Description

[Detailed Description of the Invention] This invention relates to a boiler device consisting of a boiler body and accessory parts such as a circulation pump, a safety valve, and a closed expansion tank.

Conventionally, in closed heating boiler equipment, accessory equipment such as a circulation pump, safety valve, automatic air vent valve, and closed expansion tank are separate from the boiler itself, making handling difficult and complicated facility construction. Requires a large facility area.

With the above points in mind, this idea was developed by attaching accessories such as a circulation pump to one side wall of the boiler body, making the device more compact and lower in price, reducing equipment time, and reducing assembly and installation costs. The purpose of this invention is to facilitate pipe connection work and improve the appearance. Next, this invention will be explained in detail with reference to a drawing showing one embodiment of the invention.

As shown in the drawing, a hot water circulation pump 2, a safety valve 4 via an elbow 3, a sealed expansion tank 5, a supply/drain valve 6, and a plurality of sockets 7 are installed on one side wall of the boiler main body 1. Hot water return headers 8 each having a piping port are directly attached, an automatic air vent valve 10 is provided on the upper part of the casing 9 of the hot water circulation pump 2 to remove air from the piping, and a hot water return header 11 is provided on the lower part of the casing 9. The lower part of the casing 9 and the socket 7 are connected through a half union 12 and a connecting pipe 13 made of copper pipe, and a bypass is provided between the circulation pump 2 and the hot water header 11.

Furthermore, hot water return header 8 and hot water outgoing header 1
1 is positioned at an intermediate height of the side wall, and the circulation pump 2, safety valve 4, expansion tank 5, etc. are surrounded by a cover 14 attached to the boiler body 1 and having an opening at the bottom for taking out the piping, thereby achieving waterproofing.

In addition, small bore steel pipes of 8.00 mmφ, 9.52 mmφ, etc. are used for the piping.

15 is a chimney of the boiler body 1, and 16 is a single-sided hose nipple attached to the supply/drain valve 6.

Therefore, when performing heating with the apparatus of the embodiment, the installation work is completed by simply connecting both the hot water sending and returning headers 11 and 8 to the radiator.

Water is supplied to the boiler body 1 by connecting a hose to the nipple 16 attached to the supply/drain valve 6. After water supply is completed, close the supply/drain valve 6 and remove the hose from the nipple 16. If the hose is out of the way.

In addition, in the boiler device with the specifications shown in Table 1, which was manufactured based on the example, heating of three rooms could be kept at an extremely low price including construction costs.

As described above, according to the boiler device of this invention, a circulation pump, a safety valve, a closed expansion tank, a supply/drainage valve, and a hot water return header having multiple piping ports are mounted on one side wall of the boiler body. an automatic air vent valve is provided in the upper part of the casing of the circulation pump, a hot water outgoing header having a plurality of piping ports is provided in the lower part of the casing C, and the lower part of the casing and the hot water return header are connected for bypass. The hot water return header and the outgoing header are connected by a pipe, and the hot water return header and the outgoing header are located at an intermediate height of the side wall, and further, each accessory attached to the side wall is attached to the boiler body, and the lower part is used for pipe extraction. By covering the boiler with an open cover, the entire equipment can be made more compact and lower in price. At the same time, the circulation pump and other accessories are integrated into the boiler, reducing installation time. Furthermore, since the accessory parts are grouped together on one side wall of the boiler body, assembly is easy, and since both headers are located at the middle height of the side wall, piping connection work is not difficult. It is easy to install without having to change the posture or topple the casing, and since each accessory is covered with a cover with an opening at the bottom, the piping can be pulled out downward along the boiler body from the opening at the bottom of the cover. At the same time, the appearance is improved.
