Abstract
The utility model discloses a fixed ball valve of cast steel flange worm -drive, its characterized in that: cast steel deputy valve body and the cast steel main valve body constitutes the major structure of this ball valve, and the cast stainless steel ball is located the inside that has the major structure that cast steel deputy valve body and cast steel main valve physically constitute, and the cast stainless steel ball should set up with nonrust steel valve pole pair, setting up butadiene acrylonitrile rubber O shape circle and polytetrafluoroethylene valve lever bushing on the nonrust steel valve pole, setting up the carbon steel connecting plate on the cast steel main valve body, carbon steel connecting plate upper portion sets up carbon steel valve pole adapter sleeve. The utility model discloses the valve rod adopts prevents pop -up structure, and the elastic construction with polytetrafluoroethylene gasket double sealing is enclosed to stem seal adoption rubber O shape, the valve seat seal face compresses tightly makes every effort to overcome the your beautiful writings crack adjustment through the sino -French, there is the supporting at the upper and lower both ends of spheroid, and flexibility, light is opened and close to rigidity, and practical life is long, adopt manual worm wheel operation ware, reduced the arm of force, reduced moment, be applicable to the outdoor underground piping installation that the operating space is little.
Description
Technical field
The utility model relates to a kind of ball valve, especially a kind of cast steel flange worm drive Fixed ball valve.
Background technique
Fuel gas ball valve makes open-shut device with the spheroid with circular channel, and spheroid rotates the valve realizing switching motion with valve rod.The open-shut device of fuel gas ball valve is a porose spheroid, rotates around the axis perpendicular to passage, thus reaches the object opening and closing passage.Fuel gas ball valve is mainly for opening and closing pipeline and equipment medium.Fuel gas ball valve can be divided into by structural type: floating ball valve, fixing ball valve, elastic ball valve and oil sealing ball valve; Can be divided into straight energy formula, angie type and Three way type etc. by passage, Three way type can be divided into again T-shaped and L shape two kinds.Thread type connection, Flange joint and welding type three kinds can be divided into by connecting part's work.But when existing ball valve is installed, the position leaving valve handle rotation can not be used as throttling; The ball valve of tape handler should uprightly be installed; But the outdoor under ground piping that existing ball valve is not suitable for operating space little is installed.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cast steel flange worm drive Fixed ball valve at this; This ball valve is applicable to the media such as rock gas, artificial coal gas, liquefied petroleum gas (LPG), oil, water; Adopt manual worm gear operator, reduce the arm of force, reduce moment, the outdoor under ground piping being applicable to operating space little is installed.
The utility model realizes like this, construct a kind of cast steel flange worm drive Fixed ball valve, it is characterized in that: described cast steel flange worm drive Fixed ball valve comprises cast steel auxiliary valve body, polytetrafluoroethylene sealing gasket, Cast Stainless Steel ball, cast steel main valve body, stainless steel valve rod, nitrile butadiene rubber O shape circle, teflon valve lever bushing, carbon steel connecting plate, carbon steel valve rod connecting sleeve, worm and gear drive unit; Cast steel auxiliary valve body and cast steel main valve body form the agent structure of this ball valve, and described Cast Stainless Steel ball is positioned at the inside of the agent structure having cast steel auxiliary valve body and cast steel main valve body to form; And described Cast Stainless Steel ball and Stainless Steel Valve pole pair should be arranged; Stainless steel valve rod is arranged nitrile butadiene rubber O shape circle and teflon valve lever bushing, cast steel main valve body is arranged carbon steel connecting plate, carbon steel connecting plate top arranges carbon steel valve rod connecting sleeve, and carbon steel valve rod connecting sleeve corresponds to the upper end portion of stainless steel valve rod.
The utility model has the advantage of: the utility model provides a kind of cast steel flange worm drive Fixed ball valve by improving at this; Valve rod adopts anti-ejecting structure, and valve stem seal adopts the elastic structure of rubber o-ring and teflon gasket double seal; Sealing surface of seat is compressed to make every effort to overcome and is adjusted by middle flange gap; There is supporting at the upper and lower two ends of spheroid, and position is fixed, and open and close flexible, light, physical life is long; Adopt manual worm gear operator, reduce the arm of force, reduce moment, the outdoor under ground piping being applicable to operating space little is installed.
Accompanying drawing explanation
Fig. 1 is the structural representation of cast steel flange worm drive Fixed ball valve described in the utility model.
