Valve: Chovala cha core

Mu dongosolo lovuta la mapaipi la mafakitale, mavuvu ali ngati njira yoyendetsera "mitsempha yamagazi", kuteteza madzi akachetechete. Chida chowoneka bwino kwambiri chomwe chizikhala chowoneka bwino kwambiri chimakhala cholumikizira mapaipi, zida, ndi njira, ndikupanga mwala wamafuta m'masewera amakono ndi mitundu yosiyanasiyana.

1, ntchito ndi gulu: Tsegulani zochitika zingapo

Cholinga cha zigwa cha mavuwa ndikukwaniritsa chiwongolero cholondola cha magawo monga oyenda / Off, kupanikizika, ma slor, etc.) pakutseka, kapena kusintha. Malinga ndi mawonekedwe a ntchito, banja lake limatha kutumizidwa m'mabuku angapo:

Dulani mtundu: monga mavesi achipapa, ndi mafavu adziko lapansi, kukula kwake, kuti akwaniritse zomata zam'tsogolo, zomwe nthawi zambiri zimagwiritsidwa ntchito pamawonekedwe am'mimba omwe amafunikira kudzipatula kwathunthu kwa sing'anga.

Kalasi yowongolera kapena mavalo a mpira ali ngati "owongolera oyendayenda" omwe amawongolera bwino kwambiri zamadzimadzi pang'ono pozungulira pa njira zamankhwala zomwe zimafunikira mtundu wa mankhwala omwe amafunikira kuwerengera kwa mankhwala.

Kalasi Yachitetezo: Mavavu otetezeka ali ngati okhulupirika "oyang'anira", amangotsegulira masisitilo atatha kukhala mtengo wovuta kwambiri, ndikupanga mzere wamphamvu wa zida monga mitsempha.

Gulu Lapadera: Ndi kapangidwe kake kanjira kanjira, katswiri wofufuza umachita ngati "apolisi amsewu" mdziko la madzi, kupewa zolephera za dongosolo zomwe zimayambitsidwa ndi sing'anga; Nyama yokwirira imayang'ana "kuchotsa madzi ndi madzi", kuchotsa madzi okwanira pa mapaipi owoneka bwino, pomwe mukutseka mwamphamvu kuti apange mphamvu yamagetsi.

2, zida ndi kapangidwe: kupanga maziko a magwiridwe antchito

Ntida za "chitsulo chachitsulo ndi mafupa achitsulo" a valavu imapangidwa kuchokera kuzinthu zosiyanasiyana. Chitsulo chimakhala chisankho chogwiritsidwa ntchito kwambiri pakupanikizika kotsika chifukwa cha kuvala bwino kwambiri komanso kwachuma; Chitsulo chosapanga dzimbiri, ndi katundu wake wosagwiritsa ntchito mankhwala, wakhazikika mwamphamvu m'minda ngati mafakitale a mankhwala ndi chakudya zomwe zimafunikira kuyera kwapamwamba; Kutentha kwambiri kwa zitsulo, kumbali ina, kumakhalapo ntchito yokhazikika komanso yodalirika yogwira ntchito kunkhondo yayikulu kutentha kwambiri komanso kukakamizidwa kwambiri monga mafuta otenthetsera komanso metaldurgy.

Ngakhale kuti mawonekedwe ake amkati amasiyanasiyana mosiyanasiyana, imakhala ndi mfundo zomveka bwino. Kutenga ma valves mwachitsanzo, njira yotsimikizika pakati pa chipata ndi mpando wa Valve ndiye chinsinsi chosindikizidwa, ndipo chipata chapadera cha chipata chowoneka bwino chimatha kulimbikitsa chipata choluka pansi; Kupangana kogwirizana pakati pa mpira wa mpira wa mpira ndi mphete yopindika ikhale yotsika kwambiri, ndikupangitsa kutseguka ndi kutseka kovuta komanso kosalala, pomwe pakuwonetsetsa kuti mukuchita bwino. Zopanga Zosangalatsazi zimapangitsa valavu kuti ikhalebe yokhazikika ndipo amagwira ntchito ngakhale pakugwiritsa ntchito nthawi yayitali.
