Detailed description of the invention
Fig. 1 is the first embodiment schematic diagram of ethylene oxide sterilizing heating system of the present utility model, as shown in the figure, comprise: expansion drum 11, it is connected with threeway 12 and depurator 13, described threeway 12 connects ball valve 14 and pressure switch 15, described depurator 13 connects automatic blow off valve valve air relief 16 and elbow 17, and described elbow 17 connects sterilization container water inlet of hot water 20 by ball valve 19, and described ball valve 14 connects water source.Described pressure switch 15, for when source pressure is lower than pressure switch setting value, sends " hydraulic pressure is low " alarm signal to ethylene oxide sterilizing system.
Described expansion drum 11 is primarily of compositions such as tank body, barrier film, automatic stop valve, aerating/steam vents.Be full of nitrogen or air extremely certain design pressure inside barrier film, nitrogen or air are filled with barrier film inside by aerating/steam vent.Expansion valve is as AMTROL FILL-TROL Italy company 112 type equipment.
When expansion drum 11 works, tap water enters heating system pipeline by expansion drum 11 pipeline, when the gas pressure of filling inside barrier film is greater than heating system pipeline pressure, automatic stop valve is opened, tap water is injected into heating system pipeline, when heating system pipeline pressure reaches the gas pressure of filling inside barrier film, automatic stop valve is closed automatically, stops toward the moisturizing of heating system pipeline.
Water volume 4 DEG C time is minimum, along with temperature ascending water volume also can increase naturally during heating, pressure can rise, and the not change of the total amount of water, hydrone needs to occupy more space, the gas be pre-charged with inside barrier film is compressed, the part that heat supply pipeline water volume increases due to heating enters inside storage tank, the pressure oscillation of expansion drum 11 adjustment heating system pipeline, avoiding heating system pipeline at full water can raise rapidly with water pressure when heating when isolated from atmosphere and cause the blast of heat supply pipeline or sterilization container outer wall water jacket.When heating system pipeline pressure reduces, due to temperature raise volume increase enter water inside storage tank can in barrier film blanketing gas promotion under again enter pipeline.
Because the water added in heating system pipeline is all dissolved with certain air usually, and the dissolubility of air reduces along with the rising of temperature, such water gas in the process of circulation is separated gradually from water, and the bubble even gas column that formation of slowly getting together is large.
In addition, when heating system pipeline pressure reduces, expansion drum 11 can supplement fresh water to heating system pipeline from the external world, so pipeline interior edema often has gas to produce when heating.When gas is by depurator 13, enter the top that automatic blow off valve valve air relief 16 valve pocket is gathered in vent valve, along with increasing of gas in valve, pressure increase, the air vent of automatic blow off valve valve air relief 16 can be opened; After gas drains, exhaust close.Same reason, when producing negative pressure in system, Exhaust Open, air can enter heating system pipeline by air vent.
Preferably, also comprise: threeway 21, described threeway 21 connection safety valve 22, described relief valve 22 connects discharge outlet 9.Described relief valve 22 is for when heating system pipeline pressure is higher than safety valve setting value, and the water in system pipeline is let out except arriving discharge outlet.
Preferably, connecting bend 23 is gone back in described threeway 21, and described elbow 23 adpting flange 25, described flange 25 connects electrical heating tank 26.Described electrical heating tank 26 is to the intensification of its internal water, insulation and firing equipment.Electrical heating tank is WARREN ELECTRIC CORPORATION company firing equipment such as.
Preferably, described electrical heating tank 26 connects temperature switch 28.Described temperature switch 28 is when the setting value of electrical heating tank 26 interior edema temperature higher than temperature switch, and the contact of temperature switch 28 disconnects, and electrical heating tank 26 stops heating.
Preferably, described temperature switch 28 adpting flange 27.
Preferably, described electrical heating tank 26 passes through flange 31 connecting tee 32, described threeway 32 connecting T-shaped thermocouple 33 and elbow 34.Described T-shaped thermocouple 33 ensures that by detecting hot water backwater terminal temperature the intensification of sterilization container internal gas, insulation and the rate of heat addition and effect are in optimum state.
Preferably, described elbow 34 connecting tee 35, described threeway 35 Bonding pressure table 36.Heating system pipeline hydraulic pressure measured by described Pressure gauge 36.
Preferably, described threeway 35 also connects water circulating pump 38, and described water circulating pump 38 makes the generation of heating system Pipeline Water circulate.
Preferably, described water circulating pump 38 connects sterilization container hot water backwater mouth 40.
