for mining is equipped with coal safety electric gate valve. The power supply voltage of the mining explosion-proof electric gate valve is 380V and 660V. This electric gate valve must have a coal safety certificate to enter the mine. Features of the electric device: It has a mine certificate and a coal safety certificate, and the explosion-proof protection level is IP68. It is suitable for flammable and explosive occasions, with high safety factor, strong operation function, and stable performance. There are two types of explosion-proof products, dI and dIIBT4. dI is suitable for non-excavation working faces of coal mines; dIIBT4 is used in factories and is suitable for explosive gas mixtures of IIA and IIB grades T1 to T4. The performance of this product meets the requirements of GB3836.1-2000 and JB/T8529-1997. It has been verified by the National Explosion-proof Electrical Products Testing Center and obtained the explosion-proof certificate. The integral type Denso is derived from the Z ordinary type, adding a lot of electrical and electronic components. The overall ordinary type electrical part is mainly composed of the multifunctional module MK1 remote control module MK2 button box indicator light, opening meter, contactor And other composition. The multifunctional module MK1 is composed of three parts: phase recognizer XS, contactor interlock protector HB and direct current power supply DC. The remote module MK2 is composed of four solid state relays and three DIP switches. Explosion-proof mine electric gate valve, with coal safety electric gate valve, mine explosion-proof electric gate valve, MZ941H-40C, MZB941H-40C coal mine electric gate valve, explosion-proof electric gate valve is mainly used in coal mines, underground, generally this kind of explosion-proof mine electric gate valve, with Coal safety electric gate valve, mine explosion-proof electric gate valve power supply voltage has 380V and 660V, this kind of electric gate valve must have coal safety certificate to enter the mine contactor and other components. The control line is 220V, 50Hz (special order 60Hz); remote control is 24VDC. The adjustment module can receive and output 4-20ma standard signals. The electrical components are mounted on a reversible board to adjust the torque control, stroke controller, and opening mechanism. There are three buttons on the button box, the middle is the field/remote control switch button, the left side is the field valve button, and the right side is the field valve opening button, the button box is closed for remote control, and the lid is opened for on-site operation. DZ-B explosion-proof multi-turn electric actuator, protection grade is ExDII BT4, suitable for operating gate valves, globe valves and other valves, protection grade IP65, output torque range: 50-80000Nm, output speed range: 0.5-5rpm, It is widely used in pipelines for gas or coal mines. It is used on the mining surface and has stable quality and good explosion-proof performance. The products are also superimposed on intelligent integrated explosion-proof and integrated explosion-proof. Our company has produced explosion-proof voltages of three-phase 660V, 415V , 380V, two-phase 220V, product appearance, quality, has been repeatedly praised by users! DZW5-1000 Introduction Explosion-proof valve electric device, used in coal mines or flammable and explosive occasions, brings safety and convenience to yourself and others, and causes unnecessary losses. According to the use environment: ZW is outdoor type; ZB is explosion-proof type; ZZ is integral type; ZT is integral adjustment type. The performance of this product meets the requirements of JB/T8528-1997. The performance of the explosion-proof type meets the requirements of GB3836.1-2000 and JB/T8529-1997. It has been verified by the National Explosion-proof Electrical Products Testing Center and obtained the explosion-proof certificate. Installation method and precautions The device can be installed vertically and horizontally, but the motor cannot be downwards. It should be convenient for wiring, debugging and manual operation. Different power supplies are not allowed to be applied to the normally open and normally closed contacts of the same micro switch. The axial clearance of the jaws connected to the valve is not less than 1-2mm. Check whether the grounding is reliable before powering on. When the newly installed electric device is electric for the first time, the phase sequence of the motor must be checked and the control circuit is correct to prevent the motor from losing control.
