Abstract
The utility model discloses an all-welded ball valve and relates to a valve. The all-welded ball valve comprises a connecting sleeve, a quartered ring, a plane bearing, a ball body, a fireproof ring, a valve seat, an end cover, a valve body and a cylindrical pin shaft, wherein the valve seat and the fireproof ring are arranged in a valve seat ring assembly; a spring and a base are arranged in the end cover to form an end cover assembly; the valve seat ring assembly is arranged in the end cover assembly; the end cover assembly is connected with the ball body via the cylindrical pin shaft; one end of the end cover is welded to the valve body; one side of the ball body is connected with the valve body via the cylindrical pin shaft; the ball body is connected with a valve rod; the quartered ring is arranged in the connecting sleeve; and the connecting sleeve is connected with the valve body. The ball valve is simple and reasonable in structure, small in size, beautiful in appearance and convenient to construct and is labour-saving and material-saving since only a small shallow shaft needs to be arranged on the ground. The ball valve is of an all-welded structure, and is made of a material which is same as the material of a pipeline, and therefore the pipeline is ageing-resistant and hardly deforms or bursts, thus improving the sealing performance of the ball valve.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of all-welded ball valve.
Background technique
Since China reform and opening-up, national economy obtains rapid growth, and " scientific and technical innovation, autonomous innovation " become the main flow of the present industrial development of China, and China's industry is progressively to intensive style, energy-saving and emission-reduction, the future development of low-carbon (LC).Ball valve is to utilize spheroid as the valve body of open-shut device, and during work, spheroid does around the valve body center line opening and closing that rotation reaches valve.How with bolts existing ball valve body is, and the valve body material is different from the material of institute connecting tube, easily produces unbalanced stress, causes the working life of pipeline burst, ball valve short, thereby causes medium to leak outside.When ball valve is installed under ground piping, need to build high large-scale valve well, increased operating expenses and engineering time, waste of manpower, material resources.In order to address these problems, R﹠D institution and science and technology in enterprise personnel utilize modern science and technology in constantly research, exploration, although obtained technically some progress, still exist the technical barrier that not yet overcomes in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of all-welded ball valve is provided, and is rational in infrastructure, and valve body adopts all-welded structure and the material identical with pipeline, and pipeline is not yielding, explosion, the phenomenon that medium leaks outside can not occur.When ball valve is installed under ground piping, only small-sized shallow well need be set on the ground, saved operating expenses and engineering time.
the technological scheme that its technical problem that solves the utility model adopts is: contain connecting sleeve, four minutes rings, plane bearing, spheroid, fire-protection ring, valve seat, end cap, valve body, cylindrical bearing pin, be provided with valve seat in the seat ring assembly parts, fire-protection ring, be provided with spring in end cap, base, formed the end cap assembly parts, the valve seat combination part is located in the end cap assembly parts, cylindrical bearing pin is connected the end cap assembly parts with spheroid, end cap one side is welded mutually with valve body, cylindrical bearing pin is connected a side of spheroid with valve body, spheroid is connected with valve rod, be provided with four minutes rings in connecting sleeve, connecting sleeve welds mutually with valve body, formed a kind of all-welded ball valve.
The know-why that its technical problem that solves the utility model adopts is: existing bolt is connected ball valve improve innovation, adopt all-welded mode, avoided medium to leak from connecting the gap at home and abroad.Because valve seat is made of carbonization teflon seal ring and spring, thus adaptable to the variation of pressure and temperature, can not produce any leakage in mark pressure and temperature scope.Valve body is selected the material identical with pipeline, the phenomenon of unbalanced stress can not occur, also can be due to earthquake and vehicle produce distortion during through ground, and pipeline is ageing-resistant.When this ball valve is installed on underground pipeline, need not build high large-scale valve well, only small-sized shallow well need be set on the ground, save operating expenses and engineering time.Can according to construction and the designing requirement of pipeline, adjust the length of valve body and the height of valve rod.The machining accuracy of spheroid is very accurate, operate light, without bad interference.
The utility model beneficial effect is: this ball-valve structure advantages of simple, and volume is little, and is aesthetic in appearance, and construction is convenient, only small-sized shallow well need be set on the ground, has saved the human and material resources resource.This ball valve adopts all-welded structure, selects the material identical with pipeline, makes pipeline ageing-resistant, and not yielding, explosion have improved the sealability of ball valve.
Description of drawings
The below further describes the utility model in conjunction with the accompanying drawings and embodiments:
It is a kind of structural representation of all-welded ball valve in figure.
In the drawings: 1. connecting sleeve, 2. four minutes rings, 3. plane bearing, 4. spheroid, 5. fire-protection ring, 6. valve seat, 7. end cap, 8. valve body, 9. cylindrical bearing pin.
Embodiment
In the drawings: be provided with valve seat 6, fire-protection ring 5 in the seat ring assembly parts, be provided with spring, base in end cap 7, formed the end cap assembly parts, the valve seat combination part is located in the end cap assembly parts, and cylindrical bearing pin 9 is connected the end cap assembly parts with spheroid 4, end cap 7 one sides are welded mutually with valve body 8, cylindrical bearing pin 9 is connected a side of spheroid 4 with valve body 8, spheroid 4 is connected with valve rod, is provided with four minutes rings 2 in connecting sleeve 1, connecting sleeve 1 welds mutually with valve body 8, has formed a kind of all-welded ball valve.
Existing bolt is connected ball valve improve innovation, adopt all-welded mode, avoided medium to leak from connecting the gap at home and abroad.Because valve seat 6 is made of carbonization teflon seal ring and spring, thus adaptable to the variation of pressure and temperature, can not produce any leakage in mark pressure and temperature scope.Valve body 8 is selected the material identical with pipeline, the phenomenon of unbalanced stress can not occur, also can be due to earthquake and vehicle produce distortion during through ground, and pipeline is ageing-resistant.When this ball valve is installed on underground pipeline, need not build high large-scale valve well, only small-sized shallow well need be set on the ground, save operating expenses and engineering time.Can according to construction and the designing requirement of pipeline, adjust the length of valve body 8 and the height of valve rod.The machining accuracy of spheroid 4 is very accurate, operate light, without bad interference.
