[0033] In related technologies, the valve core of the check valve in a diaphragm pump suffers from low disassembly efficiency. This application provides a tool for disassembling and assembling the valve core of a check valve, which can at least partially solve the problem of low disassembly efficiency of the valve core in the check valve of a diaphragm pump.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] like Figure 1 As shown, the valve core 200 of the one-way valve of the diaphragm pump includes a threaded valve nut 210 and a valve cone 220. The one-way valve core disassembly and assembly tool 100 includes a support base 110, a limiting component 120, and a tightening component 130. The limiting component 120 is mounted on the support base 110 and is used to limit the valve cone 220. The tightening component 130 is disposed opposite to the limiting component 120, and the end of the tightening component 130 near the limiting component 120 has an abutment portion 1311 for abutting against the valve nut 210.

[0036] When using the disassembly and assembly tool 100 of this application, the support base 110 can be fixed on a maintenance platform or the ground, etc. The limiting component 120 is fixedly connected to the support base 110 to limit the valve cone 220, preventing it from rotating around the axis with the valve nut 210. The tightening component 130 is arranged opposite to the limiting component 120. The tightening component 130 can rotate; it can be driven by an operator or by hydraulic, electric, or other means. The tightening component 130 has an abutment portion 1311. When the tightening component 130 rotates, the abutment portion 1311 abuts against the surface of the valve nut 210, applying force to the valve nut 210, causing it to rotate relative to the valve cone 220, thereby separating and connecting the valve nut 210 and the valve cone 220. With this design, the valve cone 220 is limited by the limiting component 120, and the valve nut 210 is subjected to force by the abutment part 1311 of the screwing component 130, so that the valve cone 220 and the valve nut 210 are separated. No multiple people are required to cooperate. A single person can complete the separation of the valve nut 210 and the valve cone 220 by applying torque through the screwing component 130, which improves the disassembly and assembly efficiency of the valve core 200 and makes the disassembly efficiency of the valve core 200 higher.

[0037] like Figure 2 As shown, in some embodiments, the upper end of the valve nut 210 has a plurality of protrusions 211 spaced apart around the valve nut 210, and the abutment portion 1311 is located between two adjacent protrusions 211. When the screwing assembly 130 rotates, the abutment portion 1311 abuts against the protrusions 211.

[0038] In some embodiments, the upper end of the valve nut 210 has three protrusions 211 spaced apart around the valve nut 210, and the screwing assembly 130 has three abutment portions 1311, which are respectively located in the three intervals formed by the three protrusions 211.

[0039] You can refer to this. Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the screwing assembly 130 includes a force transmission member 131 and a force application member 132. The force transmission member 131 is disposed opposite to the limiting assembly 120. The force transmission member 131 has a clearance hole 131a for the upper valve stem 221 of the valve cone 220, and the end of the force transmission member 131 near the limiting assembly 120 has an abutment portion 1311. The force application member 132 is connected to the end of the force transmission member 131 away from the limiting assembly 120, and drives the force transmission member 131 to rotate.

[0040] The valve nut 210 is threaded onto the upper valve stem 221 of the valve cone 220, with the upper valve stem 221 passing through the valve nut 210. A clearance hole 131a is provided on the force transmission component 131 to prevent the upper valve stem 221 from interfering with the force transmission component 131 and the force application component 132. The clearance hole 131a of the force transmission component 131 is located on the end face of the force transmission component 131 near the tightening assembly 130, i.e. Figure 1 The lower end face of the valve cone 220 has a clearance hole 131a to allow the upper valve stem 221 to pass. When the force transmission component 131 tightens the valve nut 210, the upper valve stem 221 is located inside the clearance hole 131a, meaning the force transmission component 131 is sleeved outside the upper valve stem 221. With this design, the force application component 132 rotates, causing the force transmission component 131 to rotate, which in turn causes the valve nut 210 to rotate, thus enabling the disassembly or installation of the valve nut 210 and the valve cone 220. The force application component 132 can be a commercially available wrench or similar device.

