Description
Technical Field
The utility model relates to a check valve field, concretely relates to seal ring formula check valve.
Background
The check valve is commonly called as a check valve, fluid can only flow along the water inlet, and the medium at the water outlet cannot flow back. Check valves are also known as check valves or check valves. For preventing reverse flow of oil in hydraulic systems or for preventing reverse flow of compressed air in pneumatic systems. The check valve has a straight-through type and a right-angle type, but the right-angle type check valve has a complex structure, heavy weight and short service life at present, so that the applicant provides a novel sealing ring type check valve, which enables fluid to flow in one direction only and can control the flow of the fluid at the same time.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to solve the above-mentioned deficiencies of the prior art,
a seal ring type check valve is provided.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a seal ring formula check valve, is including both ends open-ended casing, casing one end sets up connecting thread other end and sets up connecting thread down, its characterized in that: be equipped with first oil pocket and the second oil pocket that the intercommunication set up in the casing, be provided with the pedestal between first oil pocket and the second oil pocket, the pedestal passes through limit structure and connects inside the casing, be equipped with at least a set of oil drain straight hole in the pedestal, the one end that the pedestal is close to the second oil pocket is provided with the spacing seat that the external diameter is less than the casing internal diameter, is provided with the spacing annular of V type between pedestal and the spacing seat, spacing annular is provided with at least a set of oil drain side opening with the straight hole intercommunication of oil drain, install the external diameter in the spacing annular and be less than the casing internal diameter and the sealing washer that the wire diameter is greater than oil.
Adopt above-mentioned technical scheme the utility model discloses the theory of operation does: when fluid flows to the first cavity from the second cavity, the fluid flows into the first cavity from the second cavity through the oil drainage straight hole, the oil drainage side hole and the sealing ring, and the fluid can be ejected from the sealing ring when flowing to the first cavity from the second cavity and enters the first cavity from the oil drainage side hole because the outer diameters of the sealing ring and the limiting table are smaller than the inner diameter of the valve body, and the fluid in the first cavity can not eject the sealing ring to return to the second cavity again, and the fluid in the first cavity can only extrude the sealing ring to enable the sealing ring to block the oil drainage side hole, so that the sealing ring type one-way valve is formed.
The seal ring type one-way valve can be further provided as follows: the limit structure is including the binding off annular that sets up on the casing, the pedestal is provided with the binding off in binding off annular department, be provided with seal structure between the both ends that the pedestal set up the binding off relatively and the casing respectively.
By adopting the technical scheme, the shell is arranged at the closing-up position of the seat body with the closing-up annular groove, the relative position of the shell and the seat body is fixed, and the closing-up position can be positioned in the middle of the seat body and also can be positioned at one end of the seat body close to the first cavity or one end of the seat body close to the second cavity.
The seal ring type one-way valve can be further provided as follows: the sealing structure comprises at least one mounting groove arranged on the base body, and a first sealing ring is mounted in the mounting groove.
By adopting the technical scheme, the number of the first sealing rings assembled at the two ends of the seat body can be one or more, the first sealing rings can be O-shaped sealing rings, Y-shaped sealing rings and other sealing rings, and the sealing rings can also be O-shaped sealing rings, Y-shaped sealing rings or other sealing rings.
The seal ring type one-way valve can be further provided as follows: the number of the oil drainage straight holes is 1 group.
The seal ring type one-way valve can be further provided as follows: the number of the oil drainage side holes is one group.
The seal ring type one-way valve can be further provided as follows: the number of the mounting grooves is two.
The utility model has the advantages that: simple structure, convenient installation and long service life.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
