Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of metal hard-sealing threeway from valve-control spherical, has improved sealing and wear resistance, has reduced the leakage of valve seat, has extended working life.
The technological scheme providing according to the utility model, metal hard-sealing threeway comprises valve body cap, spheroid, valve body and valve rod from valve-control spherical, and valve body front end is bolted valve body cap, and valve body and valve body cap inside are provided with valve seat, roll spheroid is installed in valve seat; In valve body cap, be provided with the first outlet, valve rear end and lower end are respectively equipped with the second outlet and import, spheroid is positioned on the passage that connects the first outlet, the second outlet and import, it is characterized in that: between described valve body cap and valve seat, be provided with the first butterfly spring, the first butterfly spring is positioned at the first outlet and is communicated with spheroid end; Between valve body and valve seat, be provided with the second butterfly spring, the second butterfly spring is positioned at the second outlet and is communicated with spheroid end; By bearing, valve rod is installed in valve body, valve body is stretched out in valve rod one end, the other end spheroid that is spirally connected; Between described valve rod and valve body, be provided with balance filler, balance filler is positioned at bearing upper and lower end.
Further, in spheroid, be provided with L shaped passage.
The outlet end bonding pad gland of valve rod further, is installed at valve body.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, adopts butterfly spring to do dynamic seal (packing) compensation, and the flow direction of degree of reaching high-temperature high-pressure medium is switched, and has improved sealing; Adopt filler to improve sealing and wear resistance, extended working life.

Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the utility model mainly comprises valve body cap 1, spheroid 4, valve body 5 and valve rod 8, and valve body 5 front ends are bolted valve body cap 1, and valve body 5 and valve body cap 1 inside are provided with valve seat 3, and spheroid 4 is installed in the interior rolling of valve seat 3, is provided with L shaped passage in spheroid 4.
In valve body cap 1, be provided with the first outlet 11, valve body 5 rear ends and lower end are respectively equipped with the second outlet 12 and import 13.Spheroid 4 is positioned on the passage that connects first outlet the 11, second outlet 12 and import 13.
Between described valve body cap 1 and valve seat 3, be provided with the first butterfly spring 2, the first butterfly springs 2 and be positioned at the first outlet 11 connection spheroid 4 ends.Between valve body 5 and valve seat 3, be provided with the second butterfly spring 7, the second butterfly springs 7 and be positioned at the second outlet 12 connection spheroid 4 ends.
In valve body 5, by bearing 10, valve rods 8 are installed, valve body 5 is stretched out in valve rod 8 one end, the other end spheroid 4 that is spirally connected.Between described valve rod 8 and valve body 5, be provided with balance filler 9, balance filler 9 is positioned at bearing 10 upper and lower end.The outlet end bonding pad gland 6 of valve rod 8 is installed at valve body 5, is prevented that balance filler 9 from departing from.
