Description

The pipe branch pipe clamp

Technical field:

The utility model relates to a kind of pipeline bindiny mechanism, especially a kind of pipe branch pipe clamp.

Background technique:

At present, in town water supply, coal gas and petroleum chemical industry, use the line transportation medium.When needs were set up branch line, common way was: at first stop the medium transport of main pipe inside, then, cut off a section in the main pipe, three-way pipe is installed therein, drawing of branched pipe of enforcement connects.The deficiency that it exists is, should stop the medium transport of pipeline, is not suitable for pipe first-aid in case of emergency; Inconvenient operation again, the installation process complexity.

The content of model utility:

The purpose of this utility model provides under a kind of situation that does not stop fed sheet of a media at pipe interior draws the pipe branch pipe clamp that connects branch line.

Concrete scheme of the present utility model is: design a kind of pipe branch pipe clamp, comprise pipe clamp, down pipe clamp and attachment bolt, its key is: A. has through hole with the pipe clamp axis normal at the arc end face of last pipe clamp, and seal ring is housed in the bottom of through hole; B. descend the inner arc surface of pipe clamp to be provided with at least two cambered surface boss with pipe clamp perpendicular bisector symmetry.

The described through hole of going up pipe clamp is positioned at pipe clamp end face middle part, and its throughhole portions is extended outside arc tube wall, and its terminal point has mountion plate, on this platform mounting hole is arranged.

Described seal ring simultaneously is a smooth surface, and one side is a toothed surfaces, and the tooth on this toothed surfaces is by circumferentially and laterally distributing alternately, and its smooth surface amplexiforms the inner tube wall in the via bottoms of last pipe clamp.

The utility model is arranged on down the cambered surface boss of pipe clamp inwall, and the angle of its center line and pipe clamp perpendicular bisector is 35 °～55 °.Optimum angle is 45 °.

The described length of pipe clamp down is 1/3～1/2 of last pipe clamp length.Below last pipe clamp, be connected with at least 2 following pipe clamps side by side by bolt.

In the as installed process, at first upper and lower pipe clamp is fixed on the main pipe with Bolt Connection, main pipe is not stopping under the interior media conveying situation, need not disconnect main pipe, use and management perforator (known equipment), size corresponding through hole of leaving on main pipe along the hole of opening on the last pipe clamp, this hole size is draws the caliber size that connects bye-pass, then the standard gate valve is connected on the mountion plate (flange plate) of pipe clamp upper end, promptly having finished drawing of whole branch line connects stand-byly at any time, has replaced the three-way pipe in the conventional construction.

Adopt the beneficial effect of such scheme to be:

1. be connected with the standard gate valve after the perforate owing to the utility model is installed on the main pipe, and use the sealed type perforator, main pipe delivered inside medium can not overflow, thereby the interior media that need not stop main line being carried.

2. only need be fixed in main pipe on and perforate by Bolt Connection upper and lower pipe clamp during owing to use, thereby, do not need to disconnect main pipe, thereby have characteristics easy for installation, simple to operate.

3. owing to descending on the pipe clamp inner arc surface having the cambered surface boss of two symmetries to make the strong point not easy-rupturing, the damage of following pipe clamp.

4. because two symmetrical boss strong points on the following pipe clamp inner arc surface and last pipe clamp sealing part form the principle of three points centering, no matter main pipe circumference what state, pipe clamp integral body the phenomenon that is shifted can not occur.

5. because the rubber seal in the last pipe clamp adopts dentation structure, therefore fit closely with main pipe, sealability is better.

Below in conjunction with drawings and Examples the utility model is further specified.

Description of drawings:

Fig. 1 is a plan view of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the plan view of seal ring 4 among Fig. 1;

Fig. 4 is the whole-cutaway view of Fig. 3.

Embodiment:

Please see Figure 1, Fig. 2, the utility model mainly by last pipe clamp 1, connect that spiral shell is complete 2, pipe clamp 3, seal ring 4 are formed down.Wherein A. has through hole 5 with the pipe clamp axis normal at the arc end face of last pipe clamp 1, in the bottom of through hole 5 seal ring 4 is housed; B. descend the inner arc surface of pipe clamp 3 to be provided with at least two cambered surface boss 6 with pipe clamp perpendicular bisector symmetry.

The described through hole 5 of going up pipe clamp 1 is positioned at pipe clamp end face middle part, and its through hole 5 parts are extended outside arc tube wall, and its terminal point has mountion plate, and mounting hole 8 is arranged on this platform.

As shown in Figure 3, Figure 4: described seal ring 4 one sides are smooth surfaces, one side is a toothed surfaces, tooth on this toothed surfaces distributes alternately by circumferential 10 and horizontal 9, and transverse teeth 9 is separated into several sections with circumferential tooth 10, and its smooth surface amplexiforms the inner tube wall in through hole 5 bottoms of last pipe clamp 1.

As shown in Figure 1: be arranged on down the cambered surface boss 6 of pipe clamp 3 inwalls, the angle of its center line and pipe clamp perpendicular bisector is 35 °～55 °.

Described cambered surface boss 6, preferably 45 ° of the angles of its center line and pipe clamp perpendicular bisector.

As shown in Figure 2: the length of following pipe clamp 3 is 1/3～1/2 of last pipe clamp 1 length.Below last pipe clamp 1, be connected with at least 2 following pipe clamps 3 side by side by bolt 2.

Pipe clamp 1 and 3 combinations of following pipe clamp are close to main pipe 7 outer walls on the utility model, and be connected and fixed by bolt 2, the axis of the through hole of being opened on the last pipeline 15 and pipe clamp axis and main pipe 7 intersect vertical axis, and the diameter in the hole of opening equates with the required caliber that connects branched pipe that draws.Following pipe clamp 3 has at least two to connect (as Fig. 2) with last pipe clamp 1 according to the required caliber size that connects branch line of drawing.Generally drawing the caliber that connects branch line is that two following pipe clamps 3 connect below 200mm, and 200mm is above to be that three or more pipe clamps down connect.With pipe clamp 3 inner arc surfaces at present along about the perpendicular bisector each 45 ° arrange two cambered surface boss 6, this boss is close to main pipe 7, becomes two strong points of pipe clamp 3 down.These two strong points and last pipe clamp sealing part form three points location.
