In the annular groove of the described valve body of described steam inlet pipe joint inserting upper end and the interface of the two be provided with seal ring, the outside of described steam inlet pipe joint also forms buckle, buckle snaps onto on the outer shoulder of described valve body outer side wall.
The top of described cam ramp forms the limiting stopper that exceeds described cam ramp, and is excessive to prevent the knob rotation.
Described cam ramp is the plane near a bit of of described limiting stopper, is held open state so that knob is opened the back oneself.
Also form the pin that is used to install on the described outer side of valve body.
Compared with prior art, advantage of the present utility model is: sealability is good, rational in infrastructure and be convenient to adopt the plastic material moulding to make, solved because of the not good situation that causes steam valve sealability deficiency of copper material three-way pipe sealing, effectively reduced cost of material and manufacture cost.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one
As Fig. 1～illustrated in Figure 8, be a preferred embodiment of the present utility model.As Fig. 1～shown in Figure 8, the steam valve of present embodiment coffee machine, it has a valve body 1 that is three-port structure, is provided with axial reach through hole 2 in the valve body 1, and valve body 1 sidewall is provided with the steam (vapor) outlet 3 that connects with reach through hole 2 stage casings.Be provided with mangetic core assembly in the reach through hole 2, the upper end of valve body 1 is sealedly connected with steam inlet pipe joint 4.In the annular groove of described steam inlet pipe joint 4 inserting valve bodies 1 upper end and the interface of the two be provided with seal ring 5, the outside of steam inlet pipe joint 4 also forms buckle 6, buckle 6 snaps onto on the outer shoulder of valve body 1 outer side wall.Described mangetic core assembly comprises valve rod 7, valve stem packing ring 8 and pressure spring 9, the middle part of valve rod 7 has the bulge loop 71 that outside protrusion forms, valve stem packing ring 8 is enclosed within on the valve rod 7 and is positioned at the below of bulge loop 71, the epimere of reach through hole 2 has to the adaptive annular valve port 21 of projecting inward that form and bulge loop 71, pressure spring 9 is against the upper-end surface of bulge loop 71 and valve rod 7 is had all the time move downward sealing the trend of annular valve port 21, and the lower end of valve rod 7 supports also that be provided with can be with the opening/closing mechanism of valve rod 7 jack-up.
