Description

Valve Pressure Checker {APPARATUS FOR TESTING VALVE PRESSURE}

The present invention relates to a valve pressure tester, and more particularly, to a valve pressure tester for pressure inspection of relief valves and safety valves, such as relief valves and check valves, which are installed inside various mechanical equipments.

In general, various machines are provided with a safety valve to automatically operate when the pressure of the equipment or pipe exceeds a certain pressure to prevent the pressure rise, various valves are used in the machine.

The safety valve is a very important safety device that prevents the destruction of equipment and piping by reducing the pressure by operating when overpressure occurs.If the safety valve installed has a problem with its performance, such as leaking or not operating at the working pressure, it is very important. It may cause a great danger.

In this regard, conventionally, there is a problem that a pressure test is performed only during comprehensive repair of equipment without a separate pressure test on a pressure valve and a safety valve such as a relief valve and a check valve. That is, there is no specific device for pressure checking until all the equipment is disassembled and repaired, which is a great limitation in supporting equipment maintenance.

In addition, the existing pressure checker has a problem in that it is large in size, high in price, and inconvenient to use.

Therefore, there is a need for a valve pressure inspection device that can prevent a large accident of equipment that may occur due to abnormal operation or defect of the pressure valve or safety valve.
