Description

[Technical field] The invention relates to the technical field of valve auxiliary tools, and in particular to a universal valve key. [Background technology] As a key component in the pipeline system, valves are responsible for controlling the flow, direction, pressure and temperature of fluid media. However, valves come in a variety of sizes and types, so traditional valve keys are often only suitable for specific types of valves, which brings inconvenience to practical applications.

[0003] During emergency repairs, maintenance personnel usually need to carry multiple valve keys of different sizes and types to deal with various valve failures. This not only increases their carrying burden, but may also lead to the wrong key being brought in an emergency, thus delaying the repair time.

[0004] In addition, when multiple valves need to be repaired at the same time, maintenance personnel not only have to carry multiple heavy valve keys, but also spend time looking for the required keys. This will cause a great consumption of their physical strength, especially in on-site maintenance that requires long working hours. [Summary of the invention] The purpose of the present invention is to provide a universal valve key to solve the problem that the current traditional valve keys can only be applied to specific types of valves.

[0006] The present invention is achieved by the following technical solutions: A universal valve key comprises a body and a key handle connected to the body, wherein the body comprises a key head for matching with a valve and a fixing structure for fixing and accommodating the key head, and the key head moves up and down relative to the fixing structure.

[0007] As described above, the universal valve key, the key head includes a plurality of movable rods for matching with the valve and moving up and down relative to the fixed structure.

[0008] As described above, in the universal valve key, the movable rod comprises a first rod portion that matches the valve and provides a supporting force, and a second rod portion that is connected to the first rod portion.

[0009] As for the universal valve key as described above, the fixing structure includes a first fixing block for accommodating a plurality of the first rods, a second fixing block for accommodating a plurality of the second rods, and a third fixing block for providing a movable space.

[0010] As for the universal valve key as described above, a first space for accommodating a plurality of the first rods is provided in the first fixing block, and the plurality of the first rods move up and down relative to the first space.

[0011] As for the universal valve key as described above, a plurality of positioning posts for positioning the first rod portion are disposed in the first fixing block.

[0012] As described above, in the universal valve key, a plurality of second accommodating holes matching the second rod portions are provided in the second fixing block, and each second rod portion moves up and down relative to each second accommodating hole.

[0013] As described above, in the universal valve key, a second space for accommodating a plurality of the second rods is provided in the third fixing block, and the plurality of the second rods move up and down relative to the second space.

[0014] As described above, the universal valve key, the second rod portion is provided with a clamping block for clamping with the second accommodating hole.

[0015] As for the universal valve key as described above, the first rod portion is in the shape of a square column, and the second rod portion is in the shape of a round column.

[0016] Compared with the prior art, the present invention has the following advantages: First, the key head of the main body is designed to be movable up and down relative to the fixed structure, so that the valve key can flexibly adapt to valves of different types and sizes, which improves the versatility of the valve key, thereby greatly improving work efficiency and operational convenience. Second, the key head is composed of multiple movable rods, which can cooperate with the fixed structure. According to the type and size of the valve, the movable rods can move freely and combine into corresponding shapes to realize the unlocking or locking function of the valve.

[Specific implementation method] Figure 1-7 A universal valve key is shown, comprising a body 1 and a key handle 2 connected to the body 1 , wherein the body 1 comprises a key head 3 for matching with a valve and a fixing structure 4 for fixing and accommodating the key head 3 , and the key head 3 moves up and down relative to the fixing structure 4 .

[0021] In this embodiment, the key head of the main body moves up and down relative to the fixed structure, so that the operator can easily adjust the position of the key head by operating the key handle as needed. This allows the valve key to flexibly adapt to valves of different types and sizes, improves the versatility of the valve key, and thus greatly improves work efficiency and operational convenience.

[0022] Furthermore, the key head 3 includes a plurality of movable rods 31 for matching with the valve and moving up and down relative to the fixed structure 4 .

[0023] In this embodiment, through the design of closely arranging multiple movable rods in a fixed structure, the key head can move up and down relative to the fixed structure through the movable rods according to the type and size of the valve, and then freely combine to form a corresponding shape to achieve the unlocking or locking function of the valve. Specifically, the movable rods can be freely combined to form corresponding shapes through linear arrangement or staggered arrangement according to the type and size of the valve to meet the unlocking or locking requirements of different valves. Secondly, each movable rod can be adjusted independently to ensure that the key head can accurately adapt to the shape and size of different valves. In addition, multiple movable rods can make multi-point contact with the valve, which can disperse the pressure during operation, increase friction, and thus improve operational stability and reduce the occurrence of slipping or misalignment. At the same time, the multi-point contact design effectively reduces the wear between the key head and the valve by reducing local pressure and increasing the contact area, thereby extending the service life of the valve key.

[0024] Furthermore, the movable rod 31 includes a first rod portion 311 that matches the valve and provides a supporting force, and a second rod portion 312 connected to the first rod portion 311 .

