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 is and in particular to a kind of roller shutter type flexible door.
Background technology
Existing flap valve door-plate is generally formed through the shaft by between metal material and door-plate and door body, such flap valve warp
Often because door-plate own wt is overweight and shaft connection place abrasion and the reason such as get rusty, cause opening of device power and close shock behind the door
Power is excessive and damage inactivation concurrently there are water undermine impact force excessive the shortcomings of, and only one door-plate sealing at flap valve runner mouth,
The size of runner mouth according to practical situation, can not be adjusted, be unfavorable for removing impurity.
Content of the invention
The purpose of the present invention is aiming at the defect of prior art, provides a kind of roller shutter type flexible door.
The technical solution used in the present invention is：Including the door body having runner, described door body outer wall is fixed with cylinder
Body, the longitudinal center section of described body is the trapezium structure of the short bottom in top length, and described body outer face forms inclination
Runner mouth, is provided with the multiple flexible rubber plate sealings being parallel to each other from top to bottom at described runner mouth.
Further preferred structure, is provided with propping up of the level being fixed on tube wall between the plurality of flexible rubber plate
Support beam, described flexible rubber top of the plate portion sequentially passes through rustless steel press strip, flexible rubber plate and PVC liner from outside to inside by bolt
After be fixed in body top or support beam.
Further preferred structure, between described flexible rubber plate bottom and support beam below or its bottom respectively
It is provided with sealing structure.
Further preferred structure, described sealing structure sequentially passes through rustless steel press strip and sealing from outside to inside by bolt
It is fixed on after structure in support beam or its bottom.
Further preferred structure, described sealing structure bend in the same direction with respect to interlude for the left and right sides after shape
The groove structure becoming, the left side of described sealing structure is contacted with flexible rubber plate, and the right side of described sealing structure is fixed on support
On beam or body.
Further preferred structure, described sealing structure is rubber blanket.
Further preferred structure, described flexible rubber plate is fixed with several rustless steel reinforcing plates.
Further preferred structure, described rustless steel reinforcing plate is fixed with handle.
Further preferred structure, described body top outer is provided with hanger.
Quality of the present invention is light compared with cast iron or rustless steel flap valve door-plate, and therefore its rotary inertia is little, so that closing anterior angle
Speed and close impact force and reduce, can bear attack and the wave action of the high water head after closing and pump discharge, and if necessary
Stainless steel handle manual unlocking door-plate can be passed through, wash out impurity；PVC liner makes the flexible connection that door-plate and body are integrated make out
Qi Li is less, opens rapider, and hinge-less or hinge pin abrasion or requirement lubricate；The opening of door-plate is big according to the bore of runner mouth
Little be designed as one or more rustless steel support beams, runner mouth is divided into single or multiple openings, sewage discharge application in, many
The roller shutter type flexible door of individual opening is easier to safeguard, opening is little, and door-plate is easier to open and removes impurity；Sealing structure makes pipe
Body becomes elastic packing with rubber door plate shape, reveals little and no metal bump noise.The present invention be applicable not only to water with pressure to
Drainage system, but also be preferably used for from the sewage drainage system of density current.

Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is easy to be well understood to this
Bright, but they do not constitute restriction to the present invention.
As shown in Figure 1 and Figure 2, the present invention includes the door body 1 having runner, and described door body 1 outer wall is fixed with cylindrical tube
Body 2, the longitudinal center section of described body 2 is the trapezium structure of the short bottom in top length, and described body 2 outer face forms inclination
Runner mouth, is provided with the multiple flexible rubber plates 3 being parallel to each other from top to bottom and seals at described runner mouth, in conjunction with shown in Fig. 2, this reality
Apply and be provided with two flexible rubber plates 3 being parallel to each other from top to bottom at runner mouth described in example and seal, on described flexible rubber plate 3
Several rustless steel reinforcing plates 4 are fixed with by bolt 10, described rustless steel reinforcing plate 4 is fixed with handle 5, described body 2
Top outer is provided with hanger 6.The present invention is mountable to pipe flange and wall entirely through the fixing hole 11 being arranged in door body 1
On.
As shown in Figure 2 and Figure 3, it is provided with propping up of the level being fixed on body 2 outer wall between described two flexible rubber plates 3
Support beam 9, described flexible rubber plate 3 top sequentially passes through rustless steel press strip 8, flexible rubber plate 3 and from outside to inside by bolt 10
It is fixed on after PVC liner 7 in body 2 top or support beam 9.
As shown in Figure 2, Figure 4 shows, between described flexible rubber plate 3 bottom and support beam below 9 or body 2 bottom respectively
It is provided with sealing structure 12, described sealing structure 12 sequentially passes through rustless steel press strip 8 and sealing structure from outside to inside by bolt 10
It is fixed on after 12 in support beam 9 or body 2 bottom, described sealing structure 12 is rubber blanket.As shown in figure 5, described sealing structure
12 bend in the same direction with respect to interlude 12.2 for the left and right sides 12.1,12.3 after formed groove structure 12.4, described
The left side 12.1 of sealing structure 12 is contacted with flexible rubber plate 3, the right side 12.3 of described sealing structure 12 be fixed on support beam 9 or
On body 2.
Door-plate of the present invention is flexible rubber plate, and has certain angle of inclination it is ensured that door-plate can be in the effect of deadweight
Under voluntarily close formed sealing.During normal operation, door-plate is backed down and outflows by means of the impulse force of itself by current；During non-water flow, door body
Fall in the presence of deadweight；Hereafter, door-plate, again under reverse water pressure effect, is pressed in sealing structure, stops water body from flowing backwards.
The content that this specification is not described in detail belongs to prior art known to professional and technical personnel in the field.
