Between be provided with groove, groove set between valve body 1 and valve gap 2 is offered by described valve body 1 upper surface
The second groove offered on first groove and described valve gap 2 lower surface surrounds jointly, sets in described groove
There is support shaft 3.1, described support shaft 3.1 is fixedly connected with the flexible rubber lobe for sealed valve body 1
3；On described valve body 1, both sides have two coaxial installing holes 12, set in said two installing hole 12
Having rotating shaft 5, described rotating shaft 5 connects gag lever post 4 one end, described gag lever post 4 other end withstands described
Flexible rubber lobe 3, described rotating shaft 5 electrically connects with Vidacare corp 10.Described gag lever post 4 connects
The both sides of one end of rotating shaft 5 are provided with jump ring 7, and described jump ring 7 is sheathed in rotating shaft 5.Described gag lever post
It is connected by key 8 between 4 and rotating shaft 5.Side on valve body 1 is stretched out in one end of described rotating shaft 5
Electrically connecting with Vidacare corp 10 after installing hole 12, the other end of described rotating shaft 5 is placed in valve body 1
In the installing hole 12 of upper opposite side, installing hole 12 is externally provided with valve gap 9, and described valve gap 9 passes through screw
11 are tightly connected with valve body 1.Described Vidacare corp 10 is fixedly connected on the side outside valve body 1.
Being provided with copper sheathing 6 in described installing hole 12, described rotating shaft 5 two ends are inserted in copper sheathing 6 respectively.
In such scheme, shown in Fig. 3, Fig. 4, described flexible rubber lobe 3 includes being wound in
Support axle 3.1 outside wear-resisting connection band 3.2 with wear-resisting is connected with 3.2 bottoms connections steel plate frame 3.3,
It is wrapped in the rubber slab 3.4 outside wear-resisting connection with 3.2 and steel plate frame 3.3.Described wear-resisting connection band 3.2
Including interconnective canned paragraph 3.21 and linkage section 3.22, described canned paragraph 3.21 top and support shaft
3.1 fixing connections, described linkage section 3.22 bottom is connected with steel plate frame 3.2, described flexible rubber lobe
The center of rotation of 3 is 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 4, Figure 5, set between described flexible rubber lobe 3 and valve body 1
There is sealing structure 13.Described sealing structure 13 is the part on flexible rubber lobe 3, and described sealing is tied
What structure 13 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 13.1 and the second protruding ring 13.2, between described first protruding ring 13.1 and the second protruding ring 13.2
It is provided with groove 13.3；The outer of described first protruding ring 13.1 is mutually perpendicular to described valve body 1；Institute
State the protruding thickness thickness more than the first protruding ring 13.1 of the second protruding ring 13.2, described second convex
Play ring 13.2 to be in tilted layout to the direction along flexible rubber lobe 3 outer, described second protruding ring 13.2
The flexible rubber lobe 3 of rear end be provided with the bending activity space 13.4 for the second protruding ring 13.2.
When flexible rubber lobe 3 contacts in valve body 1, the second protruding ring 13.2 can first contact with valve body 1, real
Now sealing, the air in groove 13.3 is extruded, and now can realize ultralow pressure and seal.Flexible rubber lobe
Sealing structure 13 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 13.2 bending activity space 13.4, it is ensured that
Flexible rubber lobe under maximum working pressure is can reach indeformable during high pressure sealing.
The present invention is in the side of valve body equipped with Vidacare corp 10, and Vidacare corp 10 drives and turns
The rotation of axle 5, the rotation rotarily driving gag lever post 4 of rotating shaft 5, and then control flexible rubber lobe 3,
Thus realize the aperture regulation of flexible rubber lobe 3.
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
