DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a high-pressure plunger pump valve lifting tool, including a force baffle 1, a threaded groove 2 is arranged on the force baffle 1, a threaded column 3 is arranged in the threaded groove 2, a lifting head 4 is arranged on one side of the threaded column 3, a limiting position edge 5 is arranged between the lifting head 4 and the force baffle 1, a rotating groove 6 is arranged on the threaded column 3, and a rotating column 7 is rotatably arranged in the rotating groove 6.

[0026] like Figure 3 As shown, the lifting head 4 includes a lifting head base 401, and a groove 402 is provided on the lifting head base 401;

[0027] A rotating disk 403 is rotatably disposed in the groove 402, a plurality of guide slots 404 are obliquely disposed on the rotating disk 403, and a guide slide post 405 is movably disposed in the guide slots 404;

[0028] The inner wall of the groove 402 is provided with a plurality of first through grooves 406 , in which a support column 407 is slidably provided, and an adjustment plate 408 is provided on the support column 407 . A second through groove 409 is provided on one side of the lifting head base 401 .

[0029] Through the above technical solution, when it is necessary to adjust the position of the adjustment plate 408 according to the size of the pump valve, firstly, the rotating disk 403 is rotated by the rotating column 7, and the rotating disk 403 drives the support column 407 to move through the guide groove 404 and the guide slide column 405, and uses the first through groove 406 for guidance, so that the support column 407 moves toward or away from the second through groove 409, and the support column 407 drives the adjustment plate 408 to move, and the position of the adjustment plate 408 is adjusted to adapt to pump valves of different sizes.

[0030] like Figure 4 and Figure 5 As shown, the adjustment plate 408 includes an adjustment plate base 40801, a slide groove 40802 is provided on the adjustment plate base 40801, a lifting plate 40803 is slidably provided in the slide groove 40802, and a spring 40804 is fixedly provided on one side of the lifting plate 40803;

[0031] A slope 40805 is provided on one side of the lifting plate 40803 away from the slide groove 40802 , and a plurality of balls 40806 are rotatably provided on the slope 40805 .

[0032] Through the above technical solution, when the pump valve needs to be lifted, the lifting plate 40803 is first placed under the pump valve. During this process, the pump squeezes the inclined surface 40805, and the ball 40806 reduces the friction force, so that the lifting plate 40803 moves into the slide groove 40802, and the spring 40804 contracts. When the lifting plate 40803 reaches the bottom of the pump valve, the spring 40804 rebounds, so that the lifting plate 40803 fits the bottom of the pump valve, and then the pump valve can be lifted.

[0033] Working principle:

[0034] The present invention firstly rotates the rotating disk 403 by means of the rotating column 7, and the rotating disk 403 drives the support column 407 to move through the guide slot 404 and the guide slot 405, and uses the first through slot 406 for guidance, so that the support column 407 moves toward or away from the second through slot 409, and the support column 407 drives the adjustment plate 408 to move, and adjusts the position of the adjustment plate 408 to adapt to pumps and valves of different sizes, and then places the force baffle 1 on the upper plane of the pump head, and then rotates the threaded column 3, and puts the lifting head 4 into the lower part of the pump valve through the threaded column 3 and the threaded groove 2, so that the lifting plate 40803 fits the bottom of the pump valve, and then rotates the threaded column 3 in the opposite direction, and drives the pump to move through the lifting plate 40803 to lift the valve, which can adapt to pumps and valves of different sizes and expand the scope of application.

[0035] Among them, when it is necessary to adjust the position of the adjustment plate 408 according to the size of the pump valve, firstly, the rotating disk 403 is rotated by the rotating column 7, and the rotating disk 403 drives the support column 407 to move through the guide groove 404 and the guide slide column 405, and uses the first through groove 406 for guidance, so that the support column 407 moves toward or away from the second through groove 409, and the support column 407 drives the adjustment plate 408 to move, and adjusts the position of the adjustment plate 408 to adapt to pump valves of different sizes.

[0036] When the pump valve needs to be lifted, first put the lifting plate 40803 into the lower part of the pump valve. During this process, the pump squeezes the inclined surface 40805, and the ball 40806 reduces the friction force, so that the lifting plate 40803 moves into the slide groove 40802, and the spring 40804 contracts. When the lifting plate 40803 reaches the lower part of the pump valve, the spring 40804 rebounds, so that the lifting plate 40803 fits the bottom of the pump valve, and then the pump valve can be lifted.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
