Description
Technical Field
[0001] The utility model relates to the technical field of pipe connection joints, and particularly relates to a carbon steel pipe connection joint with double crimping and leak prevention Background Art
[0002] At present, when a pipe connection joint is connected to a pipe, a crimping method is increasingly used to connect the two. That is, the existing pipe connection joint includes a pipe fitting body and a sealing ring. An annular protrusion protruding outward in the radial direction of the pipe fitting body is provided on the side wall of the pipe fitting body. An annular groove is formed inside the annular protrusion. The sealing ring is embedded in the annular groove. When one end of the pipe is inserted into the end of the pipe fitting body, the inner peripheral wall of the sealing ring can be in close contact with the outer peripheral wall of the pipe and seal circumferentially. In addition, when the pipe fitting body located at the annular protrusion and the pipe fitting body inside the annular protrusion are crimped by a crimping tool, the pipe fitting body can hold the end of the pipe tightly, and the sealing ring can be in close contact with the pipe fitting body and the pipe to seal, so as to realize the connection and fixation of the pipe fitting body and the pipe and achieve the purpose of circumferential sealing. However, in the actual construction process, due to the large number of pipe fitting bodies and pipes, the situation of missed crimping of the pipe fitting body often occurs. And in the existing structure, the inner peripheral wall of the sealing ring itself is in contact with the outer peripheral wall of the pipe and has a certain sealing effect. Therefore, after the pipe is filled with water, there will be a situation where the leakage at the connection between the missed-crimped pipe fitting body and the pipe is not obvious, that is, there is a disadvantage that the installer cannot timely find the position of the missed crimping. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a carbon steel pipe connection joint with double crimping and leak prevention, which can facilitate the installer to quickly and easily find the missed-crimped part, so as to facilitate the installer to re-crimp the missed-crimped part.
[0004] The utility model provides a carbon steel pipe connection joint with double crimping and leak prevention, including a pipe fitting body and a sealing ring. An annular protrusion protruding outward in the radial direction of the pipe fitting body is provided on the side wall of the pipe fitting body. An annular groove is formed inside the annular protrusion. The sealing ring is embedded in the annular groove. When one end of the pipe is inserted into the end of the pipe fitting body, the inner peripheral wall of the sealing ring is used to be in close contact with the outer peripheral wall of the pipe and seal circumferentially. A plurality of notches evenly distributed circumferentially are provided on the inner peripheral wall of the sealing ring. When the end of the pipe fitting body is not crimped, a channel for water to flow through is formed between the notches and the outer wall of the pipe.
[0005] After the present utility model adopts the above structure, since a number of notches evenly distributed circumferentially are provided on the inner peripheral wall of the sealing ring, when the end of the pipe fitting body is not clamped, a channel for water to flow through is formed between the notch and the outer wall of the pipe. Thus, when there is a situation of missed clamping between the pipe fitting body and the pipe, when the pipe is filled with water, the water in the pipe can flow out through the channel formed between the notch and the outer wall of the pipe, which is convenient for the installer to quickly and easily find the position of missed clamping, so as to re-clamp the position of missed clamping.
[0006] In a possible implementation manner, an annular step is provided in the end of the pipe fitting body, and one end of the pipe abuts against the annular step to limit the pipe fitting body and the pipe; through the setting of the annular step, after one end of the pipe is inserted into the end of the pipe fitting body, one end of the pipe can abut against the annular step to limit the pipe fitting body and the pipe, that is, the depth of the pipe inserted into the pipe fitting body can be limited, which brings convenience to the connection between the pipe and the pipe fitting body.
[0007] In a possible implementation manner, an extended straight section is provided on the end of the pipe fitting body, and the extended straight section extends away from the pipe fitting body along the axial direction of the pipe fitting body, and one end of the pipe is inserted into the pipe fitting body through the extended straight section; through the setting of the extended straight section, first of all, after one end of the pipe is inserted into the pipe fitting body through the extended straight section, the inner wall of the extended straight section can be attached to the outer wall of the pipe, that is, the extended straight section can play a supporting role for the pipe body, that is, it can ensure the coaxiality between the pipe and the pipe fitting body, thus avoiding the situation of skewed pipe insertion between the pipe and the pipe fitting body, and avoiding the situation that the end of the pipe damages the sealing ring during the pipe insertion process. In addition, after one end of the pipe is inserted into the pipe fitting body, the installer can clamp the extended straight section and the pipe fitting body inside the annular protrusion, that is, the purpose of double-sided clamping can be achieved, so as to achieve the purpose of double protection and improve the anti-pulling ability of the pipe and the pipe fitting body.
