流体控制设备的制造方法、流体控制设备及接头用保护件
摘要：
本发明提供一种高效地制造流体控制设备(10)的方法、方法中所用的接头用保护件(20、30)及流体控制设备(10)。接头用保护件(20、30)以可拆卸的方式被安装于在接头套管(13)插通在螺母的贯通孔中的状态下被焊接于主干部(12)的接头套管(13)。接头用保护件(20、30)的主体部(22)具有直径比接头套管(13)的外直径大的内周面(21)，以使内周面(21)与接头套管(13)的围绕轴的外周面(13B)之间具有间隙，主体部(22)具备用于相对于接头套管(13)进行装卸的缝隙(24)。通过将接头用保护件(20)安装于接头套管(13)，来抑制螺母沿着轴向的移动，使得接头套管13的密封部不从螺母突出，从而保护密封部。能够保持将接头用保护件(20、30)安装于主干部(12)的状态不变地进行清洗。
摘要（英）：

Provided are: a method for efficiently producing a fluid control device (10); and protective equipment for joint (20, 30) and fluid control device (10) used in said method. These items of protective equipment for joint (20, 30) are detachably fitted to a joint sleeve (13) that is welded to a body (12), with the joint sleeve (13) inserted into the through-hole of a nut. The body (22) of the protective equipment for joint (20, 30) has an inner peripheral surface (21) having a larger diameter than the outer diameter of the joint sleeve (13) such that there is a gap with the outer peripheral surface (13B) of the joint sleeve (13), and the body (22) is equipped with a slit (24) to enable the body (22) to be attached to and detached from the joint sleeve (13). By fitting the protective equipment for joint (20) to the joint sleeve (13), movement of the nut in the axial direction is minimized, and the seal part of the joint sleeve (13) protects the seal part by ensuring that same does not protrude from the nut. Cleaning is possible with the protective equipment for joint (20, 30) fitted to the body (12).
