Abstract
The utility model provides a wedge sluice valve with thermostable corrosion-resistant linings, which comprises a valve body, a valve deck connected with the upper part of the valve body and a wedge valve plate matching with the drift diameter of the valve body and connected with a valve rod in the upper part. The thermostable corrosion-resistant linings are arranged in the internal cavity of the valve body and the internal cavity of the valve deck. Through setting the thermostable corrosion-resistant linings in the internal cavity of the valve body and the internal cavity of the valve deck of the wedge sluice valve, the utility model greatly enhances the performance of sluice valves in resisting high temperature and corrosion, and effectively prolongs the service life of wedge sluice valves.
Description
Technical field
The utility model relates to valve, is specifically related to a kind of wedge-type gate valve that is used for the metallurgy high furnace hot blast stove system.
Background technique
The wedge-type gate valve because of its latus rectum is big, simple in structure, easy to use, good sealing effect, and is widely used in doing in the blast-furnace hot-air furnace system gas stop valve, gas firing valve and chimney valve.And at many iron workss, because sulfur-bearing is higher in the employed coal gas, under the effect of the high sulfurous gas of high temperature, valve is subjected to seriously corroded, causes too early scrapping.Although prior art has been strengthened the decay resistance of gate valve valve plate and valve body latus rectum, its body cavity and valve gap inner chamber are subjected to corrosion and damage, and remaining influences the gate valve principal element in working life.
Summary of the invention
The purpose of this utility model is to provide a kind of wedge-type gate valve that is provided with heat-resisting lining against corrosion, with effective enhancing gate valve body cavity and valve gap inner chamber decay resistance, improves the working life of valve.
The technological scheme that realizes above-mentioned purpose is: a kind of wedge-type gate valve that is provided with heat-resisting lining against corrosion, include valve body and be connected with the perpendicular wedge type valve plate of putting valve rod, be provided with heat-resisting lining against corrosion at body cavity and valve gap inner chamber with the valve gap that is connected to the valve body upper end mutually and with valve body latus rectum phase configuration and upper end.
The technical solution of the utility model also comprises: matching with heat-resisting lining against corrosion places body cavity and valve gap internal chamber wall to be provided with lining reinforcing muscles and bones.
The utility model is arranged at the inner chamber of valve body and valve gap with refractory material, as heat-resisting and erosion-resisting lining, has strengthened the high temperature resistant and corrosion resistant performance of gate valve greatly, has effectively prolonged its working life.

Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described.
As accompanying drawing, originally the wedge-type gate valve that is provided with heat-resisting lining against corrosion includes valve body 1 and is connected with the perpendicular wedge type valve plate 4 of putting valve rod 3 with the valve gap 2 that is connected to the valve body upper end mutually and with valve body latus rectum phase configuration and upper end, is provided with heat-resisting lining against corrosion 5 at the inner chamber of valve body 1 and the inner chamber of valve gap 2.
The utility model and heat-resisting lining against corrosion match and place valve body 1 inner chamber and valve gap 2 internal chamber walls to be provided with lining reinforcing muscles and bones 6.
When this used novel concrete enforcement, heat-resisting lining against corrosion adopted the high temperature resistant and good refractory material of corrosion resistance, and thickness is arranged on 25～35mm.Lining is reinforced muscles and bones and can be adopted anchor nails commonly used to be provided with by welding fixing mode.
