Abstract
The utility model discloses a baiting valve of a spherical valve seat, which comprises a valve cover, a valve rod, a valve body, a valve clack, the valve seat and a hand wheel, wherein the valve clackand the valve seat are both of spherical sealing structures, thus reducing the scouring of the valve seat by high-voltage medium and prolonging the service life of a valve. The baiting valve of the spherical valve seat has the advantages of simple casting, reduced volume, scouring resistance and good sealing effect.
Description
Technical field
The utility model relates to alumina industry, is specifically related to a kind of discharging valve of spherical valve seat.
Background technique
Discharging valve belongs to the aluminium oxide special valve, be widely used in the pipeline of particulate materials such as alumina industry, at present in power plant, aluminium manufacturer, the coal washery, molybdenum ore, in the working procedure of metallic ores such as tungsten ore, be used for carrying slurry, the valve of medium systems such as slag, general discharging valve be sealed with plane sealing, cone seal and linear sealing etc., promote at valve rod, be easy in the landing process form fouling on the valve plate surface, cause the valve seal decreased performance, problems such as clamp, thereby produce the sealability instability, can produce continuously normal operation to it and affect.
Summary of the invention
The purpose of this utility model is exactly in order to solve the deficiency of above-mentioned present situation, to design the discharging valve of a kind of good seal performance, easy processing, non-damageable a kind of spherical valve seat.
The purpose of this utility model is achieved in that a kind of discharging valve of spherical valve seat comprises valve gap (1), valve rod (2), valve body (3), flap (4), valve seat (5), handwheel (6), and it is characterized in that: valve rod (2) is arranged on the central authorities of valve body (3); Valve rod (2) links to each other with handwheel (6); Valve rod (2) and flap (4) are fixed together; Flap (4) is ball face sealing structure with valve seat (5), even flap (4) has a small amount of swing, it still can be fitted closely with valve seat (5), can not influence sealing effect because of the swing of flap.Being provided with of spherical valve seat reduced high-pressure medium to the washing away of valve seat, and prolonged the working life of valve.
The utlity model has that casting is simple, volume reduces, anti-ly wash away, advantage of good sealing effect.
