Butterfly Valve Installation & Maintenance Manual

安装说明

Installation Description

协羽蝶阀是设计用于管路系统连接，两个法兰间的连接或一个法兰间的连接或一个法兰间的连接用于一边已经固定的管路系统。蝶阀的把手（或齿轮箱）是可以反转或正转180度操作。协羽的蝶阀安装设计是使用方形螺丝，螺母及华司所组成。

Hsieh Yu butterfly valve is designed for pipeline system connection between two flanges or with one flange for connection with the pipeline system of which one side has been fixed. The handle (or gear box) of butterfly valve can be rotated backward or forward for 180 degrees. Hsieh Yu butterfly valve is designed for installation with square screw, nut and washer.

第一步骤

Step 1

将管路上的法兰部分，要求及安装步在本手册里。【注意】管路上的紶兰将要求精确的对正螺丝孔位置及想要的阀门位置。

Installation procedures, requirement for the flanges in the pipeline system have been stated in this Manual.[Note]: It is required that flanges on the pipeline have to be aligned accurately with the screw holes and the desired position of the valves.

第二步骤

Step 2 

检查管路两法兰的螺丝孔的是否有对正及预留的间隙。管路法兰必须平行对正并且必须预留空系使阀门能放入。

Check the screw holes of two flanges in the pipeline for alignment with reserved clearance. Flanges in the pipeline have to be aligned in parallel and clearance has to be reserved for putting the valve in.

第三步骤

Step 3

将阀门转到关闭的位置，将阀门放入，安装螺丝，螺母及华司，然后用手锁紧。

Rotate the valve to [CLOSE] position, put in the valve and install screw, nut and washer, then, tighten them up with hand.

第四步骤

Step 4

将阀门打开同时检查X轴方向偏差及阀体叶片的操作范围。管路中心线的误差不可超过1/8”。假如有需要时调整阀门的位置。使用对角的相对位置依序将螺丝锁紧，然后将法兰螺丝以每5ft-ibs的扭力增加锁到要求的规范为止。千万不要试着去将多余的空隙在不允许的范围内之强制锁合。

Open the valve and check X axis deviation and operation range of the valve blades. Deviation of the center line of pipeline shall not exceed 1/8”. If it is necessary to adjust the position of valve, just tighten up the screws in order by use of the diagonal opposite positions, then, lock up the flange screws with the torque increment of 5ft-lbs until specified requirement is met. Don’t try to force a lock-up in the excessive clearance within the range not allowed.
