Description

Flow adjustable connecting tube

technical field

The invention relates to the field of pipe connectors, in particular to a flow-adjustable connecting pipe.

Background technique

The inner diameter of existing connecting pieces used for pipeline connection is generally fixed, without the function of adjusting the inner diameter, correspondingly, the water flow rate passing through the connecting piece cannot be changed. However, in actual use, the flow rate required on the water outlet side is often different, so a regulating valve with adjustable flow rate has to be connected in series in the pipeline on the water outlet side, which increases the cost.

Contents of the invention

In order to solve the above problems, the present invention aims to provide a flow-adjustable connecting pipe with ingenious structure, adjustable flow rate and low cost through structural improvement and optimization.

The technical solution of the flow adjustable connecting pipe is realized in the following way:

The flow-adjustable connecting pipe includes a cylindrical body, the center of the body is provided with a through main flow channel, and the body outside the main flow channel is surrounded by at least one through secondary flow channel;

One end of the body is a coaxial stepped boss, and the other end of the body is flush. The main channel starts from the end face of the stepped boss with the smallest outer diameter. There is a one-to-one correspondence between the roads, and the correspondence starts from the end face of the first-level remaining boss;

The bosses corresponding to the secondary runners are all matched with a turntable, and the turntable penetrates from the boss with a smaller outer diameter among the adjacent two-stage bosses until the end face of the boss matched with the turntable touches. The turntable is provided with a communication hole that matches the auxiliary flow channel on the boss. When the turntable is rotated, the communication hole on it can communicate with the corresponding auxiliary flow channel. In the area of all auxiliary channels, when the turntable is turned to the corresponding angle of this area, the turntable can close the auxiliary flow channels on the corresponding boss;

The turntable is also matched with a fixed ring that limits the sliding of its axis.

Further, a limiting structure is provided on the two abutting end surfaces of the turntable and its corresponding boss, and the limiting structure includes a limiting projection and a limiting groove, which are used to limit the connecting hole on the turntable and the contact hole on the boss. The positional relationship between the turntable and the boss when the sub-runners are connected, and the positional relationship between the turntable and the boss when the turntable rotates to the area where all the sub-runners on the boss can be blocked.

Further, the limit projection is located on the turntable, the limit groove is located on the boss, there is one limit projection, and there are two limit grooves. When the limit projection is combined with one limit groove, the turntable The connecting hole of the connecting hole is connected with the auxiliary flow channel on the boss, and when the limit protrusion is combined with another limit groove, the area on the turntable that can block all the auxiliary flow channels on the boss will block the auxiliary flow channel on the boss. Road off.

Further, a sealing pad is provided on the end surface of the turntable and its corresponding boss, and the position corresponding to the communication hole is hollowed out on the sealing pad to form a through hole.

The adjustable flow connecting pipe is a connecting piece used for connecting two pipelines. During installation, according to the flow requirements of the outlet side after the pipe connection, by adjusting the angle of the turntable, you can choose to open or close the auxiliary flow channel to adjust the flow through the adjustable flow connecting pipe to meet the flow requirements.
