Description
Technical Field
The invention relates to the technical field of heat energy control, in particular to a thermosensitive magnetic control type thermostat.
Background
Some industrial controls and applications requiring thermal energy control often require the use of a thermostat valve (also called thermostat), such as: in central heating equipment in winter in the north, the valve is opened after water is heated to a certain temperature, so that the loss of heat can be well reduced, and the energy consumption of boiler fuel is reduced.
For another example: when the automobile diesel internal combustion engine is cold started at the subzero temperature in winter in the north, the engine is difficult to start and needs to consume certain fuel for preheating because the temperature of the engine body is low. One reason for this is that the diesel oil has a high ignition temperature and a low viscosity, and is not easily atomized when sprayed into the cylinder and not well mixed with air, and the cylinder needs to be preheated to a certain temperature, so that the diesel oil can be completely combusted. Therefore, a thermostat is arranged in a cooling circulation loop of the automobile, and the thermostat has the functions of closing the cooling circulation loop with a radiator when the engine is in cold start, enabling the temperature of an engine cylinder to quickly rise, and enabling diesel oil to be completely combusted, and opening a cooling pipeline valve when the temperature of the engine reaches about 80 ℃, so that the starting time can be shortened, and the consumption of the diesel oil can be reduced.
At present, a paraffin wax type thermostat is commonly used in thermostats used for automobile engines. The structure principle is as follows; when the cooling temperature is lower than a specified value, the thermostat temperature sensing body refined paraffin is solid, the thermostat valve body is in a closed state under the action of the spring, when the temperature of the cooling liquid reaches the specified value, the paraffin begins to melt and gradually becomes liquid, the volume begins to increase and presses the rubber tube to enable the rubber tube to contract, the rubber tube acts on an upward force of the push rod while contracting, the push rod pushes the valve body downwards to open the valve, and the cooling liquid flows into a cooling cycle.
However, the energy-saving temperature control valve based on the application has the advantages of complex structure, high manufacturing cost, troublesome application control and high failure rate. Therefore, there is a need for a thermostat that is simple in structure, easy to manufacture, and easy to control.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
Herein, the present invention provides a heat-sensitive magnetic controlled thermostat, in which the direction indicated by the arrows in fig. 1 and 2 is the direction of water flow.
Referring to fig. 1-6, the present invention provides a thermal sensitive magnetic controlled thermostat, which comprises a tubular housing 1, a hollow annular protrusion 2 disposed on the inner wall of the housing, and a movable swing plate 3 pivotally connected inside the housing; this activity balance staff 3 is located between protruding 2, the longitudinal section of activity balance staff is the Z type, including last balance staff 31, accepting part 32, the lower balance staff 33 that connect gradually, when going up the balance staff and placing at the level, go up balance staff 31 and inhale subassembly 4 and protruding 3 up end magnetism actuation through multiunit temperature sensing magnetism, when lower balance staff 33 was placed at the level, lower balance staff 33 was through the lower terminal surface magnetism actuation of multiunit temperature sensing magnetism subassembly 4 and protruding 2, temperature sensing magnetism subassembly 4 can be according to ambient temperature change magnetism actuation ability. Here, the housing 1 may be designed to be a circular tube or a square tube according to production requirements, and similarly, the hollow annular protrusion and the movable swing plate are designed to be in a shape adapted to the housing, and the change of the shape of the components does not affect the implementation effect of the present invention.
Here, referring to fig. 1-3, each set of the heat-sensitive magnetic assemblies 4 includes a heat-sensitive soft magnet 41 disposed on the movable swing plate and a hard magnet 42 disposed on the protrusion, and the heat-sensitive soft magnet 41 and the hard magnet 42 in each set are disposed correspondingly. The thermosensitive soft magnet 41 is mainly composed of a thermosensitive metal material and a thermosensitive ferrite, and ferromagnetic substances in the thermosensitive soft magnet lose ferromagnetism and become paramagnetic when the temperature is higher than a certain temperature (the transition temperature is the curie temperature point). While the ferromagnetic substance in the heat-sensitive soft-magnetic body regains ferromagnetism when the temperature is lower than a certain temperature (the transition temperature is the curie temperature point). When the thermally sensitive soft magnet 41 has ferromagnetism, the thermally sensitive soft magnet 41 and the hard magnet 42 are attracted to each other by the magnetic force. When the soft heat-sensitive magnet 41 loses ferromagnetism, the soft heat-sensitive magnet 41 and the hard magnet 42 cannot magnetically attract each other. The skilled person can adjust the proportion of material in the heat-sensitive soft-magnetic body to set the curie temperature point of the heat-sensitive soft-magnetic body.
In this embodiment, referring to fig. 5, the housing 1 is a circular tube, the movement axis of the receiving portion 32 is perpendicular to but not intersected with the axis of the housing 1, the movement axis of the receiving portion 32 is offset to one side of the housing axis (i.e., eccentrically disposed), the protrusion 2 is provided with two symmetrically disposed notches 21, the two notches divide the protrusion into a first arc section 22 and a second arc section 23 concentrically disposed on the inner wall of the housing, the arc length of the first arc section 22 is greater than that of the second arc section 23, the receiving portion 32 is located between the first arc section 22 and the second arc section 23, the upper swing plate 31 and the lower swing plate 33 are semicircular, the upper swing plate 31 can be tightly connected with the top of the first arc section 22, and the lower swing plate 33 can be tightly connected with the bottom of the second arc section 23.
Referring to fig. 1 and 2, for example, when the thermostat is applied to a heating device, the thermostat is installed at an outlet of a hot water pipe of the heating device, a change in water temperature can affect a magnetic characteristic of the thermosensitive soft magnet, when the water temperature is lower than a curie temperature point of the thermosensitive soft magnet, the thermosensitive soft magnet 41 installed on the movable swing plate 3 and the hard magnet 42 provided on the protrusion 2 are attracted to each other under a magnetic force, the movable swing plate 3 is tightly closed, when the water temperature gradually increases, the temperature of the thermosensitive soft magnet 41 also increases, when the thermosensitive soft magnet 41 reaches or exceeds the curie temperature point thereof, the magnetic force of the thermosensitive soft magnet disappears, and the thermosensitive soft magnet is pushed to change from a horizontal placement state to an inclined state under the pressure of water.

When no water pressure exists, the temperature of the thermosensitive soft magnet 41 gradually drops below the curie temperature point, the ferromagnetism of the thermosensitive soft magnet 41 recovers, the thermosensitive soft magnet 41 and the ferromagnetic body 42 form a magnetic attraction force, and because the weight of the upper swing plate 31 is greater than the gravity of the lower swing plate 32, the movable swing plate 3 is under the action of lever balance, the upper swing plate 31 approaches towards the first arc section direction, and the lower swing plate 33 approaches towards the second arc section 23 direction. The movable swing plate 3 is turned over to be in a horizontal state again under double acting force, and the thermostat is closed.
