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 refrigeration principle of a general refrigerator The function of the compressor is to compress the steam with a lower pressure into a steam with a higher pressure, so that the volume of the steam is reduced and the pressure is increased. The compressor sucks the lower-pressure working medium vapor from the evaporator, raises its pressure, and then sends it to the condenser, where it is condensed into a higher-pressure liquid, which becomes a higher-pressure liquid after being throttled by the throttle valve. After the low-pressure liquid is sent to the evaporator, it absorbs heat and evaporates in the evaporator to become a steam with a lower pressure, and then sends it to the inlet of the compressor to complete the refrigeration cycle. [0003] Four-way valve, hydraulic ...
