Background technique
At present the main structure of electric actuator forms wherein by motor 1, driving mechanism 2, output mechanism 3 that motor 1 is direct current or AC motor as shown in Figure 1, for final controlling element provides power source.Driving mechanism 2 mainly is made up of some gears, increases the effect of driving force by having slowed down, and so just can select the bigger load of less motor driving for use.Output mechanism 3 mainly is made up of some gears, axostylus axostyle, and the ability of certain deceleration force amplifier is generally also arranged, and its output form has: rotary-type output see Fig. 4, straight line type back and forth output see Fig. 5.Motor 1 drive transmission device 2, driving mechanism 2 drive output mechanism 3 actions, and the output of output mechanism 3 can link with valve, makes common valve become electric valve, as requested by controlling motor 1 running or stopping forward or reverse; Opening or closing of final realization valve.
But because existing electric actuator, driving mechanism 2, even output mechanism 3 is mostly seen Fig. 3 by the deceleration force amplifier mechanism that many gears are formed, thereby the output position speed per hour degree that motor 1 is driven into output mechanism 3 is very slow, fast also need one of revolution in several seconds or several second back and forth, thereby common electric actuator causes when driving valve working the unlatching of valve, shut-in time oversize, this makes when the common electric final controlling element is used in its important application-electric valve field, can be subjected to many restrictions, as the filling measurement occasion; Even can not use, control as the outlet valve that boiling water is supplied with, close slowly and will scald the people, another causes waste exactly.
Certainly the action of well-known solenoid valve is moment, fast, but because strength limited (comparing) on its intrinsic defective-electromagnet principle with motor driving, thereby when in many occasions such as water fouling, water, impurity being arranged, action is very unreliable, how not only reaching the quick acting of solenoid valve but also possessing the reliability that electric actuator is arranged becomes target to be achieved is arranged.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of Quickacting electric actuator is provided, make mortor operated valve folding more promptly become possibility.
The object of the present invention is achieved like this:
Quickacting electric actuator comprises motor 4, driving mechanism, output mechanism 8; Wherein, motor is by the driving mechanism transferring power, and then promotion output mechanism 8 motions, it is characterized in that: described driving mechanism is made of main transmission loop 13 and auxiliary driving loop 12, and main transmission loop 13 comprises two-way back stop mechanism 5, main drive gear 6, clutch 7, the output mechanism 8 of polyphone; Auxiliary driving loop 12 comprises permanent torsion mechanism 10, the auxiliary drive gear 11 of polyphone; One end in major and minor transmission loop meshes with same motor 4 rotatingshafts respectively, acceptance is from the power of motor 4, the disengagement of auxiliary driving loop 12 the other end solenoidoperated cluthes 7 is with closed, and the left end of clutch 7 is accepted the power of main drive gear 6, and right-hand member is to output mechanism 8 outputting powers; Output mechanism 8 in the main transmission loop 13 is provided with spring 9, spring 9 one ends are fixed on and are immovable point on final controlling element housing or the valve body, the other end is attached on the output shaft of output mechanism 8 or is attached on the valve rod of valve body, play the output shaft of promotion output mechanism 8 or the valve rod of valve body and reset fast, so that make the valve can quick closedown.
The two-way back stop mechanism 5 on the main transmission loop 13 and the order of connection of main drive gear 6 can be put upside down.Difference only is to slow down after slowing down still earlier, and its function is not influenced.
The permanent torsion mechanism 10 on the auxiliary driving loop 12 and the order of connection of auxiliary drive gear 11 can be put upside down.Difference only is to slow down after slowing down still earlier, and its function is not influenced.
Described main drive gear 6 is made up of the plurality of gears engagement.
Described auxiliary drive gear 11 is made up of the plurality of gears engagement.
Described output mechanism 8 mainly is to be rigidly connected by gear and output shaft to be one, and output shaft forms rotary-type output; Or gear and tooth bar engagement composition, tooth bar forms linear reciprocation output as axostylus axostyle.
Described clutch 7 is three terminal structures: power intake 61, clutch end 62, the closed control end 63 of disengaging; Power intake 62 links with the output terminal of main drive gear 6, and clutch end 62 links with the input end of output mechanism 8, and the output terminal that breaks away from closed control end 63 and auxiliary drive gear 11 links.
