Valve is for being opened and closed pipeline, control flow direction, regulation and the parameter of control pumped (conveying) medium（Temperature, pressure and flow）
Pipeline fittings.According to its function, shut-off valve, check-valves, regulating valve etc. can be divided into.Valve is the control in fluid delivery system
Part, there is cut-off, regulation, water conservancy diversion, prevent the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.
Valve can be used for controlling empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radioactivity
The flowing of all kinds fluid such as medium.Valve is also divided into cast iron valve, cast steel valve, stainless valve according to material（201、
304th, 316 etc.）, chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized valve etc..
All-welded ball valve is because valve seat is made up of carbonization teflon seal ring and disk spring, so to pressure and temperature
The change of degree is adaptable, will not be produced in the range of mark pressure and temperature and any let out cunning.Typically using carbon steel without
Stitch the compressing Integral welded ball valve of steel pipe, there is good sealing property and decay resistance, be widely used in natural gas,
Oil, heat supply, chemical industry and the isometric defeated pipeline field of thermoelectricity pipe network., can not but existing ball valve is there is significant limitation
Meet the needs of modernization industry production.
The content of the invention
The purpose of the present invention is exactly by transforming invention handle, making it have S-shaped shape, be easy to manual grasping, more
Convenient and swift folding is added to invent, meanwhile, make ball valve that there is good sealing property using multiple sealing rings.
In order to achieve the above object, the present invention is as follows using technical scheme：
A kind of all-welded ball valve of S types handle, including valve body and extension tube, the both sides of valve body are each provided with an extension tube, valve
Body is internally provided with a ball, and extension tube stretches to its inside from the both sides of valve body respectively and is connected with sphere, and ball top is prolonged upwards
Stretch and be provided with a cylindrical axis and exceed body portion, be provided with cover type nut at the top of axis, cover type nut is adopted with axis
With threaded connection, cover type nut and the joint portion at the top of axis are provided with the handle to stretch out, and handle use S types, handle and
The link position of axis is provided with alignment pin and plays further positioning fixation.
In the present invention, by the transformation to handle, S-shaped shape is become, easily facilitates manual grasping, makes it more square
Just quickly folding.
Further improvement of the present invention, the outer peripheral face of axis are provided with a circle bottom bracket axle, the connecting portion setting of axis and ball
There is axis plain cushion, the setting of bottom bracket axle causes whole ball valve to make in transport using a protection is served among process to axis
With the setting of axis plain cushion causes the junction better tightness of axis and ball.
Further improvement of the present invention, butterfly spring, ball pad seat and ball pad, butterfly are provided with this between extension tube and ball
The setting of spring causes the connection between extension tube and ball to have cushion space, avoids hard collision so as to cause whole ball valve
The setting of damage, ball pad seat and ball pad causes the junction better tightness between extension tube and ball.
Further improvement of the present invention, during the connecting portion between the top of axis and bottom bracket axle is disposed with from top to bottom
Shaft retaining ring, axis O-ring and axle sleeve.
Further improvement of the present invention, a floor clip, the thrust washer are provided between axis and cover type nut
It is arranged on the top of handle.
Further improvement of the present invention, the tail end outer cover of handle are set as grip rubber equipped with a rubber sleeve, are easy to
It is artificial to grasp, more meet human engineering mechanics.
Further improvement of the present invention, valve body use phosphorus content to be made up of 0.2% No. 20 Steel materials, and axis uses
20Cr13 materials are made.
Beneficial effects of the present invention：Compared with existing ball valve, S-shaped shape is used at handle of the invention, easily facilitates people
Work grasps so that folding valve is more time saving and energy saving, convenient and swift.
