[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0018] like Figure 1-Figure 11 As shown, a detachable one-way valve proposed in one embodiment of the present application includes: A housing 1, wherein a spherical groove 2 is constructed therein, and cylindrical grooves 3 are opened on both sides of the housing 1, the inner diameter of the spherical groove 2 is larger than the inner diameter of the cylindrical groove 3, and the cylindrical grooves 3 are connected to the spherical groove 2, and the center of the spherical groove 2 is located on the axis of the cylindrical groove 3; A rotating rod 4 is provided with a handle 5 at the top thereof, through which the rotating rod 4 can be rotated, and the bottom end of the rotating rod 4 rotates to penetrate the spherical groove 2. The rotating rod 4 vertically penetrates the shell 1, and the center of the spherical groove 2 is located in the axial direction of the rotating rod 4, and a ball 6 is connected thereto, and the ball 6 fits the inner wall of the spherical groove 2. A through groove 7 is constructed on the ball 6, and the two cylindrical grooves 3 are connected through the through groove 7. The structure here is similar to a spherical valve. By rotating the rotating rod 4, the through groove 7 and the cylindrical groove 3 can be misaligned to close the valve. The valve here is a general term for the overall structure of the present application. A one-way valve body 8 is provided in the through groove 7. When the valve is opened, the medium passes through the one-way valve body 8 in the through groove 7 to achieve one-way conduction, thereby combining manual control and one-way valve functions; The sliding grooves 9 are symmetrically constructed on the other two sides of the spherical groove 2. The sliding grooves 9 are arranged on both sides of the extension direction of the cylindrical groove 3 and are perpendicular to the axis of the cylindrical groove 3. The sliding blocks 10 are slidably matched therein. The sliding blocks 10 are in contact with the spheres 6. With such a design, when the through groove 7 is connected with the two cylindrical grooves 3, the outer side of the sphere 6 can contact the two sliding blocks 10 and force the two to move toward the opposite ends of the sliding groove 9. Two U-shaped plates 11 are respectively slidably mounted on both sides of the shell 1. A guide column 1101 is constructed on the U-shaped plate 11. The guide column 1101 is slidably inserted into the shell 1. Both sides of the shell 1 are equipped with U-shaped openings 12. The openings of the U-shaped openings 12 face upwards and cover the notches of the cylindrical groove 3. The arc center of the inner side of the arc of the U-shaped opening 12 is located in the axial direction of the cylindrical groove 3, and the inner diameter of the cylindrical groove 3 is smaller than the arc diameter of the inner side of the arc of the U-shaped opening 12. The notch of the cylindrical groove 3 is paved with a sealing gasket 13, which is a rubber gasket. The prior art In the middle, the outer side of the connecting end of the large pipe 26 is mostly provided with a connecting ring 27, the arc diameter of the inner side of the arc of the U-shaped mouth 12 can be consistent with the outer diameter of the connecting ring 27, the arc diameter of the inner side of the arc of the U-shaped plate 11 is consistent with the outer diameter of the pipe 26, the sliding block 10 and the U-shaped plate 11 are connected by the transmission assembly 14, when the two sliding blocks 10 move back to back, the two U-shaped plates 11 move relative to each other, when the rotating rod 4 is rotated to make the through groove 7 and the sliding groove 9 on the same axis, the valve is in the disassembled state, and the two U-shaped plates 11 can be driven to move back to back. The two sliding blocks 10 can be respectively inserted into the two ends of the through groove 7 under the action of the transmission assembly 14, and the connecting ring 27 can enter between the U-shaped plate 11 and the U-shaped opening 12 through the opening of the U-shaped opening 12, and the pipe 26 can enter the inner side of the arc through the opening of the U-shaped plate 11. At this time, the pipe 26 can contact the sealing gasket 13 and align with the cylindrical groove 3, and then the two U-shaped plates 11 can be driven to move closer to each other, so that the two sliding blocks 10 can be separated from the through groove 7, and finally the through groove 7 can be aligned with the cylindrical groove 3 by rotating the rotating rod 4. The cylindrical groove 3 is connected, and the valve is in the installation state. The two sliding blocks 10 are moved away from each other under the resistance of the outer side of the ball 6. Under the action of the transmission component 14, the two U-shaped plates 11 are close to each other, and the connecting ring 27 is tightly against the sealing gasket 13, so that the installation of the valve is completed. When the ball 6, the ball groove 2 and the one-way valve body 8 are worn under the action of the medium, affecting the sealing of the valve, the ball 6 can be rotated to put the valve in the disassembly state, and the valve and the pipeline 26 can be quickly disassembled; It should be specifically explained that when the rotating rod 4 is rotated, the angle between the axis of the through groove 7 in the ball 6 and the axis of the cylindrical groove 3 and the sliding groove 9 is consistent. In this state, the through groove 7 and the cylindrical groove 3 are in a staggered state, the valve is in a closed state, and the sliding block 10 cannot enter the through groove 7, and it is not easy to affect the state of the two U-shaped plates 11; The present application adopts the design of the sliding block 10, so that the valve can be opened and closed and the valve and the pipe 26 can be disassembled and assembled by rotating the rotating rod 4. Compared with the prior art, the use of flanges is reduced, making the disassembly and assembly of the valve and the pipe 26 faster and more convenient.

