Abstract
The utility model discloses a blast furnace pressure equalizing and depressurizing valve easy to overhaul and maintain. The valve structurally comprises an oil cylinder, a valve rod, a ball pressure head and a valve plate, which are connected in turn, wherein the valve plate is driven by the fore and aft motion of a piston rod of the oil cylinder through the valve rod to close or open an outlet channel at the lower end of a valve body. The valve is characterized in that: a maintenance door is arranged on the valve body; an air blowing-in valve is arranged on a pipeline; a baffle ring and a riser are integrated; and a valve cover and the valve rod adopt a V-shaped combined sealing ring. The maintenance effects of high speed, safety and convenience are achieved.
Description
Affiliated field
The utility model relates to the valve in the steelmaking furnace equipment of a kind of steel enterprise, is particularly useful for the valve of the equal row pressure of furnace roof system.
Background technique
The equal row pressure of steelmaking furnace furnace roof system generally adopts a kind of reduction valve; (as shown in Figure 1), valve body one side is used the flange connecting bend, and elbow links to each other with inlet pipeline; In the valve gap of valve body upper end valve rod is housed; The space is inserted sealing material and is sealed between valve rod and the valve gap, and the valve rod upper end links to each other with the piston rod of driving oil cylinder on being fixed on valve gap, and ball-type pressure head and link and valve plate couplet company are installed in the valve rod lower end; Valve plate receives the piston rod fore and aft motion of driving oil cylinder to do the action of closing or opening the valve body lower end outlet passage through valve rod, and this valve exists following shortcoming:
1, valve plate and the connection of valve rod are to adopt several bolts to be connected to be pressed in the shelves ring of ball-type pressure head to accomplish with the standpipe on the valve plate, so the frequent bolt of opening of valves often damages the service cycle weak point.
Cumbersome must valve gap top all being lifted when 2, keeping in repair, it is time-consuming to require great effort.
Close when 3, safeguarding that to have harmful gas time that sheds in the upper and lower valve rear valve body of valve passage longer, increase engineering time.
4, the structure of underfill sealants between valve rod and the valve gap, sealing effect is bad.
Summary of the invention
The purpose of the utility model is: a kind of equal purge valve of blast furnace that can solve the easy repair and maintenance of above-mentioned shortcoming is provided.
The technological scheme of the utility model is achieved in that the structure of above-mentioned valve is done following improvement just can realize purpose; 1, the offside that on valve body, is connected with the elbow pipeline is provided with one and is used to keep in repair inner AD; Need not lift the valve gap part during maintenance, reduce maintenance difficulties, use bolton at ordinary times; The metallic cover gasket seal makes things convenient for the on-bne repair valve.2, on the elbow pipeline, set up an air and be blown into valve, open during maintenance the maintenance wicket after, be blown into valve through air and can remove coal gas in the valve body fast, shortened engineering time.3, the standpipe design all-in-one-piece on the shelves ring that is pressed in the ball-type pressure head and the valve plate also links to each other with valve plate with 8-12 bolt, makes valve plate and valve rod be connected firmly difficult drop-off.4, adopt the sealing of V-type combined seal ring between valve gap and the valve rod, the V-type combined seal ring has: V-type circle, back-up ring, spacer ring.
The beneficial effect of the utility model is: increased the connect soundness of valve rod with valve plate, strengthened the sealing of valve rod and valve gap, reduced maintenance difficulty, having realized can be fast, the effect of safety, convenient for maintaining.
