Abstract
The utility model relates to a shape memory alloy temperature control valve for a solar water heater. The utility model is characterized in that a bidirectional drive element which is formed by a shape memory alloy spring and a common spring is used for opening and closing a valve. The utility model has the advantages of simple structure, reliable performance, uneasy damage, small volume, light weight, low cost, and convenient use, can be used in the water heater with other type, and can also be used as the temperature control valve for the other liquid transportation.
Description
The utility model is a kind of solar water heater temperature control valve that adopts shape memory alloy spring.
Up to the present, the thermostat valve that is used for solar water heater has:
1, the thermostat valve of forming by electronic temperature sensing device and solenoid valve;
2, direct current type heating power variable valve;
3, adopt the thermostat valve of shape memory alloy material.
More than the defective of these three kinds of thermostat valves be: the 1st kind must have additional power source, and this has just limited the application of solar water heater; Be filled with extraordinary paraffin wax or fluorine Lyons in the 2nd kind the temp-sensitive apparatus, in case leak, thermostat valve will be malfunctioning, even lost efficacy; The 3rd kind marmem is made butterfly, what also have makes cylindrical spring, but because complex structure, the manufacture process requirement height, and cost is high and be difficult to promote.
The objective of the invention is in order to overcome the shortcoming of above-mentioned solar water heater temperature control valve, and the thermostat valve a kind of simple in structure, easy to utilize of design.
Structure of the present utility model as shown in Figure 1, among the figure: the 1st, spool, the 2nd, position-limited rack, the 3rd, shape memory alloy spring, the 4th, supporting frame, the 5th, bias spring, the 6th, housing, the 7th, bonnet (double as adjusting nut), the 8th, valve rod (double as guide rod).
Spool 1, supporting frame 4 and valve rod 8 are connected as a body; Position-limited rack 2 and memory alloy spring 3 and bias spring 5 are enclosed within respectively on the valve rod 8 successively, link to each other with bonnet 7.
There is pipe thread 9 at outer surface two ends at housing 6, can directly be connected on the water heater outlet.The spring 3 that marmem is done and be cylindroid helicalcoil compression spring with the bias spring 5 that common spring is done.
Accompanying drawing 2 is structural drawing of position-limited rack 2.
Accompanying drawing 3 is structural drawing of back valve gap 7.
Be connected on the outlet pipe of water heater of the present utility model 9 during use, like this, when water temperature is raised between temperature controlled region in the heat collector of solar water heater, shape memory alloy spring 3 is just replied elongation, the restoring force that produces is a fulcrum with position-limited rack 2, promotes supporting frame 4 and moves, and so just opens valve 1; Meanwhile, supporting frame 4 compresses bias spring 5 again, when water temperature is lower than temperature controlled region in the heat collector, and the shape memory alloy spring deliquescing, the back stretch of bias spring 5 is by supporting frame 4 compression shape memory alloy springs 3, with valve closing.
The utility model is owing to adopted marmem thereby temperature-sensitive sensitivity, and valve switch is rapid, stable performance; Reasonable in design in addition, make it simple in structure, preparation process is uncomplicated, and volume is little, and is in light weight, and cost is low, and is not fragile, easy to install.
The utility model can be used on other type of water heaters, can also wide application prospect be arranged as the thermostat valve of other liquid transport.
Claims (3)
1, a kind of marmem solar water heater temperature control valve is characterized in that, spool, and supporting frame and valve rod are connected as a body; The position-limited rack memory alloy spring is enclosed within successively on the valve rod respectively with bias spring and links to each other with bonnet.
2, a kind of marmem solar water heater temperature control valve as claimed in claim 1 it is characterized in that shape memory alloy spring and bias spring all are cylindroid helicalcoil compression springs, but bias spring is common spring.
