Abstract
The utility model provides a flap valve with a side direction type full automatic non-return device, and relates to valves used in river pipe networks, water outlet of pumps, water conservancy systems, municipal sewage, urban flood control and waterlogged land drain, sewage treatment works and tap water works. The flap valve with the side direction type full automatic non-return device comprises a valve frame and a valve cover. Two side hinged supports are fixedly connected with one end of the valve frame. Each side hinged support is respectively connected with the valve cover through a hinge. One end, far away from the valve cover, of each hinge is respectively connected with a limiting mechanism. One end, facing the valve cover, of the valve frame is connected with a rubber sealing element. The flap valve with the side direction type full automatic non-return device has the advantages that the flap valve with the side direction type full automatic non-return device is large in open angle and open area, and smaller in head loss compared with a traditional flap valve when being opened so as to work, wherein a hinge support of the traditional flap valve is arranged above, is free from external power, capable of automatically closing by self-weight when being closed, and is provided with limiting devices so as to prevent the flap valve with the side direction type full automatic non-return device from being incapable of automatically returning when being opened to the maximum degree.
Description
Technical field
The valve that the utility model relates to the river pipe network, pumps the mouth of a river, water conservancy system, municipal wastewater, urban flood defence water drainage, sewage treatment works, waterworks etc. use.
Background technique
Flap valve is mounted in a kind of one-way valve of rivers limit drainpipe outlet, and the hydraulic pressure in flap valve is then opened greater than the flap valve outside pressure; When the rivers tidal level is higher than effluent pipe mouth, and pressure is during greater than overpressure, and the door closure autoshutdown of flap valve is in case rivers tidewater pours in down a chimney in the intake-discharge pipe road.Existing flap valve is because structure unreasonable so that opening angle is little, resistance of medium is large, energy loss is many, at the bottom of the unit efficiency, large-scale flap valve particularly, must be equipped with hydraulic hoist can use, and also has impact force and problem of water hammer.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of flap valve with side full-automatic non-return apparatus to be provided.
The purpose of this utility model is achieved in that the flap valve with side full-automatic non-return apparatus, comprise doorframe and door closure, end at doorframe is fixedly connected with two side free bearings, each side free bearing is connected with described door closure by hinge respectively, each hinge connects respectively position-limit mechanism away from an end of door closure, and described doorframe connects rubber packing spare towards an end of door closure.
The oblique setting of one end of doorframe of the present utility model, described two side free bearings are connected to an end of the oblique setting of doorframe.
Doorframe of the present utility model is cylindrical shape, and described door closure is circular.
Doorframe of the present utility model is square, and described door closure is square.
The utility model has following characteristics by above design: when 1. flap valve was opened work, opening angle was large, and area of passage is large; Loss of head is little with respect to traditional free bearing flap valve up.When 2. flap valve is closed, need not outer power, by the deadweight autoshutdown.3. flap valve had limit stoper when opening maximum position, prevented that flap valve can not self-return.
