Different magnetism so that movable core can be pulled together under normal conditions with secured core, can keep movable core and fixation
Loosening problem will not occur under normal conditions for iron core.Movable core is facilitated well in the case where original spring positions in itself with consolidating
Fixed core is fixed.
Preferably, the magnetic pole of the secured core adjacent with the movable core is S poles, adjacent with the secured core
The movable core magnetic pole for N poles, the magnetic pole of the movable core adjacent with permanent magnet is S poles, with movable core phase
The magnetic pole of the adjacent permanent magnet is N poles.By the design of above-mentioned specific secured core, movable core and permanent magnet magnetism,
It realizes that movable core is attached together under normal conditions with secured core, piping extruding is made not circulating inside it.
It is preferably located on the valve deck where above piping and is provided with the inner fovea part being recessed inwardly, the inner fovea part and institute
It states to squeeze and be correspondingly arranged above and below rubber pad.So when electromagnetic drive part is upward squeezes rubber pad, in the cooperation of inner fovea part
It is lower to be convenient for that realization piping by piping intrinsic block, is facilitated to squeeze the internal purpose that circulated.
Preferably, the cross-section structure of the inner fovea part is triangular structure or rectangular configuration or trapezium structure.By using
Said structure：Triangular structure, the seamed edge of rectangular configuration are contacted to rainy piping, and the upper bottom edge of trapezium structure is contacted with piping.
When extruding rubber pad moves upwards, the relatively narrow contact surface in the piping top contact surface wider with lower part overlaps, such distribution
Mode is beneficial to block the inside of piping.
Preferably, the piping is piping made of fluorine silicone rubber or natural rubber.Using above-mentioned material so that piping has
There are preferably heat-resisting, cold-resistant etc. characteristics, and its plasticity is good, convenient for the repeated multiple times extruding recovery operation of piping.
