The working order of this water boiler is as follows:
When unlatching forces water intaking valve (25) to add water in container (15), water borrow source pressure from water source tube (27) and pressure water inlet pipe (7) to container (15) inner water-supply, gas in the container (15) judges that by trunk line (16) and flow velocity check (non-return) valve (1) enters cold water storage cistern (2) when flow is suitable, in container (15), be full of water, close and force water intaking valve (25) heating of can switching on, electrothermal piece (9) is passed to water with heat, water temperature constantly raises, at this moment dissolved gases is constantly separated out in the water, the volume of water also constantly increases, they constantly flow into cold water storage cistern by trunk line (16) and judgement check (non-return) valve (1), this moment, flow was very little, judged that check (non-return) valve (1) is in the reverse-conducting state.When water is heated to fluidized state, to there be a large amount of water vapours to produce, thereby make the rapid flow of fluid of trunk line (16), diaphragm (43) the compression spring (41) of judging check (non-return) valve is moved backward, diaphragm (43) develops with valve seat (40) end face, stop the outflow of water, vapour, when reverse pressure reduction, conducting once more.With the flow velocity judgement check (non-return) valve (38) of connected mode shown in Figure 2 and accompanying drawing 6, when valve body (46) was in no pressure reduction state, spool (47) fell by gravity when cold water storage cistern is in container (15) and goes up, and valve is in conducting state; When the low discharge fluid upwards flows, spool (47) is the state of waving, at this moment the tip of propping up pawl (49) because of spool withstands on the inwall of valve body (46) loosely, institute is so that spool (47) keeps the energy easy on and off to slide, make its circumferential backlash reduce to minimum degree again, spool (47) is though wave, but can not rise to the position of valve seat (48), thus vapour-liquid can pass through, when vapour-liquid amount of flow during greater than certain value, spool (47) is held up by vapour, and lean against on the valve seat (48), thereby make passage airtight, when reverse pressure reduction is arranged, spool (47) could sink, and is switched on once more.When judging that check (non-return) valve is in reverse blocking state, pressure in the container (15) just might raise, correspondingly saturated vapor pressure also raises gradually, at this moment by pressure measurement arm (5) pressure is passed to bellows (6), diaphragm (58) is moved backward and drive load sheet (56) and move, when the reaction force that overcomes spring (55) when it moved to certain position, switch (4) moved power remove, stops electrothermal piece being heated.The position that changes jackscrew (54) can change the prestressing force of spring (55) to load sheet (56), thereby can select different shutoff pressure, carries on the back female (53) trivial firmly jackscrew (54) after selecting to turn-off pressure.
After stopping heating, after pressure in the container (15) is kept a period of time, because heat radiation, pressure descends gradually, when pressure drops to a certain numerical value, spring (55) in bellows (6) promotes load sheet (56) and moves to certain position, switch (4) is connected once more, and electrothermal piece (9) is heated again, thereby the pressure in the container also raises once more, so go round and begin again, make the water in the container (15) keep boiling temperature.
When water intaking, when using the special valve body tap (1) shown in the accompanying drawing 9, push push rod (20) backward with the container that is filled with water, push rod drives axle (71), axle (71) pull-up depression bar (69), overcome the pressure of spring (68), make spool (67) lose pressure, therefore, hydraulic pressure in the container is pushed spool (67) open, the boiling water amount discharge container is after draining and steam discharge finish, even in time do not loosen push rod (20), if when not had pressure or being negative pressure in the container, spool (67) also can fall according to gravity and pressure automatically, makes valve seat (66) sealing, thereby prevents that air from entering.Magnet (21) is housed in the end of push rod, push rod (20) moves backward when water intaking, and it is close to tongue tube (22) to drive magnet (21), thereby makes tongue tube (22) conducting, so that when draining, connect circuit to keep the pressure in the container (15), guarantee smooth draining.
The also special valve body tap (81) of available another embodiment during draining, see accompanying drawing 10, when fetch water in the end of pushing push rod (75), the power that drive depression bar (77) overcomes spring (72) moves up, make diaphragm (65) lose pressure, because the pressure in the container (15) makes water back down diaphragm (65), flow out valve through exhalant canal (80) and depotition cock (76).If when presenting negative pressure in the container (15), diaphragm (65) is inhaled on the end face that is pressed in valve seat (64), thereby stop entering of air.In container (15) internal pressure during greater than a certain numerical value, the power on the diaphragm (65) of acting on is greater than the stress of spring (72), thereby can back down the sealing of diaphragm (65), the excess pressure in the discharging container (15).When push rod (75) when being pressed, depression bar moves on (77), depression bar (77) but the convex edge pull switch (78) of lower end is connected circuit, keep the pressure in the container (15), with smooth draining.Make the special valve body tap of this this embodiment directly use switch (78) to replace this tongue tube (22) without magnet steel conducting tongue tube (22), this switch is located on the position of tongue tube (22) on accompanying drawing 11 circuit.
When in container (15), taking a morsel water, magnetic float (17) is in tongue tube sleeve pipe (12) top by buoyancy of water and is subjected to stopping of baffle plate (14) to stay in sleeve pipe (12) end, because the effect of magnet steel (64), make tongue tube (13) closure, thereby the connection circuit is kept the pressure in the container (15).
