17 bottom of valve seat offers the groove 14 connecting with container, is provided with sealing element 15 in groove 14.
The use principle of the utility model is as follows:
In the initial state, coil block 3 and no power do not generate magnetic field, and dynamic iron core 31 is in the effect for restoring spring 32
Under move down, meanwhile, tetrafluoro valve rod 21, which is moved down, blocks second channel 12 in the opening in valve chamber 10, and passes through
Tetrafluoro valve stem packing ring 23 is sealed；At this point, flowing into mordant liquid flow matter from first passage 11, and flow into the
In one cavity 101, liquid liquid is limited in the first cavity 101 and cannot flow under the buffer action of tetrafluoro isolation board 22
Enter the second cavity 102, can not flow into coil block bracket 16, in order to avoid coil block bracket 16, dynamic iron core 31 and recovery bullet
Spring 32 etc. is corroded, and causes the damage of solenoid valve body 1；
Coil block 3 is powered by electrical connection section 13, and coil block 3 generates magnetic field, and dynamic iron core 31 is under the influence of a magnetic field
Overcome and moved up under the active force for restoring spring 32, at this point, second channel 12 is left in opening in valve chamber 10 in 21 top of tetrafluoro valve rod
Mouthful, liquid liquid can be flowed out through second channel 12；
When coil block 3 powers off, magnetic field disappears, and dynamic iron core 31 is mobile to valve chamber 10 under the action of restoring spring 32,
Meanwhile tetrafluoro valve rod 21 is moved down and is blocked to second channel 12 in the opening in valve chamber 10, and passes through tetrafluoro valve rod
Sealing ring 23 is sealed, and liquid liquid cannot be flowed out by second channel 12.
In this way, the reciprocating movement of dynamic iron core 31, the reciprocating movement of tetrafluoro valve rod 21 is driven, to realize first passage 11 and the
Connection/barrier between two channels 12, and this solenoid valve body 1, tetrafluoro valve rod 21, tetrafluoro isolation board 22, tetrafluoro valve rod are close
Seal 23 is all to pass through tetrafluoro isolation board 22 and tetrafluoro isolation board using polytetrafluoroethylene material production or corrosion resistant material
Sealing ring 221 is isolated, and is not contacted liquid liquid inside coil block bracket 16, to reach good antiseptic property, is made to clear up
Exhaust solenoid valve can use for a long time in the acid of 100% concentration and the alkaline media of 100% concentration.Solenoid valve body 1 uses poly- four
Fluoride material has good heat-resisting quantity and good lower temperature resistance, and high temperature can be used in 220 degrees Celsius of long-times, low
Temperature can be used in -80 degrees Celsius of long-times, and solenoid valve is enable to have wider application.In addition, passing through the groove of 17 bottom of valve seat
14 connect with other containers, and the excellent sealing of solenoid valve body 1 Yu container is reached using sealing element 15, and liquid liquid is logical from first
Road 11 enters, and flows out after the first cavity 101 from second channel 12, vertical disengaging is formed, to meet work requirements.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
