Abstract
The invention relates to a rotary interception flexible flap valve, and belongs to the technical field of control devices on medium pipelines. The rotary interception flexible flap valve comprises a basic frame fixed to the outer wall of the water outlet of a pipeline; a flow channel is formed in the basic frame; the outer edge of basic frame is provided with a flange; a pressure block is fixed outside the flange; a groove is formed between the flange and the pressure block; a flexible diaphragm bar is fixedly connected into the groove; the lower end of the flexible diaphragm bar is fixedly connected with an opening and closing plate; the opening and closing plate has an integral rigid structure; the lower end of the opening and closing plate is a free end; when the opening and closing plate is closed, the opening and closing plate is contacted with the outer end face of the basic frame; the opening and closing plate is in contact connection with one end of a carrier rod; the other end of the carrier rod is electrically connected with an electric driving device. The rotary interception flexible flap valve has an interception (current-regulating) function. Flexible diaphragm cloth is adopted instead of the conventional rigid hinged structure, so that the opening pressure of the valve is very low (namely, low water loss).
Description
Technical field
The invention belongs to the control gear technical field on medium pipeline, be specifically related to a kind of flexible door that dams that rotates.
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 flexible door that dams that rotates 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, can also regulate aperture, be applicable to the water passage system of lower pressure, such as drainage pipe etc. simultaneously.
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, described keying plate contacts with basic frame exterior edge face; Described keying plate is connected with an end in contact of push rod, and the other end of described push rod is electrically connected with Vidacare corp.
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 (the adjusting stream) function of damming, and 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.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, be convenient to be well understood to the present invention, but they do not form restriction to the present invention.
As shown in Figure 1, the present invention includes the basic frame 1 being fixed on pipe water outlet outer wall, in described basic frame 1, be provided with runner 1.1, described basic frame 1 outer is provided with flange 1.2, the outer briquetting 2 that is fixed with of described flange 1.2, between described flange 1.2 and briquetting 2, be provided with groove, in described groove, be fixedly connected with flexible membrane slip 3, described flexible membrane slip 3 is for manufacturing a kind of elastic diaphragm elastic material in membrane valve, described flexible membrane slip 3 lower ends are fixedly connected with and open and close plate 4, described keying plate 4 is integral rigidity structure, described keying plate 4 lower ends are free end, in the time that keying plate 4 is closed, described keying plate 4 contacts with basic frame 1 exterior edge face, the second groove of offering on the first groove that between described flange 1.2 and briquetting 2, set groove is offered by described flange 1.2 exterior edge faces and described briquetting 2 interior edge faces surrounds jointly, described keying plate 4 is connected with an end in contact of push rod 6, and the other end of described push rod 6 is electrically connected with Vidacare corp 7.Between described flexible membrane slip 3 and keying plate 4, be fixedly connected with by screw.
In such scheme, between described keying plate 4 and basic frame 1, be provided with Stamping Steel Ribbon 10.Described keying plate 4 lower ends are provided with groove, in the bonding groove of described Stamping Steel Ribbon 10.Described Stamping Steel Ribbon 10 is hollow-core construction.
As shown in Figure 1, in figure, a direction is water (flow) direction, and this flap valve goes for the water passage system outlet of open type or the jointing by small pipeline access large pipeline, be used for preventing flowing backwards, form backflow pollution, be applicable to the water passage system of lower pressure, such as drainage pipe etc.
Rotary electric drive unit 7 of the present invention is fixed on cement structure, and push rod 6 matches with Vidacare corp, and Vidacare corp 7 can drive push rod 6 to rotate together, thereby controls the aperture that opens and closes plate 4.
The present invention has (the adjusting stream) function of damming, and rotary electric drive unit 7 is housed on top, and Vidacare corp 7 can drive the rotation of push rod 6, thereby realizes the regulation that opens and closes plate 4.Wherein, as shown in Figure 1, push rod 6 rotates counterclockwise and opens and closes plate 4 apertures and increase, and clockwise rotates and opens and closes plate 4 apertures and reduce.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
