Q: according to the actual working condition of the steam trap selection using a: 1. Based on actual use conditions to confirm the inlet and outlet of steam trap differential pressure. Steam inlet pressure of the steam trap refers to the flap for steam pressure or temperature regulating valve throttle, steam trap at the entrance to the lowest pressure office; Outlet pressure of the steam trap is refers to the steam trap has supreme office to emerge from the back pressure, when the atmosphere, the actual pressure differential in accordance with the steam inlet pressure trap vote. 3. Frozen water can use the following method for calculating: ( 1) Initiation of coagulation water pipeline runtime q = q0l ( 1 - Z/one hundred percent) ( kg/h) , this formula: q: frozen water ( kg/h) Q0: light tube initiation of frozen water ( kg/h) L: the distance between the point of hydrophobic ( m) Z: heat preservation rate ( One hundred percent) ( 2) Steam heating facilities runtime initiation of coagulation water q = VRC delta t/ht Marine valve, this formula: q: frozen water ( kg/h) V: the size of the heated object ( m3) R: heated objects (in terms of kg/m3) C: the specific heat of liquid ( kcal/kg. oc) Delta t: liquid body temperature rises ( oc) H: steam latent heat ( 千卡/公斤) T: heating time 4. Each product type steam trap structure and the principle is different, is not the same performance liquid, can according to the use of different occasions when choose, choose different steam trap. 2. Based on steam heating facilities in the normal office during initiation of frozen water, multiplied by the correction coefficient k, and then execute selected in accordance with the displacement of the steam trap. 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.
