- Place the screw back into the relief valve disc and tighten. 将螺丝放回到安全阀阀瓣内，并加以紧固。
- SPECIFY: Energized to open or energized to close main valve. 具体说明:通电后开启还是通电后关闭主阀。
- He checked the flow of water by shutting off the main valve. 通过关上主阀他中断了水流。
- TO CLEAN: Inspect or replace worn valve disc, disconnect control pipe and unscrew bonnet from valve body using blunt tool and hammer on bonnet lugs. 清洗：检查或更换磨损的阀门阀瓣，断开控制管线，采用钝工具和锤打阀盖凸耳从阀体上旋下阀盖。
- The following procedures provide information for replacing the diaphragm, the relief valve disc, and the relief valve seat. 下列提供的资料是更换隔膜、安全法阀瓣和安全法阀座的程序。
- When this occurs, the valve disc moves to the closed position aided by the resetting shaft spring and line pressure, cutting the gas flow. 如此一来，阀门封盘藉由复归轴上的弹簧与管内压力，移到关闭位置而切断瓦斯气流。
- GDC-JQelectro high vacuum butterfly valve uses electromagnetic force to directly drive valve disc working. thus to make valve opened ro closed. GDC-J型电磁高真空挡板阀是以电磁力为动力直接带动阀板动作，使阀门开启或关闭。
- The main valve and pilot system can be serviced without removing the valve from the line. 不需要从管线上拆卸阀门,就可以对主阀和引导系统进行维修。
- Using a phillips screwdriver, remove the screw in the relief valve disc and replace the disc if required, or clean the existing disc. 用十字形螺丝刀，拆卸安全阀阀瓣内的螺丝，如果需要则进行更换，或者清洗原有的阀瓣。
- While unscrewing the injector button head, a second wrench must be used to assure that the injector body is not loosened from the main valve. 在拧松注入器圆头螺栓时，要用第二个扳手固定住注入器，防止其从主阀门上松落下来。
- The high capacity accelerator assures quick valve response to the solenoid signal regardless of the main valve size. 这种高性能加速器确保阀门能够迅速反应电磁阀信号，而与主阀通径无关。
- Electro High Vacuum Flapper Valve GDC-JQelectro high vacuum butterfly valve uses electromagnetic force to directly drive valve disc working. thus to make valve opened ro closed. GDC-J型电磁高真空挡板阀是以电磁力为动力直接带动阀板动作，使阀门开启或关闭。
- Supply power to sootblower, push down start button, the main valve will open and close automatically. 对电动机、行程开关应有保护装置。经过载能自动跳阀，并向主控制室报警。
- The main valve spindle incorporates an inner spindle for double regulation memory stop and valve position setting. 主阀轴配置一个内轴，适用于双重调节止动记忆和阀门位置设置。
- Where service conditions warrant larger-than-standard by-passes, it is recommended that the installation of the by-passes be around the main valve. 在应用条件允许安装较大的旁路的地方,建议旁路的安装要环绕着主阀门。
- General requirements to the procedure design: 1. Supply power to sootblower, push down start button, the main valve will open and close automatically. 对程序控制设计的一般要求是:1、接通线路电源开关,电源开启后,只需按起动按钮,吹灰管道的总阀即以自动开启、关闭;各吹灰器能按固定程序或选择程序一个个地或成组顺序动作,进行吹灰;吹灰结束后,总阀能自动关闭。
- Straight moving type relief valves, mainly valve disc, valve body,, spring-loaded, roof, regulation pole, conditioning nut, and other integral parts. 直动型溢流阀，主要有阀芯、阀体、弹簧、上盖、调节杆、调节螺母等零件组成。
