Abstract
The utility model discloses a kind of sealing structure of cylinder valve, include rubber seal, valve body, valve element, annular slot is provided with the valve core sealed cover, it is the clamping face of splayed opening obliquely that the annular slot, which has a cross sectional shape, the rubber seal is set on the clamping face in annular slot, seal can be effectively blocked, prevents seal from coming off, and reaches good sealing.
Description
Technical field
The utility model belongs to low pressure natural gas supply technology field, concretely relates to a kind of the close of natural gas bottle valve
Seal structure.
Background technology
The pressure of natural gas supply system often fluctuates, thus gas cylinder safely valve core will high-frequency folding, this
Sample just needs a kind of sealing structure to adapt to this condition of work.
The content of the invention
The purpose of this utility model is to provide a kind of sealing structure of natural gas bottle valve, its can good clamping seal,
Prevent seal from coming off, and reach preferable sealing effectiveness.
In order to solve the above technical problems, what the purpose of this utility model was realized in：
A kind of assembling structure of sealing ring, comprising rubber seal, valve body, valve element, it is provided with the valve core sealed cover
Annular slot, it is the clamping face of splayed opening obliquely that the annular slot, which has a cross sectional shape, the rubber seal
It is set on the clamping face in annular slot.
On the basis of such scheme and as the preferred scheme of such scheme：The valve core sealed cover is the conical surface, described
Annular slot is arranged on the bigger diameter end of the conical surface.
On the basis of such scheme and as the preferred scheme of such scheme：The conical surface bigger diameter end bottom is dismountable
Supporting part is installed, it is splay annular that the supporting part upper surface, which is provided with the cross sectional shape relative with the annular slot,
Groove.
On the basis of such scheme and as the preferred scheme of such scheme：The annular groove and annular slot are formed
One semi-enclosed cavity, the rubber seal are mostly in the cavity, and another part exposes from unclosed.
On the basis of such scheme and as the preferred scheme of such scheme：The rubber seal is O-ring.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：The splay clamping face of valve element is set,
And supporting part splayed annular groove on the other side coordinates, and can effectively block seal, prevent seal from coming off, and reach
To good sealing.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is sealing structure close-up schematic view.
1st, valve element 2, supporting part 3, valve body 4, seal.
Embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with the accompanying drawing in embodiment, to reality
The technical scheme applied in example is clearly and completely described, it is clear that described embodiment is only that the application part is implemented
Example, rather than whole embodiments.Based on the embodiment provided, those of ordinary skill in the art are not before creative work is made
The every other embodiment obtained is put, belongs to the scope of the application protection.
In the description of the present application, it is to be understood that the orientation or position relationship of the instruction such as term " on ", " under " are base
In orientation shown in the drawings or position relationship, it is for only for ease of description the application and simplifies description, rather than indicate or imply
Signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this
The limitation of application.
In the description of the present application, term " first ", " second " etc. be only used for describe purpose, and it is not intended that instruction or
Imply relative importance or the implicit quantity for indicating indicated technical characteristic.
It should be noted that term " electrolyte ", " gelatinizing agent " are the current material of this area and conventional use of material
Material, and above-mentioned technical characteristic is also inventive point not of the invention, therefore, is not made for the composition of " electrolyte ", " gelatinizing agent "
Repeat.
A kind of assembling structure of sealing ring, comprising rubber seal, valve body, valve element, it is provided with the valve core sealed cover
Annular slot, it is the clamping face of splayed opening obliquely that the annular slot, which has a cross sectional shape, the rubber seal
It is set on the clamping face in annular slot.
Valve core sealed cover is the conical surface, and the annular slot is arranged on the bigger diameter end of the conical surface.
The conical surface bigger diameter end bottom is removably provided with supporting part, and the supporting part can be connected through a screw thread, clamping
It is fixed on etc. mode on valve element, it is dismountable that the seal for being conveniently replaceable damage is set.
It is splay annular groove that the supporting part upper surface, which is provided with the cross sectional shape relative with the clamping face, this
Rubber seal is preferably fixed on valve element by the setting can of sample.
Preferably, the annular groove and annular slot enclose a semi-enclosed cavity, and the rubber seal is big
It is partially in the cavity, another part exposes from unclosed, thus preferably prevents rubber seal from installation position
Abjection.
Preferably, the rubber seal is O-ring, and O-ring good sealing effect is cheap, convenient to obtain.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection model of the present utility model according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
Within the scope of.
