Temperature sensing reversing valve

Abstract

The invention discloses a temperature sensing reversing valve, which belongs to the technical field of valves. The reversing valve comprises a valve body, a temperature sensing reversing valve element, a temperature sensing switching component and a valve body blanking cover component; the valve body is provided with a medium inlet passage, a low temperature medium outlet passage and a high temperature medium outlet passage; certain ends of the medium inlet passage, the low temperature medium outlet passage and the high temperature medium outlet passage are communicated in the valve body; the temperature sensing reversing valve element is in the communicating position of the three passages in the valve body; the temperature sensing switching component is disposed on one end of the temperature sensing reversing valve element higher than the high temperature medium outlet passage; the valve body blanking cover component is arranged on one end of the valve body higher than the high temperature medium outlet passage. The invention further provides another temperature sensing reversing valve. The invention can realize a temperature sensing working mode and a non temperature sensing working mode, and has the advantages of simple structure, low manufacturing cost, convenient to mount and use and wide in the range of applicable occasions and the like, the appearance is of a cylindrical tee structure and water resource is saved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a temperature-sensing reversing valve for automatically switching medium flow channels according to the temperature of the medium entering the valve. Background technique [0002] Modern homes, hotels or schools are all equipped with domestic hot water supply systems. The hot water supply system transports hot water to the hot water use end through the conduit; when the hot water use end does not use hot water for a long time, the water temperature in the conduit and the temperature of the conduit will cool down to below the ideal temperature; When using water, it is necessary to release the cold water in the conduit first, and the hot water will only flow out after the conduit is heated by the hot water. The following problems will occur in this way: 1) the user must constantly feel and judge the water temperature when releasing the water, which is inconvenient to use; 2) if the...

Problems solved by technology

[0004] In order to solve the disadvantages of inconvenient use, complex structure, high manufacturing cost, inconvenient installation and weak adaptability to the use environment of the existing hot and cold water switching valves, the present invention provides a medium flow channel that can be automatically switched according to the temperature of the medium entering the valve. The temperature-sensing reversing valve includes a valve body, a temperature-sensing reversing valve core, a temperature-sensing switching assembly and a valve body blocking assembly; the valve body is provided with a medium inlet channel, a low-temperature medium outlet channel and a high-temperature medium outlet channel One end of the medium inlet channel, the low-temperature medium outlet channel and the high-temperature medium outlet channel are connected in the valve body; the temperature-sensitive reversing valve core is arranged in the valve body where the three channels communicate with each other The position is used to switch the medium flow channel between the low-temperature medium outlet channel and the high-temperature medium outlet channel; One end is used to switch the temperature-sensitive reversing valve core to enter the temperature-sensing mode or the non-temperature-sensing mode; the valve body blocking cover assembly is arranged on the valve body at one end of the high-temperature medium outlet channel
