Description
Technical field
The present invention relates to the control parts of Fluid valve, particularly to a kind of double protection valve lock.
Background technology
Existing magnetic lockable valve, such as Fig. 1, generally comprise valve body 1', valve gap 2', opening and closing element 4', valve rod 5' and magnetic
, above valve body 1', described valve body 1' partly offers the fluid passage of insertion medium vertically for key 6', described valve gap 2',
Described fluid passage has water inlet 11' and outlet 12', described opening and closing element 4' can upper and lower lifting institute in valve body 1'
State between water inlet 11' and outlet 12', threadeded through valve gap 2' with opening and closing element 4' in described valve rod 5' one end, described valve
It is additionally provided with lid 2' and limits the magnetic locking device that valve rod 5' rotates, described magnetic key 6' is provided with for releasing magnetic locking
The unlocking mechanism of mechanism, described magnetic locking device includes bonnet, 3', and described bonnet, 3' is sheathed on above valve gap 2', and leads to
The free end crossing bearing pin 51' with valve rod 5' is fixedly connected, and the end face wall body between described bonnet, 3' and valve gap 2' has phase
The upper lockhole 31' being mutually correspondingly arranged and lower lockhole 21', is provided with lower magnetic steel 7', institute between described upper lockhole 31' and lower lockhole 21'
State the lower section positioned at lower magnetic steel 7' in lower lockhole 21' and be additionally provided with return springs 8', described unlocking mechanism is located at magnetic key
The upper magnetic steel 61' that 6' is upper and described lower magnetic steel 7' position is corresponding, and the upper magnetic steel 61' one end polarity corresponding with lower magnetic steel 7'
Identical setting, when needing Open valve, the general magnetic carried with key is sheathed on above valve gap, because in magnetic key
The magnetic pole of the lower magnetic steel between upper magnetic steel and bonnet, and valve gap is homopolarity, in the presence of magnetic homopolarity phase is repelled, lower magnetic steel
Produce pressure to spring to be entirely retracted in the lower lockhole of valve gap, so that bonnet, can rotate with magnetic key turn, then carry
Ovable valve stem rotates the open and close realizing valve body, when magnetic key does not work and packs up, the lower magnetic between bonnet, and valve gap
Steel by stuck for bonnet, on valve gap so as to can not rotate with other openers, above-mentioned magnetic lockable valve is generally for reality
The demand now produced in batches, its magnetic locking device is generally configured to universal architecture with the unlocking mechanism of magnetic key, is all
