It has a mouth-shaped structure and adopts a double-layer filtration design to improve the filtration efficiency and ensure the operation safety of the system.

[0003] The mouth-shaped filter valve usually relies on installing two filter elements to improve the filtration efficiency. However, the existing installation methods of the filter elements are usually to install the filter elements by screwing or to install them by relying on screwing bolts. Screwing operations in a narrow space are relatively cumbersome, resulting in time-consuming disassembly and maintenance and being not conducive to quickly replacing the filter elements. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a double-layer gas filter valve in a mouth shape, which solves the technical problems that the mouth-shaped filter valve usually relies on installing two filter elements to improve the filtration efficiency, but the existing installation methods of the filter elements are usually to install the filter elements by screwing or to install them by relying on screwing bolts. Screwing operations in a narrow space are relatively cumbersome, resulting in time-consuming disassembly and maintenance and being not conducive to quickly replacing the filter elements.

[0006] (2) Technical Solutions

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0008] A double-layer gas filter valve in a mouth shape includes a filter valve body. Both ends of the filter valve body are fixedly connected with connecting pipes. A first ring is rotatably connected inside each of the two connecting pipes. A group of connecting rods is rotatably connected inside each of the two first rings. A second ring is sleeved inside each of the two connecting pipes. A group of clamping blocks is rotatably connected inside each of the two second rings. The two groups of connecting rods are respectively sleeved inside the two groups of clamping blocks. A filter element body is sleeved inside each of the two connecting pipes. The two filter element bodies are respectively clamped on the inner surfaces of the two groups of clamping blocks. A quick replacement mechanism is fixedly connected inside each of the two connecting pipes. The quick replacement mechanism includes two first springs, and the two first springs are respectively fixedly connected inside the two connecting pipes.

[0009] Preferably, a ball bead is sleeved on the inner surface of each of the two first springs, and a group of clamping grooves are formed inside each of the two first rings.

[0010] Preferably, a handle is fixedly connected to the outer surface of the first ring.

[0011] Preferably, arc grooves are formed inside both of the connecting pipes.

[0012] Preferably, sealing rings are sleeved inside both of the connecting pipes, and threaded joints are slidably connected to the outer surfaces of both of the connecting pipes.

[0013] Preferably, second springs are fixedly connected inside both of the connecting pipes, and limiting plates are fixedly connected to the upper ends of both of the second springs.

[0014] (III) Beneficial effects

[0015] First, when installing the filter element body, the filter element body is sleeved into the connecting pipe. Pull the handle to drive the first ring to rotate counterclockwise. When the first ring rotates, the clamping block is pulled to rotate through the connecting rod. The clamping block rotates inward to fit the surface of the filter element body, clamping and fixing it to ensure its stable installation. When the filter element body needs to be disassembled and maintained after long-term use, pull the first ring to rotate clockwise to release the clamping and fixing of the filter element body, and then the filter element body can be poured out. The operation is simple and convenient for maintenance. The filter element body can be easily taken out for cleaning and maintenance to keep the inside of the filter valve body clean and extend the service life of the equipment.

[0016] Second, when the filter element body is sleeved into the connecting pipe for installation, the limiting plate is pushed to slide downward by the second spring, and then inward through the filter element body. After the filter element body is pushed in place, the limiting plate is driven to slide upward and protrude by the acting force of the second spring. When the limiting plate slides out, it makes a sound to remind the operator that the filter element body is installed in place. When the filter element body needs to be taken out for maintenance, turn the first ring to release the clamping of the filter element body. At this time, press the filter element body, and then the filter element body can be poured out. It is convenient for positioning during the installation of the filter element body, avoiding the situation that the filter element body is clamped with surface damage even when it is installed obliquely, and improving the stability of the device during use.

