Valavu ngati chida chabadwa kwa zaka masauzande ambiri

Valavundi chida chomwe chimagwiritsidwa ntchito pofalitsa ndi kuyendetsa mafuta ndi madzi osakwana zaka chikwi.

Pakadali pano, m'mapaipi amadzimadzi, valavu yovomerezeka ndi chinthu chowongolera, ndipo ntchito yayikulu ndikusiyanitsa zida ndi njira yolowera, kuletsa kusuntha, kuwongolera ndikutulutsa ndikuthana ndi kutulutsa. Popeza ndikofunikira kusankha valavu yoyenera kwambiri yovomerezeka kwambiri pamapaipi, ndikofunikira kwambiri kumvetsetsa mikhalidwe ya valavu ndi masitepe ndi maziko osankha valavu.

Kupanikizika kwa valve

Kupanikizika kwam'madzi kwamphamvu kumatanthauza kukakamizidwa komwe kumayenderana ndi mphamvu yamakina yamphamvu, ndiye kuti, ndi njira yolimbikitsira valavu yomwe ili patenthedwe, yomwe ikukhudzana ndi zinthu za valavu. Kupanikizika kwa ntchito sikofanana, chifukwa chake, kupanikizika kwadzina ndi gawo lomwe limatengera zomwe valavu ndipo imagwirizana ndi kutentha koyenera komanso kupsinjika kwa zinthuzo.

Valavu ndi malo munthawi ya sing'anga yozungulira kapena dongosolo la kupanikizika, lomwe limagwiritsidwa ntchito kusintha mayendedwe kapena kukakamizidwa kwa sing'anga. Ntchito zina zimaphatikizapo kutseka kapena kusinthanitsa paolota, kuwongolera mayendedwe, kusintha ma media poyenda, ndikuwongolera kapena kuwongolera kapena kuwongolera.

Ntchito izi zimatheka chifukwa cha kutseka kwa valavu. Kusintha kumeneku kungachitike pamanja kapena zokha. Ntchito yamanja imaphatikizanso kugwira ntchito kwa kuyendetsa galimoto. Mavalidwe ogwirira ntchito pamanja amatchedwa Maseme. Valavu yomwe imalepheretsa kubweza imatchedwa valavu ya cheke; Yemwe amawongolera kupsinjika kumatchedwa valve ya chitetezo kapena valve wopulumutsa chitetezo.

Pakadali pano, makampani a valavu akwanitsa kubala osiyanasiyanaMavesi pachipata, ma valves Grobhableb, mavuvu opumira, ma valve plue, ma valves a mpira, mavavu amagetsi, ma valves osungunula, ma strave a Steam ndi mavalo otsekeka mwadzidzidzi. Valavu yamagawo 12, oposa 3,000, komanso zolemba zoposa 4000; Kupanikizika kwakukulu ndi 600mA, m'mimba mwa nomwel ndi 5350mm, kutentha kwakukulu kopitilira 1200℃, kutentha kocheperako kuli -196℃, ndipo sing'anga woyenera ndi madzi, nthunzi, mafuta, mpweya wa chilengedwe, medic yolimba (monga gwiritsani ntchito Nitric acid, sitric ndende acid, etc.).

Yang'anirani Kusankha Kwambiri:

1. Pofuna kuchepetsa nthaka pachikuto chakuya mapaipi,Nyama ya Gulugufenthawi zambiri amasankhidwa pamapaipi akuluakulu kwambiri; Choyipa chachikulu cha valavu ya gulugufe ndikuti mbale yagunda ya gulugufe amakhala gawo lina la madzi, lomwe limawonjezera kutaya mutu wina;

2. Ma Valvel Allvel amaphatikizaMavalidwe a Gulugufe, Mavesi pachipata, ma valve a mpira ndi ma valve a Pulging, etc. Mavalidwe osiyanasiyana omwe amagwiritsidwa ntchito mu network ya mathithi ayenera kuganiziridwa posankha.

3. Kuponyera ndi kukonza ma valve a mpira ndi mapiri ovuta ndizovuta komanso zodula, ndipo nthawi zambiri zimakhala zokwanira mapaipi ang'onoang'ono komanso apakatikati. Mbale Valve ndi Valve Valve Sungani bwino za valavu imodzi ya chipata, yotuluka yamadzi yaying'ono, kusindikiza kosinthika, kukonza kosinthika, kukonza kosinthika. Valive valavunso ilinso ndi zabwino zofananira, koma gawo lodutsa madzi si bwalo labwino.

4. Ngati sichikukhudza kwambiri kuya kwa dothi, yesani kusankha chipata cha chipata; Kutalika kwa chipata chamagetsi

5. M'zaka zaposachedwa, chifukwa chosintha matekinoloje, kugwiritsa ntchito mchenga wowuma kungapewe kapena kuchepetsa kukonzanso, motero kumachepetsa ndalama, motero kuthekera kwa mitengo yamiyala yayikulu yomwe imagwiritsidwa ntchito pofufuza. Ponena za mzere wa chiwonongeko cha kukula kukula kwa mabiberi, ziyenera kulingaliridwa ndi kugawanika malinga ndi momwe zinthu zilili.
