Description
Technical field
The utility model relates to ball valve field more particularly to a kind of wear-resisting accurate adjustment ball valves of square hole runner.
Background technique
Existing ball valve generally comprises valve body, valve deck, valve rod, sphere, spring, valve seat；Sphere and valve seat have round hole
Runner.Valve rod and sphere mechanical bond, sealing element are sphere and valve seat, and sphere and valve seat are at mating spherical surfaces, and sphere is with valve rod
90 ° of rotations can be done in valve body for shaft, valve channel is opened and closed with this, to prevent the flowing of channel media, spring
Elastic force make sphere be close to be sealed with sealing surface of seat.
The shortcoming of existing this ball valve is:
One, when small guide vane when valve during opening or closing, sphere and valve seat cooperatively form oval mouth runner, face
Product is small, and negotiability is also small, and flow velocity increases, and the ball mouth of sphere and the valve seat mouth of valve seat are easy by fluid media (medium) erosion failure.
Two, since valve seat mouth is circle, sphere overcurrent mouth is also circle, then the oval cross section formed in switching process is
Non-linear cross-section, thus fluid is needed to reach required precision when linear regulation.
Three, the angle of valve closing passage is at 70~90 °, and switch angle is big, and the time is long, and thus medium is to sealing surface of seat
And the flushing time of sphere is long, to keep the service life of valve short.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides a kind of reduction sphere runner and rushing of being subject to of valve seat runner
The small rectangular runner to reduce flushing time of sphere rotational angle wear-resisting accurate adjustment ball valve when brush, linear regulation aperture, switch, solution
Existing ball valve of having determined washed away it is serious and can not linear regulation aperture the problem of.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of wear-resisting accurate adjustment ball valve of square hole runner, including valve body are equipped with valve seat in valve body, are arranged with ball in valve seat

It is square hole, the square hole of sphere and valve seat is horizontally disposed.
As a preferred embodiment of the present invention, the valve seat is sealing surface close to the arc of sphere, and sealing surface is close to valve
One section of setting of the runner hole of seat is jagged, and one section of runner hole of the sealing surface far from valve seat is in close contact with sphere.
As a preferred embodiment of the present invention, filled in valve body in the region that the valve body, sphere, valve seat surround
Lining.
As a preferred embodiment of the present invention, between the valve seat and valve body setting there are three seal chamber, two sides it is close
Seal it is intracavitary be provided with sealing ring, be provided with disc spring in the seal chamber at middle part.
As a preferred embodiment of the present invention, the corner of the runner hole of the corner and valve seat of the runner hole of the sphere
Place is provided with rounding.
As a preferred embodiment of the present invention, the valve body includes valve body and valve deck, and valve seat is installed on valve body master
In the space that body and valve deck surround, valve body and valve deck are bolted.
As a preferred embodiment of the present invention, packing cavity is provided between the valve body and valve rod, in packing cavity
Also it is arranged with the gland for compressing packing box assembly filled with packing box assembly, in packing cavity, the one of gland
End is contacted with packing box assembly, and the other end of gland is connected with hold-down grid, passes through between hold-down grid and valve body
It is bolted.
Compared with prior art, the utility model has the beneficial effects that
1, due to being provided with square hole in sphere and valve seat, then when valve opens or closes small guide vane, sphere and valve
Seat cooperatively forms rectangle runner mouth-shaped, and the oval open area formed when relative to existing ball valve small guide vane greatly increases, from
And the ability of runner is increased, velocity of medium is reduced, reducing fluid rushes damage to ball mouth and valve seat mouth, extends it and uses the longevity
Life.
2, the aperture for the rectangle runner open area and valve that sphere and valve seat cooperatively form is linear, to make to be situated between
Mass flow cross valve flow and aperture it is also linear so that valve have accurate linear characteristic regulatory function.
3, due to being provided with square hole in sphere and valve seat, then square hole angle shared on sphere or valve seat compared with
Small, switch angle is reduced to 50~55 °.Therefore, the valve switch time is reduced, and medium is in switching process to sphere mouth and valve seat
The flushing time of mouth greatly reduces, and the service life of valve can be improved.
4, due to the concealed design of valve base sealing mouth, thus make valve in switch 50% or so medium still not to valve seat
Seal and formed punching damage, correspondinglyd increase the service life of sealing surface of seat.
5, valve body liner is filled in the region that valve body, sphere, valve seat surround, valve body liner can prevent valve from switching
Medium enters the case where spherome surface and valve chamber are damaged in punching in valve chamber in journey, helps to improve ball valve service life.
6, sphere can be close to by the disc spring between valve seat and valve body with sealing surface of seat, guarantee sealing.Disc spring two sides it is close
Envelope chamber is respectively provided with sealing ring, guarantees reliable sealing.
7, the corner of the runner hole of the corner and valve seat of the runner hole of sphere is provided with rounding, reduces fluid other side
Cause the case where excessively washing away in the corner in shape hole.
8, valve body and valve deck are bolted, and facilitate the installation of valve seat.
9, after gland compresses packing box assembly, packing box assembly can make to be formed between valve rod and valve body reliable
Sealing.
