The internal pressure of water heater；
S2, closes the solar water heater, and the solar water heater enters off working state, the heat-conducting medium hair
But, the regulating device adjusts the internal pressure of the solar water heater to raw food.
Step S1 specifically, open the solar water heater, the heat-conducting medium in the heat collecting pipeline due to
Solar energy effect heat absorption causes to elevate the temperature, and the compressor provides the heat-conducting medium stream that pressure causes the heat collecting pipeline
Heat exchange of the higher heat-conducting medium of temperature in the water tank with the heat medium is realized to the heat exchange pipeline, it is complete
At the heating operation of the solar water heater；Due to making in the pressure effect of compressor and the heat expansion of the heat collecting pipeline
With causing to increase sharply in the heat exchange inlet and the input pressure of thermal-arrest liquid outlet junction, pass through described first
The adjusting of expander avoids the input pressure from higher peak value occur, stablizes the input pressure；Due in the heat exchanger tube
The heat-conducting medium heat is lost in road, and the heat-conducting medium volume reduces, the heat exchange liquid outlet in special time period
It is certain negative pressure with the output pressure at the thermal-arrest inlet link position, it can be fast by the adjusting of second expander
Negative pressure described in velocity modulation section guarantees the stabilization of the output pressure.
The specific adjustment process of regulating device is, when the input pressure increases, described in the heat-conducting medium promotion
Movable cock body is axially moved, and the connection of the guide rod and the pilot hole corrects the motion stops body because pressure unevenness is made
At end slope, guarantee that the movable cock body carries out stable axial movement；Under the squeezing action of the movable cock body, institute
The internal pressure for stating pressure-releasing chamber accordingly changes, and the movement of the pressure release movable block causes the pressure release cavity volume holding to be basically unchanged
To balance the internal pressure of the pressure-releasing chamber, the spatial volume by expanding the pressure pocket is dropped with reducing the input pressure
The peak value of the low input pressure；When the input pressure reaches peak value and gradually weakens, the pressure release movable block is described
The rebound effect of elastic diaphragm moves to initial position next time, while the movable cock body also moves back, and guarantees that the heat is followed
The stabilization of pressure in loop system.
Since the heat collector constantly heats the heat-conducting medium, the solar water heater is being opened until work is steady
During determining state, the heat-conducting medium bulk temperature in the heat circulating system, which constantly rises, reaches a stable temperature
State.The equilibrium temperature state is related with external environment, when ambient temperature is higher and illumination is sufficient, the equilibrium temperature shape
The bulk temperature of the heat-conducting medium is higher under state, and generally 150~180 DEG C；When ambient temperature is lower or illumination is insufficient, institute
The bulk temperature for stating the heat-conducting medium under equilibrium temperature state is lower, generally 70~90 DEG C；Due to the equilibrium temperature shape
State changes with external environment state change, when the heat-conducting medium reaches the equilibrium temperature state or thermally conductive Jie
During matter bulk temperature is raised, the heat expansion effect of the heat-conducting medium causes the heat circulating system internal pressure integrally to increase
Add, the activity cock body constantly moves under the internal pressure effect constantly enhanced, since the movable cock body is in moving type
State, the pressure pocket and the pressure-releasing chamber are in equilibrium state, and pressure is equal to pressure in the pressure-releasing chamber, institute in the pressure pocket
Pressure in pressure-releasing chamber is stated to change, the pressure release with the change of the variation of the heat-conducting medium volume inside the heat circulating system
Movable block is simultaneously to moving outside the partition；When the heat circulating system internal pressure reaches pressure-bearing particular value, i.e. institute
When stating pressure in pressure-releasing chamber and reaching the pressure-bearing particular value, the moving distance of the pressure release movable block causes the sealing ring to institute
The sealing state for stating relief hole releases, and the pressure release chamber air is sprayed from the relief hole rapidly, pressure in the pressure-releasing chamber
It reduces rapidly；Since the pressure pocket internal pressure is powerful in pressure in the pressure-releasing chamber at this time, the activity cock body continues axial move
Dynamic, pressure continues to reduce in the pressure pocket, and the heat circulating system internal pressure is caused to be reduced to the pressure-bearing particular value, institute
Pressure release movable block to be stated to move back under the rebound effect of the elastic diaphragm, the sealing ring is again sealed off the relief hole,
The pressure-releasing chamber and the pressure pocket return equilibrium state, realize that the pressure release to the heat circulating system internal pressure is grasped
Make；Guarantee that the heat circulating system internal pressure is in the pressure-bearing particular value by the automatic adjustment of the regulating device
Within, improve the safety of the solar water heater；The pressure-bearing particular value is generally less than the solar energy water heater pipe
Maximum resistance to compression value.
Step S2 is specifically, when closing the solar water heater, and the heat-conducting medium is sent out in the heat circulating system
But, the heat-conducting medium bulk temperature declines raw food, causes the heat circulating system internal pressure to reduce, the motion stops
Body carries out retraction axial movement, and the heat-conducting medium volume-diminished is to certain state, i.e., described inside the heat circulating system
When pressure reaches certain state in pressure-releasing chamber, the moving distance of the pressure release movable block causes the sealing ring to the relief hole
Sealing state release, the air of the adapter cavity carries out the pressure-releasing chamber, the pressure-releasing chamber internal pressure from the relief hole rapidly
It is strong to be promoted rapidly；Since the pressure-releasing chamber internal pressure is powerful in pressure in the pressure pocket at this time, the activity cock body continues axial
Mobile, pressure continues to reduce in the pressure pocket, and the pressure release movable block moves back under the rebound effect of the elastic diaphragm,
The sealing ring is again sealed off the relief hole, and the pressure-releasing chamber and the pressure pocket return equilibrium state, realizes to described
The blower operations of the heat circulating system internal pressure；Guarantee the thermal cycle by the automatic adjustment of the regulating device
Internal system pressure is steady, improves the safety of the solar water heater.
The foregoing is merely presently preferred embodiments of the present invention, is merely illustrative for the purpose of the present invention, and not restrictive
's.Those skilled in the art understand that in the spirit and scope defined by the claims in the present invention many changes can be carried out to it,
It modifies or even equivalent, but falls in protection scope of the present invention.
