Z941H Mine electric gate valve design parameters:

The performance of Z941H explosion-proof electric gate valve for mining meets the requirements of JB/T8528-1997< Technical Conditions for Ordinary Valve Electric Device >. The performance of explosion-proof type conforms to the provisions of GB3836.1-2000< General requirements for explosion-proof electrical equipment for Explosive Environment > and JB/T8529-1997< Technical Conditions for Explosion-proof valve electric device >.

Z941H Mine electric gate valve Features:

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

② The valve disc adopts a double gate with a universal top structure, which can automatically adjust the compatibility between the valve disc and the sealing surface of the seat to ensure the sealing of the valve. At the same time, the structure is convenient for maintenance, cost saving, and the valve disc interchangeability is good.

③ The sealing surface of the valve disc and seat is made of cobalt-chromium-tungsten carbide by plasma spray welding. The sealing surface has high hardness, friction resistance, abrasion resistance and long service life.④ Valve stem made of nitriding steel, surface nitriding treatment, high hardness, abrasion resistance, corrosion resistance, long service life.

⑤ The electric device is equipped with torque control mechanism, field operation mechanism and hand, electric switching mechanism. In addition to local operation, it can also carry out remote operation, PLC control, 4~20mA current input and output intelligent control.

⑥ The manual valve is opened by the manual mechanism or the hand wheel on impact. Reduce valve operating force.

The valve can be installed in any position of the pipeline, and carbon steel or alloy steel valves can be selected according to the temperature of the medium and the medium.

When installing and debugging for the first time, the valve must be opened manually to about half of the position, so as not to cause valve or electrical damage due to the reverse phase sequence of the motor.

Z941H Mine electric gate valve Features:

1. The device is dustproof, waterproof and light corrosion resistant, and its protection grade is IP55,IP65 (special order);

2. Torque control mechanism reliable action, easy adjustment, high torque repetition accuracy;

3. The adjustment accuracy and repetition of the stroke control mechanism are high, and the opening direction and the closing direction can be equipped with 2 to 4 microswitches each;

4. Semi-automatic hand-electric switching mechanism, simple mechanism, reliable work, light operation;

5. Working environment: no flammable, explosive and strong corrosive media.

Z941H mine explosion-proof electric gate valve is suitable for flammable and explosive occasions, with high safety factor, strong operation function and stable performance. Explosion-proof products are dI and dIIBT4 two kinds, dI is suitable for coal mine non-mining face; dIIBT4 is used in factories and is suitable for explosive gas mixtures in IIA and IIB groups T1 to T4.

Z941H Mine electric gate valve application conditions:

Widely used in building materials, metallurgy, chemical, electrical and other industries, as a compression explosive pipe pressure relief device. It is especially suitable for coal grinding system and storage of flammable and explosive gas materials. The valve is simple in structure and consists of a steel welded cylinder and an explosion-proof valve plate. When the system pressure is greater than 0.1Mpa gauge pressure, the explosion-proof valve plate breaks itself to prevent the system from exploding, so as to ensure personal and production safety.
