Description
Technical field
The present invention relates to a kind of valve part, be specifically related to a kind of ball valve core being applicable to Korrosionsmedium.
Background technology
Ball valve is that a class opening and closing element is driven by valve rod, and the valve rotated around ball valve axis, also can be used for fluid
Regulation and control.The ball valve being currently known mainly includes valve body, valve rod, spheroid and sealing ring, tight by spheroid and sealing ring
Contiguity touches the sealing realizing ball valve, and spinning ball is to realize the opening and closing of valve.The opening and closing element of ball valve is spheroid, current spheroid master
Will be made up of metals such as carbon steels, when being applied to have corrosive liquid or gas transmission by ball valve, spheroid is in life-time service
Easily it is corroded, affects the sealing effectiveness of ball valve.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of ball valve core being applicable to Korrosionsmedium, this ball valve core
There is the strongest corrosion resistance, effectively extend ball valve service life, make ball valve be more suitable for the transmission of acrid medium.
The present invention is achieved through the following technical solutions:
A kind of ball valve core being applicable to Korrosionsmedium, including sphere body, described sphere body includes valve casing and channel cylinder,
Described valve casing is hollow ball, and its welded top has the valve rod union joint of cylinder, and described valve rod union joint top is provided with valve rod
Connecting hole.The valve casing left and right sides is respectively provided with a diameter circular hole equal with channel cylinder internal diameter, channel cylinder be arranged in valve casing and
Its two ends are connected with valve casing left and right circular hole respectively, are fixed with several ribs between described valve casing inwall and channel cylinder outer wall, described
With one layer of overcoat on valve casing outer wall and channel cylinder inwall.
Described valve casing, ribs and channel cylinder are made by carbon steel.
Described overcoat material is cobalt carbide or politef.Cobalt carbide and politef have the highest corrosion-resistant
Property, overcoat uses cobalt carbide or politef, it is possible to effectively protection valve casing and channel cylinder not being corroded property fluid media (medium) is rotten
Erosion, makes ball valve core more can be suitably used for Korrosionsmedium, extends ball valve core service life.
Described valve casing and channel cylinder are by being weldingly connected.Owing to having overcoat on valve casing outer wall and channel cylinder inwall, because of
Even if this valve casing and channel cylinder are by being weldingly connected, overcoat is also avoided that valve casing and channel cylinder weld part are by gas or corrosivity
Flow-induced corrosion, destroys valve casing and the connection of channel cylinder.
The present invention compared with prior art, has such advantages as and beneficial effect:
(1) present invention is by having overcoat, when Korrosionsmedium flows through ball valve on valve casing outer wall and channel cylinder inwall, it is possible to
Avoid sphere body by dielectric corrosion, substantially increase ball valve service life in Korrosionsmedium transmits；
(2) sphere body is designed as hollow-core construction by the present invention, has saved raw material, reduces ball valve manufacturing cost, simultaneously at valve
It is provided with ribs between shell and channel cylinder, increases the intensity of sphere body, it is to avoid deform after sphere body life-time service.

Embodiment
As shown in Figure 1, 2, a kind of ball valve core being applicable to Korrosionsmedium, including sphere body 1, described sphere body
1 includes valve casing 2 and channel cylinder 3, and described valve casing 2 is hollow ball, and its welded top has the valve rod union joint 4 of cylinder, described
Valve rod union joint 4 top is provided with valve rod connecting hole 41.It is equal with channel cylinder 3 internal diameter that valve casing 2 left and right sides is respectively provided with a diameter
Circular hole 21, in channel cylinder 3 is arranged at valve casing 2 and its two ends are connected with valve casing about 2 circular hole 21 respectively, described valve casing 2 inwall
And it is fixed with between channel cylinder 3 outer wall on several ribs 5, described valve casing 2 outer wall and channel cylinder 3 inwall with one layer of overcoat 6.
Described valve casing 2, ribs 5 and channel cylinder 3 are made by carbon steel.
Described overcoat 6 material is cobalt carbide or politef.
Described valve casing 2 and channel cylinder 3 are by being weldingly connected.
During use, ball valve core of the present invention is installed in ball valve, utilizes valve rod union joint 4 that valve rod one end is fixed on valve
In lever attachment hole 41, owing to one layer of overcoat 6 is adhered in valve casing 2 and channel cylinder 3 periphery, therefore ball valve core of the present invention is used
When corrosive fluid medium transmits, spool is it can be avoided that by dielectric corrosion.It is greatly prolonged ball valve in Korrosionsmedium transmits
Service life, reduce fluid transmission cost.
Above-described detailed description of the invention, has been carried out the purpose of the present invention, technical scheme and beneficial effect further
Describe in detail, be it should be understood that the detailed description of the invention that the foregoing is only the present invention, be not intended to limit the present invention
