Product Description

HZ series valve electric actuators are suitable for use on multi-turn valve. They can be used for actuating and controlling the opening and closing of the valve. The operator can remotely control the valve lat controlling rogm or manual control at site. By the aid of computer, automatic operation can be also set up. The actuators can be widely used in such fields as petraleum, chemical. engineering. water industry.metalluray, marine,.light industry, food-stuff industry and so omThe Protection-grade of these products is IP54(IP67 for special order), All of the technical datafor Ahese products are in accordance with the standard GB/T24923-2010<>.The Explosion-proof grade of the Explosion-proof actuators unit whase model has the symb "B" is Fx dII BT4. The protection-grade is IP54(1P67 for special order), All of the technical data for these products are in accordance with the standard GB/T24922-2010ccTechnical reauirement of electric actuator foriexplosion-proof valyez: Should the special requirements of customers, the company also provides requlation type, integrated and AC, DC 220V different frequencies of power electric device.

Should the special requirements of customers, the company also provides regulation type, integrated and AC, DC 220V different frequencies of power electric device.

Working conditions for Basic Model HZSea Level Height: no more than 1000m

Ambient Temperature: -20℃-60℃

Relative Humidity: no more than 90%(25℃ H)

Working Circumstance: without flammable,explosive.corrosive media

Protection Grade:; IP54

Power Supply: 380v.50Hz.220V.50Hz

Working Mode: rated short time period of S2,the limited period is 10min.

Note:1. "Stall Current" in this table is the data of the motor produced by Nanyang Explosion-proof Motor Factory.2.The Max.valve stem diameter with marking the "*" is 80mm.

The electric valve actuator includes 6 parts: Motor, reducer, control mechanism, manual-electric switching mechanism, hand-wheel parts and electrical parts, the driving principle is as Figure I.

1. Motor: YDF2-W outdoor three-phase asynchronous motor, the motor adopts short-time duty, the rated continuous working time is 10 min.

2. Reducer: It is consisted of a pair of spur gear and worm gears; power of the motor is transferred to the output shaft through the reducer.

3. Control mechanism: It is consisted of the torque control mechanism, stroke control mechanism and aperture indicator, and the actuatoris used for control open and close of the valve, as well as valve location indication.

(1) The torque control mechanism (Figure II. 1): It is consisted of the crank, stop block, cam

dividing disc, support plate and jogging switch, when the output shaft receive some torque

resistance, the worm rotate and generate axial displacement to drive the crank, at the same time, the stop block generates an angular displacement, so that it is close to the cam, the support plate was raised. When torque on the output shaft is increased to specified values, the support plate is raised so that the jogging switch begins to act, disconnect the power supply, the motor stops, to achieve the control to output torque of the electric actuator.

(2) Stroke control mechanism (Figure II.2): It is consisted of decade gear set, push rod, cam and

jogging switch, for short, it is called as the counter. The working principle is that the small

driving gear in the reduction gearbox (Z=8) drive the counter. If the counter has been regulated 4 according open or close position of the valve, when the counter rotates to pre-adjusted position with the output shaft (number of circles), the cam will be rotated for 90°,which drive the jogging switch to act, disconnect the power supply, the motor stops, to achieve the control to stroke (number of circles) of the electric actuator. In order to control more rotations of valve,

the cam can rotate 180°or 270°,and then drive the jogging switch to act.

(3) Adjustable aperture indicator (Figure III): It is consisted of reduction gear set, regulation gear, valve aperture dial plate, cam, jogging switch and potentiometer. In the period of

commissioning on site, the regulation gear can be adjusted to the position needed according to

circles of the valve switch equipped, and which shall be fitted with the reduction gear set (the

stand column indicates the circles needed). When the valve is in the process of opening or

closing, the aperture dial begins rotates after deceleration, to indicate switching value of the

valve, and the indication angle shall be synchronized with switching value of the valve, used

for remote indication of the valve’s position.

1. The actuator can be installed vertically and horizontally, installation of the motor shall be not

downward, for wiring, commissioning and manual operation.

2. The tooth-type axial clearance connected to the valve shall be not less than 1-2mm.

3. After the installation, when the actuator is used for the first time, the commissioning shall be

conducted item by item according to the requirements, to ensure normal use of various parts.

4. The actuator adopts three-phase asynchronous motor used for electric actuators; the rated continuous working time is 10min, which shall be paid attention to in the period of commissioning.

5. The actuator shall be carefully handled, slightly placed and kept dry, avoid contact with corrosive materials, to prevent electrical elements and mechanical parts from being damaged.
