The utility model can also be able to further realization through following measure simultaneously:
Described elastic sealing device comprises valve seat, high-temperature gasket, high temperature valve seat and the seating spring that sets gradually to valve gap from spheroid.
Be provided with gasket seal between described upper valve rod seat and valve body and upper valve rod seat and the adapter.
Described valve gap is provided with the spring seat of groove-like towards an end of spheroid, and said seating spring is embedded in spring seat.
Be provided with the first high temperature filler between described upper valve rod seat and the upper valve rod, the upside of the first high temperature filler is provided with first hold-down grid, first hold-down grid through bolt or screw in upper valve rod seat upper end.
Be provided with the second high temperature filler between described adapter and the upper valve rod, the upside of the second high temperature filler is provided with second hold-down grid, and second hold-down grid is being taken over the upper end through bolt or screw.
The beneficial effect of the utility model is:
1), the elastic sealing device in the utility model is that valve provides excellent temperature difference dynamic compensation effect, thereby no matter guaranteed that ball valve can both keep excellent sealing performance when temperature raises or reduce.
2), the utility model is provided with gasket seal at upper valve rod seat and valve body and upper valve rod seat and between taking over; Between upper valve rod seat and upper valve rod, be provided with simultaneously the first high temperature filler; And between adapter and upper valve rod, be provided with the second high temperature filler; Thereby the sealing position that has guaranteed upper valve rod keeps excellent sealing performance in the elevating movement process, more effectively be applicable to high temperature and high pressure condition.
