Problems solved by technology

[0002] When small fluid cooling or heating equipment is assembled on the production line, it is necessary to fill the interior with refrigerant liquid. In the past filling process, a spoon-shaped object and a funnel are usually used to scoop out the refrigerant liquid from the large box and then add it to the equipment. , the operation is cumbersome and inefficient
At present, fluid-driven devices (such as various electric pumps or electromagnetic pumps) are mainly used to pump out the brine liquid from the large tank and then inject it into related equipment. The efficiency has been improved, but there are still the following disadvantages: It is difficult to control the amount of filling, and it is often easy to cause dripping due to excessive addition, causing environmental pollution
The reason is that due to the hysteresis of the fluid in the delivery pipeline connecting the fluid drive device and the equipment to be filled, even if the fluid drive device has stopped, it is still impossible to prevent a large amount of liquid from flowing into the equipment to be filled in time

Abstract

The invention discloses a novel secondary refrigerant liquid filling gun, which comprises a gun-shaped shell, and is characterized in that: the gun-shaped shell is provided with a solenoid valve inside; the inlet and outlet of a valve core of the solenoid valve are respectively connected with a liquid inlet pipe and a liquid outlet pipe; the liquid inlet pipe extends out of the back end of the gun-shaped shell, while the liquid outlet pipe extends out of the front end of the gun-shaped shell; a gun handle position of the gun-shaped shell is provided with a micro-switch which is electrically connected with the solenoid valve; and a button of the micro-switch protrudes out of the gun-shaped shell. The outflow of the secondary refrigerant liquid is stopped in time through the solenoid valve in the novel secondary refrigerant liquid filling gun, so that the novel secondary refrigerant liquid filling gun can effectively control the filling quantity and prevent environmental pollution caused by leakage of the secondary refrigerant liquid.