Described two-way back stop mechanism is a two ends mechanism: power intake 90, clutch end 98.It is by gear 91,92,93, ratchet 94, and ratchet 95, axle 96, ratchet 97 is formed; Gear 93, ratchet 94, ratchet 97, output terminal 98 and axle 96 rigid joint, input end 90 is gear 91 engaging gears 92, gear 92 is a ring gear, ring is provided with ratchet in it, ratchet is by 93,94 rotations of 97 driven gears of the ratchet on the axle 96, the rotation of gear 93 is the rotation of clutch end 98, ratchet 95 and ratchet 94 engagements.
Described permanent torsion mechanism 10 is a both-end mechanism: input end, output terminal; The input end output terminal connects through the engaging force device for limiting.
Described engaging force device for limiting is formed or is made up of moving tooth mechanism by one group of friction wheel.
The function of permanent torsion mechanism is: when the forward and reverse running of input end, the suffered resistance of output terminal is during greater than the torsion of certain particular value, and output terminal will not turn round, and input end and output terminal be sliding and running, and input end moves at this moment, output terminal is static; When the suffered resistance of output terminal during less than certain particular value, output terminal will be followed forward and reverse running of input end and be turned round, has the ability of certain promotion load this moment, thereby after the control action of having finished clutch, can stop again because the resistance that auxiliary driving loop promotion clutch is obstructed and can't remains in operation and be brought after putting in place to motor movement.
Well-known common valve is than faster when driving valve in use, and for example as long as move very little angle water tap with regard to water outlet, the big more water outlet of operating angle is just big more certainly; But when closing valve, especially after water tap was opened fully, the small angle that only closes any was otiose, can only be could close valve after complete shut-down puts in place, that is to say that common valve mostly has the ability of opening soon and do not have the ability of quick closing valve.Can select the better valve of certain opening speed, solve the quick unlatching in the electric actuator drive valve working; Common optional stop valve of this valve or ball valve, thereby the problem of opening soon is can compare by the selection of valve to be easier to realize.Therefore, how making the electric valve can quick closedown, be the present invention-Quickacting electric actuator root problem to be solved.
Basic thought of the present invention is: motor finally promotes output mechanism by driving mechanism is positioned at attached to the spring on the output mechanism valve opening and compression, thereby retracting spring makes the valve quick closedown when closing valve, it is instantaneous that this closing valve time becomes the fastest some seconds time that does not originally have spring, reached the closing velocity of solenoid valve.
The problem that thereupon needs to solve is:
Oppositely do not promote driving mechanism 6 and motor 4 when spring 9 is resetted,, improve reset speed, need increase clutches 7 in main drive gear 6 backs so to alleviate spring 9 resistance that resets.
For behind the valve complete opening, during motor 4 supply disconnectons, still can keep the enable possition of valve, and can not cause valve to be closed owing to the reset capability of spring 9, need to increase two-way back stop mechanism 5 so.
Need additionaling power to promote because clutch 7 is thrown off closed control end, need to increase the auxiliary drive gear 11 auxiliary clutches 7 that promote so and finish closure or disengagement, and drive by same motor 4 to finish disengagement, closed action.But after clutch 9 disengagements or closure are put in place, the motion that is the control end of clutch has the high-low limit position, put in place and promptly arrived the upper limit or lower position, also promptly after putting in place, clutch will be obstructed, the opposite force that is obstructed will stop motor to remain in operation, because this moment, motor 4 also need promote main drive gear 6 work, so also need increase permanent torsion mechanism 10 in auxiliary driving loop 12, after putting in place, auxiliary driving drive circuit clutch is obstructed the influence that the main transmission loop is worked on to overcome.
Compared with prior art, the invention has the beneficial effects as follows:
1, by increasing spring, adds the speed of fast valve;
2, by increasing clutch, realize resetting fast when spring discharges;
3, by adding two-way back stop mechanism, realize the normal transmission and the maintenance after the length of spring compressed of forward torsion, the forward and reverse running of assurance motor can both move, so that the control of clutch, reaches and makes the valve effect of closure or openness stably;
4, by adding permanent torsion mechanism, make the auxiliary driving loop after the task of finishing the solenoidoperated cluthes folding, break away from influence to motor;
5, by driving mechanism being divided into major and minor two-way, realized compression and maintenance that same motor can control spring, that can realize again that spring discharges resets fast, and then affacts output mechanism, drives external valve body action, the actuation time of shortening mortor operated valve.
