Abstract

The utility model relates to a sealing ring. The inner side of the basal body of a sealing ring is provided with a projecting part, the projecting part comprises an end part and a root part connected with the basal body, the root part and a plane form an included angle of 120-140 degrees, the width of the end part is larger than that of the root part, and the end part is parallel to the plane. When the sealing ring is used and is extruded to deform, the projecting part can be extruded to deform, at the time, when very high pressure is acted on the projecting part, the pressure of liquid can be effectively overcome, the seepage of the liquid can be prevented, and very good sealing effect can be achieved.

Description

Seal ring

Technical field

The utility model relates to a kind of seal ring, particularly relates to a kind of seal ring that is used for the calorimeter sealing.

Background technique

The effect of seal ring is that fluid is mechanically sealed, traditional seal ring form has O RunddichtringO, X RunddichtringO and y-type seal ring etc., these seal rings mechanically play certain seal action, but for as calorimeter, this class of ultrasonic calorimeter for the extra high instrument of sealing requirements, the seal ring of conventional construction has not satisfied the sealing requirements of existing equipment, therefore, be badly in need of developing new structure seal ring with high sealing performance.

The model utility content

The technical problems to be solved in the utility model provides a kind of new structure seal ring with high sealing performance.

The utility model seal ring comprises the seal ring matrix, is provided with projection in the inboard of matrix, and projection comprises end and the root that is connected with matrix, and root becomes 120-140 ° of angle with horizontal plane.

The utility model seal ring, end width are greater than the root width, and described end is parallel with horizontal plane.

The utility model seal ring, the root of described projection preferably become 135 ° of angles with horizontal plane.

The utility model seal ring, the cross section of described matrix are circle, polygonal, rectangle or arch.

The utility model seal ring, the preferred arch in the cross section of described matrix.

Described seal ring is made by rubber material.

Described seal ring preferably uses on table meters such as calorimeter, ultrasonic calorimeter.

The beneficial effects of the utility model: difference from prior art is that the utility model seal ring is provided with projection in the inboard of matrix, seal ring is placed in the seal groove, when seal ring is squeezed distortion, the projection distortion that also can be squeezed, this moment, projection was subjected to very big pressure, can effectively overcome the pressure of liquid, stop oozing out of liquid, reach good sealing effect.

Description of drawings

Fig. 1 is the plan view of the utility model seal ring;

Fig. 2 is the A-A sectional drawing of Fig. 1;

Fig. 3 is a local enlarged diagram under the utility model seal ring user mode.

Embodiment

As shown in Figure 1, 2, the utility model seal ring comprises seal ring matrix 1, be provided with projection 2 in the inboard of matrix 1, projection 2 comprises end 3 and the root 4 that is connected with matrix 1, root 4 becomes 135 ° of angles with horizontal plane, end 3 width are greater than root 4 width, and end 3 is parallel with horizontal plane, the cross section of matrix 1 is an arch, and whole seal ring is made by rubber material.

As shown in Figure 3, seal ring is placed between the upper and lower covers 5,6 of calorimeter, fixedly tighten with screw, when seal ring is squeezed distortion, projection 2 distortion that also can be squeezed, and effectively be sealed into the line deformable seal, when fixedly tightening, upper and lower covers 5,6 usefulness screws can produce little distortion, effectively potted line is along little moving on the direction of projection 2, can effectively overcome the situation that causes the underpressure of primary sealing area that liquid is oozed out because of upper and lower covers 5,6 distortion this moment, reach good sealing effect.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.

Claims (5)
