[0002] Valves are control components in pipeline fluid delivery systems, used to change the cross-section of the passage and the direction of the medium's flow. They perform functions such as diversion, shutoff, throttling, check valves, diversion, or overflow and pressure relief. Valves used for fluid control come in a wide variety of types and specifications, from the simplest globe valves to valves used in highly complex automatic control systems. Valve nominal diameters range from tiny instrument valves to valves for industrial pipelines with diameters up to 10 meters. Valves require inspection and maintenance after extended use to prevent blockage and damage.

[0003] After searching, the prior art announcement number CN218582383U discloses a valve that is easy to maintain, including an external spliced ​​valve housing, a square connecting pipe, a connecting water pipe and a sealing plug-in plate. The square connecting pipe is threadedly connected to both sides of the external spliced ​​valve housing, the connecting water pipe is fixedly plugged into the square connecting pipe, and the sealing plug-in plate is movably plugged into the square connecting pipe and the connecting water pipe. The utility model makes it possible to plug the sealing plug-in plate into the connecting water pipe to seal the connecting water pipe when the valve is disassembled for maintenance, thereby blocking the water flow for better maintenance. At the same time, it is also convenient to disassemble the external spliced ​​valve housing, and after disassembly, the external spliced ​​valve housing can be disassembled and disassembled for a second time to better maintain the valve, thereby effectively improving the maintenance convenience of the valve that is easy to maintain.

[0004] However, when disassembling the utility model, the hand or elbow of the person may accidentally touch the valve handle and cause it to rotate, resulting in the need to re-confirm the closure of the valve during subsequent installation to prevent the flow of liquid in the valve body. Therefore, a valve that is easy to maintain is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a valve that is easy to maintain and has the advantages of preventing the valve handle from rotating. It solves the problem that the hand or elbow of the person accidentally touches the valve handle and causes it to rotate during disassembly, resulting in the need to reconfirm that the valve is closed during later installation to avoid liquid flow in the valve body.

[0006] To achieve the above object, the present invention provides the following technical solution: a valve that is easy to maintain, comprising a valve body, a side of the valve body being connected to a valve pipe, and an upper side of the valve pipe being provided with a limiting structure;

[0007] The limiting structure includes an internal third spring fixedly connected to the upper sides of the two valve tubes, a slider fixedly connected to one side of the third spring, a connecting rod rotatably sleeved on the upper side of the slider, a ring plate rotatably sleeved on the upper side of the connecting rod, two U-shaped blocks fixedly connected to the upper side of the ring plate, and a clip strip rotatably sleeved on the upper side of the valve tube.

[0008] Furthermore, a disassembly device is provided on one side of the valve tube, and the disassembly device includes a fixed cylinder fixedly connected to the side of the valve tube away from the valve body, two fixed blocks clamped inside the fixed cylinder, a connecting block fixedly connected to the opposite side of the two fixed blocks, two first springs fixedly connected to the opposite side of the two connecting blocks, and a connecting tube fixedly connected to the side of the first spring away from the connecting block.

[0009] Furthermore, a pushing structure is provided inside the fixed cylinder, and the pushing structure includes two connecting rods slidably sleeved inside the fixed cylinder, a clamping plate fixedly connected to one side of the connecting rods, and a roller rotatably sleeved on one side of the connecting rods.

[0010] Furthermore, a limiting assembly is provided on one side opposite to the two fixed cylinders, and the limiting assembly includes a movable shaft rotatably sleeved on one side opposite to the two fixed cylinders and a clamping block sleeved on the outer side of the movable shaft.

[0011] Furthermore, a through hole matching the fixing block is provided inside the fixing cylinder, and a limiting groove matching the fixing block is provided inside the clamping plate.

[0012] Furthermore, a sliding groove matched with the slider is provided inside the upper side of the valve tube, and a limiting groove matched with one end of the clamping strip is provided inside the upper side of the slider.

[0013] Furthermore, the inner wall of the annular plate is sleeved on the outer wall of the upper side of the valve body.

