Description
Technical Field
The utility model relates to a sealing member technical field, in particular to novel super high pressure water pump end face seal circle.
Background
At present, the traditional ultrahigh pressure water pump end face seal adopts a butyl blue rubber O-shaped ring or a polyurethane O-shaped ring as end face seal, along with the improvement of market to the ultrahigh pressure water pump pressure grade, higher requirements are also put forward to the end face seal piece simultaneously, the existing ultrahigh pressure water pump end face seal in the market is up to 200Mpa pressure, the market requirements can not be met by using the traditional O-shaped ring, and the phenomena of extrusion, tearing, hardening and the like often appear by adopting the O-shaped ring.
SUMMERY OF THE UTILITY MODEL
In view of the above, an object of the present invention is to provide a novel ultra-high pressure water pump end face seal ring that uses higher pressure, can effectively prevent the sealing ring end face from extruding.
In order to realize the purpose, the technical scheme of the utility model is that:
the utility model provides a novel super high pressure water pump end face seal circle, a serial communication port, including sealing ring and triangle retaining ring, the sealing ring inboard is equipped with U type notch, the inboard one end corner of sealing ring is equipped with the chamfer angle, the corner of the inboard other end of sealing ring is equipped with side V-arrangement bellying, sealing ring outside terminal surface is equipped with the inclined plane breach, the triangle retaining ring is connected on the inclined plane breach.
Further, the side vertex of the side V-shaped convex part is a first sealing point, and the upper end point of the chamfer angle is a second sealing point.
Further, the section of the triangular check ring is a right-angled triangle.
Further, the sealing ring is a sealing ring made of polyurethane material.
Further, the triangular check ring is made of polyformaldehyde.
The utility model has the advantages that: the sealing ring receives the medium pressure effect, and the sealing ring is removed by the internal diameter to the external diameter, and the triangle retaining ring is lifted up simultaneously, has filled the clearance position that has increaseed and has prevented that the sealing ring from extruding toward the clearance position to successfully prevent that the sealing ring from extruding, U type notch is opened by the extrusion, extrudeed at chamfer and side V-arrangement bellying and forms sealed chamber, successfully sealed preventing medium outflow, has increased sealing ring compressive capacity and sealing performance by a wide margin.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figures, 10-sealing ring; 11-U-shaped notches; 12-chamfering; 13-side V-shaped projections; 14-bevel gap; 15-first sealing point; 16-a second sealing point; 20-triangular check ring.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the novel ultra-high pressure water pump end face seal ring comprises a seal ring 10 and a triangular retainer ring 20. Wherein, sealing ring 10 is made for the polyurethane material of hardness shore D57 degree, and sealing ring 10 chooses for use the difficult sclerosis of polyurethane material, and the resilience is good, and triangle retaining ring 20 is made for shore D82's polyformaldehyde material, and is sealed effectual, prevents effectively that sealing ring 10 from receiving the high pressure to extrude, improves sealing washer life.
A U-shaped notch 11 is arranged on the inner side of the sealing ring 10, a chamfer 12 is arranged at one end corner of the inner side of the sealing ring 10, a second sealing point 16 is arranged at the upper end point of the chamfer 12, a side V-shaped bulge 13 is arranged at the other end corner of the inner side of the sealing ring 10, a first sealing point 15 is arranged at the side top point of the side V-shaped bulge 13, and an inclined plane notch 14 is arranged on the outer side end face of the sealing ring 10; the section of the triangular check ring 20 is a right triangle, and the triangular check ring 20 is connected to the inclined plane gap 14 in a matching way.
When the ultrahigh pressure water pump works, the sealing ring 10 is under the action of medium pressure, the sealing ring 10 moves from inner diameter to outer diameter, the U-shaped groove opening 11 is extruded and opened, and the first sealing point 15 and the second sealing point 16 are extruded up and down to form a sealing cavity, so that the medium is successfully sealed and prevented from flowing outwards;
sealing washer 10 receives about the extruded power that has an outside footpath in the time, 11 terminal surfaces of U type notch and bottom surface receive sealing ring 10 extrusion upper and lower tensile, the valve gap increases, sealing ring 10 is owing to receive the extruded power of pressurized outside footpath simultaneously, the terminal surface external diameter can move to valve gap clearance position, sealing ring 10 and the oblique 20 triangle cooperations of retaining ring, sealing ring 10 receives the extrusion and lifts up, triangle retaining ring 20 is lifted up simultaneously, polyformaldehyde retaining ring high strength pressure resistance, filled the clearance position that increases and prevented sealing ring 10 and extrude toward clearance position, thereby successfully prevent that sealing ring 10 from extruding, sealing ring 10 compressive capacity and life have been improved by a wide margin, service pressure can reach 200Mpa, allow more to extrude the terminal surface clearance simultaneously.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
