The utility model discloses flow stopping body medium be can prevent and reliability and security that the reinforcing ball valve used are revealed to the atmosphere to the second is sealed to be filled up and the sealed adoption special design that fills up of third, has prolonged the life of ball valve, has improved job stabilization nature.
Description
Technical field
The utility model is related to valve body field, particularly to a kind of ball valve.
Background technology
Ball valve, as a kind of conventional valve body, is widely used in the industries such as oil, chemical industry, natural gas, electric power, metallurgy.
Most ball valve is provided with the valve seat matching with spheroid valve in valve body, and spheroid valve slides on valve seat wall and to realize closing
Play ball valve, such spheroid valve produces sliding friction with valve base chamber, and ball valve, through a period of time, spheroid valve serious wear, is easily led
Cause gas leakage, oil leakage phenomenon.Sealing between ball-valve valve rod and valve body is poor simultaneously, once using aged deterioration, also results in
Fluid media (medium) flows out, and causes potential safety hazard.
Therefore, special proposition the utility model.
Utility model content
The utility model provides a kind of high-air-tightness ball valve, the air-tightness of comprehensive enhancing ball valve, and this ball valve has in no
The advantage of leakage, no abrasion and high sealing reliability.
A kind of high-air-tightness ball valve, including valve body, handle, valve rod, spheroid and valve seat, described valve body is provided with and supplies sphere installation
Valve pocket, be provided with sealing metal part, the lower section of sealing metal part between described valve rod and valve body, be close at valve body upper surface
It is provided with the first sealing gasket；It is provided with the second sealing gasket between valve seat and spheroid；Second sealing gasket is provided with wearing layer；Valve seat and valve body
Between be provided with the 3rd sealing gasket；Described 3rd sealing gasket carries raised platforms, the 3rd sealing gasket be filled in valve seat and valve body it
Between space in；Described valve seat is provided with several grooves, and the second sealing gasket is provided with matched bossing, and second is close
The bossing of packing is filled in the groove of valve seat.
The utility model provide high-air-tightness ball valve, by using specific structure setting, can prevent fluid media (medium) to
Air is revealed, and strengthens reliability and the security that ball valve uses, and the second sealing gasket and the 3rd sealing gasket adopt particular design,
Extend the service life of ball valve, improve the stability of work.

Specific embodiment
As shown in figure 1, a kind of high-air-tightness ball valve, including valve body 1, handle 6, valve rod 7, spheroid 4 and valve seat 3, described valve
Body 1 is provided with the valve pocket 2 for sphere installation, is provided with sealing metal part 5, sealing metal part 5 between described valve rod 7 and valve body 1
Effectively fluid media (medium) can be isolated, will not leak.For further enhancing its air-tightness, the lower section of sealing metal part 5, it is close to
It is provided with the first sealing gasket 8 at valve body 1 upper surface.First sealing gasket 8 guarantees fluid media (medium), particularly has corrosive medium and lets out
Reveal to sealing metal part 5, to avoid sealing metal part 5 being corroded property dielectric breakdown, and affect the air-tightness of ball valve.
With reference to Fig. 2, between valve seat 3 and spheroid 4, it is provided with the second sealing gasket 10.Second sealing gasket 10 is fitted with spheroid 4 surface,
Air-tightness can effectively be strengthened.Second sealing gasket 10 surface is provided with wearing layer (not shown), does not rotate because spheroid is long-term and rubs
Wiping the second sealing gasket 10 leads to air-tightness to reduce, and extends the service life of ball valve.Second sealing gasket 10 bottom has some projections,
It is filled in the groove of corresponding valve body 1 so that the second sealing gasket 10 can be securely arranged on valve body 1, difficult for drop-off, extend
The service life of ball valve.
It is provided with the 3rd sealing gasket 9 between valve seat 3 and valve body 1.Described 3rd sealing gasket 9 carries raised platforms, and the 3rd is close
Packing 9 is filled in the space between valve seat and valve body.3rd sealing gasket 9 enhances the air-tightness between valve seat 3 and valve body 1,
Being arranged on valve body 1 of 3rd sealing gasket 9 clamp-close type also ensure that it is difficult for drop-off simultaneously, extends the service life of product.
Above a kind of high-air-tightness ball valve provided by the utility model is described in detail.Tool used herein
Body example is set forth to principle of the present utility model and embodiment, and the explanation of above example is only intended to help understand
Core concept of the present utility model.It should be pointed out that for those skilled in the art, without departing from this practicality
On the premise of new principle, the utility model can also be carried out with some improvement and modify, these improve and modification also falls into this
In the protection domain that utility model right requires.
