Umutekano wo gutabara, bizwi kandi nkumutekano urengerwa na valve, nigikoresho cyogutabara cyikora gitwarwa numuvuduko wo hagati. Irashobora gukoreshwa nka valve yumutekano hamwe na valve yubutabazi bitewe na porogaramu.

Dufashe Ubuyapani nkurugero, haribisobanuro bike bisobanutse byumutekano wumutekano hamwe nubutabazi. Mubisanzwe, ibikoresho byumutekano bikoreshwa mubwato bunini bwo kubika ingufu nka boiler byitwa indangagaciro z'umutekano, naho ibyashyizwe kumiyoboro cyangwa ibindi bikoresho byitwa ubutabazi. Icyakora, ukurikije ibivugwa muri “Tekiniki ya tekiniki yo kubyara ingufu z'amashanyarazi” ya Minisiteri y’ubucuruzi n’inganda mpuzamahanga mu Buyapani, ibice byingenzi by’ubwishingizi bw’umutekano byerekana imikoreshereze y’imyanda y’umutekano, nka za bombo, superheater, reheater, nibindi. Mubihe aho uruhande rwo hasi rwumuvuduko rugabanya valve rugomba guhuzwa na boiler na turbine, hagomba gushyirwaho valve yubutabazi cyangwa valve yumutekano. Muri ubu buryo, valve yumutekano isaba kwizerwa kuruta valve yubutabazi.

Byongeye kandi, duhereye ku mategeko agenga imicungire ya gaze ya minisiteri y’umurimo y’Ubuyapani, amategeko ya minisiteri y’ubwikorezi n’amashyirahamwe y’ubwato mu nzego zose, kumenyekanisha n’amabwiriza y’amazi asohoka neza, twita valve yemeza ko isohoka ingano yumutekano wumutekano, hamwe na valve itemeza ubwinshi bwimyuka isohoka. Mubushinwa, bwaba bwarafunguwe cyangwa mikoro ifunguye, hamwe byitwa valve yumutekano.

1. Incamake

Ibyingenzi byumutekano nibikoresho byingenzi byumutekano kubiteka, imiyoboro yumuvuduko nibindi bikoresho byingutu. Ubwizerwe bwimikorere yabo nubwiza bwimikorere yabo bifitanye isano itaziguye numutekano wibikoresho nabakozi, kandi bifitanye isano rya hafi no kubungabunga ingufu no kurengera ibidukikije. Ariko, bamwe mubakoresha hamwe nishami rishushanya burigihe bahitamo icyitegererezo kitari cyo muguhitamo. Kubera iyo mpamvu, iyi ngingo irasesengura ihitamo ryumutekano.

2. Ibisobanuro

Ibyitwa umutekano wumutekano muri rusange harimo indangagaciro zubutabazi. Duhereye ku mategeko agenga imiyoborere, indiba zashyizwe mu buryo butaziguye ku byuka cyangwa ubwoko bwubwato bugomba kwemezwa nishami rishinzwe kugenzura tekinike. Mubisobanuro bigufi, byitwa indangagaciro z'umutekano, naho ubundi byitwa ubutabazi. Umutekano wumutekano hamwe nubutabazi burasa cyane muburyo n'imikorere. Byombi bihita bisohora imbere imbere mugihe umuvuduko wo gufungura urenze kugirango umutekano wibikoresho bibyara umusaruro. Bitewe nibi bintu byingenzi bisa, abantu bakunze kwitiranya byombi mugihe babikoresheje. Byongeye kandi, ibikoresho bimwe na bimwe bitanga umusaruro nabyo bivuga ko ubwoko ubwo aribwo bwose bushobora gutoranywa mu mategeko. Kubwibyo, itandukaniro ryombi ryirengagizwa. Kubera iyo mpamvu, ibibazo byinshi bivuka. Niba dushaka gutanga ibisobanuro bisobanutse byombi, turashobora kubyumva dukurikije ibisobanuro mugice cya mbere cya ASME Boiler na Pressure Vessel Code:

(1)Umuyoboro wumutekano, igikoresho cyogutabara cyikora gitwarwa numuvuduko uhagaze wikigereranyo imbere ya valve. Irangwa nigikorwa cyuzuye cyo gufungura hamwe no gufungura gitunguranye. Ikoreshwa muri gaze cyangwa ikoreshwa rya parike.

(2)Inkeragutabara. Ifungura ugereranije no kwiyongera k'umuvuduko urenze imbaraga zo gufungura. Ikoreshwa cyane mubikorwa byamazi.
