Technical field
The invention belongs to valve technology fields, and in particular to a kind of three-way cut-off valve.
Background technique
Valve can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radioactivity
The flowing of the various types fluid such as medium.Wherein, three-way cut-off valve is the control unit in fluid delivery system, have cut-off,
Adjusting, prevents the functions such as adverse current, pressure stabilizing, shunting or overflow at water conservancy diversion;Three-way cut-off valve is widely used in petroleum, chemical industry, natural
The fields such as gas, power station, metallurgy, national defence scientific research.Three-way cut-off valve compares the more runner mouths of two-way shut-off valve.Three-way valve is main
For changing medium flow direction, three-way cut-off valve it in addition to import A, outlet B, there are also commutation mouth C, have change medium flow to function
Energy.
Three-way cut-off valve is opened medium and is entered from the road junction A, flows out through the road junction B, when bypass needs medium flow field fashionable, unlatching is held
Row mechanism, spool commutation, medium goes out from the road junction A into the road junction C, when not need medium flow field fashionable for pipeline, opens executing agency, valve
Close truncation medium.
Existing three-way cut-off valve unreasonable structure, has the disadvantage that
Firstly, three-way cut-off valve has actuation time short, big feature is impacted, for this feature, existing three-way cut-off valve is not
Has reasonable buffer gear, the load that valve event is transmitted on valve support/pipeline is excessive, to what is generated by temperature change
Stress loading and electric device inertial load not can guarantee effective compensation and absorb.
Secondly, valve component can not fast quick-detach, be not easy to repair.
Again, valve flap structure design is unreasonable, and valve negotiability is to be improved.
Finally, flap, which exists, rotates with medium and tilt stuck phenomenon, abrasion and noise, and flap are led to the problem of
It is bad with the sealing of valve base chamber.
