Abstract
The utility model relates to a valve of a small pipe system of gas and liquid working substances, particularly a memory change valve used for changing the flowing direction of the working substance in the small pipe systems. The utility model can be realized by using a valve body (1), a valve core shaft (2) arranged in the valve body, a shape memory alloy spring (3), an end cover (4), a PTC ceramic heater (5), etc. to form the memory change valve. The utility model has the advantages of low cost, smooth starting, no impact force, electricity failure after the valve core shaft (2) shifts, electrical energy saving, no noise at the time of starting and work, reliable use and long service life. The utility model not only can be suitable for refrigerators, air conditioners, water heaters, etc., but also can be suitable for the small pipe system of the gas and liquid working substances.
Description
The utility model relates to a kind of valve of the small-sized pipe-line system of gas, liquid working medium, particularly working medium in the small-sized pipe-line system is flowed to the memory selector valve of conversion.
The inventor declares " alloy expansion valve ", the patent No.: ZL92 2 36247.5 on October 8th, 1992.Because the development alloy expansion valve in several years finds to adopt 25 watts of electric heating tube core heating life-spans short, not power saving.
The purpose of this utility model provides a kind of novel valve that improves, its advantage: make simple in structurely, price is low, can cut off the power supply after poppet shaft is axially displaced, saves electric energy, further improves working life, has enlarged application area.
The purpose of this utility model is achieved in that and adopts the marmem of new material to be made into screw type alloy spring, the spring expanded by heating, and it is axially displaced to produce expansive force actuating valve mandrel.It is to adopt the PTC ceramic heater that spring is heated, and heater adopts the ceramic plate of ring.
The concrete structure of model utility is provided by following enforcement and accompanying drawing thereof.
Fig. 1 is according to the total sectional drawing that the utility model proposes improved concrete structure.
Describe in detail according to the utility model proposes improved concrete structure and working condition below in conjunction with Fig. 1.
The memory selector valve of the small-sized pipe-line system of gas, liquid working medium has a valve body (1), a poppet shaft (2) is arranged in the body, respectively there is a shape memory alloy spring (3) at the two ends of axle, place in the end cap (4), end cap (4) and valve body (1) welding are provided with PTC ceramic heater (5) in the outside of end cap (4).
The working condition of this valve: behind a termination energize of valve, the heating of PTC ceramic heater, heat will be passed to screw type alloy spring (3) by end cap (4), the spring expanded by heating, it is axially displaced that the expansive force of alloy spring promotes poppet shaft (2), the displacement of poppet shaft (2) has changed the relative position in three holes and poppet shaft (2) hole of valve body (1), has promptly changed the flow direction of working medium.Ending the other end when poppet shaft (2) by end displacement can cut off the power supply, and reaches the saving electric energy.
After the other end of this valve is connected power supply, the heating of PTC ceramic heater, heat will be passed to screw type alloy spring (3) by end cap (4), the spring expanded by heating, it is axially displaced that the expansive force of alloy spring promotes poppet shaft (2), the displacement of poppet shaft (2) has changed the relative position in three holes and poppet shaft (2) hole of valve body (1), has promptly changed the flow direction of working medium.
After an end of valve was connected power supply again, equally going round and beginning again with aforementioned process, working medium flowed in the change system.
The utility model is not only applicable to refrigerator, air conditioner, water heater, shower etc.; And it is also suitable to the small-sized pipe-line system of gas, liquid working medium.
This valve is new design, has brought the accessory of desirable the best to scientific research and new product development.
