Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, the utility model provides a technical solution: a long alloy pipe sealing performance test fixture, including a base 17, a screw 8, a support ring 7, an upper pressure ring 5, a handle 4, an upper top Bolt 3, the two sets of screw rods 8 are installed on the two ends of the base seat 17 through two sets of T-shaped threaded nuts 9, the top of the screw rod 8 is passed through the third hexagon socket head cap screw 13, the second flat washer 15 and The second hex nut 14 is screwed and fixedly connected to the support ring 7. The bottom of the screw mandrel 8 is equipped with a round steel rotating handle 16, and the position of the supporting ring 7 is controlled by rotating the round steel rotating handle 16. One side is hinged with one end of the upper pressure ring 5 to realize the opening and closing movement of the upper pressure ring 5 relying on one end hinged with the support ring 7, and the other side of the support ring 7 passes through the pin hole on the fixed pin 6 and the upper pressure ring 5 Cooperate with each other, a symmetrical axis of the upper pressure ring 5 is screwed with a vertical upper bolt 3, and the upper bolt 3 is socketed with the handle 4, and the handle 4 is connected by the first hexagon socket head cap screw. 1 is fixedly connected with plug 2.

Specifically, the center of the top of the upper pressure ring 5 is provided with an internally threaded through hole matching the upper jack bolt 3 to realize the fastening of the upper jack bolt 3 to the test pipeline.
