Abstract

The utility model discloses a rubber choke plug used for a gas pipeline. The rubber choke plug used for the gas pipeline comprises a nut and a taper bolt, wherein the nut and the taper bolt are matched with each other. A rubber part is arranged on the taper bolt in a sleeved mode. The rubber part comprises a straight body part and an oblique body part. A pressing plate is further arranged between the oblique body part and the nut. The pressing plate is arranged on the taper bolt in a sleeved mode. The rubber choke plug used for the gas pipeline is simple in structure, convenient to operate, free from naked light and high temperature, and safe in construction and can not damage the material structure of a metal pipeline. Due to adoption of nodular cast iron materials, the nut and the taper bolt are strong in corrosion resistance and compression strength. Due to adoption of nitrile rubber, the rubber part is good in gas resistance and ageing resistance. The rubber choke plug used for the gas pipeline can be used for chocking a nodular cast iron pipe, a steel pipe and a polythene (PE) pipe and has a wide application range.

Description

Gas pipeline with rubber silently
Technical field
The utility model relates to a kind of gas pipeline with rubber silently.
Background technique
When carrying out gas shutoff repairing pipeline with the combustion gas choke ball, need to hole to allow choke ball fill in pipeline on tube wall, construction end meeting leaves aperture on tube wall.In prior art, the hole on tube wall is by the silently shutoff of thread metal, but operation is comparatively complicated, and present gas pipeline generally adopts steel pipe, PE plastic tube, because tube wall is thinner, can't tapping on tube wall, bring difficulty to the shutoff operation during pipe first-aid.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of gas pipeline with rubber silently, to realize quick, the efficient shutoff of gas pipeline.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of gas pipeline with rubber silently comprises the nut and the taper bolt that cooperatively interact, is arranged with rubber parts on described taper bolt.
Preferably, described rubber parts comprises straight body section and oblique body section.
Preferably, also be provided with pressing plate between described oblique body section and nut, described pressing plate is set on described taper bolt.
By technique scheme, the gas pipeline that the utility model provides with rubber silently has following advantage compared to existing technology:
1. simple in structure, easy to operate, only need one spanner tightening nut, quick construction;
2. there is no naked light, high temperature, construction safety can not destroy the material structure of metallic conduit;
3. nut and taper bolt adopt ductile cast iron material, and be corrosion-resistant, compressive strength is high; Rubber parts adopts nitrile butadiene rubber, and anti-combustion gas, ageing resistance are good;
4. ductile iron pipe, steel pipe, PE pipe etc. all can use the utility model to carry out shutoff, and are applied widely.
Description of drawings
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, during the below will describe embodiment, the accompanying drawing of required use is done to introduce simply.
Fig. 1 is the disclosed gas pipeline of the utility model embodiment with rubber structural representation silently;
Fig. 2 is the schematic diagram that rubber shown in Figure 1 is in reset condition when silently being used for the gas pipeline shutoff;
Fig. 3 is the schematic diagram that rubber shown in Figure 1 is in swelling state when silently being used for the gas pipeline shutoff.
Numeral in figure:
11. the nut 12. oblique body of pressing plate 13. sections
14. straight body section 15. taper bolt 21. gas pipelines
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
According to Fig. 1, the gas pipeline that the utility model provides with rubber silently, comprise the nut 11 and the taper bolt 15 that cooperatively interact, be arranged with rubber parts on taper bolt 15, rubber parts comprises straight body section 14 and oblique body section 13, tiltedly also is provided with the pressing plate 12 that is set on taper bolt 15 between body section 13 and nut 11.
When using the utility model to carry out the gas pipeline shutoff, at first rubber is silently filled in the pipe tap of gas pipeline 21, as shown in Figure 2, made the hole wall of the oblique body section 13 respective tube cinclides of rubber parts; Then nut 11 screws up with a wrench, 11 pairs of pressing plates 12 of nut and rubber parts are exerted pressure, thereby the taper bolt 15 in rubber parts is upwards drawn, taper bolt 15 radially struts rubber parts, straight body section 14 becomes, tiltedly body section 13 gradually radially outward expand and with pipe tap stop up, sealing, thereby stop gas leakage when gas pipeline 21 repairing, as shown in Figure 3.
Multiple modification to above-described embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.

Claims (3)

1. a gas pipeline with rubber silently, is characterized in that, comprises the nut and the taper bolt that cooperatively interact, is arranged with rubber parts on described taper bolt.
2. gas pipeline according to claim 1 with rubber silently, is characterized in that, described rubber parts comprises straight body section and oblique body section.
3. gas pipeline according to claim 2 with rubber silently, is characterized in that, also is provided with pressing plate between described oblique body section and nut, and described pressing plate is set on described taper bolt.
