Detailed Description

The features and principles of the present invention will be described in detail below with reference to the accompanying drawings, which illustrate embodiments of the utility model and are not intended to limit the scope of the utility model.

This heat supply network heater drain box, drain box include the drain box body, and the drain box is the hydrophobic integral type structure of storage that sets up in heat supply network heater bottom, and the drain box body comprises drain box barrel 1 and closure plate 2 at both ends, and drain box barrel 1 is installed in 5 bottoms on shell side barrel, and the below of drain box is equipped with drain opening 6. Because the blocking plate 2 is a flat plate, after the intensity calculation, the thickness of the blocking plate 2 is very thick. The utility model provides a brand-new drain box blocking plate 2 structure. Specifically, the blocking plate 2 is provided with a reinforcing member, and the reinforcing member at least comprises a reinforcing ring 3 and two reinforcing ribs arranged around the outer side of the reinforcing ring 3. Due to the adoption of the design form of the reinforcing ring 3 and the reinforcing ribs, the thickness of the blocking plate 2 is reduced to a great extent.

The blocking plate 2 is a flat plate and can be made of the same metal material as the material of the drain box cylinder 1. The central position welding of closure plate 2 has beaded finish 3, and beaded finish 3 is cylindric, and beaded finish 3 is the metal drum that has certain height promptly, and beaded finish 3 has certain height.

For the design form of strengthening rib, distribute the strengthening rib around 3 outer circles of beaded finish, the strengthening rib is around 3 even welding on closure plate 2 of beaded finish. Namely, the reinforcing ribs are distributed around the reinforcing ring 3 in a divergent manner around the reinforcing ring 3. The reinforcing ribs are made of the same material as the reinforcing ring 3.

The number of the reinforcing rings 3 can be more than one, that is, a plurality of reinforcing rings 3 can be arranged, each reinforcing ring 3 is concentrically arranged, and each reinforcing ring 3 has a cylindrical structure with different inner diameters and the same height. There is the space of interval between each strengthening ring 3, can set up the strengthening rib between each strengthening ring 3 or not set up the strengthening rib, if set up the strengthening rib between each strengthening ring 3, the strengthening rib between two strengthening rings 3 and the strengthening rib interval arrangement between two strengthening rings 3 in the outside.

For example, if three concentric reinforcement rings 3 are provided, the reinforcement rings 3 from inside to outside are defined as a first layer reinforcement ring 7, a second layer reinforcement ring 8 and a third layer reinforcement ring 9. Reinforcing ribs arranged between the first layer of reinforcing ring 7 and the second layer of reinforcing ring 8 are uniformly arranged around the first layer of reinforcing ring 7, and the reinforcing ribs at the positions are defined as a first ring of reinforcing ribs 10; reinforcing ribs arranged between the second layer of reinforcing ring 8 and the third layer of reinforcing ring 9 are uniformly arranged around the second layer of reinforcing ring 8, and the reinforcing ribs at the positions are defined as a second ring of reinforcing ribs 11; the first circle of reinforcing ribs 10 and the second circle of reinforcing ribs 11 are arranged on the blocking plate 2 at intervals.
