Abstract
The utility model discloses a speed reducing mechanism of a novel electric valve, which is reliable in work, low in starting voltage needed by switch-on and switch-off, short in starting time, large in output torque and small in shape size. The speed reducing mechanism comprises a valve body (1), a miniature speed reducer (2), a micromotor (3) and the like, wherein the micromotor (3) receives pulse signals and is connected with the miniature speed reducer (2); an output shaft of the miniature speed reducer (2) is provided with a gear (4); the gear is meshed with a sector gear (5); and the sector gear (5) is positioned on a rotating shaft (7). After the micromotor (3) which rotates at high speed is directly connected with the miniature speed reducer (2) to realize primary speed reduction, secondary speed reduction is realized by the sector gear (5), and multiple-time speed reduction can be realized if multiple groups of sector gears (5) are added. The speed reducing mechanism adopts a travel switch for correct positioning and in-time outage, thereby not only saving electric energy, but also realizing correct switch-off and avoiding tiny leakage caused by dislocation of switch-off.
Description
Technical field
The utility model relates to a kind of reducing gear, relates in particular to a kind of electric valve reducing gear.
Background technique
Speed reducer is the important component part of electric valve, bearing the levels of precision that control valve opens and closes used time length and control valve arrival specified position, so the function of speed reducer is crucial with the performance of constructing for valve.The kind and the form of existing electric valve reducing gear are a lot; But the monnolithic case size that a common trait is arranged is mechanism is bigger than normal; And required output torque is less, and valve opening needed voltage when closing is high, and the needed time of opening and closing is long, efficient is low.
Summary of the invention
In order to solve the problems of the technologies described above; The utility model provides a kind of reliable operation; The required starting resistor of opening and closing is low, starting time is short, ouput force is apart from big and the little electric valve reducing gear of boundary dimension is made up of valve body (1), miniature reducer (2), micro motor (3), gear (4), tooth sector (5), position limit switch (6), rotating shaft (7), it is characterized in that micro motor received pulse signal; And link to each other with miniature reducer; On the miniature reducer output shaft gear is housed, this gear is meshed with tooth sector, and tooth sector is positioned in the rotating shaft.
The beneficial effect of the utility model is: with the micro motor and the miniature reducer of high speed rotating directly be connected realize that one-level is slowed down after, again through the tooth sector double reduction, also can repeatedly slow down if install many group tooth sector additional.This kind structure can increase considerably the moment that rotating shaft drives valve accordingly, be aided with high-precision fixed bit unit simultaneously after, can reach fast, accurately drive the purpose of the open and close of ball valve.Owing to adopted miniature reducer, reducing gear monnolithic case size all declines to a great extent, thereby has saved the space in addition.Again owing to adopted multi-stage speed-reducing and large diameter tooth sector, the rotatory force brachium, the driving moment of output is big, so the voltage of required necessity of opening and closing valve has been lowered to a very low degree.Last position limit switch is accurately located, outage in time owing to adopting, and has not only saved electric energy, and has closed accurately, has avoided owing to closing the minor leakage that produces not in place.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
According to shown in Figure 1, miniature reducer (2) and micro motor (3) link, and are installed in the top of valve body (1); Gear (4) is housed on the output shaft of miniature reducer (2); Closely spaced being rotatably assorted formed at the bottom and the lid bottom of gear (4), and tooth sector (5) places up and down between the lid, and and gear (4) be meshed; Position limit switch (6) is installed in the rotating shaft (7) with tooth sector (5); When micro motor (3) rotating band actuating miniature retarder (2) slow down to rotate, be installed in gear (4) on retarder (2) output shaft and will drive tooth sector (5) and carry out secondary speed-reducing at the same time and rotate, position limit switch (6) is in order to control the swing of tooth sector (5); Tooth sector (5) can accurately be located, effectively accomplish the conducting (unlatching) of valve or end (closing).
