BG112675A - Inlet water heater nozzle - Google Patents

Abstract

The inlet nozzle for water heater finds application in incorporation in water heaters of horizontal and vertical type and also both for those mounted on the floor and for those that are mounted on a wall. It ensures even mixing of the two layers of water - hot and cold, which saves energy and prevents rapid cooling of the already heated water. The inlet nozzle for water heater includes an outer housing (1) in which an inner tube (4) is located. It is connected to the supply pipe (3). To the upper end of the outer housing (1) is coupled connecting tip (2). To the lower end of the inner tube (4) is connected a water nozzle (5) with an extended upper end. The lower end of the inner tube (4) is closed. On the water nozzle (5) laterally are made discharge openings (6). The upper part of the outer housing (1) is shaped like a hemisphere (7). To its lower end is attached a middle cylindrical section (8). To it is attached a cone-shaped section (9), the wider end of which is oriented towards the inner wall (10) of the water heater (11). The lower end (12) of the water nozzle (5) is extended beyond the lower plane (13) of the cone-shaped section (9). To the lower end (12) of the water nozzle (5) is attached a locking tip (15) with a rounded configuration. This locking tip (15) is propped on the inner wall (10) of the water heater(11).

Description

INPUT BOILER NOZZLE

Field of technology

The invention relates to an inlet nozzle for a boiler, which is used in hot water boilers and in particular for those horizontal or vertical type, which are located on the floor, as well as for all types of wall-mounted boilers.

BACKGROUND OF THE INVENTION

A water inlet pipe for a boiler is known, which is described in / 1 /. It consists of an outer housing with a water inlet connector with an inner water supply pipe. An internal threaded hole is formed in the upper end of the outer housing. An outlet is formed at the upper end of the inner tube. Exhaust vents are made on the side of the inner tube. On the inner tube is mounted an outer tube, on which the same laterally drilled holes are located above each of them fixed inclined plates. A water flow reflector is placed at the upper end of the inner tube.

A disadvantage of the design thus described is that the mixing process between hot and cold water cannot be effectively controlled during the use of the boiler. Another disadvantage is that the rapid cooling of already heated water cannot be prevented, which leads to significant energy consumption, especially in horizontal or vertical type boilers, as well as in those that are located on the floor, as well as wall-mounted.

Technical essence of the invention

The object of the invention is to provide an inlet nozzle for a boiler, which effectively controls the process of mixing hot and cold water during the use of the boiler, preventing rapid cooling of the already heated water and achieving energy savings in horizontal to vertical water heaters located on the floor, as well as wall-mounted.

The problem is solved by an inlet nozzle for the boiler, which includes an outer housing in which is located an inner tube, which is connected to the supply pipe. According to the invention, a connecting end is attached to the upper end of the outer housing. A water jet is connected to the lower end of the inner tube. The lower end of the inner tube is open.

Drain holes are formed on the side of the water jet.

The upper part of the outer hull is shaped like a hemisphere, to the lower end of which a middle cylindrical section is attached.

A cone-shaped section is attached to the lower end of the middle cylindrical section, the wider end of which is oriented towards the inner wall of the boiler.

The lower end of the water jet is extended beyond the lower plane of the conical section. A locking nozzle with a rounded configuration is attached to the lower end of the water jet. The fixing nozzle rests on the inner wall of the boiler.

Longitudinally reinforcing ribs are formed on the water jet.

An advantage of the invention is that the mixing of hot and cold water can be precisely controlled during the operation of the boiler. Another advantage is that it prevents the rapid cooling of the already heated water by achieving energy savings both for floor-standing and wall-mounted boilers.

An embodiment of the invention

The inlet nozzle for the boiler includes an outer housing 1 in which an inner tube 4 is located. It is connected to a supply pipe 3. A connecting nozzle 2 is attached to the upper end of the outer housing 1. A water jet 5 is connected to the lower end of the inner tube 4. with extended upper end. The lower end of the inner tube 4 is open. Exhaust openings 6 are formed laterally on the water jet (5). The upper part of the outer housing 1 is formed as a hemisphere 7, to the lower end of which a middle cylindrical section 8 is connected. To it is attached a conical section 9, the wider end of which is oriented to the inner wall 10 of the boiler 11. The lower end 12 of the water jet 5 is extended beyond the lower plane 13 of the conical portion 9. To the lower end 12 of the water jet 5 is attached a fixing nozzle 15 with a rounded configuration. This fixing nozzle 15 is supported in the inner wall 10 of the boiler 11. Longitudinally reinforcing ribs 14 are formed on the water jet 5.

Use of the invention

When water enters the boiler 11, thanks to the water jet 5 the direction and speed of the cold water is directed, ensuring its calm and even distribution. Due to the shape of the outer housing 1, the separation of the two layers - hot and cold water on the bottom of the boiler 11 is guaranteed. Due to the fact that the lower end 12 of the water jet 5 is outside the lower plane 13 of the conical section 9, it can be optimally provided. distance between the inner wall 10 of the boiler 11 and the lower plate 13 of the conical section 9, which ensures an economical mode of mixing hot and cold water. The locking nozzle 15 with a rounded configuration does not allow damage to the inner coating of the boiler during transport and installation.
