The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

As shown in fig. 1 and 2, the present VCR valve includes a valve body 210 and a valve knob 220, the valve knob 220 is used for an operator to adjust a pipeline provided with the valve, the valve body 210 is used for the operator to disassemble and assemble, and a plane for matching with the wrench 100 is provided on the valve body 210.

The inventor of the present application found that in the process of disassembling and assembling the valve by using the existing wrench 100, the rotation plane of the wrench 100 and the valve body 210 are located at the same height, and when the valve is installed densely, interference occurs between the wrench 100 and the adjacent valve in the process of rotation, so that the valve is inconvenient to disassemble and assemble. Based on this, the inventor of the present application provides a wrench 100, in which the rotation plane of the wrench 100 is higher than the valve body 210 and the valve knob 220 in the process of rotating the wrench 100 to disassemble the valve, so as to avoid interference between the wrench 100 and the adjacent valve, and the valve can be conveniently disassembled in a scene of dense installation of the valve.

In one embodiment of the present application, as shown in fig. 3, the wrench 100 includes a first moment arm 110 and a second moment arm 120, the first moment arm 110 and the second moment arm 120 forming a relief area 140 for the relief valve knob 220 and a clamping area 130 for clamping the valve body 210. Specifically, as shown in fig. 4, the first moment arm 110 includes a first section 111, a second section 112, and a third section 113 that are sequentially connected; as shown in fig. 5, the second moment arm 120 includes a fourth segment 121, a fifth segment 122, and a sixth segment 123 connected in sequence, wherein the second segment 112 and the fifth segment 122 form an avoidance region 140, and the third segment 113 and the sixth segment 123 form a clamping region 130. That is, the first moment arm 110 and the fourth moment arm are located on one side of the avoidance region 140, and the clamping region 130 is located on the opposite side of the avoidance region 140.

It should be understood by those skilled in the art that the valve body 210 of the valve is directly connected to the pipe. In the process of disassembling and assembling the valve by using the wrench 100 provided in the foregoing embodiment, the clamping area 130 may be used to clamp the valve body 210, so that the avoidance area 140 surrounds the valve knob 220 on the inner side, and then the first section 111 and the fourth section 121 are located on one side of the valve knob 220 away from the valve body 210, that is, the first section 111 and the fourth section 121 are located above the valve, after the valve body 210 is clamped according to the foregoing clamping manner, in the process of disassembling and assembling the valve by rotating the wrench 100, the first section 111 and the fourth section 121 rotate above the valve, so that interference between the first section 111 and the fourth section 121 and adjacent valves does not occur in the rotating process, and the valve is convenient to be disassembled and assembled by an operator.

Thus, the wrench 100 provided herein can be used in situations where the valve is installed more densely. In the art, even though the valves are densely installed, there should be a gap between the valve bodies 210 in adjacent two valves. That is, during rotation of the wrench 100, there is a gap between adjacent valves for the second and fifth sections 112, 122 to pass through.

Because there are valves with multiple specifications in the prior art, in order to be able to adapt to valves with different specifications, in some embodiments of the present application, the first force arm 110 is slidably connected to the second force arm 120, and the width of the avoidance area 140 and the clamping area 130 is changed by the relative movement of the first force arm 110 and the second force arm 120, so as to adapt to the sizes of the valves with different specifications; wherein the width is the dimension of the first arm 110 and the second arm 120 in the direction of the relative motion, such as the dimension indicated by arrow a in fig. 3. Further, it may be that the first segment 111 is slidably coupled to the fourth segment 121 to provide a sliding connection between the first force arm 110 and the second force arm 120.

To achieve a sliding connection between the first section 111 and the fourth section 121, in some embodiments, it may be that the fourth section 121 is sleeved outside the first section 111. Of course, in other embodiments, the first section 111 may be sleeved outside the fourth section 121. Alternatively, in some embodiments, a chute may be provided on the first section 111, and the fourth section 121 slides along the chute; alternatively, the fourth section 121 is provided with a chute, and the first section 111 slides along the chute.

In the case that the fourth segment 121 is sleeved with the first segment 111, in order to avoid relative rotation between the fourth segment 121 and the first segment 111, in some embodiments, the contact surface between the fourth segment 121 and the first segment 111 includes a plane, so as to avoid relative rotation between the first segment 111 and the fourth segment 121 about the relative movement direction as an axial direction, further avoid the situation that the third segment 113 and the sixth segment 123 are staggered from each other, and cannot clamp the valve body 210, thereby reducing the time for adjusting the wrench 100.

