Çift Offsetli Kelebek Vanalar

Çift offsetli kelebek vanalar şaftı hem eksenden hem sedir düzleminden kaydırır; disk açılışta neredeyse hemen sedirden kalkar ve sürtünme aşınması konsantrik tasarıma göre belirgin biçimde azalır. Aralık, PN10 ila PN63 / Class 150 ila Class 1500'de DN50 ila DN600'ü wafer ağızlı; sfero döküm, WCB veya SS304/SS316 gövde, alüminyum bronza kadar uyumlu disk seçenekleri, SS410 serisi miller, paslanmaz-artı-grafit sızdırmazlık üzerinde 13Cr'dan kobalt-krom sert kaplamaya gövde sedirleri ile redüktörlü veya aktüatörlü çalışır. Tasarım API 609 / DIN 2559 / EN 593'ü izler; ASME B16.5 / DIN3202 F4 / EN558-1 yüzey-yüzey ve API 598 testi uygulanır. Seçim; ofsetli sedir tasarımına göre sınıfa, sıcaklığa göre sedir eşleşmesine ve eşleşen flanşlara göre wafer boyuna göre yapılır.

Sipariş ve dokümantasyon

Dokümanlar

İhtiyacınız olan dokümantasyon setini talep ile birlikte isteyin — bu icra için tipik kalemler (malzeme sertifikaları, listelenen denetim standardına uygun test raporları, boyut çizimleri) teklifte teyit edilir ve onunla birlikte tedarik edilir.

Teklif

Teklife hazır bir talep şunları belirtir: nominal boyut ve basınç sınıfı, gövde ve yatak malzemesi tercihi, uç bağlantısı, tahrik ve sıcaklıkla birlikte görev ortamı. Bu sayfadaki tipik değerler kıyaslama referans aralıklarıdır; bağlayıcı değerler teklifte teyit edilir.

Numune ve tedarik

Tedarik şartları, sipariş adetleri ve teslim süresi sipariş başına kararlaştırılır — talep ile birlikte varış ülkesini ve gerekli takvimi belirtin.

Depolama ve sevkiyat

Vanaları yatakları ve sızdırmazlık elemanları UV, ozon ve deformasyondan korunacak şekilde depolayın, uç yüzey koruyucularını montaja kadar takılı tutun; elastomer veya PTFE yataklı icralarda uzun süreli açık alanda depolamadan kaçının — yatak bileşikleri doğrudan güneş ışığında ve don koşullarında en hızlı yaşlanır.
