Abstract

The invention relates to a high-pressure quick-mount flange. The high-pressure quick-mount flange comprises two pairs of welding rings, a locating ring, a lens cushion, two half clamps, a locating bolt, a locating nut, a fastening bolt and a fastening nut, wherein the locating ring is mounted between the two pairs of welding rings; the lens cushion is mounted inside the locating ring; the two half clamps are mounted outside the two pairs of welding rings; one ends of the two half clamps are connected by the locating bolt and the locating nut; and the other ends of the two half clamps are connected in a fastening manner by the fastening bolt and the fastening nut. The high-pressure quick-mount flange provided by the invention has the advantages of easiness in mounting, low cost, simplicity and easiness in purchasing and processing, and easiness in standardizing popularization.

Description

High pressure fast-assembling flange
Technical field
The present invention relates to the detachable isolated plant that a kind of pipeline connects; Relate in particular to a kind of high pressure fast-assembling flange; Its Maximum operating pressure can reach 50MPa; Maximum operating temperature can reach 610 ℃, and applicable to multiple fields such as oil, chemical industry, metallurgy, electric power, boats and ships, nuclear industry, aerospace industries, applicability is very extensive.
Background technique
At present; The connecting mode of industrial pipeline mainly contains direct welding type, scyewed joint formula, flange plate articulated and cutting ferrule articulated; Wherein the flange plate articulated has characteristics such as detachable, high pressure resistant, use the most extensive, but but the shortcoming that the flange plate articulated has be: as pipe diameter big (greater than φ 200mm); Pipeline is important heavier, and relatively difficulty is installed; The moment that bolt needs is bigger, installs also gruelling; Sealing gasket is difficult to location and installation; When pipe deforming, when pipeline has space angle, flange just connects very difficulty (bolt hole is difficult to centering); Because distortion, the flangeseal face just is easy to generate the run, drip, leak phenomenon; Flange plate has a lot of different size system and pressure ratings, and different systems can not be exchanged, so the stock is very big.
And cutting ferrule connects the half chip cutting ferrule that adopts two symmetries; Form through the bolton connection; Compare with the flange plate connecting mode, be easier to install (cutting ferrule can 360 degree rotations, have solved the problem that the flange plate bolt hole is difficult to centering), littler assembling moment, warehousing pressure is also little.But cutting ferrule connects the shortcoming that is had: cutting ferrule is symmetrical half chip, when the big weight of cutting ferrule is heavier, needs to aim at, lift, and just connects very difficulty; Sealing gasket is non-standard Sealing, and processed complex, buying be difficulty, and physical life is short, and cost is higher; Sealing gasket is difficult to install, and comes off easily when cutting ferrule is installed; Shell ring also is non-tender, and sealing surface is nonstandard design, and processing, buying be difficulty, and cost is higher.
Summary of the invention
To above-mentioned shortcoming, the object of the invention is to provide a kind of and is easy to install, cost is low, simply easy, as to be easy to standardized and popularized high pressure fast-assembling flange is processed in buying.
Technology contents of the present invention is: a kind of high pressure fast-assembling flange is characterized in that it comprises two welding neck collars, positioning ring, German-style metal lensring, two halves chip clip, holding down bolt, setscrew nut, clamping bolt and tightening nut; Positioning ring is installed between two welding neck collars; German-style metal lensring is installed in the positioning ring inboard; Two halves chip clip is installed in the two welding neck collars outside; Be connected with the end of setscrew nut through holding down bolt, be fastenedly connected through clamping bolt and tightening nut the other end with two halves chip clip with two halves chip clip.
The advantage that is compared with prior art had of the present invention is:
(1), welding neck collar adopts the standard welding neck collar meet ISO EN1092-1-34, is easy to buying, cost is lower;
(2), seal form adopt standard, use very widely, the high pressure seal with metal lens ring, make it possible to more than the withstand voltage 50MP good sealing effect;
(3), sealing gasket adopts the German-style metal lensring of standard, is easy to buying; Positioning ring can directly form with the thin plate cutting, and cost is lower;
(4), on German-style metal lensring, install positioning ring additional, be convenient between German-style metal lensring location and the welding neck collar, it is easily simple to make German-style metal lensring install, difficult drop-off;
(5), earlier two halves chip clip is connected with setscrew nut through holding down bolt, through clamping bolt and tightening nut securing means is fastened on the welding neck collar then, realizes the connection of pipeline thus, its installation is very simple, singlely just can accomplish.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 be among Fig. 1 A-A to schematic representation.
Specific embodiment
A kind of high pressure fast-assembling flange as depicted in figs. 1 and 2; It is characterized in that it comprises two welding neck collars 1, positioning ring 2, German-style metal lensring 3, two halves chip clip 4, holding down bolt 5, setscrew nut 6, clamping bolt 7 and tightening nut 8; Positioning ring 2 is installed between two welding neck collars 1; German-style metal lensring 3 is installed in positioning ring 2 inboards; Two halves chip clip 4 is installed in two welding neck collars, 1 outside, is connected with the end of setscrew nut 6 with two halves chip clip 4 through holding down bolt 5, is fastenedly connected through the clamping bolt 7 and the other end of tightening nut 8 with two halves chip clip 4.
Connecting means of the present invention is: two welding neck collars 1 are welded with two pipelines that will dock respectively mutually; German-style metal lensring 3 positioning ring 2 of packing into; Again positioning ring 2 is packed between two welding neck collars 1, two halves chip clip 4 is installed in two welding neck collars, 1 outside, be connected with the end of setscrew nut 6 two halves chip clip 4 through holding down bolt 5; Be fastenedly connected through the clamping bolt 7 and the other end of tightening nut 8, realize the quick connection of two pipelines thus two halves chip clip 4.
