A device and method for measuring explosion vent distance of pipe gallery

Abstract

The invention relates to a device for measuring the explosion venting distance of a pipe gallery and a measuring method thereof. The measuring device includes a vacuum pump, a knob valve, a pipe gallery, an explosion vent, a well cover, a heavy pressure object, a pressure gauge, an igniter, a gas storage cylinder, and a knob valve , pressure reducing valve, pressure gauge and knob valve; the vacuum pump is connected to the knob valve, and the other end of the knob valve is connected to the pipe gallery. The well cover covers the explosion vent; there is a first pressure gauge and an igniter on the pipe gallery, and a knob valve, a pressure reducing valve and a second pressure gauge are arranged on the gas storage cylinder in sequence, and the gas storage cylinder is connected to the pipe gallery through the knob valve. connect. It can determine the appropriate explosion venting distance, so as to meet the requirements of explosion venting safety, and at the same time, set less explosion venting ports to meet the requirements of economy.

Description

technical field [0001] The invention belongs to the technical field of gas explosions in narrow and long spaces, and relates to a measuring device and a measuring method for the explosion venting distance of a pipe gallery. Background technique [0002] With the acceleration of urbanization, urban underground pipelines are getting closer and closer to densely populated and important buildings such as residential areas, factories and schools, while criss-crossing and intricate underground pipeline corridors are laid with various important and important buildings such as oil and gas, gas, etc. Dangerous pipelines, once an explosion accident occurs, will cause huge casualties and bad social impact. The problem of insufficient safety distance of oil and gas pipelines will continue to exist for a long time, and when oil and gas leak into the pipeline gallery and gather and explode, it will inevitably pose a serious threat to the safety of the people. In order to reduce the serio...

AI Technical Summary

Problems solved by technology

[0003] Existing studies have done a lot of research on the explosion venting characteristics and devices of cylindrical pipes, such as the discussion on the influence of explosion venting methods on the explosion venting pressure, such as the research on the effect of explosion venting area on the pressure of the explosion venting process of cylindrical vessels, but there is no To study the determination of the appropriate explosion venting distance for the underground pipe gallery, for this reason, a device and method for measuring the explosion venting distance of the pipe gallery are needed to solve the above-mentioned problems in the prior art, so that it can determine the appropriate explosion venting distance. distance, so as to meet the safety requirements of explosion venting, and at the same time, set less explosion venting ports to meet the requirements of economy
