Abstract
The utility model relates to a pipeline valve, specifically speaking is a pollution discharge epidemic prevention valve which comprises a valve body and a valve plate. The utility model is characterized in that the valve body is divided into a front end valve body and a post end valve body, the middle parts of which are movably connected, and the flaring of the back intracavity flaring of the front end valve forms an inclined plane platform, the top of which is provided with a boss, and a valve plate shaft which connects to the valve plate is arranged on the boss and cooperates with the inclined plane platform of the front end valve body, and the two ends are provided with an outlet and an inlet of water gaps. The utility model has the advantages of reasonable design, simple structure, and is provided with the function of epidemic and foul odour prevention, blocking odor refluxing, and preventing mosquitoes and cockroach climbing along the pipe in addition to the drainage function of ordinary drainage pipes. The utility model can have good effects when applied to the collector wells in the highways, residential districts, parks and workshops.
Description
Technical field
The utility model belongs to a kind of pipeline valve, more specifically is 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, screen-like mountain peak dung beetle, 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, and various insects can not pass through simultaneously, play the effect of epidemic prevention.
The technical solution of the utility model is: a kind of blowdown epidemic prevention valve, comprise valve body, valve block, it is characterized in that valve body sub-headend valve body and rear end valve body, the two intermediate active connects, the rear portion inner chamber enlarging of front end valve body, enlarging place forms a ramp platform, at the top of ramp platform one boss is arranged, the valve block rotating shaft is arranged on the boss, the valve block rotating shaft connects valve block, valve block cooperates with the ramp platform of front end valve body, and there is water in-out port at two ends.
For the ease of with being connected of sewer pipe, can make the water in-out port of valve body cylindrical.Valve body is divided into two sections, is the assembling for the ease of whole blowoff valve.Concrete a kind of mode is that the connected mode of front end valve body and rear end valve body is the screw-button knot, and there is sealing ring the junction.The front end water inlet of valve body can connect drainage pipe, and the rear end delivery port can connect the blowdown main road or directly lead to septic tank, collecting well etc.When water passed through, valve block can be opened under the pressure of water, and when there not being current out-of-date, valve block is the meeting auto-closing under the effect of gravity, considered that the too high meeting of density of valve block influence passing through smoothly of water, and valve plate material can use plastic material.Like this, when not having draining in the most of the time, the foul smell of blowoff valve lower end can not reflux,
The utility model is reasonable in design, and is simple in structure, easily make, and except that the drain function that general drainage pipe is arranged, the deodorization of preventing epidemic.It is better to be applied in the collecting well of highway, residential quarters, park, factory building effect.
Description of drawings
Accompanying drawing 1 is the utility model structure sectional view.
Among the figure, 1. front end valve body, 2. valve block rotating shaft, 3. valve block, 4. sealing ring, 5. rear end valve body.
The specific embodiment
At a kind of blowdown epidemic prevention valve of the present utility model, comprise valve body, valve block (3), valve body sub-headend valve body (1) and rear end valve body (5), use screw-button knot mode to connect in the middle of the two, sealing ring (4) is used in the junction, the rear portion inner chamber enlarging of front end valve body (1), enlarging place forms a ramp platform, at the top of ramp platform one boss is arranged, valve block rotating shaft (2) is arranged on the boss, valve block rotating shaft (2) connects valve block (3), valve block (3) cooperates with the ramp platform of front end valve body (1), out-of-date as effluent stream, under the impact and pressure of sewage, valve block (3) can be opened.When there not being effluent stream out-of-date, valve block (3) becomes airtight mated condition with the ramp platform of front end valve body (1).Valve block (3) material is used plastics.There is water in-out port at two ends.Sewage can pass through, and the most of valve block of giving of foul smell is every living, and can not by or overflow, can thoroughly block foul smell and reflux.Insects such as same mouse, mosquito, screen-like mountain peak dung beetle can not be with bacterium to pass through or propagate.
Claims (2)
1, a kind of blowdown epidemic prevention valve, comprise valve body, valve block, it is characterized in that valve body sub-headend valve body and rear end valve body, the two intermediate active connects, the rear portion inner chamber enlarging of front end valve body, enlarging place forms a ramp platform, at the top of ramp platform one boss is arranged, the valve block rotating shaft is arranged on the boss, the valve block rotating shaft connects valve block, valve block cooperates with the ramp platform of front end valve body, and there is water in-out port at two ends.
2, according to the described a kind of blowdown epidemic prevention valve of claim 1, the water in-out port that it is characterized in that valve body is cylindrical, and the connected mode of front end valve body and rear end valve body is the screw-button knot, and there is sealing ring the junction.
