Abstract
Disclosed is a pipeline plugging rubber sac. An upper groove, a middle groove and a lower groove are circumferentially arranged on the lower section of a steel pipe of a metal mouth of a sac opening, nylon cord frameworks extending out of the sac opening are disposed at the sac opening of a spherical sac body and bound in the upper groove and the middle groove of the lower section of the steel pipe by nylon ropes, 6-30 reinforcing nylon ropes are evenly circumferentially distributed on the lower groove of the lower section of the steel pipe, the upper ends of the reinforcing nylon ropes are tied into the lower knob of the lower section of the steel pipe, the reinforcing nylon ropes are circumferentially evenly distributed in the spherical sac body, and the lower ends of the reinforcing nylon ropes are tied into a knob at the lower end of the spherical sac body. The nylon cord frameworks between the metal mouth and the spherical sac body are reasonably connected and distributed, the connection strength is higher, the thickness of the spherical sac body is small, the pipeline plugging rubber sac can be placed into a pipeline and pulled out of the pipeline from an operating hole easily, and since the connection strength between the metal mouth and the spherical sac body is higher, the metal mouth cannot be pulled off from the spherical sac body when the pipeline plugging rubber sac is pulled out via the operating hole after maintenance operation is completed.
Description
Technical field
The utility model relates to a kind of capsule that blocking pipe is used when oil transport pipeline keeps in repair, particularly a kind of blocking pipe enhancing skeleton of capsule.
Background technique
When the crude oil that is damaged and natural-gas transfer pipeline are rushed to repair or keeped in repair, get up the pipe ends shutoff that damages earlier, allow oil, with new pipeline the pipeline of damage is changed again from the bypass circulation.Capsule blocking pipe commonly used when oil transport pipeline keeps in repair, the pipe plugging capsule has the spherical capsule body of rubber material, rubber ball-shaped capsule body has the nylon cord skeleton, one end of spherical capsule body is connected with capsule mouth metal mouth, metal mouth has steel pipe, the epimere of steel pipe has to connect uses outside thread, the lower end mouth of pipe of steel pipe to be connected with circular radial annular scapulet, and the tube cavity of steel pipe communicates with the inner chamber of spherical capsule body.During use, on tube wall, leave working hole, the pipe plugging capsule is placed in the pipeline through working hole, feed pressurized air from capsule mouth metal mouth to the inner chamber of spherical capsule body, spherical capsule expands in pipeline, and excircle is tight against the circumference at inner-walls of duct, pipe plugging is got up, after maintenance operation finishes, discharge the pressurized air of spherical capsule body inner chamber, hold capsule mouth metal mouth the shutoff capsule is pulled out from pipeline back warp working hole.In the prior art, the metal mouth of pipe plugging capsule and capsule body combined process pressure is low, density is little, shape is lack of standardization, reveals slowly.Being connected and irrational distribution of nylon cord skeleton between the metal mouth of this pipe plugging capsule and the spherical capsule body, make the join strength between metal mouth and the spherical capsule body not high, in order to improve intensity, the thickness of spherical capsule body is bigger, cause the rigidity of spherical capsule body bigger, be placed on the pipe plugging capsule in the pipeline and very difficult when working hole is pulled out from working hole, particularly maintenance operation finish the back the pipe plugging capsule when working hole is pulled out, be easy to metal mouth is pulled off on one's body from spherical capsule.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes being connected and the rational pipe plugging capsule that distributes of nylon cord skeleton between a kind of metal mouth and the spherical capsule body.
The utility model is realized with the following method.
The pipe plugging capsule has the spherical capsule body of rubber material, spherical capsule body has the nylon cord skeleton, there is Nang Kou the upper end of spherical capsule body, the upper end of spherical capsule body is connected with capsule mouth metal mouth, metal mouth has steel pipe, the epimere of steel pipe has to connect uses outside thread, the lower end mouth of pipe of steel pipe is connected with circular radial annular scapulet, the tube cavity of steel pipe communicates with the inner chamber of spherical capsule body, the hypomere of steel pipe has along on the circumference, in, following three road grooves, there is the nylon cord skeleton that stretches out Nang Kou at the Nang Kou place of spherical capsule body, the nylon cord skeleton that stretches out Nang Kou with nylon rope be bundled in the steel pipe hypomere on, in the further groove, the low groove of steel pipe hypomere is uniformly distributed with six～32 Reinforced Nylon ropes along the circumference, the upper end of Reinforced Nylon rope ties up in the low groove of steel pipe hypomere, the Reinforced Nylon rope is uniformly distributed along the circumference in spherical capsule body, and the lower end of Reinforced Nylon rope binds into knot in the lower end of spherical capsule body.
The utility model has along on the circumference at the hypomere of steel pipe, in, following three road grooves, there is the nylon cord skeleton that stretches out Nang Kou at the Nang Kou place of spherical capsule body, the nylon cord skeleton that stretches out Nang Kou with nylon rope be bundled in the steel pipe hypomere on, in the further groove, the low groove of steel pipe hypomere is uniformly distributed with six～32 Reinforced Nylon ropes along the circumference, the upper end of Reinforced Nylon rope ties up in the low groove of steel pipe hypomere, the Reinforced Nylon rope is uniformly distributed along the circumference in spherical capsule body, the lower end of Reinforced Nylon rope binds into knot in the lower end of spherical capsule body, being connected and distributing rationally of nylon cord skeleton between metal mouth and the spherical capsule body, make the join strength between metal mouth and the spherical capsule body higher, the thickness of spherical capsule body can be less, the flexibility of spherical capsule body is bigger, the pipe plugging capsule is placed in the pipeline and when working hole is pulled out from working hole is easy to, because the join strength between metal mouth and the spherical capsule body is higher, maintenance operation finish the back the pipe plugging capsule when working hole is pulled out, can not pull off metal mouth on one's body from spherical capsule.Below in conjunction with accompanying drawing, the utility model is further described.
