Valve ndi gawo lowongolera la njira yoperekera madzimadzi, yokhala ndi kudula, kuwongolera, kupatutsidwa, kupewa kuthamangitsidwa, kuwongolera kupanikizika, shunt kapena kusefukira kwamphamvu yopumira ndi ntchito zina.Kugawika kwa ntchito ndi kugwiritsa ntchito kuli motere:
1.Truncation valve: valve truncation imadziwikanso kuti valve yotsekedwa, ntchito yake ndi kulumikiza kapena kuchepetsa sing'anga yamapaipi.Zomwe zimaphatikizapo mavavu a zipata, ma valve a globe, mavavu a pulagi, ma valve a mpira, ma valve a butterfly ndi ma diaphragm, ndi zina zotero.
2.Check valve: Valavu yowunikira imadziwikanso kuti njira imodzi kapena yosabwerera.Ntchito yake ndikuletsa payipi yapakati kubwerera kumbuyo.
3. Valve yachitetezo: Ntchito ya valve yotetezera ndikuletsa kuthamanga kwapakatikati mu payipi kapena chipangizo kuti zisapitirire mtengo wotchulidwa, kuti akwaniritse cholinga cha chitetezo.
4.Kuwongolera valve: kuphatikizapo valavu yoyendetsa, valavu yowonongeka ndi valve yochepetsera kuthamanga, ntchito yake · ndikusintha kupanikizika kwapakati, kutuluka ndi zina.
5.Shunt valve: imaphatikizapo ma valve osiyanasiyana ogawa ndi misampha, etc., ntchito yake ndi kugawa, kupatukana kapena kusakaniza sing'anga mu payipi.
Pamene valavu ntchito mu mzere madzi, amene udindo kusankha mtundu wa vavu, zambiri motsatira mfundo zotsatirazi:
1. Pamene kukula kwa chitoliro sikuposa 50mm, valavu yapadziko lonse iyenera kugwiritsidwa ntchito, ndipo pamene chitoliro cha chitoliro ndi chachikulu kuposa 50mm, valavu yachipata ndi valavu ya butterfly iyenera kugwiritsidwa ntchito.
2.Pamene otaya ndi osindikizira madzi ayenera kusinthidwa, valavu yoyendetsera, globe iyenera kugwiritsidwa ntchito.
3. Ngati kukana kwa madzi kumayenda pang'ono (monga chitoliro chothira pampu yamadzi), valve yachipata iyenera kugwiritsidwa ntchito
4. Vavu yachipata ndi valavu ya butterfly iyenera kugwiritsidwa ntchito pagawo la chitoliro komwe madzi amayenera kuyenda pawiri, ndipo valavu ya globe sayenera kugwiritsidwa ntchito.
5. Vavu ya butterfly ndi valavu ya mpira iyenera kugwiritsidwa ntchito pazigawo zomwe zimakhala ndi malo ochepa oyikapo
6. mu gawo la chitoliro lomwe nthawi zambiri limatseguka komanso lotsekedwa, ndikofunikira kugwiritsa ntchito valavu ya globe
7.Multi-function valve iyenera kugwiritsidwa ntchito pa chitoliro chotulutsira madzi ndi m'mimba mwake
8.Check mavavu adzaikidwa pazigawo zotsatirazi za mapaipi:Papaipi yolowera ya chotenthetsera chamadzi chotsekedwa kapena zida zogwiritsira ntchito madzi;Chitoliro chotulutsira madzi; Pagawo la chitoliro chotulutsira madzi a thanki yamadzi, nsanja yamadzi ndi dziwe lokwera la chitoliro chomwecho.
Zindikirani: Sikoyenera kukhazikitsa ma valavu a cheki a magawo a mapaipi okhala ndi zoletsa kubwerera.
