Description

Technical Field

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

[0002] A one-way valve is a valve that allows fluid to flow only along the inlet, but not back through the outlet. 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.

[0003] In the existing one-way valve group, when liquid enters the cavity of the one-way valve, the spring inside the one-way valve for supporting the closing block is immersed in the liquid inside the cavity. If the liquid itself is corrosive, the life of the spring will be reduced, thereby reducing the service life of the equipment. At the same time, due to the different positions of the reserved mounting holes above the mounting frame, it is necessary to drill holes above the mounting frame or replace the mounting frame when replacing the reflux valve body.

[0009] As a preferred technical solution of the utility model, the width of the water blocking plate 1 and the water blocking plate 2 is the same as the inner wall width of the extension shell, and the side of the water blocking plate 1 and the water blocking plate 2 close to the fixed block is connected to the outer wall of the fixed block.

[0010] As a preferred technical solution of the utility model, the guide rail 1 penetrates the fixed block, and the guide rail 2 penetrates the water blocking block.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The one-way valve group structure drives the water blocking block to move through the water flow, and the water blocking block drives the fixed block to move. The fixed block pulls the water blocking plate 1 and pushes the water blocking plate 2 at the same time, so that when the fixed block moves, the water blocking plate 1 and the water blocking plate 2 can still isolate the inner wall of the extension shell and the mounting frame, so that the spring inside the extension shell is protected by the water blocking plate 1 and the water blocking plate 2, so that it will not contact the liquid inside the mounting frame, and the extension shell will not be corroded, thereby extending the service life of the extension shell.

[0013] 2. The one-way valve group structure drives the two adjusting foot assemblies to move in opposite directions by rotating the threaded rod so that the threaded rod drives the two adjusting foot assemblies to move in opposite directions through the rotation of the outer wall thread, thereby adjusting the distance between the two adjusting foot assemblies. The twisting head drives the gear to rotate, and the rotation of the gear drives the two racks to slide in opposite directions on the inner wall of the moving block, thereby causing the two connecting feet to move in opposite directions, thereby adjusting the distance between the connecting feet to suit different installation positions above the mounting frame.

A guide rail 13 is fixedly installed on the inner wall of the extension shell 8, and a spring 14 is provided on the outer wall of the guide rail 13. A guide rail 2 15 is fixedly installed on the inner wall of the mounting frame 1, and a threaded rod 16 is rotatably connected to the inner wall of the fixing seat 2. An adjusting foot assembly 17 is provided on the inner wall of the fixing seat 2. In the above structure, the number of the adjusting foot assemblies 17 is two, and the two water blocking plates 11 are symmetrically distributed on both sides of the bottom of the mounting frame 1.

[0023] In a preferred embodiment, the adjusting foot assembly 17 includes a moving block 1701, the inner wall of the moving block 1701 is rotatably connected to a gear 1702, the inner wall of the moving block 1701 is slidably connected to a rack 1703, the end of the rack 1703 away from the gear 1702 is fixedly installed with a connecting foot 1704, the inner wall of the connecting foot 1704 is rotatably connected to a bolt 1705, and the bottom of the gear 1702 is fixedly installed with a twisting head 1706. In the above structure, by rotating the twisting head 1706, the twisting head 1706 drives the gear 1702 to rotate, the gear 1702 drives the rack 1703 to move, the rack 1703 drives the connecting foot 1704 to move, and the twisting head 1706 is fixed above the mounting frame 1 by the bolt 1705.

[0024] In a preferred embodiment, the rack 1703 is parallel to the gear 1702, and the rack 1703 and the gear 1702 are meshed. In the above structure, by rotating the gear 1702, the gear 1702 meshes with the rack 1703 to drive the rack 1703 to move laterally on the inner wall of the moving block 1701.

[0025] In a preferred embodiment, the number of racks 1703 and connecting feet 1704 is two, and the two racks 1703 are symmetrically distributed on both sides of the inner wall of the mounting frame 1, and the two connecting feet 1704 are symmetrically distributed at one end of the two racks 1703. In the above structure, by rotating the gear 1702, the gear 1702 drives the two racks 1703 to move to both sides at the same time, and then the two racks 1703 drive the two connecting feet 1704 to move to both sides, thereby adjusting the distance between the two connecting feet 1704.

[0026] In a preferred embodiment, the width of the water blocking plate 11 and the water blocking plate 2 12 is the same as the width of the inner wall of the extension shell 8, and the water blocking plate 11 and the water blocking plate 2 12 are connected to the outer wall of the fixed block 10 on one side close to the fixed block 10. In the above structure, the mounting frame 1 and the inner wall of the extension shell 8 are separated by the water blocking plate 11 and the water blocking plate 2 12, so that the liquid is blocked by the water blocking plate 11 and the water blocking plate 2 12, so that the liquid cannot enter the inner wall of the extension shell 8. When the fixed block 10 moves, the fixed block 10 pulls the water blocking plate 1 11 to move in the direction of the water blocking plate 2 12, so that the water blocking plate 2 12 moves toward the inside of the mounting frame 1, so that the liquid cannot enter the inner wall of the extension shell 8 during sliding.

[0027] In a preferred embodiment, guide rail 13 passes through the fixed block 10, and guide rail 2 15 passes through the water blocking block 9. In the above structure, the fixed block 10 and the water blocking block 9 are in a fixed relationship, and the moving trajectory of the water blocking block 9 is limited by guide rail 1 13 and guide rail 2 15, so that the water blocking block 9 will not tilt on the inner wall of the mounting frame 1.

[0028] Working principle: when in use, water is injected into the water inlet pipe 6, so that the liquid in the water inlet pipe 6 flows to the inside of the three inlet pipes 4 through the diverter pipe 5, and the ball valve 7 is turned to open the ball valve 7. The water flows through the ball valve 7 to the outside of the water blocking block 9, and the water blocking block 9 is pushed to move along the guide rail 2 15 by the pressure of the water flow. The fixed block 10 is driven to move by the movement of the water blocking block 9. The fixed block 10 pulls the water blocking plate 1 11 to move and pushes the water blocking plate 2 12 to move, so that the water blocking plate 2 12 moves toward the inside of the mounting frame 1. At this time, the fixed block 10 moves on the outer wall of the guide rail 1 13 to compress the spring 14, and the extension shell 8 is separated from the inner cavity of the mounting frame 1 by the water blocking plate 1 11 and the water blocking plate 2 12, so that the inner cavity of the mounting frame 1 The liquid in the cavity cannot enter the inner wall of the extension shell 8, thereby protecting the extension shell 8, and the liquid inside the mounting frame 1 cannot contact the extension shell 8, thereby protecting the extension shell 8. When the reflux valve is replaced, the threaded rod 16 is rotated, and the threaded rod 16 drives the two adjusting foot assemblies 17 to move in the opposite direction on the outer wall of the threaded rod 16 to adjust the distance between the two adjusting foot assemblies 17. When the distance of the adjusting foot assemblies 17 is adjusted, the fixing seat 2 is flipped over and the gear 1702 is rotated, so that the gear 1702 drives the two racks 1703 to move to both sides at the same time, and then the two racks 1703 drive the two connecting feet 1704 to move to both sides, thereby adjusting the distance between the two connecting feet 1704.
