Embodiment
Shown in accompanying drawing 1, the present embodiment comprises stepper motor 1, mangetic core assembly 4, shell 5, shell 5 is provided with valve port, mangetic core assembly 4 comprises valve core housing 7, spool 8, spool 8 is provided with valve 14, mangetic core assembly 4 also comprises fixed block 6, Sealing 10, elastic member 9, valve core housing 7 is enclosed within outside spool 8, spool 8 is provided with fixed block installation position 11, boss 12, groove 13, valve core housing 7 is provided with elastic member mounting hole 15, elastic member 9 to be arranged on boss 12 and to be arranged in elastic member mounting hole 15, Sealing 10 is arranged in groove 13, fixed block 6 is arranged on fixed block installation position 11 place makes spool 8 top be connected with valve core housing 7 top movable, the diameter of valve 14 is more than or equal to the diameter of valve port.
Elastic member 9 is Compress Spring or elastic caoutchouc, adopts Compress Spring in the present embodiment, connects ancient simple, easy for installation.
Described mangetic core assembly 4 also comprises Sealing 10, and valve core housing 7 is provided with groove 13, and Sealing 10 is arranged in groove 13, and this structure can effectively be avoided occurring water leakage situation in mangetic core assembly 4.
Referring to accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, as a kind of linkage structure of the utility model mangetic core assembly 4, described fixed block 6 is jump ring, and fixed block installation position 11 is the draw-in groove on spool 8 top, and jump ring to be arranged in draw-in groove and to be positioned at above the top end face of valve core housing 7.
Referring to accompanying drawing 6, as the second linkage structure of the utility model mangetic core assembly 4, be that described fixed block 6 is nut with the first structure difference, fixed block installation position 11 is the outside thread on spool 8 top, and nut is connected with outside thread and is positioned at above the top end face of valve core housing 7.
Referring to accompanying drawing 7, as the third linkage structure of the utility model mangetic core assembly 4, be that described fixed block 6 comprises screw and packing ring with the first structure difference, fixed block installation position 11 is the tapped hole at spool 8 top, packing ring is placed on the end face of valve core housing 7 top, and screw is connected with tapped hole through packing ring.
Above-mentioned three kinds of structures are all fairly simple, and elastic member 9 and spool 8 all can be made to be arranged in valve core housing 7, can ensure again when stepper motor rotates simultaneously, spool 8 and valve core housing 7 can be movable relatively.
Preferably, the compressible amount of described elastic member 9 is greater than a helical pitch distance of valve core housing 7, and when stepper motor 1 step-out, elastic member 9 can play effective buffering, prevents stepper motor 1 from damaging.
In use, water (flow) direction as shown by arrows, cold water enters from water intake, then by the opening on valve 14 and shell 5 between valve port, then the heat exchanger of water heater is flowed into from water outlet, stepper motor 1 drives mangetic core assembly 4 to rotate, helical pitch part 3 makes mangetic core assembly 4 move axially when rotary motion simultaneously, regulating water flow like this, diameter due to valve 14 is more than or equal to the diameter of valve port, so can water flow be adjusted very little, so that close, the requirement of the minimum water flow of gas water-heater namely can be met.
When Step motor 1 step-out, when valve 14 is conditioned gapless between valve port, stepper motor 1 also will proceed to rotate, such stepper motor 1 drives valve core housing 7 to rotate, valve core housing 7 moves axially while rotating, and then Compress Spring 9, stepper motor 1 can not be made to damage because of " dieback " of rigidity.
Test proves, the water heater of same model, and using the water Proportional valve of background technique, being adjusted to minimum water flow is that 5L/min is more difficult, and spool 8 is just easy to occur " stuck ", and the ratio damaging stepper motor 1 is very large.Use water Proportional valve of the present utility model, minimum water flow is easy to just can be adjusted to below 2L/min, and can not damage stepper motor due to the buffering of elastic member.
