In this proposal, the indoor temperature can be set to the user's desired temperature in a hot water heating device such as a house, apartment, or office that is equipped with boiler for district heating or central heating. The heating water control valve, which opens and closes according to the room temperature change of each room and supplies or cuts off the heating water, is installed as an independent object for each heating water supply pipe of each room, so Consists of a normal temperature sensing unit for sensing the temperature of the room having a charged radiator, and an operation unit for driving the operation pin back and forth by the expansion and contraction action of the bellows connected to the radiator of the temperature sensing unit. It automatically supplies or cuts off the heating water, Room temperature in the water heating device that can by maintained constant relates to the automatic control unit.

Conventionally, in the hot water heating device, various control devices have been devised to keep the room temperature constant in a desired state. For example, the temperature control method in which the hot water pipe is embedded is operated when the water temperature reaches a certain temperature. This is to be stopped, by the one temperature sensor installed in the room was to stop or turn off the boiler by shutting off the power when the air temperature in the room reaches a certain temperature.

These devices differ in the temperature of the heating water flowing through each part of the hot water pipe, and manually controls the distribution of the heating water by manually manipulating the hot water control valve installed in each room for heating, but this controls the flow rate of the heating water to some extent. Even if it is possible, there were inconveniences such as the need for artificial valve operation every minute to maintain the room temperature and the temperature change of the heating water, which changes according to the operating time of the boiler.

In order to solve the above inconveniences, flanges are formed on both sides of the hot water valve formed at the lower part of the pipe connector to connect the hot water pipes so that the hot water valve and the end cap can be connected. Hot-water dispenser combined temperature control valve device (utility model registration application No. 90-20612) by integrally installing a temperature control device composed of an expansion barrel repeating expansion and contraction, and a slide shaft supported by a spring and a disk for opening and closing a pipe connector. ) Has been proposed.

Therefore, it is equipped with a thermostat consisting of a slide shaft and a pipe for opening and closing the pipe connector connected to the expansion tube and a spring in one hot water valve, respectively, is installed in the connection of the hot water pipe, which can automatically adjust the room temperature of each room without manual operation. Although there is an advantage, in practice, a plurality of hot water pipes arranged in each room of the room are collected in one hot water valve to distribute hot water, and the disk of the thermostat is connected to each connector of a plurality of hot water pipes formed in the hot water valve. Each connector is opened and closed. At this time, a temperature control device having several disks is installed at one time in a single hot water valve, so that when the hot water introduced into the hot water valve is supplied to the connector of each hot water pipe, the flow rate and hydraulic pressure of the hot water are increased. Including flow velocity and temperature of hot water Each thermostat has a drawback that it is impossible to maintain and maintain the correct set temperature even if the desired temperature is set to affect each other's connecting ports. Therefore, the hot water pipe has a disc for opening and closing the hot water pipe. By installing a plurality of temperature controllers, the hot water valve was merely a distributor for supplying hot water to the hot water pipes, but there was a structural problem in that the temperature of the hot water supplied to each hot water pipe could not be accurately controlled and controlled.

In addition, due to the complicated structure of several temperature regulating devices in a single hot water valve, frequent defects occur, and product life is shortened, and there are also difficult problems in manufacturing.

Therefore, in recent years, it is possible to prevent failure cases due to the complicated structure as described above, and to install a separate hot water control valve for each room without using a temperature control valve that serves as a single separator to control the temperature of each room. It is a situation that a heating water control valve that can maintain the correct set temperature is desired.

In order to solve the above-mentioned problems and to meet the requirements, this paper proposes a simple structure of the heating water control valve for supplying and shutting off the heating water in the hot water heating system, and the replacement and installation work is simple. In addition, the bellows of the operating part can be expanded and contracted precisely according to the amount of expansion of the radiator's vermiculum in response to the change in the room temperature detected by the temperature sensing unit, so that the heating water control valve can be opened and closed quickly and accurately. By installing these control valves as independent objects for each heating water supply pipe, it provides an automatic control of the indoor temperature in the hot water heating system that can automatically control and operate the supply of heating water to maintain the set indoor temperature. There is a purpose of devising.
