江苏兰 valve General Equipment Co., Ltd. of KXBC series flameproof electric valve control box structure design Open the door actuators role, with the DCS system interface functions converge in the electrical properties of the design. Mine Explosion basic valve control box Technical parameters: 1. Power supply voltage: 660 (380) V 2. Control Voltage: AC36V, AC24V; DC24V 3. Rated current: 9-15A 4. Rated frequency: 50Hz 5. flameproof, explosion-proof mark ExdI Mb Jiangsu Lan valve General Equipment Co., Ltd. with coal safety certificate valve control box explosion-proof products are two kinds of dI and dIIBT4 actuators, dI applicable to non-coal mining face; dIIBT4 for factory valve actuators for the environment IIA, IIB grade T1 gas mixture ~ T4 group. Explosion Point 1) control box requires proof of an explosive mixture inside the cavity when the explosion, flameproof enclosure is not damaged and can not guarantee the internal flame control box casing joints caused by an explosion outside an explosive mixture. 2) The component parts of the flameproof enclosure, after finishing have been GB3836.2-2010 provisions 1.0MPa, which lasted no less than 10S hydrostatic test pass, in order to ensure maximum internal explosion can withstand pressure without damage. 3) The number of bolts fastening connection flameproof enclosure indispensable bolt screwed into the depth of 1.2 to 1.5 times the diameter to withstand the explosion pressure. Each bolt and nut spring washers under both the actuator structure to prevent self-loosening. 4) control box of the box, cover, junction box cover, transparent parts, terminals, cables are proof seals and other parts, which must not bump proof surface, without scratches and other defects affect the explosion effect. 5) junction box inlet and outlet has rings (see Figure 3), which the cable outer diameter to be consistent with the smallest ring diameter, in order to ensure that after the press-fit compression nut, so between the seal and the seals and the cable and wiring no gap between the cartridge body, or can not flameproof. Butterfly valve actuators, actuators, valve provided by 江苏兰 江苏兰 valve General Equipment Co.江苏兰 valve General Equipment Co., Ltd. (www.lanfa.cn) strong, credible, in Changzhou, Jiangsu regulating valve industry has accumulated a large number of loyal customers.
