Abstract
The utility model relates to a kind of back-water-proof sewer valve, comprise U-tube (1) and sewer manifold (7), U-tube (1) is communicated with in one with sewer manifold (7), sewer manifold (7) is provided with lid (2), lid (2) is fastening by screw thread (3) and sewer manifold (7), it is characterized in that: sewer manifold (7) lower end is provided with loudspeaker valve port (5), buoyancy valve ball (6) is provided with in loudspeaker valve port (5), buoyancy valve ball (6) is provided with connection cord (4), and the other end of connection cord (4) is fixed on lid (2).The utility model plays the effect preventing from turning one's coat, and ensure that sewage can not instead to ground.
Description
Technical field
The utility model belongs to architectural hardware technical field, particularly relates to a kind of back-water-proof sewer valve.
Background technology
Existing sewer multidigit U-tube structure, like this can anti-non-return waste gas, but but can not play the effect preventing from turning one's coat.Live and often run into the situation of sewer blockage, for low layer resident family, especially bottom resident family, the sewer that will cause is turned one's coat, and stinks to high heaven, and suffers untold misery.
Summary of the invention
In order to solve the above problem, the utility model provides a kind of back-water-proof sewer valve, and it is the improvement carried out on the basis of the anti-return pipe of original sewer.The utility model is achieved in the following ways: a kind of back-water-proof sewer valve, comprise U-tube and sewer manifold, U-tube is communicated with in one with sewer manifold, sewer manifold is provided with lid, cover by screw thread and sewer manifold fastening, it is characterized in that: sewer manifold lower end is provided with loudspeaker valve port, is provided with buoyancy valve ball in loudspeaker valve port, buoyancy valve ball is provided with connection cord, and the other end of connection cord is fixed on and covers.
The utility model plays the effect preventing from turning one's coat, and ensure that sewage can not instead to ground.

Detailed description of the invention
With reference to accompanying drawing, a kind of back-water-proof sewer valve, comprise U-tube 1 and sewer manifold 7, U-tube 1 is communicated with sewer manifold 7 in one, and sewer manifold 7 is provided with lid 2, and lid 2 is fastening by screw thread 3 and sewer manifold 7, it is characterized in that: sewer manifold 7 lower end is provided with loudspeaker valve port 5, be provided with buoyancy valve ball 6 in loudspeaker valve port 5, buoyancy valve ball 6 is provided with connection cord 4, and the other end of connection cord 4 is fixed on lid 2.The external diameter of buoyancy valve ball 6 is slightly larger than the bore of sewer manifold 7; Buoyancy valve ball 6, for being hard material hollow ball, is provided with rubber crust outside buoyancy valve ball 6 spheroid.Rubber crust better can play sealing function; And use hard material that pressure can be avoided to cross ambassador's floating valve ball 6 to be out of shape, ineffective.
Buoyancy valve ball 6 in the utility model floats by buoyancy when turning one's coat, and blocks sewer manifold 7, plays the effect preventing from turning one's coat.Ensure that sewage can not instead to ground.
