The extruded natural gas pipeline joint of the utility model discloses a joint device which makes the pressure sleeve compact the pressure ring through the thread matching relationship, and then compacts and fixes the connecting hose and the connecting pipe through the matching of the pressure ring and the sealing ring. The joint device has simple structure, is convenient and practical, and can effectively improve the connection effect of the natural gas transmission pipe. The feature is that the thread sleeve is placed on the inner wall of the fixing sleeve. One end of the limiting sleeve is placed on one side of the thread sleeve, the outer wall of the limiting sleeve is provided with threads, the limiting ring is placed on the inner wall of the limiting sleeve, the rotating sleeve is placed on the limiting sleeve, and matched with the thread of the limiting sleeve, one end of the pressing sleeve is connected with the rotating sleeve, the diameter of the pressing sleeve is gradually reduced from one end to the other, one end of the connecting hose is placed in the pressing sleeve, and one end of the plurality of pulling pieces is respectively placed in the connecting soft part. The sealing ring is placed on the inner wall of the connecting hose, and the pressing ring sleeve is placed on the connecting hose. The diameter of the pressing ring gradually increases from one end to the other.

挤压式天然气管道接头
本技术挤压式天然气管道接头,涉及一种对天然气传输管进行连接的连接头装置,属于能源设备领域。特别涉及一种通过螺纹配合关系,使压套将压环压紧,再通过压环和密封环的配合对连通软管和连接管进行压紧固定的接头装置。
技术介绍
目前,天然气作为优质的燃料和化工原料,而被大量开采使用,天然气通常通过管道进行输送,橡胶软管作为常用的连接管道被大量使用,橡胶软管之间的连接通常通过连接管作为中介完成,进行连接时,通常先将橡胶软管套置在连接管上,为了防止橡胶软管从连接管上滑脱,传统的方式是在橡胶软管外侧绕缠铁丝等进行连接固定,采用该方式进行连接固定,容易使橡胶软管受力不均,长期使用容易使橡胶软管出现开裂等问题,使连接位置出现泄漏,使用效果不好。
技术实现思路
为了改善上述情况,本技术挤压式天然气管道接头提供了一种通过螺纹配合关系,使压套将压环压紧,再通过压环和密封环的配合对连通软管和连接管进行压紧固定的接头装置。能够有效提高对天然气传输管的连接效果。本技术挤压式天然气管道接头是这样实现的:本技术挤压式天然气管道接头由螺纹套、固定套、转动套、压套、压环、连通软管、密封环、拉片、限位套和限位环组成,螺纹套置于固定套内壁上,限位套一端置于螺纹套一侧,所述限位套外壁上置有螺纹,限位环置于限位套内壁上,转动套套置于限位套上,且和限位套螺纹配合,压套一端和转动套相连接,所述压套的直径从一端向另一端逐渐减小,连通软管一端置于压套内,多个拉片一端分别置于连通软管一端上,另一端分别和限位环相连接,所述密封环置于连通软管内壁上,压环套置于连通软管上,所述压环的直径从一端向另一端逐 ...
