QZMAT型气动薄膜隔膜调节阀  的详细介绍

概述Outline
QZMAT气动薄膜隔膜调节阀\QZMBT气动薄膜隔膜调节阀由多弹簧气动薄膜执行机构和隔膜阀组成。隔膜阀体流通平滑、节流元件为弹性隔膜阀,阀盖上无填料函。因而阀流通能力比一般调节阀大且无泄漏,在许用压差范围内可作切断阀用。气开、气关作用由正反执行机构实现。 该阀适用于高粘性流体、悬浮状颗粒、纤维介质和有毒介质、腐蚀性介质的调节场合。

QZMAT pneumatic diaphragm valve film \ QZMBT diaphragm valve pneumatic membrane pneumatic membrane by the multi-spring diaphragm actuators and components. Diaphragm valve body flow smoothly, cutting components for the elastic diaphragm, valve cover stuffing. Thus the valve control valve flow capacity than the average large and no leakage in the range of allowable pressure shut-off valve can be used. Open air, air to close by the pros and cons of the role of executive agencies to achieve. The valve is suitable for high viscosity fluids, like suspended particles, fiber media and toxic media, corrosive mediators occasions.


安装、使用注意事项Installation, use precautions
1、气动隔膜阀应垂直安装于管道上,体积重量较大的以及使用在振动场合时应加支承和夹固。
2、气动隔膜阀一般应设有旁通管路,以便在隔膜发生故障或维修时能转换成旁路操作,使生产过程正常进行,在一般不重要场合,装设手轮机构后可以省略旁通管路,以进行手动操作,同时可限制阀门开度,当手轮机构停止使用时,应恢复到原空档位置,以利于自控系统的正常进行。
3、清洗管道时,调节应处于*大开度,以便排除管道内污物。
4、如阀体衬有防腐层,安装在管道上时,应采用耐腐蚀软垫,并注意不使阀体法兰密封面受损。
5、对隔膜及衬里应定期检查,防止因腐蚀和破裂而损坏其它零件和造成事故。

1, pneumatic diaphragm valves should be installed vertically in the pipe, the volume and the use of larger weight should be added where the vibration support and clamping.
2, pneumatic diaphragm should generally be equipped with bypass piping, so that the diaphragm failure or maintenance can be converted into bypass operation, the normal production process, in general, important occasions, installation of hand wheel can be omitted after the next through the pipeline, for manual operation, and limits the valve opening, when the hand wheel to stop the use, should be restored to the original neutral position to facilitate the automatic control system normally.
3, cleaning pipes, adjust the maximum opening to be in order to rule out the dirt inside the pipe.
4, a coating, such as body lining, installed in the pipe should be corrosion-resistant cushion, and pay attention not to damage the valve body flange sealing surface.
5, the diaphragm and the lining should be checked regularly to prevent rupture due to corrosion and damage other components and cause an accident.
