Floating coupling measurement apparatus

Abstract

A floating joint measuring device includes a sliding device and a measuring tube assembly. The sliding device includes a slide group and a fixed seat and a floating joint fixed seat disposed on the slide group; the fixed seat has an adapter, and the floating joint fixed seat has a floating joint unit disposed at an angle; thereby, the male and female ends of a quick-release joint under test are connected at a relative angle or at an angle that is not aligned with their center lines, and the displacement connection is automatically corrected before separation. The measuring tube assembly is connected to the floating joint unit and the adapter respectively through a connecting unit group to introduce a medium to measure the separation leakage and trapped air volume of the floating joint.

Claims

1. A floating joint measuring device, comprising: a sliding device including a slide group and a fixed seat and a floating joint fixed seat disposed on the slide group, the fixed seat being provided with an adapter, and the floating joint fixed seat being provided with a floating joint unit disposed at an angle, the adapter and the floating joint unit being used to connect a quick-release joint under test, so that the quick-release joint under test is connected at a relative angle or at an angle with inconsistent center lines and is automatically corrected for displacement connection and separation operation; a measuring tube group located above the sliding device, comprising a first measuring tube and a second measuring tube, the upper end of the first measuring tube having a first opening, and the lower end being connected to the floating joint unit through a first connecting unit group, the upper end of the second measuring tube having a second opening, and the lower end being connected to the adapter and the first connecting unit group through a second connecting unit group; wherein the first connecting unit group includes a first three-way valve, a first connecting pipe and a second connecting pipe, and the second connecting unit group includes a second three-way valve, a third connecting pipe and a fourth connecting pipe.

2. The floating joint measuring device as described in claim 1, wherein the sliding device further includes a base, and the slide assembly is disposed on the base; one end of the adapter is provided with a pipe connection portion, and the other end is provided with a test sample connection portion; the fixed seat is provided with a groove for placing the adapter.

3. The floating joint measuring device as claimed in claim 1, wherein the floating joint fixing seat has opposing side walls, the opposing surfaces of the side walls each having a mutually cooperating inclined surface, and the floating joint unit is disposed between the inclined surfaces.

4. The floating joint measuring device as described in claim 1, wherein the first and second measuring tubes are vertically and separately arranged.

5. The floating joint measuring device as claimed in claim 1, wherein: the first three-way valve is connected to the lower end of the first measuring tube and is connected to the floating joint unit through the first connecting tube, and is connected to the second three-way valve through the second connecting tube; the second three-way valve is connected to the lower end of the second measuring tube through the third connecting tube and is connected to the adapter through the fourth connecting tube.

6. The floating joint measuring device as described in claim 1, wherein the sliding device, the first and second measuring tubes, and the first and second connecting unit groups are mounted on a fixed back plate.

7. The floating joint measuring device as described in claim 6, wherein a vibrator is provided on the fixed back plate to eliminate air bubble interference during the test.
