Description

Suction-proof water-operated temperature control valve

Technical Field

The patent relates to a prevent sucking hydrodynamic temperature control valve, especially relate to a take temperature control device's hydrodynamic force to block negative pressure suction channel's valve mechanism.

Background

With the continuous improvement of social material conditions, people are increasingly in need of improving daily life appliances to improve convenience and comfort. Zero-down cold water is becoming an important field of appliance improvement. In the household, when people want to use the cold and hot water, people always need to discard a lot of cold water to flow out the hot water, so that precious fresh water resources are wasted, and a long time is needed. The zero cold water is heated by circulating the cold water cooled and retained in the hot water pipeline through a special valve mechanism and flowing the cold water from the cold water pipeline back to the water heater. In reality, two kinds of valve mechanisms for solving the problem are mainly used, namely, a one-way valve (commonly called a check valve) is simply used for bridging, namely, a cold water pipe and a hot water pipe are simply communicated, so that hot water can enter the cold water pipe without being throttled when people simply use cold water, and according to Bernoulli principle, people know that the flowing liquid pressure is smaller than that of static liquid, and the reason that the cold water pipe sucks the hot water is that. The hot water enters the cold water pipeline firstly to waste heat energy, and secondly, the wall thickness of the cold water pipeline is smaller than that of the hot water pipeline, so that the service life of the pipeline can be reduced after the hot water enters the pipeline for a long time, and the potential risk of pipe explosion exists. Thirdly, hot water enters facilities such as a toilet bowl, a squatting pan and the like, and peculiar smell can be spread. Fourthly, families using the gas water heater can cause the false start of the gas water heater due to the suction, so that the gas is wasted and unnecessarily puzzled. This patent utilizes hydrodynamic force to let the sliding piston block hot water channel, makes people do not have hot water to intervene when using cold water, has protected cold water pipeline, has avoided heat energy loss, has stopped the peculiar smell production, has more got rid of the mistake of gas heater and has started, can more the zero cold water system of construction family.
