The utility model is in view of the above-mentioned problems, propose new technical scheme, by being provided with large aperture in ball valve water side
Siphunculus, the ball valve water side are provided with seal plate, realize the purpose of counterflow-preventing.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model be to provide for it is a kind of reasonable in design, anti-
The ball valve of adverse current, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme to realize：
It is achieved in that during the utility model：The ball valve is made up of stainless steel material, and the ball valve water side is provided with big
Aperture through hole, the ball valve water side are provided with seal plate, and the seal plate upper and lower ends are provided with push rod, the other end of the push rod
It is connected with bindiny mechanism, the bindiny mechanism includes spring and push pedal, and the spring one end is connected with the bindiny mechanism left side, another
End on the left of push pedal with being connected, and the push pedal passes on left steel wire and is connected with valve rod, and right side is connected with push rod.
By using above-mentioned technical proposal：The ball valve material uses stainless steel, can significantly prevent from giving birth to
The phenomenon of rust, the ball valve water side are provided with seal plate, can effectively prevent the appearance of fluid reflux phenomenon, the seal plate
Connected by bindiny mechanism, realize seal plate and valve ball operation simultaneously, it is effective to ensure the accurate of fluid throughput.
Preferably, the ball valve water inlet end is provided with screen pack.
By using above-mentioned technical proposal：By being provided with screen pack in ball valve water inlet end, effectively impurity can be prevented to enter
Enter valve body, make more pure by the fluid of ball valve, each tie point of ball valve will not be caused the phenomenon corroded occur, improve and set
Standby service life.
Preferably, the sealing plate surface is provided with rubber
By using above-mentioned technical proposal：By being provided with rubber in sealing plate surface, fluid can be effectively reduced to only
Water plate washes away, and reduces seal plate and the phase mutual friction of ball valve water side, causes the abrasion on surface, and it is service life to improve equipment.
Preferably, the push rod is connected by bindiny mechanism with push pedal.
Preferably, the steel wire is connected by bindiny mechanism with push pedal.
Preferably, the push rod, steel wire and the tie point of push pedal are the middle part of push pedal.
By using above-mentioned technical proposal：Seal plate is controlled by bindiny mechanism, accomplishes both seal plate and valve ball work
Make state consistency, more effectively reach the purpose of counterflow-preventing.
The utility model has the advantage of：1. the ball valve water side is provided with seal plate, fluid can be effectively prevented to return
The appearance of flow phenomenon, the seal plate are connected by bindiny mechanism, realize seal plate and valve ball operation simultaneously, effective to ensure stream
Body throughput it is accurate.2. by being provided with screen pack in ball valve water inlet end, impurity is effectively blocked into valve body and corrodes valve body,
Improve the service life of equipment.
