Detailed Description

The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the utility model and together with the description, serve to explain the principles of the utility model and not to limit the scope of the utility model.

A pressure pump valve body taking-out tool comprises a sleeve 1, a threaded rod 2 rotating with one end of the sleeve 1 and a clamping assembly fixedly arranged at the other end of the sleeve 1, wherein the clamping assembly comprises a positioning seat fixedly connected with the other end of the sleeve 1 and a clamping seat 32 fixedly connected with one end of the threaded rod 2 and arranged in the sleeve 1, the positioning seat comprises a connecting plate 311 and a fixing head 312 integrally formed with the connecting plate 311, the positioning seat is fixedly connected with the other end of the sleeve 1 through the connecting plate 311, the fixing head 312 extends into the sleeve 1, a chamfer area 313 is arranged at the upper end of the fixing head 312, a positioning hole 314 is arranged in the fixing head 312, a locking hole 321 is formed in the clamping seat 32, a chamfer boss 322 matched with the chamfer area 313 is arranged at the upper end of the locking hole 321, by turning the threaded rod 2, the chamfered boss 322 in the clamping seat 32 is driven to press against the chamfered area 313 on the fixed head 312, which allows the fixed head 312 to clamp the pump valve protrusion.

In one embodiment, the outer wall of the fixing head 312 is provided with threads, the inner wall of the locking hole 321 is provided with thread grooves matched with the threads, the other end of the threaded rod 2 is provided with a rotating hand wheel 21, and the positioning seat is made of fluororubber. The threaded rod 2 is driven to rotate by rotating the hand wheel 21, threads on the outer wall of the fixing head 312 are matched with thread grooves in the inner wall of the locking hole 321, the chamfering boss 322 extrudes the chamfering area 313 on the fixing head 312, and the chamfering area 313 can deform in the extruding process due to the fact that the positioning seat is made of fluororubber, and the protruding portion of the fracturing pump is fixed.

In order to ensure that the centers of the positioning hole 314 and the locking hole 321 are on the same axis, specifically, a limiting plate 11 is disposed at an end of the sleeve 1 close to the positioning seat 31, and an end of the threaded rod 2 passes through the limiting plate 11 and is fixedly connected with the clamping seat 32.

In order to further clamp the protruding portion of the valve body, specifically, a layer of anti-slip pad 4 is disposed on the inner wall of the positioning hole 314, a plurality of protrusions 41 are disposed on the inner wall of the anti-slip pad 4, and the anti-slip pad 4 is made of silicon rubber. The silicon rubber has a certain friction force, and the arrangement of the protrusion 41 can further increase the friction force between the protruding part of the valve body and the fixing head 312.

In one embodiment, a supporting plate 12 is disposed at an end of the outer wall of the sleeve 1 away from the positioning seat 31, and a compression spring 315 is sleeved on the fixing head 312. By arranging the compression spring 315, a buffering effect can be achieved, and the phenomenon that the fixing head 312 is damaged due to extrusion caused by the fact that the chamfering area 313 on the fixing head 312 is extruded by the chamfering boss 322 in the clamping seat 32 is too tight is avoided.

The working principle is as follows: one end of the sleeve 1, provided with the clamping component, extends into a pump cavity through a fracturing pump maintenance hole, the protruding part of the valve body is inserted into the positioning hole 314, and the threaded rod 2 is rotated to drive the chamfer boss 322 in the clamping seat 32 to extrude the chamfer area 313 on the fixing head 312 to fix the protruding part of the valve body; the sleeve 1 is lifted up to separate the valve body from the valve seat and take out the valve body from the pump cavity.

The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
