An electromagnetic coil assembly of a four-way valve used in a refrigeration system

Abstract

The invention discloses a magnetic coil assembly of a four-way valve for a refrigerating system. The magnetic coil assembly comprises a valve seat and a valve body, the connecting pieces are arrangedbetween the valve seat and the valve body, and the valve seat and the valve body are connected through the connecting pieces; the periphery of the valve body is provided with a winding which can generates electromagnetic force after being electrified to push the valve body to move, and one side, facing the valve seat, of the valve body is provided with a receiving groove, and the connecting piecesare located in the receiving groove; and the connecting pieces comprise a cylinder, a plunger, a spring and a connecting rod, the plunger and the cylinder are both located in the cylinder, the back of the plunger and the inner bottom surface of the cylinder are separately and fixedly connected with both ends of the spring, one end of the connecting rod is connected with the plunger, the other endof the connecting rod is connected with the valve seat, the cylinder is coincident with the receiving groove, the cylinder is inserted into the receiving groove, and the side surfaces of the valve body and the cylinder are separately provided with a first air pipe and a second air pipe. The magnetic coil assembly of the four-way valve for the refrigerating system has good heat dissipation performance.

Description

Technical field [0001] The invention relates to the field of valves, in particular to an electromagnetic coil assembly of a four-way valve used in a refrigeration system. Background technique [0002] The principle of refrigeration of general refrigerators The compressor's role is to compress the lower pressure vapor into higher pressure vapor, so that the volume of the vapor is reduced and the pressure is increased. The compressor sucks in the lower-pressure working fluid vapor from the evaporator, increases its pressure and sends it to the condenser, where it is condensed into a higher-pressure liquid. After being throttled by the throttle, it becomes a higher pressure liquid. After the low liquid, it is sent to the evaporator, where it absorbs heat and evaporates to become a lower pressure vapor, and then is sent to the inlet of the compressor to complete the refrigeration cycle. [0003] Four-way valve, a term for hydraulic valve, is a control valve with four ports. The four-...

AI Technical Summary

Problems solved by technology

Four-way valves are often used in refrigeration systems, but the electromagnetic coils of the current four-way valves do not have the heat dissipation function, the temperature rises, and the long-term overload work causes the current situation of burning out.
