It is usually installed in the pipeline to block unwanted particles through a specific filter medium to ensure that the quality of the outflowing medium meets the requirements.

[0003] For example, a Chinese patent discloses: a filter-type gate valve that is easy to install and disassemble, with the announcement number CN214789117U. The threaded track is provided to facilitate the user to connect the water pipe to the gate valve housing through the water pipe interface, and the threaded track can enhance the sealing of the connection between the water pipe and the gate valve housing. The gate valve top cover and the gate valve housing can be connected together by the provided fixing bolts, so that the user can remove the gate valve top cover from the gate valve housing during maintenance and replacement, and the connection between the gate valve top cover and the gate valve housing can be sealed by the provided sealing gasket.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: the above device screwed the filter valve into the pipeline through the opened threaded track, but when the filter valve needs to be disassembled, the pipeline connected to one end of the filter valve needs to be removed before the filter valve can be disassembled, resulting in a long downtime for maintenance and increased maintenance and operating costs. Utility Model Content

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

At this time, the clamping block rotates and resets in the slide groove, and the clamping block rotates and resets to release the squeeze and fixation on the connecting pipe. At this time, the sleeve is pushed inward to slide toward one end of the filter valve body. The sleeve slides to place the connecting pipe outside the filter valve body. The sleeves at both ends of the filter valve body are slid inward to pull the filter valve body out. When disassembling the filter valve body, there is no need to remove all the pipes on one end, which shortens the downtime of the equipment during maintenance and replacement, and greatly shortens the maintenance and overhaul time.

[0017] 2. When the filter valve body is installed and placed close to the ground, the second clamp and the first clamp can be sleeved on the outside of the connecting pipe before the filter valve body and the connecting pipe are connected, and the first clamp and the second clamp are installed and fixed by screwing the fixing bolts. At this time, the filter valve body is supported by the base to ensure that the filter valve body is placed stably, so that the filter valve body is not easy to shake or move during operation, thereby avoiding damage or leakage caused by vibration.

[0024] The embodiment of the present application provides an easy-to-disassemble filter valve, which effectively solves the problem that the above-mentioned device screws the filter valve into the pipeline by opening a threaded track. However, when the filter valve needs to be disassembled, the pipeline connected to one end of the filter valve needs to be disassembled before the filter valve can be disassembled, resulting in a long downtime for maintenance, which increases maintenance and operating costs. When the filter valve body needs to be disassembled, replaced and maintained, the threaded barrel is screwed, and the threaded barrel slides outward during rotation. During the sliding process of the threaded barrel, the clamping block is released through the truncated cone groove. At this time, the clamping block rotates and resets in the slide groove, and the clamping block rotates and resets to release the squeezing and fixing of the connecting pipe. At this time, the sleeve is pushed inward to slide toward one end of the filter valve body, and the sliding of the sleeve places the connecting pipe outside the filter valve body. The filter valve body can be pulled out by sliding the sleeves at both ends of the filter valve body inward. When the filter valve body is disassembled, there is no need to completely remove the pipeline at one end, which shortens the downtime of the equipment during maintenance and replacement, and greatly shortens the maintenance and overhaul time.

The overall idea is as follows: a filter valve that is easy to disassemble, including a filter valve body 11, a sleeve 12 is slidably connected to the outer surface of the filter valve body 11, a clamping block 13 is rotatably connected inside the sleeve 12, a threaded barrel 14 is threadedly connected to the outer surface of the sleeve 12, a truncated cone groove 15 is provided inside the threaded barrel 14, the truncated cone groove 15 is fitted with the outer surface of the clamping block 13, a connecting pipe 16 is sleeved inside the truncated cone groove 15, and the connecting pipe 16 is clamped on the outer surface of the clamping block 13, the filter valve body 11 and the connecting pipe 16 are connected to form a channel, and the liquid flowing in the connecting pipe 16 flows through the filter valve body 11 Internally, the liquid is filtered through the filter valve body 11 to remove solid particles and impurities in the liquid, prevent these impurities from entering downstream equipment or systems, and protect pumps, valves and other key equipment from damage or blockage. When the filter valve body 11 needs to be disassembled, replaced and maintained, the threaded barrel 14 is screwed, and the threaded barrel 14 slides outward during rotation. During the sliding process of the threaded barrel 14, the clamping block 13 is released through the truncated cone groove 15. At this time, the clamping block 13 loses its extrusion and becomes loose, and the extrusion and fixation of the connecting pipe 16 are released. At this time, the sleeve 12 is pushed inward to slide toward one end of the filter valve body 11. The sleeve 12 slides to place the connecting pipe 16 outside the filter valve body 11. The sleeves 12 at both ends of the filter valve body 11 are slid inward to pull the filter valve body 11 out. When the filter valve body 11 is disassembled, there is no need to completely remove the pipeline at one end, which shortens the downtime of the equipment during maintenance and replacement, and greatly shortens the maintenance and overhaul time.

