QC series part-turn electric valve actuators
QC series part-turn electric valve actuators is another new product developed with high efficiency, low sound level, small size, light weight, long service life. In the control room operator can control the distance of the valve can also be manually operated in the field can also be achieved with a computer and computer automatic control. The series of electric valve actuators are widely used in petroleum, chemical, water, electricity, metallurgy, shipbuilding, light industry, food industry. For small and medium-caliber ball valve, plug valves, etc. for part-turn valves and similar devices. The Protection-grade of these products is IP54(IP67 for special order). All of the technical data for these products are in accordance with the standard GB/T24923-2010<
Dimensions of driving elements and transmitted torque
1 In order to ensure that there is no interference between the driving part and the driven part in the driving device, the length of the driven part above the joint surface must be limited Degrees, so that there is a certain distance between them. . 2 Key connected driver 2.1 The dimensions of the drive elements connected by keys shall comply with the requirements of Figure 3 and Table 4. . 2.2 d, h in Table 4; The values of and l: are determined in the form of a single key with the diameter of the driving element (shaft) less than or equal to 98 mm. Use two and two The dimensions in Table 4 are still applicable when more than keys transmit torque. 2.3 The size of keys shall comply with the requirements of GB/T 1095. . 2.4 The keyway of the drive shall be in accordance with the position specified in Figure 7 or Figure 8 in 8.1 of this standard.
KQC, HKQ series electric device for partial rotary emergency shut-off valve
KQC and HKQ series electric devices for emergency cut-off valves are electric devices for driving and controlling the quick opening and closing of partial rotary valves. The opening and closing time can be selected as 2~15s. It is applicable to ball valve, butterfly valve, damper and other similar equipment. The operator can control the valve remotely in the control room, manually in the field, or automatically with the computer. This product is widely used in petroleum, chemical industry, hydropower, metallurgy, shipbuilding, light industry, food and other industrial sectors. The protection grade of the product is IP54 (IP67 for special orders), and all technical performances of the product comply with the provisions of GB/T24923-2010 Technical Conditions for Electric Devices of General Valves. The explosion-proof product (model includes B) has an explosion-proof grade of ExdIIBT4, and a protection grade of IP54 (IP67 can be reached for special orders). All technical performances of the product comply with the provisions of GB/T24922-2010 Technical Conditions for Electric Devices of Flameproof Valves. According to the special requirements of customers, the company also provides adjustable, electromechanical, AC, DC 220V and other electric devices with different frequency power supplies. The valve opening and closing angle can be 45, 110, 180 and other angles.
Position of driven parts
8.1 Key connection driver When the valve is in the closed position, the key should be in the position shown in Figure 7 or Figure 8. The standard closing direction is clockwise when viewed from up to down of the joint face Hour. If more than two keys are required, their positions shall be determined by negotiation between the supplier and the purchaser. 8.2 Parallel or diagonal square drive When the valve is in the closed position, the parallel square head and diagonal square head positions of the driven part shall conform to the positions shown in Figure 9 or Figure 10. 8.3 Flat head drive When the valve is in the closed position, the flat head of the driven part shall conform to the position shown in Figure 11.
