General purpose industrial valves-Diaphragm valves
GB/T12239-1989通用阀门隔膜阀
2.
Diaphragm valves cannot be repaired or adjusted in the field.
不能在现场修理或调整隔膜阀。
3.
Operating Principle: The tied-diaphragm valve is a handwheel-operated valve, utilizing a two-piece stem connected through the diaphragms.
运转原理：束缚隔膜阀是采用通过横膈膜连接的两个阀杆的手轮型阀门。
4.
Recommended Opening Procedure: The diaphragm valve handwheel rotates about 1 1 /4 turns from fully open to closed.
推荐的开启程序：从彻底打开到关闭，隔膜阀手轮旋转大约11/4圈。
5.
When opening a diaphragm valve, you will feel resistance for approximately one turn, at which point most or all resistance on the handwheel will disappear.
当开启隔膜阀的时候，在大约一圈中，你会感觉到阻力，到了一圈时，大部分或所有阻力都会消失。

Remove the relief valve cover, stem/diaphragm assembly, and relief valve spring.
拆卸安全阀阀盖，阀杆/隔膜总成，和安全阀弹簧。
8.
Lift pressure plate (7) to withdraw diaphragm and stem from valve.
提升压力板(7)，从阀门内退出隔膜和阀杆。
9.
The stem and diaphragm assembly will normally remain with the cover as it is removed.
阀杆和隔膜总成通常附在阀盖上与阀盖一起拆离。
10.
Remove the cover and diaphragm. The relief valve piston assembly can be lifted straight up and out.
拆卸阀盖和隔膜。安全阀活塞总成可以笔直提出到外面来。
11.
To replace the relief valve disc, hold the upper guide fin and unscrew the diaphragm pressure plate.
要更换安全阀阀瓣，握住上部引导翼，旋下隔膜压力板上的螺丝。

The Royal is a diaphragm-type valve and was the original product of Sloan Valve Company when it started in business in 1906.
Royal阀是一种隔膜式阀门,是美国思龙阀门公司最早的产品,从1906年就开始生产。
13.
Be sure to always install regulator with the arrows under the diaphragm flange pointing in the direction of flow.
确保安装调节阀时，始终保持隔膜法兰下的箭头指向流体流向。
14.
Remove the piston and spring from the relief valve housing and thoroughly clean all parts including the diaphragm.
从安全阀外壳上拆卸活塞和弹簧，彻底清洗包括隔膜的所有部件。
15.
Preferred position for 2300 valves is in a horizontal line with spring chamber up.
对于系列2300阀门，首选的安装位置是在水平管线上，其弹簧隔膜朝上。
16.
Leaks can occur along the valve stem through the packing or diaphragms. Leaks of this type can be stopped by closing the valve and venting any pressure from the outlet.
泄漏可能沿着阀杆通过衬垫或隔膜发生。关闭阀门，从排气口排出压力可以停止这种泄漏。
17.
The valve shall be constructed with a molded diaphragm separating the air inlet from the potable water supply to prevent spillage.
这种阀门应该配置一个模压隔膜，将空气进口与饮用水供水管道隔离开来，以防止泄漏或溢出。
