Socket joint type adjustable angle elbow
Technical field
The utility model relates to a kind of spigot-and-socket connecting pipe fitting, particularly socket joint type adjustable angle elbow.
Background technique
At present, building water supply and drainage system pipeline is used for socket joint connection.Its pipe fitting angle is 45 degree, 90 degree two fixed angles, when the mutual angle of tubing to be connected to some extent deviation time can give in-site installation personnel bring inconvenience.Especially, when underground laying formula pipe angle produces deviation, speed of application can be had a strong impact on.
Model utility content
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, socket joint type adjustable angle elbow reasonable in design, easy to use, this pipe fitting can within the scope of 0-135 degree free adjustment angle, avoid answering tubing relative angle deviation and cause construction inconvenience.
For achieving the above object, the technical solution adopted in the utility model is:
Socket joint type adjustable angle elbow described in the utility model, it comprises arc short tube and the pipe fitting with arc bellmouth or socket; The arc radius of the described pipe fitting with arc bellmouth or socket equals arc short tube radius, and pipe fitting one end is connected with arc short tube, and the other end is connected with tubing; Regulate arc short tube length, the angle of one piece elbow can be changed.
The utility model is made up of three parts, comprising:
One end is ordinary straight shape bellmouth, and one end is the pipe fitting two of arc bellmouth;
Radian is the arc short tube one of 180 degree;
Can need to regulate arc short tube length according to scene in construction, thus reach the object regulating pipe fitting angle.
After adopting said structure, the utility model beneficial effect is: socket joint type adjustable angle elbow described in the utility model, can while connecting tube, and reduce or ignore the difficulty of construction increased because pipeline relative angle is different, structure is simple, easy to operate.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, Figure 2, Figure 3 shows, it comprises arc short tube and the pipe fitting with arc bellmouth or socket; The arc radius of the described pipe fitting with arc bellmouth or socket equals arc short tube radius, and pipe fitting one end is connected with arc short tube, and the other end is connected with tubing; Regulate arc short tube length, the angle of one piece elbow can be changed.
The utility model is made up of three parts, comprising:
One end is ordinary straight shape bellmouth, and one end is the pipe fitting two of arc bellmouth;
Radian is the arc short tube one of 180 degree;
In the utility model, it is noted that in Fig. 1, L1=L2=H is the existing socket pipe member bellmouth degree of depth; In Fig. 1 and Fig. 2, R2=R1+D, D are outer diameter tube to be connected, and R1 is arc short tube inner circle radius;
Can need to regulate arc short tube length according to scene in construction, thus reach the object regulating pipe fitting angle.
Arc short tube inner circle radius formula in the utility model is: 3.14*2*R1=L1 (∠ A/360 degree), wherein, gets ∠ A≤22.5 degree.Now, pipe fitting angle is 0-135 degree.
Socket joint type adjustable angle elbow described in the utility model, can while connecting tube, and reduce or ignore the difficulty of construction increased because pipeline relative angle is different, structure is simple, easy to operate.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim
