The invention relates to the technical field of petroleum pipe fittings, in particular to a protective nonmetal petroleum pipe fitting which comprises two pipe bodies, a wear-resisting mechanism and a hoisting mechanism, the wear-resisting mechanism and the hoisting mechanism are mounted on the two pipe bodies, a sealing mechanism is arranged between the two pipe bodies, and fixing mechanisms are arranged at the opposite ends of the two pipe bodies; the hoisting equipment is matched with the two hoisting mechanisms to draw close the two pipe bodies, the two pipe bodies are connected in a hot melting connection mode, when the opposite ends of the two pipe bodies abut against each other, the inserting rods on the side wall of the fixing ring on one pipe body can be inserted into the inserting holes in the other pipe body, the multiple inserting rods further extrude the limiting rods in the radial direction at the same time, and therefore the limiting rods can be fixed. The springs are opened, the limiting rods penetrate through the interiors of the pipe bodies, the limiting rods are buckled with the limiting holes in the outer walls of the connecting pipes, the stability of connection between the two pipe bodies is improved, breakage of the connecting positions of the pipe bodies is avoided, the thickness of the containing grooves in the ends of the pipe bodies can be compensated through the connecting pipes, and the pressure resisting effect of the pipe bodies is improved.
本发明涉及石油管件技术领域,具体的说是一种防护型非金属石油管件,包括两个管体、安装于两个管体上的耐磨机构、吊装机构,两个所述管体之间设有密封机构,两个管体的相对端设有固定机构;通过吊装设备配合两个吊装机构将两个管体靠拢,通过热熔连接方式将两个管体连接,在两个管体的相对端抵触的时候,其中一个管体上的固定圈侧壁的插杆会插入另一个管体上的插孔内部,进一步的多个插杆同时将限位杆径向挤压,弹簧张开,限位杆贯穿管体的内部,且限位杆与连接管外壁的限位孔扣合,增加了两个管体之间连接的稳定性,避免管体连接处发生断裂,且连接管的设置可以对管体端部安置槽处的厚度得到补偿,提高管体的耐压效果。
