Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of Dual positioning ball valve, as shown in Figure 1 and Figure 2, including valve body 1 and the sphere being set in valve body 1 11, valve
Body 1 includes left valve barrel 12, center valve body 13 and the right valve barrel 14 being successively welded and fixed, wherein 13 upper and lower ends of center valve body
It is relatively set with upper ball base 15 and lower ball base 16,11 upper and lower ends of sphere, which are polished respectively and polished, forms upper horizontal plane 17 under
Horizontal plane 18, upper horizontal plane 17 fit in upper ball base 15, and lower horizontal plane 18 fits in lower ball base 16, and upper horizontal plane 17 is integrally formed
There is a upper cylinder 19, for lower horizontal plane 18 integrally formed with lower cylinder 20, upper ball base 15 and lower ball base 16 are vertical through offering respectively
The through-hole 21 being rotatably assorted with upper cylinder 19, lower cylinder 20.
The utility model is directed at the through-hole 21 of upper ball base 15 and upper cylinder 19 and is inserted into, up to upper ball base 15 in assembly
Lower surface and upper horizontal plane 17 be in face paste conjunction state, to complete the connection of upper ball base 15 Yu sphere 11, and with identical
Mode connects lower ball base 16 and sphere 11；After completing the connection of sphere 11 and upper ball base 15, lower ball base 16, by sphere 11 together with
Upper ball base 15 and lower ball base 16 are embedded in center valve body 13, and left valve barrel 12 and right valve barrel 14 is forced to be connected to center valve body respectively
Left valve barrel 12, center valve body 13 and right valve barrel 14 are finally fixed, to complete the dress of ball valve in 13 both ends in a welding manner
Match；After ball valve is completed to assemble, upper ball base 15 and lower ball base 16 are limited in valve body 1 by left valve barrel 12 and the clamping of right valve barrel 14,
To realize that upper ball base 15 and stablizing for lower ball base 16 are installed, simultaneously because the upper horizontal plane 17 and lower horizontal plane 18 of sphere 11 divide
It is not bonded with upper ball base 15 and 16 surface of lower ball base, to be completed by upper ball base 15 and lower ball base 16 to 11 vertical direction of sphere
Limitation, simultaneously because the upper cylinder 19 of sphere 11 and lower cylinder 20 are plugged in respectively in respective through hole 21, to realize to sphere
The limitation of 11 horizontal directions, in conjunction with the above two o'clock, so that sphere 11 only has using vertical axis as the activity of center of rotation rotation
Degree, and then sphere 11 is prevented to be displaced, effectively improve the non-overflow performance of ball valve.
Left valve barrel 12 and right valve barrel 14 clamp upper ball base 15 and lower ball base 16 in the following way, as shown in Figure 3, Figure 4, left
The inner cavity of valve body 12 and 14 opposite end of right valve barrel respectively integrally formed with push against ring along 22, two abutting rings along 22 push against respectively in
The both ends of upper ball base 15 and lower ball base 16, thus by two abutting rings along 22 symmetrical clamping upper ball bases 15 and lower ball base
16, and then realize that upper ball base 15 and lower ball base 16 stablize the technical requirements being installed on inside valve body 1.
In the design of the utility model, need that sealing ring, the sealing is arranged in the inner cavity of left valve barrel 12 and right valve barrel 14
Ring needs are fitted closely in the spherical surface of sphere 11, therefore left valve barrel 12, right valve barrel 14 and the relative position of sphere 11 are most important,
Thus as shown in Figure 3, Figure 4, pin shaft 23 has been plugged and fixed in the both ends of upper ball base 15 and lower ball base 16 respectively, pushes against ring and opens up along 22
There is the pin shaft hole 24 being inserted into for pin shaft 23, to pass through mating, the realization left valve barrel 12, right valve of pin shaft 23 and pin shaft hole 24
The positioning of body 14 and upper ball base 15, lower ball base 16, but because upper ball base 15, lower ball base 6 and sphere 11 have constant position and close
System is finally reached the technical effect of positioning ball 11 and left valve barrel 12, right valve barrel 14.
For further positioning ball 11 and left valve barrel 12, right valve barrel 14, as shown in Figure 3, Figure 4, upper ball base 15 and lower ball base
Respectively integrally formed with circular arc positioning surface 25, the circular arc positioning surface 25 at both ends fits in left valve barrel 12 and right valve barrel 14 at 16 both ends
Intrados is realized to be closed by the face paste of circular arc positioning surface 25 and left valve barrel 12, right valve barrel 14 for upper ball base 15 and lower ball
The further positioning of seat 16, in conjunction with mating, the final technology for realizing Dual positioning sphere 11 of pin shaft 23 and pin shaft hole 24
Effect.
Ball valve realizes opening and closing by the rotation of sphere 11, for the rotation smoothness for improving sphere 11, as shown in Fig. 2, upper water
Pad is equipped with smooth gasket 26 between plane 17 and upper ball base 15, and pad sets smooth gasket 26 between lower horizontal plane 18 and lower ball base 16,
To utilize the lower characteristic of smooth 26 skin-friction coefficient of gasket, frictional force suffered when sphere 11 rotates is effectively reduced,
And then improve the rotation smoothness of sphere 11.
It is found in practice, since ball valve has certain weight, to avoid the weight of ball valve from acting on pipe completely
On road, as shown in figure 3, left valve barrel 12 and right valve barrel 14 are welded with support plate 27, so that ball valve passes through support plate 27
Realization is supported with ground, and then the weight of ball valve is avoided to act on pipeline completely；Meanwhile 27 downside one of support plate
Level board 28 is formed, level board 28 offers threaded hole 29, so as to realize the company of support plate 27 and ground by bolt
It connects, and then improves the mounting stability of ball valve.
Specific embodiment is only the explanation to the utility model, is not limitations of the present invention, this field
Technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but only
It will be in the scope of the claims of the utility model all by the protection of Patent Law.
