Hydraulic control one-way valve with pressure monitoring function

Abstract

The invention relates to a hydraulic control one-way valve with a pressure monitoring function. The hydraulic control one-way valve comprises a hydraulic control one-way valve body, wherein the hydraulic control one-way valve body, a liquid-penetrating plate and a mining intrinsic safety type digital pressure gauge are connected with each other through connecting bolts; the hydraulic control one-way valve body is led to the mining intrinsic safety type digital pressure gauge through a liquid hole in the liquid-penetrating plate; the mining intrinsic safety type digital pressure gauge is composed of a pressure gauge valve body, a circuit board, a sensor, an LED display panel, a networking module and an antenna; a pressure-measuring port communicated with the liquid hole in the liquid-penetrating plate is formed on the pressure gauge valve body; the sensor is arranged in the pressure-measuring port; the sensor is connected with the circuit board; the circuit board is respectively electrically connected with the LED display panel, the networking module, a first button and a second button; the networking module is connected with the antenna. The hydraulic control one-way valve is applied to a fully mechanized coal mining face hydraulic bracket for controlling a lifting column of a vertical column.

Description

technical field [0001] The invention relates to a hydraulically controlled one-way valve, in particular to a hydraulic support for controlling the lifting column of a large fully mechanized mining face in a coal mine, while monitoring and recording the pressure value of the hydraulic support, which can realize the function of automatically collecting and recording the impact pressure of the roof Pilot-operated check valve with pressure monitoring function. Background technique [0002] In the existing technology, the structure of the hydraulic control check valve is various. With the development of comprehensive coal mining technology, supports with large mining height and high working resistance have been widely used. The pressure generated when the column lifting column and the roof are pressed must be monitored and recorded in time. Currently, a double-needle pressure gauge is generally used underground to display the pressure value of the column, which cannot display the...

[0002] In the existing technology, the structure of the hydraulic control check valve is various. With the development of comprehensive coal mining technology, supports with large mining height and high working resistance have been widely used. The pressure generated when the column lifting column and the roof are pressed must be monitored and recorded in time. Currently, a double-needle pressure gauge is generally used underground to display the pressure value of the column, which cannot display the pressure value in real time, let alone form a pressure curve. Reasonable analysis and use of the specific use conditions of the hydraulic system will prevent other hydraulic components from being properly protected. Due to the underground conditions, the maintenance and replacement of components after damage will be inappropriate, thus affecting the output of the coal mine.
