Detailed description of the invention
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, it is simple to clear
The present invention is understood on ground, but they do not constitute restriction to the present invention.
As it is shown in figure 1, the present invention includes valve body 1, the runner being arranged in valve body 1 and is arranged on valve body
Valve gap 2 on 1, in described valve body 1, upper end sets near between the valve body 1 and valve gap 2 of water inlet one end
Have groove, groove set between valve body 1 and valve gap 2 by described valve body 1 upper surface offered first recessed
The second groove offered on groove and described valve gap 2 lower surface surrounds jointly, is provided with support in described groove
Axle 3.1, described support shaft 3.1 is fixedly connected with the flexible rubber lobe 3 for sealed valve body 1, institute
Stating and be fixedly connected with positioning block 4 on outside flexible rubber lobe 3, described positioning block 4 is fixed by screws in
On flexible rubber lobe 3, described positioning block 4 is big top and small bottom wedge shape block structure, described tune
Position block 4 is nylon material；Having installing hole 7 on described valve gap 2, described installing hole 7 is built with straight line
Lifting drive 6, described straight line lifting drive 6 is hydraulic cylinder, and the lifting of described straight line drives dress
The outfan putting 6 penetrates in installing hole 7, and the outfan of described straight line lifting drive 6 is fixed with
The positioning wheel 5 matched with positioning block 4.Pass through between described straight line lifting drive 6 and valve gap 2
Gland 9 and bolt 8 are tightly connected.The outfan of described valve gap 2 and straight line lifting drive 6 it
Between be provided with sealing device 10.
In such scheme, as shown in Fig. 1 Fig. 3, described flexible rubber lobe 3 includes being wound in support shaft
Wear-resisting connection band 3.2 outside 3.1 with wear-resisting be connected with 3.2 bottoms connect steel plate frame 3.3, parcel
Rubber slab 3.4 outside wear-resisting connection with 3.2 and steel plate frame 3.3.The described wear-resisting band 3.2 that connects includes
Interconnective canned paragraph 3.21 and linkage section 3.22, described canned paragraph 3.21 top and support shaft 3.1
Fixing connection, described linkage section 3.22 bottom is connected with steel plate frame 3.3, described flexible rubber lobe 3
Center of rotation be positioned on linkage section 3.22.Described wear-resisting band 3.2 materials that connect are nylon cloth.Described
Steel plate frame 3.3 is that upper end is connected with 3.2 Circular plate structures connected with wear-resisting.
In such scheme, as shown in Figure 2, Figure 4 shows, set between described flexible rubber lobe 3 and valve body 1
There is sealing structure 11.Described sealing structure 11 is the part on flexible rubber lobe 3, and described sealing is tied
What structure 11 was the side epirelief that contacts with valve body 1 of flexible rubber lobe 3 for flexible rubber lobe 3 is first convex
Play ring 11.1 and the second protruding ring 11.2, between described first protruding ring 11.1 and the second protruding ring 11.2
It is provided with groove 11.3；The outer of described first protruding ring 11.1 is mutually perpendicular to described valve body 1；Institute
State the protruding thickness thickness more than the first protruding ring 11.1 of the second protruding ring 11.2, described second convex
Play ring 11.2 to be in tilted layout to the direction along flexible rubber lobe 3 outer, described second protruding ring 11.2
The flexible rubber lobe 3 of rear end be provided with the bending activity space 11.4 for the second protruding ring 11.2.
When flexible rubber lobe 3 contacts in valve body 1, the second protruding ring 11.2 can first contact with valve body 1, real
Now sealing, the air in groove 11.3 is extruded, and now can realize ultralow pressure and seal.Flexible rubber lobe
Sealing structure 11 between 3 and valve body 1, it is possible to achieve during low pressure (or without pressure), only by flap
The i.e. deadweight of flexible rubber lobe 3 just can close sealing, and need not from gravity of simultaneously sealing is very big,
The unlatching water that can allow valve damages the lowest；When having high pressure after valve, the sealing structure of flexible rubber lobe is at bullet
Property deformation range in, meanwhile, for second protruding ring 11.2 bending activity space 11.4, it is ensured that
Flexible rubber lobe under maximum working pressure is can reach indeformable during high pressure sealing.
The positioning block 4 being fixed with wedge structure on flexible rubber lobe 3 of the present invention matches with positioning wheel 5,
By straight line lifting drive 6 outfan knee-action, drive positioning wheel 5 knee-actions, and then
Coordinate the positioning block 4 of wedge structure, control the size of flexible rubber lobe 3 aperture, thus automatically control water
The size of stream.
The upper end of flexible rubber lobe 3 of the present invention is fixed in the groove of valve gap 2 and valve body 1, it is impossible to from
By rotating, the keying of valve is realized by the flexible bending of flexible rubber lobe 3, and bending power is very
Little, almost it is negligible.Nylon cloth can realize the flexible bending of flexible rubber lobe, and rolls over
Curved power is the least, and warping resistance fatigability is effective.3.3 pressure-bearings of steel plate frame close valve action, make in back pressure
Under with, flexible rubber lobe 3 will not deform.The keying of valve of the present invention is rotated through flexible rubber lobe 3
Realizing, flexible rubber lobe 3 liner nylon cloth strengthens toughness, counter-bending fatigue, middle part lined steel
Framework 3.3, plays pressure-bearing and closes valve action, the center of rotation of flexible rubber lobe 3 and steel plate frame center of gravity position
It is equipped with certain bias, it is ensured that flexible rubber lobe 3 can lean on the effect of deadweight to close in the case of without pressure.
The content that this specification is not described in detail belongs to existing skill known to professional and technical personnel in the field
