Abstract
The utility model relates to a dredger for pipelines, comprising a cylinder and a plunger positioned in the cylinder. The plunger is fixed to a draw rod. One end of the draw rod, which extends out of the cylinder is provide with a handle. The bottom of the cylinder is provided with a through hole and the side wall is also provided with a through hole. The end of the cylinder is sheathed with a valve seat. The relative positions of the valve seat and the two through holes on the cylinder are respectively provided with a first and a second one-way valves.
Description
A kind of drain cleaner relates to the equipment by the fluid pressure cleanser conduit, and domestic residential houses sewer stops up or toilet stops up, and generally the dredging tool that uses is rubber cup.But the suction capactity of rubber cup is limited, and this Chinese patent is disclosed a kind of " drain cleaner " for No. 93240140.6.It is made of the piston of band handle.Handle is a vertical tube, and insert in the capsule as piston its lower end, and be connected firmly, and makes the capsule sealing, and vertical tube inserts on the tube wall of the part in the capsule and has water injection hole, and the handle top is provided with valve.During use tap water is injected in the capsule by handle, make the capsule outside line mutually closely connected with inner-walls of duct.Behind the valve-off, piston is twitched up and down, blocking foreign material in the pipeline can be drawn out of.But this dredging device, the on the one hand sealing of handle and capsule and be connected and be difficult to solve very easily breakage of capsule in the use on the other hand.
The purpose of utility model provides a kind of drain cleaner, its sound construction, and can effectively dredge can ducted obturator.
According to above-mentioned purpose, utility model is taked such technical scheme: this drain cleaner comprises cylindrical shell and is positioned at the piston of cylindrical shell, piston is fixed on the pull bar, the end that pull bar stretches out cylindrical shell is equipped with handle, one through hole is arranged at the bottom of cylindrical shell, it is characterized in that having on the cylinder lateral wall another through hole to be with valve seat in the end of cylindrical shell, the two through hole relative position is equipped with first and second one way valves respectively on valve seat and the cylindrical shell.
During use, this dredging machine valve seat end is inserted by in the plug pipeline, the pulling handle, because the effect of one way valve, thereby in tube, form negative pressure, thus with the obturator sucking-off.When pressing down handle, the fluid of negative pressuren zone is then discharged cylindrical shell from sidewall through one way valve in the tube.
The utlity model has rational in infrastructure firmly, easy to use, the advantage that suction force is big, the obturator in the dredging pipeline easily and effectively.
The structure of utility model is provided by following embodiment and accompanying drawing.
The drain cleaner structural representation that accompanying drawing the utility model proposes for foundation.
As shown in drawings, the main body of this drain cleaner is the cylindrical shell and the valve seat of a band piston.The upper end of cylindrical shell (4) is a cover (3), and handle (2) preferably is housed on the cover.Piston (6) is housed in the cylindrical shell, and piston is fixed on the pull bar (5).Pull bar then stretches out cylindrical shell through cover, and extension is equipped with handle (1).Two hands are held in respectively on handle and the handle during use, easily the pull piston.Respectively have a through hole on the bottom of cylindrical shell and the sidewall.Valve seat (7) is enclosed within the end of cylindrical shell, and first one way valve (8) and second one way valve (9) respectively are housed at the position relative with two through hole on the cylindrical shell.And the direction of the fluid of two one way valves of flowing through is opposite.In order to make this drain cleaner not only have pumping function, and has the pushing function to pipe internal congestion thing.Sidewall at valve seat also can refill.The 3rd one way valve is equipped with the 4th one way valve in valve seat with on the 3rd one way valve same radial.Rotate valve seat during use, make the two through hole on the cylindrical shell relative with the 3rd one way valve respectively with the 4th one way valve, because the single effect of one way valve, push handle, i.e. the pushing effect of achievable pair obturator.If open a through hole again, when the through hole of this through hole bottom cylindrical shell is relative,, also can reach the pull effect to pipe internal congestion thing by control crank in valve seat inside.For this drain cleaner is connected mutually with pipeline better, sucker (10) preferably is housed at the extending part of valve seat.
Claims (5)
