a lot of customers in the process of purchasing exhaust valve, don't know the compound options for exhaust valve. The valve is to introduce the down today?

high was the point in the pipeline, we respectively calculate the largest exhaust ( Or inspiratory capacity) 。 A, as calculated by the water pump to send: ( Suction) The vent valve C. F。 S =泵的流量/ 449 ( Inch) Or CMH of PUMP ( The metric system) B, such as: (by gravity flow calculation Suction) The vent valve C. F。 S = 0。 08666 ( SD5) 1/2 ( Inch) 不啻= 8。 83 ( SD5) 1/2 ( The metric system) D = S = slope pipeline diameter 2, if considering the maximum displacement, general composite exhaust Industrial Valves ( CARX) The inlet pressure psi (4 0. 028MPa) When the air pipe can be in, the plug head will finish tube air, from 1 a or 1 b to calculate the maximum displacement and 4 of the psi as the reference point, the performance curve table lookup, can get the appropriate CARX caliber. Three, if considering maximal inspiratory capacity, general tube negative pressure generated and more than 5 psi ( 0. 03MPa) Above can be broken tube, at that point can be calculated from 1 a or 1 b of maximal inspiratory capacity and 5 psi as reference point, the performance curves of look-up table, can get the appropriate CARX caliber. Four, by comparison, 2 and 3 of large caliber, is the calibre of we need. Five, if don't consider caused by negative pressure produced pipe burst, can be directly used in the following table to choose appropriate CARX caliber, water velocity and pipe in 1. 2 - 2. 4 m/SEC, also can use the table below to choose CARX caliber.
