Abstract
The utility model relates to a solderless corrosion-proof flange which is a pipe connector. The utility model mainly comprises dimidiate clamping flanges, double-layer irregular sealed washers, metal guiding washers, steel plastic composite pipe sleeves, fastening bolts and connecting bolts. The utility model is characterized in that both ends of each pipe are respectively provided with the dimidiate clamping flanges which are fastened by the fastening bolts, and both ends of each pipe are respectively sheathed with one metal guiding washer, one double-layer irregular sealed washer and one steel plastic composite pipe sleeve; the dimidiate clamping flanges on both sides of each pipe are fastened and connected by the connecting bolts. The utility model has the advantages of convenient mounting and dismounting, corrosion prevention and good tightness, and has no soldered joint.
Description
The anticorrosion flange of solderless is a kind of pipe coupler.
In existing pipeline connected, adopt following three kinds of connection forms usually: a kind of was scyewed joint, and also having a kind of is that the pipe end welded flange connects.Having a kind of again is that the pipeline butt welding connects, but these connecting modes complex process in actual fabrication, the manufacture cost height, and the installation and maintenance process is very inconvenient, and the connection place easily produces leakage, and national wealth, life safety, environmental protection etc. are brought harmful effect.
The purpose of this utility model just provides a kind of simple in structure, adorns, tears open easy to maintenance, and cost is low, the anticorrosion flange of the solderless of good seal performance.
The anticorrosion flange of the utility model solderless mainly comprises: split clamping flange, double-deck combined special-shaped seal washer, metal guiding collar, steel-plastic composite pipe cover, tight fixed bolt, attachment bolt.It is characterized in that: be equipped with at the two ends of two pipelines adopt tight fixed bolt fastening split clamping flange, and on the two ends of two pipelines, respectively be set with the double-deck combined special-shaped seal washer of a metal guiding collar and a group, also be set with the steel-plastic composite pipe cover, the clamping flange of splitting on pipeline both sides tightened up connection by attachment bolt.Splitting clamping flange is to be made of two semicircle flanges, is provided with connecting hole and tightening hole on semicircle flange; Double-deck combined special-shaped seal washer be by cylindrical and swallow-tail form abnormity combined seal ring combined complete on pipeline; The metal guiding collar adopts metal material processing to become interior right angle type, and the steel-plastic composite pipe cover adopts seamless steel pipe and polyvinyl chloride pipe to be composited.Double-deck combined special-shaped seal washer selects for use fluorine rubber to make, can corrosion protection, and high temperature resistant, also can select suitable tartan etc. for use according to the characteristics of pipeline internal medium; The combination of two kinds of difformity seal rings can further improve sealing effect; Steel-plastic composite pipe cover or Stainless Steel Tube cover have identical with pipeline withstand voltage, heatproof, corrosion resistant ability; Tight fixed bolt is splitting the pipe ends that clamping flange is fixed on needs connection, the right and left split clamping flange by attachment bolt fastening, make the steel-plastic composite pipe in the middle of the flange overlap the guiding position that enters the metal guiding collar with the double-deck combined special-shaped seal washer on both sides, double-deck combined special-shaped seal washer is stressed does the time spent to rapid swollen the rising of pipeline and steel-plastic composite pipe cover two ends, reaches the effect of quick-sealing.
Advantage of the present utility model: the utility model novel and reasonable structure, owing to be provided with and split clamping flange, double-deck combined special-shaped seal washer, metal guiding collar, steel-plastic composite pipe cover, tight fixed bolt, attachment bolt, by connecting with the combination of pipeline, thereby reach solderless knot, corrosion protection, the effect of good seal performance.To having brought very big convenience in inflammable, explosive deathtrap installation, maintenance.
Embodiment of the present utility model is described further as follows in conjunction with the accompanying drawings: accompanying drawing 1 is the structural representation of the anticorrosion flange of solderless; Accompanying drawing 2 is structural representations of splitting clamping flange of the anticorrosion flange of solderless.
Shown in accompanying drawing 1: split clamping flange 1; Split clamping flange 2; Tight fixed bolt 3; Tight fixed bolt 4; Split clamping flange 5; Split clamping flange 6; Attachment bolt 7; Pipeline 8; Pipeline 9; Double-deck combined special-shaped seal washer 10; Double-deck combined special-shaped seal washer 11; Steel-plastic composite pipe cover 12; Metal guiding collar 13; Metal guiding collar 14; Corrosion-resistant pad 15.
Shown in accompanying drawing 2: semicircle flange 1; Pipeline 2; Tight fixed bolt 3; Semicircle flange 4; Attachment bolt is used hole 5.
Example 1, with reference to shown in the accompanying drawing 1:
Tight fixed bolt 3 (two), 4 (two) are separately fixed at pipeline 8,9 both sides splitting clamping flange 1,2 and 5,6 respectively, then metal guiding collar 14,13 and double-deck combined special- shaped seal washer 10,11 are enclosed within pipeline 8,9 both sides respectively, and near the clamping flange of splitting on both sides, pipeline 8,9 is inserted in respectively in the steel-plastic composite pipe cover 12, uses attachment bolt 7 (four) to connect the clamping flange of splitting on both sides fastening then.
Example 2, with reference to shown in the accompanying drawing 1:
If 8,9 steel-plastic composite pipes of the pipeline among the figure, for preventing the outer metal layer of ducted dielectric corrosion steel-plastic composite pipe, before pipeline 8,9 is inserted in 12 li in steel-plastic composite pipe cover respectively, corrosion-resistant pad 15 is bonded on the end face of pipeline 8 or pipeline 9 with special seal cream, in case pad comes off, example 1 is pressed in remaining installation.
Example 3, with reference to shown in the accompanying drawing 1:
If pipeline 8,9 among the figure is during on one side for threeway, four-way, elbow or special pipe etc., only needs on the interface of part welding in advance or connects the adapter of certain-length, can reach the effect of example 1, example 2.
