Abstract

The utility model aims to solve the problem of non-ideal use effect of an existing pipeline dredger, and provides a pipeline dredger which is simple to operate and convenient to use. The pipeline dredger comprises a steel cylinder, a pulling rod, a piston check valve, a one-way valve, an overflow pipe and a sealing gasket. The pipeline dredger is characterized in that the piston check valve (2) is mounted in the steel cylinder (3), the lower end of the pulling rod (1) is connected with the piston check valve (2), an inlet is formed in the lower portion of the steel cylinder (3), the one-way valve (4) is mounted on the upper portion of the inlet of the steel cylinder (3), the overflow pipe (6) is mounted on the upper side of the steel cylinder (3), a sealing ring (5) is pasted at the lower end of the steel cylinder (3), water can only enter the piston check valve, the one-way valve stops the water from flowing back, the pulling rod is connected with the piston check valve, and the piston check valve is mounted in the steel cylinder and can vertically move.

Description

Pipeline drainer

Technical field:

The utility model relates to a kind of maintenance tool, is specially a kind of pipeline drainer.

Background technology:

Existing pipeline drainer adopts machinery or malleation mode to dredge, poor effect.

Summary of the invention:

The utility model overcomes above-mentioned existing technical deficiency, provides a kind of simple to operate, easy to use, adopts the pipeline drainer of principle of negative pressure.

The utility model by the obstruction sucking-off in pipeline, plays pipe-dredging effect with principle of negative pressure.

The utility model is realized by following technical scheme: a kind of pipeline drainer, comprise steel cylinder, pull bar, piston check (non-return) valve, flap valve, bleed off pipe, sealing mat, it is characterized in that piston check (non-return) valve (2) is contained in steel cylinder (3), pull bar (1) lower end connects piston check (non-return) valve (2), import is left in steel cylinder (3) bottom, flap valve (4) is contained in steel cylinder (3) above import, bleed off pipe (6) is contained in steel cylinder (3) upside, it is following that sealing ring (5) is bonded at steel cylinder (3), piston check (non-return) valve can only be intake, flap valve stops water to reflux, pull bar connects and piston check (non-return) valve, piston check (non-return) valve is contained in can be up and down in steel cylinder, steel cylinder upside is equipped with bleed off pipe, lower end adhesive seal circle.

During use: first upwards pull pull bar (1) to make piston check (non-return) valve (2) increase, flap valve (4) is opened by negative pressure, and obstruction enters in steel cylinder (3); Then downward pushing drawing rod (1), flap valve (4) cuts out automatically, and obstruction enters piston check (non-return) valve (2), more upwards pulls pull bar (1), making piston check (non-return) valve (2) promote dirt rises from bleed off pipe (6) discharge, repeatedly operation.

The utility model is simple to operate, is applicable to the sewer line dredging use that family stops up.

Accompanying drawing explanation:

Accompanying drawing is the utility model structural representation:

In figure: 1, pull bar, 2, piston check (non-return) valve, 3, steel cylinder, 4, flap valve, 5, sealing ring, 6, bleed off pipe.

The specific embodiment:

Below in conjunction with drawings and Examples, invention is further described.

The utility model as shown in drawings, comprise steel cylinder, pull bar, piston check (non-return) valve, flap valve, bleed off pipe, sealing mat, piston check (non-return) valve (2) is contained in steel cylinder (3), pull bar (1) lower end connects piston check (non-return) valve (2), import is left in steel cylinder (3) bottom, flap valve (4) is contained in steel cylinder (3) above import, bleed off pipe (6) is contained in steel cylinder (3) upside, it is following that sealing ring (5) is bonded at steel cylinder (3), piston check (non-return) valve can only be intake, flap valve stops water to reflux, pull bar connects and piston check (non-return) valve, piston check (non-return) valve is contained in can be up and down in steel cylinder, steel cylinder upside is equipped with bleed off pipe, lower end adhesive seal circle.
