| Self-pressure regulating valve is divided into self-pressure, differential pressure and flow control valve three series. Self-pressure regulating valve according to two minutes before the pressure tap position valve and the valve, the pressure tap at the front valve for regulating valve before the pressure constant; take pressure point in time after the valve for constant pressure after the valve . When the valve before and after the valve pressure on both sides of the chamber while introducing implementing agencies, self-pressure regulating valve can be adjusted constant pressure regulating valves at both ends, it can also be installed in the pressure differential across the orifice pipe introduced into the film execution both sides of the chamber body, composed of self-operated flow control valve, or the valve flow detection after adjusting for traffic with self-pressure in other ways. |
