Overview

The intrinsically safe automatic valve designed for explosive gas environments such as mining and metal mines, with its core design complying with the national explosion-proof standard GB 3836.4, ensures that the electric sparks or thermal effects generated under normal or fault conditions are not sufficient to ignite explosive gases.

Product Details

1Mining intrinsically safe electric ball valveProduct Introduction

The essential safety automatic valve designed specifically for explosive gas environments such as coal mines and metal mines, with its core design meeting the requirements of the national explosion-proof standard GB 3836.4, ensures that the electric sparks or thermal effects generated under normal or fault conditions are not sufficient to ignite explosive gases. ‌

　　Mining intrinsically safe electric ball valveIt is a core feature

Intrinsic safety design: By limiting parameters such as circuit voltage (≤ 12V DC) and current (≤ 100mA), and using safety barriers (such as Zener or isolated), the risk of energy transfer is further reduced. ‌

Remote control: driven by DC 12V/24V low-voltage power supply, supporting switch control (such as 24V DC signal) and analog adjustment (4-20mA), suitable for automation system requirements. ‌

Lightweight and low-power: Compared to explosion-proof equipment, it is lighter and consumes less energy, making it suitable for underground distributed control scenarios. ‌

Technical Specifications

Execution mechanism: Supports IP65 protection level and adapts to humid underground environments; Torque range 10-200N · m, suitable for DN15-DN100 caliber valves. ‌

Material: The valve body is mostly made of aluminum alloy or stainless steel (304/316L), with anti-corrosion treatment on the inner wall; The seal is made of PTFE, EPDM and other materials, suitable for normal temperature and low pressure working conditions. ‌1

Application scenarios

It is mainly used in the automatic system of underground pump room in coal mine, automatic spray dust control device and other scenarios, and can realize automatic control of local ventilation, drainage or grouting valves. ‌

This type of product needs to pass the National Safety Standards Center (MA certification), and the explosion-proof level is usually Ex ib I Mb (Class I coal mine intrinsic safety type).
