Abstract
The invention relates to a gate with the non-return function, and belongs to the technical field of water supply and drainage equipment. The upper end of a wedge disc is connected with a lifting drive device, an opening is formed in the lower end of the wedge disc, and one side of the opening is connected with a one-way non-return flap valve for sealing the opening. When the gate needs to be quickly opened for flood discharge, the flap valve is automatically opened to quickly discharge flood, and therefore flood disasters caused by human factors are avoided.
Description
Technical field
The invention belongs to plumbing equipment technical field, be specifically related to a kind of gate with check function.
Background technology
The gate of nothing with check function in existing gate, but a lot of occasions, the position that gate is installed only needs one-way water stop, and the flow direction that does not need sealing often needs long-term unlatching, in order to avoid occur opening not in time and pouring in down a chimney phenomenon, therefore need to design the utilization demand of a kind of gate with check function to this special occasions of draining industry.
Summary of the invention
Object of the present invention is exactly the defect for prior art, and a kind of gate with check function is provided.Reduce well traffic flow in current forward proper flow, oppositely can realize break-in facility at current.
The technical solution used in the present invention is: comprise the flashboard being arranged in pipe duct, described flashboard upper end connects lifting drive, and described flashboard lower end is provided with opening, and described opening one side is connected with the one-way non-return flap valve for sealed open.
Further preferred structure, described one-way non-return flap valve comprises the flexible membrane slip on the flashboard that is fixed on opening top, 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 the flashboard of opening below.
Further preferred structure, is fixed with briquetting on the flashboard of described opening top, between described flashboard and briquetting, is provided with groove, and described flexible membrane slip upper end is fixed in groove.
Further preferred structure, is provided with weather strip between described keying plate and flashboard.
Further preferred structure, described keying plate lower end is provided with groove, in the bonding groove of described weather strip.
Further preferred structure, described weather strip is hollow-core construction.
Gate of the present invention for a long time in the time cutting off the water supply duty, lock under gate, flap valve is closed, now gate blocks for a long time, pour in down a chimney if meet emergency (as waterlogging waterflooding) water, while needing quick starting gate flood discharge, flap valve is opened quick flood discharge automatically, avoid the big flood causing because of human factor, meanwhile, therefore gate has the way flow general character, has avoided some mistake open operation, cause having released of should not releasing, and this is not released when releasing.
Brief description of the drawings
Fig. 1 is structural front view of the present invention;
Fig. 2 is structure side view of the present invention;
Fig. 3 is one-way non-return flap valve structural representation.
Detailed description of the invention
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 and Figure 2, the present invention includes the flashboard 1 being arranged in pipe duct 9, described flashboard 1 upper end connects lifting drive 2, and described flashboard 1 lower end is provided with opening 4, and described opening 4 one sides are connected with the one-way non-return flap valve 5 for sealed open 4.
One-way non-return flap valve 5 in the present invention can be existing rigidity flap valve.Also can be flexible door, as shown in Figure 3, described one-way non-return flap valve 5 comprises the flexible membrane slip 7 on the flashboard 1 that is fixed on opening 4 tops, described flexible membrane slip 7 is for manufacturing a kind of elastic diaphragm elastomeric material in diaphragm valve, described flexible membrane slip 7 lower ends are fixedly connected with and open and close plate 8, and described keying plate 8 is integral rigidity structure, and described keying plate 8 lower ends are free end, in the time that keying plate 8 is closed, described keying plate 8 contacts with the flashboard 1 of opening 4 belows.On the flashboard 1 of described opening 4 tops, be fixed with briquetting 6, between described flashboard 1 and briquetting 6, be provided with groove, described flexible membrane slip 7 upper ends are fixed in groove.
In such scheme, between described keying plate 8 and flashboard 1, be provided with weather strip 3.Described keying plate 8 lower ends are provided with groove, in the bonding groove of described weather strip 3.Described weather strip 3 is hollow-core construction.
The content that this manual is not described in detail belongs to the known prior art of professional and technical personnel in the field.
