Description
Technical Field
The utility model relates to the technical field of valves, specifically a novel leak protection formula electric butterfly valve.
Background
A butterfly valve, also called a flap valve, is a regulating valve with a simple structure, and can be used for on-off control of low-pressure pipeline media, namely a valve with a closing member (a valve clack or a butterfly plate) which is a disc and rotates around a valve shaft to open and close, and the valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The butterfly valve mainly plays a role in cutting off and throttling on a pipeline and belongs to one of valves for controlling medium flowing in the pipeline, and the butterfly valve mainly achieves the purpose of opening and closing or adjusting by rotating a disc-shaped disc plate around the axis of the disc-shaped disc plate in a valve body.
However, in the case of long-term use, the butterfly valve is opened and closed frequently, which inevitably results in poor sealing effect between the butterfly plate and the valve body, leakage and the like.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel leak protection formula electric butterfly valve to solve the problem that proposes among the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a novel leak protection formula electric butterfly valve, includes valve body, valve rod and electric actuator, the bottom of valve rod is passed through the bearing frame and is installed bottom in the valve body, and the top passes the valve body with electric actuator connects, there are valve plate A and valve plate B relative both sides through mounting fixed mounting respectively on the valve rod, valve plate A and valve plate B's tip is equipped with sealing washer A and sealing washer B along the week respectively, the valve body inner wall along week respectively fixed be equipped with sealing washer A and the sealing washer B of sealing washer A and sealing washer B looks adaptation.
And the sealing ring A, the sealing check ring A, the sealing ring B and the sealing check ring B are all silica gel rings.
And the sealing ring A, the sealing check ring A, the sealing ring B and the sealing check ring B are all magnetic rings.
The side face of the valve plate A and the side face of the valve plate B blocking fluid are cambered surfaces.
Compared with the prior art, the utility model discloses the beneficial effect who reaches is: the utility model discloses in, relative both sides are passed through mounting difference fixed mounting and are had valve plate A and valve plate B on the valve rod, and electric actuator passes through the valve rod and realizes that valve plate A and valve plate B open and shut simultaneously, and the setting of two valve plates carries out double-deck assurance to sealed effect, under the condition that has a valve to appear leaking at even, another valve also can in time keep off the work of protecting, avoids the valve inefficacy.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a novel electronic butterfly valve of leak protection formula, including valve body 1, valve rod 2 and electric actuator 3, the bottom is passed through the bearing frame and is installed at 1 bottom in the valve body in the bottom of valve rod 2, and the top passes valve body 1 and is connected with electric actuator 3, it has valve plate A5 and valve plate B6 to pass through mounting 4 respectively fixed mounting in the relative both sides on the valve rod 2, valve plate A5 and valve plate B6's tip is equipped with sealing washer A7 and sealing washer B8 along week respectively, 1 inner wall of valve body is fixed being equipped with respectively along week with sealing washer A7 and sealing washer B8 looks adaptation sealing washer A9 and sealing washer B10.
The sealing ring A7, the sealing retainer ring A9, the sealing ring B8 and the sealing retainer ring B10 are all silica gel rings, and the silica gel rings are high in corrosion and aging resistance.
The sealing ring A7, the sealing retainer ring A9, the sealing ring B8 and the sealing retainer ring B10 are all magnet rings, and the adsorption of the sealing ring A7 and the sealing retainer ring A9 can be realized; and the sealing ring B8 is adsorbed with the sealing retainer B10.
The electric actuator 3 is started to drive the valve plate A5 and the valve plate B6 to be opened and closed simultaneously through the valve rod 2, and the arrangement of the two valve plates ensures the double-layer sealing effect; when the valve plate a5 and the valve plate B6 are closed, the seal ring a7 and the seal retainer a9 abut against each other, and the seal ring B8 and the seal retainer B10 abut against each other, so that a sealed state can be formed.
Example 2
Referring to fig. 5, the side of the valve plate a5 and the valve plate B6 that blocks the fluid is an arc surface, and when the fluid impacts the valve plate a5 and the valve plate B6, the arc surface enables the fluid to flow toward the periphery, so that the impact force of the fluid can be weakened, and the service life of the valve plate a5 and the valve plate B6 is prolonged.
