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 of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts 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 a heat preservation flange stop valve, including oral siphon 1, connecting pipe 2 and outlet pipe 3, the horizontal both sides of connecting pipe 2 communicate respectively has oral siphon 1 and outlet pipe 3, the top welding of connecting pipe 2 has ring flange 4, ring flange 4 is used for rotating the adjustment mechanism at top, and the inside central point of connecting pipe 2 puts the department and rotates and be connected with threaded rod 5, and threaded rod 5's top bolt fixedly connected with carousel 6, oral siphon 1 and outlet pipe 3's outside all wraps and is equipped with multiunit heat preservation ring 7, the outside package of connecting pipe 2 is equipped with heat preservation ring 7, heat preservation ring 7 independently moves each other, the inboard fixedly connected with magnet in top that is located the heat preservation ring 7 of connecting pipe 2 both sides.
Specifically, as shown in fig. 1 and 2, the bottom welding has two pivot 9 between oral siphon 1 and the outlet pipe 3, and all rotate on two pivot 9 and be connected with heat preservation ring 7, heat preservation ring 7 is two segmentation structures, and two sections tops have welded buckle 11 respectively and have rotated shifting block 12, and two sections heat preservation ring 7 inboards all are seted up fluted 8, the shape of recess 8 and oral siphon 1, the outer wall shape of outlet pipe 3 and connecting pipe 2 is identical, the horizontal mid point position department of shifting block 12 rotates and is connected with snap ring 13, and shifting block 12 passes through the joint between snap ring 13 and the buckle 11.
