Zaɓi Madaidaitan Kayan Wuta na Wuta Mai laushi
Ana amfani da hatimin ƙwallon ƙwallon ƙafa a masana'antu daban-daban. A matsayin madaidaicin matsi na matsi da sarrafa kwarara, aikin su mai santsi kuma abin dogaro yana da mahimmanci - wanda shine dalilin da ya sa kayan polymer ke aiki da kyau don kujerun bawul ɗin ball.
Bawul ɗin ƙwallon ƙafa suna da mahimmanci don ƙyale yanke ko wuce kwarara da matsa lamba na tsarin bututu. Haka kuma, ana amfani da su a cikin masana'antu irin su petrochemical da magunguna inda yoyo zai iya wakiltar mummunan sakamako ga muhalli ko samfurin kanta. Don haka, kujerar bawul ɗin ƙwallon yana da mahimmanci a irin waɗannan yanayi tunda ita ce ke da alhakin rufe ruwan da ke ciki da kuma rarraba matsalolin wurin zama daidai.
Zaɓi kayan wurin zama na ƙwallon ƙwallon da ya dace yana da mahimmanci don tabbatar da aikin bawul ɗin da amincin samfurin da muhalli. Mafi na kowa ball bawul wurin zama kayan sun hada da PTFE,TFM, cika PTFE, PCTFE, PEEK, da POM.
MUHIMMANCIN ARZIKI NA KAYAN BALLVALVE SEAT
Lokacin zabar kayan polymer don wurin zama na bawul, akwai abubuwa da yawa waɗanda ke da hannu. Maɓalli na kayan aiki sun haɗa da…
● Isasshen ductility don samar da hatimin abin dogaro
● Kwanciyar kwanciyar hankali don tabbatar da wurin zama na ƙwallon ƙwallon yana riƙe da siffarsa don amintaccen hatimi da aiki
● Ƙunƙarar juzu'i don kiyaye ƙarar ƙara a ƙaranci
● Ƙananan ƙayyadaddun ƙayyadaddun haɓakawar thermal don haka wurin zama na ball bawul ya riƙe siffar sa lokacin da canjin yanayi ya faru
● Kyakkyawan juriya na lalacewa don tsawon rayuwar sabis
