Description

Check valve sealing ring

Technical Field

The utility model belongs to the technical field of the valve seal technique and specifically relates to a check valve sealing washer.

Background

The check valve is a valve that automatically opens and closes a valve flap depending on the flow of a medium itself to prevent the backflow of the medium, and is also called a check valve, a back-flow valve, and a back-pressure valve. The check valve is an automatic valve and mainly used for preventing medium from flowing backwards, preventing the pump and a driving motor from reversing and discharging container medium. Check valves may also be used to provide a line to replenish auxiliary systems in which the pressure may rise above the system pressure. The check valve can be mainly divided into a swing check valve and a lift check valve.

In order to promote the sealed effect of check valve, all can set up the sealing washer on the contact surface of check valve, traditional sealing washer simple structure produces the displacement easily under frequent on-off state, because cross-sectional structure is mostly circular structure moreover, leads to its inside resistance that produces easily, makes its stability not high.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem existing in the background art, the utility model provides a check valve sealing ring.

The utility model provides a check valve seal circle, sealing washer body including rubber material, inside the extrusion cavity of having seted up of sealing washer body, sealing washer body lateral surface on set up the side direction trompil that is linked together with in the extrusion cavity of inside, sealing washer body outside arcwall face on have a body structure go-between, go-between lateral surface border position have the outside cyclic annular arch of a body structure that is used for promoting assembly firmness and stability, the sealing washer body keep away from the assembly face and be the conical surface.

Preferably, the lateral opening hole is in an inclined layout, and the lower end of the side surface of the sealing ring body, which is located at the opening position of the lateral opening hole, is provided with an integrated flow guide ring.

Preferably, the lower surface of the sealing ring body is provided with an annular assembling groove.

Preferably, the inner side surface of the annular assembling groove is provided with a necking ring in an integral structure at the position of the lower end opening.

Preferably, the anti-bending ring made of PVC is inserted inside the annular assembly groove and positioned on the inner side of the necking ring.

Preferably, the edge position of the upper end of the sealing ring body is provided with an annular extrusion groove.

The utility model discloses a check valve sealing ring, adopt the design of built-in inside extrusion cavity, can make its adjustable structure according to the external structure of automatic adjustment of on-off state, promote the laminating nature under the closed state and reduce the lateral resistance under the on-off state; the outer side arc-shaped surface of the sealing ring body is provided with a connecting ring with an outer annular bulge arranged on the side, and the connecting ring is matched with an anti-bending ring in the annular assembling groove, so that the firmness and the limiting capability of an assembling position can be improved.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention in an open state of the check valve.

Fig. 2 is a schematic structural diagram of the present invention in a closed state of the check valve.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 and fig. 2 show a check valve seal ring, including rubber's sealing washer body 1, inside extrusion chamber 2 has been seted up to sealing washer body 1 inside, set up on the sealing washer body 1 lateral surface with inside extrusion chamber 2 in the side direction trompil 3 that communicates, a body structure go-between 4 has on the 1 outside arcwall face of sealing washer body, go-between 4 lateral surface border position has the outside cyclic annular arch 5 of a body structure that is used for promoting assembly firmness and stability, sealing washer body 1 is kept away from the assembly face and is the conical surface.

In order to reduce the resistance of the incident flow surface and promote the negative pressure to exhaust, the lateral opening 3 is in an inclined layout, and the lower end of the side surface of the sealing ring body 1, which is positioned at the opening position of the lateral opening 3, is provided with an integral structure flow guide ring 6.

In order to match bottom assembly, the lower surface of the sealing ring body 1 is provided with an annular assembly groove 7.

In order to improve the bottom looseness prevention, the inner side surface of the annular assembling groove 7 is provided with a necking ring 8 of an integral structure at the lower end opening position.

In order to improve the deformation resistance of the bottom assembly surface, an anti-bending ring 9 made of PVC is inserted inside the annular assembly groove 7 and positioned on the inner side of the reducing ring 8.

In order to facilitate inward deformation after extrusion, an annular extrusion groove 10 is formed in the edge position of the upper end of the sealing ring body 1.

The utility model discloses a check valve sealing ring, adopt the design of built-in inside extrusion cavity 2, can make its structure adjustable according to its external structure of automatically regulated of on-off state, promote the laminating nature under the closed state and reduce the lateral resistance under the on-off state; the connecting ring 4 with the external annular bulge 5 arranged on the side is arranged on the outer arc-shaped surface of the sealing ring body 1, and meanwhile, the anti-bending ring 9 in the annular assembling groove 7 is matched, so that the firmness and the limiting capacity of the assembling position can be improved.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
