Fig. 1 is wafer type Ash valve structural representation of the present utility model.
Description of reference numerals: 1. Ash valve body; 2. valve body; 3. flashboard; 4. filler; 5. Gland; 6. support; 7. valve rod; 8. Stem Mut; 9. handwheel; 10. groove; 11. guide pads; 12. positioning blocks; 13. outlet end; 14. valve seats; 15. sealing surface of seats; 16. rolling bearings.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure: this wafer type Ash valve, comprise Ash valve body 1, handwheel 9, described Ash valve body 1 comprises valve body 2, flashboard 3, filler 4, Gland 5, support 6, valve rod 7 and Stem Mut 8, wherein said handwheel 9 connection valve stem nuts 8, Stem Mut 8 is fixed on support 6, and support 6 is connected with valve body 7; Described Stem Mut 8 and valve rod 7 sockets, valve rod 7 is connected by pivot pin with flashboard 3, and flashboard 3 penetrates in the groove 10 in the middle of valve body 2; Described flashboard 3 belows are 45 degree wedge-shaped structures; The outlet end 13 of described valve body 2 is provided with certain gradient; The apical position of described valve body 2 interior grooves 10 is equipped with Gland 5, between Gland 5 and valve body 2, is provided with filler 4; Described valve body 2 inside are provided with guide pad 11 and positioning block 12.Described flashboard 3 adopts wear-resisting 20Cr13 martensite stainless steel material.
During work, by controlling the object that reaches opening and closing that moves up and down of flashboard 3.When follow-up equipment needs MEDIA FLOW fashionable, Ash valve is by manual, or electronic, or pneumatic control, transmission through Stem Mut 8, drive flashboard 3 to move up and down, flashboard 3 reaches runner mouth top, medium is unhinderedly flowed into, when needs cut off medium, by manually, or electronic, or closed pneumatic, flashboard 3 is moved downward, because 45 degree wedge-shaped structures are made in flashboard 3 belows, flashboard 3 steadily moves downward flashboard 3 under the effect of guide pad 11 and positioning block 12 in groove 10, until thoroughly close sealing, flashboard 3 switches are also accurately put in place flexibly, good seal performance.Wherein Stem Mut 8 materials are aluminum bronze, and are furnished with rolling bearing 16, and manually-operable is laborsaving, light.Lime-ash valve housing adopts cast inblock, and through ageing treatment, flashboard 3 adopts 20Cr13 martensite stainless steel material, and sealing surface of seat 15 is through grinding, more than roughness reaches 0.4 μ m; Sealing surface of seat 15 can directly process on valve body 2 (first piles cemented carbide, can select Co base cemented carbide), also valve seat 14 can be fixed on valve body 2 to whole resistance to distortion, friction resistant by being threaded into also spot welding, can guarantee flashboard 3 long-term works, medium does not leak outside.Due to the design of Ash valve employing wafer type, structure length is short, easy installation and removal.The guide pad 11 that valve body 2 is provided with and positioning block 12, can tightly paste when flashboard 3 cuts out and pay on sealing surface of seat 15, guarantees sealing and cut off well rate-of flow.Valve body 2 outlet end 13 have certain gradient, and valve body 2 lumen lowest parts, with certain angle smooth transition, do not form independently inner chamber, make product have automatic row's powder function, are difficult for accumulated powder and accumulated slag, do not need to design separately purge hole.
