Abstract
The utility model relates to a highly wear-resistant knife gate valve, which belongs to a knife gate valve and comprises a valve body, a knife gate plate and a valve seat; wherein the valve seat is positioned between the valve body and the knife gate plate to form a sealing pair, the top of the valve body is connected with a hand wheel through a valve cap, and a layer of wear-resistant sleeve is arranged on the inner wall of the fluid medium inflow end of the valve cavity. The highly wear-resistant knife gate valve has the advantages that after the layer of wear-resistant sleeve is laid outside the wall of the fluid medium channel of the valve cavity, the abrasion from the fluid to the valve cavity wall and the valve seat can be effectively prevented, so that the service life of the knife gate valve can be prolonged.
Description
Technical field
The utility model relates to the disconnecting link valve, specifically is a kind of high abrasion disconnecting link valve.
Background technique
The disconnecting link valve is the abbreviation of wafer type plate valve, and this kind valve is short with its structure length, and is in light weight, and installation and maintenance conveniently are celebrated, and are used for the low pressure pipeline transporting system mostly and use.Its valve body inner side surface of the disconnecting link valve of Chu Xianing is the concave spherical surface shape in the market, seal ring and valve body inner side surface be combined into protruding spherical shape, seal ring places the valve body inboard, closes with the movable lining of sphere.But this disconnecting link valve is in the pipe-line transportation system of sewage treatment, food and drink processing, chemical enterprise, need to carry flowing medium of different nature in the pipeline, wherein contain the material of various easy precipitations and easily to flashboard wear particle thing, therefore in use, valve is when closing, and the particulate matter that flashboard is easily accumulated stops and flashboard is in the defective of state of wear all the time.
The model utility content
The technical problem that the utility model solved is to provide a kind of body cavity wall and the nonabradable high abrasion disconnecting link of valve seat valve.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of high abrasion disconnecting link valve, comprise valve body, disconnecting link plate and valve seat, valve seat is placed between valve body and the disconnecting link plate and is used to form sealing pair, and the top of valve body links to each other with handwheel by valve gap, it is characterized in that: described body cavity is provided with one deck wear-resistant sleeve on the inwall of flowing medium inflow end.
Described wear-resistant sleeve is used to strengthen the anti-wear of valve interior wall and valve seat.
Closely adhered together between described wear-resistant sleeve and the body cavity fluidic channel walls.
Described valve seat is arranged on the wear-resistant sleeve rear side, avoids medium to wash away.
The beneficial effects of the utility model are outside the fluid medium channel wall of body cavity, paste one deck wear-resistant sleeve after, effectively barrier fluid is to the wearing and tearing of body cavity wall and valve seat, increases the working life of disconnecting link valve.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of high abrasion disconnecting link valve, comprise valve body 1, disconnecting link plate 2 and valve seat 3, valve seat 3 is placed between valve body 1 and the disconnecting link plate 2 and is used to form sealing pair, top at valve body 1 links to each other with handwheel 5 by valve gap 4, and valve body 1 and valve gap 4 join fixing by bolt, and at valve body 1 inner chamber, on the inflow end inwall of flowing medium one deck wear-resistant sleeve 6 is set, is used to strengthen the anti-wear of valve body 1 inwall.Be closely adhered together between wear-resistant sleeve 6 and the valve body 1 cavity fluid conduit wall wherein.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
