Abstract
The utility model relates to an internal spring type sealing joint which is characterized in that the internal spring type sealing joint is connected by a nut 2 and a joint body 6. The nut is twisted to tightly press the pipe head 1. A connecting position of the nut 2 and the pipe head 1 is provided with a spring 3 and a metal pad 4. The elastic force of a spring 3 is used for make sealing property better, and simultaneously the loosing and retreating of the nut is effectively avoided. The internal spring type sealing joint has the advantages of long sealing effect keeping and good sealing performance. The internal spring type sealing joint can be used for a separate type air conditioner joint or other joints using sealing connection.
Description
The utility model relates to a kind of internal spring type SEALING FITTING that pipeline connects that is used for.
Pipeline connects the joint of usefulness at present, all be after adopting nut to tighten, the compressing tube head is connected sealing with joint, in use, owing to tube head because of vibrating or reason such as external force effect, make the joint of original sealing progressively leak, such as the joint of separate type air conditioner, the material in the pipeline produces and leaks, and one can influence the normal operation of machine, if the object in two pipelines is harmful to, also can cause environmental pollution.
The purpose of this utility model just provides a kind of good seal performance, the internal spring type SEALING FITTING that sealing effect is lasting.
Solution of the present utility model is such: be provided with spring 3 and metal gasket 4 at former Female connector fittings 2 with tube head 1 convex shoulder joint, compressing pipe joint again behind the nut holddown spring 3 when making installation seals, in the use, because the elastic force effect of spring 3 makes under the lashing force of original nut, has increased elastic force and has acted on the tube head 1, when situations such as the impact that occurs in the use, vibration occur, elastic force can compress tube head 1 automatically, and nut can not moved back by pine, thereby keeps the sealability of joint.
The utility model has the advantages that and to keep sealing effect, good seal performance for a long time.
Accompanying drawing is embodiment of the present utility model:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of cone seal.
The utility model is to be connected with fittings body 6 by nut 2, compresses tube head 1 by nut 6, is provided with spring 3 and metal gasket 4 in nut 6 and tube head 1 convex shoulder joint, and spring 3 can be the single-leaf spring pad, also can be the multi-turn cylindrical spring.
The convex shoulder of tube head 1 can be a platform convex shoulder shown in the accompanying drawing 1.Being provided with rubber pad 5 between tube head 1 and the fittings body 6, also can be the tubaeform convex shoulder shown in the accompanying drawing 2, and at this moment, tube head 1 and fittings body 6 are for the conical surface contacts, and an end face of metal gasket 4 is made the horn mouth shape.
In the present embodiment, spring 3 is to adopt the single-leaf spring pad.
Claims (5)
1, internal spring type SEALING FITTING is to be connected with fittings body 6 by nut 2, and inner nut 6 compresses tube head 1 and seals, and it is characterized in that being provided with spring 3 and metal gasket 4 in nut 2 and tube head 1 convex shoulder joint.
2, internal spring type SEALING FITTING according to claim 1 is characterized in that spring 3 can be the single-leaf spring pad, also can be the multi-turn cylindrical spring.
3, internal spring type SEALING FITTING according to claim 2, the convex shoulder that it is characterized in that tube head 1 is the platform convex shoulder.
4, internal spring type SEALING FITTING according to claim 2, the convex shoulder that it is characterized in that tube head 1 is tubaeform convex shoulder.