In a word, integrated application by above-mentioned several technological means, the closing speed that makes Quickacting electric actuator of the present invention reach solenoid valve is to close moment, the advantage that has kept the functional reliability of electric actuator simultaneously, manyly not only require speed, but also requiring reliable water valve control field, as filling liquid metering, instrument and apparatus occasion, boiling water supply with automatically the field and various before use solenoid valves but insecure occasion is with a wide range of applications.

With reference to the accompanying drawings, the present invention is further described:
Referring to accompanying drawing 2, Quickacting electric actuator structural representation of the present invention; Quickacting electric actuator comprises motor 4, driving mechanism, output mechanism 8; Wherein, motor is by the driving mechanism transferring power, and then the motion of promotion output mechanism 8, it is characterized in that: described driving mechanism is made of main transmission loop 13 and auxiliary driving loop 12, and main transmission loop 13 comprises two-way back stop mechanism 5, main drive gear 6, clutch 7, the output mechanism 8 of polyphone; Auxiliary driving loop 12 comprises permanent torsion mechanism 10, the auxiliary drive gear 11 of polyphone; One end in major and minor transmission loop meshes with same motor 4 rotatingshafts respectively, acceptance is from the power of motor 4, the disengagement of auxiliary driving loop 12 the other end solenoidoperated cluthes 7 is with closed, and the left end of clutch 7 is accepted the power of main drive gear 6, and right-hand member is to output mechanism 8 outputting powers; Output mechanism 8 in the main transmission loop 13 is provided with spring 9, spring 9 one ends are fixed on and are immovable point on final controlling element housing or the valve body, the other end is attached on the output shaft of output mechanism 8 or is attached on the valve rod of valve body, play the output shaft of promotion output mechanism 8 or the valve rod of valve body and reset fast, so that make the valve can quick closedown.
Referring to the clutch configuration schematic representation among accompanying drawing 6 the present invention; Described clutch 7 is three terminal structures: power intake 61, clutch end 62, the closed control end 63 of disengaging.This clutch has the effect that torsion is transmitted in closed back, will make main transmission loop 13 be divided into two mutual incoherent parts after the disengagement, promptly no longer has the effect of transmitting torsion, and spring 9 is resetted fast becomes possibility.Quiet clutch gear 28 in Fig. 3 example, moving clutch gear 29, voussoir 37 is formed three end clutch examples, quiet clutch gear 28 is a power intake, moving clutch gear 29 is a clutch end, voussoir 37 is for throwing off the interlock control end, and after voussoir moving clutch gear 29 of 37 compressings and quiet clutch gear 28 interlocks, then quiet clutch gear 28 has to moving clutch gear 29 transferring power abilities.Quiet clutch gear 28 and moving clutch gear 29 common slips rotate on the same axle.
Referring to the two-way back stop mechanism schematic representation among accompanying drawing 7 the present invention; Power intake 90, clutch end 98.It is by gear 91,92,93, ratchet 94, and ratchet 95, axle 96, ratchet 97 is formed; Gear 93, ratchet 94, ratchet 97, output terminal 98 and axle 96 rigid joint, input end 90 is gear 91 engaging gears 92, gear 92 is a ring gear, ring is provided with ratchet in it, ratchet is by 93,94 rotations of 97 driven gears of the ratchet on the axle 96, the rotation of gear 93 is the rotation of clutch end 98, ratchet 95 and ratchet 94 engagements.Two-way back stop mechanism among the present invention, it can be one group of ratchet.Power intake 90 is that gear 91, clutch end 93 are gear 98, when input end 90 is rotated counterclockwise, engaging gear 92 rotates, because ratchet 94, gear 93 and axle 96 rigid unitary, again because the unidirectional non-return effect of ratchet 97 on the axle 96, this moment axle 96 will be followed gear 92 and be turned clockwise synchronously, the non-return function of ratchet 94, ratchet 95 is inoperative at this moment, thereby the power of 90 input ends is delivered to output terminal 98 outputting powers by gear 92, ratchet 97, axle 96, gear 93 at this moment, and this moment, output terminal 98 was for turning clockwise; When being subjected to opposition, output terminal 98 force its gear 93 to be rotated counterclockwise, this moment is because the check of ratchet 97 and 92, main is because 94 and 95 non-return effect, make that output terminal 98 is that gear 93 can't oppositely promptly be rotated counterclockwise, thereby this two-way back stop mechanism has the torsion of unidirectional delivery power intake 90, stops the ability of clutch end 98 antiports simultaneously; But this two-way back stop mechanism also has power intake 90 antiports, and do not influence the function of output state, when power intake 90 clockwise rotates, be allowed to, certainly the power intake 90 of this moment does not pass through 92 to clutch end 98 transferring power, power intake 90 is driven gear 92 sliding and running on ratchet 97 just, and 90 pairs of output states of power intake of this moment are influence not; Because power intake 90 can be along contrary bidirectional movement, so we are called two-way back stop mechanism to it.
