Devices that drive the core of the valve in relative motion within the valve. 3 the working principles of the hydraulic valve: the working principles of the hydraulic valve: the use of the core of the valve for relative movement in the valve
2. The use of valve cores for relative movement in the valves to control the passage of the valves and the size of the valves, to achieve pressure, the penetration of the valves and the size of the valves and to achieve control of pressure, flow and direction. Control of traffic and direction. 1. The sorting of slide valves according to the structure form the slide valves are sealed in gap, the cores and valves are sealed in gap, and the cores and valves are sealed for a certain length, so that the movement of the slide valves is within a certain sealed length and therefore there is a dead zone. A dead zone. The cone cone cone cone cone is typically a cone cone cone cone angle of 12,20, with a line seal when the valve closes, with a good seal, with a wire seal when the valve closes, with a good seal and a good motion. And he's smart. The ball valve has the same performance as the cone valve. The performance is the same as the cone valve. It can only flow in one direction, it can only flow in one direction, it can only move in one direction, it can be cut off

Speed. Classification: throttle valves, throttle valves, temperature compensation rate classification: throttle valves, throttles, temperature compensation for velocity valves, stagger valves, stucular flow valves, several throttle bands angular shape, etc. By cutting-edge equations, when the pressure is short, when the pressure is low, when the opening is fixed, changing the opening area is the fluid barrier
8. Accumulation, i. E. A change in the flow of fluids. Change the flow. A new component developed in the early 1970s and 1970s by plug-in and superstition valves is a new application for old cone valves. A new element developed in the early years was the new application of the ancient cone valve. A multifunctional composite valve consisting of a panel, a lead valve. For each plug-in valve, a multifunctional composite valve consisting of a panel, a lead valve. Since each of the basic components of the plug-in valves has and only has two oil mouths, it is referred to as a two-entry valve. The basic components have and only have two oil vents and are therefore referred to as two plug-in valves. N. Characteristics: n valve cores are cone valves, are sealable and actionable; n valves are cone valves, are sealed and actuated; n flow capacity is high, anti-pollution; n valves are fluid and anti-pollution; n valves are multi-utility, make it easier to form various types of systems and have a tight structure. It is multi-purpose, easy to form systems of various kinds and has a tight structure. Not really
9. The advantages are more pronounced in the case of large-flow and non-mineral oil media. Advantages are particularly pronounced in the case of large-flow and non-mineral oil media. Distinction by use: direction valve components, pressure valve components and flow valve components. Distinction by use: direction valve components, pressure valve components and flow valve components. The application of plug-in valves makes it possible to form a one-way valve by using the valve to communicate directly the control of the direction valve components through the passages on the valves and panels with the passages on the oil mouths and panels. Direct communication, which may consist of a one-way valve. A two-bit three-way electromagnetic slide valve is controlled by a two-bit, three-bit electromagnetic slide valve, and two-bit divalves by a two-bit three-bit electromagnetic slide valve control direction valve control component. The two valves are formed. It's made of two direction valve components combined with two direction valve components, forming an external pressure
10. A pressure oil mouth, a working oil mouth, a working oil mouth and a return. Three plugs and a refuelling mouth. The number of working positions of the three plug-in valves is determined by the number of working positions of the pre-replacement valves. Set the number. The four-barrel four-barrel valve is a hydraulic control valve that controls flow and pressure in proportion to the flow and pressure on the basis of the flow and output signal and output signal feedback. Depending on how the signal is entered, the control valve is divided. Depending on the manner in which the signal is entered, the electron-serving valves and machine-serving valves are split. Electronic servo valves and machine servo valves. The electron server valve converts the small power telecommunications code to the high power hydraulic output of the small power telecommunications code to the high power
11, achieves the displacement of the execution element, the hydraulic output of the rate and the control of the movement, velocity, acceleration and force of the execution element. Control of speed, acceleration and force. Vii. Service valve vii. Composition of the service valve: composition: proportional electromagnetic replacement of the regulated screw in the speed valve. The proportional magnet replaces the regulator in the speed valve. Motion: when entering a current working method: when entering a current i i i has a corresponding movement to get a corresponding movement to transform the throttle valve to transform the throttle valve to modify the flow rate.

The skin bag is used as a fuel-resistant rubber and as an inflatable valve. The pelvis is fed by oil-resistant rubber and suppressed with inflating valves, containing inert gases. Together, they contain inert gases. Raise the valve with a spring
13, a recouping fungular valve, which lifts the valve, which is a fungular valve with a spring repo, which allows the fluid to enter the energy unit through the oil wells and prevents the fluids from entering the reservoirs through the oil wells and preventing the skins from being squeezed through the mouths. The inflatable valves are squeezed out only through the oil vent. The inflatable valves are inflated only for the skin before the energy unit works, before the energy unit works for the skin when inflated, and remain closed while the energy unit works. Always close. This structure makes gas, liquid seals reliable, and because it makes gas, liquid seals reliable, and it overcomes the slow response weakness of the piston-capacitors due to the low inertia of the leather-capacitors and therefore the slow weakness of the piston-capacitors, the application of which is not widespread, has the disadvantage of being less process-oriented and often less process-oriented.
