Abstract
The utility model discloses a constant-temperature adjusting device which comprises a three-way valve, a pressure sensor and a temperature controller. The three-way valve comprises a handle, a valve body, a valve core and a valve rod. The valve core is mounted in the chamber of the valve body. One end of the valve rod is fixedly inserted into the valve core, and the other end is hinged with the handle. The valve body is provided with two liquid outlets and a liquid inlet. The liquid outlets and the liquid inlet are respectively connected with a liquid outlet pipe and a liquid inlet pipe. The liquid outlet pipe and the liquid inlet pipe are respectively provided with a pressure sensor. The liquid inlet pipe is furthermore connected with the temperature controller. The pressure sensors and the temperature controller are electrically connected with the controller. The constant-temperature adjusting device has advantages of: simple pipe connection, and convenient operation.
Description
Technical field
The utility model belongs to technical field of valve control, relates in particular to Constant temp. regulating device.
