Specific embodiment
It should be noted that in the case of not conflicting, the embodiment in this utility model and the feature in embodiment can
To be mutually combined.
To describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in figure 1, the utility model proposes change-over valve core include being provided with the valve rod assembly of work sap cavity 16, and
The intermediate sleeve 4 being slidably socketed with valve rod assembly one end, the top stem casing 9 affixed with intermediate sleeve 4, and slip cap is located at top stem casing 9
Interior push rod component corresponding with valve rod assembly；
Wherein, to include being provided with valve rod 1, the swivel nut 2 being set on valve rod 1 corresponding with intermediate sleeve 4 position for described valve rod assembly
Sealing ring 3, be threaded connection between described valve rod 1 and swivel nut 2 and sealing ring 3 compressed, this three parts constitute one
Part, in valve rod 1, the entrance of the sap cavity 16 that works when sealing ring 3 is contacted with intermediate sleeve 4 is located at for described work sap cavity 16
Between set 4 in.
Described push rod component includes screw 5, push rod 10, sealing gasket 6；Described sealing gasket 6 is right with the valve rod 1 of valve rod assembly
Should, described screw 5 is threaded connection with push rod 10 and compresses sealing gasket 6, and this three parts constitute a part.
It is connected by jackscrew 7 between intermediate sleeve 4 and top stem casing 9.After being assembled as shown in Figure 1, reversing valve core is just changed into
One global facility, very convenient during installation and removal.
It is provided with piston bush 8, described piston bush 8 is slidably located in push rod 10 between wherein said push rod component and top stem casing 9
Go up and pass through the raised promotion push rod component on corresponding push rod 10 to slide to valve rod assembly；