When water withdrawal was big, the liquid level of boiling water descended, and magnetic float also descends with liquid level, disconnected in reed pipe (13), at this moment removed when water intaking promotes push rod (20), and magnet steel (21) makes tongue tube (22) closure; When perhaps using the special valve body tap of another embodiment of accompanying drawing 10, owing to move on the depression bar (77), pull switch (78) is connected circuit, to keep outside container (15) internal pressure, circuit no longer heats to container (15), subsequently because heat radiation, pressure in the container (15) descends gradually, land vertically to negative pressure, water in the cold water storage cistern (2) is because atmospheric pressure is pushed the diaphragm of judging check (non-return) valve (1) open, by trunk line (16) to container (15) inner water-supply, perhaps the situation that is in container (15) upper end at cold water storage cistern (2) when (as shown in Figure 2) cold water push flow velocity open and judge that the diaphragm of check (non-return) valve directly intakes from container (15) top.Along with entering of cold water, steam in the container is condensed, pressure further descends, impel water to quicken to enter, be full of once more until water, magnetic float (17) floats with liquid level, tongue tube (13) closure, circuit is connected, and container is begun heating again, and enters temperature control program.
Because the effect of container (15) external thermal insulation and the thermal capacitance of container, pressure is longer from the time that malleation is transformed into negative pressure, forms the fixed time period of certain limit, promptly forms time-delay automatic water supplement function.When boiling water is produced in the rapid moisturizing of needs, can press and force water intaking valve handle (24) to open pressure water intaking valve (25).Make cold water by source pressure by forcing water inlet pipe (7) to container (15) inner water-supply, can make container inner pressure be transformed into negative pressure state rapidly, and then intake from trunk line (16), or the flow velocity judgement check (non-return) valve that passes through accompanying drawing 2 is intake from container (15) top, like this, can enter into water program immediately, enter into and close pressure water intaking valve (25) again after the water program, water also can be mended full automatically.Because cold water is mended into container, the liquid level of cold water storage cistern (2) descends, and ball float (3) also descends thereupon, thereby ball-cock assembly (28) is opened, and original liquid level is kept in moisturizing in cold water storage cistern.Can pass through pressure-display device (18) expression to the pressure condition in the container (15), by this indication, the water intaking people should fetch water when malleation, and when low pressure or negative pressure, can fetch water, in order to avoid water blindly fetch water at a simmer the time and get less than, but to cold water storage cistern on container (15) top for example accompanying drawing 2 such types can at any time obtain water, what certainly take out during less than boiling point in water temperature is warm water.When being certain malleation in the container (15), captions diaphragm (37) pressurized is pressed on the ground glass sheet (36), thereby make the captions of this diaphragm (37) clearly have an X-rayed out, for example accompanying drawing 4 has an X-rayed out " please drink " two words like that, and when negative pressure, can't see this demonstration.
Accompanying drawing 11 is circuit diagrams of this water boiler, when switch (4) during with a certain reed switch conduction that is connected in parallel to each other (when using the special valve body tap of accompanying drawing 10, this tap (78) also can replace the tongue tube (22) in parallel with tongue tube (13)), coil gets, contact (62) closure can make electrothermal piece (9) energising, when the rising of the pressure in the container (15) is cut off switch (4), then contacts coil J dead electricity, contact (62) disconnects, and stops heating.When pressure decline, switch (4) is connected once more, and circuit begins to send electricity again, and container boosts, and carries out so repeatedly, finishes the function of keeping pressure.Liquid level decline when container (15), the tongue tube (13) of magnetic float (17) control disconnects, contact coil J and can not get this moment, major loop can not send, pressure can not be kept and descend, the water program makes magnetic float (17) buoyance lift once more up to entering into, could send electrical heating again, finishes automatic time delay moisturizing function.
Float (17) can not make its conducting when liquid level is lower than tongue tube (13), but when water intaking, push rod (20) can make tongue tube (22) closure, thereby also can send electricity to major loop when draining, produces the discharge that steam promotes boiling water.
Series electrical source switch (63) in control loop can make this water boiler shut down when it is turn-offed, be in series with indicator lamp (23) behind this switch (63), indicates the startup-shutdown situation with it.
When using different ac voltage; Or when using direct current supply,, can form the supply line under the various conditions as long as select the parameter and the electrothermal piece parameter of corresponding contactor coil for use.
The mode that this water boiler is heated with pressure sensing control makes water temperature reach boiling point or more than the boiling point, has solved the shortcoming that prior art water heater water does not boil, even also can obtain high-temperature water under environment under low pressure such as plateau and high-altitude.Also can supply level pressure steam in case of necessity.Owing to be closed container, water is not evaporated yet under long-term insulation, thus the energy saves energy; protection water quality and long run supply boiling water; this water boiler general structure is convenient to airtight, and management is convenient in safety and sanitation; the automaticity height; program is reasonable, and is easy and simple to handle, with low cost; of many uses, be easy to produce.
