Valve controller valve electric actuator manufacturers

TQ Denso Series Features: TQ series of electric valve actuators is my company developed another new product. This product is suitable for small-diameter butterfly valves, ball and plug valves and so do 90 ° rotation of the valve and the like. TQ series of electric valve actuators with a new main transmission structure, the three main transmission reduction mechanism placed in the same housing, belonging valve actuators integrated structure. The series is the latest product of part-turn valve actuators for 90 ° rotary valve toward the development of a body structure. The valve actuators with 90 ° rotary valve supporting assembled into electric valve used to control the valve opening and closing. The operator can remotely control the valve in the control room, you can also operate in the field manual. The product is widely used in the use of pipeline valves to drainage, heating, power plants, chemical, food, textile, paper, pharmaceuticals, shipbuilding, steel and coal and other projects. The product has the following characteristics: 1. Small size, light weight, main drive gear level straight, level and stage Worm small teeth difference planetary gear mechanism, the triple reduction mechanism placed in the same housing, compact structure. 2. The whole case is airtight structure, all the binding sites of the housing are made of rubber O-ring, sealed and reliable performance. The product is a basic type (outdoor type), the overall pattern, the overall regulation and explosion-proof type and other structure type. 3. Bear load of parts made of high-strength materials, heat treatment, high strength, high overall carrying capacity. 4. With a stroke control mechanism, torque control mechanism, the scene opening indication mechanism and remote indication of valve opening and manual potentiometer institutions. Functional and reliable machine performance. 5. Hand Video switching to automatic switching, no switching handle, users do not have to worry about switching lever pulled forget generated errors. 6. Large junction box, junction box has two cable entry seal, wiring is very convenient. 7. It has two (on, off, one each direction) Mechanical limit screw on the housing. 8. Installation and adjustment, and easy to maintain. 9. I have recommended size coupled with the valve, in accordance with the size of the production of user requirements. 10. Product line with the state standards. · Motor: valves for motor rated running time of 10 minutes, the motor is mounted on the outer side of the box, connecting the main drive gear structure and cabinets. · Main transmission (reduction mechanism): the spur, worm and small teeth difference planetary gear mechanism. Finally, from the output shaft output power to drive the valve stem. · Stroke control mechanism: the use of a cam mechanism, and the output shaft cam synchronization, open and close each to set up two cams and micro-switches, a control motor power a lamp is turned on. · Torque control mechanism: the worm axial movement structure, the worm shaft with butterfly spring, when the electric device has a torque output, the worm shaft will produce axial movement of the compression spring butterfly (displacement), the worm shaft The axial movement of the size and magnitude is proportional to the torque output of the electric device by a rack and gear, the worm shaft runout deflection angle becomes camshaft and cam touch micro switch. When factory output torque has been raised on the product nameplate "the maximum output torque" value. · Opening instructions mechanism: for field indicates the valve opening degree. Stroke control mechanism in the top of the camshaft is equipped with a dial. · Hand electric switch: for the automatic switching mechanism, no switching handle.
