概述Outline
QZMAT氣動薄膜隔膜調節閥\QZMBT氣動薄膜隔膜調節閥由多彈簧氣動薄膜執行機構和隔膜閥組成。隔膜閥體流通平滑、節流元件為彈性隔膜閥，閥蓋上無填料函。因而閥流通能力比一般調節閥大且無泄漏，在許用壓差范圍內可作切斷閥用。氣開、氣關作用由正反執行機構實現。 該閥適用于高粘性流體、懸浮狀顆粒、纖維介質和有毒介質、腐蝕性介質的調節場合。

QZMAT pneumatic diaphragm valve film \ QZMBT diaphragm valve pneumatic membrane pneumatic membrane by the multi-spring diaphragm actuators and 免費信息ponents. Diaphragm valve body flow smoothly, cutting 免費信息ponents 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.

安裝、使用注意事項Installation, use precautions
1、氣動隔膜閥應垂直安裝于管道上，體積重量較大的以及使用在振動場合時應加支承和夾固。
2、氣動隔膜閥一般應設有旁通管路，以便在隔膜發生故障或維修時能轉換成旁路操作，使生產過程正常進行，在一般不重要場合，裝設手輪機構后可以省略旁通管路，以進行手動操作，同時可限制閥門開度，當手輪機構停止使用時，應恢復到原空檔位置，以利于自控系統的正常進行。
3、清洗管道時，調節應處于最大開度，以便排除管道內污物。
4、如閥體襯有防腐層，安裝在管道上時，應采用耐腐蝕軟墊，并注意不使閥體法蘭密封面受損。
5、對隔膜及襯里應定期檢查，防止因腐蝕和破裂而損壞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 免費信息ponents and cause an accident.