[0019] like Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig.11 As shown, in some embodiments, the transmission assembly 14 includes a slider 1401, and a through groove 1402 is provided on both sides of the cylindrical groove 3. The through groove 1402 is not connected to the cylindrical groove 3. There are four through grooves 1402, which are symmetrically arranged on both sides of the shell 1 in pairs. The through grooves 1402 extend along the length direction of the cylindrical groove 3. The number of sliders 1401 is consistent with that of the four sliders 1401, and they are slidably installed in the multiple through grooves 1402 respectively. The sliders 1401 on the same side are connected to the U-shaped plate 11. The sliders 1401 on the same side here specifically refer to the sliders 1401 in the through grooves 1402 on both sides of the cylindrical groove 3. The two coaxial through grooves 1402 are connected through the sliding groove 9, which specifically refers to the through grooves 1402 located on the opposite sides of the sliding groove 9 and on the same axis. The through groove 1402 is connected to the spherical groove 2 through the sliding groove 9. The movable block 10 is hinged with hinged plates 1403 on both sides, and its ends are hinged with the slider 1401. An inclined surface 1404 is constructed in the through groove 1402. When the valve is in the installed state, the two sliding blocks 10 move away from each other under the resistance of the ball 6. The hinged plate 1403 is inclined in the through groove 1402 and fits with the inclined surface 1404. The slider 1401 on the same side can drive the hinged plate 1403 to drive the two U-shaped plates 11 to move closer to each other, so as to fix the valve and the pipeline 26. Conversely, when the valve is in the disassembled state, the two sliding blocks 10 can move closer to each other, and the hinged plate 1403 can push the two U-shaped plates 11 to move away from each other, so as to release the fixation of the valve and the pipeline 26. A sealing component 1405 is provided in the through groove 1402. The sealing component 1405 is used to improve the sealing between the through groove 1402 and the slider 1401.

[0020] like Figure 1 , Figure 4 , Figure 5 and Fig.11 As shown, in some embodiments, both ends of the U-shaped plate 11 are constructed with limit blocks 15, the limit blocks 15 are close to the U-shaped mouth 12, and the bottoms thereof are constructed with arc-shaped abutment surfaces 16. When the U-shaped plate 11 abuts the connecting ring 27 against the U-shaped mouth 12 to form a clamping fixation, the arc-shaped abutment surface 16 at the bottom of the limit block 15 can contact the top circumferential side of the connecting ring 27, thereby improving the fixing effect of the U-shaped plate 11 on the connecting ring 27 and further limiting the movement of the connecting ring 27 after installation.

