The internal screw thread to match is arranged in sleeve gasket inner wall, rubber sleeve gasket and bolt outer wall can be made more to be bonded, gap between the two is more
It is small, then interference above-mentioned is cooperated to be arranged, so that sealing performance further increases.
The lower surface of the round doily of the rubber sleeve gasket is equipped with seal groove, and seal groove is arranged, and pushes rubber in gland nut
It can produce bigger deformation when sleeve gasket, so that the seal degree between rubber sleeve gasket and mill tube wall is more preferable.
The upper portion side wall of the gland nut is equipped with a hole for injecting glue, the outlet of the hole for injecting glue be located at the top of rubber sleeve gasket and
The intersection of bolt.The abrasion of rubber sleeve gasket, the utility model after being vibrated for a long time with the aging of rubber sleeve gasket or rod mill
Raw rubber can be vulcanized to injection delay between rubber sleeve gasket and bolt by setting hole for injecting glue, filled up caused by being shunk because of rubber sleeve gasket
Gap, to extend the service life of entire sealing device.
The inner wall of the hole for injecting glue is equipped with internal screw thread, and passes through screw closure.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) structure is simple, easy for installation；
(2) by the design such as lozenges, internal screw thread, interference fit, so that the sealing device has good sealing effect；
(3) by setting hole for injecting glue, the service life of sealing device can effectively be extended with individual treatment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 is bolt, and 2 be locking nut, and 3 be gland nut, and 4 be rubber sleeve gasket, and 5 be mill tube wall, and 6 be liner plate, 7
It is seal groove for frotton, 8,9 be hole for injecting glue, and 10 be screw.
Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
