Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a plug-in type hydraulically controlled one-way valve. Background Art

[0002] A one-way valve is a valve that allows fluid to flow only along the inlet, but the medium at the outlet cannot flow back. It is commonly known as a one-way valve. A one-way valve is also called a check valve or a non-return valve. It is used in hydraulic systems to prevent oil from flowing in the opposite direction, or in pneumatic systems to prevent compressed air from flowing in the opposite direction. There are two types of one-way valves: straight-through and right-angle. Straight-through one-way valves are installed on the pipeline with threaded connections.

[0003] However, in the existing one-way valve, the valve seat and the valve housing are integrally formed. If the internal valve core and spring are damaged, the valve needs to be replaced as a whole, thereby increasing the cost of use. For this reason, a plug-in hydraulically controlled one-way valve is proposed. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a plug-in type hydraulically controlled one-way valve.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a plug-in hydraulically controlled one-way valve, including a valve housing, a plurality of drainage holes are provided on the surface of the valve housing, and slots are provided on the inner walls on both sides of the drainage hole, and positioning holes are provided on the front inner wall and the back inner wall of the slot, a filtering structure is provided in the drainage hole, a connecting pipe is fixedly provided at one end of the valve housing, a valve core is provided in the valve housing, a first spring is sleeved on the valve core, and a valve seat is movably provided at one end of the valve housing.

[0006] As a further description of the above technical solution:

[0007] A threaded sleeve is fixedly provided at one end of the valve seat close to the valve housing. The outer surface and inner wall of the threaded sleeve are both provided with patterns. The patterns on the inner wall of the threaded sleeve are matched with the connecting pipe.

[0008] As a further description of the above technical solution:

[0009] Two protrusions are fixedly arranged on the outside of the valve housing, and a sealing ring is sleeved on the outside of the valve housing. The sealing ring is located between the two protrusions.

[0010] As a further description of the above technical solution:

[0011] The filtering structure comprises a filtering plate clamped with the drainage hole, and clamping blocks are fixedly provided on both sides of the filtering plate, and the clamping blocks are matched with the clamping grooves.

[0012] As a further description of the above technical solution:

[0013] Two receiving grooves are provided on the card block, and two through grooves are provided on the front side of the card block. The through grooves are communicated with the receiving grooves, and a second spring is fixedly provided in the receiving groove, a positioning rod is fixedly provided at one end of the second spring, a pull rod is fixedly provided on the positioning rod, and one end of the pull rod passes through the through groove and is fixedly provided with a pull handle.

[0014] As a further description of the above technical solution:

[0015] The number of the drainage holes is eight, and the eight drainage holes are arranged in a circular equidistant array.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the plug-in hydraulically controlled one-way valve is provided with a threaded sleeve and a connecting pipe. When the internal components of the one-way valve are damaged and need to be replaced, the valve housing is fixed, and then the valve seat is rotated counterclockwise. The valve seat drives the threaded sleeve to rotate. When the threaded sleeve is separated from the connecting pipe, the valve seat can be separated from the valve housing, and the internal components can be taken out and replaced. For the non-integrated one-way valve, when the internal components of the equipment are damaged, they can be disassembled and the damaged components can be replaced without replacing the valve as a whole, thereby reducing the use cost.

[0018] 2. Compared with the prior art, the plug-in hydraulically controlled one-way valve is provided with a card slot, a positioning hole and a filtering structure. The filtering structure can filter the liquid entering the valve body and then discharge it, preventing impurities in the water from affecting the normal operation of the unit. The position of the positioning rod can be changed by pulling the pull rod to disengage it from the positioning hole, so that the filter plate can be quickly disassembled, which is convenient for subsequent replacement and maintenance.

[0030] Reference Figure 2 In order to separate the valve seat 11 from the valve housing 1, a threaded sleeve 12 is fixedly provided at one end of the valve seat 11 close to the valve housing 1. The outer and inner walls of the threaded sleeve 12 are provided with patterns. The inner wall patterns of the threaded sleeve 12 match the connecting pipe 8. The threaded sleeve 12 can be driven by rotating the valve seat 11. When the threaded sleeve 12 and the connecting pipe 8 are separated, the internal components of the device can be taken out and replaced. For a non-integrated one-way valve, when the internal components of the device are damaged, they can be disassembled and the damaged components can be replaced without replacing the valve as a whole, thereby reducing the use cost.

[0031] Reference Figure 4 to Figure 5In order to achieve the purpose of filtering the liquid, the filter structure 5 includes a filter plate 501 that is clamped with the discharge hole 2. Blocks 502 are fixedly provided on both sides of the filter plate 501. The block 502 is adapted to the clamping slot 3. Two receiving slots 503 are provided on the block 502. Two through slots 504 are provided on the front of the block 502. The through slots 504 are communicated with the receiving slots 503. A second spring 505 is fixedly provided in the receiving slot 503. A positioning rod 506 is fixedly provided at one end of the second spring 505. A pull rod 507 is fixedly provided on the positioning rod 506. One end of the pull rod 507 passes through the through slot 504 and is fixedly provided with a pull handle. The filter structure 5 can filter the liquid entering the valve body and then discharge it to prevent impurities in the water from affecting the normal operation of the unit. The position of the positioning rod 506 can be changed by pulling the pull rod 507 to make it detach from the positioning hole 4, so as to realize the rapid disassembly of the filter plate 501 and facilitate the subsequent replacement and maintenance.

[0032] Working principle: When the components inside the one-way valve are damaged and need to be replaced, fix the valve housing 1, then rotate the valve seat 11 counterclockwise, and the valve seat 11 drives the threaded sleeve 12 to rotate. When the threaded sleeve 12 is separated from the connecting pipe 8, the valve seat 11 can be separated from the valve housing 1, and the internal components can be taken out and replaced. For non-integrated one-way valves, when the internal components of the equipment are damaged, they can be disassembled and the damaged components can be replaced without replacing the valve as a whole, which reduces the cost of use. The filter structure 5 can filter the liquid entering the valve body before discharging it to prevent impurities in the water from affecting the normal operation of the unit. When the filter plate 501 needs to be replaced or cleaned, the two sets of pull rods 507 are pulled inward, and the two sets of pull rods 507 drive the two sets of positioning rods 506. When the positioning rods 506 are out of the positioning holes 4, the filter plate 501 is pulled upward to be disassembled. When installing, the two sets of pull rods 507 are pulled inward to make the positioning rods 506 completely retracted into the storage grooves 503, and then the card block 502 is placed in the card groove 3, and then the pull rod 507 is released. Under the thrust of the second spring 505, the two positioning rods 506 are inserted into the two positioning holes 4, and the installation of the filter plate 501 is completed.
