Description
Technical Field
The utility model relates to an ultrahigh pressure cleaning technical field specifically is an ultrahigh pressure combined sealing structure.
Background
Need pressurize water when carrying out the superhigh pressure washing, then spout through the pipeline, need increase seal structure between the pipe joint and guarantee water pressure, avoid leaking.
The sealing ring is usually adopted in the existing sealing mode, a groove for placing the sealing ring needs to be processed in one of the holes, but the sealing bearing pressure of the sealing ring is low, so that the service life of the sealing ring is short, the water leakage phenomenon frequently occurs, frequent replacement is needed, and the sealing ring is clamped in the groove and can be squeezed into a matching gap by high-pressure water, so that the sealing ring is damaged, and the sealing effect is not ideal.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to overcome current defect, provide an superhigh pressure combined seal structure, can improve sealed bearing performance, increase of service life increases the sealing reliability, can effectively solve the problem in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an superhigh pressure combination seal structure, includes that first joint and second connect, the front end that first joint is provided with the step axle, and the medial surface that the second connects is provided with the step hole, the step axle cooperation of first joint is pegged graft at the step hole that the second connects, the step off-axial side of first joint has cup jointed seal assembly, seal assembly includes elasticity soft circle and hard circle, the hard circle cup joints the one end at elasticity soft circle, the inside wall in step hole is all hugged closely to the lateral surface of elasticity soft circle and hard circle.
As an optimized technical scheme of the utility model, the polyurethane sealing washer is chooseed for use to the soft circle of elasticity.
As an optimized technical scheme of the utility model, the peek sealing washer is chooseed for use to the hard circle.
As an optimized technical scheme of the utility model, the tip lateral surface of step axle is the toper face, and the terminal surface of step axle is the plane.
As an optimized technical proposal of the utility model, the outer side surface of the elastic soft ring is a conical surface.
As an optimized technical scheme of the utility model, be connected through the pressfitting mode between soft circle of elasticity and the hard circle.
Compared with the prior art, the beneficial effects of the utility model are that: this superhigh pressure combined seal structure reasonable in design, the installation of being convenient for, can two sealing reliability who connects of effectual improvement, through directly cup jointing seal assembly at the lateral surface of step axle, need not to process the recess, the process flow has been saved, the laminating of the flexible circle of elasticity in the seal assembly and the medial surface in step hole, the flexible circle of elasticity has elasticity, can take place the inside wall in deformation laminating step hole more under hydraulic extrusion, the bearing capacity has been improved, simultaneously through setting up the fixed flexible circle that the hard circle can be better, improve the effect that compresses tightly of the flexible circle of elasticity, the convenience in use has been improved greatly.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example 1: referring to fig. 1-4, the present invention provides a technical solution: an ultrahigh pressure combined sealing structure comprises a first joint 1 and a second joint 2, wherein a step shaft 4 is arranged at the front end of the first joint 1, a step hole 3 is arranged on the inner side surface of the second joint 2, the step shaft 4 of the first joint 1 is matched and inserted in the step hole 3 of the second joint 2, the end surface of the step shaft 4 is a plane, a sealing component 5 is sleeved on the outer side surface of the step shaft 4 of the first joint 1, the sealing component 5 comprises an elastic soft ring 51 and a hard ring 52, the elastic soft ring 51 is a polyurethane sealing ring, the hard ring 52 is a peek sealing ring, the outer side surface of the end part of the step shaft 4 is a conical surface, the sealing component is conveniently and better clamped on the surface of the step shaft 4, the hard ring 52 is sleeved at one end of the elastic soft ring 51, the elastic soft ring 51 is connected with the hard ring 52 in a pressing mode, the connection stability between the elastic soft ring 51 and the hard ring 52 is ensured, the outer side surfaces of the elastic soft ring 51 and the hard ring 52 are tightly attached to the inner side wall of the step hole 3, the ultrahigh pressure combined sealing structure is reasonable in design and convenient to install, can effectively improve the sealing reliability of the two joints, and prolongs the service life of the sealing assembly.
When in use: firstly, the hard ring 52 is pressed at one end of the elastic soft ring 51, then the elastic soft ring 51 and the hard ring 52 are sleeved on the outer side surface of the step shaft 4, the step shaft 4 is pressed into the step hole 3 of the other joint structure, when the high-pressure water is passed through, the high-pressure water is applied to the step shaft, the hard ring 52 extrudes the elastic soft ring 51, the elastic soft ring 51 is tightly attached to the inner side wall of the step hole 3, meanwhile, the elastic soft ring 51 has certain elasticity, the inner side wall of the step hole 3 can be better attached to the installation, and the sealing effect is improved.
