Specific embodiment
Below in conjunction with the accompanying drawings this utility model embodiment is described further：
As illustrated, a kind of good ball valve of valve base seal property, including left valve barrel 1, right valve barrel 2, spheroid 3, valve rod 4, a left side
Valve seat 5, right valve seat 6；Described left valve barrel 1 is provided with intake channel 11, and described right valve barrel 2 is provided with exit passageway 21, and described spheroid 3 sets
Put between left valve barrel 1 and right valve barrel 2；Described valve rod 4 is connected through left valve barrel 1 with spheroid 3；Described right valve seat 6 is installed
In right valve barrel 2, and it is fixed by an annular pressing plate 8；In described right valve barrel 2, heap is welded with one layer of hard alloy sealant
22, and one end sealing cooperation with right valve barrel 2；The other end of described right valve seat 6 then seals cooperation with spheroid 3；
Right valve seat 6 is pressed abd fixed on right valve barrel 2 by annular pressing plate 8, and close by pile-up welding hard alloy on right valve barrel 2
Sealing 22 is sealed with right valve seat 6, and the fixation not only ensureing right valve seat 6, so as to not affected by buffer brake, in turn ensure that sealing effect
Really, and achieve detachable, be easy to safeguard.
Wherein, the bolt 9 that described annular pressing plate 8 is evenly arranged by some circumferences is fixed on right valve barrel 2, installation side
Just, and make its uniform force, install reliable.
As illustrated, described left valve seat 5 is arranged in left valve barrel 1, its one end is coordinated with spheroid 3 sealing；Described left valve barrel 1
End face with the cooperation of left valve seat 5 is in stepped ramp type structure, and including first step 12, second step 13, described first step 12 is arranged
In second step 13 outer ring, and offset with left valve seat 5, between described second step 13 and left valve seat 5, be provided with disc spring 7.
