Description
Technical field
This utility model belongs to intelligence instrument valve field, is specially the automatically controlled orbit ball valve of a kind of two pass movable sealing.
Background technology
In intelligence instrument (such as intellectual water meter, gas meter, flow meter) industry, existing electric-controlled ball valve is all that the single track by two O seals, and uses, it is possible to cause fluid leakage to leak in combustion gas under long-term use or low temperature.And existing electric-controlled ball valve adopts and first rotates the valve opening mode risen again, it does not have guide's pressure release, valve opening current of electric is big, falls before in the pass valve mode rotated, after sealing ring is aging, not easily fastens, there is interior leakage.Enterprise safety operation is all produced potential potential safety hazard by these, is badly in need of solving.
Utility model content
For existing electric-controlled ball valve Problems existing, the purpose of this utility model is in that to provide the automatically controlled orbit ball valve of a kind of two pass movable sealing.
The automatically controlled orbit ball valve of described a kind of two pass movable sealing, it is characterised in that include flap, auxiliary movable sealing diaphragm, the first deep groove ball bearing, helical gear, valve rod, linear bearing, valve gap, sealing ring, direct current generator, gear, the little axle of guiding, the second deep groove ball bearing, guide plate, clockwork spring assembly and movement locus groove；
Auxiliary movable sealing diaphragm is bowl structure, and big opening is fixing with valve gap to be connected, and little opening is lived with valve rod interference fit and is connected, and does upper and lower rectilinear motion and the twist motion of level 90 ° with valve rod；
Valve stem top end has a transverse holes, lead one end of little axle is connected with valve rod perpendicular fastener through this transverse holes, lead little axle the other end fastening two the second deep groove ball bearings, one of them second deep groove ball bearing steps down in the helical incline of helical gear, and another second deep groove ball bearing is in the movement locus groove of guide plate；
The movement locus groove of guide plate is the level trough of a vertical vertical channel and a transverse direction, the two groove be 90 ° vertical and be interconnected.
The automatically controlled orbit ball valve of described a kind of two pass movable sealing, it is characterized in that: during valve opening, direct current generator, gear, helical gear, linear bearing and the first deep groove ball bearing Collaboration, promote the little axle first upwards rectilinear motion of movement locus groove along guide plate that leads, then horizontal motion again, band ovable valve stem and flap first move upward simultaneously, and then half-twist completes valve opening, and tightens the clockwork spring in clockwork spring assembly；
Close movement locus and the valve opening contrast of valve, reversion direct current generator be out of gear, clockwork spring assembly rotates by promoting helical gear, the second deep groove ball bearing, thus promoting the little axle that leads by the movement locus groove elder generation horizontal motion of guide plate, then vertical downward movement again, band ovable valve stem and flap first turn round 90 ° simultaneously, then at valve rod, flap downward rectilinear motion under the combined effect of gravity and spring force, flap is made to compress sealing ring, valve closing.
Advantage of the present utility model:
1, auxiliary movable sealing diaphragm and O RunddichtringO composition double sealing, it is ensured that when using under long period of soaking or low temperature in a fluid, all do not have external leakage, and do not affect normal switch valve；
2, valve opening adopts the mode rotated again that first rises, and namely guide's pressure release fully opens valve again, reduces motor drive current, closes valve employing and first rotates the mode declined again, by the disclosure risk in gravity makes flap compression seal circle reduce of spring force and valve rod, flap.

Detailed description of the invention
In conjunction with Figure of description, this utility model example is described in detail:
Shown in Fig. 1, Fig. 4, the contact surface of flap 1 and sealing ring 8 is a sphere；Auxiliary movable sealing diaphragm 2 is in bowl structure, and big opening is fixing with valve gap 7 to be connected, and little opening is lived with valve rod 5 interference fit and is connected, and follows valve rod 5 and moves together, plays double sealing effect for valve；Linear bearing 6 and the first deep groove ball bearing 3 are linked together by certain structure, form a combination bearing；The bottom of helical gear 4 is gear, and a spiral inclined-plane is arranged at top；A transverse holes is opened on the top of valve rod 5, fastening after one end traverse transverse holes of little axle 11 that leads, the other end of little axle 11 of leading wears two the second deep groove ball bearings 12, fixed interval distance is had between two the second deep groove ball bearings 12, one of them second deep groove ball bearing 12 steps down in the helical incline of helical gear 4, another second deep groove ball bearing 12 is in the movement locus groove 15 of guide plate 13, so, valve rod 5, leads little axle 11 and two the second deep groove ball bearings 12 are just connected as a single entity.
Shown in Fig. 2, direct current generator 9 comprises reducer arrangement, has a fork in the bottom of direct current generator 9, when motor rotates forward, fork left swing, the gear on fork engages with gear 10, thus the whole valve mechanism of transmission, during motor reversal, the right pendulum of fork, the gear on fork and gear 10 disengage；Clockwork spring assembly 14 provides torsion for fast quick-closing valve, and clockwork spring is on clockwork spring assembly 14 top, and clockwork spring assembly 14 bottom is spring gear, is connected by winder, and spring gear engages all the time with helical gear 4.
Shown in Fig. 3 is guide plate 13, guide plate 13 has movement locus groove 15, movement locus groove 15 has the level trough of a vertical vertical channel and a transverse direction, the two groove is 90 ° and vertically and is interconnected, and is the movement locus of valve rod 5 top connection guiding superolateral second deep groove ball bearing 12 of little axle 11.
During valve opening, motor rotates forward, fork left swing, gear meshing gear 10 on fork, now helical gear 4 starts to turn clockwise, thus band ovable valve stem 5 is upwards for linear motion, in this process, flap 1 is side inclination to the left always, when flap 1 and sealing ring 8 are completely disengaged, namely valve rod 5 is promoted to peak, and helical gear 4 starts to promote the second deep groove ball bearing 12 to rotate, thus band ovable valve stem 5, flap 1 rotate, progressively tighten the clockwork spring in clockwork spring assembly 14 simultaneously；When, after flap 1 half-twist, stopping operating after arriving valve opening maximum position, complete valve opening.In the process, the little opening of auxiliary movable sealing diaphragm 2, in company with the first upwards rectilinear motion of valve rod 5, then does the twist motion of 90 ° again.When closing valve, motor reversal, the right pendulum of fork, the gear 10 that is out of gear on fork, helical gear 4 quickly rotates under the effect of clockwork spring torsion, thus promoting the second deep groove ball bearing 12 to rotate, also band ovable valve stem 5, flap 1 turn round 90 °, rise to the position of peak when valve rod rotation 5 goes to valve opening, stop operating, valve rod 5 makes downward rectilinear motion under the effect from gravity and spring force, makes flap 1 compress sealing ring 8, valve closing.Close valve to complete in moment.In the process, the little opening of auxiliary movable sealing diaphragm 2 first does the rotary motion of 90 ° in company with valve rod 5, then does downward rectilinear motion.
