Fig. 2 is embodiment of the present invention 1 a float polycrystalline substance schematic representation;
Fig. 3 is the structural representation of embodiment of the present invention 2.
Embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
Mode of execution 1:
Generally swelling water tank is located at the peak of system, so the present embodiment expansion tank is not equipped with nitrogen, the memory space of the interior pure water of expansion tank just becomes big like this, just can lean on the gravity of water to come system is carried out moisturizing.The liquid level pressure stability device of expansion tank as shown in Figure 1 in the sealing and circulating constituent of present embodiment.On the top of expansion tank 6 funnel-shaped container 5 is housed, the top of funnel-shaped container 5 is sealing covers 4.Funnel-shaped container 5 welds together with expansion tank 6.Float is equipped with in expansion tank 6 inside, the structure of float bottom 12 as shown in Figure 2, such structure is in order to make float can be good at swimming on the water surface.Expansion tank 6 inwalls have the slideway of suitable cross structure, and slideway length is the pairing liquid level change scope of the liquid level pressure of expansion tank that airtight constituent allows 6.Being equipped with pillar 14 on the float bottom 12, is sealing plug 13 on the pillar 14.Float is made by the lightweight material of water-fast erosion.The bottom of expansion tank 6 is connected with the water main of airtight constituent 8, and pressure transmitter 7 is housed on the water main 8.On the attached pipeline on the right side, bottom of expansion tank 6 electric valve 9 is housed, electric valve is connected to small-sized water storage tank 10 for 9 times.On the attached pipeline of funnel-shaped container 5 upper right drip pump 3 is housed, manual three-way valve 2 is equipped with on drip pump 3 right sides.Manual three-way valve 2 right sides are connected with outside water pipe 1, and manual three-way valve 2 bottoms are connected with inner water pipe 11, and inner water pipe 11 is connected with small-sized water storage tank 10.
Working principle: as shown in Figure 1, 2, the initial water filling of sealing and circulating constituent can promptly be turned on the sealing cover 4 at funnel-shaped container 5 tops by artificial recharge, directly pours into required pure water or water and ethylene glycol mixture; Also can carry out automatic water filling by suction pump 3, manual three-way valve 2 and outside water pipe 1.Along with the Nei Shui of system is on the increase, water in the expansion tank 6 constantly rises, when the water yield in the expansion tank 6 reaches system and allows the liquid level pressure minimum value of (setting), 12 beginnings of float bottom are along the upwards operation of expansion tank 6 inwall slideways, when the water yield in the expansion tank 6 reached system and allows the liquid level pressure maximum value of (setting), the sealing plug 13 on the pillar 14 was blocked the water intake of expansion tank 6 just.Like this, the water of sealing and circulating constituent is filled.Contain the standby water of 3/4 capacity in the funnel-shaped container 5.
In sealing and circulating constituent running, because ambient temperature reduces, rubber hose is partly shunk with the water yield and is dwindled in the system, make the drawdown of expansion tank 6, sealing plug 13 on the float pillar 14 just leaves the water intake of expansion tank 6 so, and the standby water in the funnel-shaped container 5 just cover in the expansion tank 6, when the water yield in the expansion tank 6 reaches the liquid level pressure maximum value that system allows, sealing plug 13 on the float pillar 14 is blocked the water intake of expansion tank 6 again just, and moisturizing finishes.When ambient temperature raises, the rubber hose demi-inflation and the water yield increase in the system, when the liquid level pressure of expansion tank 6 surpassed the liquid level pressure maximum value that system allowed, the electric valve 9 on the attached pipeline on the right side, bottom of expansion tank 6 was opened, and the water in the expansion tank 6 flows into small-sized water storage tank 10; When the liquid level pressure of expansion tank 6 reached the liquid level pressure maximum value that system allows, electric valve 9 was closed automatically.The liquid level force value of expansion tank 6 is measured by the pressure transmitter on the water main 87, and is sent to the constituent control section, according to the liquid level force value, determines whether opening and closing electric valve 9.When electric valve 9 is opened, delayed startup suction pump 3, when electric valve 9 is closed automatically, time-delay closing suction pump 3, this is in order to make the water in the small-sized water storage tank 10 can in time mend in the funnel-shaped container 5 by inner water pipe 11, form oneself's circulation, these can be finished by the constituent control section.
Mode of execution 2:
Referring to Fig. 3, on the basis of mode of execution 1, float is not housed in expansion tank 6 inside, do not have slideway at expansion tank 6 inwalls, promptly do not adopt Floater Structure.With expansion tank 6 connecting tube places electric valve 15 is installed at funnel-shaped container 5.In the initial water filling of sealing and circulating constituent, open electric valve 15, when the water yield in the expansion tank 6 reached system and allows the liquid level pressure maximum value of (setting), electric valve 15 was closed.In sealing and circulating constituent running, when the liquid level pressure of expansion tank 6 is lower than the liquid level pressure minimum value that system allows, open electric valve 15, when the water yield in the expansion tank 6 reached system and allows the liquid level pressure maximum value of (setting), electric valve 15 was closed.Equally, the liquid level force value of expansion tank 6 is measured by the pressure transmitter on the water main 87, and is sent to the constituent control section, according to the liquid level force value, determines whether opening and closing electric valve 15.Other composition, Placement are identical with mode of execution 1.
