DBB (bloking blok lan getar) Ball Valve nawakake dual mati, pamisahan dual, lan fungsi getihi. It is ideal for use with various pipelines that carry aviation kerosene, light oil, natural gas, liquefied gas, pipeline gas, and chemical media, serving as an optimal solution for controlling media flow.

The core working principle of the DBB ball valve lies in the operation of two sealing slides installed on the plug. This valve optionally incorporates an automatic relief device. Once the valve is fully closed, this device helps prevent any abnormal pressure increase within the valve chamber, ensuring the valve’s effective functioning.

Moreover, the valve features a switch indicator that synchronizes with the switch position, offering an accurate display of the valve’s operational status. This feature enhances usability and allows for precise valve control.

Fitur saka katup bola DBB

1. Gesekan minimal lan nyandhang: During the valve’s opening and closing process, the valve body’s sealing surface does not come into contact with the sliding plate’s sealing surface. This absence of contact prevents friction and wear, extending the valve’s service life and reducing the opening and closing torque.
2. Pangopènan sing trep: The DBB ball valve’s design allows for easy maintenance. There is no need to remove the valve from the pipeline for servicing; one only needs to disassemble the valve bottom cover and replace a pair of slides.
3. Pengurangan biaya: Diameter suda awak katup lan plug concubus kanggo tabungan biaya.
4. Area Sealing Truthable lan Smooth: The inner cavity of the valve body is plated with hard chromium, resulting in a complex and smooth sealing area that enhances the valve’s durability and performance.

Ngerti DBB lan Dib: Definisi lan tes

Katup DBB (getar)) nampilake rong kursi sing disegel lan piranti sing disusupi ing kamar tengah. Nalika katup ditutup lan piranti sing disusupi dibukak, loro-lorone katup wis ditekan bebarengan. Kursi katup sealing bisa ngalangi tekanan ing loro ujung katup.

Kanggo ketemu definisi DBB, katup kudu duwe rong kahanan lan siji fungsi:

• Kondisi 1: Katup kasebut kudu duwe loro kursi sing disegel.
• Kondisi 2: The valve’s middle chamber must include a discharge device (for venting, blowdown, etc.).
• Fungsi: Nalika piranti sing disusupi ing kamar tengah dibukak, loro-lorone katup wis diresisi, lan kursi katup sing bisa diblokir bisa ngalangi tekanan ing pungkasan.

Testing a DBB valve involves the following steps as specified in Appendix H₉ of API 6D 24:

1. Miwiti karo katup setengah mbukak lan isi ruangan katup lan katup kanthi medium uji (biasane banyu seger).
2. Nutup katup lan mbukak piranti sing disusupi ing rongga katup, saéngga medium uji luwih gedhe saka port sing disusupi.
3. Pressurize both ends of the valve until the pressure reaches 1.1 times the rated pressure of the valve shell material at 38°C.
4. Priksa bocor leakage liwat plabuhan sing diselehake ing rongga katup. Kriteria ditampa kanggo segel sing alus yaiku bocor nol, dene kanggo segel sing angel, bocor ora kudu ngluwihi kelas d minangka saben Iso5208.

Elinga yen kursi katup DBB ora duwe fungsi isolasi. Kosok baline, DIB (allves kaping pindho (getar) ing rong jinis: DIB-1 lan DIB-2.

The DIB-1 valve requires an external automatic safety relief valve, as its seat cannot automatically relieve pressure. If pressure builds up in the valve chamber, the valve might explode. The relief pressure of the external relief valve should be between 1.1 and 1.33 times the rated pressure of the valve shell material at 38°C, and the reset pressure should not be less than 1.05 times.

Valve Dib duwe kursi loro sing disegel. Yen katup ditutup lan piranti sing dibubarake dibukak, siji mburi katup wis ditetepake, lan kursi katup sing bisa diasingake.

Ing kasus katup Dib-1, kursi seger duwe fungsi ngisolasi. Kanggo katup Dib-2, siji kursi duwe fungsi pamblokiran, lan liyane duwe fungsi isolasi (umume, kursi fungsi pemblokiran disetel ing mburi lumayan katup).

Kanggo ketemu definisi Dib, katup kudu duwe rong kahanan lan siji fungsi:

• Kondisi 1: Katup kasebut kudu duwe loro kursi sing disegel.
• Kondisi 2: The valve’s middle chamber must include a discharge device (for venting, blowdown, etc.).
• Fungsi: Nalika piranti sing disusupi ing rongga katup dibukak, siji mburi katup wis ditekan, lan kursi katup bisa ngisolasi tekanan ing siji mburi.

Kesimpulan

Kesimpulane, blok lan getih dobel (DBB) nyawiji peran kritis ing macem-macem industri, nyedhiyakake kontrol optimal liwat aliran media sing beda ing pipa. Fitur unik, kayata gesekan minimal lan nyandhang, perawatan sing trep, efektifitas biaya, lan area panyusun sing tahan lama, lancar, kanthi signifikan ningkatake efisiensi operasional.

Ngerti definisi, fungsi, lan test testing prosedur DBB lan dobel kaping pindho lan getar (Dib) Valves penting kanggo panggunaan lan panggunaan sing cocog. Katup kasebut, liwat prosedur tes sing ketat kaya sing digandhengake ing standar industri kaya API 6D 24, mesthekake linuwih, biaya instalasi sing suda, lan kerenangan sing kurang kanggo geter. Mangkono, ngrangkul teknologi kasebut nggawe industri kasebut kanggo nggayuh efisiensi operasional sing unggul.
