When the safe and reliable gas furnace of the utility model is used with plug valve：Shaft is first pushed, shaft drives needle
It is moved in spool, the bottom end of needle pushes solenoid valve so that solenoid valve is opened, since needle moves the steel ball so that on needle
Disengaging air admission hole, the channel status that intake interface, solenoid valve, air admission hole, nozzle etc. are at this time, and since shaft pushes
Shifting block is driven rotate and triggers the energizations such as microswitch unlatching, porcelain needle on lighter and is lighted a fire, after lighting a fire successfully, thermocouple by
Heat causes solenoid valve to be in opening, unclamps shaft at this time, shaft is rebounded under the resilient force of shaft spring, rotating shaft
The steel ball of adjustable needle and the opening degree of air admission hole, realize that firepower is adjusted.
In conclusion pass through valve between the shaft and spool of the safe and reliable gas furnace plug valve of the utility model
Needle connects, and O-ring is cased with, and O-ring is closely fastened on valve by needle gasket under the spring-force driven dual of needle spring on needle
On core so that the sealing effect between needle and spool is more preferable, safe and reliable, and needle is inserted on spool, and the one of needle
End is fixedly connected with shaft so that the cooperation of needle and spool is not easy to loosen, durable, and shaft has preferable operation sense, dials
There is good contact performance between block and microswitch.The structure of this safe and reliable gas furnace plug valve is simple, dress
With conveniently, operability and leakproofness are preferable, safe and reliable, it is ensured that effective connection of microswitch, it is safe and reliable.
