DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1-2 As shown, the vacuum cooling sizing tester provided by the utility model comprises a vacuum sizing box body 1 and a cooling water pipeline. A thermocouple 2 and a water level controller 3 are arranged in the vacuum sizing box body 1. The thermocouple 2 is used to measure the water temperature in the vacuum sizing box body 1. The water level controller 3 is used to measure the water level in the vacuum sizing box body 1. The cooling water pipeline is arranged below the vacuum sizing box body 1. The cooling water pipeline comprises a water inlet pipe 4 and a water supply pipe 5. A water inlet solenoid valve 6 is arranged between the water inlet pipe 4 and the vacuum sizing box body 1. The water inlet solenoid valve 6 is fixedly installed on the vacuum sizing box body 1. The water inlet pipe 4 is connected to an external water source. The water inlet solenoid valve 6 controls the opening and closing of the water inlet pipe 4. When the water inlet solenoid valve 6 is opened, the outside The cooling water can enter the vacuum sizing box body 1, and the two ends of the water supply pipe 5 are respectively connected to the water inlet and the water outlet of the vacuum sizing box body 1, one end of the water supply pipe 5 is connected to the water inlet of the vacuum sizing box body 1, and the other end of the water supply pipe 5 is connected to the water outlet of the vacuum sizing box body 1 through a water pump 7. The circulation of the cooling water in the vacuum sizing box body 1 can be achieved by starting the water pump 7. A drain pipe 8 is arranged below the vacuum sizing box body 1, and the drain pipe 8 is respectively connected to the vacuum sizing box body 1 and the water supply pipe 5 through a branch pipe 9. The cooling water in the vacuum sizing box body 1 can be discharged through the drain pipe 8. A drain solenoid valve 10 is arranged on the drain pipe 89, and the drain solenoid valve 10 controls the opening and closing of the drain pipe 8.

[0016] A filter 11 is provided between the water supply pipe 5 and the water pump 7. The filter 11 filters the cooling water in the vacuum sizing box body 1 to ensure the cleanliness of the water source.

[0017] The water level controller 3 includes a float and a contact sensor. The liquid level is calibrated by the float, and the position of the float is sensed by the contact sensor. When the liquid level reaches the critical point set by the vacuum sizing box body 1, the float reaches the top, and the contact sensor senses the float position and sends out the liquid level position information.
