Description

Saddle

Technical field:

The utility model relates to a kind of Saddle.Be used for connecting branch road on main line.

Background technique:

Usually on main line, use threeway connecting branch road, to realize the fluid shunting.Because common threeway outer wall is cylindrical body, from be responsible for to the arm filtration zone to threeway in fluid pressure produce the stress concentration phenomenon; The threeway wall thickness is identical, and the stress distribution when pressing in being subjected to pipe is incompatible, and pipeline easily breaks when pressing in pipe is subjected to fully; The threeway inner chamber is the cylindrical body passage, and fluid stress when being responsible for arm is more concentrated, therefore needs to adopt the special threeway of large scale, big wall thickness.The special threeway size of this class is bigger, be difficult to make and cost higher, the bye-pass site operation is difficulty again, needs persons in charge cut off to reserve the threeway link position and embed threeway again and connect, and is connected with the pipe fitting of branch line and has only a kind of form of butt welding, the connection inconvenience.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of and can replace threeway, and volume little, easy for installation, be easy to construction operation, cost of production low, with branch line connecting branch road Saddle easy to connect.

Technical solution of the present utility model is: a kind of Saddle, be characterized in adopting the design of equal area reinforcement method, it comprises the Saddle body, Saddle body outer wall is cone, play the effect of reinforcement, Saddle has carried out thickness compensation from being responsible for to the varied in thickness of arm filtration zone to the stress concentration phenomenon that liquid in pipe pressure produces; Saddle body outer wall lower end is provided with the ring-type groove, the different in width of Saddle body outer wall lower end and the side bevel for welding of being responsible for the joint, and the stress distribution when pressing in being subjected to pipe is corresponding, and pipeline does not break during pressure in pipe is subjected to fully; The Saddle chamber body is provided with the cone passage, makes fluid from being responsible for arm a gradually closing transition be arranged, and relaxes the phenomenon that stress is concentrated greatly, has improved flowing of fluid.

In the design and installation of pipeline, use Saddle and use threeway to compare, have the following advantages:

1, pipeline, installation and design conveniently are easy to construction operation

When using threeway, need calculate position and the distance of reserving threeway on the pipeline during circuit design, and use Saddle just not need to consider the problem of branch;

2, lower engineering cost

The cost of same specification Saddle only is 10～50% of a common threeway cost;

3, speed of application is fast

Utilize Saddle to make main line branch, the construction welding capacity only is 1/10～1/5 of threeway;

4, be connected more convenient with the accessory of branch line

Threeway branch only connects just a kind of form of butt welding, and Saddle branch is connected with socket weld, is threaded that be connected three kinds of forms with butt welding available;

5, manufacturing cycle weak point, delivery rate is fast.

6, volume is little.

Description of drawings:

Fig. 1 is 90 ° of structural drawing when being connected for Saddle of the present utility model and main line.

Fig. 2 is the side view of Fig. 1.

Structural drawing when Fig. 3 is connected for Saddle of the present utility model and main line are 45 ° of angles.

Fig. 4 is the structural drawing of Saddle of the present utility model when being connected with elbow.

Embodiment:

As Fig. 1～2, the utility model is a kind of Saddle that is used for connecting branch on the main line, comprise Saddle body 1, Saddle body 1 outer wall is cone 2, Saddle body 1 outer wall underpart is provided with ring-type groove 3, be weldingly connected with the person in charge 5, Saddle body 1 inner chamber bottom is provided with cone passage 4.Saddle body 1 adopts rod iron to be made through machining.

As Fig. 3, connect needs according to pipeline, the utility model also can be made 45 ° of Saddles.The 45 ° of Saddles and the person in charge are 45 ° of angles, and alternative skew T uses.

As Fig. 4, connect needs according to pipeline, the utility model also can be made into elbolet, and the person in charge who is connected with elbolet is an elbow.

When Saddle is installed, earlier main line 5 is cut a hole, Saddle is placed in is responsible on 5, the hoop groove and the person in charge along Saddle after aligning are welded to connect, after being responsible for welding, again Saddle is connected (comprise butt welding, socket joint connection and be threaded) with arm 6.

Claims (1)

1, a kind of Saddle is characterized in that comprising Saddle body (1), and Saddle body (1) outer wall is cone (2), and Saddle body (1) outer wall lower end is provided with ring-type groove (3), and Saddle body (1) inner chamber is provided with cone passage (4).
