Description
Technical field
The utility model is related to a kind of sealing means of pressure vessel, belongs to storage facilities field.
Background technology
Pressure vessel refers to filling gas or liquid and carries the Sealing Arrangement of certain pressure.Current pressure vessel is most
It is that the mode of being tightly connected has a variety of by being tightly connected realization sealing between lid and container.Simplest is directly in lid
Extruding sets one layer of rubber gasket between body and container, and this inside configuration storage gas or liquid can not have harmfulness.
For the sealing of this kind of gas or liquid, existing sealing structure many times can not can not all meet demand, in the short time
Interior sealing is perhaps effective, but if overlong time, then the danger of leakage, and stored gas or liquid strain occurs
Class is all very restricted.
Utility model content
The purpose of this utility model is that provides a kind of sealing means of pressure vessel to solve the above problems.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of sealing means of pressure vessel, including tank body, the tank body are provided with inner cap body and outer cover, the tank body

Inner top surface between connected by the spring, the tank mouth of the tank body is flared structure, and the cover plate is and the tank body
The frustum cone structure that matches of tank mouth, an air cavity is formed between the outer cover and the inner cap body, the outer cover is set
There is the valve connected with the air cavity.
Preferably, the cylinder is plastics barrel structure, the large-diameter portion lateral surface of the cylinder and the inner side of the outer cover
Face is fitted, and the upper end of the cylinder is contacted with the inner top surface of the outer cover.
Preferably, the outer cover be provided with lead to the air cavity fill bleeder port and air pressure detection hole, the valve peace
Filled mounted in described at bleeder port, air gauge is provided with the air pressure detection hole.
Preferably, the spring has two, and two springs are in extended state.
Preferably, it is provided with rubber seal between the tank mouth of the cover plate and the tank body.
The beneficial effects of the utility model are：
The utility model is using inside and outside lid sealing structure, sealing structure, outer cover between inner cap body and tank body tank mouth
Sealing structure between tank flange ensure that dual good sealing effectiveness, and sealing is formed between inner cap body and outer cover
Air cavity, can be sealed, so as to reach absolute sealing, total has by adding inert gas into the air cavity
Better seal performance, it is adaptable to long-time sealed storage, increases storage gas or liquid range to a certain extent.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- tank bodies, 2- ring flanges, 3- rubber gaskets, 4- bolts, 5- outer covers, 6- valves, 7- fills bleeder port,
8- springs, 9- air gauges, 10- air pressure detection holes, 11- cylinders, 12- cover plates, 13- rubber seal.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, the utility model includes tank body 1, tank body 1 is provided with inner cap body and outer cover 5, the port of tank body 1
Place is provided with ring flange 2, and outer cover 5 is connected with the ring flange 2 of tank body 1 by bolt 4, is set between outer cover 5 and ring flange 2
There is rubber gasket 3, inner cap body includes the cylinder 11 of cover plate 12, spring 8 and hierarchic structure, and the cascaded surface of cylinder 11 is pressed in rubber
On sealing gasket 3, the lower end of cover plate 12 and cylinder 11 is tightly connected, and is connected between the inner top surface of cover plate 12 and outer cover 5 by spring 8
Connect, the tank mouth of tank body 1 is flared structure, cover plate 12 is the frustum cone structure matched with the tank mouth of tank body 1, outer cover 5 with it is interior
An air cavity is formed between lid, outer cover 5 is provided with the valve 6 connected with air cavity.
Cylinder 11 is plastics barrel structure, and the large-diameter portion lateral surface of cylinder 11 is fitted with the medial surface of outer cover 5, cylinder 11
Upper end is contacted with the inner top surface of outer cover 5.
Outer cover 5 be provided with lead to air cavity fill bleeder port 7 and air pressure detection hole 10, valve 6, which is arranged on, fills bleeder port 7
Air gauge 9 is provided with place, air pressure detection hole 10.
Spring 8 has two, and two springs 8 are in extended state.
Rubber seal 13 is provided between the tank mouth of cover plate 12 and tank body 1.
Operation principle of the present utility model is as follows：
The sealing of outermost weight can be realized between outer cover 5 and ring flange 2 by rubber gasket 3, it is inside by valve 6
