong corrosive fluid should be chosen for the plastic king (slf) electromagnetic valve。
The explosive environment must select appropriate blast-proof products。
