Description
Technical field
The utility model relates to conveying equipment for fluid substances field, especially a kind of hand stop valve of resistance to water slug.
Background technique
Along with the continuous progress of mechanization; machinery is very general in the application of fluid applications; the problem of hand stop valve poor sealing performance; owing to being subject to the strong impacts of fluid, spool often can damage, and this central module one is bad; other are also ineffective; therefore need protection, it's a pity that present product seldom has the research of this respect, need to strengthen.
Model utility content
The purpose of this utility model is the hand stop valve providing a kind of resistance to water slug; mainly through spool, kettle shape spool protecting sheathing, supporting frame to the protection of spool; first and second seal ring, O-shape seal ring, oil seal ring, damping seal ring is coordinated to improve valve body overall tightness; available protecting equipment, extends working time.
A kind of hand stop valve of resistance to water slug; comprise the valve seat offering intake tunnel; described valve seat is provided with carbon steel valve body; described valve body is provided with valve gap, described valve gap is provided with valve rod boss, in described valve rod boss, offer valve-rod cavity; in described valve-rod cavity, valve rod is installed; described valve stem tip is provided with handwheel, and described valve rod bottom is provided with spool, is provided with kettle shape spool protecting sheathing outside described spool.
Described kettle shape spool protecting sheathing is provided with the supporting frame be connected with valve interior wall.
Described spool is provided with the first seal ring be connected with kettle shape spool protecting sheathing inwall, the second seal ring is installed bottom described spool.
Described valve rod is provided with the O-shape seal ring be connected with valve-rod cavity inwall, described valve rod is also provided with the oil seal ring be connected with valve-rod cavity inwall.
Offer exhalant canal on the left of described valve body, described valve inleting water passway is provided with damping seal ring.
The beneficial effects of the utility model are: the hand stop valve of a kind of resistance to water slug of the present utility model; mainly through spool, kettle shape spool protecting sheathing, supporting frame to the protection of spool; first and second seal ring, O-shape seal ring, oil seal ring, damping seal ring is coordinated to improve valve body overall tightness; available protecting equipment, extends working time.
