Abstract
An intelligent double-sealed leak-proof butterfly valve consists of a valve body, flange plates, sealing rings, butterfly plates, valve rods, motors and a liquid draining device, wherein the valve body is a pipe; the liquid draining device is fixedly installed on the valve body through a bolt; an inner cavity is formed at the connecting part of each of the two ends of the valve body and each of the flange plates; the annular sealing rings are installed on the walls of the inner cavities; the butterfly plates are arranged inside the annular sealing rings; the butterfly plates are connected with the valve rods; the valve rods are connected with the motors, so that after the motors rotate for certain angles, the motors can drive the valve rods to drive opening or closing of the butterfly plates; the liquid draining device consists of a piston and a liquid draining pipe; the piston is arranged inside the liquid draining device; the liquid draining pipe is arranged at the middle part of one side of the liquid draining device; when a medium inside the valve body pushes the piston to move up, the medium can flow out of the liquid draining pipe. The intelligent double-sealed leak-proof butterfly valve has the advantages of simple structure, convenience in operation and good sealing and leak-proof effect.
Description
Technical field
The utility model relates to the technical field of valve, is specifically related to a kind of intelligent double-sealing anti-leakage butterfly valve.
Background technique
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, around valve shaft, rotates to reach a kind of valve of opening or closing, and on pipeline, main rising cut off and throttling use.Butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the object that opens and closes or regulate.Butterfly valve standard-sized sheet is normally less than 90 ° to complete shut-down, and butterfly valve and butterfly bar itself do not have self-lock ability, for the location of butterfly plate, on valve rod, install worm speed reducer additional.Adopt worm speed reducer, not only can make butterfly plate there is self-lock ability, butterfly plate is stopped on arbitrary position, can also improve the operating characteristics of valve.
Existing butterfly valve is all single valve plate, by the edge of valve plate, is combined realizes sealing with Sealing, and its sealability is poor.At milk, carry out after sterilizing, the particle that milk produces is attached to valve interior wall, need to clean with soda acid mixed solution, but when sterilization of milk is sterilized, soda acid mixed solution can not flow in the pipeline of milk, so having relatively high expectations to sealing anti-leak.
Model utility content
The purpose of this utility model is to provide a kind of intelligent double-sealing anti-leakage butterfly valve, have simple in structure, easy to operate, the sealing advantages such as anti-leak result is good.
The technological scheme that the utility model relates to:
Intelligent double-sealing anti-leakage butterfly valve, is comprised of valve body, flange plate, seal ring, butterfly plate, valve rod, motor and pumping equipment.
Described valve body is a pipeline, and pipeline middle part one side has a mouth of pipe, and mouth of pipe surrounding has tapped hole, pumping equipment is bolted and is placed on valve body; Described flange plate is by hexagon socket head cap screw fixed in position in valve body two ends, and the joint of valve body two ends and flange plate respectively forms an inner chamber, and described O-ring seal is placed in internal chamber wall.
Described butterfly plate is placed in O-ring seal, butterfly plate is connected with valve rod, valve rod, by the through hole having on seal ring, is connected with motor after the through hole that valve body is connected to form with flange plate, makes can be with ovable valve stem order about butterfly plate unlatching or close after electric machine rotation several angle.
Described pumping equipment is comprised of a piston and Drainage pipe, and described piston is placed in pumping equipment, and described Drainage pipe is located at pumping equipment one middle side part, and while making medium in valve body promote piston to move upward, medium can flow out from Drainage pipe.
The utility model has the advantage of: simple in structure, easy to operate, sealing anti-leak result is good etc.
Accompanying drawing explanation
Fig. 1 is complete section structural representation of the present utility model.
Wherein: 1. valve body, 2. flange plate, 3. butterfly plate, 4. valve rod, 5. seal ring, 6. motor, 7. pumping equipment, 8. piston.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, intelligent double-sealing anti-leakage butterfly valve, is comprised of valve body 1, flange plate 2, butterfly plate 3, valve rod 4, seal ring 5, motor 6 and pumping equipment 7 the utility model.
Described valve body 1 is a pipeline, and pipeline middle part one side has a mouth of pipe, and mouth of pipe surrounding has tapped hole, pumping equipment 7 is bolted and is placed on valve body 1; Described flange plate 2 is by hexagon socket head cap screw fixed in position in valve body 1 two ends, and the joint of valve body 1 two ends and flange plate 2 respectively forms an inner chamber, and described O-ring seal 5 is placed in internal chamber wall.
Described butterfly plate 3 is placed in O-ring seal 5, butterfly plate 3 is connected with valve rod 4, valve rod 4, by the through hole having on seal ring 5, is connected with motor 6 after the through hole that valve body 1 is connected to form with flange plate 2, can be with after motor 6 is turned an angle ovable valve stem 4 to order about butterfly plate 3 and opens or close.
Described pumping equipment 7 is comprised of a piston 8 and Drainage pipe, and described piston 8 is placed in pumping equipment 7, and described Drainage pipe is located at pumping equipment 7 one middle side parts, and while making medium in valve body 1 promote piston 8 to move upward, medium can flow out from Drainage pipe.
The utility model adopts two butterfly plates 3, makes butterfly valve reach the effect of double seal anti-leak; The medium that the pumping equipment 7 that can be provided with according to valve body 1 flows out is distinguished the sealing of butterfly plate 3 in butterfly valve.
