The shape memory alloy temperature control valve can be widely applied to various hot water devices or devices which needs achieving temperature control over fluid.
Description
Technical field
The utility model relates to the control valve that adopts marmem, controls flow of fluid in the certain temperature range by the distortion of marmem, particularly is a kind of shape memory alloy temperature control valve.
Background technique
At present, all need water flow control valve as equipment such as water heaters.But present water flow control valve all can not be effectively according to the closure of the temperature regulation valve of current, cause wasting or the generation of accident such as scald.Existing control valve has the cost height, complex structure, and performance is reliable inadequately, shortcomings such as operation inconvenience.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned deficiency, has designed a kind of shape memory alloy temperature control valve.
Above-mentioned purpose is realized by following technical proposals:
The utility model comprises: handwheel, valve rod, gland, packing, common spring, piston, connecting rod, spring seat, valve body, shape memory alloy spring, plug.The valve body top of its shape memory alloy temperature control valve is circular cone shape, the one-level ring-shaped step is arranged at the bottom, longitudinal center is provided with center hole, transverse center is provided with import, outlet, import is communicated with the active chamber of outlet by piston, be the serpentine passage, import and center hole lower end are provided with communication channel, so that transferring heat energy, the center hole bottom is provided with internal thread, on plug is arranged, shape memory alloy spring is equipped with on plug top successively, the piston that spring seat is connected with connecting rod, common spring, valve rod, center hole top is provided with the packing chamber, and packing is housed, and the gland that is threaded with valve body compresses packing, valve rod is provided with outside thread, pass with gland center hole screw-internal thread fit, the upper end is provided with handwheel, so that manual tune.
Working principle: the shape memory alloy spring that selection has certain characteristic temperature, when contacting when the current that in valve, have been full of uniform temperature and with marmem, shape memory alloy spring can deform, the masterpiece that produces by common spring and memory alloy spring is used in and makes the piston motion on the piston, the conversion of motion that is about to shape memory alloy spring is the motion of piston, the position difference that piston is reached, the purpose of realization temperature control current.
The beneficial effects of the utility model are: thus taken full advantage of shape memory alloy spring in deform the up and down effect of the upper and lower motion control current that promote piston of its characteristic temperature.Simple in structure, sensitive reliable, durable in use, cost is low, is easy to promote, and can use at various hot water widely or needs convection cell to realize on the equipment of temperature control.
