Description

Rubber sealing film of gas storage cabinet

Technical Field

The utility model relates to a gas storage holder technical field especially relates to a gas storage holder rubber seal membrane.

Background

The gas holder is a container for storing low-pressure gas. For relieving imbalance between supplied air quantity and used air quantity. There are wet and dry methods. The lower drawing is a schematic diagram of a spiral gas holder, which is a wet gas holder widely used. It is composed of water tank, bell jar, tower section, water seal, guide track, platform, top frame, top plate and gas inlet and outlet pipeline. According to the amount of air in the gas cabinet, the guide rails on the wall plate and the guide wheels arranged on the platform move relatively, so that the tower section rotates to ascend or descend, and the gas storage volume of the gas cabinet is changed within a certain range. The dry gas storage cabinet is similar to an internal floating roof oil tank in structure, and has low use because the piston (equivalent to a floating roof) and the cabinet wall need to flexibly slide relative to each other and have excellent sealing performance, thus having high requirements on the construction quality of the cabinet body, the piston and other parts. The maximum storage cabinet volume in the world reaches 34 ten thousand m 3. The gas storage cabinet works under low pressure, the gas storage amount per unit volume is small, and the gas storage efficiency is low. The spherical tank and the horizontal tank with high pressure resistance can be used for storing gas under medium pressure, and the tube bundle consisting of the steel tubes can be used for storing high-pressure gas, so that the gas storage efficiency is improved;

the gas holder is because need stretch out and draw back, consequently, needs the rubber seal membrane to seal, but current rubber seal membrane is when using, because the gas holder is bulky, leads to sealed effect relatively poor.

Therefore, it is necessary to provide a rubber sealing film for a gas holder to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a gas storage holder rubber seal membrane.

The utility model provides a pair of gas holder rubber seal membrane, including the rubber ring, rubber ring lower surface outer fringe is fixed with first sealed limit, rubber ring upper surface inner edge is fixed with the second sealed limit, the inside air cavity of having seted up of rubber ring, hidden groove has been seted up to rubber ring top one end, it inlays in the middle part of the hidden groove and is fixed with the charging connector, and charging connector bottom and air cavity intercommunication.

Preferably, the rubber ring is provided with grooves at the junction of the first sealing edge and the second sealing edge at equal intervals.

Preferably, the rubber ring is integrally formed with the first sealing edge and the second sealing edge.

Preferably, the first sealing edge and the second sealing edge are arranged obliquely.

Preferably, a reinforced steel plate is fixed in the middle of the inflating nozzle and is fixedly connected with the rubber ring.

Preferably, the rubber ring is internally compounded with a steel wire.

Compared with the prior art, the utility model provides a gas holder rubber seal membrane has following beneficial effect:

the utility model provides a gas holder rubber seal membrane:

after the rubber ring is installed, can aerify the air cavity of rubber ring inner wall through the charging connector, make gas can outwards strut the rubber ring, make rubber ring volume increase, thereby improve the compactness of rubber ring and installation face, improve sealed effect, and first sealed limit and the second sealed limit that set up on the rubber ring then have certain atmospheric pressure in the gas holder under the condition, can extrude first sealed limit and the sealed limit of second and move to one side, further improve the leakproofness, the recess of seting up on the rubber ring can make things convenient for buckling of first sealed limit and second sealed limit.

Drawings

Fig. 1 is a schematic sectional view of the present invention.

Reference numbers in the figures: 1. a rubber ring; 2. a first sealing edge; 3. a second sealing edge; 4. an air cavity; 5. hiding the groove; 6. an air charging nozzle; 7. a groove; 8. and reinforcing the steel plate.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

In the specific implementation process, as shown in fig. 1, a rubber sealing film of a gas storage holder comprises a rubber ring 1, a steel wire is compounded in the rubber ring 1, a first sealing edge 2 is fixed on the outer edge of the lower surface of the rubber ring 1, a second sealing edge 3 is fixed on the inner edge of the upper surface of the rubber ring 1, a gas cavity 4 is formed in the rubber ring 1, a hidden groove 5 is formed in one end of the top of the rubber ring 1, an inflating nozzle 6 is embedded and fixed in the middle of the hidden groove 5, the bottom of the inflating nozzle 6 is communicated with the gas cavity 4, after the rubber ring 1 is installed, the gas cavity 4 on the inner wall of the rubber ring 1 can be inflated through the inflating nozzle 6, the inflated gas is nitrogen, the nitrogen has certain stability and small thermal expansion and cold contraction, so that the gas can outwards expand the rubber ring 1, the volume of the rubber ring 1 is increased, and the tightness between the rubber ring 1 and an installation surface is improved, the sealing effect is improved.

Referring to fig. 1, rubber ring 1 is located the juncture equidistance of first sealed limit 2 and second sealed limit 3 and sets up fluted 7, rubber ring 1 is the integrated into one piece setting with first sealed limit 2 and second sealed limit 3, first sealed limit 2 and second sealed limit 3 are the slope setting, and first sealed limit 2 and second sealed limit 3 that set up on rubber ring 1 then have under the condition of certain atmospheric pressure in the gas holder, can extrude first sealed limit 2 and second sealed limit 3 to the motion on one side, further improve the leakproofness, and recess 7 of seting up on rubber ring 1 can make things convenient for buckling of first sealed limit 2 and second sealed limit 3.

Referring to fig. 1, a reinforced steel plate 8 is fixed in the middle of the charging connector 6, and the reinforced steel plate 8 is fixedly connected with the rubber ring 1, so that the structural strength of the rubber ring 1 at one end of the charging connector 6 is improved.

The working principle is as follows:

after rubber ring 1 is installed, can aerify air cavity 4 of 1 inner wall of rubber ring through charging connector 6, make gas can outwards strut rubber ring 1, make 1 increase in size of rubber ring, thereby improve the compactness of rubber ring 1 and installation face, improve sealed effect, and first sealed limit 2 and the sealed limit 3 of second that set up on rubber ring 1 then have under the condition of certain atmospheric pressure in the gas holder, can extrude first sealed limit 2 and the sealed limit 3 of second and move to one side, further improve the leakproofness, recess 7 of seting up on the rubber ring 1 can make things convenient for buckling of first sealed limit 2 and the sealed limit 3 of second.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
