Description

TECHNICAL FIELD

[0001] The utility model relates to container sealing rubber strip technical field, especially a split pressure vessel sealing rubber strip. BACKGROUND

[0002] The use scene of the existing sealing rubber strip or sealing ring is generally that two containers or components extrude the sealing rubber strip from each other, so that the gap between the two containers or components can be sealed, and the situation of air permeation or water permeation does not occur, but the sealing ring sealing mode needs to rely on the extrusion of the sealing ring or the sealing rubber strip by external force, so a relatively firm external locking device is needed, and after the locking device is locked after installation, sealing can be realized, and the sealing ring and the sealing rubber strip cannot realize self-locking and reinforced sealing.

[0003] Therefore, the prior art still needs to be improved. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a split pressure vessel sealing rubber strip, and aims at solving the technical problems that the sealing rubber strip cannot realize self-locking with the rubber strip groove and reinforced sealing.

[0005] In order to realize the above-mentioned purpose, the technical scheme of the utility model is as follows: a split pressure vessel sealing rubber strip, which comprises a rubber strip main body, the bottom of the rubber strip main body is provided with a gas groove for facilitating the flow of gas, the lower end of the rubber strip main body is provided with two inverted grooves which are inclined outward, and the top of the rubber strip main body is provided with a lip on each side for sealing the upper container.

[0006] The split pressure vessel sealing rubber strip, wherein the included angle between the lip and the horizontal plane is 20-50°.

[0007] The split pressure vessel sealing rubber strip, wherein the length of the lip is 16-25mm.

[0008] The split pressure vessel sealing rubber strip, wherein the outward inclination angle of the inverted groove relative to the vertical line is 45-60°.

[0009] The split pressure vessel sealing rubber strip, wherein the depth of the inverted groove is 7-10mm.

[0010] The split pressure vessel sealing rubber strip, wherein the rubber strip main body is in the shape of a circle.

[0011] Beneficial effects: the utility model is installed in the rubber strip groove, the rubber strip is lifted through the inflation of the bottom gas groove, the container cavity is inflated, the two inverted grooves of the rubber strip are tightly attached to the rubber strip groove and reinforced sealing under the pressure in the cavity, self-locking sealing is realized, and the sealing of the cavity is ensured.

[0018] In order to make the purpose, technical scheme and advantages of the utility model more clear and definite, the following refers to the drawings and takes examples to further explain the utility model in detail.

[0019] As Figures 1-5 shown, the utility model discloses a split pressure vessel sealing rubber strip, it includes: rubber strip main body 1, the bottom of rubber strip main body 1 is equipped with the air groove 2 that facilitates flowing gas, the lower end both sides of rubber strip main body 1 are equipped with the open inclined outward inverted groove 3, the top both sides of rubber strip main body 1 are equipped with the lip 4 for sealing upper container respectively.

[0020] Preferably, the included angle formed by the lip 4 and horizontal plane is 20-50 °.

[0021] Preferably, the length of the lip 4 is 16-25 mm.

[0022] Preferably, the outward inclination angle of the inverted groove 4 relative to the vertical line is 45-60 °.

[0023] Preferably, the depth of the inverted groove 3 is 7-10 mm, and the length of the inverted groove lip 5 of the inverted groove 3 is 9 mm.

[0024] In one of the embodiments, the rubber strip main body 1 is in a circular shape.

[0025] As Figure 6 shown, the utility model is made into sealing ring 30, the sealing ring 30 is installed in the rubber strip groove of the lower cavity 20 of static pressure cavity; Figure 2 is the pressure receiving schematic view of the utility model;When installing, the specific operation is as follows:

[0026] ​​1. The upper cavity 10 is lowered, and the sealing ring seals the upper cavity 6 contact part with the upper double lip.

[0027] 2. The cavity is pressurized to 1.6Mpa, and the sealing ring inverted groove lip is tightly attached to the rubber strip groove of the lower cavity 20 to realize the groove sealing.

[0028] 3. The greater the cavity pressure, the tighter the sealing ring lip is attached to the upper cavity, and the tighter the sealing ring inverted groove lip is attached to the rubber strip groove of the lower cavity, thereby realizing the self-locking function.

[0029] The utility model is suitable for split type pressure vessel sealing.

[0030] The utility model is installed in the rubber strip groove, is lifted through the bottom inflatable rubber strip, the cavity is inflated, and the two inverted groove openings of the rubber strip are tightly attached to the rubber strip groove under the pressure in the cavity to reinforce the sealing. Thus, the sealing of the cavity is ensured. The utility model realizes the effect of pressure self-locking sealing, and after realizing the self-locking, the bottom of the rubber strip does not need to be inflated.

[0031] The above is the preferred embodiment of the utility model, and of course, cannot be used to limit the right scope of the utility model, and it should be pointed out that for the technical personnel in the technical field, the modification or equivalent replacement of the technical scheme of the utility model without creative labor does not deviate from the protection scope of the technical scheme of the utility model.
