Chidule cha kusiyana pakati pa ma valve a globe, ma valve a mpira ndi ma valve a chipata

Tiyerekeze kuti pali chitoliro choperekera madzi chokhala ndi chivundikiro. Madzi amalowetsedwa kuchokera pansi pa chitolirocho n’kutuluka kupita pakamwa pa chitolirocho. Chivundikiro cha chitoliro chotulutsira madzi chimakhala chofanana ndi chotseka cha valavu yoyimitsa. Ngati mukweza chitolirocho mmwamba ndi dzanja lanu, madziwo adzatuluka. Phimbani chivundikiro cha chubu ndi dzanja lanu, ndipo madziwo adzasiya kusambira, zomwe ndizofanana ndi mfundo ya valavu yoyimitsa.

Makhalidwe a valavu ya globe:

Kapangidwe kosavuta, kolimba kwambiri, kupanga ndi kukonza kosavuta, kukana kukangana kwa madzi kwakukulu, kumatha kulamulira kuyenda kwa madzi; ikayikidwa, imakhala yotsika mkati ndi kunja kwambiri, yolunjika; imagwiritsidwa ntchito makamaka m'madzi otentha ndi ozizira komanso mapaipi a nthunzi amphamvu kwambiri, si yoyenera kuchotsa tinthu tating'onoting'ono ndi zosungunulira zokhuthala kwambiri.

Mfundo yogwirira ntchito ya valve ya mpira:

Vavu ya mpira ikazungulira madigiri 90, malo ozungulira ayenera kuonekera pamalo olowera ndi otulukira, motero kutseka vavu ndikuletsa kuyenda kwa solvent. Vavu ya mpira ikazungulira madigiri 90, kutsegula kwa mpira kuyenera kuonekera pamalo olowera ndi malo olumikizirana, zomwe zimapangitsa kuti isambire popanda kukana kuyenda.

Makhalidwe a valavu ya mpira:

Ma valve a mpira ndi osavuta kugwiritsa ntchito, achangu komanso opulumutsa ndalama. Nthawi zambiri, mumangofunika kutembenuza chogwirira cha valve madigiri 90. Kuphatikiza apo, ma valve a mpira angagwiritsidwe ntchito pamadzimadzi omwe si oyera kwenikweni (okhala ndi tinthu tolimba) chifukwa valavu yake yooneka ngati mpira imasintha madziwo akamatsegula ndi kutseka.

Mfundo yogwirira ntchito ya valavu ya chipata:

Valavu ya chipata, yomwe imatchedwanso valavu ya chipata, ndi valavu yomwe imagwiritsidwa ntchito kwambiri. Mfundo yake yogwirira ntchito yotseka ndi yakuti pamwamba pa chipata chotseka ndi pamwamba pa mpando wa valavu zimakhala zosalala kwambiri, zathyathyathya komanso zogwirizana, ndipo zimagwirizana kuti ziletse kuyenda kwa madzi apakati, ndikuwonjezera magwiridwe antchito otseka pogwiritsa ntchito kasupe kapena chitsanzo chenicheni cha mbale ya chipata. Valavu ya chipata makamaka imagwira ntchito yodula kuyenda kwa madzi mupaipi.

Makhalidwe a valve ya chipata:

Kugwira ntchito kotseka ndikwabwino kuposa kwa valavu yoyimitsa, kukana kwa kupsinjika kwa madzi ndi kochepa, kutsegula ndi kutseka sikovuta kwenikweni, pamwamba pa kutseka sipawonongeka kwambiri ndi chosungunulira chikatsegulidwa kwathunthu, ndipo sichimalepheretsedwa ndi njira yoyendera zinthu. Ili ndi njira ziwiri zoyendera, kutalika kochepa kwa kapangidwe kake, ndi minda yayikulu yogwiritsira ntchito. Kukula kwake ndi kwakukulu, malo ena amafunika kuti agwire ntchito, ndipo nthawi yotsegulira ndi kutseka ndi yayitali. Malo otsekera amawonongeka mosavuta ndikukanda panthawi yotsegula ndi kutseka. Mawiri awiri otsekera amayambitsa mavuto pakupanga, kukonza ndi kukonza.

Chidule cha kusiyana pakati pa ma valve a globe, ma valve a mpira ndi ma valve a chipata:

Ma valve a mpira ndi ma valve a chipata nthawi zambiri amagwiritsidwa ntchito powongolera kuyatsa/kutseka ndi kudula madzi, koma nthawi zambiri sangagwiritsidwe ntchito kusintha kayendedwe ka madzi. Kuwonjezera pa kuwongolera kuyatsa/kutseka ndi kudula madzi, ma valve oletsa angagwiritsidwenso ntchito kusintha kayendedwe ka madzi. Mukafunika kusintha kuchuluka kwa madzi, ndi bwino kugwiritsa ntchito valavu yoyimitsa kumbuyo kwa mita. Pakugwiritsa ntchito kusintha kwa magetsi ndi kudula madzi, ma valve a chipata amagwiritsidwa ntchito chifukwa cha ndalama. Ma valve a chipata ndi otsika mtengo kwambiri. Kapena gwiritsani ntchito ma valve a chipata pa mapaipi akuluakulu, mafuta otsika mphamvu, nthunzi, ndi madzi. Poganizira kulimba, ma valve a mpira amagwiritsidwa ntchito. Ma valve a mpira angagwiritsidwe ntchito m'malo ogwirira ntchito okhala ndi miyezo yapamwamba yotayikira madzi, ndi oyenera kuyambika mwachangu ndi kutseka, ndipo ali ndi magwiridwe antchito abwino komanso moyo wautali kuposa ma valve a chipata.
