Technical Field

[0001] This utility model belongs to the field of filling gun technology, and more specifically, it relates to an integrated filling gun with three valves and two channels. Background Technology

[0002] A refrigerant charging gun, also known as a refrigerant charging nozzle or refrigerant coupler, is a professional handheld tool used in the installation, repair, and maintenance of air conditioning and refrigeration equipment. Its core function is to establish a fast, safe, controllable, and sealed connection channel between the refrigeration system (such as air conditioners, refrigerators, and cold storage) and the refrigerant cylinder or recovery machine, so as to carry out operations such as refrigerant charging, recovery, or pressure measurement.

[0003] Based on existing technology, it has been found that when using existing charging guns to vacuum and charge refrigerant in refrigerators, air conditioners, etc., the vacuum must be evacuated first before charging the refrigerant. The charging is generally done quickly, resulting in poor charging accuracy. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This device is equipped with a switching valve and a solenoid valve. By rotating the switching valve, the valve core inside rotates within the flow channel, which can change the connection state of the internal channels of the main body. The solenoid valve can close a set of channels by opening and closing it. A vacuum pump connected to the external pipe can be used to evacuate the equipment. During charging, the solenoid valve on the evacuation side is closed to achieve a slow charging method for refrigerant. When charging is complete, the solenoid valve on the other side is closed. Using slow charging can optimize the charging accuracy and fully guarantee the cooling effect of the refrigerator and freezer without repeated plugging and unplugging. Attached Figure Description

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0018] Example: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a three-valve dual-channel integrated filling gun, including a main body 1; The main body 1 is a three-valve dual-channel filling gun body; the main body 1 is equipped with a shell 2; the bottom of the main body 1 is equipped with a bottom tube 3; the discharge port at the top of the bottom tube 3 corresponds to the inlet at the bottom of the main body 1; the bottom of the bottom tube 3 is equipped with a connecting tube 4; the side of the main body 1 is equipped with a connector 5; the top of the main body 1 is equipped with a solenoid valve 6; the other side of the main body 1 is equipped with a switching valve 7; the switching valve 7 is used to switch between filling and vacuuming modes, and the solenoid valve 6 achieves fast or slow filling by opening and closing. When the coil is powered on, the current flows through the coil and generates a strong, concentrated magnetic field. This coil is called an electromagnetic coil. The magnetic field generated by the coil will attract the valve core, causing it to overcome the spring force or its own weight and move upward. The movement of the valve core will directly open or close a small hole on the valve body. This is the basic working principle of the solenoid valve 6.

[0019] The main body 1 has a flow channel inside; two sets of channels are set at the top of the main body 1; the channel in the middle of the top of the main body 1 is connected to the channels on both sides; through the two sets of channels and controlled by the solenoid valve 6, the vacuuming or refrigerant charging can be achieved by opening and closing the solenoid valve 6.

[0020] Among them, the bottom of the bottom tube 3 is provided with two sets of channels.

[0021] Among them, connector 5 is set to correspond with switching valve 7.

[0022] Among them, there are three sets of solenoid valves 6; the bottom of solenoid valve 6 and the top of the main body 1 are respectively set with two sets of channels.

[0023] The switching valve 7 is equipped with a control handle; the switching valve 7 is inserted into the flow channel of the main body 1.

[0024] The specific usage and function of this embodiment are as follows: In this invention, when using the device, it is connected to the equipment requiring refrigerant charging and vacuuming via connector 5. By manually operating the switching valve 7 to rotate, the valve core inside the main body 1 rotates within the flow channel, changing the connection state of the internal channels of the main body 1. Furthermore, the solenoid valve 6 can be used to close a set of channels. A vacuum pump connected to the external vacuum pump via connecting pipe 4 is used to vacuum the equipment. During charging, the solenoid valve 6 on the vacuuming side is closed to achieve a slow-to-fast refrigerant charging method. When charging is complete, the solenoid valve 6 on one side is closed, allowing the refrigerant to flow through the small channels inside the flow channel. This slow charging method optimizes the charging accuracy and fully ensures the cooling effect of the refrigerator or freezer without the need for repeated plugging and unplugging.
