Abstract
The utility model belongs to an automatic one-way valve, comprising a bell jar, a floating ball and an orifice supporter. The utility model is designed mainly for preventing effluent sewerage overflowing. Each of the top of the bell jar and the bottom of the orifice supporter has an axial valve port; the perisporium process of the junction between the bell jar and the orifice supporter has screw thread; the horizontal cross-section of the inner cavity of the orifice supporter is of elliptical shape or polygon. The utility model can be used for preventing effluent sewerage over-flowing in factories, schools, residential quarters, etc.
Description
The utility model relates to a kind of one way valve, prevents a kind of anti-overflow valve that sewage overflows automatically especially for sewer.
The interior setting without any check device of building sewer now, so cause overflowing of sewage through regular meeting, this not only pollutes, and is difficult to get rid of.
The purpose of this utility model is to solve the problem that sewer overflows, and a kind of novel, easy effluent sewerage automatic anti-overflow valve is provided.
The purpose of this utility model reaches by following technical solution:
The effluent sewerage automatic anti-overflow valve is made up of Bell cover, ball float, bowl holder, respectively opens an axial valve opening at the top of Bell cover and the bottom of bowl holder, and valve opening can be threaded; The Bell cover can be processed with screw thread with bowl junction of holder also can be flanged; The horizontal section of bowl holder inner chamber is ellipse or polygon.
The utility model has the advantages that it does not need power supply, source of the gas or manually-operated, effectively utilize buoyancy of water, ball float is held up the valve opening of blocking Bell cover top, automatically prevented the sewage of sewer to overflow.Under normal circumstances, because bowl holder inner chamber unique design makes ball float can only rest on certain position of bowl holder below, do not influence ducted water toward current downflow.The utility model is than other one way valve, and structure is more apparent simple, easy to manufacture, with low cost, and maintenance, installation are all convenient, can be widely used in places such as factory, hotel, school and residential neighborhoods.
Description of drawings:
Fig. 1 is the sectional view of the utility model vertical cross-section.
Fig. 2 is the utility model A-A sectional drawing.
Below in conjunction with accompanying drawing, the utility model is described in further detail for an embodiment:
Can see that on scheming anti-overflow valve mainly contains three parts and forms: Bell cover 2, ball float 3, bowl holder 4.The bottom of the top of Bell cover 2 and bowl holder 4 respectively has one threaded 5 valve opening 1; Bell cover 2 is processed with screw thread 5 with the junction 6 of bowl holder 4; The surface of internal cavity of bowl holder 4 is a paraboloid, and its horizontal section is oval.Anti-overflow valve can be connected with the sewer pipe by the screw thread of valve opening 1.
Because the diameter of ball float 3 is bigger than the diameter of valve opening 1, when sewer was not blocked, ball float fell because of the gravity of itself is past.Because of the inner chamber of bowl holder 4 is a paraboloid, so ball float 3 just can not fall into the bottom of bowl holder 4, and can only hold in the palm certain position below 4 at bowl, at this moment, ducted water can be successfully from the space of ball float 3 and bowl holder inner chamber toward dirty.In case when the sewage of sewer up overflowed, ball float 3 will rise to Bell along with the rising of water level and cover 2 tops, and the valve opening 1 that will locate is blocked.Following hydraulic pressure is high more, and ball float 3 is sternly more stifled, thereby reaches the purpose that automatic prevention effluent sewerage overflows.After the obstruction of sewer was excluded, anti-overflow valve just recovered normal condition automatically.
The utility model can be made different specification size with different materials, to be applicable to the connection request of different pipelines.Connect if the sewer water pipe is a flange, can change and be threaded to flange and be fastenedly connected.The interior material of ball float is light material or hollow-core construction, and make with rubber or plastics on the surface.
Claims (2)
1, a kind of effluent sewerage automatic anti-overflow valve is characterized in that: it comprises Bell cover, ball float and bowl holder; An axial valve opening is respectively opened with bowl backing end in Bell cover top, and the horizontal section of bowl holder inner chamber is ellipse or polygon.
2, anti-overflow valve according to claim 1 is characterized in that: described Bell cover can be processed with screw thread with the junction of bowl holder, also can be flanged.
