Embodiment Construction
[0016] Refer to the following Figure 1-9 To describe the basic structure of the temperature-controlled differential pressure return faucet of the present invention and its working mode and status in different convenient environments.
[0017] Such as figure 1 and 2 As shown, the faucet includes a housing 1 , a cold water pipe 3 , a hot water pipe 5 , a water return valve plate 7 and a water return handle 9 . Wherein, the cold water pipe 3 enters the housing 1 from the rear end outside the housing temperature 1, communicates with the temperature control chamber 25 through the temperature control cavity return port 29 downwards, and opens upward into the circular open space on the top of the housing 1 and is connected with the fixed The cold water inlet 39 of the fixed valve plate of the mixed water valve in this space communicates; the hot water pipe 5 enters the shell 1 from the rear end of the shell 1 and communicates with the water inlet tank 11 of the return valve action...

A temperature control differential pressure backwater tap with water saving function comprises a valve mechanism capable of realizing pressure sensing, temperature sensing and interlocking. When a user turns a backwater handle to open a backwater valve, residual cold water in a hot water pipe enters a temperature control cavity from the lower valve plate of the backwater valve. When the water temperature fails to reach a preset temperature, the valve mechanism formed by a temperature control member and the temperature control cavity is in an open status, and a cold water pipe and the hot water pipe are enabled to be communicated with each other. The cold water in the hot water pipe enters continuously the cold water pipe under the action of pressure. With the backwater process, the water temperature in the temperature control cavity increases gradually, and the temperature control member displaces due to thermal expansion. When the water temperature reaches the preset temperature, the displacement of the temperature control member 31 finally cuts off the connection between the water inlet of the temperature control cavity and the water outlet of the temperature control cavity, thereby completing the backwater process. At that time, the can uplift a water handle to get water of desired temperature.
Description
technical field [0001] The present invention generally relates to a temperature-controlled differential pressure return faucet, in particular to a temperature-controlled differential pressure return faucet with a valve mechanism having the functions of temperature control, pressure sensing, jet delivery and potential energy recovery. Background technique [0002] With the rapid expansion of urban construction and the increase of urban population, environmental pollution and urban water shortage have increasingly become the top priority of restricting economic development. my country is especially a country short of water and energy. Most cities in the west and north of our country are short of water, while the east and south are short of electricity. These factors have seriously affected people's normal production and life. Water saving has arrived. When it is imperative. But in our daily life, we are facing a lot of helpless and unnecessary waste of water every day. When p...