Further, when the fourth section 121 is sleeved outside the first section 111, the outer contour of the cross section of the first section 111 may be rectangular, and the inner contour of the cross section of the fourth section 121 may be rectangular; the cross sections of the first section 111 and the fourth section 121 are cross sections perpendicular to the relative sliding direction. Of course, the outer contour of the cross section of the first section 111 and the inner contour of the cross section of the fourth section 121 may also be elliptical, so long as the cross section contour of the contact surface of the first section 111 and the fourth section 121 is not circular, the relative rotation of the first section 111 and the fourth section 121 can be avoided.

In order to facilitate the relative sliding of the first section 111 and the fourth section 121, a grip 124 may be provided on either the first section 111 or the fourth section 121. For example, in some embodiments, the fourth section 121 is sleeved outside the first section 111, the grip 124 is disposed on the fourth section 121, and the operator can conveniently slide the fourth section 121 relative to the first section 111 through the grip 124. Further, the free end of grip 124 extends away from grip region 130. Where the free end of grip 124 is the end that is not connected to either first segment 111 or fourth segment 121, illustratively, when grip 124 is connected to fourth segment 121, the free end of grip 124 is the end that is not connected to fourth segment 121.

Because the free end of the grip 124 extends away from the clamping area 130, when the wrench 100 provided in the above embodiment is used, the valve can be disassembled and assembled by adopting the manner that the avoiding area 140 is located above and the clamping area 130 is located below, and in this use state (as shown in fig. 6), the grip 124 is in a vertical state, so that an operator can conveniently slide the fourth section 121 relative to the first section 111 to change the width of the clamping area 130 during the process of clamping the valve body 210, and can also conveniently exert a better force by gripping the grip 124 during the process of disassembling and assembling the valve, thereby being more convenient for the operator to operate.

The spanner 100 provided in this embodiment of the present application realizes the clamping of the valve body 210 through the first force arm 110 and the second force arm 120, and in the process of disassembling the valve, the first force arm 110 and the second force arm 120 receive the reaction force from the valve body 210, so, in order to avoid the problem that the clamping effect on the valve body 210 cannot be achieved due to the relative sliding of the first force arm 110 and the second force arm 120 after receiving the reaction force in the process of disassembling the valve, in some embodiments, the fixing knob 150 for fixing the first section 111 and the fourth section 121 is further provided.

For example, in the embodiment in which the fourth section 121 is sleeved outside the first section 111, the fixing knob 150 is disposed on the fourth section 121, so that the operator can operate the fixing knob 150. In some embodiments, the fixing knob 150 is provided with external threads, the fourth section 121 is provided with internal threads that cooperate with the fixing knob 150, and the fixing knob 150 can be abutted against the first section 111 after being screwed, so that relative movement between the first section 111 and the fourth section 121 is not possible. Specifically, a through hole is provided in the fourth section 121, and an internal thread matching the fixing knob 150 is provided in the through hole, so that the fixing knob 150 can be abutted against the first section 111 after being screwed.

In the wrench 100 provided in the present application, the installation position of the fixing knob 150 is not particularly limited, and in some preferred embodiments, the fixing knob 150 is installed on the side of the fourth segment 121 facing away from the avoidance area 140. As shown in fig. 3 and 5, the fourth section 121 is a square tubular structure, and the fixing knob 150 is disposed on the upper side of the fourth section 121.

In other embodiments, other connection means may be used to secure the first segment 111 and the fourth segment 121 using the securing knob 150. Taking the fourth section 121 as an example of sleeving the outer side of the first section 111, threaded holes can be formed in the first section 111 according to the sizes of the valve bodies 210 with different specifications at certain intervals, only through holes for the fixing knob 150 to pass through are required to be formed in the first section 111, the fixing knob 150 can fix the first section 111 and the fourth section 121 when being matched with the threaded holes at different positions on the first section 111, and the clamping areas 130 defined between the first force arm 110 and the second force arm 120 are matched with the valve bodies 210 with different specifications.

According to the wrench 100 provided in the above embodiment, the width of the clamping area 130 is adjusted to adapt to the valve body 210 with different specifications, so that damage to the valve body 210 caused by a gap between the clamping area 130 and the valve body 210 in the process of assembling and disassembling the valve is avoided.

In some embodiments of the present application, in order to enable the wrench 100 to effectively clamp the valve body 210, the wrench 100 is prevented from easily falling off from the valve body 210 after clamping the valve body 210, and the clamping area 130 is an area between two planes, that is, after the wrench 100 clamps the valve body 210, the wrench 100 is difficult to separate from the valve body 210 due to planar contact between the wrench 100 and the valve body 210. Specifically, in some embodiments, the end surfaces of the third segment 113 and the sixth segment 123 are all planar and parallel to each other, the area between the end surfaces of the third segment 113 and the sixth segment 123 is the clamping area 130, and the size of the clamping area 130 can be adjusted by the relative movement between the first segment 111 and the fourth segment 121.
