According to the present invention, a wellhead nut 20 is provided at a first end (right end in fig. 1) of the main body screw 10. As shown in fig. 1, the outer side of the sidewall of the wellhead nut 20 is fixedly connected to the end of the first end of the body screw 10, so that the direction of the threaded hole of the wellhead nut 20 is perpendicular to the axial direction of the body screw 10. In one embodiment, the wellhead nut 20 is fixedly connected to the body screw 10 by welding. The function of the wellhead nut 20 will be described below.
As shown in fig. 1, a screw thread is provided on an outer wall of a second end (left end in fig. 1) of the body screw 10. The threads are arranged to extend axially inward from the second end of the body screw 10. The function of the thread will be described below.
According to the present invention, the dismounting tool further comprises a clamping member 30. The clamping member 30 is used for clamping the valve body of the water injection pump combination valve to be disassembled. As shown in fig. 1, a clamping member 30 is attached to the second end of the body screw 10. The clamp member 30 includes 2 clamp arms 31 arranged in parallel and a coupling nut 32 for coupling the 2 clamp arms 31. The same end of each of the 2 holding arms 31 is fixedly connected with the connecting nut 32, and the 2 holding arms 31 are connected to the radial outer side of the connecting nut 32 opposite to each other. Thereby, the 2 clamp arms 31 form a clamp structure having the coupling nut 32 as a rotation center. The direction of the screw hole of the coupling nut 32 coincides with the longitudinal direction of the clamp arm 31. The clamping member 30 can be fittingly mounted with threads of the second end of the screw body 10 by a coupling nut 32, thereby coupling the clamping member 30 to the second end of the screw body 10. The removal tool 100 can adjust the axial length of the removal tool 100 according to actual needs by adjusting the connection position of the body screw 10 and the connection nut 32. In one embodiment, the clamping arm 31 is fixedly connected to the coupling nut 32 by welding.
In the present embodiment, the gripper arm 31 is configured in an elongated plate shape. The clamping arms 31 have a certain elasticity so that the opening angle between the 2 clamping arms can be adjusted, and the snap-in part 33 (see below) can be snap-in connected to the axial inner side of the guide sleeve of the water injection pump valve body.
According to the present invention, the clamping arms 31 are provided with engaging portions 33 at ends thereof remote from the coupling nut 32. The engaging portions 33 of the 2 gripper arms 31 are disposed opposite to each other, thereby forming an engaging structure. In one embodiment, the engaging portion 33 is made of an iron piece. The working surface of the engagement portion 33 is configured in a circular arc shape so that the engagement portion 33 can conform to the contour of the water injection pump valve body on the inner side in the axial direction of the guide sleeve.
Further, the thickness of the engaging portion 33 is set to be equal to the projecting width of the guide sleeve of the water injection pump valve body. The engagement portion 33 is formed in a zigzag shape in cross section, so that the engagement portion 33 can engage with the guide bush concave ring while engaging with the spring of the water injection pump located on the inner side in the axial direction of the guide bush. This configuration of the snap-in part 33 facilitates a snap-in connection between the snap-in part 33 and the water filling pump valve body, thereby enhancing the clamping connection between the snap-in part 33 and the water filling pump valve body. Meanwhile, the clamping member 30 can be guaranteed to generate uniform tension on the water injection pump valve body during disassembly, and the water injection pump valve body is effectively prevented from being clamped due to oblique tension when the water injection pump valve body is discharged from the cylinder. This is very advantageous in reducing the difficulty of operation of the removal tool 100 and improving the removal efficiency.

The 2 clamp arms 31 are provided with through holes corresponding thereto, and the through holes are provided axially inward of the engaging portions 33. Preferably, the through-hole is provided in a region of the clamp arm 31 near the middle. An adjusting bolt assembly 34 passes through the through hole, and the clamping degree of the clamping member 30 to the valve body of the water injection pump can be adjusted through the adjusting bolt assembly 31. This enables the engaging portion 33 to clamp the guide bush, thereby preventing displacement. Adjusting bolt subassembly 34 can effectively adjust the tight degree of clamp of block portion 33 to the water injection pump valve body to effectively guarantee to form firm the connection between block portion 33 and the water injection pump valve body when dismantling. This can effectively prevent the engagement portion 33 and the water injection pump valve from coming loose, and thus prevent the engagement portion 33 and the water injection pump valve from coming off.
According to the present invention, the clamping member 30 further comprises a force applying rod (not shown) for applying a pulling force. The pressurizing rod is used for passing through the wellhead nut 11 of the first end of the body screw rod 10, applying horizontal tension through the pressurizing rod, and pulling out the water injection pump valve body through the body anchor rod 10 and the clamping member 30, thereby completing disassembly. In one embodiment, the stressing rod is a copper rod.
According to the utility model discloses a extracting tool 100 struts the aperture of centre gripping arm 31 in order to adjust clamping member 30 when the actual work to connect the tip block 33 block of clamping member 30 at the axial inboard of the water injection pump valve body of treating the dismantlement, thereby make block 33 form the block to the water injection pump valve body. Thereafter, the clamping degree of the clamping arm 31 is adjusted by adjusting the adjusting bolt assembly 34, so that the holding engaging portion 33 forms a firm engagement connection with the water injection pump valve body. Then, the stress application rod passes through the wellhead nut 11 at the first end of the main body screw 10, and applies horizontal pulling force to the stress application rod, and then the water injection pump valve body is taken out from the water injection pump combined valve cylinder body through the disassembling tool 100, thereby completing the disassembling.
