Description
Technical field
The present invention relates to flange field, specifically a kind of fastening type flange connector.
Background technology
Flange (Flange), again call orchid flange or bead.Flange is interconnective part between pipe and pipe, for the connection between pipe end；Also there is the flange that the equipment that is used in is imported and exported, for the connection between two equipment, such as reductor flange.Flange joint or bump joint, refer to and be connected with each other the releasable connection as one group of combined sealing structure by flange, pad and bolt three.Pipe flange means the flange of pipe arrangement in plumbing installation, is used on equipment to mean the import and export flange of equipment.Perforation on flange, bolt makes two flanges be close to.Seal with liner between flange.Flange divides threaded (screwed connection) flange, welded flange and clip flange.Flange is all use in pairs, and low pressure pipeline can use wire connection flange, the use welded flange of four kilograms of pressure above.Plus sealing gasket between two panels ring flange, then fasten with bolt.The flange thickness of different pressures is different, and the bolt that they use is also different.Water pump and valve, when connecting with pipeline, the local of these equipment facilities, also make corresponding flange shape, also referred to as Flange joint.Every union piece making at two planar perimeter to be connected with simultaneously closing, is generally referred to as " flange ".
In the producing continuously of modern industry flange by dielectric corrosion, wash away, temperature, pressure, the factor such as vibrations impact, error due to sealing surface processing dimension, aging and the installation of potted component fastens the reasons such as improper, can inevitably cause the seepage of flange.If flange leakage problems can not be administered in time, under the washing away of medium, meeting makes seepage expand rapidly, causes the loss of material, the destruction of production environment, causes that enterprise shuts down and stops production, causes huge economic loss.If poisonous and harmful, inflammable and explosive dielectric leakage, it is also possible to cause the major accidents such as poisoning, the fire explosion of personnel.
Summary of the invention
For the problems of the prior art, the invention provides a kind of fastening type flange connector, it enables to install between flange more fasten, and reduces the probability of flange seepage.
The technical solution adopted for the present invention to solve the technical problems is: a kind of fastening type flange connector, including upper flange, lower flange, sealing ring and fastening lid.
Described upper flange is provided with an annular flange face and a flange；A described flange face is provided with six bolt holes, and a described flange is positioned at upper end in the middle part of a flange face；
Described lower flange is provided with No. two annular flange faces and No. two flanges；No. two described flange faces are provided with six bolt holes, and No. two described flanges are positioned at lower end in the middle part of No. two flange faces；
Described upper flange is connected by six roots of sensation bolt with lower flange, and is provided with sealing ring between upper flange and lower flange, and described sealing ring is quality of rubber materials；
Described fastening lid includes left cover and right cover, described left cover and right cover are all each provided with three screwed holes, described fastening lid can be arranged on a flange face and No. two flange face peripheries by bolt, and the cross section of described left cover is " [" shape, the cross section of described right cover is "] " shape, described left cover and right cover can form a complete annular chamber and left cover 2-6mm all little of than a flange face, No. two flange faces and sealing ring three height sum the inside wall height of right cover.
During work, being first placed on lower flange by upper flange, be provided with sealing ring, then fastening lid is nested in a flange face and No. two flange face peripheries between upper flange and lower flange, fastening is covered, is bolted between upper flange and lower flange firmly；Due to all little than a flange face, No. two flange faces and the sealing ring three height sum 2-6mm of the inside wall height of fastening lid, so the upper surface at the inwall top and a flange face now fastening lid contacts, contacting with the lower surface of No. two flange faces bottom the inwall of fastening lid, sealing ring is firmly pressed closely simultaneously.The effect of fastening lid is so that between upper flange with lower flange to be connected more closely, so that the leakproof of the present invention is better.
Annular opening groove it is provided with inside described sealing ring, described open slot cross section is triangle, and the inner ring diameter of described sealing ring 4-8mm less of a flange face inner ring diameter and No. two flange face inner ring diameters, during work, hydraulic shock open slot so that the sealing ring extruding upper flange of open slot both sides and lower flange, so that liquid is not easily from upper flange and sealing ring, and seepage is gone out between lower flange and sealing ring so that the good airproof performance that this experiment is novel.
The invention has the beneficial effects as follows:
(1) present invention fastens the design of lid so that be not only connected by bolt between upper flange with lower flange, is also close to Gu Gai and fastens, so that the connectivity robustness of the present invention is higher.
(2) present invention design has the sealing ring of special construction, its sealing ring is provided with open slot, liquid can strut open slot so that sealing ring extrudes flange, and then make the sealing of the present invention better, simultaneously, the sealing ring open slot of the present invention is less, does not have the sealing affecting between flange because sealing ring open slot is relatively big.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
