Description

A kind of air pressure dredging seal head

Technical field

The utility model relates to pipe-dredging technical fields, and in particular to a kind of air pressure dredging seal head.

Background technique

In daily life, sewer pipe is easily blocked by dirt, therefore occurs pipelines dredge in the market, profession pipe What road dredging personnel were often used is a kind of mechanical dredging machine, it is the obturator twisted out in pipeline by mechanical rotation reamer, this The defect of kind of machine is that it is at high cost that structure is complicated than cumbersome, if asking the profession dredging inevitable time-intensive, expensive of team, there are also one is than More easy dredging tool is commonly called as water and pulls out son, although the tool structure is simple, at low cost, its suction is smaller, and dredging effect is not Ideal, and often there is dirty water to flash when in use, it is very unhygienic, there is the patent No. 201621092104.0 to disclose a kind of air pressure at present Seal head to be dredged, is increased by air pressure, air valve is flicked, high pressure draught is got, makes to be flown up by the hydraulic pressure in blocked pipeline, and One shock wave is generated, forms powerful explosive force in liquid internal, the sundries that is blocked is impacted, to reach the mesh of unclog the pipe , but when it flicks air valve, will cause certain influence, it would be highly desirable to it improves.

Utility model content

The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, and design is closed Seal head is dredged in reason, air pressure easy to use, is increased by air pressure, cross open is strutted, high pressure draught is got, to impact Be blocked sundries, achievees the purpose that unclog the pipe, and structure is simple, and at low cost.

To achieve the above object, the technical solution adopted in the utility model is：It include ventilation end, closed end, gas chamber and No.1 retainer plate, the one end at the ventilation end are fixed with No.1 retainer plate, and the other side of the No.1 retainer plate is equipped with closed end, It is wrapped with gas chamber on the outside of the closed end, described gas chamber one end is folded between closed end and No.1 retainer plate, described No.1 retainer plate is fixedly connected with closed end, and the other end of gas chamber is fixed on side of the closed end far from ventilation end one end, institute Cross open is offered on the outer end for the gas chamber stated, and several ventholes are offered on the side wall of the closed end.

Further, the gas chamber outer end wall is equipped with No. two retainer plates, and No. two retainer plates are solid by self-tapping screw It is scheduled on closed end

After adopting the above structure, the utility model has the beneficial effect that：A kind of air pressure dredging sealing described in the utility model Head is increased by air pressure, and cross open is strutted, and high pressure draught is got, and the sundries so that impact is blocked reaches the mesh of unclog the pipe , structure is simple, and at low cost, and the utility model has structure simple, setting rationally, the advantages that low manufacture cost.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the side view of the utility model.

Description of symbols：

Ventilation end 1, closed end 2, gas chamber 3, No.1 retainer plate 4, No. two retainer plates 5, cross open 6, ventholes 7.

Specific embodiment

The utility model will be further described below with reference to the accompanying drawings.

Referring to as shown in Figure 1 and Figure 2, the scheme that present embodiment uses is：It includes ventilation end 1, closed end 2, gas One end of room 3 and No.1 retainer plate 4, the ventilation end 1 is welded with No.1 retainer plate 4, the No.1 retainer plate 4 it is another Side is equipped with closed end 2, is wrapped with gas chamber 3 on the outside of the closed end 2, described 3 one end of gas chamber is folded in closed end 2 and No.1 Between retainer plate 4, the No.1 retainer plate 4 is bolted to connection with closed end 2, and the other end of gas chamber 3 is fixed on envelope On side of the closed end 2 far from ventilation 1 one end of end, the outer end wall of the gas chamber 3 is equipped with No. two retainer plates 5, and No. two retainer plates 5 It is fixed on closed end 2 by self-tapping screw, after which sequentially passes through No. two retainer plates 5,3 outer end wall of gas chamber, is screwed on Cross open 6 is offered on the top of closed end 2, the outer end of the gas chamber 3, offers number on the side wall of the closed end 2 A venthole 7.

The working principle of this specific embodiment:：When in use, air pressure dredging seal head is connect with pressure source, pressure gas Body enters in gas chamber 3 through ventilation end 1, air inlet 7, and under the effect of the pressure, gas chamber 3 moment swell, atmospheric pressure value reaches certain value When, cross open 6 is opened, and pressed gas is discharged to 6 direction of cross open, and a large amount of high pressure draught is got, and is the pipeline that is blocked In hydraulic pressure fly up, and generate one shock wave, form powerful breaking out force in liquid internal, impact the sundries being blocked, Achieve the purpose that unclog the pipe.

After adopting the above structure, present embodiment has the beneficial effect that：A kind of air pressure described in present embodiment Seal head is dredged, is increased by air pressure, cross open is strutted, high pressure draught is got, and the sundries so that impact is blocked reaches dredging The purpose of pipeline, structure is simple, and at low cost, and the utility model has structure simple, and rationally, it is excellent that cost of manufacture is low etc. for setting Point.

The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope should all cover in the scope of the claims of the utility model.
