工作原理 　　

1.阀体和膜片的紧密配合提供阀体密封和阀座密封，确保管道内部和外部环境*隔绝，所以该阀门适用于无菌过程。 2.卫生级气动隔膜阀开启和关闭是由阀杆的上下运动来实现。当阀杆处于上位时，球形膜片向上往下运动时带动阀芯使膜片弯曲，被迫膜片紧贴阀座区域，关闭了管道流体通向路径。 　　

3.该阀门可气动操作，也可手动操作，还可以通过智能控制器控制。 ,　

阀门的构造 　　

1.无菌气动隔膜阀*的密封结构，杜绝了卫生死角，有利于介质自动排空和更利于CIP/SIP流程。 　　

2.无菌气动隔膜阀根据其结构特点：建议15~30角度安装（根据不同规格而定），有利于阀门清洗后*排泄，不易造成液体滞留阀门内部。 　　

3.阀体采用CNC精密加工，保证了阀腔的密封面与膜片孤度的吻合，减少了膜片的摩擦，延长其膜片的使用寿命。阀腔表面抛光可根据客户要求进行机械或电解抛光，抛光度可达到0.25um。 　　

4.软性弹性材料制成的隔膜对于那些被纤维团、固体颗粒、催化物等污染的工作介质不会产生敏感的反应，一般来说也不会因此影响到阀门的工作和密封。根据工作或消毒的温度，以及工作介质的化学特性，可以选择不同材料。 　　

5.由于不同工况下将选用不同类型的阀门和材质，在选择阀体和隔膜以前，必须对一个产品的运用进行分析，尤其针对化学医药方面的运用，和高温所导致的化学反应。通过有效的化学数据或专家认证，对材质的适宜性进行检测。以此确保产品的使用安全性和长时间有效性。 　　

6.典型的隔膜固定方法为螺钉固定。与开孔固定形成对比，这种固定方式将受力面积分散至螺栓整个表面上，这是以防真空条件下，破坏隔膜的机械连接。

Product Name: Pneumatic Diaphragm Valve, Stainless Steel Pneumatic Diaphragm Valve Manufacturer, Sanitary Pneumatic Diaphragm Valve Price;

Application: Products are widely used in clean pipeline systems such as pharmaceuticals, dairy products, food, wine, beverages, fine chemicals, etc.;

Material: stainless steel 316L material;

Specifications: ф19 - ф204;

Diaphragm: PTFE and EPDM double-layer diaphragm, food silicone two kinds of diaphragms are available for customers to choose according to their needs;

PTFE is commonly referred to as tetrafluoride material. This material has high temperature resistance, acid resistance, corrosion resistance and other functions. The temperature can be as high as 150° or even higher.

The temperature of food silica gel can generally only reach about 80°, and customers can choose the diaphragm suitable for their own use according to their requirements. Diaphragms conform to

FDA177.2600;

Inner surface: Ra0.6μm-0.4μm;

Outer surface: Ra0.6μm;

Handwheel: plastic handwheel;

Packing: first use shock-absorbing tape, externally use instant noodles, and finally use carton packaging, wrap with tape, seal tightly, and pack in chemical fiber bags; the long-distance outside is packed in wooden boxes, we ensure the safety of products during transportation sex.

working principle   

1. The tight fit of the valve body and the diaphragm provides valve body sealing and valve seat sealing to ensure complete isolation between the inside of the pipeline and the external environment, so the valve is suitable for aseptic processes. 2. The opening and closing of the sanitary pneumatic diaphragm valve is realized by the up and down movement of the valve stem. When the valve stem is in the upper position, when the spherical diaphragm moves up and down, it drives the valve core to bend the diaphragm, forcing the diaphragm to close to the valve seat area, closing the flow path of the pipeline.

3. The valve can be operated pneumatically or manually, and can also be controlled by an intelligent controller. 

The structure of the valve

1. The unique sealing structure of the aseptic pneumatic diaphragm valve eliminates the dead angle of hygiene, is conducive to the automatic emptying of the medium and is more conducive to the CIP/SIP process.

2. According to its structural characteristics, the sterile pneumatic diaphragm valve is recommended to be installed at an angle of 15~30 (depending on different specifications), which is conducive to the complete discharge of the valve after cleaning, and is not easy to cause liquid to remain inside the valve.

3. The valve body is precision machined by CNC, which ensures that the sealing surface of the valve cavity matches the solitary degree of the diaphragm, reduces the friction of the diaphragm, and prolongs the service life of the diaphragm. The surface polishing of the valve cavity can be mechanically or electrolytically polished according to customer requirements, and the polishing degree can reach 0.25um.

4. The diaphragm made of soft elastic material will not react sensitively to the working medium polluted by fiber groups, solid particles, catalysts, etc., and generally speaking, it will not affect the work and sealing of the valve. Depending on the operating or sterilizing temperature, as well as the chemical properties of the working medium, different materials can be selected.

5. Since different types of valves and materials will be selected under different working conditions, before selecting the valve body and diaphragm, the application of a product must be analyzed, especially for the application of chemical medicine, and the chemical reaction caused by high temperature. Materials are tested for suitability by valid chemical data or expert certification. This ensures the safety and long-term effectiveness of the product.

6. The typical diaphragm fixation method is screw fixation. In contrast to open-hole fixing, this fixing method spreads the stressed area over the entire surface of the bolt, which prevents the mechanical connection of the diaphragm from being damaged under vacuum conditions.
