Abstract

The utility model discloses a pipeline plugging device provided with a front tight propping flange, a polyurethane sealing ring, a trapezoidal cylinder, a slip and a rear tight propping flange which are connected in sequence through periphery penetrated bolts, wherein the slip is a trapezoidal cylinder formed by a plurality of separated slip pieces arranged in a surrounding manner, and a lock-on spring ring is arranged at the circumference of the slip; the front ends of the bolts are fixed at the periphery of the front tight propping flange, and fixing nuts are arranged at the rear ends of the bolts; a communicating hollow tube is arranged in the middles of the bolts; a tight propping spring is arranged on the bolt between the trapezoidal cylinder and the slip; a rubber ring is further arranged at the circumference of the slip; and a hydraulic cylinder is arranged on the bolt between the rear tight propping flange and the nut. The pipeline plugging device provided by the utility model is suitable for pipeline plugging, has a perfect structure, is convenient and flexible to use, has an excellent plugging effect, and is safe and reliable.

Description

The pipe plugging device
Technical field
The utility model relates to a kind of pipeline rehabilitation device technique field, specifically is the device that carries out shutoff for to pipe leakage place or pipe head, is applicable on the ground, the underground and shutoff of various pipelines under water.
Background technique
The shutoff of pipe leakage place or pipe head is that the shutoff of very important engineering, particularly submarine pipeline during pipeline is installed and keeped in repair, submarine pipeline and under ground piping is particularly difficult, is a great problem in the pipeline installation and maintenance.At present, the instrument that carries out pipe plugging is less, and is particularly special-purpose, be used under water with effective portable tool of pressure conduit shutoff or device seldom.Therefore, need to propose a kind of device easily and effectively for the pipe plugging maintenance.
The model utility content
The purpose of this utility model is in order to solve the problems of the technologies described above, to propose a kind of pipe plugging device, this blocking device, and structure is perfect, and is easy to use, good especially to the plugging effect of pipeline.
The purpose of this utility model is achieved through the following technical solutions:
The pipe plugging device, it is characterized in that: hold out against before being provided with flange, polyamine fat seal ring, trapezoidal cylindrical body, slips, after hold out against flange, hold out against before described flange, polyamine fat seal ring, trapezoidal cylindrical body, slips, after hold out against flange and link together in regular turn by the bolt that periphery passes, before hold out against flange ear end face snap in the front-end face of polyamine fat seal ring, trapezoidal cylindrical ear end face snaps in the front-end face of slips, the slips sheet that described slips is separated by several piece surrounds a trapezoidal cylindrical body, and periphery is provided with the pinning spring ring; Hold out against the periphery of flange before the front end of described bolt is fixed on, the rear end of bolt is provided with set screw nut; In the centre of bolt, be provided with a hollow tube that is used for pressure testing, after passing respectively, this hollow tube holds out against flange, slips, trapezoidal cylindrical body, polyamine fat seal ring, before being fixed on, its front end holds out against the flange center place, before seeing through, its mouth of pipe holds out against flange.
The utility model further improves and the additional project of enforcement is:
Bolt between described trapezoidal cylindrical body and slips is provided with and holds out against spring.
Periphery at described slips also is provided with rubber ring.
Hold out against after described flange and nut bolt be provided with oil hydraulic cylinder.
Pipe plugging device of the present utility model has the plurality of advantages that structure is perfect, easy to use flexibly, plugging effect is good, safe and reliable.
