Description

Technical Field

[0001] This utility model relates to the field of valve maintenance tools, and in particular to a multi-functional wrench and a flat-type passage valve. Background Technology

[0002] Traditional valves are usually manually controlled to open and close. One end of the valve shaft extends out of the valve body and connects to the handle. When disassembling the valve shaft, the handle is turned to rotate the valve shaft. However, after the handle is rotated to a certain angle, it becomes difficult to rotate it further and is not easy to operate.

[0003] To address the above issues, the prior art, including utility model CN219987453U, discloses a valve wrench. One end of the handle has a mounting ring, and the inner side of the mounting ring is movably connected to a mounting shaft. Several force shafts are movably connected to the end of the mounting shaft. In use, the force shafts are inserted into the valve's insertion hole, and the handle is reciprocated along the axis of the mounting ring to control the valve's rotation. This reduces the range of handle rotation, making it suitable for use in confined spaces and improving the efficiency of valve rotation in such environments.

[0004] However, the above patents only apply to valves where only one end of the valve shaft extends out of the valve body. They cannot remove valve shafts that extend out of the valve body at both ends. Furthermore, for electrically controlled valves, the electric actuator must be disassembled before the valve shaft can be removed, which is complicated and inefficient. Utility Model Content

[0005] In view of this, the present invention proposes a multi-functional wrench and a flat-type passage valve to solve the technical problems mentioned in the background art, which are only applicable to valves with only one end of the valve shaft extending out of the valve body, and cannot remove valve shafts with both ends extending out of the valve body. Furthermore, for electrically controlled valves, it is necessary to disassemble the electric actuator in order to disassemble the valve shaft, which is complicated in operation and has low maintenance efficiency.

[0006] The technical solution of this utility model is implemented as follows: In a first aspect, this utility model provides a multi-functional wrench for disassembling and assembling valve heads on valve shafts. The multi-functional wrench includes a sleeve and a handle, wherein: The sleeve is provided with a blind hole along the axial direction. The blind hole is used to fit onto the valve head and there is no relative rotation between the sleeve and the valve head. The sleeve and the valve head are detachably connected. The handle is connected to the sleeve and is perpendicular to the axis of the sleeve.

[0007] In some optional embodiments, preferably, a connecting bolt is also included, wherein the sleeve has a through hole along the axial direction, the valve head has a connecting hole, and the connecting bolt passes through the through hole and connects to the connecting hole.

[0008] In some alternative embodiments, preferably, the blind hole includes a socket portion and an anti-rotation portion, the socket portion being part of a whole circle, and the anti-rotation portion filling the gap in the socket portion on the whole circle.

[0009] In some alternative embodiments, preferably, the sleeve has an abutment surface at the bottom of the blind hole.

[0010] In some alternative embodiments, preferably, a reinforcing component is provided between the contact surface and the inner wall of the blind hole.

[0011] In some alternative embodiments, preferably, the reinforcing component includes transverse reinforcing ribs and longitudinal reinforcing ribs located between the contact surface and the inner wall of the blind hole, the transverse reinforcing ribs and the longitudinal reinforcing ribs being arranged alternately and perpendicularly.

[0012] In some alternative embodiments, preferably, the reinforcing component further includes an annular rib located outside the contact surface and connected to the transverse reinforcing rib and the longitudinal reinforcing rib, respectively.

[0013] In some alternative embodiments, preferably, the longitudinal reinforcing rib is broken into two parts by the annular rib, and the annular rib is provided with a thickened portion, the two ends of which are respectively connected to the two parts broken by the longitudinal reinforcing rib.

[0014] In some alternative implementations, preferably, the outer edge of the blind hole is provided with a chamfer for guidance.

[0015] Secondly, this utility model provides a flat passage valve, which is disassembled and assembled using a multi-functional wrench as described in the first aspect. The flat passage valve includes a valve body, a valve shaft, and a valve head. The valve shaft is rotatably mounted on the valve body, and the valve head is threadedly connected to the valve shaft. The valve head is used to insert into the blind hole and is detachably connected to the sleeve.