Referring to the permanent torsion mechanism schematic representation of the frictional among accompanying drawing 8 the present invention: gear 102 and friction wheel 103 rigid joint, friction wheel 104 and gear 105 rigid connections, friction wheel 103 and friction wheel 104 frictionally transferring power, when output terminal 106 is that gear 105 suffered resistances will taken turns sliding and running on 104 greater than wheel 103 and wheel 105 transferable maximum static friction torsion hour wheels 103, only at required outputting torsion less than friction during torsion, the transmission of motion just can normally be carried out, this transferable acrotorque value is constant, thereby we call permanent torsion mechanism to it so long
Referring to the permanent torsion mechanism schematic representation of the moving tooth type among accompanying drawing 9 the present invention: gear 116 is by axle 115 and elasticity double wedge 114 rigid connections, elasticity double wedge 114 can move by the slip moving tooth on the interior rake tooth 113 of gear 112, when 117 bringing onto load torsion of output terminal during less than certain value, input end 110 is gear 111 driven gears 112, gear 112 drives elasticity double wedge 114, makes the certain torsion of gear 116 outputs by axle 115; When 117 bringing onto load torsion of output terminal during greater than certain value, the interior rake tooth 113 of gear 112 will be oppressed 114 distortion of elasticity double wedge, and with the moving tooth sliding and running, motion can't be transmitted, its maximum transferable torsion also is constant certain value, thereby also claims permanent torsion mechanism.Described elasticity double wedge 114 can be several according to transmitting the torsion needs.
Referring to accompanying drawing 10, one embodiment of the present of invention structural representation; In the present embodiment: the reducing gear that described main drive gear is made up of intermediate gear 22 or plurality of gears is formed.The reducing gear that described auxiliary drive gear is made up of intermediate gear 41 or plurality of gears is formed.Described permanent torsion mechanism is made up of intermediate friction wheel 39, intermediate friction wheel 40, and it can transmit certain torsion; Intermediate friction wheel 40 will take turns 39 with maximum force of sliding friction sliding and running with intermediate friction when middle friction wheel 39 is obstructed, and this moment, intermediate friction wheel 39 was with static.Described two-way back stop mechanism is made up of unidirectional sliding gear 23, single direction ratchet 24, single direction ratchet 25, ratchet 26, intermediate gear 27, and principle is referring to Fig. 8.Described clutch 7 is made up of quiet clutch gear 28, moving clutch gear 29, voussoir 37, last block 42, following block 43.Described output mechanism is made up of intermediate gear 30, output shaft tooth bar 31, positioning rod 33, sensitive switch 34.

Embodiment's quick-action final controlling element is up or open the valve process:
When motor 20 forwards (this example is clockwise) rotate, drive motor gear 21, by intermediate gear 41, intermediate friction wheel 40,39, connecting rod wheel 38 moves upward voussoir 37, compress moving clutch gear 29 by voussoir 37, itself and quiet clutch gear 28 are meshed, thereby make quiet clutch gear 28, moving clutch gear 29 has the ability of transmission torsion, when connecting rod wheel 38 rises to when being blocked by last block 42, voussoir 37 will no longer move upward, friction wheel 40 will be rotated further this moment, friction wheel 39 is with static, two-wheeled will be in the sliding friction campaign, not influence motor 20 and drive main transmission loop works in the example.
Descending or the pass valve process of embodiment's quick-action final controlling element:
When motor 20 reverse (this example is counterclockwise) rotates, driving motor gear 21 rotates counterclockwise, by intermediate gear 41, intermediate friction wheel 40, intermediate friction is taken turns 39 drivening rods wheel 38 and is moved downward, by voussoir 37 clutch gear 29 and quiet clutch gear 28 are separated from, quiet clutch gear 28 and moving clutch gear 29 are no longer meshed, output shaft tooth bar 31 will move under the effect of spring 32 at this moment, intermediate gear 30, moving clutch gear 29 idle running, so output shaft tooth bar 31 moves downward fast, the drive valve rod moves down and makes valve closing, also drive simultaneously positioning rod 33 and throw off sensitive switch 34, allow motor 20 stop operating this moment, and whole pass valve process is finished.
