Abstract
本实用新型涉及一种丝扣连接件，具体涉及一种防漏水丝扣连接件。其包括连接件主体，还包括密封圈和螺帽，密封圈设置在连接件主体的一端，螺帽与连接件主体一端连接并对密封圈压紧定位；密封圈上厚下薄，连接件主体一端内壁设置与密封圈相贴合的倒角。本实用新型通过拧紧螺帽对密封圈施加轴向力，迫使密封圈向下运动，同时连接件主体一端内壁开有的倒角与上厚下薄的密封圈外形贴合后，对密封圈施加一个径向力，迫使其在径向方向上锁紧插入的管材从而到达密封效果。根据同一规格不同材质管材外径的变化，通过调节螺帽的拧入深度即可控制所需的密封性程度，有效解决同一规格不同管材外径变化造成的密封性不稳定的缺陷。
The utility model relates to a threaded connector, in particular to a leak-proof threaded connector. It includes the main body of the connecting piece, and also includes a sealing ring and a nut. The sealing ring is arranged at one end of the main body of the connecting piece. The nut is connected to one end of the main body of the connecting piece and presses and positions the sealing ring; The inner wall at one end is provided with a chamfer that fits the sealing ring. The utility model exerts an axial force on the sealing ring by tightening the nut, forcing the sealing ring to move downward, and at the same time, after the chamfer on the inner wall of one end of the main body of the connector fits the shape of the sealing ring with a thick top and a thin bottom, the sealing ring is applied A radial force forces it to lock the inserted pipe in the radial direction to achieve a sealing effect. According to the change of the outer diameter of pipes of different materials of the same specification, the degree of sealing required can be controlled by adjusting the screwing depth of the nut, which effectively solves the defect of unstable sealing caused by the change of outer diameters of pipes of the same specification and different materials.
Description
Technical field
The utility model relates to a kind of screwed connection part, is specifically related to a kind of preventing water leakage screwed connection part.
Background technique
Existing screwed connection part is realized sealing effect by the tubing that the single radial force of extruding rubbery flat gasket circle generation makes the rubbery flat gasket circle be adjacent to connection usually.Because the rubbery flat gasket circle is to design after determining according to the size of tubing, so can reach the sealing effect of expection.In case but when the external diameter of tubing changed, the size of rubbery flat gasket circle just can not be complementary with tubing, causes the joint easily to leak, adaptability is lower.
The model utility content
The technical problem that the utility model solves is to overcome the deficiencies in the prior art, provides a kind of and can adapt to the preventing water leakage screwed connection part that the unlike material tube outer diameter changes and can reach sealing effect
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of preventing water leakage screwed connection part comprises connector main body, also comprises seal ring and nut, and seal ring is arranged on an end of connector main body, and nut is connected with connector main body one end and seal ring is compressed the location.
In the such scheme, described seal ring is upper thick and lower thin, the chamfering that connector main body one end inwall setting and seal ring fit.
In the such scheme, be provided with the outside thread that is connected with nut on the described connector main body one end outer wall.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
The utility model applies axial force by tightening nuts to seal ring, force seal ring to move downward, after the chamfering that while connector main body one end inwall has and upper thick and lower thin seal ring profile are fitted, seal ring is applied a radial force, thereby force its tubing in the radial direction locking insertion to arrive sealing effect.According to the variation of same specification unlike material tube outer diameter, by being screwed into the degree of depth and can controlling required sealing degree of regulating nut, effectively solve the different tube outer diameter of same specification and change the unsettled defective of sealing that causes.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model connector main body;
Fig. 3 is the structural representation of the utility model seal ring.
Embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is described further.
As shown in Figure 1 to Figure 3, a kind of preventing water leakage screwed connection part comprises connector main body 1, nut 2 and seal ring 3; Seal ring 3 is upper thick and lower thin, it is arranged on an end of connector main body 1, the chamfering 11 that connector main body 1 one end inwall settings and seal ring 3 fit, chamfering 11 shapes and seal ring 3 be upper thick and lower thin be set to accordingly up big and down small, be provided with outside thread 12 on the connector main body 1 one end outer walls, nut 2 is connected with the outside thread 12 of connector main body 1 one ends and seal ring 3 is compressed the location.
