Abstract
The present invention relates to technical field of valve manufacturing, specifically, it is a kind of bonnet structure of Novel regulating valve, including crown portion and cap bar part, crown portion is made with cap bar part of integral molding techniques, crown portion section is regular hexagon, there is a cylinder shape groove to extend downwardly among crown portion and be internally formed an inner chamber in cap bar part, the present invention is simple in construction, it is rationally distributed, with certain versatility, it is embedded in the top of valve body, the effect of dust-proof isolation is served to valve inner, the raised setting of cap bar part surrounding causes the connection between bonnet and valve body to be more bonded closely, with good sealing.
Description
Technical field
The present invention relates to technical field of valve manufacturing, is a kind of bonnet structure of Novel regulating valve specifically.
Background technology
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..
Regulating valve also known as control valve, in industrial automation process control field, exported by receiving regulation unit
Control signal, go to change the final control element of rate-of flow, pressure, temperature, the technological parameter such as liquid level by power operation.
Typically it is made up of executing agency and valve.If pressing stroke feature, regulating valve can be divided into Direct Travel and angle stroke；Match somebody with somebody by it and hold
The power that row mechanism uses, pneumatic control valve, electric control valve, three kinds of hydraulic adjusting valve can be divided into；By its function and characteristic
It is divided into three kinds of linear characteristic, equal percentage characteristics and parabolic characteristic.Regulating valve is applied to empty gas and water, steam, various corrosivity
The media such as medium, mud, oil product.English name：Control valve, position number generally 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,
The needs of modernization industry production can not be met.
The content of the invention
It is an object of the invention to provide a kind of bonnet structure of Novel regulating valve, can be expired with new regulating valve
The different industrial production of foot needs.
In order to achieve the above object, the present invention is as follows using technical scheme：
A kind of bonnet structure of Novel regulating valve, including crown portion and cap bar part, crown portion use one with cap bar part
Body formed technology is made, and crown portion section is regular hexagon, has a cylinder shape groove to extend downwardly among crown portion
Cap bar part is internally formed an inner chamber.
Further improvement of the present invention, a circle rectangular preiection is provided with the outside of cap bar part.
Further improvement of the present invention, the top and bottom of crown portion use fillet design, and the angle [alpha] of fillet is
15°。
Further improvement of the present invention, the height h1 of the upper end of crown portion to its lower end is with the height h2's of whole bonnet
Ratio is 1:3, the height h4 of raised upper end to cap bar part bottom and raised lower end are to the height h3 of cap bar bottom ratio
3:1。
Further improvement of the present invention, the external diameter h5 of the crown portion regular hexagonal section and height h2 of whole bonnet ratio
Example is 2：1.
Beneficial effects of the present invention：The present invention is acted in regulating valve, simple in construction, rationally distributed, has certain lead to
With property and sealing.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
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- is raised, 4- inner chambers, 5- grooves.
Embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and further retouched in detail
State, the embodiment is only used for explaining the present invention, and protection scope of the present invention is not formed and limited.
Embodiment：As depicted in figs. 1 and 2, the bonnet structure of a kind of Novel regulating valve, including crown portion 1 and cap bar portion
Points 2, crown portion 1 is made with the use integral molding techniques of cap bar part 2, and the section of crown portion 1 is regular hexagon, crown portion
There is a cylinder shape groove 5 to extend downwardly among 1 and be internally formed an inner chamber 4 in cap bar part 2, the outside of cap bar part 2 is set
A circle rectangular preiection 3 is equipped with, the top and bottom of crown portion 1 use fillet design, and the angle [alpha] of fillet is 15 °.
In the present embodiment, the upper end of crown portion 1 to its lower end height h1 and whole bonnet height h2 ratio
For 1:The ratio of 3, the height h4 of raised 3 upper ends to the bottom of cap bar part 2 and raised 3 lower ends to the height h3 of cap bar bottom is 3:
1, the external diameter h5 of the regular hexagonal section of crown portion 1 and the height h2 of whole bonnet ratio 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 serves the effect of dust-proof isolation, and the raised setting of cap bar part surrounding causes connection between bonnet and valve body more
Fitting is close, has good sealing.
General principle, the main features and advantages 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, the original for simply illustrating the present invention described in above-described embodiment and specification
Reason, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
