Abstract
The utility model relates to a novel corrosion resistant lining graphite valve which solves the problems of poor corrosion resistance and poor sealing performance of various existing valves. The internal part of a valve body of the valve is lined with a graphite liner which is die-cast on the inner wall of the valve body. The lower part of a valve rod and the outer surface of a valve clack are coated with graphite, and the outer surface of the valve clack is integrated with the lower end of the valve rod. A valve cap is internally lined with graphite, and a seal ring is arranged between a body lining of the valve cap and the graphite coated outside the valve rod. The lower end of the body lining of the valve cap, the upper end of the graphite liner in the valve body and the right and the left ends of the graphite liner are provided with graphite hems which are level with a flange seal lug boss. The graphite hems are embedded into a flange annular groove to get effective protection.
Description
Technical field: the utility model relates to a kind of valve.
Background technique: existing various valve corrosion-resistant, can not be used to carry and store the pipeline and the container of corrosive materials such as acid, alkali, sealing is difficult for handling, and the flanging rapid wear of valve body both sides, corrosive material still can let out, and the corrosion valve body.
Summary of the invention: a kind of valve that has in the lining stone China ink of the utility model design, it has solved the corrosion-resistant of existing various valves existence and the problem of sealing difference.This valve includes valve body (2), valve rod (6) and flap (8); be lined with graphite lining (1) with valve interior wall die casting in valve body (2) inside; be surrounded by graphite in valve rod (6) bottom with flap (8) outer surface of valve rod lower end one; valve gap body lining lower end, valve body interior graphite lining upper end and two ends, the graphite lining left and right sides are provided with the graphite limit with neat mouthful of flange seal boss; the graphite limit is embedded in the circular groove of flange, be subjected to effective protection.Owing in valve body (2), be lined with graphite lining (1), be surrounded by graphite at valve rod (6) and flap (8) outside, so this valve has good anti-corrosion and sealing, and be fit to be installed in carry and the pipeline and container of corrosive materials such as storage acid, alkali on.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Embodiment: present embodiment is made up of graphite lining (1), valve body (2), valve gap (3), valve gap body lining (4), sealing gland (5), valve rod (6), seal ring (7), flap (8), be lined with graphite lining (1) in the inside of valve body (2), graphite lining (1) is connected with the inwall die casting of valve body (2), is surrounded by graphite in valve rod (6) bottom with flap (8) outer surface of valve rod lower end one.Valve gap is lined with graphite in (3), and graphite is connected with the die casting of valve cover body.Be provided with seal ring (7) between valve gap body lining (4) and the valve rod outsourcing graphite.Can prevent the interior corrosive material of pipeline like this from valve body top seepage, and corrode outside valve body that be provided with differential (5) in seal ring (7) top, valve rod 2 tops are provided with handwheel.Valve gap body lining lower end, valve body interior graphite lining upper end and two ends, the graphite lining left and right sides are provided with the graphite limit with neat mouthful of flange seal boss, and the graphite limit is embedded in the circular groove of flange, are subjected to effective protection.Valve gap body (4) the down flange of end flange and valve body upper end compresses mutually by bolt, forms good sealing structure, prevents the corrosive material seepage and corrodes valve body (2).
Claims (2)
1. valve, constitute by valve body, valve gap, valve gap body lining, sealing gland, valve rod and flap, valve gap body lining is connected with the inwall of valve gap, the valve rod lower end connects flap, it is characterized in that: the inside of valve body is lined with graphite lining, stem lower portion and be surrounded by graphite with the flap outer surface of valve rod lower end is lined with graphite in the valve gap.
2. valve according to claim 1 is characterized in that: be provided with seal ring between valve gap body lining and the valve rod outsourcing graphite.
