4, floating ball for stainless steel bracket, use fixed number of year of the survival of long, safe and reliable. Such as water pumps, any time will initiation of negative pressure and floating ball any time loss, execute number inhale to ensure road safety. Semi-automatic exhaust valve 1 main technical parameter and performance indicators. Medium: water 2. Temperature: room temperature. 3. Body: grey iron HT2004. Floating ball and stopper: stainless steel 5. Tightly closed material: nitrile butadiene rubber (6). Body trying to fight suppression: 1. 5mpa　　7. Floating ball and tightly closed trying to blow to neutralize: 0. 05 - 1. 1 mpa not leaking. for round barrel body, a total of neri are mainly stainless steel ball float and head. 3, exhaust has experience is more than the usual double orifice discharge valve. Po this valve installed in the pump outlet or send water distribution pipeline, to number out of the pipeline volume of air, so as to promote the pipe and pump use rate, and tube once revealed negative pressure, the valve can rapidly-changing inhaled air, initiation damage by negative pressure to hold the line. Semi-automatic exhaust valve main unique place 1, able to dispense with pipeline in gas, material loss resistance to save energy. 2, when the pipeline pressure, this product can quickly semi-automatic suction air to avoid cracks. Q: the main Marine valves use a: semi-automatic exhaust Industrial Valves pipe during operation, the floating ball in the ball at the bottom of the bowl, quantity of exhaust, when the tube air, water rushed into the valve, through the ball float bowl and then reaction, to close the floating ball float, pipeline during normal operation, if there is a small gas experience grasp on to reasonably in the valve, the valve in the inland waters scalar potential loss, floating ball waned, gas QiXiaoEr hole eduction. Semi-automatic exhaust valve main use: this valve is suitable for use in industrial medium for water piping, gas as quickly dispense with the pipe facilities, to increase the rate of water facilities and try our best to take care of pipelines from variant cracks, is the pipeline must have facilities. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
