Problems solved by technology

But the typical disadvantage of this type of valve is that when the working pressure is low to a certain value, the valve cannot be opened.
The disadvantage that the valve cannot be opened in the entire working pressure range limits the application fields of this type of valve
This limits the application of this type of valve in the delivery process of high-purity / high-pressure / large-flow hydrogen
[0005] But no matter what kind of valve is used, there is a common problem in practical application, that is, the coordination between the actuator and the valve, that is, the split design of the actuator and the valve makes its manufacturing accuracy and process quality not easy to be controlled. Control, which in turn affects the stability of the device

Abstract

The invention discloses a large-diameter vacuum high-pressure control valve which comprises a valve seat of a hexahedron structure. The piston and the valve element assembly are arranged in the valve seat; wherein the lower portion of each face of the valve seat is provided with a matched cavity, and all the cavities are communicated through matched hole channels in space; the chambers are configured to comprise a piston assembly installation chamber, a valve element assembly installation chamber, a low-pressure exhaust chamber, a high-pressure air inlet chamber, a pressure sensor assembly installation chamber and an electromagnetic valve element assembly installation chamber. According to the large-diameter vacuum high-pressure control valve, through the structural design of the valve seat, all executing mechanisms for achieving the functions of the automatic control valve are integrated on the six-way valve seat, integrated machining and manufacturing can be completed, and the machining and manufacturing precision is easy to guarantee; the technology is mature, the difficulty is small, the cost is low, the quality in the machining process is easy to control, and better adaptability is achieved.

Description

technical field [0001] The present invention relates to the field of mechanical design and manufacture. More specifically, the present invention relates to a large-diameter vacuum high-pressure control valve whose working pressure covers vacuum and high pressure, and is mainly used for automatic control of large-flow high-pressure fluid conveying process. Background technique [0002] In the field of hydrogen energy applications, the safe delivery of large amounts of high-pressure hydrogen will be involved, and the hydrogen pressure may be as high as 10MPa. There are two main types of automatic control valves used for large flow and high pressure gas delivery, electric shut-off valve and pilot valve. [0003] Valves such as electric globe valves mainly use a geared motor to drive the valve core to move up and down to close or open the valve, and seal the valve stem with a packing seal to seal the valve body and the outside air medium. The advantage of this type of valve is...
