Uses:
Safety valve is an automatic overpressure protection valves, as boilers, pressure vessels and pressure piping for safety accessories, widely used in many industries. Special equipment in accordance with national technical specifications "safety valve safety technology supervision order" requirement: check valve on a regular basis, usually at least once a year. Current petrochemical and chemical industry, some devices require continuous operation for one year or more, it is difficult to achieve parity once a year, some devices are continuous operation, the need to overhaul period. Above, if the safety valve on the device fails, it is difficult for non-stop for valve repair or replacement.
My company supply safety valve fast switching device is a compact, well-designed valve device. Discharge to meet users online backup capacity requirements, maintenance and calibration devices to solve production safety valve contradiction between the device without stopping to provide continuous overpressure protection device to extend the operation of the protected period.
