Mobile steam safety valve thermal state test platform

Abstract

The invention provides a mobile steam safety valve thermal state test platform, which comprises a test terminal and a pressure relief test mechanism, the pressure relief test mechanism comprises a left closed cylinder, a middle movable closed cylinder and a fitting mechanism, and one end of the middle movable closed cylinder is provided with an annular closed groove. A middle movable sealing cylinder of the pressure relief testing mechanism can slide back and forth between a left sealing cylinder and an attaching half pipe, when the middle movable sealing cylinder and the attaching half pipe are closed under the cooperation effect of an annular sealing groove and a sealing half inserting pipe, a safety valve can be completely sealed inside, and at the moment, the safety valve can be sealed to be closed as long as the safety valve relieves pressure. The middle movable sealing cylinder is quickly separated from the fitting half pipe, and meanwhile, the real-time thermal state of the safety valve and the temperature during pressure relief can be detected, so that the purpose of testing the thermal state of the safety valve is achieved.

Description

technical field [0001] The invention belongs to the technical field of safety valve testing, in particular to a mobile steam safety valve thermal state testing platform. Background technique [0002] When using the mobile steam supply boiler to transport steam to the storage tank, a valve needs to be installed on the storage tank to supply steam to the storage tank. After the pressure reaches a certain value, the safety valve jumps. Therefore, when applied to the actual application environment, there may be deviations, which may cause the safety valve to release pressure earlier or later, which is not conducive to the safe operation of the storage tank. Therefore, it is necessary to detect the state of the safety valve to test whether For normal pressure relief, however, the existing mobile steam safety valve thermal test platform is not sensitive enough to test, and cannot accurately detect the real-time temperature of the safety valve and the temperature during pressure re...

AI Technical Summary

Problems solved by technology

[0002] When the mobile steam supply boiler is used to transport steam to the storage tank, a valve needs to be installed on the storage tank to supply steam to the storage tank. After the pressure reaches a certain value, the safety valve takes off. The safety valve is generally under normal temperature and pressure when it is tested at the factory. Therefore, when it is applied to the actual application environment, there may be deviations, which will cause the safety valve to release pressure in advance or delay, which is not conducive to the safe operation of the storage tank. Therefore, it is necessary to detect the state of the safety valve and test whether it is For normal pressure relief, however, the existing mobile steam safety valve thermal state test platform is not sensitive enough, nor can it accurately detect the real-time temperature of the safety valve and the temperature at the time of pressure relief. Therefore, the present invention proposes a Mobile steam safety valve thermal test platform
