Abstract
The utility model discloses a stop valve which comprises a valve body, a valve clack, a valve rod and a valve deck, wherein the valve body is fixedly connected with the valve deck, the valve clack is located in the valve body, one end of the valve rod penetrates through a mounting hole of the valve deck and extends to the outside, the other end of the valve rod is fixedly connected with the valve clack, a locating mechanism is arranged on the valve deck and used for fixing the valve rod, and the valve rod and the valve clack are located through split collars. The locating mechanism comprises an adjustable valve-stem nut and a set screw. A filling gland is disposed above the valve deck, one side of the valve deck is fixedly connected with one side of the filling gland through a bolt, and the other side of the valve deck is fixedly connected with the other side of the filling gland through a hinge pin with a cotter pin. A circle of filling area is arranged inside the valve deck and on the periphery of the valve rod. The valve rod penetrates through a hole on the valve deck, the filling area is filled with filling, and then the filling gland and the valve deck are fastened. One end of the valve rod is exposed outside the valve deck, and a hand wheel is disposed at a tip of the end of the valve rod. The hand wheel is fixedly connected with the valve rod through a bolt. The stop valve is high in safety performance during construction and good in sealing performance.
Description
Technical field
The utility model relates to a kind of stop valve, especially relates to a kind of stop valve that is applicable to the acids medium.
Background technique
The seal form of at present traditional stop valve has plane sealing, conical surface seal etc.; This seal form is applied in the acids medium, and sealability is good inadequately, the long-term use; Because the wearing and tearing of internal structure; Cause leakage, construction safety is exerted a certain influence, also very easily cause great economic loss.
Summary of the invention
To the deficiency of above-described existing technology, the utility model discloses a kind of nonabradable stop valve, Safety performance is high, and good seal performance.
A kind of stop valve comprises valve body, flap, valve rod, valve gap, and wherein valve body is fixedly connected with valve gap; Flap is positioned at valve body; Valve rod one end passes the valve gap mounting hole and reaches the outside, and the other end is fixedly connected with flap, and said valve gap is provided with positioning means; Said positioning means is used for fixing valve rod, and said valve rod and flap are through the divided ring location.
Wherein positioning means is adjustable Stem Mut and Cock screw.
Further, the valve gap top is provided with Gland, and valve gap is connected through bolt with Gland one side, and opposite side is fixedly connected through the bearing pin that has cotter pin.
In valve gap, valve rod is with a circle packing area outward, and valve rod is passed the hole on the valve gap, the filler in the packing area again, and after material is filled in, fastening Gland and valve gap.
Filler wherein can play the effect of firm screw rod and sealing.
Further, the valve rod termination of stretching out the outer end of valve gap is provided with handwheel.
Wherein handwheel is connected through bolt with valve rod.
When Open valve, valve rod drives flap and moves upward, and during throttle down, valve rod drives flap and moves downward, and breaks off the flow direction of medium.In whole work engineering, valve rod drives the connection flap and in valve body, moves up and down under positioning means drive guiding, guaranteed the no adhesive wear between the sealing surface, has reached good sealing effect, has also guaranteed the safety of construction.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Wherein, 1 is valve body, and 2 is flap, and 3 is valve rod, and 4 is valve gap, and 5 is divided ring, and 6 is Stem Mut, and 7 is Cock screw, and 8 is Gland, and 9 is bearing pin, and 10 is handwheel, and 11 is the flap nut.
