生物安全密閉閥
密閉閥 / 氣密閥也稱低泄漏閥，生物密閉閥， 可以將通風(fēng)系統(tǒng)分隔為幾個(gè)分區(qū)，應(yīng)用于核電、藥廠、石化、食品化工、實(shí)驗(yàn)室等場所。 具有良好的氣密性，可以滿足特殊場合下零匯漏的安全（在指定壓差下，達(dá)到零泄露）密閉閥/氣密閥在典型應(yīng)用：在BIBO系統(tǒng)中隔離過濾器和受污染的部件。
其主要特點(diǎn)包括：
1. 氣流控制：用于送風(fēng)和排風(fēng)管道，能夠在更換過濾器或維護(hù)設(shè)備時(shí)有效阻斷氣流，防止污染物擴(kuò)散 。
2. 隔離防護(hù)：將通風(fēng)系統(tǒng)分隔為多個(gè)分區(qū)，實(shí)現(xiàn)氣密性隔離，滿足零泄漏的安全要求 。
3. 系統(tǒng)配套：通常與送、排氣裝置以及高效排風(fēng)口等配套使用，確保通風(fēng)系統(tǒng)的正常運(yùn)行和安全性 。
4. 定制性：閥體的材料和尺寸可以根據(jù)客戶的實(shí)際需求定制 。
5. 良好的氣密性：采用高質(zhì)量的硅膠密封墊和整體滿焊加工工藝，在指定壓差下達(dá)到零泄漏 。
6. 耐用性：閥片開關(guān)操作次數(shù)可達(dá)5000次以上，仍保持良好的氣密性 。
7. 自動(dòng)化控制：電動(dòng)密閉閥可以與自控系統(tǒng)配套，實(shí)現(xiàn)自動(dòng)控制調(diào)節(jié)風(fēng)量，即使在斷電情況下也能保持氣密性 。
8. 安全性：在更換過濾器或維護(hù)設(shè)備時(shí)，能夠阻斷單個(gè)裝置的氣流，保證實(shí)驗(yàn)室內(nèi)的氣流穩(wěn)定和正常運(yùn)行 。
此外，生物安全氣密閥的閥體材料和尺寸可以根據(jù)客戶需求定制，以滿足不同場所和設(shè)備的特殊要求。電動(dòng)密閉閥可以與自控系統(tǒng)配套，實(shí)現(xiàn)自動(dòng)控制調(diào)節(jié)風(fēng)量，即使在斷電的情況下也可以保證其氣密性 。密閉閥在初始?jí)毫χ挡恍∮?/span>-2.5kPa和+2.5kPa兩種狀態(tài)下測試，小時(shí)泄漏率不超過測試容積的0.25%，分鐘泄漏率不超過測試容積的0.1%，且在閥片開、關(guān)操作5000次以后以及經(jīng)過氧化氫熏蒸40小時(shí)后依據(jù)標(biāo)準(zhǔn)測試氣密性，泄漏率均滿足要求 。
Biosafety valve
Main Features of Biological Safety Air-tight Valves
1. Airflow Control: Used in supply and exhaust air ducts, effectively blocking airflow when replacing filters or maintaining equipment to prevent the spread of contaminants.
2. Isolation Protection: Divides the ventilation system into multiple compartments, achieving airtight isolation to meet the safety requirements of zero leakage.
3. System Compatibility: Typically used in conjunction with supply and exhaust devices, as well as high-efficiency exhaust air outlets, to ensure the normal operation and safety of the ventilation system.
4. Customizability: The material and size of the valve body can be customized according to the actual needs of the customer.
5. Good Airtightness: Equipped with high-quality silicone sealing pads and full-welding processing technology, achieving zero leakage at the specified pressure difference.
6. Durability: The valve flap can operate more than 5,000 times while still maintaining good airtightness.
7. Automated Control: Electric air-tight valves can be matched with automatic control systems to adjust air volume automatically, ensuring airtightness even in the event of a power outage.
8. Safety: When replacing filters or maintaining equipment, it can block the airflow of individual devices, ensuring stable airflow and normal operation within the laboratory.
Typical
Applications
-
BIBO Systems: Isolating filters and contaminated parts in biological isolation
systems.
- Nuclear Power Plants, Pharmaceutical Factories, Petrochemical, Food Chemical, and Laboratories: Used in the ventilation systems of these places to ensure airtightness and safety.
Technical Parameters
-
Airtightness Test: Tested under initial pressure values of no less than -2.5kPa
and +2.5kPa, the hourly leakage rate does not exceed 0.25% of the test volume,
and the minute leakage rate does not exceed 0.1% of the test volume.
- Durability Test: After 5,000 operations of the valve flap opening and closing, and after 40 hours of formaldehyde fumigation, the leakage rate meets the requirements.
These features and applications make biological safety air-tight valves indispensable in places that require high airtightness and safety.
