Description
Technical field
The utility model relates to a kind of solenoid valve.
Background technique
Existingly a kind ofly drive steel ball to move by iron core thus open or the solenoid valve of cut-off valve seat valve mouth, because steel ball and valve seat are all be made up of steel material, therefore be sealed into hard sealing between steel ball and valve seat valve port, cause sealing not exclusively, there is leakage rate; In addition, if there is impurity in the air inlet of system, valve seat valve port is in the process opening closedown easily damages, and thus there is the hidden danger of easily leaking, shortens the working life of solenoid valve.
Model utility content
The purpose of this utility model is to provide a kind of good seal performance, long service life solenoid valve.
The technological scheme realizing the utility model object is: a kind of solenoid valve, comprises valve seat, suction tude, outlet pipe, outer cover, chock plug, spring, iron core, coil, steel ball and spool; The sidewall of described valve seat is provided with the inlet hole being communicated with valve base cavity, and one end of suction tude is fixed in the inlet hole of valve seat; The two ends of the inner chamber of described valve seat are fixedly connected with one end of outer cover with outlet pipe respectively and are communicated with; The other end interference fit of described chock plug and outer cover is also welded; The endoporus of described iron core and outer cover is slidably connected; Described spring is arranged between iron core and chock plug; Described coil is fixed on outer cover outside; The one end be communicated with outlet pipe in the inner chamber of described valve seat is provided with mounting groove; Described spool is fixed in the mounting groove of valve seat; Described steel ball is arranged on the end near one end of spool on iron core, and the centre of sphere of steel ball is positioned on the axis of the center hole of spool; Described spool is made up of soft material.
Described iron core is provided with groove near the center of one end of chock plug; Described spring is arranged in the groove of iron core.
Described spool riveted joint is fixed in the mounting groove of valve seat.
Described spool is made up of teflon.
Have employed technique scheme, the utility model has following beneficial effect: (1) spool of the present utility model is made up of soft material, is sealed into soft seal between steel ball and spool, and sealability is better; Meanwhile, even if there is impurity in the air inlet of system, also can not impact sealability, longer service life.
(2) spring of the present utility model is arranged in the groove of iron core, and this structure can avoid spring to deflect the phenomenons such as distortion when compressing, and improves stability and the reliability of solenoid valve quality of product further.
(3) spool riveted joint of the present utility model is fixed in the mounting groove of valve seat, and stable connection is reliable.
(4) spool of the present utility model is made up of teflon, and teflon has the feature of antiacid alkali resistant, anti-various organic solvent, is dissolved in all solvents hardly; Meanwhile, teflon also has resistant to elevated temperatures feature.
