Description
Technical field
It the utility model is related to the mechanical interface technical field that pipeline is not got angry, more particularly to a kind of gas pipeline is close
Seal apparatus.
Background technology
Now, steel pipe or nodular cast iron pipe are generally used in gas industry as fuel gas transportation pipeline, although steel pipe, cast iron
The high mechanical strengths such as the pressure-resistant and impact resistance of pipe, but still there is due to material is bad or construction wrong caused by
Gas leakage hidden danger.The gas leakage of gas pipeline caused by which kind of reason is all the major accident for not allowing to occur,
Therefore leakage once occurs, it is necessary to is fast and effectively rushed to repair.But at present, existing gas pipeline rush to repair accessory use into
This height, poor practicability, therefore, for current Industry, that is most short of makes ripe effective damage repair technology and handy
Repairing instrument and repairing part.
Utility model content
The purpose of this utility model is for overcome the deficiencies in the prior art, there is provided a kind of gas pipeline sealing device.
The utility model is to be achieved through the following technical solutions：
The utility model provides a kind of gas pipeline sealing device, and the gas pipeline sealing device includes：For combustion gas
On pipeline to pore closure plugging seal, the plugging seal include nut, under the nut square washer, be located at
The packing ring lower section and the sealing ring being tapered down and the screw rod coordinated with the nut；The screw rod lower end is connected with post
Plug, is provided with the card article of circle band elasticity on the plunger, the both ends of every card article be connected to the plunger upper end and
The lower end of the sealing ring.
Preferably, the material of the sealing ring and the plunger is the rubber of resistance to combustion gas.
Preferably, the lower end of the plunger is circular arc.
Preferably, the radius of the plunger is more than the internal diameter of the sealing ring.
Preferably, the card article is made up of resistance to combustion gas material.
The beneficial effects of the utility model are：Pore can be blocked by the plugging seal of setting and reach good tight
The purpose of property, Fast Installation, and meanwhile it is simple in construction, it is easy to operation.
Brief description of the drawings
Fig. 1 is the structural representation for the gas pipeline sealing device that the utility model embodiment provides.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Referring to Fig. 1, Fig. 1 is the structural representation for the gas pipeline sealing device that the utility model embodiment provides.
The utility model embodiment provides a kind of gas pipeline sealing device, and the gas pipeline sealing device includes：With
In, to the plugging seal 1 of pore closure, the plugging seal 1 includes nut 2, under the nut 2 on gas pipeline
The packing ring 3 of side, positioned at the lower section of the packing ring 3 and the sealing ring 4 that is tapered down and and the screw rod 5 that coordinates of the nut 2；Institute
State the lower end of screw rod 5 and be connected with plunger 6, the card article 7 of circle band elasticity, the both ends difference of every card article 7 are provided with the plunger 6
It is connected to the upper end of the plunger 6 and the lower end of the sealing ring 4.
In the above-described embodiments, pore can be blocked to the mesh for reaching good tightness by the plugging seal 1 of setting
, Fast Installation, at the same it is simple in construction, it is easy to operation.
In order to facilitate the gas pipeline sealing device for understanding that the utility model embodiment provides, implement with reference to specific
It is described in detail example.
With continued reference to Fig. 1, the gas pipeline sealing device includes a plugging being used on gas pipeline to pore closure
Seal 1, the plugging seal 1 include nut 2, the packing ring 3 positioned at the lower section of the nut 2, positioned at the lower section of packing ring 3 simultaneously
The sealing ring 4 being tapered down and the screw rod 5 coordinated with the nut 2.The lower end of screw rod 5 is connected with plunger 6, the post
It is provided with the card article 7 of circle band elasticity on plug 6, the both ends of every card article 7 are connected to the upper end of the plunger 6 and described close
The lower end of seal 4.The material of the sealing ring 4 and the plunger 6 is the rubber of resistance to combustion gas, and the card article 7 is also resistance to combustion gas material
It is made.The lower end of the plunger 6 is circular arc, and the radius of the plunger 6 is more than the internal diameter of the sealing ring 4.
When specifically used, the screw rod 5 is screwed into the pore counterclockwise, then positive hour hands rotate the nut 2, institute
State card article 7 slowly fluffy and to support on the gas pipeline inwall, filled in until by the sealing ring 4 in the pore, institute
State plunger 6 and be closely attached to the lower end of sealing ring 4.
By foregoing description as can be seen that the gas pipeline sealing device that the present embodiment provides is sealed by the plugging of setting
Part 1, which can block pore, reach the purpose of good tightness, Fast Installation, while simple in construction, easy to operation.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
