Abstract
The utility model discloses a kind of automatic back-flow preventer of drain of kitchen, belong to Water and Waste Water Engineering field.It is mainly set up one in drain of kitchen is installed and newly-designed automatically prevents back valve between elbow under main downcomer and washbasin, for preventing the backflow of sewage so that drain of kitchen is mainly by main downcomer, automatically prevent back that valve, elbow, the indoor pair structure such as downcomer, washbasin are constituted.This utility model has simple to operate, low cost, the feature such as effective, can be widely used for the backflow of anti-drain of kitchen.
Description
Technical field
The present invention relates to a kind of automatic back-flow preventer of drain of kitchen, belong to Water and Waste Water Engineering field.
Background technology
Currently, skyscraper gets more and more, owing to pipeline is meticulous, crook design is unreasonable, foreign material alluvial, especially cold
Season is affected owing to easily being lumpd by greasy dirt, and sewer pipe easily turns alluvial blocking at sharp turn at bottom and causes blowdown freely, thereby tends to
It is back to main sewer pipe in the bottom building of UNICOM, especially owing to blocking can cause sewage to assemble rising in pipeline
Sometimes family is medium-term and long-term unmanned, large amount of sewage can be caused to enter, make its resident family suffer untold misery.How to prevent drain of kitchen from preventing for this
Backflow has become a difficult problem urgently to be resolved hurrily.
It is an object of the invention to provide a kind of automatic back-flow preventer of drain of kitchen, the present invention has simple to operate, one-tenth
The features such as this is low, effective, can be widely used for the backflow of anti-drain of kitchen.
Summary of the invention
It is an object of the invention to provide a kind of automatic back-flow preventer of drain of kitchen, in order to promote it at kitchen sewer water
Application in road anti-return.
The present invention is achieved in that
1. the automatic back-flow preventer of drain of kitchen, it is characterised in that: increase in general kitchen sewer is installed
One newly-designed prevents back valve automatically so that drain of kitchen is mainly by main downcomer, automatically prevent back that valve, elbow, indoor pair descend water
The structures such as pipe, washbasin are constituted.
2. automatically prevent back that valve is installed between the elbow under main downcomer and washbasin described in, its Inlet and outlet water bore and indoor
Downcomer is suitable, the middle part that its a length of pipe diameter is more than 4 times except the end put down constant in addition to then the most outwards heave from tube side wall, its bore
Become larger, outside more than the flaring 1cm of side wall, above tube wall upwards flaring make pipe inner height be Inlet and outlet water bore 2 times
Above, set, heaving top, the circular open with cover that a bore is suitable with Inlet and outlet water bore, put into a bore more than intake-outlet
The plastics in footpath or rustless steel ball, lid is lower to be installed one and blocks rod, is only limitted in a side ducts of rod of blocking for controlling ball
Motion.This anti-reflux valve is installed between the elbow under main downcomer and washbasin, automatically prevents back valve circle ball entrance upwards, put into
Ball, is placed in nearly elbow side by control ball during lid lid.
3. the main downcomer described at washbasin and is prevented back between valve at more than 10cm, elbow by diameter automatically, and water pipe is
PVC plastic, newly sets and automatically prevents back that valve, washbasin material are as PVC plastic, rustless steel etc..
Accompanying drawing explanation
Fig. 1 is a kind of drain of kitchen automatic back-flow preventer profile
In figure: the most main downcomer, 2. washbasin, 3. indoor secondary downcomer, 4. elbow, 5. automatically prevent back valve
Beneficial effect
It is an object of the invention to provide a kind of drain of kitchen back-flow preventer, owing to automatic anti-reflux valve can be carried out certainly
Moving and prevent back, when indoor washbasin has underwater drainage, the ball in recirculation control device can move to, due to the thrust of water, rod of blocking
Place, ball will not block outlet, and water will be by flowing to main sewer pipe above ball, and main sewer pipe occurs because of blocking
During backflow, ball can be due to the pushing motion of recirculation water by stifled for pipeline real closing, to prevent the backflow of sewage.High level is built
Build be positioned at bottom which floor, its drain of kitchen use anti-return design, backflow phenomenon can be stoped to occur so that main sewer pipe
Sewage is further up, thus increases pressure, when pressure reaches a timing, and just many meeting natures are unobstructed.Will when there being sewage backflow
Its closing volume passage voluntarily, effectively to prevent sewage backflow so that main pipeline sewage is further up, thus increases pressure,
When pressure reaches a timing, and just many meeting natures are unobstructed.The present invention has simple to operate, low cost, the feature such as effective.The present invention
It is designed as the backflow of anti-drain of kitchen and provides reliable technical scheme.
Detailed description of the invention
Below by detailed description of the invention, the present invention is described in further detail.
In following embodiment, method therefor is conventional method if no special instructions.
1. implementation:
1. the automatic back-flow preventer of drain of kitchen, uses automatically preventing back of the design of material such as PVC plastic, rustless steel
Valve gear, its Inlet and outlet water bore and indoor sewage pipe are suitable, the middle part that its a length of pipe diameter is more than 4 times except the end put down constant in addition to then from
Tube side wall is the most outwards heaved, and its bore becomes larger, outside more than the flaring 1cm of side wall, above tube wall upwards flaring make
Pipe inner height is more than 2 times of Inlet and outlet water bore, opens heaving the circle with cover that top sets a bore suitable with Inlet and outlet water bore
Mouthful, to put into a bore and be more than plastics or the rustless steel ball of Inlet and outlet water bore, lid is lower installs a rustless steel steel rod, is used for controlling circle
Ball is only limitted in a side ducts of steel rod motion.During installation, this being prevented back automatically, valve is installed under main downcomer and washbasin curved
Between Tou, automatically prevent back valve circle ball entrance upwards, put into ball, during lid lid, control ball is placed in nearly elbow side so that kitchen
Room sewer is mainly by main downcomer, automatically prevent back that valve, elbow, the indoor pair structure such as downcomer, washbasin are constituted, when indoor washbasin
When having underwater drainage, the ball in recirculation control device can move at steel rod due to the thrust of water, and ball will not block water outlet
Mouthful, water will by flowing to main sewer pipe above ball, and main sewer pipe occur because of blocking backflow time, ball can due to time
The pushing motion of flowing water and real close stifled for pipeline, to prevent the backflow of sewage.
Claims (2)
1. the automatic back-flow preventer of drain of kitchen, it is characterised in that: in general kitchen sewer is installed, increase by one new
