Abstract

The invention discloses an on-line irregular valve pressure testing system and a testing method. The testing system comprises a rack, a clamping device, a water pressure testing device, an air pressure testing device and a monitoring device, wherein the water pressure testing device comprises a water supply mechanism, a pressurizing mechanism and a pressure release mechanism. The testing method comprises the following steps: I, carrying out preparation before testing; II, defining an irregular valve, and confirming an irregular valve clamped area; III, clamping the irregular valve; IV, testingthe intensity and pressure of the valve; V, testing the sealing pressure of the valve; VI, dismounting and labeling the tested irregular valve. The system is reasonable in design simple and convenient to use and operate, good in use effect, capable of simply, conveniently and rapidly completing testing on intensity and pressure of multiple irregular valves and sealing pressure of the valves, highin security and accurate in testing.

Description

technical field [0001] The invention belongs to the technical field of special-shaped valve testing, and in particular relates to a special-shaped valve pressure online test system and a test method. Background technique [0002] Special-shaped valves are a general term for small-diameter valves with complex shapes. The nominal diameter of special-shaped valves is DN3-DN40, and the nominal pressure of special-shaped valves is 1.6MPa-42.0MPa. The special-shaped valve is an indispensable and important part to ensure the production and construction of oil and gas fields. To ensure that the special-shaped valve can be better used in the harsher oil and gas field production and construction process, the pressure of the special-shaped valve is tested to obtain the pressure of various special-shaped valves. The application environment of the special-shaped valve meets the requirements of the special-shaped valve itself, and improves the construction management of the oil and gas fi...
