Technical field
The present invention relates to a kind of valve, particularly relate to dress formula double containment three-pointer valve.
Background technology
Ball valve is widely used in various occasion because its fluid resistance is little. But the ball seal face of ordinary ball valve and sealing surface of seat are that this seal pressure designs given when ball valve design by desirable pressure grade by there is certain seal pressure between the two and play sealing function.
So when driving valve opening and closing, the frictional force overcome between the force of sliding friction between seal pressure and filler and valve rod will be considered, and the force of sliding friction between seal pressure accounts for the overwhelming majority of the whole frictional force of valve, thus in order to enable normal opening/shutting valve, it is necessary to input sizable keying moment; Make the increase of operation relative difficulty and cost.
In use, due to being continually changing of environment and medium temperature, pyroplastic deformation occurs that pretightning force increases or reduces to valve to make material occur, valve opening and closing element all can be caused to be stuck or occur that the situation of seepage occurs. Additional valves normally use in due to the normal wear between fatigue of materials and sealing pair, all can be gradually lowered sealing property, make be substantially reduced the service life of valve.
Summary of the invention

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.
See figures.1.and.2, upper dress formula double containment three-pointer valve, including: a valve body 100, one is positioned at the ball clack molectron 200 on valve flowing channel,
One drive mechanism 300 that is connected fixing with ball clack molectron 200, this drive mechanism 300 includes the valve rod 310 of consistent perforating branches frame 400 and valve gap 500 and the valve stem nut 340 of a connection and actuator,
Offering a back seal 311 on the shaft of valve rod 310, back seal 311 is positioned at valve bonnet seal face 510 and valve rod 310 contact position,
Also including one and be positioned at sealing mechanism 600 below valve body 310, sealing mechanism 600 fits tightly in valve body sealing surface 110.
Valve rod 310 end is fixing connects hinge block 320, and hinge block 320 is connected fixing with ball clack molectron 200 for described valve rod 310 so that valve rod 310 and ball clack molectron 200 link.
With reference to Fig. 5 a and Fig. 5 b, two pieces of hinges 321 that above-mentioned hinge block 320 is connect by axle are constituted, and hinge 321 one end arranges a pin shaft hole 322, and the other end arranges a shaft-jointed hole 323, and fixing axle 324 is connected fixing to hinge block and valve rod after running through shaft-jointed hole, stem through-hole; Bearing pin 325 is connected fixing to hinge block and ball clack Macintosh after running through pin shaft hole, ball clack molectron.
With reference to Fig. 3, Fig. 4 a, shown in Fig. 4 b and Fig. 4 c, valve rod 310 is further opened with stopping means 330, stopping means 330 includes locating slot 331 and a spacing gathering sill 332, wherein spacing gathering sill 332 is in type, and valve stem nut 340 arranges two alignment pin pilot holes 342 and motion thread 341, and valve rod 310 end and valve stem nut 340 are connected by screw thread pair and are fitted in support 400.
Alignment pin 333 is positioned in alignment pin pilot hole 342 after locating slot 330, and spacer pin 334 is fixed on support, is arranged in spacing gathering sill 332, and valve stem nut 340 is connected to actuator;
Also include a localizer 350, localizer 350 is sleeved on valve stem nut 340, wherein also offering an alignment pin calibration gathering sill 351 on localizer 350, alignment pin calibration gathering sill 351 in ball valve work process, separates with valve stem nut as valve rod and closes action with conjunction and use.
Fig. 6 a is valve rod state diagram when moving in a circle, Fig. 6 b is valve rod 310 state diagram when axially moving, when valve stem nut 340 is moved in a circle by actuator, localizer 350 controls alignment pin action, valve rod and valve stem nut is done clutch action, controls to determine valve rod and axially moves and 1/4 week circular motion.
The operation principle of valve rod and valve stem nut is: when valve is closed, spacer pin is positioned at the spacing gathering sill upper end of valve rod, and it is parallel in the groove of valve rod longitudinal center line, the valve stem nut now rotated does telemechanical vertically upward by screw thread pair band ovable valve stem, makes sealing mechanism depart from valve body sealing surface by drive mechanism;
When the spacer pin on valve rod runs the groove being perpendicular to valve rod longitudinal center line to spacing gathering sill, can not be moved upward by fixing spacer pin restriction valve rod, now alignment pin controls to make alignment pin move in valve rod locating slot by localizer, make valve rod together with valve stem nut pin joint, now valve stem nut band ovable valve stem does axial rotation motion, makes sealing member rotate 1/4 thoughtful open position by drive mechanism;
Now spacing gathering sill is perpendicular to the trenches end of valve rod longitudinal center line, valve stem nut continues motion makes alignment pin depart from the locating slot of valve rod, valve stem nut does upward vertical movement by screw thread pair band ovable valve stem and contacts with valve bonnet seal face to valve stem seal face, realize back seal function, now fixing spacer pin is positioned at spacing gathering sill lower end, being parallel in the groove of valve rod longitudinal center line, whole valve opening process terminates;
In like manner, when valve closing by valve stem nut does counter rotational movement, whole closing process is contrary to the above.
Valve rod 310 in drive mechanism 300, spacing gathering sill 332 and locating slot 331, valve stem nut 340, it is arranged on the alignment pin 333 in valve stem nut pilot hole 342, and spacer pin 334 all designs in bracket cavity 410, by, in the bracket cavity 410 that O 411 is enclosed in, being filled with lubricant in bracket cavity 410, enable drive system at full airborne dust, have in the adverse circumstances of etchant gas also can flexible operation slim and graceful, safe and reliable.
