[ detailed description ] of the invention
Examples:
referring to fig. 1, the present embodiment is a water temperature machine 100 with water return and pumping function, which sequentially includes a water inlet pipe 1, a circulating water outlet pipe 22, a client device 2, a circulating water return/water and air intake shared pipe 23, a water outlet pipe 3, a circulating pump 4 and a heater 5 arranged on the circulating water outlet pipe 22, a water return/water and air intake shared pipe 6 for communicating the circulating pump 4 with the water outlet pipe 3, a water inlet two-way valve 7 for controlling the input end of the water inlet pipe 1 to be disconnected and connected, a first check valve 8 arranged on the circulating water return/water and air intake shared pipe 23 and connected towards the water outlet pipe 3, and an exhaust valve 9 arranged between the first check valve 8 and the client device 2.
The embodiment is also provided with a bypass pipe 10 with one end communicated with the circulating water outlet pipe 22 and the other end communicated with the circulating water return/water pumping air inlet shared pipe 23, and the bypass pipe 10 is provided with a second check valve 11 which is communicated towards the direction of the water outlet pipe 3.
The inlet tube 1 still is provided with filter 12 and pressure switch 13 at the input, filters impurity to the aqueous medium that gets into among the circulation system, improves the protection to the inside environment of system, improves client device's life, monitors the inside pressure size of system through pressure switch 13.
A pressure gauge 14 and a first temperature sensing line 15 are arranged on the circulation outlet pipe 22 downstream of the heater 5 for monitoring the pressure and temperature of the aqueous medium entering the client device 2. The inlet pipe 1 is also provided with a hot water outlet ball valve 16.
A hot water inlet ball valve 17, a second filter 18 and a second temperature sensing line 19 are arranged on the circulating backwater/pumping air inlet common pipe 23 at the output end of the client device 2.
The water inlet two-way valve 7 is normally open.
A water outlet two-way valve 20 and a third filter 21 are arranged on the water outlet pipe 3 at the outlet port end.
In the present embodiment, when temperature control of the client device 2 is required.
In the constant temperature cooling stage, the water inlet two-way valve 7 is in a normal-way state, the water outlet two-way valve 20 is opened, the exhaust valve 9 is automatically exhausted or closed according to the state of the system, the heater 5 is closed, meanwhile, the circulating pump 4 rotates positively, cooling water enters the system under the action of the circulating pump 4 through the water inlet pipe 1, enters the client device 2 through the heater 5 and the circulating water outlet pipe 22, and then is output to the outlet end through the circulating water return/water pumping air inlet common pipe 23, the first check valve 8, the water outlet two-way valve 20 and the water outlet pipe 3.
