The linear floating valve plays a throttling role in the 19XR refrigeration unit and is a key component of the refrigeration unit.Its common fault modes include floating valve jam,insufficient air-bag volume and low refrigerant level.The linear float valve jam may be caused by wear or foreign mat-ter.By strengthening the management of foreign matter prevention and improving the structure of linear float valve,the consistency of its action can be improved,so as to reduce the jam.The linear floating valve is prone to the problem of insufficient airbag volume in the case of low temperature in winter,which can be alleviated by increasing the air intake or reducing the amount of gas liquefaction.Howev-er,the liquid level of refrigerant is low due to loss or leakage,which can be alleviated by timely detec-tion of low liquid level and supplement of refrigerant.