[0021] like Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments, the sealing assembly 1405 includes a frustum-shaped protrusion 14051 constructed on the opposite side of the slider 1401, the frustum-shaped protrusion 14051 is arranged on the opposite side of the two sliders 1401 in the two coaxial through grooves 1402, and the outer diameter of the frustum-shaped protrusion 14051 gradually decreases from the through groove 1402 toward the sliding groove 9, the outer side of the frustum-shaped protrusion 14051 is an inclined surface 1404, and a contact surface 14052 is constructed in the through groove 1402, and the contact surface 1405 2 is also an inclined surface 1404, which is parallel to the outer side of the frustum-shaped projection 14051. When the two U-shaped plates 11 slide relatively and the connecting ring 27 contacts the sealing gasket 13, the frustum-shaped projection 14051 can contact closely with the contact surface 14052, so that the medium inside the valve is not easy to flow out through the through groove 1402. According to actual needs, a sealing ring 28 made of rubber can be laid on the contact surface 14052 to improve the sealing performance between the frustum-shaped projection 14051 and the contact surface 14052.

[0022] like Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments, the end of the sliding block 10 is constructed with an arc block 17, the arc outer diameter of the arc block 17 is consistent with the outer diameter of the sphere 6, the arc block 17 is in active contact with the sphere 6, the arc block 17 is an arc convex surface that contacts and overlaps the outer side of the sphere 6, and the contact part between the two is only one point. When the sphere 6 rotates, it is not easy to generate large friction. The opposite ends of the two sliding blocks 10 are provided with compression springs 18, which are the abbreviations of compression springs, and the other ends of the compression springs 18 are in contact with the sliding grooves. 9 conflicts with each other, and the compression spring 18 is used to provide a thrust forcing the sliding block 10 to move toward the ball 6. When the valve is in the disassembled state, the arc-shaped convex surface of the arc-shaped block 17 at the end of the slider 1401 automatically enters the end of the through groove 7 under the action of the compression spring 18, and drives the two U-shaped plates 11 away from each other, which is relatively convenient. When the rotating rod 4 is rotated, the arc-shaped convex surface of the arc-shaped block 17 can move in the direction away from the ball 6 under the conflict with the notch of the through groove 7 until it conflicts with the outer side of the ball 6.

[0023] like Figure 2 and Figure 3As shown, in some embodiments, cylindrical grooves 19 are provided on opposite sides of the shell 1, and a take-in / put-out port 20 connected to the sliding groove 9 is constructed in the middle thereof, and the inner diameter of the take-in / put-out port 20 is larger than the outer diameter of the compression spring 18. Since the spring is in a compressed state for a long time, it will indeed have an impact on the spring, and may even cause failure, affecting the normal use of the valve, so that the compression spring 18 can be disassembled and assembled through the take-in / put-out port 20, and a circular plate 21 is movably inserted in the cylindrical groove 19, and a sealing rubber ring 29 made of rubber is laid on the circular plate 21. A fixing mechanism 22 is provided on the shell 1, which is used to fix the circular plate 21 in the cylindrical groove 19. After the circular plate 21 is inserted into the cylindrical groove 19, the sealing rubber ring 29 can cover the take-in / put-out port 20, thereby improving the sealing of the valve body after installation.

[0024] like Figure 2 and Figure 3 As shown, in some embodiments, the fixing mechanism 22 includes a block 2201 constructed on the opposite side of the circular plate 21, a knob 2202 is provided on the outer side of the circular plate 21, a groove 2203 for accommodating the block 2201 is provided on the inner wall of the cylindrical groove 19, a receiving groove 32 for accommodating the compression spring 18 is constructed on the sliding block 10, and a top column 31 is constructed on the circular plate 21, which is movably connected with the receiving groove 32. After the circular plate 21 is inserted into the cylindrical groove 19, the circular plate 21 can be rotated by the knob 2202 so that the block 2201 can be inserted into the groove 2203, so that the circular plate 21 can be fixed in the cylindrical groove 19 against the contact. When the circular plate 21 rotates, the top column 31 can be inserted into the accommodating groove 32 and contact with the compression spring 18. A flexible pad 2204 is connected to the slot 2203. The flexible pad 2204 is a silicone pad, which is movably contacted with the block 2201. A guide slope 2205 is constructed on the peripheral side of the block 2201. The guide slope 2205 is designed to be able to contact and slide with the notch of the slot 2203 when the circular plate 21 rotates, so that the block 2201 can enter the slot 2203 easily. After the block 2201 contacts with the flexible pad 2204, the block 2201 can be firmly fixed in the slot 2203 through the contact force generated by the deformation of the flexible pad 2204.

