Abstract
The present invention relates to a kind of companion flange protection device and guard method.Companion flange is in packaging, transport at present, because flange shape is irregular, generally taken in vanning and place sealing surface method directed downwardly, but because being spaced the rubber blanket or the easy play of plank of flange, the risk in lifting, damage of being collided between flange flange adjacent thereto in transportation can not be avoided completely；Simultaneously in order to protect flange end groove, surface etc., each wooden case can only put one layer of flange, if, it is necessary to be filled with multiple wooden cases, waste packaging material when companion flange is more needed for equipment.The inventive method includes：Ring flat-plate（1）, pad is provided between described ring flat-plate and companion flange（2）, cylinder is provided with described ring flat-plate（3）, described cylinder top is provided with cover plate（4）, described ring flat-plate and described cylinder, described cylinder are connected with described cover plate by welding manner.The present invention is applied to the safe fixing and packaging of companion flange.
Description
Technical field：
The present invention relates to a kind of companion flange protection device and guard method.
Background technology：
In recent years, with the going from strength to strength of China's chemical industry, develop, the use of pressure vessels for the chemical industry is more and more, and it is pressed
The design parameters such as power, temperature also more and more higher, so pressure vessels for the chemical industry flange much all uses non-standard de-sign, flange is in design, material
Material performance, manufacture etc. have higher requirement, and direct selection standard flange far can not meet product requirement.It is so more next
More owner's selections provide companion flange and corresponding bolt, nut, pad by vessel fabrication producer by vessel flange requirement,
Rather than flange manufactory is voluntarily looked for purchase by standard.Companion flange specification, pressure rating, shape due to each equipment etc. are general
All compare more, it is ensured that flange safe, economic transport design a kind of safe and reliable, simple and practical matched pair technique to scene
Blue protection device is just particularly important.
The companion flange that general device provides can use in packaging, transport and load wooden-box package transport or installed in setting
The mode transported together on standby flange.In device pairing flange transportation, it is most important that prevent flange sealing surface, end slope
Mouthful and outer surface collided with damage in lifting, transport.
Because flange shape is irregular, is typically taken in vanning and place sealing surface method directed downwardly, on the one hand can be with
Prevent sealing surface from being collided with other parts, allow end groove not contacted upward with other objects；Can also as far as possible reduce lifting,
Flange rocks in transportation.But also there is the shortcomings that inevitable in this method：One, because being spaced the rubber blanket or wood of flange
The easy play of plate, the risk in lifting, damage of being collided between flange flange adjacent thereto in transportation can not be avoided completely；
Two, in order to protect flange end groove, surface etc., each wooden case can only put one layer of flange, if companion flange needed for equipment compared with
, it is necessary to be filled with multiple wooden cases when more, packaging material is wasted.
The content of the invention：
It is an object of the invention to provide a kind of companion flange protection device and guard method.
Above-mentioned purpose is realized by following technical scheme：
A kind of companion flange protection device, its composition include：Ring flat-plate, pad, cylinder, cover plate, described ring flat-plate and pairing
Pad is provided between flange, cylinder is provided with described ring flat-plate, described cylinder top is provided with cover plate, described ring flat-plate
With described cylinder, described cylinder is connected with described cover plate by welding manner.
Described companion flange protection device, is provided with one group of bolt hole on described ring flat-plate, described bolt hole according to
The screw quantity of described companion flange is uniform on described ring flat-plate, and ensures that the internal diameter of described ring flat-plate is more than described match somebody with somebody
To the big neck external diameter of flange oblique cone,；Described gasket material uses XB450, rubber blanket or sealing protection pad, and according to matched pair technique
Blue screw quantity uniformly opens screw on pad, and described pad size is pressed described ring flat-plate size, padded in described matched pair technique
Blue ring flange lower surface；The height of described cylinder should ensure lid described after installing by described companion flange size design
Plate has spacing with described companion flange end groove, does not touch；Described ring flat-plate, described cylinder, described cover plate
Material uses carbon steel.
The guard method of described companion flange protection device, in use, lining will be put between companion flange and vessel flange
Pad protection flange sealing surface, pad is placed on and protects companion flange outer surface in companion flange ring flange lower surface, by ring flat-plate, lid
Plate, the protection device of cylinder welding are fixed together by bolt, nut and companion flange and vessel flange, and pairing is effectively ensured
Flange will not collide with, and flange end groove does not contact with other objects, while can seal vessel flange mouth, prevent into
Enter debris, foreign matter.
Beneficial effects of the present invention：
1. the present invention protects flange sealing surface in use, pad will be put between companion flange and vessel flange, pad is put
Companion flange outer surface is being protected in companion flange ring flange lower surface, the protection device of ring flat-plate, cover plate, cylinder welding is being passed through
Bolt, nut and companion flange and vessel flange are fixed together, and companion flange, which is effectively ensured, to collide with, flange end
Groove does not contact with other objects, while can seal vessel flange mouth, prevents from entering debris, foreign matter.
The present invention is for fixing the bolt of companion flange, nut is carried using equipment, can also be according to actual feelings
Condition designed, designed, packaging special bolt, nut are provided, can be real well by the safe fixing and packaging of companion flange by the device
Show the protection to each key position of flange, while save the packaging materials such as wooden case, safe and reliable, economic, simple reality
With.
