Abstract

The utility model provides a double ring sealing combined joint, relates to a pipe joint, in particular to a combined joint which can achieve double ring sealing. The double ring sealing combined joint comprises a connector (1) and a plug (2), wherein the connector (1) and the plug (2) are connected in a mutual inserting mode. The double ring sealing combined joint is characterized in that a chamfer (4) is arranged on an inner wall of an end head of the connector (1), a sealing ring groove is arranged on the plug (2) close to an end head of the plug (2) in circumferential mode. An annular sealing ring (3) is embedded in the sealing ring groove. A spherical boss (5) with a smooth surface is arranged on a contact portion of the plug (2) and the chamfer (4) of the connector (1). The double ring sealing combined joint has the advantages of double sealing, high safety factor and effective prevention of gas or liquid leakage.

Description

Dual annular seal combination joint
Technical field
Dual annular seal combination joint relates to a kind of pipe joint, is specifically related to a kind of built-up joint that can realize dual ring packing.
Background technique
Present pipe joint linkage structure all is one sealing mostly; Plug inserts in the joint; And make the awl circle on plug and the joint produce sealing state under the effect of union nut; But this sealing configuration still has deficiency, mainly shows when plug sphere and joint awl circle is gone up arbitrary sealing surface and damaged to some extent gas or the external seepage of liquid in all can causing managing.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, a kind of double seal that has is provided, safety coefficient is higher, can effectively prevent the built-up joint of gas or fluid seepage.
The utility model solves the technological scheme that its technical problem adopted: this dual annular seal combination joint; Comprise the joint and the plug that are plugged on each other together; It is characterized in that: joint termination inwall is provided with chamfering; Plug has o-ring groove near the end circumference, and o-ring groove is embedded in O-ring seal, and the contact position of the chamfering of plug and joint is provided with the slick and sly sphere boss in surface.O-ring seal on the plug and sphere boss can form two seals, realize the double seal protection of pipe joint, improve safety coefficient.
Described joint and plug compress through union nut after pegging graft, and can prevent that pipeline is loosening, slippage.
Compared with prior art, the beneficial effect that had of the dual annular seal combination joint of the utility model is:
1, realizes the double seal protection of pipe joint; Improve safety coefficient: O-ring seal on the plug and sphere boss can form two seals; After if O-ring seal damages, the sphere boss on the plug and the chamfering of joint realize the sealing of second road, the seepage of gas or liquid in preventing to manage; Realize the double seal protection of pipe joint, improve safety coefficient;
2, simple in structure, economic and practical: utilize O-ring seal and sphere boss to realize the double seal protection, simple in structure, make easily, economic and practical.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Wherein: 1, joint 2, plug 3, O-ring seal 4, chamfering 5, sphere boss 6, union nut.
Fig. 1~2nd, the most preferred embodiment of the dual annular seal combination joint of the utility model further specifies below in conjunction with 1~2 pair of the utility model of accompanying drawing:
Embodiment
With reference to accompanying drawing 1~2: this dual annular seal combination joint, comprise the joint 1 and plug 2 that are plugged on each other together, joint 1 and plug 2 back of pegging graft compresses through union nut 6.Joint 1 termination inwall is provided with chamfering 4, and plug 2 has o-ring groove near the end circumference, and o-ring groove is embedded in O-ring seal 3, and plug 2 is provided with the slick and sly sphere boss 5 in surface with the contact position of the chamfering 4 of joint 1.
As shown in Figure 2; O-ring seal 3 on the plug 2 can form two seals with sphere boss 5; The double seal protection of realization pipe joint, after O-ring seal 3 damaged, gas or liquid can be sealed in the chamfering 4 and the sphere boss 5 formed cavitys on the plug 2 of joint 1 in the pipe; Prevent seepage, improved safety coefficient.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technological scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technological scheme according to the technical spirit of the utility model.
