Abstract
The utility model discloses a wear-resistant ceramic slurry valve and belongs to valves. A support is fixed on the upper portion of a valve body. A drive device is fixed on the support. A gate plate is arranged in a valve body cavity. The upper end of the gate plate is connected with a valve rod in the support. The valve rod is connected with an output shaft of the drive device. A guide hole is formed on the gate plate. Both the upper end and the lower end of the gate plate pass through an upper port and a lower port of the valve body and are in seal connection with the upper port and the lower port of the valve body. The upper port and the lower port of the valve body are provided with upper padding, lower padding, an upper padding gland and a lower padding gland so that the valve body and the gate plate are sealed with each other. A valve seat is arranged in the valve body. A ceramic layer is arranged on the surface of the valve seat. An elastic sealing ring is arranged between the valve seat and the valve body. A ceramic casing pipe is arranged in a valve body runner. The wear-resistant ceramic slurry valve has the advantages that no slurry exists in the valve body, opening and closing of the valve can be conducted smoothly, the guide hole is arranged in the gate plate so that the gate plate is enabled to keep corresponding to the ceramic valve seat sealing face. No residue exists in the valve body cavity, and the ceramic valve seat sealing face is protected so that service life is prolonged.
Description
Technical field
The utility model belongs to a kind of valve, particularly a kind of ceramic wear-resisting slurry valve.
Background technique
Slurry valve is transporting system valve liquid-solid in the ash disposal system of a kind of magnetic separation in the mine, little choosing, mine tailing and steel mill, power plant, the gas-solid two-phase medium.The flashboard of slurry valve is a solid slab now, by moving up and down in valve pocket, plays the effect of opening and closing.It exists main deficiency to have: the bottom of (1) valve body is enclosed construction, and the medium that passes through comprises a large amount of solids, so bottom accumulated slag very easily causes valve closing not in place, effect is closed in impact.Simultaneously, thereby the exposed and medium contact of the sealing surface of flashboard bottom very easily is subjected to erosion, and the working life of sealing surface is very short; (2) owing between flashboard and the main valve body sealing configuration not being set, so very easily accumulated slag obstruction of lumen affects the operation of valve; (3) between valve seat and the flashboard for close contact cooperates, be hard sealing structure between the two namely, sealability is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, provides a kind of ceramic wear-resisting slurry valve, its good seal performance, long service life.
The purpose of this utility model is achieved through the following technical solutions: a kind of ceramic wear-resisting slurry valve, consisted of by valve assembly and drive unit, it is characterized in that: valve assembly comprises valve body, valve seat, valve rod, flashboard, support and ceramic lining-tube, the top fixed support of described valve body, drive unit is fixed on the support, be provided with flashboard in the valve body body cavity, valve rod in the upper end of flashboard and the support is connected, valve rod is connected with the output shaft of drive unit, flashboard is provided with pod apertures, flashboard upper, the upper of valve body all passed in the lower end, end opening, and with valve body on, the end opening place is tightly connected; Upper and lower mouthful of place of valve body is by upper and lower filler and upper and lower Gland; so that seal between valve body and the flashboard; be provided with valve seat in the valve body; valve base surface is provided with ceramic layer; between valve seat and the valve body elastic seal ring is installed; valve flowing channel is equipped with ceramic lining-tube, and the flashboard safety cover corresponding with flashboard installed in lower follower lower end.
Advantage of the present utility model and beneficial effect are:
Medium channel is straight under opening state, thus accumulated slag nowhere in the valve pocket, so that the keying of valve is smooth and easy;
The setting of pod apertures on the flashboard; so that no matter valve is under the state of standard-sized sheet or complete shut-down; flashboard is identical with the sealing surface of valve seat all the time; can accumulated slag in the valve body body cavity; and valve seat is provided with ceramic layer, and its sealing surface is protected, and is difficult for passing through by erosion, wearing and tearing because of solid dielectric; its sealing effect and working life are improved, and then also be significantly increased the working life of valve.
Valve flowing channel is installed ceramic lining-tube, prevents that effectively medium to the washing away of metal valve body, prolonging the working life of valve.
The flashboard safety cover is installed in lower follower lower end, and effectively the protection flashboard that stretches out the valve body part is not subjected to extraneous damage, has also avoided in the valve opening and closing process flashboard to personnel's injury.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure, 1-valve body, 2-support, 3-drive unit, 4-flashboard, 5-valve rod, 6-pod apertures, the upper filler of 7-, filler under the 8-, the upper Gland of 9-, Gland under the 10-, 11-valve seat, 12-ceramic layer, 13-elastic seal ring, 14-ceramic lining-tube, 15-flashboard safety cover.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Embodiment: as shown in Figure 1, a kind of ceramic wear-resisting slurry valve, consisted of by valve assembly and drive unit, valve assembly comprises valve body, valve seat, valve rod, flashboard, support and ceramic lining-tube, the top fixed support 2 of described valve body 1, drive unit 3 is fixed on the support 2, be provided with flashboard 4 in valve body 1 body cavity, valve rod 5 in the upper end of flashboard 4 and the support 2 is connected, valve rod 5 is connected with the output shaft of drive unit 3, flashboard 4 is provided with pod apertures 6, and the upper and lower end of flashboard 4 all passes upper and lower mouthful of valve body 1, and is tightly connected with 1 upper and lower mouthful of place of valve body; Upper and lower mouthful of place of valve body 1 is by upper and lower filler 7 and 8 and upper and lower Gland 9 and 10; so that sealing between valve body 1 and the flashboard 4; be provided with valve seat 11 in the valve body 1; valve seat 11 surfaces are provided with ceramic layer 12; between valve seat 11 and the valve body 1 elastic seal ring 13 is installed; valve body 1 runner is equipped with ceramic lining-tube 14, and the flashboard safety cover 15 corresponding with flashboard 4 installed in lower follower 10 lower ends.
Working principle of the present utility model is as follows:
Figure 1 shows that the state of valve closing, when needing to open, start drive unit, moment of torsion is exported by gearbox, and the band ovable valve stem moves down, and then flashboard is moved down, stretch out from the valve body end opening lower end of flashboard, and pod apertures enters valve pocket from the valve body epicoele simultaneously, and the utility model is namely opened; In the time of need to closing, the reverse starting drive unit, moment of torsion is exported by gearbox, moves on the band ovable valve stem, and then makes the lower end of flashboard enter valve pocket, and when pod apertures entered the valve body epicoele fully, the utility model was closed.
Behind the valve closing of the present utility model, medium can not enter the valve body body cavity because flashboard fits with sealing surface everywhere all the time, so flashboard in the process of moving up and down, can the swipe both sides of flashboard of ceramic valve seat sealing surface prevent fouling on the flashboard; Guaranteed that valve can good seal, the life-span effectively improves.
