Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution:
the utility model provides an utilize sealed sleeve compensator of automatic pressurization of pipeline expend with heat and contract with cold, including compensator inner skleeve 2 and compensator outer sleeve 3, compensator outer sleeve 3 has been cup jointed in the one end outside of compensator inner skleeve 2, the left side of the one end fixedly connected with of compensator outer sleeve 3 seals filler support ring 5, the inboard fixedly connected with right side of compensator outer sleeve 3 seals filler support ring 11, be equipped with flexible sealing filler 8 between left side seal filler support ring 5 and the right side seal filler support ring 11, the even intercommunication in the outside of compensator outer sleeve 3 has flexible filler injection nozzle 4, the utility model relates to a sleeve compensator of brand-new structure, the maintenance need not be followed in the installation, can seal automatically, and it generally installs in the great department of thermal power pipeline expend with heat and contract with cold stress, can eliminate the stress that thermal power pipeline expend with heat and contract with cold.
Compensator inner skleeve 2's one end outside fixedly connected with pipeline inflation spacing ring 1, compensator inner skleeve 2's the other end outside fixedly connected with pipeline shrink spacing ring 9, better spacing effect can be played in this kind of setting, prevent the slip of its transition, left side gland packing support ring 5's right side is equipped with left gland packing ring 6, and right gland packing support ring 11's left side is equipped with right gland packing ring 10, better sealed effect can effectively be guaranteed in this kind of setting, compensator inner skleeve 2's outside fixedly connected with flexiplacking thrust ring 7, and flexiplacking thrust ring 7 is located between left gland packing ring 6 and the right gland packing ring 10, this kind of setting can be when not taking place the harmomegathus, guarantee better stability.
