The beneficial effects of the utility model: first, sealing ring contacts the sealing realizing between valve seat and spheroid, spring one with spheroid
Can sealing ring be applied along certain pretightning force of valve seat axial direction, it is ensured that sealing effectiveness good, sealing ring can be reduced again
And the abrasion between spheroid.After sealing ring is worn, sealing ring can move to spheroid direction under the effect of spring one,
Support ring also moves to spheroid direction under the pretightning force that spring two applies, and makes sealing ring be in close contact with spheroid by double action and protects
Hold the sealing in valve body；After sealing ring lost efficacy, on bracing ring, metal sealing lip will contact with spheroid, in again ensureing valve body
Seal.Trumpet-shaped medial surface on bracing ring, is used for alleviating impulsive force and the pressure that valve seat is produced by the medium in medium channel,
Thus ensure the service life of valve seat；The baffle plate arranged between described spring one and sealing ring, makes baffle plate contact with the face of sealing ring
Replace the linear contact lay of original spring one and sealing ring, make valve seat stress equalization, keep better seal performance；Described bracing ring
And it is provided with O between valve body, it is ensured that the sealing between valve body and valve seat.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example
For the utility model is described, but it is not limited to scope of the present utility model.
As it is shown in figure 1, a kind of floating ball valve, including valve body 1, spheroid 2, valve seat 3 and valve rod 4, spheroid 2 is installed on valve body
In 1, valve rod 4 is connected with spheroid 2, and spheroid 2 two ends are provided with valve seat 3, and described valve seat 3 is arranged on valve body 1, and and spheroid
2 are in sealing contact.
As in figure 2 it is shown, described valve seat 3 includes bracing ring 31, sealing ring 32 and spring 1, described bracing ring 31 is near ball
The side of body 2 is provided with mounting groove 311, in described sealing ring 32 is arranged on mounting groove 311 and is in sealing contact with spheroid 2, described
Bracing ring 31 is provided with spring groove 312, is provided with spring 1 in spring groove 312, and sealing ring 32 can be applied by spring 1
Along the active force of valve seat 3 axial direction, both ensure that the good of sealing effectiveness in valve body 1, and spheroid 2 can have been discharged again and act on valve
Axial compressive force on seat 3, reduces the abrasion between sealing ring 32 and spheroid 2；Described bracing ring 31 is in sealing contact with valve body 1,
Form cavity 11 between described bracing ring 31 and valve body 1, in described cavity 11, be fixed with the spring 25 being in extended state,
Bracing ring 31 is applied to act as along valve seat 3 axial direction by described spring 25, and described bracing ring 31 is metal bracing ring 31,
