Abstract
The utility model discloses a novel dump valve which comprises a valve bonnet, a valve rod, a valve clack, a valve seat, a handwheel and a flange. The valve clack and the valve seat are both spherical sealed structures and the flange is an oval structure. The novel dump valve reduces the scouring to the valve seat by high-pressure medium and prolongs the service life of the valve. The novel dump valve has the advantages of simple casting process, smaller volume, scouring resistance and good sealing effect.
Description
Technical field
The utility model relates to alumina industry, is specifically related to a kind of novel slurry valve.
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 the working procedure of metallic ores such as power plant, aluminium manufacturer, coal washery, molybdenum ore, tungsten ore, be used to carry the valve of medium systems such as slurry, slag, in the lifting of valve rod, landing process, easily form and scab, general; The valve of slurry valve adopts circular flange, washes away like this and seriously causes valve to scrap easily.
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 a kind of good seal performance, the anti-a kind of novel slurry valve that washes away.
The purpose of this utility model is to realize like this, a kind of novel slurry valve comprises valve gap (1), valve rod (2), valve body (3), flap (4), valve seat (5), handwheel (6), flange (7), 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), flange (7) is arranged on an end of valve seat (5), and flange (7) is oval, long axis of ellipse size lengthening, just can not change under the prerequisite that flows to sectional area like this, there is the media flow track S to change lineal shape into, reduced medium and in valve, deposited the possibility that formation scabs, 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.
Description of drawings
Fig. 2 is the structural representation of the utility model valve seat
Embodiment
As shown in Figure 1, this slurry valve is made up of valve gap, valve rod, valve body, flap, valve seat, handwheel, valve rod and flap are fixed together during work, when handwheel drives the valve rod lifting, flap is also lifted off a seat simultaneously or is fitted with valve seat, the seal valve of flap and valve seat is ball face sealing structure, has guaranteed the stability of sealing and the anti-scouring intensity of seal valve.
Claims (3)
1, a kind of novel slurry valve comprises valve gap (1), valve rod (2), valve body (3), flap (4), valve seat (5), handwheel (6), flange (7), 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, and flange (7) is arranged on an end of valve seat (5).
