Abstract
The utility model discloses a Y-shaped stop valve which is used for gear operation; the utility model comprises a valve, a valve base, a valve flap device and a valve rod; the valve flap device comprises a flexible valve flap and a valve flap cover is arranged above the flexible valve flap. The utility model has rational structure and by adopting the flexible valve flap, the valve flap is easy to be deformed with the action of medium which is convenient for the sealing of the valve; the valve adopts a linear one which is arranged to a guide plate and the resistance of the valve is little; in this way, the valve rod can be prevented from rotating and ensured to be opened and closed flexibly.
Description
Technical field:
The utility model relates to a kind of stop valve.
Background technique:
Existing Y type stop valve, the valve flowing channel tortuosity is big, and flow resistance is big, and the structural type of flap is difficult to also guarantee that sealability is good.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the operated gear Y type stop valve of good airproof performance.
Technical solution of the present utility model is:
A kind of operated gear Y type stop valve comprises valve body, valve seat, Valve clack device, valve rod, and it is characterized in that: Valve clack device comprises Elastic valve clack, and the Elastic valve clack top is provided with the flap lid.
Valve body is once-through type.The guide plate of avoiding valve rod to rotate is set on the valve rod.
The utility model is rational in infrastructure, adopts Elastic valve clack, and flap easily produces distortion under the medium effect, be convenient to the sealing of valve, and valve body adopts once-through type, and flow resistance is little, by guide plate, can avoid valve rod to rotate, and guarantees that valve opening and closing is flexible.
