Once pile-up valve 42 or the second lower pile-up valve 12 include the first drain valve 14 for steam condensate (SC) to be discharged, and carry out step 2.
Steam valve 13 is opened when with step 4. and the first drain valve 14, high-temperature steam provide heat and in the process shape for foaming
At condensed water, it is V1 that steam condensate (SC), which forms speed, and the drainage speed of the first drain valve 14 is V2, and V2 is no more than V1 first
Fluid-tight face is formed between drain valve 14 and lower chamber, the fluid-tight face can stop high-temperature steam that pile-up valve is discharged.
As viewed in figures 5-8, the described first lower pile-up valve 12 or the second lower pile-up valve 42 include Main Control Tank 15 and the first draining
Valve 14, the Main Control Tank 15 include first chamber 151 and second chamber 152, and the first chamber 151 passes through water inlet air intake 154
It is connect with lower chamber (not shown), the second chamber 152 is equipped with draining steam drain 155.First drain valve 14 is located at master
It controls on case 15, and the first drain valve 14 connection first chamber 151 and second chamber 152, the water inlet of first drain valve 14
141 are connected to and the first water outlet 142 is connected to second chamber 152 with first chamber 151.
Mold first opens the first drain valve 14 before foaming, due to only opening the first drain valve 14, or less gas
Indoor steam can only be discharged into the first drain valve 14 after entering first chamber 151 by water inlet 141, and steam is pre- in foaming process
Cold formation condensed water, condensed water flows into second chamber 152 from the first water outlet 142, finally from the draining steam discharge of second chamber 152
Lower pile-up valve is discharged in mouth 155.In entire drainage procedure, it is V1 that the steam condensate (SC) in the first drain valve 14, which forms speed, the
The drainage speed of one drain valve 2 is V2, and V2 is not more than V1, and such condensed water can not disposably be discharged, so steam condensate (SC) can
With gradually accumulation accumulates to form fluid-tight face between the first drain valve 14 and lower chamber, the fluid-tight face can block the first drain valve
14, so that condensation water energy continues outward slowly discharge, but most of high-temperature steam is retained in type chamber 5 because being condensed water resistance gear
It is interior, it realizes only draining and does not arrange steam or arrange steam less, prevent high-temperature steam to be discharged, saved steam resource, improve hair
Steep efficiency.
Preferably, the reservoir 143 being connected to the first water outlet 142, the storage are equipped with inside first drain valve 14
Pond 143 is located between water inlet 141 and the first water outlet 142.The reservoir 143 can be used for putting aside condensed water, because steaming
The speed V2 that vapour condensed water is discharged inside the first drain valve 14 is slower than the speed V1 of steam condensate (SC) formation, undischarged condensation
Water savings forms fluid-tight face in reservoir 143, stops high-temperature steam discharge.
Preferably, the first water outlet 142 of first drain valve 14 is located at the side wall of second chamber 152, and bore ruler
It is very little within 1 cun.
Preferably, the described first lower pile-up valve 12 or the second lower pile-up valve 42 further include for steam condensate (SC) to be discharged
The water inlet of two drain valves 16, second drain valve 16 is connected to first chamber 151 and the second water outlet 161 connects with second chamber
Logical 152.When second drain valve 16 is opened, steam condensate (SC) can drain into second from the second water outlet 161 of first chamber 151
Chamber 152, then lower pile-up valve is discharged from draining steam drain 155.But the drainage speed V3 of the second drain valve 16 is faster than condensed water
Speed V1 is formed, is discharged together so having part high-temperature steam in drainage procedure.When carrying out step 6., the second draining is used
Valve 16 can reach the purpose of Quick drainage.
Preferably, this pile-up valve 41 further includes for being blown into room temperature gas in gas chamber on pile-up valve 11 and second on first
