Flap valve is widely used in building material, metallurgy, chemical industry ,electric power and other industries. As dust hopper discharge devices of all kinds of dust filters, and feeding and discharge devices of all mills, dryers and material silos,they prevent unrestrained winds from blowing in. It is of discharging completely, good sealing, light weight, simple structure, swift action and so on.
High temperature flap valve makes up for the inadequacy of existing flap valve , offers a kind of tearing open outfit of the flap valve disc with high temperature resistant online. The high temperature flap valve includes body. One side of the body mentioned has the access door. Between the body and the access door is equipped with sealing gasket. Equipped inside of the valve is valve plate, valve plate is installed in the valve body through the valve shaft and at the ends of the valve spindle bearings,the balance beam are connected at one end of valve shaft outside of the body, and on the balance beam is installed a counterweight block.
Compared with existing products, the distinctive features of this product are:
The access door can be removed conveniently, valve plate can be removed from the body as a whole. This makes more convenient replacement of valve plate, saves the maintenance time, and increases the working efficiency.
Body wall lining is castable.That different castable lining is spread on the inner wall of the valve body according to the requirement of the material can make the flap valve is suitable for various conditions.
Valve body and internal components is strong, heat resistance, no deformation and no damage caused when overheating.
Valve plate swinging is lightweight and flexible. Heavy hammer is easy to adjust, that can avoid that the valve plate opening and closing action is too big, and can prevent the material flow pulsing, do blanking evenly. Generally that there are round or curved holes in the front of valve plate makes part of the material often shed.
Valve plate is with good air tightness, valve plate shape is neat and pipe walls contact closely, at the same time that put an end to any air leakage of connecting flange and the bearing clearance.
Valve plate bearing supporting the rotary valve (including rolling and sliding bearing and so on) is sealing good, prevent dirt entering.
Valve plate is easy to inspect, tear open outfit, parts is easy to replace.
The flap valve outside box is without ball bearing, of good sealing performance, long service life and flexible unloading automatically and so on.
