Description

Technical Field

[0001] The utility model belongs to the technical field of ferrule accessories, in particular to a leakage-proof ferrule joint. Background Art

[0002] In the prior art, compression fittings compress the ferrule by interlocking threads, and the ferrule causes the tube to deform evenly to achieve a sealing effect. However, the currently commonly used compression fittings are prone to leakage due to vibration or thermal expansion and contraction after long-term use, and have poor sealing performance.

[0003] Therefore, it is urgent to develop a leak-proof ferrule joint with good sealing performance, simple structure and low manufacturing cost. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and specifically discloses a leak-proof ferrule joint, which has a simple structure, good sealing performance, better leak-proof effect, low production cost, can be used as a standard part for industry, and greatly improves the sealing performance.

[0005] In order to achieve the above technical objectives, the present invention is implemented according to the following technical solutions:

[0006] The utility model discloses a leak-proof ferrule joint, which comprises a joint body, a connecting pipe, a ferrule and a nut. The inner wall surface of the joint body is provided with a sealing ring groove for accommodating a sealing ring.

[0007] As a further improvement of the above technology, the sealing ring accommodated in the sealing ring groove is a O-shaped sealing ring.

[0008] As a further improvement of the above technology, the rear end portion of the joint body is an inner cone surface, and the outer circumferential surface of the ferrule is also a cone surface, and the cone angles of the two are consistent in size and direction.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] (1) The leak-proof ferrule joint of the present invention has a sealing ring groove and an O-shaped sealing ring on the inner wall of the joint body, thereby improving the soft sealing performance between the connecting pipe and the joint body, and a hard seal formed by the rigid fastening connection between the nut, the ferrule and the ferrule joint, which greatly improves the sealing performance of the ferrule joint, has a good anti-leakage effect, and can be widely used in any place where a ferrule joint is required;

[0011] (2) The leak-proof ferrule joint described in the present invention retains the structure of the existing ferrule joint and is an improvement on the original structure. It is simple to manufacture and has a low manufacturing cost. It can be used as a standard part in the industry, greatly reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments:

[0013] Figure 1 It is a schematic structural diagram of a leak-proof ferrule joint of the utility model. DETAILED DESCRIPTION

[0014] like Figure 1 As shown, the leak-proof ferrule 3 connector described in the present invention includes a connector body 1, a connecting pipe 2, a ferrule 3 and a nut 4. The inner wall surface of the connector body 1 is provided with a sealing ring groove for accommodating a sealing ring.

[0015] In the present invention, the sealing ring accommodated in the sealing ring groove 11 is a O-shaped sealing ring 5, which improves the sealing performance.

[0016] In addition, in order to improve the fit between the connector body 1 and the ferrule 3, the rear end of the connector body 1 is an inner cone-shaped conical surface, and the outer circumferential surface of the ferrule 3 is also a conical surface, and the cone angles of the two are consistent in size and direction.

[0017] The present invention is not limited to the above-mentioned embodiments. Any changes or modifications to the present invention that do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
