The purpose of this utility model just provides the anti-water that returns that a kind of sewer mouth and side institute urinal are used, the anti-unidirectional protection valve that returns flavor.
The utility model is achieved in that it is made up of valve body, spring, mounting ear, valve gap, it is characterized in that; Be connected with a spring between valve gap and the valve body, mounting ear is contained in the valve body top; On valve body lower portion edge and valve gap, magnet is housed.
The utility model has the advantages that; Not only when sewer stopped up, it was indoor to prevent effectively that sewage from returning, and can also prevent the odor pollution air for it, simultaneously simple in structure, easy to manufacture.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
Schematic diagram when Fig. 1 is installed in side institute for the utility model.
Fig. 2 is the utility model structural representation.
1 is mounting ear among the figure, and 2 is valve body, and 3 is spring, and 4 is bearing pin, and 5 is magnet, and 6 is valve gap, and 7 is urinal.Mounting ear, valve body, valve gap can be made with rigid plastics or cast iron, bearing pin and spring can be made with carbon steel or stainless steel, mounting ear is screwed on the valve body with bolt, spring is hung on valve body and the valve gap, valve gap is contained on the valve body and puts on bearing pin, valve body, valve gap according to sewer pipe thickness difference be made into different-diameter so that be fit to various pipelines.With the valve body urinal sewer pipe of packing into, mounting ear is contained on the cement floor with stone bolt, during normal the use, the impulse force of water is opened valve gap, and class is just poured sewer pipe, when pipeline takes place to stop up, return water pressure valve gap is closed the jail, it is indoor sewage to be returned, and resident family also can in time find, in time repairs.Magnet is in order valve gap and valve body to be fited tight and to establish.This protective valve is contained in the kitchen realizes above-mentioned functions too.Because valve gap is closed at ordinary times, so also can prevent the odor pollution air.