[0025] like Figure 2 and Fig. 9 As shown, in some embodiments, a limit member 23 is provided on the top of the shell 1, which is used to adjust the rotation angle of the rotating rod 4. The difference between the valve closing state and the valve installation state is the rotation angle of the ball 6, that is, the rotating rod 4. The limit member 23 can avoid excessive rotation of the rotating rod 4 when closing the valve, thereby preventing the valve from being accidentally separated from the pipeline 26.

[0026] like Figure 2 and Fig. 9As shown, in some embodiments, the limiting member 23 includes a prism block 2301 constructed on the top of the shell 1, a limiting sleeve 2302 is movably sleeved on the rotating rod 4, and a prism groove 2303 for accommodating the prism block 2301 is constructed at the bottom of the limiting sleeve 2302. When the prism groove 2303 accommodates the prism block 2301, the limiting sleeve 2302 cannot rotate, and a stopper 2305 is constructed on the side of the rotating rod 4. An arc groove 2304 for accommodating the stopper 2305 is constructed on the limiting sleeve 2302, and the arc center of the arc groove 2304 is The angle is forty-five degrees. When the rotating rod 4 rotates, the stopper 2305 can slide in the arc groove 2304. At this time, the angle of the arc groove 2304 is the maximum rotation angle of the rotating rod 4 when the valve is closed. When the valve needs to be separated from the pipeline 26, the limiting sleeve 2302 can be pushed to slide upward to disengage the prism groove 2303 from the prism block 2301, and then the rotating rod 4 can be rotated. At this time, the limiting sleeve 2302 does not limit the rotation of the rotating rod 4, and the rotating rod 4 can drive the ball 6 to rotate ninety degrees, so that the valve is in a disassembled state.

[0027] like Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, in some embodiments, an opening 24 is provided on the top of the shell 1, and the opening 24 is cylindrical. The spherical groove 2 includes a first hemispherical groove 201 and a second hemispherical groove 202. The first hemispherical groove 201 is constructed in the shell 1. A plate body 25 is rotatably installed on the rotating rod 4, and the plate body 25 is cylindrical. The second hemispherical groove 202 is constructed at the bottom of the plate body 25 and plugs with the opening 24. When the second hemispherical groove 202 is inserted into the opening 24, it can cooperate with the first hemispherical groove 201 to form the spherical groove 2. The one-way valve body 8 can be detachably installed in the through groove 7. The one-way valve body 8 is the prior art, which includes a baffle 801 constructed in the through groove 7, on which a through hole 802 is provided, and the through hole 802 has an internal thread. A mounting plate 803 is connected, on which a piston column 804 slides and penetrates, and a return spring 805 is installed on the mounting plate 803, which is used to push the piston column 804 to block the through hole 802. The plate body 25 is threadedly connected to the shell 1, and the rotation direction of the rotating rod 4 is opposite to the thread direction of the plate body 25. After the limit sleeve 2302 is moved upward, the prism block 2301 can be rotated by a tool to separate the plate body 25 from the shell 1. A rubber ring 30 is laid along the opening 24. After the plate body 25 is fixedly installed in the shell 1, the plate body 25 conflicts with the rubber ring 30. This design makes the valve easy to disassemble and assemble, and also has the advantage of replacing a damaged one-way valve.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
