Embodiment Construction
[0017] Such as figure 1 , figure 2 shown. Diaphragm check valve consists of diaphragm 1 and diaphragm holder 2. The assembly position on the lower surface of the diaphragm is bonded to the assembly position on the upper surface of the diaphragm holder. The working edge of the upper surface of the diaphragm is in close contact with the working edge of the lower surface of the diaphragm holder, thereby playing a sealing effect. When a substance passes through, the diaphragm is pushed apart. When the substance passes through, the diaphragm returns to its original position under its own elastic force to realize automatic sealing.

The invention provides a diaphragm type one-way valve, which is applied to the occasions for conveying materials discontinuously and uni-directionally to achieve that a passage is closed automaticallywhen the conveying of the materials is stopped. The diaphragm type one-way valve can also be applied to the occasions of floor drains and the like, and is particularly suitable to be applied to a straight-through toilet in sitting or squatting toilets and provides a novel drain valve for the straight-through toilet. Therefore, after relieving oneself, the remaining dirt is basically flushed and cleaned while one washes hands. If necessary, the remaining dirt is flushed away by jet flow water columns. The water used for flushing the toilet is quite little to achieve the advantages of water saving, emission reduction, money saving, deodorization, convenient use and low cost. The characteristics of water saving and emission reduction of the diaphragm type one-way valve are suitable for the requirements on building a resource-saving and environment-friendly society.
Description
technical field [0001] cleaning tools Background technique [0002] Most of the check valves currently used are spring type, hand type, pedal type or counterweight type. The structure is more complicated and inconvenient to use. [0003] The currently used sitting or squatting toilets all need to consume a large amount of water for flushing. The water consumption of an ordinary sitting toilet is about 9-11 liters once. The 3 / 6 liter of water-saving toilet that implements at present flushes 3 liters of urine water, flushes 6 liters of stool water. A squat toilet flushes the same amount of water as a seated toilet. The currently used toilet has a complex structure, high manufacturing cost, and takes up a lot of space. With the development of the economy, the improvement of people's living standards, and the acceleration of rural urbanization, the demand for water resources is bound to increase. my country is a country seriously short of water, and water resources are bec...
