Problems solved by technology

A variety of structures and forms of high-speed switching valves have been developed. However, some single-stage valves with fast switching speeds currently developed have a small flow rate and cannot meet the actual needs of the project. Although the flow rate of the secondary valve is large, the switching speed is relatively low. slow

Embodiment Construction

[0016] like Figure 1 to Figure 3 As shown, an embodiment of the present invention includes: motor fixing bracket 1, motor stator 2, motor mover 3, valve body 4, disc spring 5, gland 6, dynamic seal 1 7, valve core 8, dynamic seal 2 9 , Cone spool 10, compensation sealing piston 11, end face seal 12, inner hex nut 13, etc.

[0017] figure 1 It is a structural schematic diagram of the present invention, figure 2 It is a top view of the structure of the present invention. Among them, the stator 2 of the voice coil motor is kept fixed relative to the on-off valve, and the mover of the motor 3 is directly connected and fixed with the spool 8 of the on-off valve. ; When the voice coil motor passes the reverse current, the motor mover 3 drives the switch valve spool 8 to move upward against the dynamic friction force and the spring force, and the valve port opens; when the voice coil motor passes the forward current, the motor mover 3 drives the switch The valve core 8 moves do...

Abstract

The invention relates to a voice-coil-motor-driven high-speed switch valve. A voice coil motor is utilized to directly convert electric energy into rectilinear motion mechanical energy so as to drive the switch valve core to reciprocate without any intermediate switching mechanism. The voice-coil-motor-driven high-speed switch valve has the advantages of simple structure, no contact, no abrasion, low noise, high speed, high precision and the like. The valve core adopts a split balance-type cone valve structure, and thus, can be subjected to balanced stress in the high-speed switch valve opening/closing process, thereby enhancing the sealing reliability of the valve port, avoiding the leakage of the system, enhancing the pressure/flow control precision, avoiding the energy dissipation and having high pollution resistance. The high-speed switch valve has the characteristics of high response speed, high flow rate, small size, light weight and simple structure, is suitable for gas media and also suitable for system pipelines and the like using oil-base, water-base or any other working medium, is used for controlling the high-frequency opening/closing of the fluid medium, and has very important engineering application value.

Description

technical field [0001] The invention relates to a high-speed on-off valve driven by a voice coil motor, which is mainly suitable for gas medium, and also suitable for system pipelines with oil-based, water-based, etc. as the working medium, and is used to control the high-frequency on-off of the fluid medium. Background technique [0002] Due to the long switching time and low commutation frequency, the traditional on-off valve cannot meet the requirements of high-precision electro-hydraulic control system, while the electro-hydraulic servo valve can obtain high working accuracy, but its anti-pollution ability is poor, and the processing of electro-hydraulic servo valve It's demanding, so it's expensive. However, the high-speed on-off valve always works in the fully open or fully closed state, so the pressure loss is small and the energy consumption is low. It is not sensitive to pollution, more reliable than servo valves, simple in structure, low in price, and has better w...
