The electric gate valves, explosion-proof electric gate valves, and explosion-proof electric gate valves produced by RTV Ruitong Valve are simply controlled by electric actuators to achieve the opening and closing of valves. It can be divided into two parts: the upper part is an electric actuator, and the lower part is a valve with a greater action force than an electric valve. The opening and closing speed of the electric valve can be adjusted, and the structure is simple and easy to maintain. During the action process, due to the buffering characteristics of the gas itself, it is not easy to be damaged due to jamming, but there must be a gas source, and its control system is also more complex than that of an electric valve. Electric gate valves have sensitive response and are safe and reliable.
The MZ941H series mining electric gate valve is easy to install, easy to debug, and does not require maintenance for several years after debugging. When used in conjunction with KXBC-3 × 15/660 (380) DZ or KXBC-15/660 (380) DZ, the mining explosion-proof electric device can be connected to the DCS system. The explosion-proof protection level of the mining explosion-proof electric gate valve is IP68, and it is one of the few enterprises that has the mining coal safety certificate and explosion-proof certificate. Mining explosion-proof electric gate valves are suitable for coal mining applications, with high safety factors, strong operating functions, and stable performance. There are two types of explosion-proof products, dI and dIIBT4, and dI is suitable for non mining working faces in coal mines; DIIBT4 is used in factories and is suitable for gas mixtures of Class IIA and IIB T1 to T4 environments.
