Description

Pipe collar

Technical field

The utility model relates to a kind of pipe collar, is a kind of improvement structure of pipe collar specifically, can effectively avoid wearing and tearing, leakage and the maintenance of pipe collar.

Background technique

Pipe collar is applied on the recirculating fluidized bed external bed panel-pipe of heating surface, makes horizontal and vertical row of conduits by the reasonable marshalling unanimity of spacing, plays suspension, spacing and fixation.The pipe collar structure of using in this field at present is integral type, mainly by integrally-built pipe collar and be positioned at the semicircle deck of both sides disjunctor, has with the semicircle deck of both sides disjunctor the semi-circular plate composition that cooperates is installed.During application, integrally-built pipe collar is installed on the pipe tunnel, and the disjunctor semicircle deck of pipe collar body both sides and semi-circular plate are used to install and fix horizontal pipeline, with the binding site welding between disjunctor semicircle deck and the semi-circular plate half.Therefore in the practical application, because the quality of fit of boiler external bed internal heating surface column pipe and pipe collar requires 0.2mm, but the accuracy of manufacturing of pipe collar and pipeline does not reach precision like this, so install in the cooperation and have error, pipe collar is an integral casting forming in addition, causes the matching gap between pipe collar and the pipeline excessive and loosening.In addition, the external bed heating surface piping is arranged and is made up of the coiler of vertical column pipe and level, arranges two groups of heating surface piping rows in each external bed, every group 30 row.The coiler of level is fixed on the vertical suspention pipeline by pipe collar, pipe row interior media is a steam during boiler operatiopn, external agency is high hotbed material, because the percussion of steam inside and outside bed material causes the body vibration of row of conduits when moving, thereby cause pipe collar and the wearing and tearing of suspending the pipeline contact position in midair.When the wear extent of suspention pipeline when reaching the pressure-bearing limit of tube wall, tube wall breaks and causes steam leakage and be forced to blowing out and handle, and each blowing out causes the electric quantity loss of great number to electricity power enterprise.Simultaneously the space is narrow and small in the external bed, and maintenance is difficulty very, and because the special Placement of pipe collar is also given to change row of conduits and pipe collar is installed and caused big difficulty, all needs pipe arranged to break to return dress again and just can finish at every turn, has a strong impact on normal generator operation.

Summary of the invention

In view of above-mentioned present situation, the utility model provides a kind of improved pipe collar, by being designed to adjustable pipe collar, has solved the wearing and tearing of becoming flexible the pipeline that the part is cooperated of pipe collar, thereby has reduced the leakage and the maintenance of pipeline.

Technical solution of the present utility model is: a kind of pipe collar, comprise pipe collar, and the disjunctor semicircle deck of pipe collar body both sides, have with disjunctor semicircle deck the semi-circular plate that cooperates is installed; Wherein said pipe collar is the assemblying body of two split type semi-circular structure, and the pipe collar both sides of each semi-circular structure body have the folder ear, and has attachment hole on the folder ear, connects by bolt.

According to above-mentioned application characteristic, the semi-circular plate independent and configuration of disjunctor semicircle deck is one and is embedded in single semi-circular plate in the disjunctor semicircle deck groove, or semi-circular plate have body wherein the both sides of an end face be provided with the symmetry adjutage, form gap between the two symmetrical adjutages.Like this, the disjunctor semicircle deck that can utilize pipe collar body both sides and semi-circular plate or the semi-circular plate that has an adjutage dock the multiple spot welding of combination back, and the folder ear of the pipe collar both sides of assemblying body, by welding again after the bolt connection, have fixation, not fragile, reduce maintenance.

In a word, the pipe collar that the utility model provides is the split composite structure by the overall improvement to pipe collar, can regulate according to the difference of caliber when therefore installing, so low to the required precision of caliber, applicability is strong.In addition,, also improve, increased the adjutage of semi-circular plate both sides, strengthened the fixation of semi-circular plate, have installation, maintenance is convenient, has improved working life for the structure of the semi-circular plate of horizontal pipe collar.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is another embodiment's schematic representation of Fig. 1 semi-circular plate;

Fig. 3 is application reference embodiment's schematic representation of Fig. 2 and the combination of Fig. 1 pipe collar.

Embodiment

The utility model is further described below in conjunction with accompanying drawing embodiment.

See pipe collar shown in Figure 1, comprise the disjunctor semicircle deck 2 of pipe collar 1 and pipe collar 1 body both sides, have with disjunctor semicircle deck 2 semi-circular plate 3 that cooperates is installed.In the present embodiment, described pipe collar 1 is the assemblying body of two split type semi-circular structure, and pipe collar 1 both sides of each semi-circular structure body have folder ear 4, and the attachment hole 5 that has on the folder ear 4, is fastenedly connected by bolt 6 insertion attachment holes 5 to be integral.In this is novel, be 90 ° between described disjunctor semicircle deck 2 and the pipe collar 1, pipe collar 1 is used for fixing pipe tunnel, and the semi-circular plate 3 of disjunctor semicircle deck 2 and split is used for fixing horizontal pipeline when making up.During this new application, the pipe collar 1 of two semi-circular structure bodies is buckled in pipe tunnel, by on the pipe collar 1 both sides folders ear 4 with bolt 6 fastening after, fixing by the docking site welding of pipe collar 1 both sides folder ear 4 again, utilize on the disjunctor semicircle deck 2 of pipe collar 1 both sides horizontal pipeline is installed after, semi-circular plate 3 is buckled on the pipeline, after making its two ends and disjunctor semicircle deck 2 grooves being connected, more up and down abutting end weld promptly finish fixing.

Fig. 2 has provided the semi-circular plate different with Fig. 1.Different is that semi-circular plate 3 bodies wherein have symmetrical adjutage 7 in the both sides of an end face, by forming gap between 7 of symmetrical adjutages and the semi-circular plate 3.

When the semi-circular plate among Fig. 23 makes up with disjunctor semicircle deck 2, has the fixation of strengthening semi-circular plate 3 by adjutage 7.This scheme is better than semi-circular plate single among Fig. 13.

Provided the application reference embodiment of Fig. 2 and 1 combination of Fig. 1 pipe collar by Fig. 3.Same pipe collar 1 and the disjunctor semicircle deck 2 thereof of adopting selected the semi-circular plate 3 and its combination that have adjutage 7 among Fig. 2 for use.Therefore, on wherein adjutage 7 parts of the semi-circular plate 3 of a side are positioned at during use, utilize semi-circular plate 3 to combine the back welding with disjunctor semicircle deck 2, and disjunctor semicircle deck 2 parts are positioned at the gap of adjutage 7; On the contrary, adjutage 7 parts of the semi-circular plate 3 of opposite side are positioned at the lower end, same semi-circular plate 3 combines the back welding with disjunctor semicircle deck 2, and disjunctor semicircle deck 2 parts are positioned at the gap of adjutage 7, again the adjutage 7 of both sides and the upper and lower end of semi-circular plate 3 parts each other are welded to one another fixation.

In the present embodiment, described pipe collar 1 integral body is made up of two-part symplex structure body, and adopts machinery type to link into an integrated entity 90 ° of configurations each other each other.Therefore, have the required precision of caliber lowly, applicability is strong, has changed method of clamping, installs simply, and matching gap is adjustable, can regulate according to actual size, satisfies installation requirement.Pipe collar uses the foundry goods of 1Cr20Ni14Si2 material, has improved serviceability temperature, heatproof height, long service life.
