Description

TECHNICAL FIELD

[0001] The utility model relates to sealing technical field, concretely is a kind of steam autoclave leakproof sealing ring. BACKGROUND

[0002] Steam autoclave is also called steam curing autoclave and pressure steam autoclave, which is a large pressure vessel with large volume and heavy weight. The steam autoclave is a large pressure vessel. During use, the pressure in the autoclave is very large, and the cover is the most commonly used part, so it is also the most prone to problems. The existing steam autoclave sealing is composed of a rubber sealing ring, a stop valve, and a steam inlet elbow. The rubber sealing ring is embedded in the flange sealing groove of the autoclave body. During operation, the sealing steam enters the sealing groove, making the sealing ring tightly adhere to the end face of the cover, thereby achieving the sealing effect.

[0003] The applicant found that a "leak-proof connection sealing ring" was disclosed in Chinese Patent Publication No. CN200943784Y. This patent mainly achieves sealing effect through the friction force between the column ring and the sealing ring. However, the size of the sealing ring and the interface is the same, and it is difficult to install the sealing ring due to the friction force. Therefore, we propose a steam autoclave leakproof sealing ring. SUMMARY

[0004] The utility model aims at providing a steam autoclave leakproof sealing ring.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a steam autoclave leakproof sealing ring, comprising a steam autoclave main body, the upper end face of the steam autoclave main body is overlapped with a cover plate, the side face of the cover plate is sealingly connected with a sealing ring main body, the side face of the sealing ring main body is sealingly connected with the inner wall of the steam autoclave main body, the inner wall of the sealing ring main body is provided with a cavity, and the symmetric two sides of the sealing ring main body are fixedly connected with supporting rings.

[0006] As a further scheme of the utility model: the material of the sealing ring main body is set as high-viscosity and high-toughness silica gel, and the material of the supporting ring is the same as that of the sealing ring main body.

[0007] As a further scheme of the utility model: the side face of each supporting ring is abutted against the inner wall of the steam autoclave main body.

[0008] As a further scheme of the utility model: the number of supporting rings is set as six, and the side face of each supporting ring is abutted against the inner wall of the steam autoclave main body.

[0009] As a further scheme of the utility model: the outer diameter of the sealing ring main body matches the diameter of the inner wall of the steam autoclave main body, and the inner diameter of the sealing ring main body matches the diameter of the side wall of the cover plate.

[0010] As a further scheme of the utility model: the shape of the side surface of the sealing ring body is set as an isosceles trapezoid, and the angle between the side wall of the sealing ring body and the lower end surface is set as 100°.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] 1、The side surface of the sealing ring body is set as an isosceles trapezoid, so that the contact surface between the sealing ring body and the autoclave body is small when being installed, the friction force is small, and the sealing ring body can be conveniently installed in the cover plate and the autoclave body by the staff.

[0013] 2、The sealing ring body can be expanded and deformed by the pressure of the sealing gas, a new seal is formed at the sealing gap part, so that the automatic compensation sealing effect is realized, and the sealing property of the autoclave body is improved.

[0021] The specific embodiments of the utility model will be further described in combination with the drawings, and it needs to be explained here that the description of these embodiments is used to help understanding the utility model, but does not constitute the limitation to the utility model.

[0022] In addition, the technical features involved in each of the embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please refer to the attached Figure 1 -attached Figure 5 The utility model relates to a steam pressure still leakproof sealing ring, including steam pressure still main part 1, the upper end surface of steam pressure still main part 1 is overlapped and is covered with the plate 2, the side surface of the plate 2 is sealedly connected with sealing ring main part 3, the inner wall of sealing ring main part 3 is sealedly connected with the inner wall of steam pressure still main part 1, the inner wall of sealing ring main part 3 is equipped with cavity 4, the symmetrical both sides of sealing ring main part 3 are fixedly connected with support ring 5, support ring 5 can improve the resilience of sealing ring main part 3, prevent sealing ring main part 3 from being unable to carry out normal resilience after repeated use, steam pressure still main part 1 and the side surface of the plate 2 are fixedly connected with fixed block 6, the fixed block 6 is screwedly connected with threaded rod, the number of support ring 5 is set to six, the side surface of each support ring 5 is all abutted in the inner wall of steam pressure still body, the outer ring diameter of sealing ring main part 3 matches the diameter of the inner wall of steam pressure still main part 1, the inner ring diameter of sealing ring main part 3 matches the diameter of the side wall of the plate 2.

[0024] In example one, the material of sealing ring main part 3 is set to high-viscosity and high-toughness silica gel, and the material of support ring 5 is the same as that of sealing ring main part 3.

[0025] Specifically, sealing ring main part 3 and support ring 5 use the same material, which can be conveniently formed in one step during production. Meanwhile, the use of high-viscosity and high-toughness silica gel can enable sealing ring main part 3 to normally rebound after repeated use, thereby improving the service life of sealing ring main part 3.

[0026] In example two, the shape of the side surface of sealing ring main part 3 is set to isosceles trapezoid, and the angle between the side wall and the lower end surface of sealing ring main part 3 is set to 100°.

[0027] Specifically, the trapezoidal shape can reduce the contact area between sealing ring main part 3 and the inner wall of steam pressure still main part 1, which can facilitate the combination of the plate 2 with sealing ring main part 3 on steam pressure still main part 1. When the pressure in steam pressure still main part 1 increases, the high-pressure gas will extrude the cavity 4 in sealing ring main part 3, so that the inclined plate of sealing ring main part 3 is extruded to both sides, which can drive support ring 5 to abut against the side wall of steam pressure still main part 1 and the plate 2, thereby realizing the sealing between steam pressure still main part 1 and the plate 2.

[0028] Working principle:

[0029] Firstly, the staff can sleeve the sealing ring body 3 on the side wall of the cover plate 2, then the staff combines the cover plate 2 on the autoclave body 1, and the cover plate 2 is limited by screwing the threaded rod in the fixing block 6, when the autoclave body 1 works and the internal pressure increases, the high-pressure gas in the autoclave body 1 presses the cavity 4 in the sealing ring body 3, the cavity 4 is compressed and the side of the sealing ring body 3 drives the supporting ring 5 to abut against the side wall of the autoclave body 1 and the cover plate 2, so that the sealing between the autoclave body 1 and the cover plate 2 can be realized, in the pressure meeting interval, the greater the pressure in the autoclave body 1, the greater the extrusion strength of the cavity 4, and the connection between the sealing ring body 3 and the autoclave body 1 is more closely, after the pressure in the autoclave body 1 reaches normal atmospheric pressure after work, the cavity 4 returns to the original state, the sealing ring body 3 and the autoclave body 1 are separated, and the cover plate 2 can be conveniently taken down, thus, the whole working process is completed.

[0030] The above front, rear, left, right, up and down are based on the drawings of the specification Figure 1 As a standard, the side of the device facing the observer is defined as front, the left side of the observer is defined as left, and so on.
