Problems solved by technology

The current special-shaped valve adopts the upper and lower clamping top pressure type and the holding pressure type, which is not universal and cannot be clamped, and will cause the overall deformation of the special-shaped valve
But nowadays, there is a lack of a hydraulically driven special-shaped valve clamping method, which can stably clamp special-shaped valves, reduce the deformation of special-shaped valves caused by clamping, and meet the requirements of special-shaped valve clamping tests

Embodiment Construction

[0083] Such as Figure 1-Figure 4 as well as Figure 5A-5H A clamping method for a hydraulically driven special-shaped valve is shown. The device used in the method includes a hydraulic clamping device for clamping the measured special-shaped valve 12 and a monitoring device for monitoring the hydraulic clamping device. The hydraulic clamping device includes two symmetrically arranged hydraulic cylinders 2 and two sets of clamping parts respectively arranged on the two hydraulic cylinders 2, and each set of clamping parts includes a plurality of hydraulic cylinders that can shrink or extend at one end. The clamping rod 4 of the cylinder 2, a plurality of the clamping rods 4 are arranged in multiple rows and rows, the hydraulic cylinder 2 is connected with the hydraulic oil tank 6 through the oil supply pipe 15, and the oil supply pipe 15 is provided with an oil pump 8 , the first solenoid valve 17 and the hydraulic lock 19, the monitoring device includes a micro-controller 11...

Abstract

The invention discloses a hydraulic drive type abnormal valve clamping method. The method comprises following steps of step 1, preparation work before the test; step 2. Defining an abnormal valve anddetermining a clamped region of the abnormal valve; step 3, determining the quantity of clamp rods contacting with the clamped region; step 5, clamping of the abnormal valve; step 5, judging whether the clamping of the to-be-tested abnormal valve is stable; and step 6, disassembly of the abnormal valve. According to the invention, the steps are simple; the method is simple to achieve; abnormal valves can be stably clamped; deformation on the abnormal valves caused by clamping is reduced; test requirements on clamping of the abnormal valve are met; and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of special-shaped valve clamping, and in particular relates to a hydraulically driven special-shaped valve clamping 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 to DN40, and the nominal pressure of special-shaped valves is 1.6MPa to 19.0MPa. The special-shaped valve is an indispensable and important part to ensure the production and construction of the oil and gas field. The strength and sealing of the special-shaped valve are tested to make the application environment of the special-shaped valve meet the requirements of the special-shaped valve itself and improve the construction management of the oil and gas field surface engineering. In the quality inspection of special-shaped valves, it is very important to carry out pressure tests on special-shaped valves to test the stre...