[0041] In some embodiments, the force transmission member 131 has an insertion portion 1312 at one end away from the limiting component 120, and the force application member 132 has a connecting hole 132a, with the insertion portion 1312 located within the connecting hole 132a.

[0042] It should be noted that, to ensure that the force-applying component 132 can drive the force-transmitting component 131 to rotate, the connecting hole 132a should be a non-circular hole, such as a triangle or quadrilateral. The shape of the insertion part 1312 should also be non-circular, such as a triangle or quadrilateral, to ensure that when the force-applying component 132 rotates, the inner wall of the connecting hole 132a of the force-applying component 132 can abut against the outer wall of the insertion part 1312, thereby driving the insertion part 1312 to rotate, and thus driving the force-transmitting component 131 to rotate as a whole. When the insertion part 1312 is inserted into the connecting hole 132a, the force-transmitting component 131 and the force-applying component 132 are connected; when the insertion part 1312 is not inserted into the connecting hole 132a, the force-transmitting component 131 and the force-applying component 132 are separated. With this design, the force transmission component 131 and the force application component 132 can be detachably connected. When the one-way valve core disassembly and assembly tool 100 is not in use, the insertion part 1312 can be pulled out, which separates the force transmission component 131 and the force application component 132, making it convenient to store the one-way valve core disassembly and assembly tool 100.

[0043] In some embodiments, the insertion part 1312 is hexagonal prism-shaped, and the cross-section of the connecting hole 132a is hexagonal.

[0044] In some embodiments, a plurality of abutment portions 1311 are spaced apart along the circumference of the force transmission member 131. The multiple abutment portions 1311 spaced apart along the circumference of the force transmission member 131 can evenly distribute the force applied to the valve cone 220, avoiding localized stress concentration damage to the valve nut 210 caused by single-point force application. Furthermore, the multiple abutment portions 1311 simultaneously contact the valve nut 210, forming multi-point support, effectively preventing the valve nut 210 and the tightening assembly 130 from tilting or slipping during tightening, thus improving the stability and reliability of the disassembly process.

[0045] In some embodiments, the force-applying component 132 is a hydraulic torque wrench, and the one-way valve core disassembly and assembly tool 100 further includes a limiting post 140, which is mounted on the support base 110 and is located on the rotation path of the hydraulic torque wrench.

[0046] Hydraulic torque wrenches, also known as hydraulic torque wrenches or hydraulic wrenches, have various structures, which are well known to those skilled in the art. With this design, the hydraulic torque wrench, after operation, can rest against the limiting post 140. The limiting post 140 limits the hydraulic torque wrench, which drives the force transmission component 131 to rotate, thereby rotating the valve nut 210. This design allows the hydraulic torque wrench to automatically rotate the valve nut 210. During use, the operator only needs to install the valve cone 220 on the limiting component 120, place the force transmission component 131 on the valve nut 210, and then install the hydraulic torque wrench on the force transmission component 131. Then, controlling the operation of the hydraulic torque wrench completes the disassembly and assembly of the valve core 200, helping to reduce the labor intensity of personnel and improve the disassembly efficiency of the valve core 200.

[0047] In some embodiments, the limiting post 140 is provided with a mounting hole 140a for mounting a lifting lug. The mounting hole 140a can be a threaded hole, and the lifting lug can be connected to the limiting post 140 through the mounting hole 140a. The lifting lug can be connected to the hook of a lifting device, etc. This design facilitates the movement of the one-way valve core disassembly and assembly tool 100.

[0048] In some embodiments, two limiting posts 140 are provided, spaced apart, and a hydraulic torque wrench is located between the two limiting posts 140. This design allows the hydraulic torque wrench to abut against one of the limiting posts 140 when rotated clockwise and against the other limiting post 140 when rotated counterclockwise. This allows the hydraulic torque wrench to tighten the valve nut 210 so that the valve nut 210 can be installed on the valve cone 220, and also allows the hydraulic torque wrench to loosen the valve nut 210 so that the valve nut 210 can be removed from the valve cone 220.

