Abstract
The utility model relates to a convenient connection type pipe joint convenient and quick to use, which structurally includes that a cutting ferrule is opposite to an external thread coupling sleeve,a lock nut sleeved on the cutting ferrule is in threaded connection with the external thread coupling sleeve, the external end openings of the cutting ferrule and the external thread coupling sleeve are unthreaded holes, and sealing rubber rings are in interference fit with and inserted inside the internal end openings of the cutting ferrule and the external thread coupling sleeve. The convenientconnection type pipe joint realizes sealing connection of pipes by means of magnitude of interference of radial engagement size of the sealing rubber rings, has simple structure and good sealing performance, does not require sealing measures of wrapping hemp threads or gluing and the like, does not need the operation of processing threads on pipes, and has convenient, quick and labor-saving construction.
Description
Technical field
The utility model relates to a kind of pipe joint, specifically a kind of convenient jointing pipe joint.
Background technique
Union (doing " oil is appointed " again) is a kind of pipe joint commonly used, its structure includes cutting ferrule, outside thread joint sleeve and locknut, wherein the external port of cutting ferrule and outside thread joint sleeve all is shaped on internal thread, cutting ferrule is relative with the end face of outside thread joint sleeve, and the locknut that is socketed on the cutting ferrule is threaded with the outside thread joint sleeve.Connecting the essential work of two tubes with union, is to need the termination of the pipes of butt joint make outside thread respectively at two, so that be threaded with cutting ferrule and outside thread joint sleeve on the union respectively.And, also need manual manufacture at present mostly in the externally threaded work of pipe termination system, not only labor intensity is big, and pipe also will take to twine seal approach such as fiber crops or gluing with being threaded of cutting ferrule and outside thread joint sleeve, to prevent seepage.
The model utility content
The purpose of this utility model just provides a kind of convenient jointing pipe joint, to solve the inconvenience of using union to exist.
The utility model is achieved in that a kind of convenient jointing pipe joint, cutting ferrule is relative with the outside thread joint sleeve, the locknut that is socketed on the cutting ferrule is threaded with the outside thread joint sleeve, institute's improvements are that the external port of described cutting ferrule and described outside thread joint sleeve is the light mouth, are plugged with the O-ring seal of interference fit in the inner port of described cutting ferrule and described outside thread joint sleeve.
The usage mode of this pipe joint and the usage mode of union are basic identical, just need not make screw thread again at the position, termination of two tubes, but light pipe is inserted respectively in the O-ring seal in cutting ferrule and the outside thread joint sleeve, the locknut that will be socketed in again on the cutting ferrule is threaded with the outside thread joint sleeve, relies on the magnitude of interference of O-ring seal radial fit size to realize being tightly connected of pipe.
The utility model is equipped with taper type closing in section in the inboard of described cutting ferrule and described outside thread joint sleeve, so that the O-ring seal in cutting ferrule and the outside thread joint sleeve is implemented barrier effect, prevent from.
The utility model is simple in structure, good airproof performance, and pipe need not twine seal approach such as fiber crops or gluing, the operation that need not make screw thread on pipe, easy construction, quick, laborsaving with cooperating of cutting ferrule and outside thread joint sleeve.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the profile of the corresponding component of the cutting ferrule 1 of this convenient jointing pipe joint and the profile of outside thread joint sleeve 5 and existing union is basic identical, just the external port of cutting ferrule 1 and outside thread joint sleeve 5 is the light mouth, in the inner port of cutting ferrule 1 and outside thread joint sleeve 5, be plugged with the O-ring seal 2 of interference fit, locknut 4 is socketed on the cutting ferrule 1, is threaded with outside thread joint sleeve 5.Be provided with taper type closing in section 6 in the inboard of cutting ferrule 1 and outside thread joint sleeve 5.A packing ring 3 also can be set, to improve sealability between the interior edge face of cutting ferrule 1 and outside thread joint sleeve 5.
Claims (3)
1, a kind of convenient jointing pipe joint, cutting ferrule (1) is relative with outside thread joint sleeve (5), the locknut (4) that is socketed on the cutting ferrule (1) is threaded with outside thread joint sleeve (5), the external port that it is characterized in that described cutting ferrule (1) and described outside thread joint sleeve (5) is the light mouth, is plugged with the O-ring seal (2) of interference fit in the inner port of described cutting ferrule (1) and described outside thread joint sleeve (5).
2, convenient jointing pipe joint according to claim 1 is characterized in that being provided with in the inboard of described cutting ferrule (1) and described outside thread joint sleeve (5) the taper type section (6) that closes up.
3, convenient jointing pipe joint according to claim 1 and 2 is characterized in that being provided with packing ring (3) between the interior edge face of described cutting ferrule (1) and described outside thread joint sleeve (5).
