Lokacin da ruwan ya sami isasshen matsi, yana buɗe bawul; lokacin da ya dawo (juyawar baya) a matsa lamba na ƙira, yana rufe bawul - yana hana kwararar da ba a so.
● KWALLON BALL: Bawul ɗin ball shine bawul ɗin juyi kwata da ake amfani da shi don aikace-aikacen kashewa. Bawul ɗin yana buɗewa kuma yana rufe magudanar ruwan ta hanyar ƙwallon da aka gina, wanda ke juyawa cikin jikin bawul ɗin. Bawul ɗin ƙwallon ƙafa misali ne na masana'antu don aikace-aikacen kashewa kuma sun fi sauƙi kuma mafi ƙanƙanta fiye da bawul ɗin ƙofar, waɗanda ke yin irin wannan manufa. Babban zane-zane guda biyu suna iyo da trunnion (gefe ko babban shigarwa)
BUTTERFLY VALVE: Wannan madaidaici ne, mai tsada, bawul don daidaitawa ko buɗewa / rufe magudanar ruwan. Ana samun bawul ɗin malam buɗe ido a cikin ƙira mai ƙima ko ƙira (biyu / sau uku), suna da ƙayyadaddun tsari kuma suna ƙara yin gasa vs. ball bawul, saboda sauƙin gini da farashi.
● PINCH VALVE: Wannan nau'in bawul ɗin motsi ne na linzamin kwamfuta wanda za'a iya amfani dashi don maƙasasshe da aikace-aikacen rufewa a aikace-aikacen bututu waɗanda ke ɗaukar kayan aiki mai ƙarfi, slurries da ruwa mai yawa. Bawul ɗin tsunkule yana da bututu mai tsunkule don daidaita kwararar.
KYAUTA PLUG: Ana rarraba bawul ɗin toshe azaman bawul mai juyi kwata don aikace-aikacen kashewa. Romawa ne suka gabatar da bawul na farko don sarrafa bututun ruwa.
● KWALLON TSIRA: Ana amfani da bawul ɗin aminci don kare tsarin bututu daga matsi mai haɗari wanda zai iya yin barazana ga rayuwar ɗan adam ko wasu kadarori. Ainihin, bawul ɗin aminci yana sakin matsa lamba yayin da aka ƙetare ƙimar saiti.
KYAUTA KWAKWALWA: Waɗannan bawuloli ne don sarrafa hadaddun hanyoyin sarrafa sinadarin petrochemical.
Y-STRAINERS: yayin da ba bawul ɗin da ya dace ba, Y-strainers suna da muhimmin aikin tace tarkace da kuma kare kayan aiki na ƙasa waɗanda za su iya lalacewa.
