Description

A kind of pipe joint

Technical field

The utility model belongs to tubular union, is specifically related to a kind of pipe joint.

Background technique

Pipe joint is applied to the connection between multiple tubing element, connects normal heat-melting butt-joint, the steel of adopting mould the Placements such as connection for the pipe of PE pipe, and the needed operation of heat-melting butt-joint mode is comparatively loaded down with trivial details, and technological requirement is high.Steel is moulded connection needs to adopt the methods such as flange, screw thread to connect, and needs larger fastening force, otherwise be difficult to realize good sealability during connection.

Model utility content

(1) technical problem that will solve

The technical problems to be solved in the utility model is to provide a kind of simple in structure easy to operate, can realize interconnective pipe joint between the pipe fitting with diameter, and makes the pipe fitting after connection have higher sealability.

(2) technological scheme

For solving the problems of the technologies described above, the utility model provides a kind of pipe joint, comprises fittings body, gland, cutting ferrule and elastomer seal; Between described fittings body and described gland, adopt and be threaded; The center of described gland offers through hole, and the internal diameter of described through hole and the external diameter of pipe fitting are adaptive; In described fittings body, offer porosely, the internal diameter in described hole and the external diameter of pipe fitting are adaptive, also offer groove in described hole, and described groove has been nested with described elastomer seal; Between described fittings body and gland, be also provided with cutting ferrule, described cutting ferrule is set on described pipe fitting, and the face contacting with described gland on described cutting ferrule is conical surface, offers accordingly cone shape hole on gland, and described conical surface contacts cooperation with described cone shape hole.

Wherein, on the inner ring of described cutting ferrule, be provided with slideproof tooth.

Wherein, on the outer wall of described gland, be provided with anti-slip tank.

Wherein, the degree of depth of telling the cone shape hole on gland is less than the width of described cutting ferrule.

Wherein, described elastomer seal is rubber seal.

(3) beneficial effect

Compared with prior art, 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.

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.
