Description
Technical field
The invention belongs to the control gear technical field on medium pipeline, be specifically related to a kind of lifting flexible door that dams.
Background technique
Existing flap valve structure is rigid hinge formula structure, without flexible structure.Due to the reason of metallic material, self gravitation is larger, in the water passage system of lower pressure (or with no pressure), flap valve can not be washed open by water, and then play and open and the effect of non-return, meanwhile, existing flap valve does not have (adjusting stream) function, and therefore designing a kind of check device according to the water passage system of lower pressure (or with no pressure) becomes technical barrier.
Summary of the invention
Object of the present invention is exactly the defect for prior art, and a kind of lifting flexible door that dams is provided.Be applicable to the water passage system outlet of open type or the jointing by small pipeline access large pipeline, flow backwards for preventing, form backflow pollution, be applicable to the water passage system of lower pressure, such as drainage pipe etc.
The technical solution used in the present invention is: comprise the basic frame being fixed on pipe water outlet outer wall, in described basic frame, be provided with runner, described basic frame outer is provided with flange, described flange is fixed with briquetting outward, between described flange and briquetting, be provided with groove, in described groove, be fixedly connected with flexible membrane slip, described flexible membrane slip lower end is fixedly connected with keying plate, described keying plate is integral rigidity structure, described keying plate lower end is free end, in the time that keying plate is closed, end contact outside described keying plate and basic frame, described keying plate is fixedly connected with positioning piece on outside, on described flange, be fixed with the mounting plate perpendicular with basic frame, on described mounting plate, have mounting hole, be provided with straight line lift driving mechanism in described mounting hole, the output terminal of described straight line lift driving mechanism is fixed with the positioning wheel matching with the piece of transposing.
Further preferred structure, described positioning piece is nylon material.
Further preferred structure, described positioning piece is big top and small bottom wedge shape block structure.
Further preferred structure, is bolted to connection between described straight line lift driving mechanism and mounting plate.
Further preferred structure, described positioning piece is fixed by screws in and opens and closes on plate.
Further preferred structure, is fixedly connected with by screw between described flexible membrane slip and keying plate.
Further preferred structure, is provided with Stamping Steel Ribbon between described keying plate and basic frame.
Further preferred structure, described keying plate lower end is provided with groove, in the bonding groove of described Stamping Steel Ribbon.
Further preferred structure, described Stamping Steel Ribbon is hollow-core construction.
The present invention has adopted flexible membrane cloth to replace traditional rigidity hinge structure, the cracking pressure very low (i.e. low damage by water) that has realized valve; Having adopted in addition special gasket structure, is hollow-core construction in the middle of this Stamping Steel Ribbon, and this Stamping Steel Ribbon seal pressure is very low, and low pressure is easy to realize sealing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