[0014] Furthermore, two second springs are fixedly connected to opposite sides of the two connecting pipes, and a filter is fixedly connected to a side of the second spring away from the connecting pipe.

[0015] Compared with the prior art, the present invention provides a valve that is easy to maintain and has the following beneficial effects:

DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figures 1 to 5In this embodiment, a valve designed for easy maintenance includes a valve body 1, the side of which is connected to a valve tube 14. A position limiting structure is provided on the upper side of the valve tube 14. The position limiting structure includes an internal third spring 18 fixedly connected to the upper sides of the two valve tubes 14, a slider 16 fixedly connected to one side of the third spring 18, a connecting rod 17 rotatably mounted on the upper side of the slider 16, an annular plate 19 rotatably mounted on the upper side of the connecting rod 17, two U-shaped clamping blocks 20 fixedly connected to the upper side of the annular plate 19, and a clamping strip 15 rotatably mounted on the upper side of the valve tube 14.

[0027] Among them, a disassembly device is provided on one side of the valve tube 14, which includes a fixed cylinder 3 fixedly connected to the side of the valve tube 14 away from the valve body 1, two fixed blocks 8 clamped inside the fixed cylinder 3, a connecting block 7 fixedly connected to the opposite side of the two fixed blocks 8, two first springs 6 fixedly connected to the opposite side of the two connecting blocks 7, and a connecting tube 2 fixedly connected to the side of the first spring 6 away from the connecting block 7. A pushing structure is provided inside the fixed cylinder 3, and the pushing structure includes two connecting rods 4 slidingly sleeved inside the fixed cylinder 3, a clamping plate 13 fixedly connected to one side of the connecting rod 4, and a rotating sleeve A roller 5 is connected to one side of the connecting rod 4, and a limiting assembly is provided on the opposite side of the two fixed cylinders 3. The limiting assembly includes a movable shaft 11 rotatably sleeved on the opposite side of the two fixed cylinders 3 and a clamping block 12 sleeved on the outer side of the movable shaft 11. A through hole matching the fixed block 8 is provided inside the fixed cylinder 3, and a limiting clamping groove matching the clamping block 12 is provided inside the clamping plate 13. A sliding groove matching the slider 16 is provided inside the upper side of the valve tube 14, and a limiting groove matching one end of the clamping strip 15 is provided inside the upper side of the slider 16. The inner wall of the annular plate 19 is sleeved on the outer wall of the upper side of the valve body 1.

[0028] Example 2

[0029] See also Figure 1 and Figure 3 On the basis of the first embodiment, the second spring 9 is fixedly connected to the opposite sides of the two connecting pipes 2 , and a filter screen 10 is fixedly connected to the side of the second spring 9 away from the connecting pipe 2 .

[0030] By adopting the above technical solution, the filter screen 10 is squeezed against the surface of the valve tube 14 by the elastic action of the second spring 9, thereby being able to directly filter out solid particles in the water.

[0031] The working principle of the above embodiment is:

[0032] During disassembly, the card block 12 is rotated by the movable shaft 11 and moved out from one side of the card plate 13, and the limit on the card plate 13 is cancelled. After the card plate 13 pushes the roller 5 to the side of the fixed cylinder 3 and rolls on the surface of the connecting block 7, the connecting block 7 moves downward, thereby moving the fixed block 8 out of the fixed cylinder 3 without limiting the fixed cylinder 3. The first spring 6 will also be compressed due to the movement of the connecting block 7. The connecting pipe 2 can be directly moved out of the fixed cylinder 3 to achieve quick disassembly, and then the slider 16 is pressed to move to the side of the third spring 18. The connecting rod 17 is squeezed upward under the movement of the slider 16 to drive the U-shaped card block 20 to be stuck in the inside of the valve handle to prevent the valve handle from rotating. Then the card strip 15 is used to be stuck in the internal limit of the slider 16 to prevent the staff from accidentally touching the valve handle during disassembly.

[0033] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects.
