Abstract
The utility model provides an in the perforation, through the securing nut messenger that two -sided plugging device, packing element suit are on the conical screw, and suit clamp plate behind the packing element is stretched out in the anterior internal cone hole and the supporting contact of the cone of conical screw front end of packing element, the rear end of conical screw, and there is the external screw thread rear end of conical screw, and the internal thread of nut closes with the external screw thread of conical screw rear end soon, and the clamp plate is pushed down to the nut, and the clamp plate is pressed on the outer terminal surface of packing element, on the outer circular cone wall contract of the packing element income pipeline the packing element is out of shape and is the both ends evagination, and the appearance of its evagination part is greater than the perforation size of pipeline, makes the outer teat in packing element both ends hug closely the outer both sides of wind of pipeline, and during rotatory nut, the cone of conical screw front end struts the left end evagination position of packing element and swells, makes it hug closely and forms sealed face at pipeline inboard, and simultaneously, the clamp plate is to packing element right -hand member evagination position generate pressure, hugs closely after making its deformation swell to form sealed face in the outside of pipeline, forms two -sided sealing up.
Description
Technical field
The utility model is the equipment carrying out pressure sealing after having the perforation on pressure line, is a kind of two-sided leakage-baffling device.
Background technique
Liquid conveying, will through transfer line in storage process, transfer line is after using for a long time, and there will be the problem of damaged perforation, particularly carry, store when having certain corrosive liquids, the problem of damaged perforation can often occur.Processing method after current generation pipeline breakage perforation has a variety of, and have steel band leak stopping, clamp leak stopping, timber wedge leak stopping etc., these blocking methods are one side shutoff, and plugging effect is unreliable, and leakage phenomenon again easily occurs.And the device assembly used in these blocking methods is more, and during operation, operation is numerous and diverse, wastes time and energy.Above-mentioned blocking method all needs manually-operable, and face and shirtfront just to thorn spray direction, easily damage accident, there is potential safety hazard.
Summary of the invention
The purpose of this utility model is a kind of two-sided leakage-baffling device of design, overcomes and above-mentionedly deposits large problem, can easy, perforation fast on blocking pipe, improves plugging effect, extends leak stopping effective date.
The purpose of this utility model is achieved in that perforation place for being arranged on pipeline, comprise pipeline, packing element, pressing plate, nut, conical screw, 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, pressing plate is set with after packing element is stretched out in the rear end of conical screw, there is outside thread the rear end of conical screw, the internal thread of nut and the outside thread of conical screw rear end screw, nut pushes down pressing plate, pressing plate is pressed on the exterior edge face of packing element, the outer cone wall contract of packing element enters in the perforation on pipeline, described packing element is made to be out of shape in two ends evagination by fastening nut, the profile of its projecting segments is greater than the hole dimension of pipeline, packing element two ends outwardly projecting portion is made to be close to the outer both sides of wind of pipeline.
Pipeline clamps support, and the right-hand member of support is sleeved on the outer end of conical screw.
The beneficial effects of the utility model are: outwards walk at threaded function inferior pyramidal screw rod during rotary nut, when conical screw is outwards walked and packing element produce relative movement, the left end evagination position of packing element struts and swells by the cone of conical screw front end, the inner side making it be close to pipeline forms sealing surface, simultaneously, pressing plate produces pressure to packing element right-hand member evagination position, the outside being close to pipeline after making it be out of shape to swell forms sealing surface, thus reach the object of dual face seals, perforation pipeline is made again to be in air-tight state, the utility model can be easy, perforation fast on blocking pipe, improve plugging effect, extend leak stopping effective date.Do not need face and shirtfront during operation just to thorn spray direction, can not damage accident, there is not potential safety hazard, therefore, the utility model has significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is erection drawing of the present utility model.
Embodiment
Below in conjunction with Fig. 1, embodiment of the present utility model is described:
As shown in the figure, embodiment of the present utility model is for being arranged on perforation place of pipeline, comprise pipeline 1, packing element 2, pressing plate 3, nut 4, conical screw 5, support 6, packing element 2 is sleeved on conical screw 5, the inner circle taper hole of packing element 2 front portion contacts with the cone of conical screw 5 front end is supporting, packing element 2 rear suit pressing plate 3 is stretched out in the rear end of conical screw 5, there is outside thread the rear end of conical screw 5, the internal thread of nut 4 and the outside thread of conical screw 5 rear end screw, nut 4 pushes down pressing plate 3, pressing plate 3 is pressed on the exterior edge face of packing element 2, the outer cone wall contract of packing element 2 enters in the perforation on pipeline 1, described packing element 2 is made to be out of shape in two ends evagination by fastening nut 4, the profile of its projecting segments is greater than the hole dimension of pipeline 1, packing element 2 two ends outwardly projecting portion is made to be close to the outer both sides of wind of pipeline 1.Pipeline 1 clamps support 6, the right-hand member of support 6 is sleeved on the outer end of conical screw 5, makes it easy to operation rotary nut or packing element 2 is out of shape.Fluted in the profile of packing element 2, during distortion, the easy projection in two ends realizes dual face seals.
