Develop into a kind of main valve class；But the sealing ring and spool of ball valve easy to produce frictional dissipation in switching process；
A kind of ball valve as disclosed in 104121387 A of Chinese invention patent CN, the ball valve have：Shell, the shell shape
At entrance, outlet and obturator bearing；Obturator, the obturator formed inner cavity, the inner cavity have ingate, with enter
The opposite outlet opening of oral pore, the via hole between ingate and outlet opening simultaneously have the closing side opposite with via hole,
Wherein, entrance is connect by ingate and outlet opening with inner cavity, and ingate and outlet opening connect entrance and obturator bearing
It connects, and wherein external path is formed in the outer surface of closing side, when obturator is from closed position towards open position
When rotation, the external path is before outlet opening opens the second inner flow passage between inner cavity and outlet in obturator branch
The first outer flow channels are opened between seat and outlet；
Meeting during prolonged use of the ball valve of above-mentioned technology, spool and sealing ring can generate damage because of friction
Consumption, so as to cause leakage the problem of.
Invention content
One, technical problems to be solved
The purpose of the present invention is for the above problem present in the prior art, providing a kind of Leakproof ball valve, solve because
Ring wear and the problem of reveal.
Two, technical solution
In order to solve the above technical problems, the present invention provides a kind of Leakproof ball valve, including：Valve body, spool, the first sealing ring,
Second sealing ring, ring gasket, end cover, thrust spring and valve rod；
Spool, the first sealing ring, the second sealing ring, ring gasket, end cover, thrust spring and valve rod are mounted on valve
Internal portion；
First sealing ring and the second sealing ring and spool both sides are tangent；
Valve rod one end is embedded in spool, and the other end runs through valve body from valve inner；
End cover is fixed on valve end opening；
Thrust spring one end resists end cover, and the other end resists ring gasket and can axially push ring gasket.
Wherein, the first sealing ring embedding sealing steel ring.
Wherein, round sealing ring is arranged on ring gasket.
Wherein, round sealing ring is arranged on end cover.
Wherein, round sealing ring is rubber ring.
Wherein, the first sealing ring and the second sealing ring are that tetrafluoroethene material makes.
Wherein, end cover is equipped with Ka Gai, and Ka Gai is stuck in thrust spring one end inner ring.
Wherein, ring gasket is equipped with retainer ring, and retainer ring is stuck in thrust spring other end inner ring.
Three, beneficial effects of the present invention
Compared with prior art, Leakproof ball valve of the invention pushes the design of sealing ring by spring, makes up sealing ring and exists
Abrasion during use will not be revealed because of ring wear, have longer service life.

Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example cannot be used for limiting the scope of the invention for illustrating the present invention.
The structure of the Leakproof ball valve of the embodiment of the present invention includes as shown in figs. 1 and 3：Valve body 1, spool 2, the first sealing ring 3,
Second sealing ring 4, ring gasket 5, end cover 6, thrust spring 7 and valve rod 8；
Spool 2, the first sealing ring 3, the second sealing ring 4, ring gasket 5, end cover 6, thrust spring 7 and valve rod 8 are equal
It is installed on inside valve body 1；
First sealing ring, 3 embedding sealing steel ring 5；
Second sealing ring 4 is embedded in 1 inside one end of valve body；
First sealing ring 3 and the second sealing ring 4 and 2 both sides of spool are tangent；
8 one end of valve rod is embedded in spool 2, and the other end runs through valve body 1 from 1 inside of valve body；Rotary valve rod 8 controls spool 2 and revolves
Turn, is turned on and off to control ball valve；
End cover 6 is fixed on 1 open-ended place of valve body by clamp spring；
7 one end of thrust spring resists end cover 6, and the other end resists ring gasket 5 and can axially push ring gasket 5,
So that the first sealing ring 3 is adjacent to spool 2, and in the closed state of ball valve, can also further push spool 2 to be adjacent to the second sealing
