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 anti-jamming assembling
The two-way spot welding butterfly valve component of formula.
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, the energy-saving and environment-friendly anti-jamming two-way spot welding butterfly valve component of assembly type.
The utility model solves above-mentioned technical problem and takes following technical scheme to realize：
A kind of two-way spot welding butterfly valve component of anti-jamming assembly type, including valve body, axostylus axostyle and detachable stop collar, the valve body
Including upper valve plate and lower valve plate, homogeneous system goes out to have two symmetrical semi arch chambers on upper valve plate and lower valve plate, on described
The semi arch intracavitary of valve plate is integrally molded sleeve, and the axostylus axostyle is coaxially installed in the sleeve, the upper valve plate and lower valve
Plate surrounding spot welding docks to form valve body, and the detachable stop collar is detachably arranged on the sleeve.
Moreover, the detachable stop collar is provided at both ends with screw nipple, internal thread groove is offered in the sleeve,
Detachable stop collar is connected through a screw thread pipe and is coaxially removably mounted in the internal thread groove of sleeve, is coaxially offered in sleeve
Through hole, is coaxially arranged with bearing holder (housing, cover) in detachable stop collar, and the axostylus axostyle coaxially installed through hole and bearing holder (housing, cover).
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, recycle the mode of spot welding by upper valve plate and under
Valve plate surrounding corresponds to welding and forms complete valve body, without traditional integrally casting, energy conservation and environmental protection.
2nd, this butterfly valve component upper valve plate semi arch intracavitary it is integrally molded have sleeve, detachable stop collar is detachably set
On the sleeve, effectively solving butterfly valve plate, the easily stuck technical problem of axostylus axostyle, axostylus axostyle detachably insert in use,
Easy maintenance and replacement, effectively reduces 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.
