[0029] Schematic check valve
[0030] refer to Figures 1 to 4 According to a preferred embodiment of the one-way valve of the present utility model, it should be noted that the structure of the one-way valve is as follows Figure 1 As shown, it includes a valve housing 10, the valve housing 10 has a first opening 101, a cavity and a second opening 106, the first opening 101 and the second opening 106 are both connected to the outside, and the first opening 101 and the second opening 106 are also connected to the cavity. It should be noted that the above-mentioned cavity consists of a first guide hole 102, a second guide hole 103, an assembly hole 104 and a third guide hole 105, and the first opening 101 and the second opening 106 are respectively located at the two ends of the valve housing 10, and the first guide hole 102 is connected to the first opening 101, and the second opening 106 is connected to the third guide hole 105.
[0031] It should also be noted that the one-way valve further includes a moving component 20, which is movably disposed in the cavity, and the moving component 20 is configured so that the valve housing 10 can only flow in one direction, wherein when the moving component 20 is located at the initial position, the moving component 20 is configured to block the second guide hole 103. Specifically, when the external fluid flows from the first opening 101 to the second opening 106, the moving component 20 is subjected to the force of the external fluid and moves a predetermined distance toward the direction close to the second opening 106, so that the moving component 20 no longer blocks the second guide hole 103, so that the external fluid passes through the first opening 101, the first guide hole 102, the second guide hole 103, the assembly hole 104, the third guide hole 105 and the second opening 106 in sequence.
[0032] Further, the moving component 20 includes a moving member 21, the moving member 21 is placed in the assembly hole 104, and the moving member 21 has a supporting end 211 and a connecting end 212, the supporting end 211 is connected to the connecting end 212, that is, the supporting end 211 and the connecting end 212 are integrally formed. It is worth mentioning that the outer wall of the supporting end 211 contacts the wall surface forming the assembly hole 104 and close to the second guide hole 103, and at the same time, the end of the supporting end 211 away from the connecting end 212 is facing the second guide hole 103. Specifically, the cross-sectional size of the supporting end 211 is larger than the aperture of the second guide hole 103, so that the moving member 21 can block the second guide hole 103.
[0033] It should be noted that the outer wall of the abutting end 211 has a first annular mounting groove 21101, and a sealing member is disposed in the first annular mounting groove 21101. The sealing member may be a rubber sealing ring. The sealing member is configured to ensure the sealing performance of the junction between the abutting end 211 and the second guide hole 103.
[0034] It is worth mentioning that the cross-sectional shape of the connecting end 212 is as follows: Figure 3As shown, the connecting end 212 has a cylinder 2121 and three guide plates 2122, one end of the cylinder 2121 is connected to the end of the abutting end 211 away from the second flow guide hole 103, and the three guide plates 2122 are evenly arranged on the outer wall of the cylinder 2121. In addition, the ends of the three guide plates 2122 away from the cylinder 2121 are also in contact with the wall surface forming the third flow guide hole 105, so that the moving part 21 can move in the direction close to the second opening 106, and the maximum size of the assembly hole 104 is greater than the maximum size of the moving part 21, so that the external fluid passes through the second flow guide hole 103 and is guided to the connecting end 212.
[0035] Furthermore, the end of the connection end 212 away from the abutting end 211 also has an insertion hole 21201, and the bottom wall forming the insertion hole 21201 also has a protrusion 2123, and the cross section of the protrusion 2123 is columnar. In addition, the end of the protrusion 2123 away from the insertion hole 21201 also has a connection block 2124, one end of the connection block 2124 is connected to the protrusion 2123, and the other end passes through the insertion hole 21201 and is placed in the third guide hole 105.
[0036] Furthermore, the moving assembly 20 further includes an elastic member 22, which is sleeved on the protrusion 2123, and one end of the elastic member 22 abuts against the bottom of the insertion hole 21201, and the other end passes through the insertion hole 21201 and is located in the third guide hole 105. The sum of the lengths of the protrusion 2123 and the connecting block 2124 is greater than the length of the elastic member 22.
[0037] Furthermore, the moving assembly 20 further includes a first stopper 23, which is disc-shaped and has a plurality of guide grooves 2301 for external fluid to pass through, and one end of the connecting block 2124 away from the protrusion 2123 is fixedly connected to the center of the first stopper 23. Specifically, Figure 3 and Figure 4As shown, the center of the first stopper 23 has a mounting groove, and the mounting groove is interference-fitted with the connecting block 2124, thereby limiting the position of the first stopper 23. The wall surface forming the third guide hole 105 also has a second annular mounting groove 107, and the first stopper 23 is arranged in the second annular mounting groove 107. In addition, the aperture of the third guide hole 105 located between the mounting hole 104 and the second annular mounting groove 107 is smaller than the size of the second annular mounting groove 107, and the aperture of the third guide hole 105 on the side of the second annular mounting groove 107 away from the mounting hole 104 is larger than the size of the second annular mounting groove 107, that is, the side of the second annular mounting groove 107 away from the mounting hole 104 is connected to the third guide hole 105.
[0038] It should also be noted that the first limit member 23 of our company's previous product is a plastic part, and the first limit member 23 is placed in the second annular mounting groove 107 by extrusion deformation. However, when the movable component 20 no longer blocks the second guide hole 103, if the impact pressure of the external fluid is too large, the first limit member 23 made of plastic is more likely to burst due to excessive pressure, thereby failing to meet the use requirements. Therefore, the first limit member 23 is changed to a metal part, thereby greatly improving the pressure-bearing capacity of the first limit member 23, which can meet the use requirements under a predetermined pressure, and the installation method of the first limit member 23 through deformation is also more prone to damage.
[0039] It should also be noted that the moving assembly 20 further includes a second stopper 24, and the wall surface forming the third guide hole 105 also has a third annular mounting groove 108, the second stopper 24 is arranged in the third annular mounting groove 108, the second stopper 24 is located on the side of the first stopper 23 away from the assembly hole 104, and the first stopper 23 abuts against the second stopper 24, thereby limiting the position of the first stopper 23. It should also be noted that the second stopper 24 can be implemented as a rubber ring. In addition, the size of the third annular mounting groove 108 is larger than the size of the second annular mounting groove 107.
[0040] It is worth mentioning that when the external fluid impacts the moving part 21, the moving part 21 moves a predetermined distance toward the first limit part 23, and at the same time, the elastic part 22 is deformed by the force of the moving part 21. Conversely, when the external fluid no longer squeezes the moving part 21, the moving part 21 is reset by the elastic potential energy of the elastic part 22.
[0041] In summary, the one-way valve according to the embodiment of the present application is explained, which provides the one-way valve with advantages such as low cost, simple structure, and high practicality.
[0042] It is worth mentioning that in the embodiment of the present application, the one-way valve has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the one-way valve provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further facilitating product promotion and use.
