Abstract
The utility model relates to an American-standard corrugated gate valve which mainly resolves the problems that an existing gate valve leaks gas and water due to the fact that sealing performance is damaged. The American-standard corrugated gate valve comprises a valve body, a valve cover, a valve rod and an operating mechanism, wherein a gate plate is connected with the bottom of the valve rod, the gate plate is matched with a valve seat in the valve body in a switching mode, and the valve cover is divided into an upper valve cover body and a lower valve cover body which are fixedly connected through a connecting piece. The American-standard corrugated gate valve is characterized in that a metal corrugated pipe is arranged between the valve rod and the valve cover, a corrugated pipe shield is arranged between the upper valve cover body and the lower valve cover body, and the metal corrugated pipe is fixedly connected with the corrugated pipe shield. Sealing performance of the gate valve is greatly improved, and therefore the phenomena of gas leakage and water leakage are avoided fundamentally.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of American Standard ripple gate valve.
Background technique
The phenomenons such as present extensive valve in industrial uses such as chemistry, pharmacy, oil often can leak, gas leakage.The reason that causes, be mainly to seal because present valve adopts different fillers, filler hugs valve rod, when starting valve rod, valve rod and filler generation frictional heating, in the course of time, sealing is damaged, cause leak, the generation of gas leak phenomenon, Another reason is that the medium in valve generally all has corrosivity, valve rod is immersed in for a long time and produces erosion and encrustation in medium, and sealing surface is damaged, cause leak, the generation of gas leak phenomenon.
The model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of American Standard ripple gate valve, causes the problem of leaking gas, leaking thereby mainly solved existing gate valve because sealing is damaged.
The technological scheme that the utility model adopts is: a kind of American Standard ripple gate valve, comprise valve body, valve gap, valve rod and operating device, described stem bottom is connected with a flashboard, valve seat in described flashboard and valve body is that switch coordinates, described valve gap is divided into upper and lower valve gap, and is fixedly connected with by link, is provided with metal bellows between described valve rod and valve gap, be provided with bellows cover between described upper and lower valve gap, and metal bellows is fixedly connected with bellows cover.
All be provided with pad between bellows cover and bonnet and bottom flange.
Described metal bellows and bellows cover are by being welded and fixed.
Be provided with Lubricants between described valve rod and metal bellows.
The beneficial effects of the utility model are: greatly improved the sealing of this gate valve, thereby in the phenomenon of fundamentally having avoided gas leakage, having leaked.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A place enlarged view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Fig. 1 in conjunction with shown in Figure 2, a kind of American Standard ripple gate valve, comprise valve body 1, valve gap 2, valve rod 3 and operating device 4, described valve rod 3 bottoms are connected with a flashboard 5, valve seat 6 in described flashboard 5 and valve body 1 coordinates for switch, described valve gap 2 is divided into upper and lower valve gap, and be fixedly connected with by link, be provided with metal bellows 7 between described valve rod 3 and valve gap 2, be provided with bellows cover 8 between described upper and lower valve gap 2, and metal bellows 7 is fixedly connected with bellows cover 8, all is provided with pad 9 between bellows cover 8 and bonnet and bottom flange 2.Control operation mechanism 4, thereby by the switch of lifting valve rod 3 control flashboards 5 with valve seat 6.Set up bellows 7 can protect valve rod does not leak gas, leaks because of the damage of sealing in valve rod 3 outsides; Bellows cover 8 is fixedly connected with metal bellows 7, and bellows cover is fixed between upper and lower valve gap 2 by upper lower levelling plate 9, has so just completed the fixing of bellows 7, makes it can not slide.
Described metal bellows 7 and bellows cover 8 are by being welded and fixed.Certainly also can be by pasting or the means of fixation such as bolt, the utility model preferred weld is fixed.
Be provided with Lubricants between described valve rod 3 and metal bellows 7.Can guarantee so can not cause because of excessive friction between valve rod 3 and metal bellows 7 inwalls bellows 7 to damage.
The beneficial effects of the utility model are: greatly improved the sealing of this gate valve, thereby in the phenomenon of fundamentally having avoided gas leakage, having leaked.
Every technician's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this model utility; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
