Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of corrosion-resistant leakage-free valve, this valve drives spool action by electromagnetic force, realize opening and closing, the moving element of valve is arranged in the housing of valve, avoids the phenomenon generation that fluid leaks along moving element.
Corrosion-resistant leakage-free valve provided by the present invention comprises the housing 1 of cup-shaped, is positioned at the spool of housing, the diapire of housing is provided with inlet tube 20, the sidewall of housing is provided with outer pipe 30, inlet tube 20 mouth of pipe stretched in housing is provided with valve seat 2, tube wall at the middle part of inlet tube is fixedly connected with a guide sleeve 3 by many roots bar 4, and guide sleeve is coaxial with valve seat; It is characterized in that, described spool is the entirety of " doing " font be made up of magnetic conductive disk 6, attachment post 5, flap 7 and the axis of guide 8 order, the axis of guide 8 to insert ordinatedly in guide sleeve and stretches out, and has Compress Spring 9 that flap can be made to push down valve seat at the external part cover of the axis of guide; Cup-shaped valve gap 14 is sealedly connected with at the oral area 11 of housing, the diapire of valve gap and the magnetic conductive disk of spool leave space between the two in opposite directions, being provided with longitudinal section in valve gap is E shape magnetic core 12, and on the core of magnetic core, cover has field coil 13, magnetic conductive disk can be inhaled to magnetic core when field coil obtains electric; Described valve gap is made up of non-magnetic metallic material, and described magnetic core and magnetic conductive disk are made up of magnetic conductive metal material.
Feature of the present invention is, moving element is spool, and the magnetic force that the motion of spool produces by field coil drives, protruding from housing without movable link on spool, solves the problem that the fluid in prior art in valve leaks along valve rod; Also eliminate the leakage-preventing sealing device between valve rod in prior art in valve and housing simultaneously, make the designs simplification of valve; Another feature of this leakage-free valve is that the motion of spool is for axial, move without spin between spool and valve seat, make sealing surface between spool and valve seat without abrasion, the sealability between spool and valve seat can be kept, in the using process of valve, save the workload of the sealability safeguarded between spool and valve seat.
