Abstract
The utility model provides a diaphragm-type one-way valve, which is applied to places providing intermittent unidirectional delivery services, with the aim of automatically closing the passage when delivery ends. The utility model can be used in places such as floor drains and the like, is particularly suitable for use in straight-through closestools of seat-type and squatting type toilets, and provides a novel blowdown valve. The diaphragm-type one-way valve can ensure that water drips down people's hands for sanitary purposes and carries residual dirt away in a roughly complete manner, and if necessary, allows for direct cleansing by water-jet means. The utility model ensures that closestool cleansing consumes an extremely small amount of water, achieves the effects of water saving, drainage water reduction, money saving, and sterilization, and has the advantages of convenient use and low cost. Characterized by water saving and drainage water reduction, the utility model meets the requirements for building a resource-efficient and environment-friendly society.
Description
Technical field
Sanitaryware
Background technology
At present the one way valve of using mostly is spring, hand plate type, foot-operated or counter weight type etc.Structure is complicated, uses inconvenient.
Sitting posture of using or squatting pot all need consume a large amount of water flushings at present.The about 9-11 liter of the expendable water supply volume of common sitting type toilet seat.3/6 liter of water-saving toilet carrying out dashes 3 liters of urine waters at present, dashes 6 liters of stool waters.The washing water quantity and the sitting type toilet seat of squatting pot are similar.The present toilet structure complexity of using, the manufacturing cost height, it is big to take up room, and the evaporating, emitting, dripping or leaking of liquid or gas phenomenon often appears in water tank.Along with expanding economy, the raising of living standards of the people, the quickening of urbanization of villages process certainly will be increasing to the demand of water resource.China is the country of serious water shortage, and water resource is more and more poorer at present.The conserve water resource has become the task of top priority.The toilet water accounts for 40% of living water use, and reducing the toilet water supply volume will have remarkable effect to pressure and the minimizing urban sewage discharge of alleviating water resource.
Summary of the invention
The purpose of this invention is to provide a kind of unidirectional backstop.Be applied in the occasion of interrupted unidirectional transportation of substances, automatic closing passage when realizing stopping transportation of substances.
Form by diaphragm and diaphragm frame for finishing the diaphragm type one-way valve that goal of the invention designs.The platform bonding diaphragm at local place, bottom surface.The working edge of diaphragm upper surface is close to the working edge of diaphragm frame soffit, plays sealing process thus.Diaphragm is an elastomeric material.When material passed through, diaphragm was open.After material passed through, diaphragm returned to original position under the elastic force effect of self, realized from movable sealing.
The present invention can be applicable to occasions such as floor drain.Be particularly suitable for being applied to the straight-through toilet (no deodorization bend pipe, sewage draining exit docks with sewer, the daily life sewage gutter collects in the sewage draining exit place) in sitting posture and the squatting pot.For it provides a kind of new-type sewage draining valve.Make that the flush toilet water is few.Realized water saving, reduction of discharging, saved money, deodorization, easy to use, cost is low.
Diaphragm type one-way valve is positioned at the sewage draining exit place of toilet.When relieving oneself, excreta is pushed diaphragm open.Excreta enters sewer automatically.Under the elastic force effect of diaphragm self, return to original position subsequently, realize from movable sealing.Open the ejector of toilet top, when washing one's hands the residual dirt in the toilet is rinsed well substantially.Directly wash away residual dirt with the jet water column in case of necessity, water is few.Dash the about 0-0.1 liter of urine water, dash the about 0-0.4 liter of stool, economize on water more than 95% than 3/6 liter of water-saving toilet.
The present invention is applied to straight-through toilet and has following characteristics:
1, water saving.Wash one's hands and equal towards toilet.When washing one's hands, the residual dirt in the toilet is washed down substantially.Directly wash away residual dirt with the jet water column in case of necessity, water is few.Dash the about 0-0.1 liter of urine water, dash the about 0-0.4 liter of stool, economize on water more than 95% than 3/6 liter of water-saving toilet.
2, reduce discharging.Reduce quantity of wastewater effluent, reduce the sewerage treatment load.
3, save money.The cheap time spent economizes when buying.Simple in structure, price is cheap.Every month few towards the water rate of toilet.Reduce the construction cost of water factory, reduced the construction cost of Wastewater Treatment Plant, reduced the sewerage treatment expense.
4, deodorization.Back foul gas phenomenon after the water seal of conventional toilet deodorization is evaporated some does not appear.
5, easy to use.Pull or pin is stepped on without hand, open and sealing is automatically and carries out.
6, low cost of manufacture.Simple in structure, materials are few, easily processing.

The specific embodiment
As shown in Figure 1 and Figure 2.Diaphragm type one-way valve is made up of diaphragm 1 and diaphragm frame 2.The platform bonding diaphragm at local place, bottom surface.The working edge of diaphragm upper surface is close to the working edge of diaphragm frame soffit, plays sealing process thus.Diaphragm is an elastomeric material.When material passed through, diaphragm was open.After material passed through, diaphragm returned to original position under the elastic force effect of self, realized from movable sealing.