Specific implementation mode

[0023] In the embodiment of the present application, by providing a square double-layer gas filter valve, it effectively solves the problem that the square filter valve usually relies on installing two filter elements to improve the filtration efficiency. However, the existing installation methods of the filter elements usually involve screwing the filter elements in by threading or installing them by screwing bolts. Performing screwing operations in a narrow space is rather cumbersome, resulting in time-consuming disassembly and maintenance, and it is not conducive to quickly replacing the filter elements. When installing the filter element body, the filter element body is sleeved into the connecting pipe, and the handle is pulled to drive the first ring to rotate counterclockwise. When the first ring rotates, the clamping block is pulled to rotate through the connecting rod. The clamping block rotates inward and fits with the surface of the filter element body to clamp and fix it, ensuring its stable installation. When the filter element body needs to be disassembled and maintained after long-term use, the first ring is pulled to rotate clockwise to release the clamping and fixing of the filter element body, and then the filter element body can be poured out. The operation is simple and convenient for maintenance operations. The filter element body can be easily taken out for cleaning and maintenance to keep the inside of the filter valve body clean and extend the service life of the equipment.

[0024] Embodiment

[0025] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the technical problem that the mouth-shaped filter valve usually relies on installing two filter elements to improve the filtration efficiency, but the existing installation method of the filter element is usually to screw the filter element or install it by screwing bolts, and the screwing operation in a narrow space is relatively cumbersome, resulting in time-consuming disassembly and maintenance, and is not conducive to quickly replacing the filter element. The general idea is as follows: A mouth-shaped double-layer gas filter valve includes a filter valve body 11. Both ends of the filter valve body 11 are fixedly connected with connecting pipes 12. A first ring 13 is rotatably connected inside both connecting pipes 12. A group of connecting rods 14 are rotatably connected inside both first rings 13. A second ring 15 is sleeved inside both connecting pipes 12. A group of clamping blocks 16 are rotatably connected inside both second rings 15. The two groups of connecting rods 14 are respectively sleeved inside the two groups of clamping blocks 16. A filter element body 17 is sleeved inside both connecting pipes 12. The two filter element bodies 17 are respectively clamped on the inner surfaces of the two groups of clamping blocks 16. A quick-change mechanism is fixedly connected inside both connecting pipes 12. The quick-change mechanism includes two first springs 18. The two first springs 18 are respectively fixedly connected inside the two connecting pipes 12. A ball bead 19 is sleeved on the inner surface of each of the two first springs 18. A group of clamping grooves 21 are opened inside both first rings 13. The two ball beads 19 are respectively adapted to the two groups of clamping grooves 21. A handle 22 is fixedly connected to the outer surface of the first ring 13. When installing the filter element body 17, the filter element body 17 is sleeved into the connecting pipe 12, and the handle 22 is pulled to drive the first ring 13 to rotate counterclockwise. When the first ring 13 rotates, the clamping block 16 is pulled to rotate through the connecting rod 14. The clamping block 16 rotates inward to fit with the surface of the filter element body 17 and clamp and fix it to ensure its stable installation. When the filter element body 17 needs to be disassembled and maintained after long-term use, the first ring 13 is pulled to rotate clockwise to release the clamping and fixing of the filter element body 17, and then the filter element body 17 can be dumped out. The operation is simple and convenient for maintenance operation. The filter element body 17 can be easily taken out for cleaning and maintenance to keep the inside of the filter valve body 11 clean and extend the service life of the equipment. When the first ring 13 rotates, the ball bead 19 is driven by the first spring 18 to be clamped into the clamping groove 21 to limit the rotating first ring 13.

[0026] An arc groove 23 is provided inside each of the two connecting pipes 12. The two handles 22 are respectively rotatably connected inside the arc groove 23. A sealing ring 24 is sleeved inside each of the two connecting pipes 12. A threaded joint 25 is slidably connected to the outer surface of each of the two connecting pipes 12. The filter valve body 11 and the gas pipeline are connected through the threaded joint 25. The two connecting pipes 12 respectively play the roles of intake and exhaust. The gas can provide multiple parallel flow paths through the mouth-shaped channel in the filter valve body 11, reducing the flow resistance of the fluid in the valve. When the pipeline is connected, the sealing ring 24 ensures the connection tightness. When the gas intakes and exhausts through the two connecting pipes 12, different-sized impurities can be filtered layer by layer through the two filter element bodies 17. The first filter element body 17 intercepts larger particles, and the second filter element body 17 further filters smaller particles.

