Description

Technical Field

[0001] The utility model belongs to the technical field of valve cores, and in particular relates to a solenoid valve core for controlling refrigerant. Background Art

[0002] In refrigerant control technology, solenoid valves, as key components for regulating refrigerant flow, are widely used in refrigerators, air conditioners, and other refrigeration equipment. Solenoid valve performance directly impacts the equipment's cooling performance, energy efficiency, and system reliability. However, existing refrigerant solenoid valves often suffer from issues, particularly in refrigerators and other refrigeration systems. These issues often lead to refrigerant leakage, slow response, and inaccurate temperature control, impacting the equipment's cooling performance and energy consumption.

[0003] Traditional refrigerant solenoid valves have flaws in the seal between the valve core and the valve seat, which can cause refrigerant leakage when the valve is closed. This not only wastes refrigerant resources but also prevents the equipment from maintaining stable cooling performance, increasing energy consumption. Refrigerant leakage can also affect the temperature control accuracy of the refrigerator, making it impossible to accurately adjust the temperature, thereby affecting the preservation of food.

[0004] In some traditional designs, the valve core may move slowly, resulting in inaccurate refrigerant flow regulation. This slow response prevents the solenoid valve from responding quickly to control signals, affecting the accuracy and timeliness of refrigerant flow. This not only affects the cooling performance of refrigerators and other refrigeration equipment, but can also cause temperature fluctuations, reducing the refrigerator's energy efficiency.

[0005] In view of this, overcoming the defects of the above-mentioned prior art is an urgent problem to be solved in this technical field. Utility Model Content

DETAILED DESCRIPTION

[0017] like Figures 1 to 2As shown, a refrigerant control solenoid valve core includes a valve body shell 10, an intake valve seat 20 and an exhaust valve seat 30, wherein a mounting groove 11 is opened in the middle of the valve body shell 10, and the mounting groove 11 is a hollow cylindrical groove. The intake valve seat 20 is mounted in the rear end of the mounting groove 11, and the exhaust valve seat 30 is mounted in the front end of the mounting groove 11, so that the intake valve seat 20 and the exhaust valve seat 30 are arranged correspondingly, and the intake valve seat 20 and the exhaust valve seat 30 are respectively fixed to the valve body shell 10 as a whole by welding. When in use, the mounting groove 11 of the valve body shell 10, the intake valve seat 20 and the exhaust valve seat 30 are fixed by welding, so that the volume of the entire solenoid valve core is effectively compressed, reducing unnecessary space waste. The smaller volume not only reduces the overall size of the equipment, but also facilitates installation in a small space. It is particularly suitable for cooling systems that require high efficiency and energy saving and have strict space requirements. It has sensitive response and long service life.

[0018] During specific implementation, the intake valve seat 20 is provided with an intake valve boss 21 at one end facing the exhaust valve seat 30, and the outer side of the intake valve boss 21 is provided with a valve core sealing gasket 22, and the outer side of the valve core sealing gasket 22 is provided with a valve core bracket 23. Magnet mounting positions 231 are symmetrically provided on both sides of the valve core bracket 23, and magnets 24 are respectively installed in the two magnet mounting positions 231. During use, when current passes through the electromagnetic coil and generates a magnetic field, the magnetic force acts on the magnet 24 on the valve core bracket 23 to push the valve core toward the exhaust valve seat, opening the refrigerant flow channel to allow the refrigerant to enter or be discharged.

[0019] During specific implementation, the valve core sealing gasket 22 is made of silicone material. In the valve core system, the silicone sealing gasket 22 is sleeved on the outside of the intake valve boss 21, and is responsible for sealing between the valve body shell 10, the intake valve seat 20 and the exhaust valve seat 30. When the solenoid valve is started, the valve core moves with the magnetic force, and the silicone sealing gasket 22 effectively prevents the leakage of the refrigerant, ensuring that the fluid flows accurately in the control valve.

[0020] During specific implementation, an exhaust valve boss 31 is provided at one end of the exhaust valve seat 30 facing the intake valve seat 20, and the exhaust valve boss 31 is arranged correspondingly to the intake valve boss 21. During use, when current passes through the electromagnetic coil to generate a magnetic field, the magnetic force acts on the magnet part on the valve core, pushing the valve core to move toward the exhaust valve seat. During this process, the cooperation between the intake valve boss 21 and the exhaust valve boss 31 ensures the seal between the valve core and the valve seat, thereby avoiding refrigerant leakage.

[0021] During specific implementation, the end of the intake valve seat 20 away from the exhaust valve seat 30 is connected to the intake pipe 25, and the end of the exhaust valve seat 30 away from the intake valve seat 20 is respectively connected to the first exhaust pipe 32 and the second exhaust pipe 33. When in use, the intake pipe 25 is used to introduce external gas or refrigerant into the solenoid valve system. The intake pipe 25 guides the gas into the valve core through the intake valve seat 20, and thereby controls the process of flowing to the exhaust pipe. The design of the first exhaust pipe 32 and the second exhaust pipe 33 enables the solenoid valve to select different exhaust paths as needed to distribute or adjust the fluid. Through the configuration of the first exhaust pipe 32 and the second exhaust pipe 33, more flexible airflow control can be achieved, and the flow direction of the refrigerant can be adjusted or distributed to different system components.

[0022] In summary, a mounting groove 11 is provided in the middle of the valve body shell 10, and the mounting groove 11 is a hollow cylindrical groove. The intake valve seat 20 is installed in the rear end of the mounting groove 11, and the exhaust valve seat 30 is installed in the front end of the mounting groove 11. The intake valve seat 20 and the exhaust valve seat 30 are respectively fixed to the valve body shell 10 as a whole by welding. The design of the refrigerant control solenoid valve core fixed by welding in the utility model effectively compresses the volume of the entire solenoid valve core, reduces unnecessary space waste, and has sensitive response and long service life.
