Abstract

The invention relates to a plugging device with pressure. A rubber barrel is arranged on a conical screw, an inner conical hole of the front portion of the rubber barrel contacts with a cone of the front end of the conical screw in a matched manner, and the rear end of the conical screw extends out of the rubber barrel and then a washer is sleeved on the rear end. An external thread is arranged at the rear end of the conical screw, and an internal thread of a screw cap is screwed with the external thread of the rear end of the conical screw. The screw cap presses the washer, the washer is pressed on an outer end face of the rubber barrel, an outer conical wall of the rubber barrel is implanted in a through hole on a through hole pipeline, friction is caused by a contact surface of the outer conical wall of the rubber barrel and the through hole pipeline, and an inner wall of the rubber barrel covers the conical screw, so that the conical screw can not rotate during the rotation of the screw cap, and under the act of the threads, the conical screw travels outwardly during the rotation of the screw cap and is in relative motion with the rubber barrel. The rubber barrel is stretched and expanded by the cone of the front end of the conical screw so that the hole is completely stuffed, and the through hole pipeline is back to be airtight. Due to the fact that parts left on the pipeline are small, the device can be matched with a gathering transportation pipe network non-flame repairing device with pressure for composite plugging, and plugging effect is improved.

Description

A kind of tape-pressure leakage clogging device
Technical field
The present invention carries out the equipment that pressure sealing is used after the perforation had on pressure line, is a kind of tape-pressure leakage clogging device.
Background technique
Liquid will pass through transfer line in conveying, storage process, and transfer line, after long use, there will be the problem of damaged perforation, particularly carries, stores while having certain corrosive liquids, and the problem meeting of damaged perforation often occurs.The processing method occurred at present after the pipeline breakage is bored a hole is generally to stop production, and removes liquid, to security department, proposes to get angry application, after reaching the condition of getting angry by inspection, just can carry out soldering, these programs of process several hours at least, tens days at most, have a strong impact on normal production.Because can not process in time, the liquid in pipeline is uncontrollable and run off, and causes heavy economic losses, and befouling environment, needs to drop into pollution abatement costs.Chinese patent application 201220489782.6 " oil transport pipeline perforation plugging device ", can with pressurely install, leak on the temporary transient blocking pipeline of energy, but, because its boundary dimension is large, can not coordinate the collection transmission pipe network repairing device xxxxx with pressure that do not get angry to carry out compound leak stopping, therefore, the leak stopping effective date of Chinese patent application 201220489782.6 " oil transport pipeline perforation plugging device " is short, can not after dismounting with pressure, carry out again leak stopping, and its use inconvenience, can not the fast blocking perforation.
Summary of the invention
The objective of the invention is to design a kind of tape-pressure leakage clogging device, it is not stopped production, can be easy, the perforation on blocking pipe fast, and can coordinate the collection transmission pipe network repairing device with pressure of not getting angry to carry out compound leak stopping, and improve plugging effect, extend the leak stopping effective date.
The object of the present invention is achieved like this: comprise packing element, packing ring, screw cap, conical screw, on the perforation pipeline, perforation is arranged, packing element is sleeved on conical screw, the inner circle taper hole of packing element front portion contacts with the cone of conical screw front end is supporting, the rear end of conical screw is set with packing ring after stretching out packing element, there is outside thread the rear end of conical screw, the outside thread of the internal thread of screw cap and conical screw rear end screws, screw cap is pushed down packing ring, packing ring is pressed on the exterior edge face of packing element, in the perforation that the outer cone wall contract of packing element enters to bore a hole on pipeline.
The invention has the beneficial effects as follows: after in the perforation that the outer cone wall contract of packing element enters to bore a hole on pipeline, with the surface of contact of perforation pipeline, produce frictional force, the packing element inwall encases conical screw, its conical screw when the rotary screw cap can not be rotated, during the rotary screw cap, at threaded function inferior pyramidal screw rod, outwards walk, when conical screw is outwards walked and packing element produce relative movement, the cone of conical screw front end struts packing element to swell, make it fill the perforation hole on the perforation pipeline fully, make to bore a hole pipeline again in air-tight state, realize pressure sealing, after pressure sealing completes, because the parts of staying on pipeline are little, can coordinate again the collection transmission pipe network repairing device with pressure of not getting angry to carry out compound leak stopping, can improve plugging effect, extend the leak stopping effective date, there is significant economic benefit.
The accompanying drawing explanation
Accompanying drawing is erection drawing of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described:
As shown in the figure, embodiments of the invention comprise perforation pipeline 1, packing element 2, packing ring 3, screw cap 4, conical screw 5, on perforation pipeline 1, perforation is arranged, packing element 2 is sleeved on conical screw 5, the supporting contact of cone of the inner circle taper hole of packing element 2 front portions and conical screw 5 front ends, the rear suit packing ring 3 of packing element 2 is stretched out in the rear end of conical screw 5, suit packing ring 3 is for enlarge active surface, there is outside thread the rear end of conical screw 5, the outside thread of the internal thread of screw cap 4 and conical screw 5 rear ends screws, screw cap 4 is pushed down packing ring 3, packing ring 3 is pressed on the exterior edge face of packing element 2, in the perforation that the outer cone wall contract of packing element 2 enters to bore a hole on pipeline 1.
The outside thread of conical screw 5 rear ends is straight button screw thread, and the front end of conical screw 5 refers to middle left-hand component shown in accompanying drawing, and the rear end of conical screw 5 refers to middle right-hand component shown in accompanying drawing.
The present invention has plurality of specifications, according to the size and shape of perforation on perforation pipeline 1, selects different size.
