Embodiment 1

[0006] Embodiment 1. A special rubber sealing ring for a pressure vessel of the present invention is a combined sealing ring, which combines the shapes of the U-shaped sealing ring and the O-shaped sealing ring, and is improved on this basis. The outer corner of the upper part of the annular body of the sealing ring is an O-ring shape R, that is, the outer corner of the annular body and the upper surface are rounded. The lower part of the annular body of the sealing ring is provided with a circle of V-shaped grooves A2 and A3, which are the part of the V-shaped groove. In this way, a rubber sealing ring similar to a V-shaped pressure vessel can be formed, and the direction of the V-shaped notch is toward the pressure-bearing part of the pressure vessel during assembly. In the case of low pressure, the O-ring part of the sealing ring can normally exert the good low-pressure sealing performance of the ordinary O-ring sealing ring. In the case of high pressure, the V-shaped notc...

Embodiment 2

[0009] Embodiment 2. A special sealing ring for a pressure vessel of the present invention is an elastic plastic annular body, and the outer side and the upper surface of the annular body are rounded, forming a part 11 similar to an O-shaped sealing ring; There is a right-angled triangular notch 13 in place. The lower part of the annular body of the sealing ring is provided with a V-shaped groove, and a V-shaped ring groove 2 is formed under the annular body. There is also a V-ring groove 4 in the middle of the outer surface. In this way, the elastic plastic sealing ring of the present invention is assembled in the annular groove between the main body 21 and the end cover 22 of the pressure vessel. The sealing performance makes up for the defect of insufficient sealing of these two kinds of sealing rings under high pressure and low pressure respectively. In addition, since the upper and lower parts of the sealing ring are provided with a triangular notch, the deformation spa...

Abstract

The special sealing ring for pressure vessels is an elastic annular body, with rounded corners between the outer side and the upper side of the annular body, forming a part similar to an O-shaped sealing ring; there is a ring groove on the bottom of the annular body, and There is an annular groove. The sealing ring of the present invention is assembled on the sealing end plate of the pressure vessel, and the direction of the ring groove opened under the sealing ring faces the pressure-bearing part of the pressure vessel. In the case of low pressure, the O-ring part of the sealing ring can normally exert low-pressure sealing performance. In the case of high pressure, since there is an annular groove under the sealing ring facing the pressure-bearing part of the pressure vessel, the outer side of the groove and the upper annular groove will be more closely attached to the sealing walls of the pressure vessel under high pressure, thus exerting excellent performance. High pressure sealing performance.

Description

Technical field: [0001] The special sealing ring for pressure vessel is a wake-up elastic sealing ring that is assembled on the sealing end plate (cover) of the pressure vessel and seals the seam between the main body of the pressure vessel and the sealing end plate or sealing cover. Background technique: [0002] The existing special sealing rings for pressure vessels are all annular bodies made of elastic materials. The cross-section of the annular body is a rectangular or circular or U-shaped sealing ring. The sealing ring of circular section is also called O-ring. The performance of these sealing rings is single, some are suitable for low pressure state, and some are suitable for high pressure state. However, during the working process of the pressure vessel, the pressure is constantly changing. Therefore, it is often possible to seal when the main body of the pressure vessel and the sealing end plate or the sealing cover are butted, but as the pressure increases, the ...
