Technical field
The utility model relates to the valve technology field of heating equipment, specifically, relates to a kind of high temperature resistance antiscour soft seal coal gas selector valve.
Background technique
In industrial combustion furnace system, oven adopts heat storage technology to be used for preheating gas more and more, reaches energy-conservation, reduces discharging and the object of volume increase.There is following shortcoming in existing coal gas selector valve: 1. poor sealing performance mostly, and high temperature resistant erosion resistibility is poor; 2. complex structure, changes inconvenient, and commutation number of times can not meet the demands; 3. cannot show the current valve displacement information of valve plate in running, operator cannot grasp the work state information of valve plate in real time.
Model utility content
For the deficiency that prior art exists, the utility model provides a kind of high temperature resistant, antiscour, soft seal and the coal gas selector valve of long service life.
The utility model is achieved through the following technical solutions:
A kind of high temperature resistance antiscour soft seal coal gas selector valve, comprise cylinder, housing, bulb link rod, valve plate and valve opening platform, the floor installation of described cylinder has air cylinder support, the top of described housing is by hexagon socket head cap screw fixed guide cover, described guide sleeve is fixed on guide holder by packing gland, the bottom of described housing is provided with bottom bracket, one end of described bulb link rod is fixedly connected with bulb base by bulb gland, the other end is connected with the piston shaft of described cylinder by the top of described housing, described bulb base is connected with described valve plate, the bottom of described valve plate is provided with seal ring, described seal ring is fixed on seal ring base by seal ring pressing plate, described seal ring base is movably connected on described valve opening platform by bolt, the middle and upper part of described housing is provided with control cabinet, described control cabinet is electrically connected with described bulb link rod.
Further, described control cabinet is set to LED display, for the valve displacement information of numerical monitor valve plate.
Further, described seal ring is set to O type elevated-temperature seal cushion rubber.
Further, described bulb link rod is connected by the piston shaft of connecting rod with described cylinder.
Compared with prior art, the beneficial effects of the utility model are:
1, seal ring of the present utility model is set to O type refractory seal cushion rubber, not only increases sealing of the present utility model, enhances the ability of antiscour, reduce the probability of gas leakage; And heat resistance is strong, can be high temperature resistant 600 degree, greatly extend working life of the present utility model;
2, control cabinet of the present utility model is set to LED display, and electrical connection bulb link rod, can show the working state of valve plate, make operator grasp the work state information of valve plate in real time;
3, cylinder of the present utility model can ensure the commutation number of times of equipment and stable, reliable;
4, seal arrangement of the present utility model is movably connected on valve opening platform by bolt, and it is convenient to change, and is beneficial to and extensively promotes the use of.
Accompanying drawing explanation
