Abstract

The utility model belongs to the indoor sanitary institution, relating to a non-stink anti-overflowing reverse valve. The utility model mainly solves the problem that the water-returning box of the existing drainage pool overflows the water caused by clogging and in order to make the water-returning box discharge the water quickly, a non-stink cover is removed, and the stench in the sewer overflows outwards. The non-stink anti-overflowing reverse valve is composed of a filter net which is provided with an urgent drainage hole and a non-stink shutter which is controlled by a float connecting rod. The water level of the basin can be effectively controlled by the non-stink anti-overflowing valve under the driving of the water in the basin. Under the condition of general clogging of the foreign matter filtration, the water can be discharged quickly, and the stink can be prevented.

Description

Non-stink anti-overflowing reverse valve

The utility model belongs to a kind of indoor sanitary fittings.Be placed in the floor drain shell in the family kitchen sink.The sewage that is used for preventing floor drain from being stopped up by the foreign material of sewage and causes overflows sink and prevent that the foul smell of sewer pipe from emerging from floor drain.

Floor drain in the existing family kitchen sink has obstruction slightly, and sewage just overflows outside the pond, sometimes for preventing that the deodorization button bowl that stops up in the floor drain from taking away, though solve part foreign material blockage problem, the foul smell in the sewer pipe is really emerged very big, contaminated environment influences people's health.

This novel shortcoming that overcomes former floor drain existence.Under the situation of not destroying former floor drain shell and original building structure, easily former floor drain is transformed, reach and make floor drain be difficult for being stopped up, the purpose of smooth and easy draining and tight deodorization by the foreign material in the sewage.

This novel " autocontrol deodorization flowover-proof type back-water valve (BWV) " of saying is made with plastics and metal.

Accompanying drawing be " autocontrol deodorization anti-overflow back-water valve (BWV) structure, below with reference to description of drawings:

Be connected an end of lever (2) with a float (1), the other end is connected above the male-type double-edged fine-toothed comb (5) at the anxious mouth of a river (4) down of band upright post type hollow type, be fulcrum (3), one hole (6) is arranged in the middle of the male-type double-edged fine-toothed comb (5), pass a connecting rod (7), the top of connecting rod (7) is connected on the middle position of lever (2), and the bottom of connecting rod (7) is fixed a deodorization and buckled bowl (8).When sink was arrived in the effluent discharge of upper pool, float (1) can rise and fall according to the size of sink sewage quantity, and by lever (2) drivening rod (7), following deodorization button bowl (8) is opened and closed up and down.Be that the sewage quantity deposited of sink is big, float (1) floats height, drives lever (2) and connecting rod (7), and deodorization button bowl (8) open amount is just big, otherwise then little.The open amount of deodorization button bowl (8) and the required discharge value of sewage adapt.During the sewage emptying, float (1) can fall, and presses down connecting rod (7) by lever (2), and deodorization button bowl (8) is buckled in the ring-like recessed formula water seal (9) of the interior bottom of former floor drain (11) firmly, has sealed foul smell.

On male-type double-edged fine-toothed comb (5), communicate in the mouth of a river (4) and the floor drain under anxious in conjunction with upright post type hollow type, when sewage quantity is big when being stopped up by the foreign material in the sewage in order to convex double-edged fine-toothed comb (5) or in the sink, sewage just can flow in the floor drain (11) from the vertical strip filter screen (10) of the anxious mouth of a river (4) one sides down of upright post type hollow type, buckles the following effluent discharge gap that has increased of bowl (8) by the deodorization that lifted by float (1) and connecting rod (2) and drains rapidly.The top side in the anxious mouth of a river (4) down of column type hollow type is that vertical strip filter screen (10) generally is the sinking shape because of the foreign material in the sewage in sewage, is all stopped up so vertical strip filter screen (10) is generally very difficult, to guarantee effluent discharge in any case.

Lay " deodorization anti-overflow back-water valve (BWV) " floor drain compare with former floor drain, have draining more smooth, not Du advantage.The sealing foul smell is tighter, original floor drain is often blocked unconsciously in effluent discharge, sewage is overflowed outside the sink, people are often passive to the cleaning of foreign material in the sewage in the case, the floor drain that " deodorization anti-overflow back-water valve (BWV) " is installed can not produce above-mentioned phenomenon, to the cleaning of foreign material in the sink also with the people just.

Should take away flat type double-edged fine-toothed comb in the original floor drain and deodorization bowl when laying autocontrol deodorization anti-overflow back-water valve (BWV).

Accompanying drawing drawing explanation: 1, float, 2. bar bar, 3. fulcrum, the 4. anxious mouth of a river down of upright post type hollow type.5. male-type double-edged fine-toothed comb, 6. centre bore, 7. connecting rod, 8. deodorization button bowl, 9. ring-like recessed formula water seal.10. vertical strip filter screen.11, former floor drain.

Claims

1, a kind of autocontrol deodorization anti-overflow back-water valve (BWV) is characterized in that being made up of the anxious foreign material filter screen at the mouth of a river down deodorization button bowl and a generation of a float control.
