Abstract

The invention relates to a valve hot test device. A water pump is connected with a surge tank. A pressure regulating valve, a stop valve A, a pressure sensor A and a tested valve are sequentially connected behind the surge tank. A pressure sensor B, a stop valve B and a water tank are sequentially connected behind the tested valve. The components are all connected through pipelines. A pressure gauge and a safety valve are installed on the surge tank. A temperature gauge A is installed between the pressure sensor A and the stop valve A. A temperature gauge B is arranged between the pressure sensor B and the stop valve B. The pipeline between the temperature gauge A and the stop valve A is provided with an electric heater A and the pipeline between the temperature gauge B and the stop valve B is provided with an electric heater B. The valve hot test device has the advantages that an actual working condition can be simulated so that the quality condition of the valve can be accurately measured under the actual working condition; the valve hot test device is of an open structure so that the valve hot test device can be suitable for valves of different types and different specifications; temperature is automatically controlled through a thermocouple thermodetector, temperature is stable, and adjustment is convenient.

Description

technical field [0001] The invention relates to a test device, in particular to a valve thermal state test device. Background technique [0002] The existing valve detection method is to carry out a pressure test, that is, mainly a shell strength test and a tightness test of the valve. For a long time, the pressure test methods at home and abroad have been carried out at room temperature, which is very different from the temperature under actual working conditions, so it is impossible to accurately measure the quality of the valve under actual working conditions, and the valve is under high temperature and high pressure. Its material is prone to creep, which will cause some valves that pass the normal temperature test to leak when they are used in the actual working environment. Contents of the invention [0003] In order to overcome the disadvantage that the existing valve pressure test can only be carried out at normal temperature, the invention provides a valve the...
