Abstract
The utility model discloses a soft seal gate valve, which comprises a valve body and a valve cover arranged on the valve body. A valve rod is arranged inside the valve body and the valve cover; one end of the valve rod extends out of the valve cover; a hand wheel is fixed at an extending end of the valve rod; a valve rod nut is connected to the other end of the valve rod and arranged inside a gate plate groove; a valve cover nut for sealing is arranged between the valve cover and the valve rod; and a sealing part for sealing is arranged on the valve cover nut. The soft seal gate valve solves the problems that a valve cover nut portion of a traditional valve is exposed outside a valve cover and easy to contact with moisture inside air to cause rusting and decrease service life, and the soft seal gate valve can be widely applied to various sealing valves.
Description
Technical field
The utility model relates to a kind of fluid pipeline valve, relates in particular to a kind of pipeline gate valve.
Background technique
Common gate valve comprises valve body, valve gap and flashboard, is provided with valve rod in valve body and valve gap, and an end of valve rod stretches out valve gap; Handwheel is fixed on the valve rod external part, and Stem Mut is connected the other end of valve rod, and Stem Mut places in the flashboard slot, is provided with the bonnet nut that seals between valve gap and valve rod.Do not add any quarantine measures on the present employed soft sealing gate valve bonnet nut, so bonnet nut there is part to expose in the valve gap outside, easily contacts with the water in air branch, produce corrosion, reduce working life, and have the gap between nut and valve rod, dust is fallen in the valve body.
The model utility content
The purpose of this utility model provides a kind of soft sealing gate valve, solves the problem of the easy corrosion of present bonnet nut.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of soft sealing gate valve, comprise valve body, valve gap and flashboard, and in valve body and valve gap, be provided with valve rod, an end of valve rod stretches out valve gap; Handwheel is fixed on the valve rod external part, and Stem Mut is connected the other end of valve rod, and Stem Mut places in the flashboard slot, is provided with the bonnet nut that seals between valve gap and valve rod; It is characterized in that: bonnet nut is hidden in valve gap, and bonnet nut is provided with the Sealing that seals.
Described Sealing is a dustproof gasket.
Described dustproof gasket preferably adopts nylon material to make.
Handwheel drives Stem Mut by valve rod, and Stem Mut moves up and down along valve rod, drives flashboard and moves up and down with Stem Mut, realizes opening or throttle down.Be seal gate valve, be provided with the bonnet nut that seals between valve gap and valve rod, bonnet nut adopts the form of hiding in valve gap, and bonnet nut is provided with the Sealing that seals.
In the technical solutions of the utility model, owing to adopt bonnet nut is hidden in valve gap, and bonnet nut is provided with the Sealing that seals, bonnet nut has been cut off and the contacting of the external world, both intercepted airborne moisture, play the dust-tight effect again, unlikely bonnet nut corrosion has prolonged product working life.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, valve body, 2, flashboard, 3, Stem Mut, 4, valve rod, 5, valve gap, 6, bonnet nut, 7, dustproof gasket, 8, handwheel.
Embodiment
