Method and device for coolant recycling

摘要

A method for replacing a volume of coolant fluid in a circulating system in diesel engine system that includes the steps of establishing pneumatic connection with at least one location in the diesel engine coolant fluid circulating system; establishing fluid connection with at least one point in the diesel engine coolant fluid circulating system, the fluid connection location being different from the pneumatic connection; and after pneumatic and fluid connection is established, drawing a vacuum pressure through said pneumatic connection and introducing the volume of coolant fluid through said fluid connection as well as a device for accomplishing the same.

1. A method for replacing a volume of coolant fluid in a circulating system in a diesel engine system comprising the steps of:
establishing pneumatic connection between an externally located pressurizable recycling tank and at least one location in the diesel engine coolant fluid circulating system; establishing fluid connection between the externally located pressurizable recycling tank and at least one point in the diesel engine coolant fluid circulating system, the fluid connection location being different from the pneumatic connection, wherein the volume of coolant fluid is resident in the externally located pressurizable recycling tank; after pneumatic and fluid connection is established, drawing a vacuum pressure through said pneumatic connection and introducing the volume of coolant fluid through said fluid connection, wherein the volume of fluid is introduced from the externally located reservoir through a float valve located in the externally located reservoir, wherein the float valve comprises:
a shaft body having an exterior surface, a first end and an opposed second end, the shaft body defining a single through shaft extending from the first end to the second end defining an interior area, the shaft body having at least one bore defined therein, the bore extending from the exterior surface to the single through shaft;a float member configured to traverse the interior area of the single through shaft, the float member having a height (H);at least one seated seal positioned at a fixed location in the single through shaft proximate to the first end of the shaft member, the seated seal configured to releasable contact the float member; andat least one stop member located proximate the second end of the shaft in contact with the shaft.
