Application-Specific Recommendations

FAQ

1. What is the most overlooked parameter in butterfly valve selection?

Flow velocity. Many engineers focus only on pressure and temperature while ignoring pipe flow velocity. Excessive velocity causes vibration and noise, accelerating seat wear, while too-low velocity prevents full disc opening, haifar da zance. Ka'idar babban yatsa: kiyaye saurin ƙasa 10 fps (3 m/s), tare da 7 fps (2.1 m/s) a matsayin manufa mafi aminci.

2. Shin in yi girma ko rage girman bawul ɗin?

Haka kuma. Yin yawa yana hana cikakken buɗe diski, haifar da zance da gazawar da wuri. Ƙarƙashin ƙima yana haifar da raguwar matsa lamba da yawa kuma yana zubar da kuzari. Madaidaicin hanya shine ƙima bisa ainihin yanayin kwarara, ba kawai girman bututu ba. Tuntuɓi mai ƙira mai ƙira (Cv) alluna don dacewa da ainihin buƙatun kwarara.

3. Yaushe bawul ɗin malam buɗe ido zai iya maye gurbin bawul ɗin malam buɗe ido?

A lug bawul iya maye gurbin flanged bawul lokacin: matsa lamba aiki ≤150LB (Class 150), girman bututu ≤24 inci, Ana buƙatar sabis na ƙarshe, kuma kasafin kudin yana da iyaka. Don matsa lamba (≥ Darasi 300) ko babban diamita (≥36 inci) aikace-aikace, flanged bawuloli sun kasance mafi aminci zaɓi.

4. Wanne shugabanci yakamata diski ya fuskance lokacin shigar da bawul ɗin malam buɗe ido?

Ana iya shigar da bawul ɗin malam buɗe ido a kowane kusurwa, amma mafi kyawun aikin masana'antu shine shigarwa na diski a kwance (shaft a kwance, diski yana rataye a tsaye lokacin buɗewa). Wannan yana rage zubewar barbashi a cikin ɓangarorin tushe, mika rayuwar sabis. Shigarwa a tsaye (shaft a tsaye) sanya diski a kwance, yana sa ya fi saurin tara tarkace.

5. Ta yaya zan san lokacin da wurin zama na bawul yana buƙatar sauyawa?

Alamu uku: Na farko, yabo mai gani bayan rufewa (wurin zama mai laushi tare da ci gaba da digo). Na biyu, ƙara ƙarfin ƙarfin aiki sosai (wurin zama tsufa da tsayawa).
