Abstract

The utility model relates to a dredging device for pipelines, comprising an inflator, a one-way valve, a deflation valve, an air storing cylinder and an air discharging switch. Air generated by the inflator enters the air storing cylinder via the one-way valve and the deflation valve positioned on the front part of the one-way valve, the center of the front part of the air storing cylinder is provided with a conduit communicated with the outside, and the back end of the conduit is blocked by a rubber packing on the front end of the deflation valve when the air discharging switch is not started. Therefore, high air pressure can form in the air storing cylinder, and when high pressure draft ejects from the front end of the conduit, high pressure can be generated in the pipeline to be dredged to achieve the purpose of dredging.

Description

Pipe dredging device

The utility model relates to a kind of device that is used for dredging pipeline (as sewer), particularly relates to a kind of booster-type small pipeline dredging device.

Existing pipe-dredging apparatus mainly comprises large-scale specialty drain cleaner and small-sized home pipeline dredging device.The former structure complexity is unsuitable for the daily use of family; The most typical and the most universal home pipeline dredging device is a kind of by bowl-shape rubber bodies and long the manual utensil of forming, be commonly called as and carry son, its principle is to utilize the modification of rubber bodies, the air or the liquid of the pipeline enclosure that makes rubber bodies and be blocked are compressed, this compressive force is big extremely to a certain degree, obstruction will be pushed, thereby makes the pipeline conducting.But because the rubber enclosed space is less, thereby above-mentioned compressive force will be too big, and when this just caused line clogging serious, carrying son can not be with the pipeline conducting.

The purpose of this utility model is to provide a kind of structure the comparatively simple and strong small-sized household pipeline drainer of mediation ability, and this dredging device has function of increasing pressure.

For achieving the above object, pipeline drainer of the present utility model is by inflator, one way valve, gas receiver, formation such as vent valve and air escape cock, inflator is identical with existing small-sized hand-operated inflator, it is made up of the depression bar of cylindrical shell and band pad, the elementary compressed air of exportable elevated pressures, elementary compressed air enters gas receiver through one way valve, gas receiver comprises a conduit that is in communication with the outside, the inner of conduit is by the vent valve shutoff when inflator is inflated, vent valve comprises the cylindricality matrix, matrix front end (near conduit the inner) is provided with rubber pad, the rear end has a pore along y direction, this pore radially is communicated with the matrix space outerpace in the matrix front portion, vent valve is arranged in the position-limiting tube that links to each other with the one way valve gas outlet, when inflator is inflated and is penetrated gas by one way valve, gas pushes away before with vent valve, compress conduit the inner until rubber pad, the radial component of the pore on the vent valve matrix is connected with gas receiver at this moment, gas progresses into gas receiver through pore, because conduit is by shutoff, one way valve can only unidirectionally be supplied gas, so with the continuation of the process of inflating, the gas receiver internal pressure increases gradually.When pressure in the gas receiver is enough big, open vent valve, vent valve is a valve that is communicated with the position-limiting tube rear portion, opening this valve promptly is that the position-limiting tube rear portion is in communication with the outside, like this, because big pressure differential, vent valve quilt in valve open is very fast to pusher, thereby gases at high pressure are sprayed from conduit, and the pressure of gases at high pressure impels pipeline to be switched on.

The utility model make the compressive force that is produced be much higher than traditional son of carrying, so the mediation ability strengthens greatly owing to adopted above-mentioned booster-type structure.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the sectional view according to the pipeline drainer that the utility model proposes.

As shown in Figure 1, this pipeline drainer comprises inflator 1, one way valve 2, gas receiver 3, vent valve 4 and air escape cock 5.Inflator 1 is made up of the depression bar 13 of cylindrical shell 11 and band pad 12.One way valve 2 comprises narrow meshed sealing rubber ring 21 and the cross needle-valve 22 that links to each other with the inflator gas outlet, thereby make gas can not return inflator again, one way valve is contained in the rear portion of position-limiting tube 23, in the position-limiting tube front portion vent valve 4 is housed, vent valve matrix 41 rear portions have the pore 42 along its longitudinal axis, pore 42 is communicated with gas receiver 3 by radial section 43 in the matrix front portion, and the matrix front end has rubber pad 44.Gas receiver 3 comprises cylindrical shell 31, and cylindrical shell 31 front, center have a conduit 32 to be in communication with the outside, and cylinder back-end links to each other with rear cylinder body 24 with thread forms, and by rubber ring 33 sealings.Air escape cock 5 comprises elastic mechanism 51 and rod-type valve 52, and this valve can make the limit valve rear portion be in communication with the outside or be isolated, and when elastic mechanism was not received the pressure of arrow A direction, rod-type valve 52 was hedged off from the outer world position-limiting tube and comes.When inflator was inflated, the gas that comes out from one way valve made vent valve 4 reaches and blocks conduit 32.When air escape cock 5 is activated, the position-limiting tube rear portion is in communication with the outside this space pressure is reduced, because differential pressure action, vent valve 4 just moves backward along arrow B direction speed, cause conduit to be opened, gases at high pressure in the gas receiver 3 for cooperating with the pipeline opening that will be dredged, in catheter proximal end have connected a joint 6 with larger caliber in the present embodiment from the ejection of catheter proximal end mouth.
