One-way valve opening pressure detecting device and detecting method thereof

Abstract

A one-way valve opening pressure detecting device and a detecting method thereof are disclosed. The device comprises a one-way valve clamp, a damping rod, a pressure gauge, a gas-liquid conversion boxand a diad. The diad is connected to an air inlet of the gas-liquid conversion box through a pipeline, and an oil outlet of the gas-liquid conversion box is connected to one end of the damping rod through the pipeline, and the other end of the damping rod is connected to the one-way valve clamp through the pipeline. The pressure gauge is installed on the damping rod, and the one-way valve clamp is provided with a connecting gas rod assembly, an oil hole in the connecting gas rod assembly is connected to an upper end surface of the one-way valve clamp, and an oil injection section of the connecting gas rod assembly is connected to the pipeline between the one-way valve clamp and the damping rod. A lot of complicated calculations of a force applied to a front portion of a one-way valve arereduced, and through simply replacing the damping rod, an opening effect of a plurality of preposition resistances acting on the one-way valve can be achieved. Air is used as a power source to simulate working pressure when a compressor exhausts, and air pressure is converted into hydraulic pressure by a simple device so that resources are saved and cost is reduced.

Description

technical field [0001] The invention relates to the field of pressure detection, in particular to a check valve opening pressure detection device and a detection method thereof. Background technique [0002] The check valve is a directional control valve, and it can also be used as a pressure maintaining valve to ensure the opening pressure of the valve body. One of its functions is to ensure that the internal fluid can only flow in a single direction and cannot flow back. The second is to have a certain opening pressure to ensure the stability of the internal medium pressure. In this way, it is necessary to ensure that the reverse sealing performance of the one-way valve is reliable. A set of stable pressure detection device is also needed for pressure detection to ensure stable and reliable pressure. [0003] The article "Design of Check Valve Leakage Detection Device" briefly describes a design scheme for quickly and accurately judging the seal performance of check val...

AI Technical Summary

Problems solved by technology

[0005] If the detection scheme of the check valve in the existing technology is used to detect the check valve for the compressor, a large number of hydrodynamic calculations are required, and complex calculations require high-level technical personnel to provide corresponding technical support, and it is difficult To achieve accurate calculation results, it is easy to cause wrong judgments and waste manpower and material resources
