Description
Technical field
The utility model relates to knife gate valve technical field, particularly relates to the blade type gate valve that the sealing of a kind of full lining is exchanged.
Background technique
Known knife gate valve enters China from the eighties, less than in the vicennial time, its using scope extend to more wide all trades and professions from general field, from the coal separation of mine power plant, discharge refuse, deslagging, develop into the sewage treatment in city, developed into from general industrial pipeline the special pipeline systems such as food, health, medicine.Although knife gate valve has simple and compact for structure, reasonable in design, light-duty material-saving, sealing is reliable, operation light and flexible, volume is little, passage is smooth, flow resistance is little, the advantage such as lightweight, be widely used on the pipeline of various flowing medium, particularly slurry and the pipeline of band granule medium use, for flowing medium for a long time through knife gate valve, thus the erosion increased for knife gate valve and wearing and tearing, and traditional knife gate valve maintenance is extremely inconvenient, when some parts has been broken, the a large amount of man power and material of cost is needed to keep in repair, serious even needs whole replacing, and traditional knife gate valve sealing is also poor, easily there is the phenomenon that leaks outside, thus improve cost input, .
Model utility content
In order to overcome deficiency of the prior art, the utility model provides full lining to seal the blade type gate valve exchanged.
To achieve these goals, technical solution adopted in the utility model is:
The blade type gate valve that full lining sealing is exchanged, comprise valve body, valve rod, flashboard, valve gap and handwheel, valve body center is provided with flashboard, and valve rod one end is connected with the flashboard be arranged in valve body, the valve rod the other end is provided with handwheel, be provided with ceramic endosome between described valve body and flashboard, valve rod and flashboard are by pinned connection, and valve body upper-end surface is provided with land, land and valve body are an entirety, land is provided with support, is provided with filler outside the flashboard on valve body top, is provided with Gland and compresses above filler.
Described flashboard is also fixedly connected with valve body with stud nut by stud, stud be specially three, stud is distributed in the circle edge of flashboard, is convenient to flashboard and valve body mounts and dismounts convenient.
Described support is fixedly connected with the land of valve body with bolt and nut by bolt, and described support is leg-of-mutton support, which saves raw material, ensures the mechanical property needed.
Described handwheel, by copper nut, bearing, flat key, hand wheel lock jack panel and valve rod fixing and locking, by this setting, makes handwheel be connected with valve rod tightr.
The beneficial effects of the utility model: by adopting endosome described in the technical solution of the utility model to be that ceramic material forms, making to have more wear-resisting and corrosion resistance, avoiding the generation of the phenomenon that leaks outside, improve sealing; The utility model structural design is compact, it is little, lightweight to take up space, low price, be easy to install, wear-resisting clogging-preventing measures is perfect, be convenient to maintenance, easy to use and the life-span is long.
