Abstract

The invention discloses a hydraulic drive type clamping heterotype valve explosion pressure test system and test method. The hydraulic drive type clamping heterotype valve explosion pressure test system includes a hydraulic drive type clamping device, a quick connector plug, an explosion pressure testing device and a monitoring device, wherein the explosion pressure testing device includes a watersupply box, a liquid supply pipe, a pressurization mechanism and a pressure release mechanism. The hydraulic drive type clamping heterotype valve explosion pressure test method includes the followingsteps: 1) preparing before testing; 2) defining a heterotype valve and determining a clamped area of the heterotype valve; 3) determining the number of clamping rods contacting the clamped area; 4) clamping the heterotype valve and connecting a quick connector plug; 5) determining whether clamping of the tested heterotype valve is stable; 6) testing the explosion pressure of the heterotype valve;and dismounting the heterotype valve. The hydraulic drive type clamping heterotype valve explosion pressure test system and test method have the advantages of being reasonable in design, being simplein operation, being stable in clamping of the heterotype valve so as to prevent the heterotype valve from deformation, guaranteeing accuracy of the explosion pressure test of the heterotype valve, and being high in practicality.

Description

technical field [0001] The invention belongs to the technical field of valve testing, and in particular relates to a method for testing the burst pressure of a hydraulically driven and clamped special-shaped valve. 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 harsh oil and gas field production and construction process, the burst pressure of the special-shaped valve is tested to obtain the burst pressure of various special-shaped valves. So that the application environment of the special-shaped valve can meet the requirements of the special-shaped valve itself, and improve the constructi...
