Description

Bypass -type hot water thermostat {Bypass -type hot water thermostat}

The present invention relates to a hot water thermostat with a bypass function, and more particularly, to circulate the water hammer or the differential pressure in the pipeline when the flow is blocked by temperature control in circulating the hot water using the circulation pump to circulate the pump Apparatus for recovering to the boiler by opening the bypass pipe to protect the system, relates to an integrated bypass type hot water thermostat comprising a single body of temperature control and bypass functions.

In general, various types of thermostats and pressure control valves are used to control the flow and temperature of boiler heating or hot water, and these are all inconvenient to undergo separate bodies and separate control processes.

Therefore, technologies for the protection of the device itself, such as a dual-flow thermostat which reduces the influence of pressure and a thermostat that is not closed when closed, have appeared one after another, but when the pipeline is blocked by temperature control, the pressure affects the entire system. Due to the frequent damages and breakdowns of the facilities, the thermostat has caused distrust of the user, and is left without further progress.

The background technology of the present invention is a temperature-sensing temperature controller and a water temperature-sensing temperature controller, which will be described in more detail, there are electric and water-sensitized, electric is the ON / OFF opening and closing method of the solenoid by the temperature sensing , Anisotropic valve ON / OFF opening / closing method of motor drive by temperature sensing, ball valve opening / closing method of motor rotation by temperature sensing, etc., and water temperature-sensitive type is proportional control type using expansion of chemical property such as paraffin or mercury according to water temperature. There is a proportional control opening and closing method using the characteristics of the opening and closing method and SMA spring.

However, the above-mentioned electric type is formed of a disc type, a disc type, which is a cylindrical plate in a globe type port, and has a high failure rate due to the influence of pressure. In this method, the chemical properties change over time after the thermostat is installed, which causes it to harden or disappear.

Even in the case of using the characteristics of the SMA spring of the proportional control method described above, when using a disk made of a cylindrical plate, the force of the SMA spring does not withstand the pressure of the disk, so the opening and closing is not made smoothly, and even if the diarrhea is operated, sufficient pressure control is achieved. It is difficult to achieve normal temperature control.

1 is a comparative view comparing the influence of the pressure of a cylindrical disk disk and a double-flow disk.

As shown in FIG. 1, the disk having a cylindrical plate is difficult to close because the disk does not overcome the pressure in the case of 1-1, and the disk is difficult to open due to the pressure in the case of 1-2, In this case, the upper and lower parts are composed of one body of the same size, the lower disk is pushed upward and the upper disk is pushed downward, so the pressures on the disk cancel each other and move freely under any pressure change. The most ideal temperature control is possible.

2 is a cross-sectional view of the dual flow path port and the disk.

Among the temperature controllers, the most advanced method is a dual flow path temperature controller using the characteristics of the SMA spring, which is water-sensitized, and the dual flow path method is obtained by forming a port and a disk up and down as shown in FIG. After the hot water is divided into two places and passes through the port, it is gathered into one again. The upper and lower two disks are formed in one body and penetrate through the upper and lower cylindrical holes in the center. The pressures from top to bottom cancel each other out, allowing the disc to open and close without any problems with the weak force of the SMA spring.

However, the temperature control by the opening and closing operation alone cannot solve the differential pressure, which is a major cause of failure of equipment, circulation pump, and piping equipment.

The above thermostatic control and operation, when the temperature is low, the upper disk is closed, the lower disk is open, then gradually increases in temperature, the force increases in response to the temperature at which the SMA spring is recovered, the BIAS spring is relatively As it is compressed, the disk located in the middle of the two springs is moved upwards, opening the upper port and closing the lower port, blocking the return, stopping the intake and opening the bypass passage to bypass the incoming hot water to the heat supply.

The temperature control by the handle above, when turning the handle to the left and right, the key adjustment screw assembled by the control rod and the slide screw moves up and down, tightening or slowing down the BIAS spring, and the SMA spring is applied at a higher or lower temperature. To set and adjust the temperature.

In this way, stable temperature control by dual channel method, equipment protection and life extension, and relief of pressure difference, which is the most problematic in the device for supplying hot water using circulation pump, can protect the pipeline and facility and extend life.
