Description

Right-angle corrugated pipe

Technical Field

The utility model relates to a bellows, in particular to right angle bellows.

Background

The corrugated pipe is a tubular elastic sensitive element which is formed by connecting foldable corrugated sheets along the folding and stretching direction. The corrugated pipe has wide application in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thin pipe wall and high sensitivity, and the measurement range is from tens of Pa to tens of MPa. Its open end is fixed, its sealed end is in free state, and its elasticity is increased by using auxiliary helical spring or reed. When working, the pipe is extended along the length direction under the action of internal pressure, so that the movable end generates displacement in a certain relation with the pressure. The corrugated pipe used in the market at present is found to have the following disadvantages in use: 1) the spinning hard seal is needed during installation, and the installation is troublesome; 2) when the straight pipe section of the right-angle corrugated pipe is installed, the straight pipe section needs manual bending and shape adjustment.

Detailed Description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 4, the present invention provides a right-angle corrugated pipe, which includes a corrugated pipe section 1 and a first straight pipe section 2 connected to each other, wherein an axis of the corrugated pipe section 1 is perpendicular to an axis of the first straight pipe section 2, the corrugated pipe section 1 can be straightened to facilitate the shaping of a product, and the right-angle portion is not easy to deform; the other end of the corrugated pipe section 1 is provided with a first pipe joint 4, the other end of the first straight pipe section 2 is provided with a second pipe joint 5, the second pipe joint 5 is provided with a support 3, the support 3 is welded on the second pipe joint 5, and the support 3 is used for fixing the second pipe joint 5.

In order to achieve the purpose of convenient connection, in the present embodiment, the lower end of the first pipe joint 4 is sleeved with a rotating nut 44, an external thread section 41 is arranged on the first pipe joint 4, a second straight pipe section 42 is arranged in the first pipe joint 4, the second straight pipe section 42 extends upwards to the outside, and the upper end of the second straight pipe section 42 is provided with a flange 43; further, the angle a of the turned-up edge 43 is more than or equal to 88.5 degrees and less than or equal to 91.5 degrees, wherein 90 degrees is the best; further, the male screw section 41 has a 3/4-18 screw thread structure, and when the first pipe joint 4 is connected with the connected component in use, the second straight pipe section 42 extends into the pipeline, the outer wall of the flange 43 contacts with the inner wall of the connected component, and is locked by the male screw section 41, and then is further locked with the connecting component by rotating the nut 44.

In order to fix the second pipe joint 5, in this embodiment, a mounting hole 31, a mounting groove 32 and a fixing block 33 are provided on the bracket 3, referring to fig. 4, the mounting hole 31 is a through hole structure and is provided on the left side of the bracket 3, the fixing block 33 is provided on the right side of the bracket 3, and the mounting groove 32 is a waist-shaped groove and is provided at a central position of the bracket 3 near the upper end.

In order to improve the sealing effect, in this implementation, the internal thread section 51 is arranged in the second pipe joint 5, the internal thread section 51 is of a superfine internal thread structure, the superfine internal thread structure is selected for use, the thread self-locking is facilitated, and the leakage can be effectively prevented.
