Self-control two-way direct-current low-voltage electric temperature control valve

Abstract

The invention relates to a self-control two-way direct-current low-voltage electric temperature control valve, and belongs to the technical field of water heating valves. The valve is characterized in that: a main valve and a branch valve are pilot valves; a piston on a valve core controls the closing of a pressure relief opening; a main water outlet in the valve is opened or closed by the piston through a water pressure difference; the water inlet of the branch valve is connected with a valve body; the water outlet of the branch valve can be connected with the water outlet of the main valve, and also can form an independent system; and control boxes are control mechanisms which are arranged above the main valve and the branch valve and work according to programs.

Description

technical field [0001] The utility model relates to a self-controlled dual-channel direct-current low-voltage electric temperature control valve, which belongs to the technical field of heating valve control. Background technique [0002] In recent years, with the advancement of valve technology, various electric valves have also begun to be applied in the field of winter heating; such as solenoid valves, electric valves driven by motors, and electrothermal temperature control valves; but the defects of the existing technology are: 1. It is not safe to use 220V AC power supply; 2. It does not have antifreeze function: when the ambient temperature is close to or lower than 0°C after the valve is closed, the radiator and heating pipes will be damaged by freezing, and in severe cases, people in the room will be frostbitten. Incidents of broken equipment and frostbite personnel occur almost every year. Another phenomenon is that when people are active during the day, the heatin...

[0002] In recent years, with the advancement of valve technology, various electric valves have also begun to be applied in the field of winter heating; such as solenoid valves, electric valves driven by motors, and electrothermal temperature control valves; but the defects of the existing technology are: 1. It is not safe to use 220V AC power supply; 2. It does not have antifreeze function: when the ambient temperature is close to or lower than 0°C after the valve is closed, the radiator and heating pipes will be damaged by freezing, and in severe cases, people in the room will be frostbitten. Incidents of broken equipment and frostbite occur almost every year

Another phenomenon is that when people are active during the day, the heating is normal. After get off work, although many units are empty, the heating is still carried out at the normal temperature, resulting in a large amount of waste of heat energy.
