Compared with the prior art, the electric rubber liner membrane valve has the advantages of completely eradicating running, spilling, dropping and leaking of a normal valve, and the like.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of electronic rubber lined diaphragm.
Background technique
Electronic rubber lined diaphragm be with barrier film as open-shut device, moved up and down along axis by Electric actuator band ovable valve stem, driver part and medium are in isolation.Major function is the medium that switches on or off in the pipeline, the start-stop device that control media flows.
Because working condition need to be to the valve higher control requirement that claims; the demand of working condition has been satisfied in the configuration of Electric actuator, it can carry out field control, can for trasher's alternative on the spot control, can telecontrol, the specific demand such as can interlock, can condition control, can promptly protect.
Because barrier film is the vital part of keying and the sealing of membrane valve, the quality of its quality directly has influence on sealability and the working life of valve, therefore, the structure of diaphragm of rubber and material will and play vital effect working life to the sealability of membrane valve.
At present, it is easy to wear, aging that many membrane valves exist barrier film, and many drawbacks such as valve run, drip, leak happen occasionally.
The model utility content
The purpose of this utility model is exactly to provide a kind of electronic rubber lined diaphragm for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of electronic rubber lined diaphragm is characterized in that, comprises barrier film, flap, valve rod, Electric actuator, valve gap and valve body; Form the space that holds flap, valve rod after shown valve body is connected with valve gap, described barrier film is located at the joint of valve body and valve gap, and described valve rod lower end is connected with barrier film by flap, and described valve rod upper end is connected with Electric actuator.
Described flap is provided with pin, and described flap is connected with barrier film by pin.
Described valve rod is provided with Stem Mut, and this Stem Mut and valve gap joint are provided with Upper gasket and lower levelling plate.
Described valve gap is provided with the second adpting flange, and is connected with it by screw.
Described Electric actuator is connected with the second adpting flange by the first flange.
Described the second flange is connected with the first flange by the first fastener assembly, and described the first fastener assembly comprises bolt, the first packing ring and the first nut.
Described the first flange is connected with Electric actuator by the second fastener assembly, and described the second fastener assembly comprises the first double-screw bolt, the second nut and the second packing ring.
Described the first flange and Electric actuator joint are provided with flange gasket.
Described valve body is connected with valve gap by the 3rd fastener assembly, and described the 3rd fastener assembly comprises the second double-screw bolt and the 3rd nut.
Compared with prior art, the utlity model has following advantage:
1, operation control is functional strong, satisfies the user under various working conditions, to the operation of membrane valve.
2, valve body becomes stiffness breakage and fatigue performance with diaphragm design, make Korrosionsmedium and all driver parts in the runner be in the fully state of isolation, thereby thoroughly stopped the phenomenons such as " run, drip, leak " of common valve, therefore has special good decay resistance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
Such as Fig. 1, a kind of electronic rubber lined diaphragm comprises barrier film 1, flap 2, valve rod 4, Electric actuator 13, valve gap 19 and valve body 22; After being connected with valve gap 19, shown valve body 22 forms the space that holds flap 2, valve rod 4, described barrier film 1 is located at the joint of valve body 22 and valve gap 19, described valve rod 4 lower ends are connected with barrier film 1 by flap 2, and described valve rod 4 upper ends are connected with Electric actuator 13.
Described flap 2 is provided with pin 3, and described flap 2 is connected with barrier film 1 by pin 3.
Described valve rod 4 is provided with Stem Mut 7, and this Stem Mut 7 is provided with Upper gasket 11 and lower levelling plate 6 with the valve gap joint.Described valve gap 19 is provided with the second adpting flange 18, and is connected with it by screw 5.Described Electric actuator 13 is connected with the second adpting flange 18 by the first flange 14.Described the second flange 18 is connected with the first flange 14 by the first fastener assembly, and described the first fastener assembly comprises bolt 10, the first packing ring 8 and the first nut 9.Described the first flange 14 is connected with Electric actuator 13 by the second fastener assembly, and described the second fastener assembly comprises the first double-screw bolt 17, the second nut 16 and the second packing ring 15.Described the first flange 14 is provided with flange gasket 12 with the Electric actuator joint.Described valve body 22 is connected with valve gap 19 by the 3rd fastener assembly, and described the 3rd fastener assembly comprises the second double-screw bolt 20 and the 3rd nut 21.
Keying dependence Electric actuator 13 of the present utility model is with ovable valve stem 4 and is reached.When dextrorotation rotating valve rod 4, flap 2 drives barrier film 1 decline thereupon blocks path; Otherwise then valve is namely opened.
Owing to adopting the structure without stuffing box, whippy diaphragm of rubber 1 can make Korrosionsmedium and all driver parts in the runner be in the fully state of isolation, therefore have the superior corrosion-resistant and characteristics of sealing preferably, thereby stopped the drawbacks such as " run, drip, leak " of common valve.Because the runner of membrane valve is level and smooth, flow resistance is little, so can obtain larger flow.
