Overview of Z941H Mine Electric Gate Valve:
The Z941H explosion-proof electric gate valve for mining is suitable for flammable and explosive environments, featuring high safety factors, strong operational functions, and stable performance. Explosion-proof models include dI and dIIBT4 types, with dI designed for non-mining areas in coal mines; dIIBT4 is used in factories and suitable for environments with IIA, IIB class T1～T4 explosive gas groups.
Design Parameters of Z941H Mining Electric Gate Valve:
The performance of the Z941H explosion-proof electric gate valve meets the requirements of JB/T8528-1997 <Technical Conditions for Electric Devices of General Valves> and the explosion-proof model conforms to the specifications of GB3836.1-2000 <General Requirements for Explosion-Proof Electrical Equipment Used in Explosive Environments> and JB/T8529-1997 <Technical Conditions for Explosion-Proof Electric Devices of Cut-off Valves>.
Features of Z941H Mine Electric Gate Valve:
① Valves feature pressure self-tightening seals or a sealing structure with valve body and cover gaskets, trusted for reliability! Safe and dependable in use.
② The valve disc features a double gate plate with a universal top structure, which can automatically adjust the fit between the valve disc and seat sealing surface, ensuring the valve's sealing. Additionally, this structure is easy to maintain, cost-effective, and offers good interchangeability of valve discs.
③The valve seats and sealing surfaces are made of cobalt-chromium-wolfram hard alloy plasma spray-welded, featuring high hardness, wear resistance, scratch resistance, and a long service life.
④ The valve rod is made of nitriding steel, with a surface nitriding treatment, featuring high hardness, excellent wear resistance, corrosion resistance, and a long service life.
Unit is equipped with torque control mechanism, local operation mechanism, hand/electric switching mechanism. In addition to local operation, it also supports remote operation, PLC control, and intelligent control with 4~20mA current input/output.
⑥ Manual valves are opened by a manual mechanism or by handwheel impact. Reduces the operating force of the valve.
Valves can be installed at any location on the pipeline, and carbon steel or alloy steel valves should be chosen based on the medium and its temperature.
⑧During initial installation and tuning, the valve must be manually opened to about half its position to prevent damage to the valve or electrical installation due to reversed motor phase sequence.
Z941H Mine Electric Gate Valve Application Conditions:
Broadly applicable to industries such as building materials, metallurgy, chemicals, and electrical engineering, serving as a pressure relief device for compressed explosive pipelines. Particularly suited for coal grinding systems and warehouses storing flammable and explosive gases. The valve features a simple structure, consisting of a steel-welded cylinder and a blast-proof valve plate. When the system pressure exceeds 0.1 MPa gauge pressure, the blast-proof valve plate automatically bursts to prevent system explosion, ensuring personal and production safety.
