Description

Automatic cleaning water valve

Technical field

The present invention relates to a kind of obstruction that can clean automatically in drain pipe (sewerage) the U type bend pipe, make drain pipe (sewerage) unblocked.

Technical background

The drain pipe that sewage effluent is used in the kitchen of residential building (sewerage), because of giving out dense peculiar smell in the pipeline, so be equipped with a U type bend pipe (elbow) in the ingress of drain pipe (sewerage), hold in the U type bend pipe a certain amount of water is arranged, water plays sealing, the peculiar smell of drain pipe (sewerage) lining is isolated by water, and peculiar smell can not be diffused into bedroom and living area.Owing to often carrying the domestic garbage (foul) of volume in the domestic sewage secretly, when domestic garbage (foul) was flowed through U type bend pipe, because U type bend pipe structure causes that through regular meeting drain pipe (sewerage) stops up, this brought inconvenience for people's life.The present invention provides a kind of automatic cleaning water valve, it be installed in U type bend pipe above, when U type bend pipe stops up, just can clean the obstruction in the U type bend pipe automatically, make U type bend pipe unblocked.

The advantage that the present invention has is: simple in structure, easy for installation, reliable performance, market prospects are wide.

Summary of the invention

The purpose of this invention is to provide a kind of obstruction that can clean automatically in drain pipe (sewerage) the U type bend pipe, automatic cleaning water valve easy for installation.

For achieving the above object, the technological scheme that the present invention takes is: automatic cleaning water valve is made up of water valve and washing apparatus two parts.Water valve is formed (Fig. 1) by water intake 13, water outlet 14, dodge gate 15, floating block 16, movable door-hinge 17, cover plate 18, set screw 19, valve body 20; Washing apparatus is formed (Fig. 2) by cleaning bend pipe 4, adjusting screw 5, retaining screw 6, intake pipe 7, electromagnetism water valve 8, control electric wire 9, singlechip controller 10, metal probe 11, cleaning bend pipe shower nozzle 12; Water outlet 14 is installed on the U type bend pipe water intake 1, cleans the bottom that bend pipe shower nozzle 12 is installed in U type bend pipe, and is not in place as the position, and rotatable adjusting screw 5 is tightened after making its position suitable again, and cover plate 18 has been sealings and metal probe 11 used (Fig. 3) is installed.

The working procedure of automatic cleaning water valve is: domestic sewage flows into water intake 13, because the weight of the gravity of sewage and dodge gate 15 self, dodge gate 15 is in open mode (Fig. 4) at ordinary times, at this moment sewage flows into valve body 20, directly enter U type bend pipe water intake 1 by water outlet 14, enter drain pipe (sewerage) by U type bend pipe exhaust port 3 again; On the U type bend pipe 2 is anti-plugging bolts, is the foul (Fig. 5) that is used for manually cleaning in the U type bend pipe; When the domestic garbage of carrying volume in the sewage secretly (foul) flows into automatic cleaning water valve, U type bend pipe can not normally be discharged, domestic garbage (foul) will be deposited in the U type bend pipe, at this moment U type bend pipe is blocked, sewage is just toward going up, when sewage increases to metal probe 11, singlechip controller 10 detects the resistance change of metal probe 11, electromagnetism water valve 8 is opened, tap water is flowed into by intake pipe 7 and cleans bend pipe 4, by cleaning the directly bottom of obstruction injection in U type bend pipe of bend pipe shower nozzle 12, makes it to be subjected to the hydraulic pressure of tap water, go out U type bend pipe exhaust port 3, enter drain pipe (sewerage); When obstruction was difficult to be cleaned for the moment, water level can continue toward going up, when water level increases to floating block 16, dodge gate 15 is closed, and sewage is plugged, under the effect of hydraulic pressure, obstruction is discharged from U type bend pipe exhaust port 3, enters drain pipe (sewerage), and pipeline is unimpeded thereupon.

Embodiment

The working procedure of automatic cleaning water valve is: domestic sewage flows into water intake 13, because the weight of the gravity of sewage and dodge gate 15 self, dodge gate 15 is in open mode (Fig. 4) at ordinary times, at this moment sewage flows into valve body 20, directly enter U type bend pipe water intake 1 by water outlet 14, enter drain pipe (sewerage) by U type bend pipe exhaust port 3 again; On the U type bend pipe 2 is anti-plugging bolts, is the foul (Fig. 5) that is used for manually cleaning in the U type bend pipe; When the domestic garbage of carrying volume in the sewage secretly (foul) flows into automatic cleaning water valve, U type bend pipe can not normally be discharged, domestic garbage (foul) will be deposited in the U type bend pipe, at this moment U type bend pipe is blocked, sewage is just toward going up, when sewage increases to metal probe 11, singlechip controller 10 detects the resistance change of metal probe 11, electromagnetism water valve 8 is opened, tap water is flowed into by intake pipe 7 and cleans bend pipe 4, by cleaning the directly bottom of obstruction injection in U type bend pipe of bend pipe shower nozzle 12, makes it to be subjected to the hydraulic pressure of tap water, go out U type bend pipe exhaust port 3, enter drain pipe (sewerage); When obstruction was difficult to be cleaned for the moment, water level can continue toward going up, when water level increases to floating block 16, dodge gate 15 is closed, and sewage is plugged, under the effect of hydraulic pressure, obstruction is discharged from U type bend pipe exhaust port 3, enters drain pipe (sewerage), and pipeline is unimpeded thereupon.
