Description
Technical field
The utility model belongs to valve body manufacture field, is related to a kind of butterfly valve plate processing, especially a kind of assembly type spot welding
Butterfly valve component.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve simple in structure, and the switch available for low pressure pipeline medium controls, and leads to
Cross the deflection angle for changing butterfly valve plate, you can the flow of medium is controlled, available for the empty gas and water of control, steam, various corrosivity
The flowing of all kinds fluid such as medium, mud, oil product, liquid metal and radiating medium, producer, coal gas, natural gas,
Liquefied petroleum gas, town gas, hot and cold air, chemical industry smelt and the engineering system such as generation environment-friendly, building water supply and drainage in have extensively
Application.
Butterfly valve plate of the prior art is integrally cast typically by casting technique, and there are shortcomings, such as cast
Making technique needs a large amount of consumption coals, and cost high pollution is big, the environmental issue paid attention to increasingly especially for country, and casting technique will produce
Raw substantial amounts of sulphur, sulphur emissions cause environment into air seriously to pollute.
In addition, butterfly valve is in use, and for the material of some properties, the material meeting under the influence of temperature in use
Generation expansion is uneven, and the phenomenon stuck with positioning sleeve or connector easily occurs in valve rod, increases the frictional force of transmission shaft, forces biography
Moving axis easily twists off, and causes valve cisco unity malfunction so that equipment parking causes great loss.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, there is provided it is a kind of without casting technique, it is anti-tired
Labor intensity height, good corrosion resistance, of low cost, energy-saving and environment-friendly assembly type spot welding butterfly valve plate.
The utility model solves above-mentioned technical problem and takes following technical scheme to realize：
A kind of assembly type spot welding butterfly valve component, including upper valve plate, lower valve plate and axostylus axostyle, it is homogeneous on upper valve plate and lower valve plate
System goes out to have two symmetrical semi arch chambers, and the semi arch intracavitary of valve plate is welded with axle sleeve on described, and the axle sleeve includes
First axle sleeve and the second axle sleeve, coaxially offer through hole in the first axle sleeve, blind hole, the axostylus axostyle are coaxially offered in the second axle sleeve
It is coaxial to be mounted in by the first axle sleeve detachable interposing in the blind hole of the second axle sleeve, upper valve plate and lower valve plate surrounding spot welding docking
Form valve body.
Moreover, the inner surface of valve plate and lower valve plate is welded with reinforcing plate on described.
The advantages of the utility model and have the beneficial effect that：
1st, the upper valve plate and lower valve plate of this butterfly valve component are formed by compacting, and the first axle sleeve and the second axle sleeve are welded on
The corresponding semi arch intracavitary of valve plate, recycles the mode of spot welding that upper valve plate and lower valve plate surrounding are corresponded to welding and forms complete valve
Body, axostylus axostyle is coaxially by the first axle sleeve detachable interposing in the blind hole of the second axle sleeve, without traditional integrally casting, energy-saving ring
Protect.
2nd, this butterfly valve component is welded with the first axle sleeve and the second axle sleeve in the semi arch intracavitary of upper valve plate, effectively solves butterfly valve
The easily stuck technical problem of axostylus axostyle, axostylus axostyle detachably insert valve plate in use, easy maintenance and replacement, and effectively reducing makes
Use cost.
3rd, design is scientific and reasonable, simple in structure for the utility model, strategic structural tradition integrally casting technique, without casting,
Pollution is not produced, energy consumption is low, and effectively improves the positioning accuracy of butterfly valve plate, it is ensured that the steady operation of butterfly valve valve, reduces zero
Friction between part, prolongs the service life, and effectively reduces cost, economic and environment-friendly, suitable for wideling popularize application.

Embodiment
Below by specific embodiment, the utility model is described in further detail, following embodiments be it is descriptive, no
It is limited, it is impossible to which the scope of protection of the utility model is limited with this.
A kind of assembly type spot welding butterfly valve component, such as Fig. 1, including upper valve plate 1, lower valve plate 5 and axostylus axostyle 4, in upper valve plate with
Homogeneous system goes out to have two symmetrical semi arch chambers 2 on valve plate, and such as Fig. 2, the semi arch intracavitary of valve plate is welded with axis on described
Set, such as Fig. 3, Fig. 4, the axle sleeve includes the first axle sleeve 3 and the second axle sleeve 7, coaxially offers through hole in the first axle sleeve, and second
Blind hole is coaxially offered in axle sleeve, the axostylus axostyle is coaxially by the first axle sleeve detachable interposing in the blind hole of the second axle sleeve, institute
Upper valve plate and lower valve plate the surrounding spot welding stated docks to form valve body, and the inner surface of valve plate and lower valve plate is welded with reinforcement on described
Plate 6.
The manufacture method of the utility model：
Upper valve plate and lower valve plate are suppressed respectively using the mould with semi arch model, and the first axle sleeve and the second axle sleeve are welded
The corresponding semi arch intracavitary of valve plate is connected on, recycles the mode of spot welding that upper valve plate and lower valve plate surrounding are corresponded to welding and has been formed
Whole valve body, axostylus axostyle is coaxially by the first axle sleeve detachable interposing in the blind hole of the second axle sleeve, without traditional integrally casting, section
Can be environmentally friendly, and dismounting axostylus axostyle can be replaced in use, effectively solving butterfly valve body, axostylus axostyle is easily stuck in use
Technical problem.