[0049] In some embodiments, the limiting component 120 includes a first limiting member 121 and a second limiting member 122. The first limiting member 121 and the second limiting member 122 are disposed opposite to each other and are both connected to the support base 110. The first limiting member 121, the second limiting member 122 and the support base 110 together form a limiting groove, and the guide frame 222 of the valve cone 220 is located in the limiting groove.

[0050] The first limiting member 121 and the second limiting member 122 are arranged vertically, and there is a gap between the first limiting member 121 and the second limiting member 122. The guide frame 222 of the valve cone 220 is located between the first limiting member 121 and the second limiting member 122. The first limiting member 121 and the second limiting member 122 limit the guide frame 222, and the circumferential degree of freedom of the valve cone 220 is restricted, so that when the valve nut 210 rotates, the valve cone 220 cannot rotate around the axial direction, ensuring that the valve cone 220 and the valve nut 210 can be easily disassembled and assembled.

[0051] In some embodiments, the limiting assembly 120 further includes a connector 123, which is disposed opposite to the support base 110 and detachably connected to the first limiting member 121 and the second limiting member 122. The connector 123 is detachably connected to both the first limiting member 121 and the second limiting member. After the connector 123 is connected to the first limiting member 121 and the second limiting member 122, there is a gap between the connector 123 and the support base 110. With this design, the valve cone 220 is limited between the first limiting member 121, the second limiting member 122, the connector 123, and the support base 110. The axial freedom of the guide frame 222 of the valve cone 220 is restricted by the connector 123 and the support base 110, preventing the valve cone 220 from moving axially when tightening the valve nut 210, thus ensuring the stability of the assembly and disassembly process.

[0052] In some embodiments, both the first limiting member 121 and the second limiting member 122 are provided with through holes 120a, and the connecting member 123 passes through the through holes 120a. It should be noted that the connecting member 123 may or may not pass through the through holes 120a. When the connecting member 123 passes through the through holes 120a, the connecting member 123 is connected to the first limiting member 121 and the second limiting member 122; when the connecting member 123 is outside the through holes 120a, the connecting member 123 is not connected to the first limiting member 121 and the second limiting member 122. The design of the through holes 120a facilitates the installation and removal of the connecting member 123.

[0053] In some embodiments, such as Figure 3 As shown, the connector 123 includes a bolt and a nut. The bolt passes through the first limiting member 121 and the second limiting member 122 in sequence and is then threadedly connected to the nut.

[0054] The valve cone 220 has multiple guide frames 222. In some embodiments, multiple limiting components 120 are provided at intervals, so that each guide frame 222 can be limited by the corresponding limiting component 120, thus ensuring the stability of the disassembly and assembly process.

[0055] The working principle of the one-way valve core disassembly and assembly tool 100 of this application is described below:

[0056] When the valve core 200 needs to be disassembled, first remove the nut from the bolt, then pull the bolt out of the through hole 120a, then place each guide bracket 222 of the valve cone 220 of the valve core 200 between the corresponding first limit member 121 and second limit member 122, then insert the bolt into the through hole 120a, then connect the nut to the bolt, then sleeve the force transmission member 131 on the upper valve stem 221 of the valve cone 220, so that the abutment part 1311 at the bottom of the force transmission member 131 is located between two adjacent protrusions 211, then connect the hydraulic torque wrench to the force transmission member 131, then start the hydraulic torque wrench, the hydraulic torque wrench will abut against the limit post 140 and drive the force transmission member 131 to rotate, the abutment part 1311 of the force transmission member 131 drives the valve nut 210 to rotate, thereby removing the valve nut 210 from the valve cone 220.
