[0038] like Figures 1-9 As shown, this utility model discloses a multi-functional valve wrench that combines multiple functions, including:
[0039] The wrench body 1 has an inwardly recessed groove 2 at one end and a threaded mounting hole 3 through one wall of the groove 2 on one side of the wrench body 1.
[0040] Replacement head, wherein multiple replacement heads are provided, each of the multiple replacement heads includes an operating end and a connecting end. The operating end is used to connect a ball valve / balance valve / filter. The connecting end has a structure adapted to the groove 2. When the connecting end is placed in the groove 2, a first slot 4 that penetrates the connecting end vertically is opened at the position corresponding to the mounting hole 3. The bottom end of the first slot 4 is a flared mouth.
[0041] Spring plunger 5 is disposed in the mounting hole 3 and the first slot 4, and the ball head of the spring plunger 5 is engaged with the flared opening at the front end of the first slot 4.
[0042] The wrench body 1 is designed as a long strip with an arc-shaped long side for easy gripping. The wrench body 1 has a hollow structure to reduce its weight. The material of the wrench body 1 can be selected according to actual needs, and is generally made of metal, such as iron.
[0043] One end of the wrench body 1 is provided with a groove 2 structure for connecting replacement heads. Multiple replacement heads are provided, and each replacement head can be detachably connected and fixed to the wrench body 1 for easy disassembly and assembly, forming a modular structure for replacement. In this embodiment, three types of replacement heads are provided, each having an operating end for adapting to the operating cap of a ball valve, balance valve, and filter, and a connecting end for connecting to the groove 2 of the wrench body 1. An installation hole 3 is provided on the groove 2, and the connecting end can be inserted into the groove 2. When the connecting end is fully inserted into the groove 2, a first slot 4 is provided at the position corresponding to the mounting hole 3. The inner sidewall of the first slot 4 is also threaded. By screwing the spring plunger 5 into the mounting hole 3 and the second slot 10, the ball head of the spring plunger 5 is just stuck at the flared end of the first slot 4. By pulling the connecting head 9 outward, the flared end squeezes the ball head, and the ball head retracts into the body of the spring plunger 5, so the connecting head 9 can be removed for replacement.
[0044] In one specific embodiment, the replacement head includes a ball valve replacement head 6, a balance valve replacement head 7, and a filter replacement head 8.
[0045] The ball valve replacement head 6 includes a first operating end 62 and a first connecting end 61. The first operating end 62 is a structure adapted to the ball valve operating cap, and the first operating end 62 and the first connecting end 61 are integrally formed.
[0046] The first connecting end 61 of the ball valve replacement head 6 is used to connect to the groove 2 of the wrench body 1, and the first operating end 62 is used to connect to the operating cap of the ball valve, so that the ball valve can be operated.
[0047] The balance valve replacement head 7 includes a second operating end 72 and a second connecting end 71. The second operating end 72 is a structure adapted to the balance valve operating cap, and the second operating end 72 and the second connecting end 71 are integrally formed.
[0048] The second connecting end 71 of the aforementioned balance valve replacement head 7 is used to connect to the groove 2 of the wrench body 1, and the second operating end 72 is used to connect to the operating cap of the balance valve, thereby enabling the balance valve to be operated.
[0049] The filter replacement head 8 includes a third operating end 82 and a third connecting end 81. The third connecting end 81 extends toward the side away from the wrench body 1 and is provided with an arc-shaped pressure plate 83. The third operating end 82 is a soft strip structure. A collar 84 is hinged on the pressure plate 83. One end of the third operating end 82 is fixedly connected to the collar 84, and the length of the third operating end 82 is greater than the circumference of the filter operating cap. A protrusion 85 is provided on the side of the third operating end 82 opposite to the pressure plate 83. The protrusion 85 is adapted to the anti-slip texture on the periphery of the filter operating cap.
[0050] The third connecting end 81 of the filter replacement head 8 is used to connect to the groove 2 of the wrench body 1, and the second operating end 72 is used to connect to the operating cap of the filter, so that the filter can be operated.
[0051] The connection between the third operating end 82 and the filter operating cap is specifically as follows: an arc-shaped pressure plate 83 extends from the third connecting end 81 away from the wrench body 1. A through hole for hinged mounting of a collar 84 is provided in the middle of the pressure plate 83. The collar 84 can rotate around the through hole. The third operating end 82 is a soft, strip-shaped structure, which can be made of rubber. One end of the third operating end 82 passes through the collar 84 for a distance and then folds back to adhere to the third operating end 82. It is fixed by adhesive or heat fusion at the fitting position. The other end of the third operating end 82 can pass through the collar 84, forming a ring structure that fits onto the filter operating cap. The pressure plate 83 then presses the third operating end 82 onto the operating cap. In the opposite direction from the third operating end 82 passing through the collar 84, the pressure plate 83 acts as a fulcrum, the collar 84 as a resistance point, and the wrench body 1 as a power point, forming a lever structure to drive the operating cap to rotate.
[0052] The protrusion 85 on the inner side of the third operating end 82 can rub against the anti-slip texture on the periphery of the operating cap to prevent the third operating end 82 from rotating on its own.
[0053] Anti-slip textures are provided on the other side of the third operating end 82 and the outer arc side of the pressure plate 83.
[0054] The anti-slip texture on the outer side of the third operating end 82 and on the pressure plate 83 can prevent the pressure plate 83 from sliding during the rotation of the wrench, thus ensuring the stability of the fulcrum.
[0055] It should be noted that the ball valve replacement head 6, the balance valve replacement head 7, and the filter replacement head 8 mentioned above can be set to different sizes to adapt to different models of valves.
[0056] In addition, the connector of the replacement head can be set to a size compatible with commercially available torque wrenches, and can also be connected to a torque wrench to measure the torque required to open the valve.
[0057] In some other embodiments, the other end of the wrench body 1 is provided with a connector 9, the shape of which is adapted to the shape of the groove 2, and a second slot 10 corresponding to the mounting hole 3 is provided on the connector 9.
[0058] By setting the other end of the wrench body 1 as a connector 9 that is compatible with the groove 2, and opening a slot on the connector 9, two or more wrenches can be connected end to end to the groove 2 through the connector 9 and fixed by the spring plunger 5, thereby extending the wrench and setting it according to the actual operating environment.
