Abstract
The utility model discloses a case that wearability is good, including the spheroid body, the spheroid body includes a valve casing and a runner section of thick bamboo, the valve casing is hollow sphere, and weld at its top has columniform valve rod connector, valve rod connector top is equipped with the valve rod connecting hole. The valve casing each side is equipped with the round hole that a diameter and runner section of thick bamboo internal diameter equal, a runner section of thick bamboo set up in the valve casing and its both ends respectively with the valve casing about the round hole link to each other, be fixed with the several stiffening rib between valve casing inner wall and runner section of thick bamboo outer wall, with the one deck inoxidizing coating on valve casing outer wall and the runner section of thick bamboo inner wall. This case has very strong wearability, effectively prolongs ball valve life, makes the ball valve more be applicable to the transmission of taking particulate medium.
Description
Technical field
This utility model is related to a kind of valve part and in particular to a kind of good valve element of wearability.
Background technology
Ball valve is that a class opening and closing element is driven by valve rod, and the valve rotating 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 to realize 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
To be made up of metals such as carbon steels, when ball valve is applied to the liquid with granule or gas transmission, spheroid is easy in life-time service
By fluid erosion, ball for ball valve sealing is led to reduce, the using effect of impact ball valve.
Content of the invention
In order to solve the above problems, this utility model provides a kind of wearability good valve element, and this valve element has very strong resistance to
Mill property, effectively extends ball valve service life, makes ball valve be more suitable for the transmission with granule medium.
This utility model is achieved through the following technical solutions：
A kind of good valve element of wearability, including sphere body, described sphere body includes valve casing and channel cylinder, described valve casing
For hollow ball, its welded top has the valve rod union joint of cylinder, and described valve rod connects head and is provided with valve rod connecting hole.Valve
The shell left and right sides is respectively provided with a diameter circular hole equal with channel cylinder internal diameter, and channel cylinder is arranged in valve casing and its two ends difference
Be connected with circular hole about valve casing, between described valve casing inwall and runner drum outer wall, be fixed with several ribs, described valve casing outer wall and
One layer of overcoat is had on channel cylinder inwall.
Described valve casing, ribs and channel cylinder are made by carbon steel.
Described overcoat material is cobalt carbide.Cobalt carbide has very high intensity, and overcoat adopts cobalt carbide, can be effective
Protect valve casing and channel cylinder not to be corroded by the fluid media (medium) with granule, make valve element more can be suitably used for medium, extending valve element makes
Use the life-span.
Described valve casing and channel cylinder pass through to be weldingly connected.Due to overcoat being had on valve casing outer wall and channel cylinder inwall, because
Even if this valve casing and channel cylinder pass through to be weldingly connected, overcoat is also avoided that valve casing and channel cylinder weld part by the fluid with granule
Corrode, destroy the connection of valve casing and channel cylinder.
This utility model compared with prior art, has such advantages as and beneficial effect：
（1）This utility model passes through to have overcoat on valve casing outer wall and channel cylinder inwall, and the medium with granule flows through
During ball valve, it can be avoided that sphere body is by erosion medium resistance, substantially increase service life in medium transmission for the ball valve；
（2）Sphere body is designed as hollow-core construction by this utility model, has saved raw material, reduces ball valve manufacturing cost,
It is provided with ribs simultaneously between valve casing and channel cylinder, increases the intensity of sphere body, it is to avoid deform after sphere body life-time service.
Brief description
Accompanying drawing described herein is used for providing this utility model embodiment is further understood, and constitutes the one of the application
Part, does not constitute the restriction to this utility model embodiment.In the accompanying drawings：
Fig. 1 is this utility model along channel cylinder radial cross-section；
Fig. 2 is this utility model along channel cylinder axial sectional view；
Labelling and corresponding parts title in accompanying drawing：
1- sphere body, 2- valve casing, 21- circular hole, 3- channel cylinder, 4- valve rod union joint, 41- valve rod connecting hole, 5- strengthens

Specific embodiment
For making the purpose of this utility model, technical scheme and advantage become more apparent, with reference to embodiment and accompanying drawing,
The utility model is described in further detail, and exemplary embodiment of the present utility model and its explanation are only used for explaining this
Utility model, is not intended as to restriction of the present utility model.
Embodiment
As shown in Figure 1, 2, the good valve element of a kind of wearability, including sphere body 1, described sphere body 1 includes valve casing 2 He
Channel cylinder 3, described valve casing 2 is hollow ball, and its welded top has the valve rod union joint 4 of cylinder, and described valve rod union joint 4 pushes up
Portion is provided with valve rod connecting hole 41.Valve casing 2 left and right sides is respectively provided with the diameter circular hole 21 equal with channel cylinder 3 internal diameter, runner
Cylinder 3 is arranged in valve casing 2 and its two ends is connected with valve casing 2 about circular hole 21 respectively, described valve casing 2 inwall and channel cylinder 3 outer wall
Between be fixed with several ribs 5, on described valve casing 2 outer wall and channel cylinder 3 inwall have 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.
Described valve casing 2 and channel cylinder 3 pass through to be weldingly connected.
During use, this utility model valve element is installed in ball valve, using valve rod union joint 4, valve rod one end is fixed on valve
In lever attachment hole 41, because one layer of overcoat 6 is adhered in valve casing 2 and channel cylinder 3 periphery, therefore this utility model valve element is used
When the transmission of the fluid media (medium) with granule, valve element is it can be avoided that by erosion medium resistance.Greatly prolong ball valve to pass in the medium with granule
Service life in defeated, reduces fluid transmission cost.
Above-described specific embodiment, is entered to the purpose of this utility model, technical scheme and beneficial effect
One step describes in detail, be should be understood that and the foregoing is only specific embodiment of the present utility model, is not used to limit
Fixed protection domain of the present utility model, all any modifications within spirit of the present utility model and principle, made, equivalent replaces
Change, improve, should be included within protection domain of the present utility model.
