Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of the utility model pipe joint as Figure 1-4, comprises fittings body 1, gland 2, cutting ferrule 3 and elastomer seal 4; Between described fittings body 1 and described gland 2, adopt and be threaded; The center of described gland 2 offers through hole 204, and the external diameter of the internal diameter of described through hole and pipe fitting 6 is adaptive; In described fittings body 1, offer porosely 101, the external diameter of the internal diameter in described hole 101 and pipe fitting 6 is adaptive, in described hole 101, also offers groove 102, and described groove 102 has been nested with described elastomer seal 4; Between described fittings body 1 and gland 2, be also provided with cutting ferrule 3, described cutting ferrule 3 is set on described pipe fitting 6, the face contacting with described gland 2 on described cutting ferrule 3 is conical surface 301, offers accordingly cone shape hole 203 on gland 2, and described conical surface 301 contacts cooperation with described cone shape hole 203.
As optimization, on the inner ring of described cutting ferrule 3, be provided with slideproof tooth 302, described slideproof tooth 302 can strengthen the frictional force between cutting ferrule 3 and pipe fitting 6, makes to have higher sealability between pipe fitting 6, improves its safety reliability.
As optimization, on the outer wall of described gland 2, be provided with anti-slip tank 202, described anti-slip tank 202 can improve the friction factor on gland 2 surfaces, makes to provide enough frictional force, convenient operation in the process of tightening gland 2.
As optimization, the degree of depth of the cone shape hole 203 on the gland of telling 2 be less than the width of described cutting ferrule 3, in the process of tightening at gland 2, guarantee cone shape hole 203 on gland 2 all the time with cutting ferrule 3 on conical surface 301 laminatings.
As optimization, described elastomer seal 4 is rubber seal, and described rubber seal can improve the sealability between pipe fitting 6, improves its connection reliability.
Specifically, when the utility model pipe joint uses, first gland 2 is set in respectively in the pipe fitting 6 of required connection, and then cutting ferrule 3 is overlapped as in pipe fitting 6 respectively.The cone shape hole 203 of during placement, the conical surface on cutting ferrule 3 301 being aimed on gland 2.Then gland 2 is screwed in fittings body 1, at gland 2, be screwed in the process of fittings body 1, conical surface 301 on 2 pairs of cutting ferrules 3 of gland produces larger pressure, make the slideproof tooth 302 on cutting ferrule 3 inner rings bite pipe fitting 6, and drive pipe fitting 6 toward fittings body 1 internal motion, therefore even there is larger pressure between pipe fitting 6 and elastomer seal 4, can make between pipe fitting 6, to there is good sealability.
The utility model pipe joint just can be realized the connection between required connection pipe fitting by tightening the gland at two ends, simple to operate, and the pipe fitting after connecting has good sealability, has application performance comparatively widely.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
