Description
Technical field
Not having two telescopic environment-friendly type push-pull valves that leak outside is a kind of no exhaust gas and dust dischargings, stops the high-tech environment-friendly products of harmful gas to the human injury.Be mainly used on the gas pipelines such as metallurgy, electric power, thermoelectricity, coking, mine.
Background technique
At present, two telescopic push-pull valves are locked release arrangement by left valve barrel, right valve barrel, leading screw, screw, bellows, seal ring, plate, crossbeam, gear ring, sprocket wheel, base and are opened panel assembly and form.Because this structure is an open type, each output shaft has the phenomenon of leaking outside, the valve gas in the pipeline when switch to be emitted in the atmosphere.Guide rail is fixed on the base, makes the easy dust stratification of guide rail, and it is dumb to cause track roller to rotate, and influences the switch motion of valve plate, and these all are the problems that this structure exists.
The model utility content
The technical problem that the utility model solves is: overcome the problem that prior art exists, design a kind ofly open flexibly, the nothing of not fragile seal ring and long service life leaks outside pair telescopic environment-friendly type push-pull valves.
The technological scheme that its technical problem that solves the utility model adopts is: this nothing two telescopic environment-friendly type push-pull valves that leak outside, comprise main valve body, guide rail, the plate assembly, the plate upper saw pulley, the plate display unit, base assembly, the locking power device, telescopic compensator, lock bearing chamber and open the plate bearing chamber, it is characterized in that: auxiliary valve body is set at the main valve body two ends, main valve body is fixed on the base assembly, and be connected with auxiliary valve body with valve flange, blind flange is set outside auxiliary valve body, guide rail is fixed on the top of main valve body, the plate assembly is suspended in the groove of guide rail by the plate upper saw pulley, the plate display unit is fixed on the two ends of auxiliary valve body, the lower end that the locking power device is installed in main valve body is connected the rotation of drive gear ring with gear, cinder-discharging port is arranged on the base assembly, opens the plate transmission shaft, locking bearing chamber and open on the bearing of plate bearing chamber a plurality of seal rings all are set.
Described main valve body comprises two unsteady valve bodies, and the valve body that floats is provided with telescopic compensator, and whole main valve body is fixed as one, and the plate assembly places in the middle of two unsteady valve bodies, and the plate assembly is equated with the distance of two unsteady valve bodies 22.
Described on the sealing surface of valve body that floats built-up welding sealing surface alloy-layer.
Have manhole on the described blind flange that outside auxiliary valve body, is provided with.
The described a plurality of seal rings that are provided with on bearing are O-ring seals, comprise first O-ring seals and second O-ring seals that are installed in the inside and outside both sides of bearing, and three O-ring seals of device on bearing gland.
The described a plurality of seal rings that are provided with on bearing are that seal ring is y-shaped ring or v-ring.
This nothing two telescopic environment-friendly type push-pull valves that leak outside have avoided the gas in the pipeline to discharge in atmosphere when switch.And on the main valve body sealing surface hardfacing alloy layer played anticorrosion, anti-ly be stained with, wear-resisting effect.Guide rail is fixed on valve body top, reduces the guide rail dust stratification, make out the plate flexible movements, and add in the valve body bottom and to help dust emissions by cinder-discharging port.The more important thing is that plate is suspended on the guide rail, thereby keep when plate being moved laterally that distance equates between plate and the main valve body between main valve body with plate upper saw pulley fixed guide, make main valve body open crotch evenly and to open crotch big, seal ring is not fragile, increases the service life.Blind flange is set before and after on the auxiliary valve body and manhole is convenient to maintenance and inspection, changes easily damaged parts.
Compared with prior art, the nothing of the present utility model beneficial effect that two telescopic environment-friendly type push-pull valves are had that leaks outside is: each parts of valve body are added guard shield be closed, the bearing chamber of each output shaft adds the seal ring sealing, solving exhaust gas and dust is discharged in the atmosphere, stop harmful gas to the human injury, and guide rail is fixed on valve body top and has avoided a large amount of dust stratifications, and valve plate is opened flexibly.Main is keeps that distance equates that it is big to open crotch when main valve body unclamps between plate and the main valve body when plate moves laterally between main valve body, not fragile seal ring increases the service life.
