Description
Technical field
The present invention relates to technical field of valve manufacturing, specifically, being a kind of bonnet structure of super large caliber welding ball valve.
Background technology
Valve is for being opened and closed pipeline, control flow direction, the parameter for adjusting and controlling 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
Component has the function of cut-off, adjusting, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting or overflow pressure relief etc..
Valve can be used for controlling empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radioactivity
The flowing of the various types fluid such as medium.Valve is also divided into cast iron valve, cast steel valve, stainless valve according to material（201、
304,316 etc.）, chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized valve etc..
Regulating valve also known as control valve, in industrial automation process control field, by receiving regulation unit output
Control signal, by power operation go to change rate-of flow, pressure, temperature, the technological parameters such as liquid level final control element.
Generally it is made of executing agency and valve.If pressing stroke feature, regulating valve can be divided into Direct Travel and angle stroke；Match by it and holds
The power that row mechanism uses can be divided into pneumatic control valve, electric control valve, three kinds of hydraulic adjusting valve；By its function and characteristic
It is divided into three kinds of linear characteristic, equal percentage characteristics and parabolic characteristic.Regulating valve is suitable for empty gas and water, steam, various corrosivity
The media such as medium, mud, oil product.English name：Control valve, position number usually FV beginnings.Regulating valve common classification：Pneumatically
Regulating valve, electric control valve, hydraulic adjusting valve, direct-operated regulator, but existing regulating valve is there is significant limitation,
It cannot be satisfied the needs of modernization industry production.
Current major city heat supply engineering long-distance transport pipes super large caliber all-welded ball valve demand increasingly increases, due to state
The limitation of interior technology and manufacture level, required valve are at based on import, increase project cost.
Invention content
It is an object of the invention to provide a kind of bonnet structures of super large caliber welding ball valve, can be used in super large caliber and weld
On access valve, meet different industrial production needs.
In order to achieve the above object, the present invention is as follows using technical solution：
A kind of bonnet structure of super large caliber welding ball valve, including crown portion and cap bar part, crown portion and cap bar part
It is made of integral molding techniques, crown portion section is regular hexagon, and there are one cylinder shape groove is downward for crown portion centre
It extends in and forms an inner cavity inside cap bar part, the top and bottom of crown portion use fillet design, the angle [alpha] of fillet
It is 15 °.
Further improvement of the present invention is provided with a circle rectangular preiection on the outside of cap bar part.
Further improvement of the present invention, the upper end of crown portion is to the height h1's of its lower end and height h2 of entire bonnet
Ratio is 1:3, the height h4 and the ratio of protrusion lower end to the height h3 of cap bar bottom of raised upper end to cap bar part bottom are
3:1。
Further improvement of the present invention, the ratio of the outer diameter h5 of crown portion regular hexagonal section and the height h2 of entire bonnet
Example is 2：1.
Beneficial effects of the present invention：The present invention acts on super large caliber ball valve, simple in structure, rationally distributed, has one
Fixed versatility and leakproofness.

Fig. 2 is the crown portion cross-sectional structure schematic diagram of the present invention.
In figure, 1- crown portions, 2- cap bar parts, 3- protrusions, the inner cavities 4-, 5- grooves.
Specific implementation mode
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and is further retouched in detail
It states, the embodiment is only for explaining the present invention, does not constitute and limits to protection scope of the present invention.
Embodiment：As depicted in figs. 1 and 2, a kind of bonnet structure of super large caliber welding ball valve, including 1 He of crown portion
Cap bar part 2, crown portion 1 are made with cap bar part 2 of integral molding techniques, and 1 section of crown portion is regular hexagon, cap
There are one cylinder shape grooves 5 to extend downwardly one inner cavity 4 of formation inside cap bar part 2 among top part 1, cap bar part 2
Outside is provided with a circle rectangular preiection 3, and the top and bottom of crown portion 1 use fillet design, and the angle [alpha] of fillet is 15 °.
In the present embodiment, ratio of the upper end of crown portion 1 to the height h1 of its lower end and the height h2 of entire bonnet
It is 1:The ratio of 3, the height h4 of raised 3 upper ends to 2 bottom of cap bar part and raised 3 lower ends to the height h3 of cap bar bottom is 3:
The ratio of 1, the outer diameter h5 of 1 regular hexagonal section of crown portion and the height h2 of entire bonnet are 2：1.
The particular use of the present embodiment：The present embodiment acts on the top of regulating valve, the top of valve body is embedded in, to valve body
Inside plays the role of dust-proof isolation, and the setting of the protrusion of cap bar part surrounding makes the connection between bonnet and valve body more
Fitting is close, has good leakproofness.
The basic principles and main features and advantage of the present invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe the originals of the present invention
