High-pressure regulation valve and pressure detection device

Abstract

The invention discloses a high-pressure regulation valve and a pressure detection device. The high-pressure regulation valve comprises a first joint, a transverse first valve cavity, a second joint, a transverse second valve cavity, a centre and a power source, wherein the first and second joints are communicated with the first and second valve cavities respectively; the first valve cavity and the second valve cavity are in butt joint; a conical cavity is arranged at the butt joint of the first valve cavity; the cavity wall of the conical cavity is a conical surface; the conical surface is matched with a sphere; the power source drives the centre to move transversely and linearly through a thread pair; and the centre drives the sphere to move transversely and linearly. The pressure regulation valve converts circular motion into linear motion by use of the lead screw principle; the centre pushes open the sphere to control blockage; the fluid flow is controlled by use of the size of an opening / closing gap of the sphere so as to control the pressure range of the system; and thus, the pressure regulation valve not only realizes a complete blockage function, but also can control the pressure of the system and loop.

Description

technical field [0001] The present application relates to a high-pressure pressure regulating valve. Background technique [0002] For hydraulic and pneumatic equipment or fluid transmission occasions in industrial and agricultural production, it is necessary to adjust fluid pressure and on-off control. Commonly used fluid pressure control valves include relief valves, pressure reducing valves, sequence valves and pressure relays. The function of the pressure control valve is to keep the pressure of the controlled fluid circuit or system stable, and realize the functions of stabilizing, regulating and limiting the pressure. Commonly used globe valves include diaphragm valves, ball valves, plug valves, disc valves, plunger valves, ball plug valves and needle instrument valves. The function of the stop valve is to control the on-off of the controlled fluid circuit or system pipeline. [0003] The existing pressure regulating valve has low pressure resistance, poor pressure ...

AI Technical Summary

Problems solved by technology

[0003] For the existing pressure regulating valve, it has low pressure resistance, poor pressure control accuracy, poor sealing effect and reliability, manual operation, large volume, and inconvenient maintenance

For commonly used stop valves, the sealing accuracy is poor, the reliability is poor, manual operation is adopted, the volume is large, and maintenance is inconvenient
