Background

The U-ring is a sealing ring with symmetrical sealing lips for a single-acting or double-acting standard hydraulic cylinder of a piston rod or piston.

The existing sealing ring is generally sealed by elasticity or compulsory, and is easy to cause leakage when receiving ultrahigh pressure, or loses resilience under the condition of long-time compression, so that leakage is caused, time and labor are required to be replaced at regular time, and therefore, a high-pressure-resistant U-shaped sealing ring with good resilience is provided by a person skilled in the art so as to solve the problems in the background art.

Disclosure of Invention

The utility model aims to solve the defects in the prior art and provides an inner sealing U-shaped ring.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the inner sealing U-shaped ring comprises a sealing ring main body, wherein a steel spring is arranged in the sealing ring main body, a U-shaped groove is formed in the center of the upper end face of the sealing ring main body, and a U-shaped ring is arranged in the U-shaped groove;

through the technical scheme, the thrust expansion is obtained by means of the gas or fluid medium passing through the U-shaped inner part, and under the action of pressure, the higher the pressure is, the better the sealing effect is.

Further, the sealing ring main body is made of neoprene;

by the technical scheme, the chloroprene rubber has strong corrosion resistance and temperature resistance.

Further, the steel spring is made of an X750 special steel spring;

through the technical scheme, the supporting resilience force is strong.

Further, positioning protrusions are arranged on the inner sides of the upper end and the lower end of the U-shaped ring;

through above-mentioned technical scheme, the location arch can be used to fixed sealing washer main part be difficult for droing.

Further, the positioning protrusion and the U-shaped groove are integrally formed;

through the technical scheme, the novel plastic composite material is not easy to deform.

The utility model has the following beneficial effects:

1. in the utility model, the thrust expansion is obtained by means of the gas or fluid medium passing through the U-shaped inside, and the higher the pressure is, the better the sealing effect is.

2. In the utility model, the sealing ring main body is provided with the steel spring, the supporting resilience force is enhanced, and the selected chloroprene rubber and X750 special steel spring is used for various ultralow-temperature and high-corrosion severe working condition media.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, one embodiment provided by the present utility model is: the utility model provides an inner seal U-shaped circle, includes sealing washer main part 1, and sealing washer main part 1 inside is provided with steel spring 3, and U-shaped groove 2 has been seted up to sealing washer main part 1 up end center department, and U-shaped groove 2 inside is provided with U-shaped circle 4, and steel spring 3 selects X750 idiosyncratic steel spring, and is small, supports the resilience force strong, can be used to some high strength pressure seal circle, and the pressure is bigger, and the sealed effect is better.

The sealing washer main part 1 material is chloroprene rubber, and chloroprene rubber has very strong corrosion resistance and temperature resistance, and steel spring 3 material is X750 idiosyncratic steel spring, and it is strong to support the resilience force, and the upper and lower end inboard all is equipped with location arch 5 on the U-shaped circle 4, and location arch 5 can be used to fixed sealing washer main part 1 be difficult for droing, and location arch 5 and U-shaped groove 2 are integrated into one piece, and when the pressure was great, non-deformable.

Working principle: the inner sealing U-shaped ring is formed by adding the steel spring 3 in the sealing ring main body 1, so that the whole supporting resilience force is enhanced, and meanwhile, gas or fluid media are expanded by virtue of the thrust force when the U-shaped groove 2 in the sealing ring main body 1, under the action of pressure, the higher the pressure is, the better the sealing effect is, and the inner sealing U-shaped ring can be used for various ultralow-temperature and high-corrosion harsh working condition media.

Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
