Fitur Utama DBB Valve:

1. Frictionless Sealing: The design of DBB valves ensures no contact between the sealing surfaces, resulting in minimal friction and wear. This not only extends the valve’s service life but also reduces the required opening and closing torque.

2. Pangopènan Sederhana: katup DBB ngidini pangopènan gampang tanpa perlu mbusak tutup saka pipa. Kanthi mung disassembling tutup ngisor tutup, sepasang piring ngusapake bisa diganti, streamlining tata cara pangopènan.

3. Cost-Effective Design: The reduced diameter of the valve body and cock contributes to cost savings without compromising performance. The valve body’s inner cavity is plated with hard chromium, providing a hard and smooth sealing area for enhanced durability.

4. Advanced Sealing Technology: Elastic seals on the slide are made of fluoro rubber and are molded into grooves on the slide’s surface. Metal-to-metal sealing with fireproof properties acts as a backing for the elastic sealing, ensuring reliable and secure sealing performance.

5. Piranti Relief Otomatis: Klep DBB bisa dilengkapi piranti relief otomatis opsional. Sawise tutup tutup rampung, fitur iki nyegah penumpukan tekanan sing ora normal ing kamar tutup, saéngga nambah safety. Uga nggampangake tes lan inspeksi katup.

6. Switch Indicator: DBB valves are equipped with a synchronized switch indicator, providing an accurate display of the valve’s switch state. This feature enables easy visual confirmation of the valve’s operational status.

Keuntungan saka DBB Valve:

Adoption katup DBB ngasilake akeh kaluwihan tinimbang konfigurasi katup konvensional. Kaping pisanan, katup DBB ngilangi kebutuhan kanggo macem-macem sambungan kanthi nggabungake insulasi dual ing katup siji. Iki nyebabake nyuda bobot sing signifikan, ngirit ruang, lan proses instalasi sing luwih ramping, sing nyebabake efisiensi wektu lan biaya. Kajaba iku, katup DBB kanthi efektif ngatasi masalah bocor sajrone operasi sistem, njamin lingkungan kontrol cairan sing dipercaya lan aman. Kemampuan kanggo nutup kanthi cepet lan gampang dibuwang nambah keluwesan operasional lan nyuda downtime.

Isolasi ganda, syarat penting ing tata cara pangopènan hilir katup isolasi pisanan, digayuh kanthi efisien liwat katup DBB. Venting rongga, sing difasilitasi dening katup ventilasi bal utawa globe, ngidini ventilasi tekanan kompres sing aman ing antarane rong katup isolasi. Kajaba iku, katup DBB wis nggedhekake fungsine kanggo kalebu injeksi kimia lan titik sampling, uga integrasi karo katup kontrol sing dibangun, nyedhiyakake solusi serbaguna kanggo macem-macem kabutuhan kontrol cairan.

Aplikasi DBB Valve:

Katup DBB nemokake panggunaan ekstensif ing macem-macem industri lan aplikasi. Ing industri gas alam, katup DBB nduwe peran penting ing proses transmisi, panyimpenan, lan industri. Dheweke uga akeh digunakake ing aplikasi petrokimia, njamin keamanan lan efisiensi sistem penanganan cairan. Ing saluran pipa Cairan lan saluran transmisi kanggo bahan olahan, katup DBB dadi katup utama lan multi-tujuan, nglindhungi saka bocor lan njaga integritas sistem. Kajaba iku, katup DBB penting banget ing aplikasi kalibrasi meter, ing ngendi pangukuran sing tepat lan akurat dadi penting.

Mbedakake katup DBB lan DIB:
While DBB valves offer protection against pressure from both sides of the valve, there is another variation known as Double Isolation & Block Valve (DIB valve). DIB valves provide an additional seal against pressure from only one side, making them suitable for applications requiring separate sealing of external pressure barriers. Operational safety standards and specific operational requirements dictate the selection of either DBB or DIB valves to ensure optimal performance and leakage tolerance.

Milih Katup DBB Tengen:

Milih katup DBB sing cocog kanggo aplikasi spesifik sampeyan mbutuhake sawetara faktor. Sifat aplikasi nduweni peran penting kanggo nemtokake jinis katup DBB sing dibutuhake. Jinis media sing dikontrol, kayata cairan kenthel utawa gas padhet, mengaruhi pilihan desain katup, apa iku bal full-bore, globe, utawa katup gerbang minangka katup blok lan katup jarum minangka katup getihen. Salajengipun, kahanan suhu lan tekanan nuntun pilihan katup DBB sing dirancang kanggo tahan operasi tekanan dhuwur lan suhu dhuwur. Katup bal anti-statis bisa digunakake kanggo nangani fluktuasi tekanan lan getaran ing operasi sensitif, njamin kontrol cairan sing aman lan dipercaya. Kosok baline, operasi tekanan rendah bisa nggunakake katup gerbang DBB siji kanthi wedges sing bisa diatur lan katup getihen awak.

Prinsip Kerja Katup DBB:

The key working principle of a DBB valve lies in the action of two sealing sliding plates installed on the valve cock. When the valve is closed, rotating the hand wheel causes the cock and sealing sliding plate to rotate by 90° and move downward. This motion pushes the sealing sliding plate against the inner cavity surface of the valve body, effectively forming a seal by evenly squeezing the elastic sealing ring at the upper and lower ends of the valve hole.

Conversely, when the valve is opened, rotating the hand wheel lifts the cock, retracting the sealing sliding plate from the valve body’s sealing surfaces. Once fully retracted and separated from the sealing surface, the hand wheel is further rotated by 90° to position the cock and sealing sliding plate, indicating that the valve is in the open position.

Kesimpulan:

Katup DBB wis muncul minangka solusi modern lan dipercaya kanggo aplikasi kontrol cairan sing mbutuhake isolasi ganda lan pencegahan bocor sing efektif. Desain sing kompak, fitur safety sing ditingkatake, lan keluwesan ing macem-macem industri nggawe pilihan sing cocog kanggo sistem kontrol cairan kritis. Kanthi milih katup DBB sing tepat adhedhasar syarat aplikasi, karakteristik media cairan, lan kahanan operasi, bisnis bisa njamin kinerja sing optimal, efisiensi sing luwih apik, lan nyuda risiko sing ana gandhengane karo bocor. Kanthi katup DBB, safety, linuwih, lan presisi bebarengan, nyedhiyakake kemampuan kontrol cairan sing ditingkatake kanggo macem-macem aplikasi industri.
