Description
Technical field
The present invention relates to the pilot valve of a kind of electromagnetism four-way change-over valve, belong to solenoid valve market.
Background technology
Electromagnetism four-way change-over valve is the strength member of heat pump type air conditioner, it is adaptable to central authorities, split, window etc.
Air-conditioner.Electromagnetism four-way change-over valve includes pilot valve, and the spool of pilot valve moves axially along conduit can change hair
Air pressure in tubule e, capillary tube s, capillary tube c and capillary tube d, but, the spool of pilot valve itself is also
Not being connected with capillary tube e, capillary tube s, capillary tube c and capillary tube d, it is mainly by sliding bowl laminating valve
Seat, to change the air pressure in capillary tube e, capillary tube s, capillary tube c and capillary tube d, causes when bracket rotates
When sliding bowl staggers with valve seat, not only capillary tube e, capillary tube s, capillary tube c and capillary tube d will collaborate,
And, sliding bowl will separate with bracket.
Summary of the invention
Problem to be solved by this invention is just to provide the pilot valve of a kind of electromagnetism four-way change-over valve, to avoid elder generation
Pilot valve generation capillary tube is collaborated and is slided bowl and comes off from bracket.
For solving the problems referred to above, the present invention provides following technical scheme: the guide of a kind of electromagnetism four-way change-over valve
Valve, including valve body, valve seat and conduit, described conduit is connected on valve body, and described valve seat is arranged in valve body,
