Description

Anti-overflow, smelly, the water saving the lavatory pan non retern valve

The utility model relate to a kind of anti-overflow, smelly, the water saving the lavatory pan non retern valve.

Along with the whole world is industrialized flourish, human demand to water increased severely with day at present, and overweight water resource is dug, exploitation, causes the large tracts of land betrunking of stream, and underground water sharply descends.At the national shortage of fresh water of part, fed through to human existence.Cutout appears in the trunk river of China existing 3/5ths according to statistics, and the lake occurs dry, and 2/3rds big and medium-sized cities underground water occurs and descend.Serious lack of water has been endangered and has been coerced people's life.For using water wisely, people's water-saving water-saving valve that begun one's study is as CN2090396Y disclosed a kind of " lavatory pan anti-overflow, smelly, leaking joint water valve ", though this water-saving valve can be economized on water, because its other parts are many, complex structure, therefore the cost of manufacture height is unfavorable for extensively promoting the use of.

The purpose of this utility model provides the lavatory pan non retern valve of the low anti-overflow of a kind of simple in structure, easy for installation, using water wisely and cost of production, smelly, water saving.

Task of the present utility model is achieved in that this non retern valve, and it comprises a cylinder shape valve made from the rubber of acid and alkali resistance, wherein be provided with two road hangnails, be provided with the flat check mouth of an energy automatic shutter in the lower end of valve body at the middle part of valve outer surface.

Because the utility model has adopted the non retern valve of said structure, therefore compare with background technology, have simple in structure, easy for installation, cost of production is low and advantage such as using water wisely.

The utility model will be further described below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is user mode figure of the present utility model.

As depicted in figs. 1 and 2, non retern valve of the present utility model, it comprises a cylinder shape valve 1 made from the rubber of acid and alkali resistance, be provided with the triangle hangnail 2 that two roads prevent that non retern valve from sliding at the middle part of valve body 1 external surface, two road hangnails 2 4cm of being separated by is provided with the flat check mouth 3 of an energy automatic shutter in the lower end of valve body 1.

As shown in Figure 3, non retern valve 5 of the present utility model is contained in the defecation mouth 6 of water closet 4.When the flushing of dirt water was arranged in the water closet, the check mouth of non retern valve was opened under the effect of gravity, and dirt is discharged; After dirt was discharged, check mouth auto-closing was blocked it up and down, realized the purpose of anti-overflow, smelly and water saving.

Non retern valve of the present utility model can not only be used for water closet, also can be widely used on various crouching type closet bowls or the various floor drain.
