● 安装

青海快31 锯下合适长度的无缝钢管,去除端口处毛刺。管子端面要与轴线垂直,角度公差不大于0。5°。如果管子需要折弯,则从管子端面至弯曲部位的直线段长度不能少于三倍螺母长度。

2 把螺母和卡套套在无缝钢管上。注意螺母和卡套的方向,不要装反了。

3 在预装配接头体螺纹和卡套上涂上润滑油,把管子插入接头体, (管子一定要插到底)用手旋紧螺母。

4 拧紧螺母直至卡套卡住管子,这个转折点可以通过拧紧力矩的增加感觉到(压力点)。

5 达到压力点后,再将压紧螺母拧紧1/2圈。

6 将预装配接头体拆下,检查卡套刃边的嵌入情况,可见的突起带必须填满卡套端面的空间。卡套可以稍旋转,但不能轴向推移。

7 最终安装,将实际安装中的接头体的螺纹涂上润滑油、压紧螺母与之配合拧至可感觉到的拧紧力增加为止.接着再拧紧1/2圈安装完毕。

● 重复安装

所有的卡套接头都可以多次重装,但要保证零件无损坏且清洁。

1 把管子插入接头体直至卡套贴紧接头体内锥面,用手拧紧螺母。

2 用扳手拧紧螺母,直至拧紧力矩急剧增大,再拧紧1/4至1/2圈即可。

● 检查

可拆下管子检查装配是否合乎要求:卡套端部的管子上应该有均匀的轻微凸起。卡套不能前后滑动,但允许有轻微转动。

● 泄漏原因

1 管子没插到底。

2 螺母没有拧紧。

Low installation

Saw off the suitable length of seamless steel tube to remove the burr at the end. The end face of the pipe shall be perpendicular to the axis, and the Angle tolerance shall not be greater than 0.5°. If the pipe needs to be bent, the straight line from the end of the pipe to the bend shall not be less than three times the length of the nut.

Put the nut and the sleeve on the seamless steel tube。 Pay attention to the direction of the nut and the sleeve。

Apply lube oil to the thread of the preinstalled fitting body and the clamp sleeve, insert the pipe into the fitting body, (the pipe must be inserted to the bottom) and tighten the nut by hand.

Tighten the nut until the sleeve catches the pipe。 This turning point can be felt by increasing the tightening torque (pressure point)。

5. After reaching the pressure point, tighten the compression nut by 1/2 turn.

Remove the preassembled fitting body and check the embedding of the sleeve edge. The visible protruding belt must fill the space of the end face of the sleeve. The sleeve can be rotated slightly, but not pushed axially.

7. For final installation, coat the threads of the joint body in the actual installation with lubricating oil and tighten the nut with it until the tightening force can be felt is increased.

● repeat installation

All sleeve joints can be reloaded several times, but the parts must be clean and free of damage.

1。 Insert the pipe into the connector body until the sleeve fits the cone inside the connector body, and tighten the nut by hand。

2. Tighten the nut with a wrench until the tightening torque increases sharply, and then tighten 1/4 to 1/2 turn.

Low check

Remove the pipe to check the fitting: the pipe at the end of the sleeve should have an even slight bump。 The sleeve cannot slide back and forth, but slight rotation is allowed。

● cause of leakage

The pipe is not inserted to the bottom。

2 the nut is not tightened.
