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
The present invention relates to a kind of proving installation, particularly relate to a kind of valve hot test device.
Background technology
Existing valve detection method is to carry out pressure test, is mainly casing rigidity test and the impermeability test of valve.For a long time, pressure test method both domestic and external all carries out at normal temperatures, differ greatly with the temperature under actual condition, therefore cannot accurately record the quality condition under valve actual condition, and valve is under the working environment of High Temperature High Pressure, its material is easy to occur creep, causes some valves qualified in cold test to apply to after actual working environment, occurs the situations such as leakage.
Summary of the invention
The shortcoming that can only carry out at normal temperatures in order to overcome existing valve pressure test, the invention provides a kind of valve hot test device that can simulated condition.
The technical solution adopted for the present invention to solve the technical problems is a kind of valve hot test device, comprise tested valve, water pump, buffer tank, pressure regulator valve, pressure transducer A, pressure transducer B, stop valve A, stop valve B and water tank, water pump is connected with buffer tank, after buffer tank, be connected with pressure regulator valve in turn, stop valve A, pressure transducer A and tested valve, after tested valve, be connected to successively pressure transducer B, stop valve B, water tank, water tank is connected with water pump, between above-mentioned each parts, all by pipeline, connect, tensimeter and safety valve are housed on buffer tank, between pressure transducer A and stop valve A, thermometer A is installed, between pressure transducer B and stop valve B, thermometer B is installed, on pipeline between thermometer A and stop valve A, electric heater A is installed, on pipeline between thermometer B and stop valve B, electric heater B is installed.
Thermometer A and thermometer B are thermocouple temperature measurement instrument.
Electric heater A and electric heater B are tube electric heater.
The invention has the beneficial effects as follows:
1, actual condition can be simulated, thereby the quality condition of valve under actual condition can be accurately recorded;
2, this proving installation is Open architecture, goes for the valve of polymorphic type, many specifications;
