Description
Technical field
The utility model is related to a kind of flange of pipeline connection, more particularly to a kind of insulating flange.
Background technology
Insulating flange（Insulating flange）It is pair while having the sealing property and electricity of buried steel pipeline requirement
The general designation of the pipe flange joint of the electrical insulation capability required by change Corrosion and protection project.It includes a pair of steel flanges, two methods
The insulating sealer of your beautiful writings, flange fastener and fastener insulating part and a pair of the steel mutually welded respectively with two panels flange
Short tube.
It is the product of the industry productions such as oil, chemical industry that insulating flange and insulating joint are, its simple structure, using safety,
Dependable performance, obtains the extensive favorable comment of user.Insulating flange product has formed series, when there is special circumstances, can be wanted according to user
Otherwise designed is asked to manufacture.
Insulating flange is mainly used between the equipment such as gas transmission and distribution pipeline and gas pressure regulating, metering, storage, and it is mainly made
With being to isolate each intersegmental of gas transmission and distribution pipeline, equipment with mutually insulated between pipeline, chemical attack, extension tube are protected it from
Line and service life of equipment.
Authorization Notice No. is CN1719089, and the day for announcing is that the Chinese utility model patent on January 11 in 2006 discloses one
Plant and be applied to harbour, the insulating flange for connection of ship and shore pipelines in the ship-to-shore pipe line road of river port oil jetty, it is included being insulated by bolt and connected
The left flange plate and right ring flange for connecing, are lined with insulated enclosure pad, on a left side for the insulation between left flange plate and right ring flange
A resistance is at least overlapped between ring flange and right ring flange.Asia is inlaid between the flange of the left flange plate and right ring flange
Conductive filler ring and outer cladding oversheath.The insulating flange can make junction electrostatic reliable ground, can effectively separate again absolutely
The flowing of lot or luck by which people are brought together orchid both sides stray electrical current, with safe and reliable, the advantage of action effect stabilization.
But also there is following weak point in the utility model, the sealing between left and right ring flange and insulated enclosure pad is not
It is fine, long-term use is easily revealed, causes very big loss.
Utility model content
In order to sealing is poor between the left and right ring flange for overcoming above-mentioned insulating flange, the defect of leakage, this practicality are caused
It is new there is provided a kind of insulating flange, the better tightness of the insulating flange, long-term use does not result in leakage, service life yet
It is longer.
In order to solve the above technical problems, the technical scheme that the utility model is used is：
A kind of insulating flange, including two ring flanges and felt pad, felt pad are arranged between two ring flanges, its feature
It is：First annular groove and the second annular groove, the first ring are provided with the end face that described two ring flanges are in contact with felt pad
Sealing ring is filled with shape groove.
The rectangular cross-section of the first annular groove, the section of second annular groove is V-arrangement, rectangle or U-shaped.
Silica gel is filled with second annular groove.
The first annular groove, the second annular groove and ring flange are concentric.
Diameter of the diameter of the first annular groove less than the second annular groove.
The first annular groove and ring flange are arranged concentrically, the second annular groove and ring flange eccentric setting.
Compared with prior art, the utility model has the advantages that：
The utility model has the advantages that：
1st, the utility model includes two ring flanges and felt pad, and felt pad is arranged between two ring flanges, described two
First annular groove and the second annular groove are provided with the end face that individual ring flange is in contact with felt pad, are filled with first annular groove
Sealing ring.The utility model on the end face that two ring flanges are in contact with felt pad by being provided with first annular groove and second
Annular groove, is filled with sealing ring in first annular groove, and the sealing ring in first annular groove plays a sealing function, and the second ring
Shape groove cause two contacts of the ring flange with felt pad no longer be entirely face contact, such structure design, ring flange with insulation
Contact between pad is just even closer, will not reveal, better tightness, and long-term use will not also be revealed, and service life is longer.
2nd, the rectangular cross-section of the first annular groove of the utility model, the section of second annular groove is V-arrangement, rectangle or
U-shaped.When the section of the second annular groove is V-arrangement, two contacts of the ring flange with felt pad are no longer face contacts but linear contact lay, line
Contact is not in the uneven of face contact for face contacts, and contacts even closer, sealing property more preferably, with the
Sealing ring collective effect in one annular groove, serves good sealing function.
3rd, silica gel is filled with the annular groove of the utility model second.The filling gel in the second annular groove, can not only take
Obtain better seal effect, and the elastic reaction for passing through silica gel so that contact of the ring flange with felt pad is very tight, root
Originally be not in the phenomenon of leakage, trusted using safety.
4th, the first annular groove of the utility model, the second annular groove and ring flange are concentric.First annular groove, the second annular groove and
Ring flange is processed with one heart, it is easy to processed, while can also obtain better seal effect.
5th, diameter of the diameter of the first annular groove of the utility model less than the second annular groove.Such structure is, it is necessary to seal
Medium first pass through the effect of sealing ring and sealed, then by the silica gel sealing in the second annular groove, two seals, sealing effect
Fruit is more preferable, and smaller to the corrosion of silica gel, and service life is longer.
