。 2. Exhaust valve diameter selection because traces of exhaust valve is suitable for use scope is small, can use directly, average diameter of 3/4 ', DN25; Because of complex Marine exhaust valve is a valve type trace exhaust valve and high-speed exhaust/air suction valve combination, because this compound exhaust valve with high speed exhaust/air suction Industrial Valves diameter selection of standard is the same 3. According to the performance curves of selection for high speed air exhaust/suction valve for water filling out and emptying inspiratory, because this should be comprehensive thinking problem in the pipe when the water filling out the empty mind ( Row of mind) And drainage vent pipe or tube try our best to take care of when inhaling empty mind ( Absorption of mind) , to calculate the water filling the outlet diameter, and calculating the emptying of inspiratory mouth diameter, the inside the larger diameter were selected as the exhaust gas/air suction valve diameter. Q: the classification of the exhaust valve selection a: 1. Of exhaust valve type selection project default should be based on specific things present situation to choose the type of exhaust valve, for some great point compound exhaust valve installation; For long-distance level decreased section, long distances without fold point section should install composite exhaust valve or trace exhaust valve; Decreased for slope becomes bigger, go up slope small point appropriate chooses trace exhaust valve; When demand vacuum try our best to take care of, should choose a combined exhaust valve; For long distances without fold point rise section can choose compound exhaust valve. 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.
