Temperature control valve for automatically switching flow direction according to water temperature

Abstract

The invention relates to a temperature control valve for automatically switching a flow direction according to a water temperature and belongs to the field of manufacturing of water heating equipment. The temperature control valve is characterized in that: a water flow outlet is formed in a valve cover; a water flow inlet is formed below the water flow outlet; the water flow outlet is communicated with a water outlet B; the water flow inlet is communicated with a water inlet A; and a through hole at the lower end of the valve cover is communicated with a water outlet C. By the temperature control valve, a higher-temperature thermal medium flowing out of radiating equipment is conveyed back to the radiating equipment, the aim of repeated heat utilization is fulfilled, and backwater at a low temperature is directly conveyed back to a boiler room; and when the device automatically switches the flow direction, external power is not needed.

Description

technical field [0001] The invention relates to a temperature control valve for automatically switching the flow direction according to the water temperature, which belongs to the field of plumbing equipment manufacturing. Background technique [0002] The existing winter heating, due to the adoption of more advanced technologies such as installing heat meters, effectively controls the indoor temperature and reduces the waste of heat energy a lot. However, due to historical reasons, the existing heating system still has some defects; for example, the return water temperature of the heat medium is sometimes very high, and the heat energy is not fully utilized, so it is sent back to the boiler room by the return water pipe; The hot water to the user, although the temperature does not vary greatly, still passes through the heat meter. This defect is unfair to the user on the one hand, and on the other hand, the heat energy is not fully utilized, resulting in a waste of heat ene...

However, due to historical reasons, the existing heating system still has some defects; for example, the return water temperature of the heat medium is sometimes very high, and the heat energy is not fully utilized, so it is sent back to the boiler room by the return water pipe; The hot water to the user, although the temperature does not vary greatly, still passes through the heat meter. This defect is unfair to the user on the one hand, and on the other hand, the heat energy is not fully utilized, resulting in a waste of heat energy in essence.
