Abstract
The invention relates to a roller shutter type flexible flap valve, and belongs to the technical field of water supply and drainage equipment. The roller shutter type flexible flap valve comprises a valve body with a flow channel. A cylindrical pipe is fixed to the outer wall of the valve body. The center section in the longitudinal direction of the pipe is of a trapezoidal structure with the top end shorter than the bottom end. An inclined flow channel opening is formed in the outer end surface of the pipe and provided with a plurality of parallel flexible rubber plates from top to bottom for sealing. The roller shutter type flexible flap valve is easier to maintain, the opening is small, a valve plate can be opened more easily, and impurities can be removed more easily.
Description
Technical field
The invention belongs to plumbing equipment technical field, be specifically related to a kind of rolling curtain type flexible door.
Background technique
Existing flap valve door-plate is generally by being formed through the shaft between metallic material and door-plate and door body, such flap valve is often due to reasons such as door-plate own wt are overweight and wearing and tearing in shaft connection place and gets rusty, cause opening of device power and close the excessive and damage inactivation of impact force behind the door simultaneously, there is the shortcomings such as damage by water and impact force be excessive, and flap valve runner mouth place is a door-plate sealing only, can not, according to actual conditions, regulate the size of runner mouth, be unfavorable for removing impurity.
Summary of the invention
Object of the present invention is exactly the defect for prior art, and a kind of rolling curtain type flexible door is provided.
The technical solution used in the present invention is: comprise the door body that has runner, on the external wall of described door, be fixed with cylindrical tube, the longitudinal center cross section of described body is the long trapezium structure in short bottom, top, described body exterior edge face forms the runner mouth of inclination, and described runner mouth place is provided with the multiple flexible rubber plate sealings that are parallel to each other from top to bottom.
Further preferred structure, between described multiple flexible rubber plate, be provided with the support beam that is fixed on the level on tube wall, described flexible rubber plate top is fixed on body top or support beam through after stainless steel press strip, flexible rubber plate and PVC liner from outside to inside successively by bolt.
Further preferred structure, is respectively equipped with sealing configuration between the support beam of described flexible rubber plate bottom and its below or body bottom.
Further preferred structure, described sealing configuration is fixed on support beam or body bottom after passing successively from outside to inside stainless steel press strip and sealing configuration by bolt.
Further preferred structure, described sealing configuration is the left and right sides bends rear formation in the same direction groove structure with respect to intermediate section, and the left side of described sealing configuration contacts with flexible rubber plate, and the right side of described sealing configuration is fixed on support beam or body.
Further preferred structure, described sealing configuration is rubber pad.
Further preferred structure, is fixed with several stainless steel stiffening plates on described flexible rubber plate.
Further preferred structure, is fixed with handle on described stainless steel stiffening plate.
Further preferred structure, described body top outer is provided with hanger.
Quality of the present invention wants light compared with cast iron or stainless steel flap valve door-plate, therefore its rotary inertia is little, reduce thereby make to close front angular velocity and close an impact force, can bear attack and the wave action of high head after closing and pump discharge, and can pass through if desired stainless steel handle manual unlocking door-plate, wash out impurity; Flexibly connecting that PVC liner makes that door-plate and body be integrated makes opening force less, open rapider, hinge-less or the wearing and tearing of twisting pin or require lubricated; The opening of door-plate is designed to one or more stainless steel support beams according to the caliber size of runner mouth, runner mouth is divided into single or multiple openings, and in effluent discharge application, the rolling curtain type flexible door of multiple openings is more easily safeguarded, opening is little, and door-plate is more easily opened and removed impurity; Sealing configuration makes body and rubber door-plate form elastic packing, reveals little and without the noise of metal bump.The present invention is not only applicable to water supply and drain water system with pressure, but also better for the sewage drainage system from density current.

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 Fig. 1, shown in Fig. 2, the present invention includes the door body 1 that has runner, on described door body 1 outer wall, be fixed with cylindrical tube 2, the longitudinal center cross section of described body 2 is the long trapezium structure in short bottom, top, described body 2 exterior edge faces form the runner mouth of inclination, described runner mouth place is provided with the multiple flexible rubber plates 3 that are parallel to each other from top to bottom and seals, shown in Fig. 2, the mouth of runner described in the present embodiment place is provided with two flexible rubber plates 3 that are parallel to each other from top to bottom and seals, on described flexible rubber plate 3, be fixed with several stainless steel stiffening plates 4 by bolt 10, on described stainless steel stiffening plate 4, be fixed with handle 5, described body 2 top outer are provided with hanger 6.Entirety of the present invention can be installed on piping flange and wall by the fixed hole 11 being arranged on a body 1.
As shown in Figure 2 and Figure 3, between described two flexible rubber plates 3, be provided with the support beam 9 that is fixed on the level on body 2 outer walls, described flexible rubber plate 3 tops are fixed on body 2 tops or support beam 9 through after stainless steel press strip 8, flexible rubber plate 3 and PVC liner 7 from outside to inside successively by bolt 10.
As shown in Figure 2, Figure 4 shows, between the support beam 9 of described flexible rubber plate 3 bottoms and its below or body 2 bottoms, be respectively equipped with sealing configuration 12, described sealing configuration 12 is by bolt 10 from outside to inside successively through being fixed on support beam 9 or body 2 bottoms after stainless steel press strip 8 and sealing configuration 12, and described sealing configuration 12 is rubber pad.As shown in Figure 5, described sealing configuration 12 is the groove structure 12.4 forming after the left and right sides 12.1,12.3 bends in the same direction with respect to intermediate section 12.2, the left side 12.1 of described sealing configuration 12 contacts with flexible rubber plate 3, and the right side 12.3 of described sealing configuration 12 is fixed on support beam 9 or body 2.
Door-plate of the present invention is flexible rubber plate, and have certain angle of inclination, has guaranteed that door-plate can cut out voluntarily under the effect of deadweight to form sealing.When normal operation, current borrow the impulse force of self door-plate is backed down and outflow; When non-water flow, door body falls under the effect of deadweight; After this, door-plate under reverse water pressure effect, is pressed in sealing configuration again, stops water body to flow backwards.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
