Embodiment Construction

[0024] figure 1 A joint according to one embodiment is shown. The joint is illustrated in an unengaged state. exist figure 1 Among them, the fluid can flow through a second opening 16 of the tool 12 , through a first channel 42 , through a relief channel 34 , through a second channel 32 , and through a first opening 14 . Therefore, when the relief valve 20 is connected, a built-in pressure in the different channels of the tool and the joint can be circulated and vented through the relief valve 20 . The technical effect of this is that the joints can be joined by normal hand strength. figure 2 The same joint is shown according to one embodiment, but here the joint is illustrated in an engaged state. As described later, in figure 2 In , the flow as described above is not possible because the release channel 34 is sealed by the sealing means 24 , 26 .

Abstract

A nipple for a coaxial coupling is disclosed. The nipple comprises a housing (40), and a nipple tube (30) arranged in the housing (40). The nipple comprises a first passage (42) between the housing (40) and the nipple tube (30), and the nipple tube (30) comprising a second passage (32) within the nipple tube (30). A relief valve (20) is slideably arranged in the nipple tube (30). The nipple comprises sealing means (24, 26) for sealing between the nipple tube (30) and the relief valve (20). The nipple tube (30) further comprises a relief passage (34), the relief passage (34) forming a fluid passage between the first passage (42) and the second passage (32). The relief passage (34) being arranged so that the sealing means (24, 26) seals the relief passage (34) when the nipple is fully coupled.

Description

technical field [0001] The present disclosure relates to a nipple. More specifically, the present disclosure relates to a joint for a coaxial coupling. More specifically, the present disclosure relates to a joint for a coaxial coupling and a swivel. Background technique [0002] Many hydraulic tools powered by hydraulic fluid require numerous couplings. These couplings supply hydraulic fluid to a hydraulic tool and return the hydraulic fluid from the tool to a fluid supply. A disadvantage of many couplings, especially many coaxial couplings, is that if a cold hydraulic tool with a joint (the male part, the female part not coupled with the coupling) is left In sunlight, the hydraulic oil in the joint and the tool expand and the pressure of the seal increases. Said pressure can reach hundreds of bars (tens of megapascals), which makes it impossible to vent said pressure to the open air by hand applying pressure to the coupling without the use of special tools . This has ...
