Inlet 11 and liquid outlet 12) and spheroid 2 between, including mutually seal with spheroid 2 and be located at spheroid 2 side (near feed liquor
Mouthfuls 11 side) the first valve seat 31 mutually seal with spheroid 2 and is located at spheroid 2 opposite side (side of close liquid outlet 12)
Second valve seat 33 and be arranged between valve body 1 and the first valve seat 31 and be used for propping up the spring 32 of the first sealing clamping ring 31, so
Only formed single track sealing so that the sealing of floating ball valve there is a problem of certain.
Content of the invention
The utility model purpose is to overcome the deficiencies in the prior art to provide a kind of the close of metal sealing floating ball valve
Seal structure.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is：A kind of sealing of metal sealing floating ball valve
Structure, it is arranged between valve body and spheroid, and described valve body has the inlet being connected and liquid outlet, and described spheroid is rotatable
Be arranged in described valve body, it includes contacting with described spheroid and first valve seat corresponding with described inlet and institute
State spheroid contact and second valve seat corresponding with described liquid outlet, be arranged at described first valve seat side trim ring, card set
Carbon seal ring between described trim ring and described first valve seat and be arranged between valve body and described trim ring and be used for propping up
The spring of described trim ring.
Optimally, the side of described first valve seat forms bulge loop, is formed for accommodating between described bulge loop and described valve body
The accommodation space of described carbon seal ring.
Further, the lateral surface of described carbon seal ring forms scrobicular ring, and the side of described trim ring is respectively formed with and institute
State groove and the projection fastening with described scrobicular ring that bulge loop fastens.
Because technique scheme is used, the utility model compared with prior art has following advantages：The utility model
The sealing structure of metal sealing floating ball valve, by arranging trim ring in the side of the first valve seat, and trim ring and the first valve seat it
Between setting carbon seal ring, be so capable of between trim ring and carbon seal ring and carbon seal ring and the first valve seat it
Between two seals, solve the problems, such as single track sealing metal seal floating ball valve difficult sealing.

Specific embodiment
Shown embodiment is further described to the utility model below in conjunction with the accompanying drawings.
The sealing structure 3 ' of metal sealing floating ball valve as shown in Figure 2, it include the first valve seat 31 ', spring 32 ',
Two valve seats 33 ' and trim ring 35 '.This sealing structure is arranged between valve body 1 ' and spheroid 2 ', and this valve body 1 ' has entering of being connected
Liquid mouth 11 ' and liquid outlet 12 ', it is interior that spheroid 2 ' is then installed in rotation on valve body 1 '.
Wherein, the first valve seat 31 ' is contacted with spheroid 2 ' and corresponding with inlet 11 ', the second valve seat 33 ' and spheroid 2 '
Contact and corresponding with liquid outlet 12 ', the first valve seat 31 ' and the second valve seat 33 ' are contacted with spheroid 2 ', respectively thus realizing
Sealing between them.Trim ring 35 ' is arranged on the lateral surface of the first valve seat 31 ', and carbon seal ring 36 ' is fastened on trim ring 35 '
With first between valve seat 31 ', it has been achieved in that between carbon seal ring 36 ' and trim ring 35 ', carbon seal ring 36 ' and the first valve
Two seals between seat 31 '.Spring 32 ' is arranged between valve body 1 ' and trim ring 35 ', is used for propping up trim ring 35 ' and ensures
State two seals.
In the present embodiment, the lateral surface of the first valve seat 31 ' forms bulge loop 311 ', surrounds between bulge loop 311 ' and valve body 1 '
For accommodating the accommodation space 312 ' of carbon seal ring 36 '.The lateral surface (left surface) of carbon seal ring 36 ' forms scrobicular ring
361 ', the medial surface (right flank) of trim ring 35 ' is respectively formed with the groove 351 ' fastening with bulge loop 311 ' and and scrobicular ring
361 ' the projections 352 ' fastening, so can improve between carbon seal ring 36 ' and trim ring 35 ', carbon seal ring 36 ' and
Seal degree between one valve seat 31 '.
