What Is a Breather Valve?

A breather valve(pressure/vacuum relief valve) is designed to protect storage tanks, process systems, and equipment from excessive pressure and vacuum conditions. These valves allow for the controlled venting of gases or vapors and help to maintain a safe working environment by preventing tank damage and minimizing product loss due to evaporation​​​​.

Bagaimana Injap Nafas Berfungsi?

Injap pernafasan berfungsi dengan menggunakan palet beban berat atau spring untuk mengawal aliran melalui injap. Apabila tekanan dalaman atau vakum mencapai titik set, palet terangkat dari tempat duduk untuk membenarkan aliran. Ini menghalang kehilangan pelepasan sehingga sangat dekat dengan tekanan yang ditetapkan dan menghalang pengambilan udara sehingga sangat dekat dengan vakum yang ditetapkan.

What Are The Benefits of Using Breather Valve?

  1. High flow capacity from a compact valve size.
  2. Wide range of pressure and vacuum settings for maximum tank protection.
  3. Minimization of gas loss and evaporation, resulting in economic savings.
  4. Compliance with stringent emission control regulations.
  5. Modular design allows for customization to specific requirements​​​​.

What Materials Are Breather Valves Made From?

Breather valves can be constructed from various materials, including aluminum, stainless steel, carbon steel, ductile iron, and alloys such as C276. The choice of material depends on the specific application and the type of media being handled​​​.

What Are Common Applications of Breather Valves?

Common applications include protecting storage tanks in industries such as pharmaceuticals, food and beverage, chemical processing, and petrochemical industries. They are also used in systems where vapors need to be piped away or vented to the atmosphere​​​.

Apakah Piawaian yang Dipatuhi oleh Injap Pernafasan?

Injap pernafasan direka bentuk dan diuji mengikut piawaian seperti API 2000:2014 dan EN ISO 28300:2016. Mereka juga memenuhi Arahan Eropah 2014/34/EU untuk peralatan yang digunakan dalam atmosfera yang berpotensi meletup (ATEX)​​​​.

How Do I Select the Right Breather Valve For My Application?

Selecting the right breather valve involves considering factors such as tank size, media characteristics (flash point, boiling point, latent heat of vaporization, molecular mass), location, maximum filling and emptying rates, and the required set pressure and vacuum settings. Consulting with a Yee Valve expert and using a valve sizing service can help ensure optimal performance and cost-effectiveness​​​​.

Apakah Penyelenggaraan yang Diperlukan untuk Injap Nafas?

Pemeriksaan dan penyelenggaraan yang kerap adalah perlu untuk memastikan injap pernafasan beroperasi dengan betul. Ini termasuk memeriksa sebarang sekatan, memastikan palet dan tempat duduk bersih dan bebas daripada serpihan, dan mengesahkan bahawa tekanan dan vakum yang ditetapkan adalah tepat. Prosedur penyelenggaraan hendaklah mengikut saranan pengilang untuk mengekalkan keselamatan dan kecekapan​​​.

What Is a Flame Arrester?

A flame arrester is a safety device installed in equipment that contains flammable gases or vapors. It prevents the propagation of flames and explosions by quenching the flame front before it can reach the protected side of the device.

How Do Flame Arresters Work?

Flame arresters function by cooling the flame front through a series of narrow passages or “quenching gaps.” These gaps are designed to be small enough to extinguish the flame while allowing gases to pass through.

What Are the Different Types of Flame Arresters?

  • Deflagration Flame Arresters: Protect against explosions where the flame propagates at subsonic velocities.
  • Detonation Flame Arresters: Designed for more severe conditions where the flame front travels at supersonic speeds, producing shock waves.
  • End-of-Line Flame Arresters: Installed at the end of a pipeline to protect against external sources of ignition.
  • In-Line Flame Arresters: Installed within the pipeline to prevent the spread of flames within the piping system.

Where Are Flame Arresters Typically Used?

Flame arresters are commonly used in systems for generating, storing, and transporting flammable gases and liquids, such as chemical processing plants, oil refineries, gas storage facilities, and pipelines.

What Maintenance Is Required for Flame Arresters?

Regular inspection and maintenance are essential for flame arresters to function correctly. Key maintenance tasks include:

  • Initial inspection three months after commissioning.
  • Annual inspections as a minimum for clean processes.
  • Additional inspections if an explosion is detected or if there are signs of damage or corrosion.
  • Cleaning to remove debris, insects, or corrosion that can block the quenching elements​​​​.

What Should Be Checked During Flame Arrester Maintenance?

  • Ensure the flame arrester is correctly installed according to the operating conditions.
  • Verify that no unauthorized modifications have been made.
  • Check for blockages, corrosion, and mechanical damage.
  • Confirm that all fasteners are secure and tightened to the required torque.
  • Record all maintenance activities accurately.

What Are The Consequences of Poor Maintenance?

Poorly maintained flame arresters can fail to provide adequate protection against explosions, potentially leading to catastrophic equipment damage and safety hazards. Common issues include blocked elements, severe corrosion, and mechanical damage, which can impair the flame arrester’s effectiveness​​​​​​.

Bolehkah Penangkap Api Digunakan dalam Mana-mana Jenis Sistem Paip?

Flame arresters must be used under the specific conditions they were designed and tested for. They are available in various configurations to suit different piping systems, and the correct model should be selected based on the type of gas, operating pressure, and temperature range​​​.

Apakah Pertimbangan Utama Semasa Memasang Penangkap Api?

  • Pastikan keserasian dengan keadaan proses, termasuk jenis gas dan tekanan.
  • Ikuti garis panduan tork untuk sambungan bebibir.
  • Letakkan penangkap api dengan betul untuk memudahkan penyelenggaraan masa hadapan.
  • Periksa kebocoran selepas pemasangan untuk memastikan pengedap yang betul.

Adakah Terdapat Sebarang Amaran Khusus Untuk Mengendalikan Penangkap Api?

  • Do not use lifting eyebolts to lift the entire flame arrester assembly; they are only for handling the housing during inspection and maintenance.
  • Avoid piping drainage, instrumentation, and cleanout connections to a common line to prevent flame bypass.
  • Replace damaged flame elements immediately as they can render the flame arrester ineffective​​​​.

What Are Your Payment Terms?

  • Pay 30% in advance and 70% before shipment by T.T. (Standard Products)
  • Pay 100% in advance by T.T. (Special Products)
  • 100% L/C at sight from special customers and L/C should be issued from the world’s first-class bank. (Special Markets)
