Abstract

The utility model discloses a device for quickly covering leak in a pipeline, which is characterized in that the utility model is composed of press covers, sealing rings, an intermediate body, a sealing pad and a fastening piece, wherein, the press covers, the sealing rings and the intermediate body all adopt split type, the intermediate body is appressed with the crack point of the pipe to clamp, the intermediate body is connected with the pipe by a bolt, and then, a nut and two sealing rings are screwed on the bolt, the press covers are respectively installed at both ends of the intermediate body, causing the intermediate body sealing rings and the press covers to attach mutually, both end press covers are connected with each other by the bolt, and then, the nut is screwed on the bolt. Both end structures of the intermediate body are the same. The product has simple product structure, quick installation and easy seal. When the crack point of the pipe has a fracture, the utility model can be used as a pipeline telescopic joint.

Description

Device for quickly covering leak in pipe

The utility model relates to a kind of pipeline instantaneous leaking-stopping device, is used for town and country water supply and sewerage pipeline explosion seepage and repairs the field.

At present, China's town and country water supply and sewerage pipeline is because the variation of nature temperature, explosion easily takes place in reasons such as pipe network is aging, cause seepage, place under repair is to block the water pipe that breaks generally speaking, adorns the preceding paragraph again and newly manages, and can cause water supply system to interrupt like this, and the road breaking area is very big, brings difficulty for resident, office, factories and miness; The sewage of drainage system also enters water supply pipe easily, the harm health of human body; Exhausting, industrial water that this method for maintaining not only can not stop for every minute and second bring difficulty, and maintenance procedures is very complicated, heavy.

The purpose of this utility model provides a kind of pipeline instantaneous leaking-stopping device of realizing instantaneous leaking-stopping under the situation that does not stop plumbing, and it can not only be avoided, and the energy runs off, environmental pollution, and facilities are as good as new, construction amount is few to guarantee plumbing.

The purpose of this utility model is achieved in that it is made up of gland 1, seal ring 2, intermediate 3, bolt, nut and sealing gasket 8: gland 1, seal ring 2 and intermediate 3 are semicircle opposite; Add seal ring 2 on the intermediate 3; Gland 1, seal ring 2 are triangular in shape; Install sealed at both endsly, intermediate is sealed into the O type; Intermediate 3 involutory clampings add sealing gasket 8 again at the pipeline burst place, cover sealed at both ends circle 2 and gland 1 then, connect two glands and intermediate 3 is integral with connecting bolt, the nut diagonal angle are screwed onto till the no medium seepage equably again.

Owing to adopt such scheme, the utlity model has following excellent characteristics:

1. the excavated pavement area is less, traditional repairing leakage need be transferred pipe, the leakage work of repairing of φ 100mm to φ 200mm is anti-will excavate 0.6m * 1.5m square metre of area, and after using " pipeline instantaneous leaking-stopping device ", area narrows down to 0.5m * 1.0m square metre, repaiies Lou average redeck expense (0.6 * 1.5-0.5 * the 1.0) * 118.00=47.20 unit that saves for every.

2. alleviated labor intensity, tradition is repaiied and is leakage wanted pipe cutting, make joint by putting new pipe, and " pipeline instantaneous leaking-stopping device " has save above three process, and has been merged into the accessory clamping on water pipe, tightens with bolt to get final product.

3. shortened and repaiied the leakage time, the three process that tradition is repaiied leakage generally need add shoveling etc. with 4 hours, repair a leakage and use time half a day, and repaiied a leakage needs 2～3 hours after using " pipeline instantaneous leaking-stopping device ", can resume traffic in advance, water flowing in advance recovers the service provision ability in advance.

4. can avoiding cuts off the water supply repaiies leakage, to less the repairing leakage of generally leaking, uses " pipeline instantaneous leaking-stopping device " can avoid traditional and cuts off the water supply the pipe cutting mode and carry out under the situation of not cutting off the water supply, and helps safety water supply, guarantees service.

5. help producing and help economy, calculate by industrial output value, general each ton water can be created 100 yuan industrial output value, use " pipeline instantaneous leaking-stopping device " under the situation of not cutting off the water supply, the water pipe of φ 150mm is repaiied leakage and was calculated by 4 hours, 4 hours 270 tons of water meters of supply can be done sth. in advance, 27,000 yuan of industrial output values can be created.

Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.

Fig. 1 is the utility model example structure schematic representation.

Fig. 2 is the utility model example structure plan view.

Fig. 3 is the utility model example structure longitudinal section.

Fig. 4 is the cross-sectional figure of the utility model example structure.

Fig. 5 is the utility model embodiment intermediate 3 sealing sectional drawings.

Fig. 6 is that the utility model embodiment user mode is with reference to half sectional view.

Among the figure: 1, gland, 2, seal ring, 3, intermediate, 4～6, bolt, 5,7, nut, 8, sealing gasket.

In Fig. 1-5, this device comprises an intermediate 3, and intermediate 3 is two semicircle opposites, to being combined on the outer diameter tube of breaking, put sealing gasket 8 again, two ends put the seal ring 2 of opposite, compress the gland 1 of opposite, and gland 1, seal ring 2 are triangular in shape, easily sealing, adopt bolt 4 to be connected two glands 1 with 6, become one, till

nut

5,7 diagonal angles are screwed onto no medium equably and ooze with intermediate 3.Whole device is sealed at both ends; Intermediate 3 sealings are the O type, and the medium that explosion vent flows out can only be flowed in this device, guaranteed the sealing of pipeline, thereby it are unimpeded to have reached fed sheet of a media, purpose of safety.The spheroidal graphite cast iron manufacturing of this product also can be made of forging cast iron, steel and corrosion resistant metallic material.

During use, explosion place that earlier 3 pairs in intermediate is clipped in pipe adds sealing gasket 8 again, connect with bolt 5, and with nut be screwed to two intermediate cracks airtight till.Again two seal rings 2, gland 1 are installed in the two ends of intermediate 3 respectively, and intermediate 3 seal rings 2 and gland 1 are fitted mutually, with bolt 4 the two ends gland is connected then, the nut 5 of screwing on, nutting answers the diagonal angle to twist equably, makes two glands keep balance, is screwed onto medium and stops till the seepage.Because two-end structure is identical, so suitable reverse needn't consider to install the time.
