The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1-5, this steam converting valve of coffee machine, comprise steam valve body 1 and steam knob 6, steam valve body is a triple valve, steam valve body 1 sidewall is provided with installing plate 1.6, be provided with axial reach through hole in the steam valve body, steam valve body 1 is provided with steam inlet 1.4, and a side of steam inlet is provided with steam (vapor) outlet 1.3, and steam converting valve also comprises steam regulating shaft 5, one end of steam regulating shaft cooperates fixing with steam valve body 1, the other end of steam regulating shaft 5 and steam knob 6 socket-connect, and steam valve body 1 is provided with chute 1.1, and the chute outer wall is provided with chute projection 1.2, steam regulating shaft 5 is provided with pilot hole 5.3, and locating shaft 4 interts in chute 1.1 and pilot hole 5.3.One end of steam regulating shaft 5 is provided with plug 5.4, and steam knob 6 is provided with sleeve; Plug cover is connected in the sleeve.The cross section of plug 5.3 and sleeve is triangular in shape.Steam regulating shaft 5 is moving linearly in steam valve body 1, and steam regulating shaft 5 drive sealing gaskets 2 closely cooperate with convex tendon 1.5 and separate, and realization steam inlet 1.4 is opened and closed with steam (vapor) outlet 1.4.
