Also adjusted by force, so as to realize the regulation to the heat circulating system internal pressure, avoided in the heat circulating system
Portion's hypertonia is too low, ensures the normal work of the novel solar water heater；By the setting of the bearing plate 272,
The separation of heat circulating system and pressure regulating system is realized, avoids leakage and the institute of the heat-conducting medium in heat circulating system
State pollution of the pressure regulating system to the heat-conducting medium.
Embodiment three
A kind of application method of novel solar water heater of the present invention, specific steps include,
S1, opens the novel solar water heater, and the novel solar water heater enters working condition, the collection
Hot device heats to the heat-conducting medium, and the control device controls the heat transfer medium flows, the adjusting means regulation
The internal pressure of the novel solar water heater；
S2, the novel solar water heater is closed, the novel solar water heater enters off working state, described
Heat-conducting medium cools down, and the adjusting means adjusts the internal pressure of the novel solar water heater.
Step S1 is specifically, open the novel solar water heater, the heat-conducting medium in the heat collecting pipeline
Elevated the temperature because solar energy acts on heat absorption cause, the compressor, which provides pressure, causes the heat conduction of the heat collecting pipeline
Medium flow to the heat exchange pipeline and realizes heat of the higher heat-conducting medium of temperature with the heating medium in the water tank
Exchange, complete the heating operation of the novel solar water heater；Due in the pressure effect of compressor and the thermal-collecting tube
The heat expansion effect in road, cause to increase sharply in the heat exchange inlet and the input pressure of the thermal-arrest liquid outlet junction, lead to
The regulation of first expander is crossed, avoids the input pressure from higher peak value occur, stablizes the input pressure；Due to
The heat-conducting medium heat is lost in the heat exchange pipeline, and the heat-conducting medium volume reduces, the institute in special time period
It is certain negative pressure that heat exchange liquid outlet, which is stated, with the output pressure at the thermal-arrest inlet link position, swollen by described second
The regulation of swollen device can adjust the negative pressure rapidly, ensure the stabilization of the output pressure.
The adjusting means specifically adjusts process, when the input pressure increase, 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 is uneven
Caused by end slope, ensure the axial movement that the movable cock body is stablized；In the squeezing action of the movable cock body
Under, the internal pressure of the pressure-releasing chamber accordingly changes, and the movement of the pressure release movable block causes the pressure release cavity volume to keep base
This is constant to balance the internal pressure of the pressure-releasing chamber, and the input is reduced by expanding the spatial volume of the pressure pocket
Pressure, reduce the peak value of the input pressure；When the input pressure reaches peak value and gradually weakens, the pressure release activity
Block moves to initial position next time in the rebound effect of the elastic diaphragm, while the movable cock body also moves back, and ensures
The stabilization of pressure in the heat circulating system.
Due to the heat collector constantly to the heat-conducting medium heat, the novel solar water heater open until
During working stability state, it is steady that the heat-conducting medium bulk temperature constantly rising in the heat circulating system reaches one
Fixed state of temperature.The equilibrium temperature state is relevant with external environment, described when ambient temperature is higher and illumination is sufficient
The bulk temperature of the heat-conducting medium is higher under equilibrium temperature state, generally 150~180 DEG C；When ambient temperature is relatively low or light
During according to deficiency, the bulk temperature of the heat-conducting medium is relatively low under the equilibrium temperature state, generally 70~90 DEG C；By institute
State equilibrium temperature state to change with external environment state change, when the heat-conducting medium reaches the equilibrium temperature shape
During state or the heat-conducting medium bulk temperature are elevated, the heat expansion effect of the heat-conducting medium causes the thermal cycle system
System internal pressure integrally increases, and the movable cock body constantly moves under the internal pressure effect constantly strengthened, due to the work
Dynamic cock body is active, and the pressure pocket and the pressure-releasing chamber are in poised state, and pressure is equal in the pressure pocket
Pressure in the pressure-releasing chamber, in the pressure-releasing chamber pressure with the heat-conducting medium volume inside the heat circulating system change
Change and change, the pressure release movable block is simultaneously to being moved outside the dividing plate；Pressed inside the heat circulating system
Power reaches pressure-bearing particular value, i.e., when pressure reaches the pressure-bearing particular value in described pressure-releasing chamber, the movement of the pressure release movable block
Distance causes the sealing ring to release the sealing state of the relief hole, and the pressure release chamber air is rapidly from the pressure release
Hole sprays, and pressure reduces rapidly in the pressure-releasing chamber；Because now the pressure pocket internal pressure is powerful in the pressure-releasing chamber internal pressure
By force, the movable cock body continues to move axially, and pressure continues to reduce in the pressure pocket, causes inside the heat circulating system
Pressure is reduced to the pressure-bearing particular value, and the pressure release movable block moves back under the rebound effect of the elastic diaphragm, described
Sealing ring is again sealed off to the relief hole, and the pressure-releasing chamber and the pressure pocket return poised state, realize to described
The pressure discharge operations of heat circulating system internal pressure；The thermal cycle system is ensured by automatically adjusting for the adjusting means
System internal pressure is within the pressure-bearing particular value, improves the security of the novel solar water heater；The pressure-bearing is special
Definite value is generally less than the maximum resistance to compression value of the novel solar water heater pipeline.
Step S2 specifically, when closing the novel solar water heater, in the heat circulating system heat conduction be situated between
Matter cools down, and the heat-conducting medium bulk temperature declines, and causes the heat circulating system internal pressure to reduce, described
Movable cock body carries out retraction axial movement, inside the heat circulating system heat-conducting medium volume-diminished to certain state,
When pressure reaches certain state in i.e. described pressure-releasing chamber, the displacement of the pressure release movable block causes the sealing ring to institute
The sealing state for stating relief hole releases, and the air of the adapter cavity carries out the pressure-releasing chamber from the relief hole rapidly, described to let out
Pressure intracavitary pressure is lifted rapidly；Because now the pressure-releasing chamber internal pressure is powerful in pressure in the pressure pocket, the movable cock body
Continue to move axially, pressure continues to reduce in the pressure pocket, resilience masterpiece of the pressure release movable block in the elastic diaphragm
With lower return, the sealing ring is again sealed off to the relief hole, and the pressure-releasing chamber and the pressure pocket return poised state,
Realize the blower operations to the heat circulating system internal pressure；Institute is ensured by automatically adjusting for the adjusting means
It is steady to state the heat circulating system internal pressure, improves the security of the novel solar water heater.
Presently preferred embodiments of the present invention is the foregoing is only, is merely illustrative for the purpose of the present invention, and it is non-limiting
's.Those skilled in the art understands that can carry out many to it in the spirit and scope that the claims in the present invention are limited changes
Become, modification, in addition it is equivalent, but fall within protection scope of the present invention.
