Abstract

The utility model provides a portable and practical pipeline dredger for buildings, composed of a plastic plug bag, an air injecting needle, a water injecting opening, a conduit, a tee joint with a switch, an air inflating valve, a water pipe joint, etc. The dredger has a portable structure. Air pressure or hydraulic pressure can be optionally adopted as power to carry out dredging sewers. The dredging by the adoption of air pressure or hydraulic pressure is easy to operate with an extensive application scope. The utility model is especially suitable for dredging pipelines with a plurality of bends and pipelines without dredging openings at the deep parts. The dredger is practical and has low cost and is a domestic preparing article for residents living in buildings.

Description

Hydraulic pressure, the dual-purpose pipeline drainer of air pressure

The utility model relates to a kind of building sewer dredging device, particularly a kind of optional instrument of dredging with hydraulic pressure or air pressure.

The obstruction of building sewer is building resident's a puzzlement greatly, China's utility model patent has been announced a kind of " air-pressure duct dredge ", and (application number: 94217614.6) advantage of this dredge is that suitable conduit bore scope is wide, stops up to have for many bends and deep and dredges effect preferably.Its shortcoming is, the difficult tolerance that adds of grasping the vent plug capsule, and aerating is few, then the tight mouth of pipe of plug; Aerating can be burst the plug capsule too much.In addition, then can not use as if no inflator.

The purpose of this utility model is, the inventor of " air-pressure duct dredge " has carried out having the improvement of important breakthrough, the pipeline drainer that the utility model provides at the shortcoming and defect of own former patented technology, both can adopt air pressure, also can adopt hydraulic pressure is power, and selectivity is wide, uses very convenient, in addition, when inflating, air pressure is controlled automatically, can not burst plug capsule (4).

The utility model is to realize like this, make a pipeline drainer, chew (8) water pipe head (9) and be connected to form with inflating respectively by the three-way connection (7) of the gas injection pin (2) that interlinks successively, water filling port (3), plug capsule (4), conduit (6), belt switch, rotate the switch on the three-way connection, can select hydraulic pressure or air pressure for use is power, gas injection or water filling in the sewer pipe that stops up.When gas injection or water filling, air pressure or hydraulic pressure rise by rubber-like plug capsule and become a stopper greatly, clog pipeline opening, and water or gas can not be released, along with hydraulic pressure or air pressure increase, up to tamper is washed away.

Accompanying drawing is a structural representation of the present utility model

Below in conjunction with accompanying drawing the utility model is described in further detail, make one Hydraulic pressure, the dual-purpose pipeline drainer of air pressure, it by gas injection pin (2), water filling port (3), The threeway (7) of plug capsule (4), pipe joint (5), conduit (6), belt switch successively Interlink, two other joint of threeway is chewed (8), water pipe head with inflating respectively (9) interlink. A gas injection pin (2) formula alive (such as engage thread) and water filling port (3) Connect, when adopting the hydraulic pressure dredging, then back out for subsequent use. One has flexible gear gas Sebific duct (10) is enclosed within on the blind pipe at gas injection pin (2) rear portion, flexibly covers gas injection Hole (1), injecting hole (1) communicates with blind hole in the gas injection pin.

Plug capsule (4) is a utricule of being made by elastomeric material (such as rubber), with Conduit (6) bore that its upper end links to each other is greater than the water filling port (3) that links to each other with its lower end Bore. Inflate and chew (8) and bicycle air nozzle structure roughly the same.

During dredging pipeline, must be the whole sewer pore of putting into of plug capsule (4), make plug capsule (4) upper end not expose the mouth of pipe, when adopting the air pressure mediation, gas injection pin (2) connects on water filling port (3), close the switch in the threeway, chew gas injection in (8) to inflating with bicycle pump, air communication is crossed conduit (6) and is entered plug capsule (4), plug capsule (4) is heaved resemble a stopper to clog the mouth of pipe, when reaching certain air pressure, air communication is crossed the inner orifice of gas injection pin (2) and is outwards pushed open between retaining gas sebific duct injection plug capsule and the tamper from injecting hole (1), air pressure in this space constantly increases, and up to blowing logical tamper, realizes the mediation effect; When adopting the hydraulic pressure mediation, the principle method substantially roughly the same, difference is during use, before plug capsule (4) is put into the downcomer hole, earlier the gas injection pin that connects on water filling port (3) is backed out, opens the switch in the threeway, when being connected on, water pipe head (9) opens tap on the tap, because conduit (6) bore is greater than the water filling port bore, hydraulic pressure can make plug capsule (4) bulge in advance, resembles a stopper and clogs the mouth of pipe, it is excessive that the water that injects sewer pipe can not upwards be let out, up to tamper is washed away.No matter adopt air pressure or hydraulic pressure, in case behind the pipe-dredging, close tap, or stopping to inflate and opening three-way cock, plug capsule (4) will shrink recovery automatically, can take out from sewer pipe easily.

The utility model is through practical proof, except the obstruction that stone, cement are formed is difficult to prove effective, stop up and effectively to dredge for general family expenses sewer, particularly can adopt air pressure and hydraulic pressure respectively is that power is dredged, just, provide alternative and improved the mediation effect dissimilar obstructions.The utility model is simple in structure, and is with low cost, can become family of building resident family standby.

Embodiment:

Make a Φ 40mm, be about the rubber plug capsule of 200mm, there is a tapped engineering plastics water filling port (Φ 5mm) lower end, and is furnished with a copper gas injection pin that is with the retaining tracheae, then takes off standby when adopting hydraulic pressure.Plug capsule upper end is connected with the flexiplast conduit of Φ a 12 * 1.2mm, and the conduit other end is connected with the engineering plastics three-way connection of a belt switch, and two other joint of three-way connection connects to inflate respectively and chews and water pipe head.Inflating has one section connecting tube before chewing.

Claims (1)

1, a kind of pipeline drainer is interlinked successively by water filling port (3), plug capsule (4), conduit (6), it is characterized in that:

One of them joint of the threeway of a, a belt switch (7) and conduit interlink, and two other joint is chewed (8) and water pipe head (9) interlinks with inflating respectively.

B, also have one can with water filling port (3) formula of living connect (as thread connection) gas injection pin (2), a rubber-like retaining gas sebific duct (10) is enclosed within on the blind pipe at gas injection pin (2) rear portion, flexibly covers injecting hole (1).

C, plug capsule (4) are utricules of being made by elastomeric material, and conduit (6) diameter that links to each other with its upper end is greater than water filling port (3) diameter that links to each other with its lower end.
