Description
Technical field
The utility model relates to knife gate valve technical field, particularly relates to a kind of full lining blade type gate valve.
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 are 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, need to spend a large amount of man power and materials, improve cost.
Model utility content
In order to overcome deficiency of the prior art, the utility model provides a kind of full lining blade type gate valve.
To achieve these goals, technical solution adopted in the utility model is:
A kind of full lining blade type gate valve, comprise valve body, valve rod, flashboard, valve gap and handwheel, valve rod one end is connected with the flashboard be arranged in valve body, the valve rod the other end is provided with handwheel, valve body upper end is fixedly connected with valve gap by stud one and nut, the endosome of polyurethane is installed between described valve body and flashboard, wherein valve body adopts the casting of flanged type Split type precision, the endosome of polyurethane has corrosion-resistant, wear-resistant and be not stained with the effect of slag, flashboard is that stainless steel is made, stainless steel flashboard thus favourable preventing corrodes the seal leakage caused, fine-grinding and polishing process can obtain better sealing effect, valve rod is made up of upper valve rod and lower valve rod, upper valve rod and lower valve rod pass through pinned connection, filler is had at the valve rod overcoat of endosome upper end, stuffing-box is also precision casting, filler compresses with Gland, copper nut is passed through between upper valve rod and handwheel, bearing, flat key, hand wheel lock jack panel fixing and locking, flashboard is also fixedly connected with valve body by stud.
The pivot pin of described upper valve rod and the joint of lower valve rod is higher than Gland.
Described valve gap is provided with leg-of-mutton support, and leg-of-mutton support saves raw material, ensures the mechanical property needed.
Described stud two be specially three, and stud two is distributed in the circle edge of flashboard.
The beneficial effects of the utility model: by adopting the endosome being provided with polyurethane described in the technical solution of the utility model between valve body and flashboard, thus make the utility model more corrosion-resistant and wear-resisting; 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model.
