The utility model has the structure that a ball valve having low torque force and an overall diameter is additionally provided with a permanent magnetic reversible synchronous motor; a motor and a gear speed reducing device are integrally combined; a shaft sleeve which is connected with a motor output shaft and a ball valve shaft and is not communicated is arranged; the shaft sleeve is provided with two positioning cams through which a normally closed inching switch for opening the valve or the inching switch for closing the valve can be pushed away at a proper position. The utility model ensures a sufficient flow area and zero flow resistance; the motor is energized in the process that the valve is opened or closed within more than ten seconds, which avoids empty power consumption and extends the service life of the motor.
Description
Technical field:
The utility model relates to a kind of switching fluid small-sized electric valving that use in fields such as air-conditioning, heating, chemical industry, environmental protection that is used for.
Background technique:
Existing air-conditioning and heating with small-sized electric two logical/three-way valve adopt following 3 kinds of patterns usually: 1. spring reset type stop valve+straight stroke electric driver (hysteresis machine driving), 2. little latus rectum zone valve+spring reset type angle stroke motor driver (hysteresis machine driving), 3. spring reset type stop valve+straight stroke electric driver (electric heating expansion driven).The stop valve circulation area is little, resistance to water-flow is big, is generally used for regulating flow, brings the switching fluid and not only increases the pump consumption but also block up slag easily, and discharge value is also very limited; Zone valve is limit by motor torsion, and for offsetting the fluid pressure influence, the circulation aperture design gets littler, and discharge value is not enough equally.Be subjected to the influence of spring reset structure, the valve of opening of hysteresis machine type driver keeps allowing the long-time stall of motor move, the valve of opening of electric heating intumescent driver keeps equally also must switching on for a long time heating, motor stall or the expander heating of switching on for a long time of switching on for a long time can cause reduction of service life, wastes electric power.
Summary of the invention:
The purpose of this utility model is to provide that a kind of circulation area is big, resistance to water-flow is zero, motor only just can be switched at valve opening or tens seconds of closing in the closed procedure, can effectively prolong electrical machinery life, avoid wasting electric power, motor and gear reducer unite two into one, effective compressed drive volume, significantly reduced the fault point that components and parts connect, the ball valve in all right manually opened use.
The utility model comprises motor, ball valve, electric capacity, drives the valve sensitive switch, closes valve sensitive switch, pad, base plate, shell, it is characterized in that motor is the reversible synchronous reducing motor of permanent magnetism, ball valve adopts the overall diameter ball valve, and the through-hole diameter of ball core guarantees that with taking over internal diameter resistance to water-flow is zero.Valve shaft and ball core all adopt the sealing of O shape circle fitted seal pad, offer 2 positioning holes on the ball valve connecting end, make things convenient for ball valve to be connected and horizontal location with the quick of driver.Be provided with an axle sleeve, axle sleeve couples together the axle of motor and ball valve, the motor axis hole of a socket magneto output shaft is arranged at axle sleeve top, the bottom is provided with the ball valve axis hole of a socket ball valve valve shaft, motor axis hole is not communicated with the ball valve axis hole, be provided with two and can drive the valve sensitive switch or close the positioning cam that the valve sensitive switch backs down normally closed in position, put in place the positioning cam on rear axle housing top of valve opening backs down out the valve sensitive switch, can make the motor outage; Put in place the positioning cam top switch valve sensitive switch of rear axle housing bottom of valve closing also can make the motor outage.
Base plate connecting end and ball valve connecting end make it can't become flexible up and down by dismountable spring clip connected, unique can rotate have only axle sleeve.
Motor and gear reducer unite two into one.Motor, drive the valve sensitive switch, close the valve sensitive switch and be fixed on the base plate with set screw.
This structure ball valve valve shaft of the present utility model can easily be reversed, valve circulation aperture equates with the adapter internal diameter, guaranteed that enough circulation areas, resistance to water-flow are zero, motor only tens seconds in valve opening or pass closed procedure just can be switched on, avoid wasting electric power, prolonged the working life of motor.Motor and gear reducer unite two into one, and have effectively compressed the driver volume, have significantly reduced the fault point that components and parts connect again.Even drive corruption, the user also easily the trip spring clip, remove driver, with the manually opened ball valve of spanner and not influence system uses.