[0016] The multi-functional wrench of this invention has the following advantages over the prior art: (1) A blind hole is provided along the axial direction through the sleeve. The blind hole is used to fit on the valve head and the sleeve is detachably connected to the valve head. By turning the handle, the valve head can be disassembled and assembled on the valve shaft, and then the valve shaft can be removed. For electrically controlled valves, the valve shaft can be removed by disassembling the valve head at the end of the valve shaft away from the electric drive. The operation is simple and can improve maintenance efficiency. (2) The sleeve is provided with a through hole along the axial direction, and the valve head is provided with a connecting hole. The connecting bolt passes through the through hole and connects to the connecting hole, so that the sleeve and the valve head can be detachably connected, so that the sleeve will not fall off after being put on the valve head, thus improving the convenience of operation. (3) Since the sleeve is part of the whole circle, the anti-rotation part fills the gap of the sleeve on the whole circle. After the blind hole is sleeved on the valve head, the sleeve will not rotate relative to the valve head when it rotates, thus improving the reliability of the device. (4) The sleeve has an abutting surface at the bottom of the blind hole, and the abutting surface abuts and limits the valve head end face, so that it is easy to know that the sleeve is in place, and it can be subjected to force together with the inner wall of the blind hole when rotating, thereby improving the reliability of the device. (5) By providing a reinforcing component between the contact surface and the inner wall of the blind hole, the contact surface and the inner wall of the blind hole are reinforced, thereby improving the strength of the device and thus improving the stability and reliability of the device.

Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1-4 As shown, in a first aspect embodiment of the present invention, a multi-functional wrench is provided for disassembling and assembling a valve head 100 on a valve shaft 200. The valve head 100 is provided with a flat square 120, and the valve head 100 is threadedly connected to the valve shaft 200. The multi-functional wrench includes a sleeve 1 and a handle 2, wherein: The sleeve 1 is provided with a blind hole 11 along the axial direction. The blind hole 11 is used to fit onto the valve head 100, and there is no relative rotation between the sleeve 1 and the valve head 100. The sleeve 1 and the valve head 100 are detachably connected. The shape of the blind hole 11 is adapted to the valve head 100, so that after the blind hole 11 is fitted onto the valve head 100, it can drive the valve head 100 to rotate together. The handle 2 is connected to the sleeve 1 and is perpendicular to the axis of the sleeve 1. The handle 2 can be connected to the end of the sleeve 1 away from the blind hole 11, and the bottom end of the handle 2 is higher than the end of the sleeve 1 with the blind hole 11, so that it will not interfere with rotation. The handle 2 and the sleeve 1 can be integrally formed, which simplifies manufacturing and improves load-bearing capacity. This angle setting of the handle 2 facilitates operation in a small vertical space, improving operational convenience.

[0022] The multi-functional wrench proposed in this embodiment has a blind hole 11 along the axial direction of the sleeve 1. The blind hole 11 is used to fit onto the valve head 100, and the sleeve 1 is detachably connected to the valve head 100. By rotating the handle 2, the valve head 100 can be installed and removed from the valve shaft 200, and then the valve shaft 200 can be removed. For electrically controlled valves, the valve shaft 200 can be removed simply by removing the valve head 100 at the end of the valve shaft 200 away from the electric actuator. The operation is simple and can improve maintenance efficiency.

[0023] In some embodiments, when disassembling or assembling the valve head 100 located at the bottom of the valve body 300, the sleeve 1 is fitted onto the valve head 100. During rotation, the sleeve 1 is prone to detaching from the valve head 100 under the influence of gravity. To solve this problem, the multi-functional wrench further includes a connecting bolt. The sleeve 1 has a through hole 12 along the axial direction, and the valve head 100 has a connecting hole 110. The connecting bolt passes through the through hole 12 and connects to the connecting hole 110. By connecting the sleeve 1 to the valve head 100 through the through hole 12, a detachable connection is achieved, ensuring that the sleeve 1 will not fall off after being fitted onto the valve head 100, improving operational convenience and disassembly / assembly efficiency.

[0024] In some embodiments, the blind hole 11 includes a sleeve portion 111 and an anti-rotation portion 112. The sleeve portion 111 is part of a complete circle, and the anti-rotation portion 112 fills the gap in the sleeve portion 111 on the complete circle. The sleeve portion 111 has two gaps, and the anti-rotation portion 112 and the sleeve portion 111 form a flat rectangular cross-section. Through the design of the anti-rotation portion 112, after the blind hole 11 is fitted onto the valve head 100, the sleeve 1 will not rotate relative to the valve head 100 when it rotates, thus improving the reliability of the device.

