Abstract
The utility model discloses a kind of gas pipelines to block capsule, metal mouth including oval capsule body and two tubuloses, oval capsule body has intracapsular chamber and the Nang Kou positioned at intracapsular chamber both ends, each tubular metal mouth has tube cavity, the top of tubular metal mouth is thread segment, lower part is linkage section, the linkage section difference bonding by Vulcanization of two tubular metal mouth lower parts is in the capsule mouth at intracapsular chamber both ends, the tube cavity of each tubular metal mouth is connected with the intracapsular chamber of the oval capsule body, and dead ring is arranged with outside the Nang Kou at intracapsular chamber both ends；The ellipse capsule body is formed by the rubber layer bonding by Vulcanization of intermediate reticulated bone rack-layer and disposed within, outer two sides.The convenient working hole opened up on maintenance pipeline of the utility model is put into or takes out, the combination of metal mouth and Nang Kou are also stronger, reliable, when gas pipeline closure capsule being pulled out through working hole after maintenance activity, metal mouth will not pull off from the Nang Kou of capsule body.
Description
Technical field
The utility model relates to a kind of gas pipelines of blocking pipe in gas pipeline maintenance to block capsule.
Background technique
When the fuel gas transportation pipeline being damaged is repaired or repaired, first the pipeline capsule of damage is blocked
Come, wait be damaged pipeline maintenance after capsule is taken out again.It is frequently used for the capsule of blocking pipe in gas pipeline maintenance, is had
The spherical capsule body of rubber material, the Nang Kou of spherical capsule body are equipped with the metal mouth of tubulose, and the upper section of tubular metal mouth has outside connection
Screw thread, radial circular ring shape scapulet is connected at lower section nozzle, and the tube cavity of metal mouth is communicated with the inner cavity of spherical capsule body.In use,
Working hole is outputed on duct wall, gas pipeline is blocked capsule and is placed in pipeline through working hole, from capsule mouth metal mouth to spherical shape
The inner cavity of capsule body is passed through compressed air, and spherical capsule expands in pipeline, and excircle is tight against the circumference in inner wall of the pipe, pipeline
Closure is got up, and after maintenance activity, the compressed air of spherical capsule body inner cavity is discharged, and holds the metal mouth at Nang Kou closure glue
Capsule is pulled out from pipeline back warp working hole.In the prior art, gas pipeline blocks the metal mouth and capsule body combined process pressure of capsule
It is low, density is small, shape is lack of standardization, slow to reveal.Nylon between the tubular metal mouth of this pipeline plugging rubber sac and spherical capsule body
The connection and irrational distribution of cord skeleton keep the bonding strength between tubular metal mouth and spherical capsule body not high, in order to improve
The thickness of intensity, spherical capsule body is larger, causes the rigidity of spherical capsule body larger, and pipeline plugging rubber sac is placed on pipeline from working hole
In and while being pulled out through working hole it is all highly difficult, especially pipeline plugging rubber sac is pulled out through working hole after maintenance activity
When, it is easy to metal mouth is pulled off from spherical capsule.
Utility model content
It is put into or is taken out by working hole the technical problem to be solved by the present invention is to provide convenience when a kind of maintenance and is golden
Belong to mouth and Nang Kou is tightly combined, firm gas pipeline blocks capsule.
In order to solve the above technical problems, the gas pipeline of the utility model blocks capsule, including oval capsule body and two
The metal mouth of tubulose, oval capsule body have intracapsular chamber and the Nang Kou positioned at intracapsular chamber both ends, and each tubular metal mouth has pipe
Inner cavity, the top of tubular metal mouth is thread segment, lower part is linkage section, and the linkage section of two tubular metal mouth lower parts vulcanizes respectively
It is bonded in the capsule mouth at intracapsular chamber both ends, the tube cavity of each tubular metal mouth is connected with the intracapsular chamber of the oval capsule body
It is logical, dead ring is arranged with outside the Nang Kou at intracapsular chamber both ends；The ellipse capsule body by intermediate reticulated bone rack-layer and it is disposed within,
The rubber layer bonding by Vulcanization of outer two sides forms.
The reticulated bone rack-layer is the aramid fiber capsule to match with the oval capsule figure shape of an aramid line braiding
Bag.
The metal mouth is brass mouth.
Gas pipeline using the above structure blocks capsule, since oval capsule body by intermediate reticulated bone rack-layer and is placed in
The rubber layer bonding by Vulcanization of its inside and outside two sides forms so that capsule also have in the case where need not increase thickness it is preferable strong
Degree, the convenient working hole opened up on maintenance pipeline is put into or takes out, while but also the combination of metal mouth and Nang Kou are more firm
Solid, it is reliable, when pipeline plugging rubber sac being pulled out through working hole after maintenance activity, metal mouth will not be from the Nang Kou of capsule body
It pulls off.In addition, since the capsule body both ends in the utility model are equipped with metal mouth, when use, can be by jointing two sheets
Utility model is applied in combination, and realizes more preferable closure and sealing to pipeline to be repaired.Reticulated bone rack-layer in the utility model is adopted
It, can be into one after technical characteristic with the aramid fiber pouch to match with the oval capsule figure shape by an aramid line braiding
Step improve capsule body crushing resistance, can blocking high-pressure gas pipeline, pressure-resistant 0.8MPa No leakage.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the schematic cross-sectional view that a kind of gas pipeline of the utility model blocks capsule.
Fig. 2 is that one end eliminates Fig. 1 after metal mouth and dead ring.
Specific embodiment
Referring to Fig. 1, Fig. 2, the gas pipeline of the utility model blocks capsule, including oval capsule body 10 and two tubuloses
Metal mouth 20, oval capsule body 10 have intracapsular chamber 11 and the capsule mouth 12 positioned at intracapsular chamber both ends, and each tubular metal mouth 20 has
There is tube cavity 21, the top of tubular metal mouth 20 is thread segment 22, lower part is linkage section 23, two 20 lower parts of tubular metal mouth
Linkage section 23 distinguish bonding by Vulcanization in the capsule mouth 12 at intracapsular chamber both ends, the tube cavity 21 of each tubular metal mouth 20 with it is described ellipse
The intracapsular chamber 11 of rounded sac body 10 is connected, and dead ring 13 is arranged with outside the capsule mouth 12 at intracapsular chamber both ends；The ellipse capsule body
10 are formed by intermediate reticulated bone rack-layer 14 and the rubber layer 15 of disposed within, outer two sides, 16 bonding by Vulcanization.The reticulated bone
Rack-layer 14 is the aramid fiber pouch to match with oval 10 shape of capsule body of an aramid line braiding.The metal mouth 20
For brass mouth.
