[0029] Bolt 5 is rotatably mounted on connecting cover 3;

[0030] The crossbar 4 is slidably mounted on the valve box 1. The crossbar 4 is threadedly connected to the bolt 5 and one of the flanges 2 is fixed by the crossbar 4.

[0031] Upright rod 6 is slidably mounted on valve box 1. Horizontal rod 4 is connected to upright rod 6 through contact. Another flange 2 is fixed by upright rod 6.

[0032] A connecting groove 12 is provided on the valve box 1. The connecting groove 12 is provided on one side of the valve box 1 and the top of the valve box 1. The flange 2 is embedded in the connecting groove 12. A limit groove 21 is provided on the flange 2.

[0033] The mounting platform 11 has a horizontal groove 7, which is connected to the connecting groove 12. A sliding ridge 71 is provided in the horizontal groove 7. The horizontal groove 7 provides a sliding track for the crossbar 4. At the same time, the sliding ridge 71 is embedded in the sliding groove 42 of the crossbar 4 to prevent the crossbar 4 from rotating.

[0034] A sliding groove 42 is provided on the crossbar 4, and a sliding ridge 71 is embedded in the sliding groove 42. The crossbar 4 is slidably disposed in the horizontal groove 7. An inclined block 41 is provided on the crossbar 4, and the crossbar 4 can be embedded in the limiting groove 21. The crossbar 4 is threadedly connected to the bolt 5. Thus, by rotating the bolt 5, the movement of the crossbar 4 in the horizontal groove 7 can be precisely controlled, so as to quickly fix and loosen the flange 2.

[0035] The wing plates 61 are arranged on both sides of the vertical rod 6, and the spring 62 is arranged between the vertical rod 6 and the mounting table 11 through the wing plates 61, so that the vertical rod 6 has an automatic reset function, and the vertical rod 6 can be quickly reset when the inclined block 41 is reset, and the inclined surface is arranged at the upper end of the vertical rod 6 and matched with the inclined block 41, so that the vertical rod 6 can slide in the vertical groove 8 when the cross rod 4 moves, and then is embedded into the limiting groove 21 of the other flange 2, so that the quick fixing and loosening of the other flange 2 are realized, and the vertical rod 6 is abutted with the cross rod 4 through the inclined block 41, and the vertical rod 6 can be embedded into the limiting groove 21.

[0036] The vertical groove 8 is arranged on the mounting table 11 and extends into the connecting groove 12, and the vertical rod 6 is slidingly arranged in the vertical groove 8, so that the vertical groove 8 provides a sliding space for the vertical rod 6 and restricts the movement direction of the vertical rod 6, and ensures that the vertical rod 6 can be accurately embedded into and separated from the limiting groove 21 of the flange 2.

[0037] It should be noted that the working principle of the scheme for conveniently replacing and dismounting the valve box fluid end components is as follows: the mounting table 11 is arranged on the valve box 1, the connecting cover 3 is arranged on the mounting table 11, and the bolt 5 is rotationally connected to the connecting cover 3. The valve box 1 is provided with the connecting groove 12, and the flange 2 is embedded into the connecting groove 12, and the limiting groove 21 is arranged on the flange 2. The horizontal groove 7 on the mounting table 11 is communicated with the connecting groove 12, the sliding ridge 71 is arranged in the horizontal groove 7, the cross rod 4 is matched with the sliding ridge 71 through the sliding groove 42 and can slide in the horizontal groove 7, the inclined block 41 on the cross rod 4 enables the cross rod 4 to be embedded into the limiting groove 21 and be threadedly connected with the bolt 5, when the bolt 5 is rotated, the cross rod 4 moves in the horizontal groove 7 until the cross rod 4 is embedded into the limiting groove 21, so that one of the flanges 2 is fixed. The vertical groove 8 is further arranged on the mounting table 11, the vertical rod 6 is connected with the mounting table 11 through the wing plates 61 and the spring 62, and the upper end inclined surface of the vertical rod 6 is matched with the inclined block 41, when the cross rod 4 moves, the inclined block 41 pushes the vertical rod 6 to slide in the vertical groove 8, and the vertical rod 6 can be embedded into the limiting groove 21 of the other flange 2, so that the other flange 2 is fixed.

[0038] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it cannot be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and these all belong to the protection scope of the present application.
