Abstract

The invention relates to the field of air conditioners, in particular to a four-way valve in an air conditioner, and particularly provides a manufacturing technology of a four-way valve coil. The manufacturing technology comprises the following steps of forming an installing neck on a wire rack body, arranging an insulating resin layer on the outer surface of the wire rack body, forming at least one limiting groove in the insulating resin layer, installing coil windings on the wire rack body, then fixedly installing a second baffle in the installing neck, examining the appearance of the coil windings, detecting the coil resistance and interturn high voltage of the coil windings, and conducting soaking testing and voltage withstanding testing; selecting the four-way valve coil with the qualified coil windings for subsequent manufacturing. By means of the manufacturing technology of the four-way valve coil, the four-way valve coil which is convenient to maintain and replace can be obtained, the problems are solved that a traditional four-way valve coil is difficult to dismantle as a whole and time and labor are wasted, the time and labor can be saved, and the efficiency can be improved; meanwhile, the obtained four-way valve coil can guarantee the stability of the installed coil windings, the interference of an external working environment is avoided, then the stability is improved, and the service life is prolonged.

Description

Technical field: [0001] The invention relates to the field of air conditioners, in particular to a four-way valve in an air conditioner, and specifically provides a manufacturing process of a four-way valve coil. Background technique: [0002] At present, most of the air conditioners can realize the switching of functions such as cooling, heating or defrosting, which is achieved by changing the flow direction of the refrigerant through the four-way valve in the air conditioner; the commonly used four-way valve includes a pilot valve, a main valve and a solenoid coil. Wait for at least three parts, use the electromagnetic force generated by the solenoid coil to drive the valve block in the pilot valve and make it move left and right, and generate a pressure difference on both sides of the valve block to drive the main valve, where the solenoid coil is a four-way valve reversing Critical power components for system flow control and shut-off. In order to ensure the stability a...
