Mining coal safety explosion-proof gas special electric gate valve

Mining coal safety explosion-proof gas special electric gate valveOperation method Product features:

　　① The valve adopts pressure self tightening sealing or valve body and valve cover gasket sealing structure, which is trustworthy! Safe and reliable use.

　　② The valve disc adopts a double gate plate with a universal top structure in the middle, which can automatically adjust the degree of fit between the valve disc and the sealing surface of the valve seat to ensure the sealing of the valve. At the same time, this structure is easy to maintain, saves costs, and has good interchangeability of valve discs.

　　③ The sealing surface of the valve disc and seat is made of cobalt chromium tungsten hard alloy by plasma spray welding. The sealing surface has high hardness, wear resistance, abrasion resistance, and long service life.

　　④ The valve stem is made of nitriding steel, with surface nitriding treatment, high hardness, scratch resistance, corrosion resistance, and long service life.

　　⑤ The electric device is equipped with a torque control mechanism, on-site operating mechanism, and manual/electric switching mechanism. In addition to on-site operation, remote operation, PLC control, and intelligent control of 4-20mA current input and output can also be performed.

　　⑥ Manual valves are opened by a manual mechanism or a handwheel upon impact. Reduce valve operating force.

　　⑦ Valves can be installed at any position in the pipeline, and carbon steel or alloy steel valves can be selected based on the medium and its temperature.

　　⑧ When installing and debugging for the first time, the valve must be manually opened to about half of the position to avoid damage to the valve or electrical components caused by reverse motor phase sequence connection.

Mining coal safety explosion-proof gas special electric gate valve Product Technical Parameters

Explosion proof electric gate valve is a valve body equipped with a multi turn electric actuator, which enables the valve plate to move up and down in a straight line, realizing remote control of valve position switch, which is convenient and fast. Applicable to nominal pressurePN1.6～16.0MPa, Remote control valve position switches are implemented on the pipelines of various systems in petroleum, chemical, hydraulic, and thermal power plants with working temperatures ranging from -29 ℃ to 500 ℃, to cut off or connect pipeline media. Suitable for flammable and explosive environments, with high safety factor, strong operational function, and stable performance.

Explosion proof products includeThere are two types: dI and dIIBT4. dI is suitable for non mining working faces in coal mines; DIIBT4 is used in factories and is suitable for explosive gas mixtures in environments of IIA and IIB levels T1 to T4. The electric explosion-proof gate valve is suitable for explosive gas mixtures in environments of IIA and IIB levels T1 to T4.

　DN200 explosion-proof electric gate valve MZ941H-16C/25C DN150 mining integrated electric gate valve, mining explosion-proof electric gate valve, MZ941H-16C, MZB941H-100C mining coal safety certificate, explosion-proof electric gate valve, MA coal safety electric gate valve is mainly used in coal mines and underground. Generally, this explosion-proof mining electric gate valve is equipped with a coal safety electric gate valve. The power supply voltage of the mining explosion-proof electric gate valve is 380V and 660V. This type of electric gate valve must have a coal safety certificate before entering the mine.
