工作原理 　　

1.閥體和膜片的緊密配合提供閥體密封和閥座密封，確保管道內部和外部環(huán)境*隔絕，所以該閥門適用于無菌過程。 2.衛(wèi)生級氣動隔膜閥開啟和關閉是由閥桿的上下運動來實現(xiàn)。當閥桿處于上位時，球形膜片向上往下運動時帶動閥芯使膜片彎曲，被迫膜片緊貼閥座區(qū)域，關閉了管道流體通向路徑。 　　

3.該閥門可氣動操作，也可手動操作，還可以通過智能控制器控制。 ,　

閥門的構造 　　

1.無菌氣動隔膜閥*的密封結構，杜絕了衛(wèi)生死角，有利于介質自動排空和更利于CIP/SIP流程。 　　

2.無菌氣動隔膜閥根據(jù)其結構特點：建議15~30角度安裝（根據(jù)不同規(guī)格而定），有利于閥門清洗后*排泄，不易造成液體滯留閥門內部。 　　

3.閥體采用CNC精密加工，保證了閥腔的密封面與膜片孤度的吻合，減少了膜片的摩擦，延長其膜片的使用壽命。閥腔表面拋光可根據(jù)客戶要求進行機械或電解拋光，拋光度可達到0.25um。 　　

4.軟性彈性材料制成的隔膜對于那些被纖維團、固體顆粒、催化物等污染的工作介質不會產生敏感的反應，一般來說也不會因此影響到閥門的工作和密封。根據(jù)工作或消毒的溫度，以及工作介質的化學特性，可以選擇不同材料。 　　

5.由于不同工況下將選用不同類型的閥門和材質，在選擇閥體和隔膜以前，必須對一個產品的運用進行分析，尤其針對化學醫(yī)藥方面的運用，和高溫所導致的化學反應。通過有效的化學數(shù)據(jù)或專家認證，對材質的適宜性進行檢測。以此確保產品的使用安全性和長時間有效性。 　　

6.典型的隔膜固定方法為螺釘固定。與開孔固定形成對比，這種固定方式將受力面積分散至螺栓整個表面上，這是以防真空條件下，破壞隔膜的機械連接。

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.
