Description

An automatic valve for the automatic supply system of a hot water boiler}

The present invention relates to an automatic valve for a boiler hot water automatic supply system, and more specifically, to prevent water hammer phenomenon in an automatic valve that can be applied to a hot water automatic supply system for a boiler to selectively heat only a specific room to be heated. And it is to provide an automatic valve (also called a 'direct acting automatic valve') that can be manually opened and closed.

In general, in heating systems using various boilers (including centralized heating and district heating, houses using single boilers, etc.), the temperature controller for each household is used to control the temperature of the whole hot water heated by the boiler.

In the case of the heating system through the hot water control for the existing boiler, even if one household or one room is heated, the whole heating is performed, so the hot water is continuously circulated to the boiler, which wastes unnecessary energy and requires heating. The development of a new automatic hot water supply system for boilers is urgently needed because it has a very unreasonable structure such as not being able to perform heating immediately.

In order to solve this problem, the inventors of the present invention install automatic valves (application number: 10-2000-0029128) on the outlet pipe branched on the distributor for the boiler so that only the room requiring heating can be individually controlled. Solving the problems of the conventional heating system for the boiler by having a controller that can be controlled individually.

However, the automatic valve proposed in the above-described prior invention is to control the hot water supply while opening and closing a through-hole through which hot water on the diaphragm can pass while the electromagnet operates by lifting and lowering the valve plunger according to whether power is applied.

This is because the valve plunger moves up and down rapidly according to the power supply, so pipe noise and vibration caused by the water hammer are needed.

In the past, an air chamber was sometimes used to protect precision equipment related to piping from shock waves caused by water hammer, which is maintained in the chamber during initial installation. Absorption of water occurs, the function of absorbing shock waves is reduced, and after a certain period of time there is a disadvantage that the function is lost.

Therefore, in the present invention, in the automatic valve installed on the outlet pipe branched on the boiler distributor to selectively heat only a specific room to selectively heat the water, the water hammer generated during the opening and closing operation of the automatic valve is provided. The present invention has been completed in view of the technical problem of the present invention to provide an automatic valve for a hot water automatic supply system for a boiler having a means for minimizing damage to the device due to the phenomenon and minimizing noise and vibration.
