Abstract
The utility model relates to a pneumatic valve, which has a valve body, a valve plate, a valve rod and an air cylinder. The valve plate is combined by two symmetric pieces. Central cavity of the valve plate is provided with an internal preloaded spring. The valve body has two symmetric assistant valve bodies and a central main valve body, which are positioned and tightened by bolt. Bottom of valve channel is circular and smooth. The valve rod connected with the valve plate is installed in the valve body, and the valve rod is connected with a thrust rod on the air cylinder by a clamping block. The air cylinder has an upper cylinder hole and a lower hole. The thrush rod is provided with a limiting nut. The utility model with the characteristics of simple and proper structure, convenient use, reliable and safe operation as well as long service life and good effect in use can overcome ash obstruction and ash accumulation completely, and achieve function of rapid and automatic open and close.
Description
Technical field
The utility model relates to a kind of power plant's ash disposal system that is mainly used in, the switch gear on the medium pipelines such as mine, papermaking, chemical industry dry powder, slurry belongs to the valve technology field.
Background technique
The structural type of existing gate valve is varied, and it can be made up of different structures according to different use etc., comprises gate valves such as mechanical type, pneumatic type.The structure of most flashboards is formed and is comprised valve body, valve plate, valve rod etc., drive the switch that valve plate is realized valve by valve rod, essentially no recloser, and the valve channel bottom is non-smooth curved surface, be easy to occur blocking phenomenon again, since structural unreasonable, the inconvenience of using caused, and using effect is not good.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of rational in infrastructure, and is easy to use, can solve the blocking phenomenon that occurs easily, and realizes the Pneumatic Discharging Gate of recloser.
The purpose of this utility model is finished by following technical solution, and it mainly is made up of valve body, valve plate, valve rod and cylinder, and described valve plate is combined by two of symmetries, is mounted with preloading spring in its central cavity.
Described valve body is located and fastening forming by bolt by auxiliary valve body and a middle main valve body of two symmetries, and the valve channel bottom is slick and sly shape.
Be mounted with the valve rod that links to each other with valve plate in the described valve body, this valve rod is by linking to each other with push rod on being connected in cylinder to fixture block.
Described cylinder respectively be provided with at least one cylinder-bore up and down, on push rod, also be provided with stop nut.
The utility model compared with prior art has simple and reasonable for structurely, easy to use, safe and reliable, fundamentally eliminates card ash, fouling phenomenon, long service life, and using effect is good, has realized fast and characteristics such as auto-switch function.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing, the utility model mainly is made up of valve body 1, valve plate 2, valve rod 3 and cylinder 4 etc.Described valve plate 2 is combined by two of symmetries, is mounted with preloading spring 5 in its central cavity, but the power of closing of its pretension valve plate 2.Described valve body 1 is located and fastening forming by bolt by auxiliary valve body 11 and a middle main valve body 12 of two symmetries, and maintenance is convenient in above-mentioned valve body three pieces type design, and can guarantee that nothing leaks outside.Valve body 1, the equal built-up welding Si Tailai of valve plate 2 sealing surfaces cemented carbide, and, can guarantee zero leakage through grinding.Valve body passage bottom is slick and sly shape, does not deposit dirt, is provided with and blows block apparatus, fundamentally eliminates card ash, fouling phenomenon.
Be mounted with the valve rod 3 that links to each other with valve plate 2 in the valve body 1 described in the utility model, this valve rod is connected with the valve plate lid by splitting annulus with valve plate (spool); Valve rod 3 is also by linking to each other with push rod 7 on being connected in cylinder 4 to fixture block 6.Described cylinder 4 respectively be provided with at least one cylinder-bore 8 up and down, can distinguish the switch motion up and down that countercylinder 4 top and the bottom air inlets realize valves.On push rod 7, also be provided with stop nut 9, to guarantee accurate positioning.
Behind signal pressure input cylinder 4, on piston, produce thrust, promote push rod 7 and valve rod 3, can realize switching function fast.During action, sealing surface is a self-grind process, can guarantee sealability, is particularly suitable for the transportation of power plant's dust-removing device and siccative, slurry.
Gate valve described in the utility model is a bivalve plate gate valve, and its bore is by DN50 ~ 250, nominal pressure PN1.6 ~ 6.4MPa, and material has carbon steel and stainless steel.Be applicable to media such as dust-removing device, dry powder, slurry.
