The beneficial effect that the utility model compared with prior art produces is:
This guiding lifting type insulation stopcock structure advanced person, its valve switch, valve promote and carry out synchronously.
The purpose of sealing held valve rod and then reach tightly by filler under the effect of Gland and filler gland.
The operation handwheel drives the Stem Mut rotation when rotating counterclockwise, Stem Mut drives valve rod and rises, at this moment spool 4 breaks away from the valve base sealing pair, spool and valve base sealing specific pressure reduce to zero, the rotation torque of spool is down to minimum, rail-guided pin cooperates with rail-guided circle spiral chute, makes valve rod drive spool and does the unlatching of 90 ° of rotation late gates; Otherwise when turning clockwise handwheel, Stem Mut drives valve rod and descends, rail-guided pin cooperates with rail-guided circle spiral chute, make valve rod drive 90 ° of rotations of spool do late gates and close, at this moment the secondary compression fit of spool and valve base sealing makes spool and valve seat produce seal pressure.
High-temperature steam enters in the moist closet through vent valve body is incubated.
This guiding lifting type insulation stopcock has following characteristics:
(1) owing to adopted guiding lifting type structure, realized that valve promotes switch simultaneously operating, has solved the problem of valve operation poor performance.
, (two) between Stem Mut and the bonnet cap having designed thrust-bearing between the Stem Mut valve gap support is that the switching manipulation of valve is brisk more laborsaving.
(3) than traditional lifting type insulation stopcock, the Applicable scope of guiding lifting type insulation stopcock operating mode is bigger.
This guiding lifting type insulation stopcock is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
