Electric gate valve knowledge-MZ941H-64C mine explosion-proof electric gate valve

MZ941H-64C mining explosion-proof electric gate valve is mainly used in coal mines, underground, and generally this kind of explosion-proof mine electric gate valve, with coal safety electric gate valve, mining explosion-proof electric gate power supply voltage 380V and 660V, this electric gate valve must have coal Ancillary ability to enter the mine.
Electric device features:
With mine license and coal safety certification, explosion-proof protection class is IP68. Suitable for flammable and explosive occasions, high safety factor, strong operating function, stable performance and so on. Explosion-proof products are dI and dIIBT4, dI is suitable for non-excavation face of coal mines, dIIBT4 is used in factories, and it is suitable for explosive gas mixtures with environment of IIA and IIB T1-T4.
The performance of this product complies with the regulations of JB/T8528-1997. The explosion-proof performance meets the requirements of GB3836.1-2000 and JB/T8529-1997. And certified by the national explosion-proof electrical product testing center, obtained the explosion-proof certificate. Integral type electric equipment is derived from Z common type, adding a lot of electrical and electronic components, the overall general type of electrical part is mainly composed of multi-function module MK1 remote control module MK2 button box indicator, opening table, contactor Etc. The multi-function module MK1 is composed of a phase identifier XS, a contactor interlock protector HB and a DC power supply DC. The remote module MK2 consists of four solid state relays and three dial switches. The overall regulation type of electrical part consists of the regulation module TMK, explosion-proof mine electric gate valve, coal-electric gate valve, explosion-proof mine electric gate valve, mining explosion-proof electric gate valve, MZ941H-64C is mainly used in coal mines, downhole, and generally this type of explosion-proof mine Electric gate valve, with coal safety electric gate valve, mine explosion-proof electric gate power supply voltage 380V and 660V, this electric gate valve must be with coal security permit 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 to 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 scene / remote control conversion button, the left side of the site off the valve button, the right side of the site to open the valve button, cover the button box for the remote control, open the lid for on-site operation.
2. Mine electric gate valve, mining explosion-proof electric gate valve, MZ941H electric gate valve features:
1 The valve adopts pressure self-tightening seal or valve body and bonnet gasket sealing structure, which is reliable! Safe and reliable use.
2 The flap adopts the middle top structure of the double gate plate, which can automatically adjust the valve flap and the sealing surface of the valve seat to ensure the sealing of the valve. At the same time, the structure is easy to maintain, saves money, and the valve flap is interchangeable.
3 Valve flap and seat sealing surface Cobalt-chromium-tungsten cemented carbide is formed by plasma spray welding. The sealing surface has high hardness, abrasion resistance, abrasion resistance and long service life.
4 Valve stem made of nitrided steel, surface nitrided, high hardness, scratch resistance, corrosion resistance, long service life.
5 The electric device is equipped with a torque control mechanism, an on-site operating mechanism, a hand, and an electric switching mechanism. In addition to local operation, remote operation, PLC control, 4~20mA current input and output intelligent control, etc. can also be performed. 6 The manual valve is opened by a manual mechanism or a hand wheel at the time of impact. Reduce valve operating force.
7 The valve can be installed anywhere on the pipe while selecting the carbon steel or alloy steel valve according to the temperature of the medium and the medium.
8 When installing and commissioning the system for the first time, the valve must be opened to approximately half the position manually to prevent damage to the valve or electrical device due to phase reversal of the motor.
