Abstract
This utility model relates to the Novel sphere structure of a kind of Coal Chemical Industry ball valve, including valve body, spheroid, anti-gray structure, valve rod, lower shaft, support, hardened layer, described valve body is installed on Coal Chemical Industry pipeline, spheroid is set inside it, described spheroid is opening and closing element, it is with lower shaft as pivot point, is implemented the function opened and closed by valve rod fixed thereon, and on valve rod, fixed support controls direction of rotation；Described spheroid is provided with optimization sealing surface, and its outer surface arranges one layer of hardened layer.The beneficial effects of the utility model are: this device is on the premise of ensureing to meet closure size, spheroid useless sealing surface part is fallen in turning, not only meet seal request but also reduce seal friction area, adding of hardened layer reduces ball seal surface wear, the risk of corrosion, improve the service life of Coal Chemical Industry ball valve and the work efficiency of machinery entirety, reduce maintenance and maintenance cost.
Description
Technical field
This utility model relates to a kind of Coal Chemical Industry ball-valve structure, particularly relates to a kind of Coal Chemical Industry ball valve being provided with Novel sphere structure and being easy to fast opening and closing.
Background technology
Ball valve is that one is driven by valve rod, and the valve rotated around ball valve axis, also can be used for regulation and the control of fluid, at oil, petrochemical industry, chemical industry, power plant, the fields such as metallurgy, especially coal chemical technology is widely used, ball valve becomes its important device, Coal Chemical Industry ball valve is all to use metal hard-sealing ball valve at present, the sealing surface of its spheroid is to be served as by whole sphere, sealing area is whole area of spherical surface, valve seat and spheroid are at cinder in actual use, dust, high temperature, under the environment such as high pressure, easily wear and tear, scratch, wash away, the phenomenons such as corrosion, cause the damage in ball seal face, valve leak, significantly lose the service life of valve.Further, after ball valve itself is damaged, damage can not be immediately appreciated that, cause more serious consequence unavoidably, generally require the increase cost of overhaul to use and processing cost, the part short operational paradigm that can reduce again machinery entirety greatly in service life, cause unnecessary loss.
The Novel sphere structure of a kind of Coal Chemical Industry ball valve described in this utility model patent, it changes the sealing surface of ball valve, reduces friction area, and by Surface hardening treatment, increase service life and the performance of Coal Chemical Industry ball valve, reduce and use and maintenance cost.
Therefore, for the above, need prior art is effectively innovated.
Utility model content
For disadvantages described above, this utility model provides the Novel sphere structure of a kind of Coal Chemical Industry ball valve, to solve many deficiencies of prior art.
For achieving the above object, this utility model is by the following technical solutions:
A kind of Novel sphere structure of Coal Chemical Industry ball valve, including valve body, spheroid, anti-gray structure, valve rod, lower shaft, support, hardened layer, optimization sealing surface, described valve body is installed on Coal Chemical Industry pipeline, and be bolted, spheroid is set inside it, described spheroid is opening and closing element, for cutting off, distribute and change the flow direction of medium, it is with lower shaft as pivot point, is implemented the function opened and closed by valve rod fixed thereon, and on valve rod, fixed support controls direction of rotation；
Described spheroid is irregular sphere; it is divided into upper, middle and lower three part; top and lower external face are the sphere of complete radian, middle part through turning without sealing surface, formed and optimize sealing surface; for reducing seal friction area; spheroid middle height is identical with Coal Chemical Industry pipe diameter, and outer surface of spheroid arranges one layer of hardened layer, and described hardened layer is that hard alloy is formed through operations such as processing grindings; for protecting spherome surface, anticorrosion, anti-wear.
The Novel sphere structure of a kind of Coal Chemical Industry ball valve described in the utility model have the beneficial effect that this device ensure meet closure size on the premise of, spheroid useless sealing surface part is fallen in turning, not only meet seal request but also reduce seal friction area, adding of hardened layer reduces ball seal surface wear, the risk of corrosion, improve the service life of Coal Chemical Industry ball valve and the work efficiency of machinery entirety, reduce maintenance and maintenance cost.

Detailed description of the invention
As shown in Figure 1-2, the Novel sphere structure of a kind of Coal Chemical Industry ball valve described in this utility model embodiment, including valve body 1, spheroid 2, anti-gray structure 3, valve rod 5, lower shaft 6, support 8, hardened layer 9, optimize sealing surface 10, described valve body 1 is installed on Coal Chemical Industry pipeline 7, and be bolted, spheroid 2 is set inside it, described spheroid 2 is opening and closing element, for cutting off, distribute and change the flow direction of medium, it is with lower shaft 6 as pivot point, implemented the function opened and closed by valve rod 5 fixed thereon, on valve rod 5, fixed support 8 controls direction of rotation；
Described spheroid 2 is irregular sphere; it is divided into upper, middle and lower three part; top and lower external face are the sphere of complete radian, middle part through turning without sealing surface, formed and optimize sealing surface 10; for reducing seal friction area; spheroid 2 middle height is identical with Coal Chemical Industry pipeline 7 diameter, and spheroid 2 outer surface arranges one layer of hardened layer 9, and described hardened layer 9 is formed through operations such as processing grindings for hard alloy; for protecting spherome surface, anticorrosion, anti-wear.
The above-mentioned description to embodiment be for the ease of those skilled in the art it will be appreciated that and application this case technology, these examples obviously can be made various amendment by person skilled in the art easily, and General Principle described herein is applied in other embodiments without through performing creative labour.Therefore, this case is not limited to above example, and those skilled in the art should be in the protection domain of this case according to the announcement of this case, the improvement made for this case and amendment.
