Description

Blowdown epidemic prevention valve

Technical field

The utility model belongs to a kind of blowdown epidemic prevention valve.

Background technology

In life, people smell one unpleasant stink in the collecting well of the highway of being everlasting, residential quarters, park, factory building, and this stink is exactly poisonous, the unpleasant gas that gives out to air by collecting well from underground sewage.In the construction in the past, the collecting well pipeline is not taked any deodorization measure, and people often therefrom infect vaccine and be sick, and collecting well become breeding, the breeding ground of insects such as mouse, mosquito, cockroach, has accelerated transmission of disease.

Technology contents

The purpose of this utility model provides a kind of blowdown epidemic prevention valve, utilizes valve block to close automatically, stink can not be flow backwards, and do not overflow contaminated air; Various insects can not pass through simultaneously, play the effect of epidemic prevention.

The utility model is made up of valve gap, valve body, valve block, valve shaft, there is water in-out port at valve body (2) two ends, valve gap (1) is stuck in the draw-in groove at valve body (2) middle part, and valve block (3) is connected with valve body (2) with valve shaft (4), and the interior inclined-plane of valve block (3) and valve body (2) cooperates.The water in-out port of valve body (2) has boss to be connected with blow-off pipe.

The utility model is reasonable in design, and is simple in structure, easily makes, except that the drain function that general drainage pipe is arranged, the deodorization of preventing epidemic, and and underground blow-off pipe same equivalent life is arranged, can with terrace roof drain, the aggregate erection of balcony floor drain, do not have at the water floor drain under the situation of water and play the deodorization effect.It is better to be applied in the collecting well of highway, residential quarters, park, factory building effect.
