[0008] The invention provides a high-efficiency composite flash drum pump unit, which has the following beneficial effects: by adding a float valve and a liquid level valve, wherein the float valve is used to detect the liquid level height inside the low-pressure circulation drum, so that the liquid level valve can automatically supply liquid to the inside of the low-pressure circulation drum; by adding a magnetic flap liquid level gauge and an electromagnetic valve, liquid can be continuously supplied to the inside of the low-pressure circulation drum when the float valve and the liquid level valve fail, so that not only the low-pressure circulation drum can continue to work, but also people can be convenient for maintenance; by adding a first float liquid level controller and a second float liquid level controller, it can be used to detect the height of the liquid level of the aqueous solution in the low-pressure circulation drum, and when the alarm time of the first float liquid level controller and the second float liquid level controller exceeds the set time, the main control motherboard will stop all the electrical equipment connected to the low-pressure circulation drum and the flash drum, so as to achieve a protective effect; by adding a flash drum, the liquid refrigerant can be supercooled when passing through the inside of the flash drum, so as to increase the refrigeration capacity of the liquid refrigerant, so that the liquid refrigerant no longer needs special equipment for supercooling.

DETAILED DESCRIPTION

[0011] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0012] Reference Figure 1 A high-efficiency composite flash barrel pump unit includes a flash barrel 12 and a barrel body 11 of a low-pressure circulation barrel. A safety valve 13 and a pressure gauge 1 are installed in sequence on the top of the barrel body 11. The electrical equipment on the flash barrel 12 and the low-pressure circulation barrel is also electrically connected to an external main control motherboard.

[0013] The flash barrel 12 is connected to a liquid supply pipe through an electric pilot valve 14, and a filter 6 is installed at one end of the liquid supply pipe away from the electric pilot valve 14. The filter 6 is respectively connected to a liquid level valve 3 and a solenoid valve 5 through pipelines. The solenoid valve 5 is connected to a throttle valve 10 through a pipeline, and the throttle valve 10 is communicated with the interior of a barrel body 11 through a pipeline. The liquid level valve 3 is communicated with the interior of the barrel body 11 through a pipeline, and the liquid level valve 3 is also connected to a liquid supply throttling pilot valve 4. The liquid supply throttling pilot valve 4 is connected to a float valve 2 through a pipeline, and the float valve 2 is communicated with the interior of the barrel body 11. By adding the float valve 2 and the liquid level valve 3, the float valve 2 is used to detect the liquid level height inside the low-pressure circulation barrel, so that the liquid level valve can automatically supply liquid to the interior of the low-pressure circulation barrel.

[0014] A magnetic flap level gauge 9 is also provided on the outside of the barrel body 11, and the two ends of the magnetic flap level gauge 9 pass through the top and bottom of the barrel body 11 respectively through pipes, and extend to the interior of the barrel body 11, and the magnetic flap level gauge 9 is electrically connected to the solenoid valve 5. By adding the magnetic flap level gauge 9 and the solenoid valve 6, liquid can continue to be supplied to the interior of the low-pressure circulation barrel when the float valve 2 and the liquid level valve 3 fail. This not only allows the low-pressure circulation barrel to continue to work, but also makes it convenient for people to carry out maintenance.

[0015] A first float liquid level controller 7 and a second float liquid level controller 8 are provided on the outside of the barrel body 11 in sequence from top to bottom, and the first float liquid level controller 7 and the second float liquid level controller 8 are both connected to the interior of the barrel body 11, and the electric pilot valve 14, the first float liquid level controller 7 and the second float liquid level controller 8 are electrically connected to the main control motherboard. By adding the first float liquid level controller 7 and the second float liquid level controller 8, it can be used to detect the height of the aqueous solution in the low-pressure circulation barrel. When the alarm time of the first float liquid level controller 7 and the second float liquid level controller 8 exceeds the set time, the main control motherboard will stop the electrical equipment connected to the low-pressure circulation barrel and the flash barrel, thereby achieving a protective effect.

[0016] A stop valve is fixedly connected to the pipeline between the filter 6 and the electric pilot valve 14, stop valves are fixedly connected to the pipelines on both sides of the liquid level valve 3, and a stop valve is fixedly connected to the pipeline between the solenoid valve 5 and the filter 6. The stop valve can cut off the delivery of liquid refrigerant when the filter element of the filter 6 is replaced, thereby facilitating the replacement of the filter element of the filter 6. The stop valve can also facilitate the replacement of other equipment by cutting off the liquid refrigerant in each passage.

[0017] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
