Product Description

The DZTB series of electric valve actuator is a new generation of products independently developed by our company by improving and perfecting structures, optimizing protective performance and key parts on original mature products, it has some advantages, such as: Compact structure, small volume, beautiful appearance and stable performance etc. The excellent protective grade can meet demands of many designs :Flame-proof type, global switch-type and global regulation-type designs.

DZTB series of products are used to control open and close of the valves. The products can be used for brake valve, stop valve, shutoff valve, and diaphragm valve, the derived products can be used for ball valve, butterfly valve and throttle etc., the product can accurately act according to the control instruction, therefore it is necessary driving unit for achieving remote control, centralized control and automatic control.

Performance of the product meets the provisions of JB/T8528-1997 (The technical conditions for electric units of common valves). The flame-proof performance meets the requirements of GB3836.1-2000(the electrical equipment used for explosive gas atmosphere, Part 1: General requirements), GB3836.2-2000(the electrical equipment used for explosive gas atmosphere, Part 2: flame-proof type “d”), as well as JB/t8529-1997 (the technical conditions for flame-proof type electric units).

1. Power supply: The motor is three-phase AC380V, 50 Hz. The control is two-phase AC 220V, 50

Hz, optional power supply: AC220~660V, 50.60Hz (needs to be explained during ordering).

2. Ambient temperature: -20~+60℃;optional temperature:-40~70℃.

3. Relative humidity: Not greater than 95% (at 25 ℃).

4. Working environment: The common type is used in the places without inflammable, explosive

and strong corrosive medium; the using environment of flame-proof products (ExdIIBT4) are

used in explosive gas mixture of IIA, IIB grades, T1-T4 groups.

5. Protective grade: IP65/67 (IP 68 for special ordering).

6. Working provisions for the motor: Rated operation time is 10min. Grade F insulation.

7. Anti-corrosive coating: High-temperature stoving varnish.

Notes:“I” indicates the connection dimensions of power station type product.

The parameters are used for common supplying, if you have special demands, please state during ordering.

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.
