Impact resistance test device of high-flow safety valve

Abstract

The invention relates to an impact resistance test device of a high-flow safety valve, which comprises a high-pressure pump station, a microcomputer data acquiring machine and a microcomputer measurement control / data processing system, wherein the microcomputer data acquiring machine is connected with the microcomputer measurement control / data processing system; the high-pressure pump station branches two paths by a precise filter and the two paths are respectively connected with two electromagnetic valves; the electromagnetic valves are connected with liquid source adapters; the liquid source adapters are connected with liquid control devices; the liquid control devices are connected with superchargers; the microcomputer data acquiring machine is connected with the electromagnetic valves, connected with the liquid control devices by energy accumulating pressure sensors, connected with the supercharger by a high-pressure sensor and the supercharger by a displacement sensor; the supercharger in one path is a large supercharger, and the supercharger in the other path is a medium supercharger; and energy accumulator groups are respectively connected with the two liquid source adapters. The invention simulates the dynamic process under the condition of working condition sinking and instant impact of an underground hydraulic bracket vertical column of the high-flow safety valve and tests the characteristic parameters of the safety valve.

Description

technical field [0001] The invention relates to an anti-shock performance test device of a mine hydraulic support safety valve, in particular to an anti-shock performance test device of a large-flow safety valve. Background technique [0002] At present, among the five major disasters in my country's coal mines, the proportion of roof accidents in underground working faces still occupies the first place. In some mining areas in my country, especially in recent years, a considerable number of mines in my country have entered deep mining, and there are threats of hard roofs and rock bursts. In modern mines, the requirements for high production and high efficiency make the advancing speed of the working face greatly accelerated, requiring the roof cantilever to be enlarged. These factors will increase the possibility of a series of dynamic disasters such as large-area roof collapse and violent impact, threatening the safety of production personnel. In order to achieve high yi...
