Device and method for indirectly testing performance of fire detection tube

Abstract

The invention discloses a device and a method for indirectly testing the performance of a fire detection tube. A medium capable of generating high pressure gas is filled in a gas bottle of the device; one end of the tested fire detection tube is connected with the outlet of a pressure regulating valve, and the other end of the tested fire detection tube is sealed by an end connector; a test section at the center of the fire detection tube is fixed on a fixed plate; a cover plate is arranged on a test box; the fixed plate is positioned on the test box; a part of the fire detection tube on the fixed plate is soaked into the liquid medium; a timer is arranged on the lateral surface of the test box below the fixed plate; a heat source is arranged at one side of the test box and is completely soaked into the liquid medium; and a temperature testing element is arranged on the test box and is arranged in the liquid medium. The invention realizes the purpose of conveniently and accurately regulating the test pressure; when the fire detection tube is broken, gas can overflow out of the liquid medium and can not pollute the liquid medium; the indirect method which uses the liquid medium for simulating the heating environment in the working process of the fire detection tube has the advantages of high control accuracy of test temperature, simple structure, safe operation and low cost; and the device can be used as standard equipment to be popularized and used.

Description

technical field [0001] The invention relates to a testing device and method, in particular to a testing device and a testing method for fire-fighting pipes. Background technique [0002] The fire detection tube automatic fire extinguishing device is a brand-new fire-fighting equipment for detecting and extinguishing fires. The fire detection tube itself (direct type) or the nozzle (indirect type) is released into the protected area to extinguish the fire. This device can make up for the shortcomings of the existing fixed gas automatic fire extinguishing devices, and is used for fire protection in some special places. , In these places, due to the narrow space and special environment, it is impossible to install pipe networks, nozzles or fire alarm systems, so that the automatic fire extinguishing system cannot function. Large economic losses can be properly solved by using the unique fire extinguishing method of the fire detection tube automatic fire extinguishing device. ...
