Abstract
The utility model discloses an air supplementing and venting valve which mainly comprises a valve body, a valve cover, a main path, a port for communicating air in and out of the valve, a water/air flow path which also serves as a floating ball support, a sealing member and a floating ball, wherein the top of the valve cover is provided with an auxiliary air path; the port for communicating air in and out of the valve is mutually communicated with air outside the auxiliary air path or the valve body; the water/air flow path which also serves as a floating ball support not only provides support for the vertical motion of the floating ball but also performs the functions of a water/air flow path; the valve cover and the valve body are connected by a screw thread or a flange; the sealing member is arranged between the valve body and the valve cover; the water/air flow path which also serves as a floating ball support is arranged at the inner side of the valve body and is combined with the valve body into a whole; and the main path is connected with water equipment. The air supplementing and venting valve can be matched with various closet pans and can be widely applied to occasions needing water backflow prevention in water supply and drainage, such as houses, hotels, office buildings, apartments and other buildings.
Description
Technical field
A kind of tonifying Qi outlet valve of the utility model relate to the building water supply and drainage pipe-line equipment relate in particular to a kind of structure of various w.c.pans coupling succinctly, low price, a kind of tonifying Qi outlet valve of service-strong.
Background technique
Existing w.c.pan flushing system is when utilizing city tap-water directly to wash; Between w.c.pan and tap water pipe network; Generally be to adopt antifouling isolating valve to prevent the sewage refluence phenomenon that causes because of the pipe network negative pressure; Emit water and hydraulic pressure to utilize problems such as insufficient easily because traditional antifouling isolating valve exists, thereby influenced tap water and fling the w.c.pan product and come into the market, also be unfavorable for the development in an all-round way of building energy conservation cause.
Summary of the invention
The purpose of the utility model just is: a kind of both low prices are provided, and structure is succinct, use is reliable, the little a kind of tonifying Qi outlet valve of loss of head.
The utility model is realized through following scheme: mainly comprise valve body, valve gap, main passage, valve inner air and outer air connecting port, current and air-flow path hold concurrently ball float support, seal and ball float; Be provided with the air subaisle at the top of valve gap, the outside air of valve inner air and outer air connecting port and air subaisle or valve body is interconnected.Current and the air-flow path ball float of holding concurrently supports and not to be merely the ball float vertical motion and to provide support, and the channeling of current or air stream is also played in the ball float support of holding concurrently of current and air-flow path simultaneously.During normal water supply; Current support and get in the valve through main passage and current and the air-flow path ball float of holding concurrently; Ball float is done ascending motion under the floating function of current; When ball float rose to the seal place, ball float was sealed valve inner air and outer air connecting port immediately under hydraulic pressure and floating function, had avoided the current waste that leaks; When the unexpected accident of pipe network cut off the water or the people when cutting off the water; Ball float moves downward ball float support place of holding concurrently of current and air-flow path and falls surely; The valve outer air is held concurrently through valve inner air and outer air connecting port, current and air-flow path at this moment, and ball float supports and the main passage gets into watering equipment; Even negative pressure appearance has taken place pipe network, the sewage in the watering equipment is stopped and has avoided sewage to flow backwards to take place to the accident of tap water pipe network also because of the timely entering of atmosphere.Valve gap adopts screw thread or flange to be connected with valve body; Seal is arranged at the sealed mouth place between valve body and the valve gap; Current and air-flow path hold concurrently ball float support be arranged at valve body inboard and with valve body be an integral body, the main passage is adopted screw thread or flange to connect and is connected with watering equipment.
A kind of tonifying Qi outlet valve of the utility model not only can use with various w.c.pans coupling, also adaptable across place that dwelling house, hotel, office building, apartment and other building water supply and drainages need prevent aqueous reflux.
