Abstract

The invention provides a fusible plug operating temperature and anti-extrusion test pressurizing device comprising an internal threaded joint (10) which is used for installing a fusible plug (40), a connecting pipe (20) which includes a connector connected with a fast testing joint (50), and a gas control valve (30) which is connected between the internal threaded joint (10) and the connecting pipe (20) and is used for controlling on-off of the air passage of the internal threaded joint (10) and the connecting pipe (20). The fusible plug operating temperature and anti-extrusion test pressure device can prevent the hidden safety troubles of gas leakage and fast testing joint fly-off during fusible plug operating temperature and anti-extrusion pressurization testing in the prior art.

Description

technical field [0001] The invention relates to the field of pressure testing of fusible plugs, in particular to a pressure device for fusible plug action temperature and anti-extrusion tests. Background technique [0002] The fusible plug is a non-repeatable, detachable pressure relief device that operates through the flow or melting of the fusible alloy installed in the plug hole. Under normal circumstances, the plug hole is closed. At a given temperature, the fusible alloy in the plug hole flows or melts, and the medium is released to release the pressure of the pressure vessel, so as to prevent accidents caused by the medium in the pressure vessel due to temperature rise and overpressure. [0003] The fusible plug has an operating temperature, and the operating temperature refers to the temperature of the thermostat when the fusible alloy in the fusible plug flows or melts during the test. [0004] figure 1 It is a schematic diagram of inflating and pressurizing the ex...
