[0018] Example

[0019] Please refer to Figure 1-Figure 4A quick-install fracturing pump valve box comprises a box body 1 and a pump valve body 2. A high-pressure shell 3 is installed on the outside of the pump valve body 2. The pump valve body 2 adopts the pump body in the prior art. Two groups of symmetrical arc plates 4 are arranged on the inside of the box body 1. The inner side of the arc plate 4 has a plurality of fixed blocks 41. The plurality of fixed blocks 41 are evenly distributed on the circumference of the inner side of the arc plate 4. A plurality of fixed blind holes 30 are opened on the outside of the high-pressure shell 3. The fixed blind holes 30 are matched with the fixed blocks 41, that is, the fixed blocks 41 can be inserted into the fixed blind holes 30. A positioning component is arranged on the outside of the box body 1. When the pump valve body 2 is limitedly inserted into the inside of the box body 1 and is located between the two arc plates 4, the positioning component can drive the fixed blocks 41 on the two arc plates 4 to move closer to or away from the fixed blind holes 30.

[0020] In an optional embodiment: the positioning assembly includes a semi-arc frame 5, an L-shaped connecting rod 51 and a threaded rod 52, the semi-arc frame 5 is fixedly installed on the outside of the box body 1, the threaded rod 52 is rotatably connected to the inside of the semi-arc frame 5, both ends of the semi-arc frame 5 are opened, one end of the two L-shaped connecting rods 51 is symmetrically threadedly connected to the threaded rod 52, and both sides of the box body 1 are provided with grooves 100 that are compatible with the L-shaped connecting rod 51, and the other end of the L-shaped connecting rod 51 passes through the semi-arc frame 5 and the groove 100 in turn to be fixedly connected to the arc plate 4.

[0021] In an optional embodiment: a guide rod 53 is fixedly connected to the inside of the arc plate 4, and the guide rod 53 is arranged parallel to the threaded rod 52. One end of the two L-shaped connecting rods 51 are slidably sleeved on the surface of the guide rod 53, and one end of the threaded rod 52 extends to the outside of the semi-arc frame 5 and is fixedly connected to a turning handle. Specifically, the two L-shaped connecting rods 51 can be limited by the guide rod 53 so that the L-shaped connecting rod 51 can move stably, and the threaded rod 52 can be easily rotated by the turning handle. Two groups of threads with opposite directions are arranged on the threaded rod 52, and the inner side wall of one end of the L-shaped connecting rod 51 matches the thread. When the threaded rod 52 rotates, the two L-shaped connecting rods 51 can move toward or away from each other.

[0022] In an optional embodiment: a buffer layer 411 is fixedly connected to the outer side surface of a portion of the fixed block 41, and the buffer layer 411 is made of rubber material. When the portion of the fixed block 41 with the buffer layer 411 is inserted into the through hole 31, the buffer layer 411 can provide a buffer between the arc plate 4 and the high-pressure shell 3, thereby providing a buffer effect on the pump valve body 2.

[0023] In an optional embodiment: a plurality of through holes 31 are provided on the high-pressure shell 3, and the through holes 31 pass through the inner and outer sides of the high-pressure shell 3.

The bottom end of the high-pressure shell 3 has an insert block adapted to the limiting groove 10, that is, the insert block can be inserted into the limiting groove 10, so that when the high-pressure shell 3 is inserted into the box body 1, it can be limited inside the box body 1, and when the insert block at the bottom of the high-pressure shell 3 is inserted into the inside of the box body 1, each fixing block 41 is coaxially aligned with a fixed blind hole 30.

[0025] Specifically, when the high-pressure shell 3 is installed into the box body 1, first insert the insert block at the bottom of the high-pressure shell 3 into the limit groove 10, so that the high-pressure shell 3 and the pump valve body 2 are limitedly inserted into the interior of the box body 1, and then turn the handle by hand to drive the threaded rod 52 to rotate, driving the multiple fixed blocks 41 on the two arc plates 4 to move toward each other synchronously, so that the multiple fixed blocks 41 are synchronously inserted into the fixed blind holes 30 on each high-pressure shell 3, and the multiple fixed blocks 41 are limitedly fixed at various positions on the outer circumference of the high-pressure shell 3, so that the pump valve body 2 placed in the high-pressure shell 3 can be quickly and stably fixed to the inside of the box body 1.

[0026] Furthermore, by inserting the buffer layers 411 on the plurality of fixing blocks 41 into the fixing blind holes 30 , a buffering effect can be exerted on the high-pressure shell 3 , thereby preventing the pump valve body 2 from being damaged by collision.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