[0027] A second spring 26 is fixedly connected inside each of the two connecting pipes 12. The upper ends of the two second springs 26 are fixedly connected with a limiting plate 27. The two limiting plates 27 are on the same horizontal line as the two filter element bodies 17. When the filter element body 17 is inserted into the connecting pipe 12 for installation, the second spring 26 squeezes the limiting plate 27 to slide downward, and then the filter element body 17 is inserted inward. After the filter element body 17 is pushed in place, the second spring 26 drives the limiting plate 27 to slide upward and protrude. When the limiting plate 27 slides out, it makes a sound to remind the operator that the filter element body 17 is installed in place. When the filter element body 17 needs to be taken out for maintenance, the first ring 13 is rotated counterclockwise to loosen the clamping of the filter element body 17. At this time, the filter element body 17 is pressed, and the filter element body 17 can be tilted out, which is convenient for positioning during the installation of the filter element body 17, avoiding the situation of clamping the filter element body 17 with inclination during installation and causing surface damage, and improving the stability of the device during use.

[0028] In view of the problems existing in the prior art, the present utility model provides a mouth-shaped double-layer gas filter valve. When the filter element body 17 is installed, the filter element body 17 is inserted into the connecting pipe 12. The handle 22 is pulled to drive the first ring 13 to rotate counterclockwise. When the first ring 13 rotates, the clamping block 16 is pulled to rotate inward through the connecting rod 14. The clamping block 16 rotates inward to fit with the surface of the filter element body 17 and clamps and fixes it to ensure its stable installation. When the filter element body 17 needs to be disassembled and maintained after long-term use, the first ring 13 is rotated clockwise to loosen the clamping and fixing of the filter element body 17, and the filter element body 17 can be tilted out. The operation is simple and convenient for maintenance. The filter element body 17 can be easily taken out for cleaning and maintenance to keep the inside of the filter valve body 11 clean and extend the service life of the equipment.

[0029] Working principle:

[0030] First step, connect the filter valve body 11 and the gas pipeline through the threaded joint 25. The two connecting pipes 12 respectively play the roles of air inlet and air outlet. The gas can provide multiple parallel flow paths through the mouth-shaped channel in the filter valve body 11, reducing the flow resistance of the fluid in the valve. When connecting the pipelines, the sealing ring 24 ensures the connection tightness. When the gas enters and exits through the two connecting pipes 12, different-sized impurities can be filtered layer by layer through the two filter element bodies 17. The first filter element body 17 intercepts larger particles, and the second filter element body 17 further filters smaller particles.

[0031] Second step, when installing the filter element body 17, insert the filter element body 17 into the connecting pipe 12. Pull the handle 22 to drive the first ring 13 to rotate counterclockwise. When the first ring 13 rotates, it pulls the clamping block 16 to rotate through the connecting rod 14. The clamping block 16 rotates inward and fits with the surface of the filter element body 17 to clamp and fix it, ensuring its stable installation. When the filter element body 17 needs to be disassembled and maintained after long-term use, pull the first ring 13 to rotate clockwise to release the clamping and fixing of the filter element body 17, and then the filter element body 17 can be dumped out. The operation is simple and convenient for maintenance. The filter element body 17 can be easily taken out for cleaning and maintenance to keep the inside of the filter valve body 11 clean and extend the service life of the equipment. When rotating the first ring 13, the ball 19 is driven by the first spring 18 to snap into the card slot 21 to limit the rotation of the first ring 13. When the filter element body 17 is inserted into the connecting pipe 12 for installation, the limiting plate 27 is pushed downward by the second spring 26 and then passes through the filter element body 17 inward. After the filter element body 17 is pushed in place, the limiting plate 27 slides upward and extends out under the action of the second spring 26. When the limiting plate 27 slides out, it makes a sound to remind the operator that the filter element body 17 is installed in place. When the filter element body 17 needs to be taken out for maintenance, turn the first ring 13 to release the clamping of the filter element body 17. At this time, press the filter element body 17, and the filter element body 17 can be dumped out, which is convenient for positioning during the installation of the filter element body 17 and avoids the situation of clamping the filter element body 17 with surface damage when it is installed obliquely, improving the stability of the device during use.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