[0027] A quick-release mechanism is fixedly connected to the outer surface of the filter valve body 11, and the quick-release mechanism includes a ring 17, which is fixedly connected to the outer surface of the filter valve body 11, and a spring 18 is fixedly connected to the outer surface of the ring 17. The sleeve 12 is sleeved on the outer surface of the spring 18, and a sealing ring 19 is sleeved inside the sleeve 12. The sealing ring 19 is sleeved on the outer surface of the connecting pipe 16. A slide groove 21 is provided inside the sleeve 12, and the clamping block 13 is rotatably connected inside the slide groove 21. When the filter valve body 11 and the connecting pipe 16 are installed, the threaded barrel 14 is sleeved to the outer surface of the connecting pipe 16, and the connecting pipe 16 is extended into the sleeve 12. At this time, the sealing ring 19 is sleeved on the outer surface of the connecting pipe 16 for sealing, and the threaded barrel 14 outside the connecting pipe 16 is screwed to the outside of the sleeve 12. During the rotation of the threaded barrel 14, the clamping block 13 is squeezed to rotate, and the connecting pipe 16 is clamped and fixed by the rotation of the clamping block 13.

[0028] A first clamp 22 is sleeved on the outer surface of the filter valve body 11, and a base 23 is fixedly connected to the lower end of the first clamp 22. A second clamp 24 is movably connected to the outer surface of the first clamp 22. The first clamp 22 and the second clamp 24 are both threadedly connected with fixing bolts 25. When the filter valve body 11 is installed and placed close to the ground, the second clamp 24 and the first clamp 22 can be sleeved on the outside of the connecting pipe 16 before the filter valve body 11 and the connecting pipe 16 are connected. The first clamp 22 and the second clamp 24 are installed and fixed by screwing the fixing bolts 25. At this time, the filter valve body 11 is supported by the base 23 to ensure that the filter valve body 11 is placed stably, so that the filter valve body 11 is not easy to shake or move during operation, thereby avoiding damage or leakage caused by vibration.

[0029] In view of the problems existing in the prior art, the utility model provides a filter valve that is easy to disassemble. When the filter valve body 11 needs to be disassembled, replaced and maintained, the threaded barrel 14 is screwed. The threaded barrel 14 slides outward during rotation. During the sliding process of the threaded barrel 14, the squeezing of the clamping block 13 is released through the truncated cone groove 15. At this time, the clamping block 13 loses its squeezing and becomes loose, and the squeezing and fixing of the connecting pipe 16 are released. At this time, the sleeve 12 is pushed inward to slide toward one end of the filter valve body 11. The sleeve 12 slides to place the connecting pipe 16 outside the filter valve body 11. The sleeves 12 at both ends of the filter valve body 11 are slid inward to pull the filter valve body 11 out. When the filter valve body 11 is disassembled, there is no need to completely remove the pipeline at one end, which shortens the downtime of the equipment during maintenance and replacement, and greatly shortens the maintenance and overhaul time.

[0030] Working principle:

[0031] In the first step, the filter valve body 11 and the connecting pipe 16 are connected to form a channel. The liquid flowing in the connecting pipe 16 flows through the inside of the filter valve body 11, and the liquid is filtered by the filter valve body 11 to remove solid particles and impurities in the liquid, prevent these impurities from entering the downstream equipment or system, and protect pumps, valves and other key equipment from damage or blockage. When the filter valve body 11 needs to be disassembled, replaced and maintained, the threaded barrel 14 is screwed, and the threaded barrel 14 slides outward during the rotation. During the sliding process of the threaded barrel 14, the clamping block 13 is released through the truncated cone groove 15. At this time, the clamping block 13 loses its extrusion and loosens, and the extrusion and fixation of the connecting pipe 16 are released. At this time, the sleeve 12 is pushed inward toward one end of the filter valve body 11, and the sleeve 12 slides The connecting pipe 16 is placed outside the filter valve body 11, and the sleeves 12 at both ends of the filter valve body 11 are slid inward to pull the filter valve body 11 out. When disassembling the filter valve body 11, there is no need to completely remove the pipeline at one end, which shortens the downtime of the equipment during maintenance and replacement, and greatly shortens the maintenance and overhaul time. When installing the filter valve body 11 and the connecting pipe 16, the threaded barrel 14 is sleeved onto the outer surface of the connecting pipe 16, and the connecting pipe 16 is extended into the sleeve 12. At this time, the sealing ring 19 is sleeved on the outer surface of the connecting pipe 16 for sealing, and the threaded barrel 14 outside the connecting pipe 16 is screwed to the outside of the sleeve 12. During the rotation of the threaded barrel 14, the clamping block 13 is squeezed to rotate, and the connecting pipe 16 is clamped and fixed by the rotation of the clamping block 13.

[0032] In the second step, when the filter valve body 11 is installed and placed close to the ground, the second clamp 24 and the first clamp 22 can be sleeved on the outside of the connecting pipe 16 before the filter valve body 11 and the connecting pipe 16 are connected, and the first clamp 22 and the second clamp 24 are installed and fixed by screwing the fixing bolts 25. At this time, the filter valve body 11 is supported by the base 23 to ensure that the filter valve body 11 is placed stably, so that the filter valve body 11 is not easy to shake or move during operation, thereby avoiding damage or leakage caused by vibration.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
