Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention is described in further detail.
Embodiment 1
Referring to shown in Fig. 1 to Fig. 8, the present invention provides a kind of adjustable flexible cut-off equipment, comprising: shell 1 and rubber sleeve
Cylinder 2, the interior circulation passage 10 being equipped with through its axis of rubber bush 2, shell 1 is sheathed on outside rubber bush 2, and shell 1 and rubber
Rubber sleeve 2 is tightly connected, in the present embodiment can rubber bush 2 top half it is non-deformable, lower half portion is deformable, and shell
Cavity 20 can be filled by being formed between 1 internal partial wall and the outer wall of rubber bush 2, and along the cross-wise direction of shell 1, shell 1 is equipped with
Manhole appendix fills cavity 20 into place Kong Yuke and is connected to, and the manhole appendix in the present embodiment can be single hole or diplopore, when setting single hole
When, two branches are set on transfer pipeline, all the way for into all the way for going out；
When that can fill 20 filling medium of cavity, the deformable segment of rubber bush 2 is to the non-deformable part of rubber bush 2
Side deformation, the deformable segment unilateral side deformation of rubber bush 2, circulation passage 10 become smaller to cut-off, circulation passage off state
Under, the inside of the deformable segment of rubber bush 2 is bonded with the inner tight of non-deformable part, and sealing effect is good.This implementation
Medium in example can be one of air pressure, hydraulic pressure or oil pressure.
Under 1 use state of the present embodiment, the deformable segment of rubber bush 2 is located at the lower half of shell 1, when can fill cavity
20 inflation pressures or water-filling pressure or when oil-filled pressure, deformation occurs for the deformable segment of rubber bush 2, according to the needs of use, can be with
The air pressure or hydraulic pressure or oil pressure, the deformable segment of rubber bush 2 for being filled with certain pressure can progressively close off stream bottom-up
Circulation passage not only can control the on and off of circulation passage, can also carry out flow adjusting, overflow, reverse-filling etc., this reality
It is simple to apply a structure, it is easy to operate, it is vdiverse in function, it is applied widely.
In the present embodiment for adjust circulation passage 10 in flow, can by control rubber bush 2 inflation or water-filling or
Height after oil-filled controls, and intercepts circulation passage 10 from bottom, the top of the circulation passage 10 of position keeps stream
It is logical.
In the present embodiment fill cavity 20 inflation pressure or water-filling pressure or oil-filled pressure after, the deformable segment of rubber bush 2
It is equivalent to overflow weir, when the water flow height of its upstream is more than the height of interception of the rubber bush 2, from the top of the rubber bush 2
Portion overflows to downstream, in addition, deposition or the deposition in shunting well that the rubber bush 2 intercepts duct bottom, prevent bottom
Deposition enters natural water with water flow, pollutes to natural water.And when natural water liquid level is higher, also there is reverse-filling
Function guarantees that the height of rubber bush 2 is higher than the liquid level of natural water, at this time as the water level of upstream is higher than rubber bush 2
Height of interception when, can also from the top of rubber bush 2 overflow flow to the downstream, the case where not influencing flood passage, carry out reverse-filling.
Shell 1 is that cylinder-like structure is sheathed on outside rubber bush 2 in the present embodiment, and circulation passage 10 is axially through rubber
Sleeve 2, rubber bush 2 and shell 1 are coaxially set, and 2 deformable part of rubber bush is divided into the lower half portion of rubber bush,
It is non-deformable at his position.After can fill 20 filling medium of cavity, the lower half portion of rubber bush 2 is deformed, maximum distortion position
Place, 2 lower half portion of rubber bush inside are fitted closely with top half inner wall, circulation passage cut-off.Rubber in the present embodiment
Sleeve 2 is cylinder-like structure, and structure is simple, and rubber bush 2 integrally can be taken out or be mounted in shell 1 out of shell 1, side
Just the installation and removal of rubber bush 2.
Further, in order to realize that rubber bush 2 is deformable positioned at that can fill the part at 20 position of cavity, at other positions
It is non-deformable, there is a following implementations, this place is enumerated and exhaustive, and concrete mode is as follows:
Sleeve-shaped gap is formed between 2 outer wall of 1 inner wall of shell and rubber bush, rubber bush 2 is additionally provided with barrier portion 21, every
Stopper 21 stops rubber bush 2 for deformable segment and non-deformable part, and rubber bush 2 is coaxially set with shell 1, rubber
The end of rubber sleeve 2 is connect with the end of shell 1, and structure is simple, facilitates operation.
Further, barrier portion 21 is sizing liner 21a, and referring to figs. 1 to 5, sizing liner 21a is set to rubber sleeve
The top half cladding sizing liner 21a of inner surface or rubber bush shown in Figure 62 at 2 non-deformable parts of cylinder,
