Abstract
The utility model provides a T-type three-way ball valve, which comprises a valve body, a valve stem and a valve core. The ball valve is characterized in that a pair of symmetrical lotus-shaped wholly-clasping type sealing seats matched with the valve core symmetrically closes above and below the spherical surface of the valve core; the mouth edge of every through orifice of the sealing seats for fit with the valve core is provided with a fixing ring which prevents an upper sealing seat and a lower sealing seat from rotating relatively; the periphery of the valve stem abutting against the upward side of the sealing seats is provided with a butterfly-shaped spring washer; the upward and downward sides of the spring washer are respectively provided with a flat gasket; and a compression nut is arranged above the flat gasket on the upper part so as to ensure that the sealing seats can always close the valve core and then play a reliable role in sealing. In a whole working process, the ball valve can realize complete sealing without leakage, allows gas-liquid transport and collection rate to reach 100 percent, and greatly improve equipment effectiveness.
Description
Technical field
The utility model relates to a kind of switching ball valve, especially a kind of T type tee ball valve, and this ball valve is widely used in industries such as oil, chemical industry, rock gas, power station, metallurgy, light industry, papermaking, refrigeration.
Background technique
At present, domestic ball valve is of a great variety, as: movable ball valve, fixing ball valve, internal thread ball valve, integral ball valve, threeway and four way ball valve or the like, the deficiency of these ball valves, be that seal degree is lower, bigger to the leakage rate of gas-liquid medium, can cause the certain loss of medium.
Summary of the invention
Technical problem to be solved in the utility model: be that a kind of good seal performance will be provided, flexible operation, gas-liquid transportation and collection rate can reach 100% T type tee ball valve.
For realizing that the technological scheme that above technical problem adopts is such: the utility model comprises valve body, valve rod and spool, be characterized at the upper and lower of being close to the spool sphere, the symmetry symmetrical lotus shape full-enclosed sealing seat that a pair of and spool are complementary of filling the span of a man's arms, and each openings position that sealing seat and spool are complementary, bead all is provided with the retainer ring that prevents that the upper-lower seal seat from producing relative rotation.In addition,, be provided with the butterfly spring packing ring,, respectively be provided with flat gasket, gland nut also is housed above the flat gasket on top at the upper and lower of butterfly spring packing ring near the valve rod periphery above the sealing seat.
Owing to adopt above technological scheme, produced beyond thought effect:
The utility model sealability is reliable, and flexible operation in entire work process, can be accomplished to seal ne-leakage fully, makes gas-liquid transportation and collection rate reach 100%, has greatly improved the benefit of equipment.

Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model is a kind of T type tee ball valve, it comprises valve body 5, valve rod 1 and spool 8, it is characterized in that at the upper and lower of being close to spool 8 spheres, the symmetry symmetrical lotus shape full-enclosed sealing seat 7 that a pair of and spool are complementary of filling the span of a man's arms, and each openings position that sealing seat and spool are complementary, bead all is provided with the retainer ring 6 that prevents that the upper-lower seal seat from producing relative rotation.
In Fig. 1, ball valve is in a kind of opening state, and valve body 5 adopts T type monolithic construction, forms through fine finishing with the blank of casting, and is higher to the vertical mesopore required precision of valve body, so that can intact equipment.The spool 8 of valve rod 1 and bottom thereof is housed in the vertical mesopore of valve body, symmetry lotus shape full-enclosed sealing seat is tightly filled the span of a man's arms the spool spheroid, involutory up and down later sealing seat 7, each openings that itself and spool 8 are complementary, at bead retainer ring 6 is set all, produces relative rotation to prevent upper and lower sealing seat.Near 1 periphery of the valve rod above the sealing seat 7, butterfly spring packing ring 4 is set,, flat gasket 3 is set respectively at the upper and lower of butterfly spring packing ring, gland nut 2 also is housed above the flat gasket on top, plays reliable seal action so that guarantee sealing seat can embrace spool 8 all the time.
