Abstract
A regulation type throttling plunger valve relates to a valve, in particular to a plunger valve. The regulation type throttling plunger valve is composed of a valve body, a throttling plunger, a porous frame, a flexible graphite sealing ring, a valve rod, a valve cover, flexible graphite, a filler gland and a handwheel. The porous frame is mounted in the valve body. The flexible graphite sealing ring is arranged in the valve seat of the porous frame. The throttling plunger is arranged in the flexible graphite sealing ring. The valve rod is connected to the upper end of the throttling plunger. The valve cover is mounted on the upper portion of the valve body. The filler gland is mounted on the upper portion of the valve cover. The valve rod is arranged in the holes of the valve cover and the filler gland. The flexible graphite is arranged between the valve rod and the valve cover. Besides, the handwheel is mounted on the upper end of the valve rod. The utility model solves the problem of liquid leakage of the existing similar product due to non-tight sealing.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of plunger valve.
Background technique
There is the shortcoming of sealing difference in existing valve, especially after long-time the use, owing to have the grains of sand in the sewage, can cause between valve seat and the plunger cut to occur in the effluent discharge pipeline, causes poorly sealedly, the problem of leak of liquid occurs.
The model utility content
