Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 6, a forgetting-to-press preventing connection pipe with sonar detection function includes a pipe body 1, the pipe fitting body 1 has a first connection port 2 and a second connection port 3 perpendicular to each other, the root of the first connecting port 2 extends to the periphery to form an annular limiting baffle 4, the outer side of the limiting baffle 4 is provided with a guide ring 5, the diameter of the guide ring 5 is gradually reduced from inside to outside, the end part of the first connecting port 2 is hexagonal, a first sealing groove 6 and a second sealing groove 7 are arranged on the inner wall of the second connecting port 3, sealing rings 8 are respectively arranged in the first sealing groove 6 and the second sealing groove 7, the inner wall of second connection port 3 on still seted up through-hole 9, through-hole 9 be located between first seal groove 6 and the second seal groove 7, just the outer end of through-hole 9 is the loudspeaker form.

In this embodiment, the inner wall of the pipe fitting body 1 is provided with a detection bump for matching sonar flaw detection. Because the detection lug protrudes from the inner wall, the fluid flowing through the pipe fitting main body 1 has large impact on the detection lug and high probability of damage and deformation of the detection lug, so that when the sonar flaw detector detects a pipeline, the condition of the detection lug can be preferentially detected, the damaged area is quickly positioned, and then maintenance and replacement operations are performed.

In this embodiment, the detecting bumps include a first detecting bump 10 near the first connection port 2 and a second detecting bump 11 near the second connection port 3, the first detecting bump 10 is triangular, and the second detecting bump 11 is semicircular. Adopt the structure of this embodiment, the shape to the detection lug in different regions has been distinguished and has been set for can be accurate when the sonar is detected a flaw to be the concrete injured position of connecting the pipe fitting, thereby need not to dismantle completely when carrying out further detection and maintenance, only need pull down specific one end external pipe fitting can, it is more efficient to operate.

In this embodiment, the outer wall of the first connection port 2 is provided with a plurality of retaining rings 12 in a protruding manner, the front end faces of the retaining rings 12 gradually rise from front to back, an caulking groove is formed between adjacent retaining rings 12, and the caulking groove is also provided with a sealing ring 8. Through the setting of stopping circle 12 for the external pipe fitting is more firm with being connected of first connection port 2, and the sealed connection of rethread sealing washer 8 and external pipe fitting can further promote the reliability of connecting, and provides sufficient sealing performance.

The impact force applied to the bend of the pipe fitting body 1 is often large, and the directions of the fluids in the pipe fitting body 1 are not consistent, so that the portion of the bend, which is subjected to the impact, is also deviated, and once a certain portion is damaged, the use of the whole pipe fitting is affected. In this embodiment, the pipe fitting further includes a buffering elastic sheet 13, two positioning columns 14 are disposed at the turning position inside the pipe fitting main body 1, springs 15 are respectively sleeved on the positioning columns 14, the buffering elastic sheet 13 is fixedly connected with the springs 15, one positioning column 14 faces the first connection port 2, and the other positioning column 14 faces the second connection port 3. The buffering elastic sheet 13 in the embodiment can play a role in buffering water flow, so that the pipe wall is protected, and the service life is prolonged. The structure of spring 15 is set up respectively to both sides for buffering shell fragment 13 can carry out the self-adaptation regulation according to fluidic flow direction, velocity of flow when using, plays better cushioning effect.

The utility model discloses during the use, earlier put in place sealing washer 8 embedding, will connect external pipe fitting to insert first connection port 2 and second connection port 3 respectively after that, insert first connection port 2 in-process guide ring 5 plays the guide effect to external pipe, stopping circle 12 can prevent external pipe fitting and break away from, then the front end of external pipe is blocked by the baffle and can't continue to insert, accomplishes the assembly of first connection port 2.

The utility model discloses before the pipeline buries wall or ground, can in time discover the problem through the preliminary examination. When detecting that fluid realizes the passageway, if second connection port 3 is connected not closely with external pipe fitting, the fluid can flow into to through-hole 9 and finally flow to the external world to can in time be found and fix a position the problem pipe fitting by the user.
