For reaching above purpose, the technological scheme that the utility model adopted is: this all-sealed glasses valve clamps compensation device, comprise Electric actuator, clamp housing, the crank-bar linkage driving mechanism, screw mandrel, single-wave compensator, clamping flange and square flange and middle part fixed plate constitute, square flange is fixed on the outer end that clamps housing, clamping flange is fixed on the inner that clamps housing, single-wave compensator and middle part fixed plate ecto-entad are fixed on the middle part that clamps housing successively, Electric actuator is connected with screw mandrel by the crank-bar linkage driving mechanism, screw mandrel a week can be established many along the clamping housing, it is characterized in that being provided with telescopic stuffing box gland in the outside of screw mandrel, one end of telescopic stuffing box gland is weldingly fixed on the square flange, the other end of telescopic stuffing box gland is weldingly fixed on the fixed plate of middle part, make screw mandrel be in whole sealing status, prevent that dust from entering in the pair of nut structure of screw mandrel and corresponding connection thereof, avoid the corrosion of screw mandrel and pair of nut thereof to damage and stuck.
Described telescopic stuffing box gland, constitute by corrugated telescopic cover, left turnbuckle, right turnbuckle, gland, sealing cover and seal ring, the left and right end of corrugated telescopic cover is fixing with left and right sleeve pipe welding respectively, left and right sleeve pipe is fixing with square flange and the welding of middle part fixed plate respectively, left side turnbuckle and gland are by being bolted on the square flange, and compress seal ring, right turnbuckle and sealing cover are by being bolted on the fixed plate of middle part, and making its sealing, screw mandrel inserts in the telescopic stuffing box gland in the center hole of gland; Described screw mandrel is positive and negative silk trapezoidal thread bar, is provided with lubricant reservoir in the inner of screw mandrel between the sealing cover, fills lubricant oil in lubricant reservoir; Described corrugated telescopic cover is a stainless steel compensation sealing cover.
Described single-wave compensator welds the scalariform ring flat-plate of appearing on the stage with the connection part that clamps housing, and step-like ring flat-plate is welded on the mouth of adapter along on the outer wall, takes over to be welded on to clamp on the housing again.
The beneficial effects of the utility model are: compare with the clamping compensation device that present glasses valve uses, owing to carried out hermetically sealed to screw mandrel and corresponding linkage structure thereof, so, can prevent that dust from entering in screw mandrel and the corresponding linkage structure thereof, avoids corrosion damage and screw mandrel and pair of nut thereof stuck; The valve leak that therefore causes and environmental pollution that causes and personnel's safety thereof have also been prevented.Since fill lubricant oil in the end of screw mandrel, thus the lubricated of screw mandrel guaranteed, and further prevent corrosion.Because single-wave compensator is by step-like ring flat-plate and take over and to be welded on the valve body, so can be convenient to heat treatment, be convenient to change.More than improve, significantly prolonged the working life of glasses valve.
