Gas special butterfly, WSD94F mine gas supplier Overview special butterfly valve with special gas mine: Widely used in coal mine gas drainage system piping, can meet mine gas under high explosive and highly corrosive media requirements for long-term safe operation Mine gas valve fully open, fully closed to within 15 seconds, the fastest time, so the safe operation of the gas extraction system is more reliable. And "KXB series flameproof electric valve actuators control box" supporting the use, can interface with the DCS system, fully automated production equipment to meet the coal demand. The company is particularly recommended: WSD-way gas pressure soft sealing butterfly mine, mine gas butterfly valve seals deformation compensation structure, so that the loss of part of the sealing pressure than compensated for, to ensure the valve in the role of the media in any direction, can achieve tight off, only one-way valve to solve the ordinary pressure, the reverse leakage defect easy; bi-pressure, two-way sealed, positive and negative in both directions can achieve zero leakage, especially for the need to double the flow of the sealing function of the complex piping systems. WSD94F dedicated mine gas valve has a simple structure, small size, light weight, material consumption province, small installation size, switch quickly, 90 ° reciprocating rotary drive torque characteristics of small, used to cut, turn, regulate pipeline medium, having good fluid sealing properties and off control characteristics. You can carry mud accumulation of fluid in the pipe mouth least. Under low pressure, can achieve a good seal. Regulation performance. Electric butterfly valve disc streamline design, so that the loss of fluid resistance, can be described as an energy-saving products. Electric butterfly valve stem through-rod structure, after quenching, with good mechanical properties and corrosion resistance, scratch resistance. Electric butterfly valve opening and closing the valve stem when only rotational movement without making lifting operation, the valve stem packing is not easy to destroy, reliable sealing. And disc taper pin fixed, extended end to prevent out design, in order to avoid the stem and disc connected to the stem of the accident when the collapse of the fracture.
