Problems solved by technology

When the existing refrigerant charging gun is docked with the equipment to be filled, the gun body is large in size and heavy in weight, and it is necessary to forcefully open the self-sealing joint of the equipment to be charged by manpower, which is easy to cause the filling process. The filling pipe of the equipment is deformed and the vacuum degree in the filled equipment rises. In terms of filling, the filling volume is small and the filling speed is slow.

Abstract

The invention relates to the technical field of refrigerant filling, in particular to a large-dose gun head for refrigerant filling. The large-dose gun head comprises a valve body, a refrigerant filling pipe, a refrigerant channel component, a vacuumizing electromagnetic valve, a filling electromagnetic valve component, a pushing needle, a switch seat and a connecting head. The surface, corresponding to the vacuumizing electromagnetic valve, of the valve body is provided with an exhaust port. An exhaust channel penetrating through the valve body is arranged between the vacuumizing electromagnetic valve and the exhaust port. A wrench is arranged on the connecting head. Through the wrench on the connecting head, the connection head can be connected with filling equipment more conveniently, and the operation is simpler. A self-sealing joint of equipment filled with refrigerant is pushed open by the pushing needle, and gases in the equipment filled with refrigerant and the valve body can be quickly discharged from the exhaust channel by the vacuumizing electromagnetic valve to achieve a vacuum effect and ensure that the vacuum degree in the equipment filled with refrigerant does not rise. A first electromagnetic valve, a second electromagnetic valve and a third electromagnetic valve are connected with a first passage, a second passage and a third passage through the valve body in aconduction mode correspondingly, thereby improving the characteristics of large refrigerant injecting dose and high speed.

Description

technical field [0001] The invention relates to the technical field of refrigerant charging, in particular to a large-dose gun head for refrigerant charging. Background technique [0002] Refrigerant is the working substance that circulates continuously in the refrigeration system to achieve refrigeration. In the case of insufficient refrigerant, the refrigeration function of the equipment using refrigerant will be affected. At this time, it is necessary to replenish the refrigerant to restore the refrigeration function of the equipment. When the existing refrigerant charging gun is docked with the equipment to be filled, the gun body is large in size and heavy in weight, and it is necessary to forcefully open the self-sealing joint of the equipment to be charged by manpower, which is easy to cause the filling process. The filling pipe of the equipment is deformed and the vacuum degree in the filled equipment rises. In terms of filling, the filling volume is small and the fi...
