Chemtrol Chemcock and Calibrated Needle Valves are available in the configurations shown above. Since the needle is a globe design, flow must be in the direction indicated by the arrow. The Chemcock Valve is a ball design; therefore, flow can be in either direction. Listed is a summary of installation techniques. 螺纹连接阀门–参阅《Chemtrol热塑塑料管道技术手册》中的塑料螺纹连接指南。警告:不要过紧旋转螺纹。通常,如果必要的话,在感到手紧后,采用适当的固定扳手在旋转一至二圈即可。(ANSI B1.20.1定义通径DN25以下的阀门手紧含义是4至4.5圈螺纹。) Threaded Valves–Refer to the plastic thread joining instructions in the Chemtrol Thermoplastic Piping Technical Manual. Caution: Do not overtighten threads. Usually, one to two turns beyond hand tight, using a suitable strap-wrench, if necessary, is sufficient. (ANSI BI.20.1 defines hand-tight as 4 to 4 1/2 threads for sizes through 1". 软管连接端口阀门–将适当的的夹子滑到需要连接的软管上。用温水润滑软管的端口将有助于组装。将软管推到所有倒钩上,直到接头上搭板手的平面处。将夹子滑上并将最大的倒钩处于中心位置。夹紧夹子,但是不要过紧。 Hose End Valves–Slide a suitable clamp over the hose to be joined. Lubrication of the hose end with warm water may aid in assembly. Push the hose on and over all barbs and up to the wrench flats. Slide the clamp up and center over the largest barb. Tighten clamp, but do not overtighten. 调整–这些阀门已经在工厂组装并检测,不需要再进行调整。 Adjustment–Valves are factory assembled and tested with no adjustment required. |