[0025] In this embodiment, the first rod portion is in direct contact with the valve and provides a stable main supporting force to ensure close contact between the key head and the valve. The second rod portion allows the movable rod to flexibly move up and down relative to the fixed structure. At the same time, an auxiliary supporting force is provided to the first rod portion, so that the key head can move up and down flexibly, thereby enhancing the structural stability of the entire movable rod and allowing the movable rod to maintain close contact with the valve when moving up and down.

[0026] Specifically, the first rod portion 311 may be in the shape of a square column, and the second rod portion 312 may be in the shape of a round column.

[0027] Furthermore, the fixing structure 4 includes a first fixing block 41 for accommodating a plurality of the first rod portions 311 , a second fixing block 42 for accommodating a plurality of the second rod portions 312 , and a third fixing block 43 for providing a movable space.

[0028] In this embodiment, the first fixing block, the second fixing block and the third fixing block are tightly connected to the first rod portion to form a stable overall frame. The first fixing block and the second fixing block provide reliable support and fixation for the first rod portion and the second rod portion respectively. At the same time, the third fixing block provides the second rod portion with movement space, thereby providing a solid foundation for flexible operation of the valve key and improving the overall operational stability.

[0029] In addition, the first fixing block, the second fixing block and the third fixing block may be connected by welding or bolts.

[0030] In specific use, when the first rods 311 of the multiple movable rods 31 of the key head 3 come into contact with the valve, the first rods 311 will drive the second rods 312 to freely move up and down in the fixed structure 4 according to the type and size of the valve, and combine to form a shape corresponding to the valve in the first fixed block 41. At this time, the multiple first rods 311 matching the valve transmit pressure to the valve through their contact surfaces, and the operator applies operating force through the key handle 2 to realize the unlocking or locking operation of the valve.

[0031] Furthermore, the fixing structure 4 includes a fourth fixing block 44 for connecting to the key handle 2, and the key handle 2 is provided with a connecting block 21 for connecting to the fourth fixing block 44. The connecting block 21 and the fourth fixing block can be connected by welding or bolts.

[0032] Furthermore, a first space 411 for accommodating a plurality of first rod portions 311 is defined in the first fixing block 41 , and the plurality of first rod portions 311 can move up and down relative to the first space 411 .

[0033] Furthermore, a plurality of positioning posts 412 for positioning the first rod portion 311 are disposed in the first fixing block 41 .

[0034] Specifically, the first fixing block 41 is provided with four positioning columns 412, which are symmetrically arranged in the first space and respectively located at four corners to provide uniform positioning and support. The positioning columns 412 are nearly semi-cylindrical to match the circular or square cross-section of the first rod portion to provide uniform contact area and stable support.

[0035] In this embodiment, the positioning column is used to provide uniform and reliable positioning and support for the first rod portion, thereby achieving close fit between multiple first rod portions, ensuring the stability and accuracy of the first rod portion during up and down movement in the first space, reducing the offset and shaking of the first rod portion, and ensuring close contact between the first rod portion and the valve.

[0036] Furthermore, a plurality of second receiving holes 421 matching the second rod portions 312 are formed in the second fixing block 42 , and each of the second rod portions 312 is movable up and down relative to each of the second receiving holes 421 .

[0037] In this embodiment, through the design of the second rod portion and the second accommodating hole, each movable rod can be adjusted independently, thereby ensuring that the key head can accurately adapt to the shapes and sizes of different valves.

[0038] Furthermore, a second space 431 for accommodating a plurality of second rod portions 312 is defined in the third fixing block 43 , and the plurality of second rod portions 312 can move up and down relative to the second space 431 .

[0039] Furthermore, a clamping block 313 for clamping with the second accommodating hole 421 is provided on the second rod portion 312 .

[0040] Specifically, the shape of the clamping block 313 may be cylindrical or rectangular, and its shape and size are larger than the shape and size of the second accommodating hole 421 .

[0041] In this embodiment, the design of the clamping block allows the second rod to move freely up and down in the second space to a limited extent, while preventing the movable rod from falling off or loosening. In addition, in order to increase the friction between the second rod and the second receiving hole, the surface of the second rod can be set as a threaded surface.

[0042] When the present invention is specifically used: When the first rods 311 of the multiple movable rods 31 of the key head 3 come into contact with the valve, the multiple movable rods 31 will freely move up and down in the fixed structure 4 according to the type and size of the valve, and combine to form a corresponding shape. At this time, the multiple first rods 311 matching the valve transmit pressure to the valve through their contact surfaces, and the operator applies operating force through the key handle 2 to realize the unlocking or locking operation of the valve.

[0043] The universal valve key of the present invention is designed so that the key head of the body can move up and down relative to the fixed structure, and the movable rod can move up and down inside the fixed structure, so that the movable rod can be freely combined to form a corresponding shape according to the type and size of the valve, thereby realizing the unlocking or locking function of the valve, which improves the versatility of the valve key, improves the work efficiency and operating convenience of the maintenance personnel, and solves the problem that the current traditional valve key can only be applied to specific types of valves.
