DETAILED DESCRIPTION

[0020] The above solutions are further described in the following in connection with specific examples. It should be understood that the examples are used to explain the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not mentioned are usually the conditions in the conventional experiments.

[0021] Example: A threaded plug-in valve convenient to install, such as Figures 1-4As shown, the device includes an oil manifold block 1, a first spring 101, a cartridge valve body 2, a sealing ring 4, a sealing ring 5, a butterfly valve 10, a worm gear 11, a worm 12, a rotating rod 13, and a filter screen 14. The cartridge valve body 2 is inserted into the oil manifold block 1. One end of the first spring 101 is welded to the inside of the oil manifold block 1, while the other end, not connected to the oil manifold block 1, contacts the lower end of the cartridge valve body 2. The sealing ring 4 is welded to the lower end of the cartridge valve body 2, with its outer ring tightly against the oil manifold block 1 to prevent the medium from seeping into the contact surface between the lower end of the cartridge valve body 2 and the oil manifold block 1 during transportation. The sealing ring 5 is welded to the lower end of the cartridge valve body 2 and replaces the lower end of the cartridge valve body 2 in contact with the first spring 101. 1. The other end is in close contact. The butterfly valve 10 is rotatably connected to the lower part of the oil manifold 1. The worm gear 11 is connected to the butterfly valve 10 by welding and is located inside the oil manifold 1. The rotating rod 13 is rotatably connected to the lower part of the oil manifold 1. Its leftmost end is provided with a knurled twist block for easy rotation. The worm 12 is connected to the rightmost end of the rotating rod 13 by welding and is located below the worm gear 11 and meshes with it. By rotating the rotating rod 13 clockwise or counterclockwise, the worm 12 meshes with the worm gear 11 in the forward or reverse direction, causing the worm gear 11 to rotate counterclockwise or clockwise, opening or closing the oil manifold 1. It also includes a cone block 3, a mounting plate 6, a guide rod 7, a second spring 8, a clamping block 9, and a rotating frame 15. The cone block 3 is connected by welding. Two mounting plates 6 are positioned slightly below the middle of the cartridge valve body 2 and are welded to the top edge of the oil passage block 1. Each guide rod 7 is slidably connected to each mounting plate 6, with the diameter of the end contacting the corresponding mounting plate 6 being larger than the diameter of the main body to prevent the guide rod 7 from detaching from the corresponding mounting plate 6. Each clamping block 9 is welded to the other end of each guide rod 7 that is not in contact with the corresponding mounting plate 6. Each second spring 8 is sleeved on the outside of each guide rod 7, with its two ends fixedly connected to the corresponding mounting plate 6 and the corresponding clamping block 9, respectively. The rotating frame 15 is rotatably connected to a position slightly above the middle of the cartridge valve body 2, and the distance between its bottom end and the top of the cone block 3 is equal to the thickness of the clamping block 9. The clamping block 9 is located between the rotating frame 15 and the cone block 3. The arc surface of one end of the clamping block 9 is in close contact with the cartridge valve body 2, so that the cartridge valve body 2 is locked inside the oil passage block 1. The clamping block 9 has a cone surface that matches the cone block 3. The cone surface is located above the arc surface. When the cartridge valve body 2 is placed inside the oil passage block 1, the cone block 3 contacts the cone surface of the clamping block 9 and squeezes the clamping block 9 to move outward. When the cone block 3 is separated from the cone surface of the clamping block 9, the clamping block 9 moves inward with the assistance of the second spring 8. The filter screen 14 is connected to the lower geometric center of the oil passage block 1 by welding and is directly below the blade part of the butterfly valve 10. When the medium discharged from the cartridge valve body 2 is discharged through the butterfly valve 10, the filter screen 14 filters the impurities in the medium and improves the purity of the medium.

[0022] like Figure 1 and Figure 3As shown, the connecting blocks 91 and the protrusions 151 are further included, each of the connecting blocks 91 is connected to the top end of each of the clamping blocks 9 by welding, the two protrusions 151 are symmetrically arranged front and back, and are connected to the lower part of the rotating frame 15 by welding and are at the same height as the two connecting blocks 91, when the protrusions 151 rotate with the rotating frame 15, the connecting blocks 91 are contacted and extruded to move outward.

[0023] When the threaded plug-in valve needs to be installed, the operator first inserts the plug-in valve body 2 into the oil passage block 1, in the process of insertion, the tapered block 3 first contacts the tapered surfaces of the two clamping blocks 9 and extrudes the two clamping blocks 9 to move outward along the tapered surfaces, and the second spring 8 is compressed at the same time, when the plug-in valve body 2 is completely inserted into the oil passage block 1, the sealing ring 5 contacts and extrudes the first spring 101 to be compressed, the tapered block 3 is separated from the two clamping blocks 9, and the second spring 8 restores to the original state, so as to promote the two clamping blocks 9 to move inward to clamp the plug-in valve body 2, at the same time, the tapered block 3 cooperates with the rotating frame 15 to limit the two clamping blocks 9, so as to ensure that the two clamping blocks 9 tightly clamp the plug-in valve body 2, thus, the installation process of the plug-in valve body 2 is completed.

[0024] When the plug-in valve body 2 needs to be disassembled, the rotating frame 15 is rotated clockwise by 90 degrees, the two protrusions 151 rotate clockwise by 90 degrees with the rotating frame 15, contact and extrude the two connecting blocks 91 to move outward, the two clamping blocks 9 move outward with the two connecting blocks 91, and the plug-in valve body 2 is loosened, at this time, the first spring 101 restores to the original state, so as to promote the plug-in valve body 2 to move upward and slightly pop out from the oil passage block 1, so as to facilitate the plug-in valve body 2 to be pulled out, after the plug-in valve body 2 is pulled out, the rotating frame 15 is rotated counterclockwise by 90 degrees, the two protrusions 151 rotate counterclockwise by 90 degrees with the rotating frame 15, and then return to the initial position to be separated from the two connecting blocks 91, the second spring 8 restores to the original state, so as to promote the two clamping blocks 9 to move inward, the two connecting blocks 91 move inward with the two clamping blocks 9 to return to the initial position, thus, the disassembly process of the plug-in valve body 2 is completed.

[0025] The above embodiment is only a preferred embodiment of the present application, and is not used to limit the scope of the present application, therefore, equivalent changes made according to the content described in the present application claims should be included in the scope of the present application claims.