[0025] In some embodiments, the sleeve 1 has an abutment surface 13 at the bottom of the blind hole 11, and the through hole 12 is located on the abutment surface 13. By abutting and limiting the movement of the abutment surface 13 against the end face of the valve head 100, it is easy to know that the sleeve 1 is fitted in place, and it can be subjected to force together with the inner wall of the blind hole 11 when rotating, thereby improving the reliability of the device.

[0026] In some embodiments, a reinforcing component 3 is provided between the contact surface 13 and the inner wall of the blind hole 11. By reinforcing the contact surface 13 and the inner wall of the blind hole 11 with the reinforcing component 3, the strength of the device is improved, thereby improving the stability and reliability of the device.

[0027] In some further embodiments, the reinforcing component 3 includes a transverse reinforcing rib 31 and a longitudinal reinforcing rib 32 located between the contact surface 13 and the inner wall of the blind hole 11, the transverse reinforcing rib 31 and the longitudinal reinforcing rib 32 being arranged alternately and perpendicularly. The arrangement of the transverse reinforcing rib 31 and the longitudinal reinforcing rib 32 connects and strengthens the contact surface 13 and the inner wall of the blind hole 11, allowing them to share the load, thus increasing strength and improving stability and reliability.

[0028] In some embodiments, the reinforcing component 3 further includes annular ribs 33, which are located outside the contact surface 13 and connected to the transverse reinforcing ribs 31 and the longitudinal reinforcing ribs 32, respectively. The annular ribs 33 strengthen the outer edge of the contact surface 13, increasing its strength. This, in turn, improves the load-bearing capacity and reliability of the device after the through hole 12 is connected using connecting bolts.

[0029] In some embodiments, the longitudinal reinforcing rib 32 is broken into two parts by the annular rib 33. The annular rib 33 is provided with a thickened portion 331, and the two ends of the thickened portion 331 are respectively connected to the two broken parts of the longitudinal reinforcing rib 32. The design of the thickened portion 331 improves the strength of the annular rib 33, reduces the possibility of tearing at the connection point with the longitudinal reinforcing rib 32, and improves the reliability of the device.

[0030] In some further embodiments, the thickened portion 331 may be provided with a weight reduction hole 3311. The design of the weight reduction hole 3311 can make the structure lighter and easier to operate.

[0031] In some embodiments, the outer edge of the blind hole 11 is provided with a chamfer 113 for guidance. By providing the chamfer 113, the blind hole 11 can be guided during the process of fitting onto the valve head 100, improving convenience and thus increasing the efficiency of disassembly and assembly.

[0032] The working principle of the multi-functional wrench in this embodiment of the utility model is as follows: the sleeve 1 is fitted onto the valve head 100, the connecting bolt passes through the through hole 12 and connects to the connecting hole 110. The design of the anti-rotation part 112 prevents the sleeve 1 from rotating relative to the valve head 100 when it rotates. By rotating the handle 2, the valve head 100 can be disassembled and assembled on the valve shaft 200, and then the valve shaft 200 can be removed.

[0033] Based on the same concept, the second aspect of the present invention, combined with... Figures 5-7 As shown, a flat passage valve is provided, which is disassembled and assembled using a multi-functional wrench as described in the first aspect embodiment. The flat passage valve includes a valve body 300, a valve shaft 200, and a valve head 100. The valve shaft 200 is rotatably mounted on the valve body 300. The valve head 100 is threadedly connected to the valve shaft 200. The valve head 100 is used to insert into the blind hole 11 and is detachably connected to the sleeve 1.

[0034] The flat-type passage valve proposed in this embodiment allows the valve head 100 to be mounted and dismounted from the valve shaft 200 using a multi-functional wrench. Then, the valve shaft 200 can be removed. For electrically controlled valves, the valve shaft 200 can be removed simply by disassembling the valve head 100 at the end of the valve shaft 200 away from the electric actuator. The operation is simple and can improve maintenance efficiency.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
