Embodiment
Accompanying drawing is the structure principle chart of the specific embodiment of the present invention.Valve mainly comprises valve body (1), locking element (2), seal ring (3), big piston (4), link (5), spool (6), reset spring (7), magnetic ring component (8), magnetic column assembly (9), memory alloy (10), baffle plate (11), valve gap (12), spool overcoat (13), valve rod (14), small piston (15), big piston pad (16); The valve body water outlet (17) that cylinder type is arranged in the valve body (1), valve body water outlet (17) top is equipped with the big piston (4) that cooperates the controlled water flow size with it, big piston pad (16); Locking element (2) is fixedly mounted on big piston pad (16) by screw thread the bottom of big piston (4), there is from top to bottom a relief hole centre of locking element (2), there is the small piston (15) that is used with it the relief hole upper end, small piston (15) is installed in the following top of valve rod (14), and small piston (15) can move up and down under the drive of valve rod; Valve rod (14) passes link (5), spool (6) bottom, memory alloy (10), baffle plate (11), reset spring (7) and passes spool (6) upper end portion again; Link (5) is connected with big piston (4) top by screw thread, on big piston (4) circumference seal ring (3) is arranged, big piston (4) have from top to bottom one with the identical pressurized hole of the interior water intake of valve body (1); The top of spool (6) is equipped with magnetic column assembly (9); The top of valve body (1) is connected with valve gap (12) by bolt, and the circular hole in the middle of the valve gap (12) is connected with spool overcoat (13) by welding, and the outside of spool overcoat (13) is with magnetic ring component (8); Described magnet ring, magnetic column assembly link to each other with the upper magnet same polarity by two, are filled with the magnetic gap sheet between two magnets.
The present invention is work like this, under the valve normal operation, because ambient temperature is not very low, or flow of hot water is arranged through valve, memory alloy (10) presents swelling state, by baffle plate (11) water outlet on promotion valve rod (14), the downward approach locking part (2) of small piston (15) in compression reset spring (7), this moment, the unlatching of valve can be controlled moving up and down of magnetic ring component (8) to realize by the external world by means such as electronic, manual or thermometer bulbs; For example can thermometer bulb be installed in the upper end of magnetic ring component (8), when ambient temperature does not reach the expansion temperature of thermometer bulb, the mechanical device that is attached thereto be failure to actuate (or actuating length is not enough), the spring of magnetic ring component below is pushed magnetic ring component to high position, under magnetic coupling interaction, magnetic ring component (8) pulling magnetic column assembly (9) moves up, magnetic column assembly (9) drives spool (6) upwards, spur valve rod (14) more upwards, force the small piston (15) of stem bottom to leave relief hole on the locking element (2) that is connected with big piston (4), because the hydraulic pressure on big piston (4) top is released, valve rod further drives big piston (4) by link (5) and moves up, under the acting in conjunction of hydraulic pressure, big piston pad (16) leaves the water outlet (17) in the valve body, valve open; Same reason, when needing throttle down, only magnetic ring component (8) need be moved down, after the small piston (15) of valve rod (14) bottom is blocked the relief hole of locking element (2), hydraulic pressure is by the pressurized hole of big piston (4) on it, rapidly big piston pad (16) is pressed on the water outlet (17) in the valve body valve closing.After working as valve closing the winter of cold, the various radiators that are connected with valve, valve just might be freezing; When the present invention is lower than the operating temperature temperature of memory alloy (10) in ambient temperature, original contraction state will be returned to, this moment, reset spring (7) promoted baffle plate (11) upwards under the effect of elastic restoring force, at pulling valve rod (14), small piston (15) upwards, valve open, the higher water of temperature flows out, and after the inflow of hot water was expanded memory alloy (10), valve was closed again, so the freezing of water appliance avoided in circulation.
