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 now, there is a lack of a pneumatically driven clamping method for special-shaped valves, which can stably clamp special-shaped valves, reduce the deformation of special-shaped valves caused by clamping, and meet the requirements of clamping tests for special-shaped valves

Embodiment Construction

[0080] Such as Figure 1-Figure 4 as well as Figure 5A-Figure 5H A clamping method for a pneumatically driven special-shaped valve is shown. The device used in the method includes a pneumatic clamping device for clamping the measured special-shaped valve 11 and a monitoring device for monitoring the pneumatic clamping device. The pneumatic clamping device includes a clamping mechanism and a pneumatic clamping drive mechanism that drives the clamping mechanism to clamp the measured special-shaped valve 11. The pneumatic clamping drive mechanism is a clamping cylinder, and the clamping cylinder includes a cylinder body 2 and a piston rod 4 with one end protruding from the cylinder body 2, the clamping mechanism includes a fixed clamping plate 3 fixedly connected with the cylinder body 2, a fixed clamping plate 3 that is sleeved on one end of the piston rod 4 and can be close to or away from the fixed clamping plate 3 The moving clamping plate 5, the fixed clamping plate 3 and ...

Abstract

The invention discloses a clamping method of an air pressure drive type special-shaped valve. The method comprises the following steps of firstly, preparation work before test; secondly, special-shaped valve defining and determining of the clamped area of the special-shaped valve; thirdly, clamping of the special-shaped valve; fourthly, judging whether clamped of the tested special-shaped valve isstable or not; fifthly, detaching of the special-shaped valve. The method is simple in step, implementing is convenient, the special-shaped valve is stably clamped, the deformation of clamping to thespecial-shaped valve is reduced, clamping test needs of the special-shaped 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 method for clamping a pneumatically driven 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 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...
