Abstract

The invention relates to a skid-mounted device for testing lives of small-bore gauge valves under high-temperature and high-pressure conditions. The device comprises a rack, a test platform, a heating and pressure circulating system, a test executing mechanism and a control system, wherein the heating and pressure circulating system comprises a water storage tank, a circulating pump, a condensate water tank, valves and a steam reaction kettle; the test executing mechanism comprises a servo motor and a lifting device; the control system comprises a human-computer interaction interface as well as a data acquisition, transmission and processing module. The device is simple in structure, small in occupied area, high in adaptability to fields and higher in automation capability, the problem of high-temperature and high-pressure medium sources is effectively solved, life test requirements of the small-bore gauge valves under different pressure and temperature conditions are met, production and usage costs of a test system are reduced, besides, the accuracy of test data is improved, and test work can be conducted through remote control, so that the interaction capability of the test equipment data is further improved.

Description

Technical field [0001] The invention relates to a skid-mounted small-caliber instrument valve high temperature and high pressure life test device, which belongs to the technical field of stop valve test equipment. Background technique [0002] Small caliber instrument valve (usually DN≤25mm) is a valve commonly used in nuclear power plants and power plant systems. It is widely used in reactor cooling systems, safety injection systems, waste heat export systems, and main steam systems. Because the valve is used in high temperature and high pressure applications Operating conditions, therefore, have high requirements for its performance. Therefore, the service life of small-caliber instrument valves under high temperature and high pressure conditions needs to be tested during the manufacturing process, but the existing test equipment has the following defects: (1 ) The caliber of the existing valve high temperature and high pressure test system is relatively too large, and the rela...
