Yang'anani mwachidwi ku bizinesi iliyonse yomwe ikupangidwa ndi gulu lodziyimira pawokha, kukonza kamangidwe ka mavavu owongolera ma pneumatic, kaya ndizomwe zili pamwambazi zikuyenda bwino nthawi zonse, chitukuko cha chowonadi ichi ngakhale chidzakumana ndi zovuta zamitundu yonse. Kuti mukhale bizinesi yayikulu yokhala ndi mphamvu zolimba, mabizinesi onse akulu amamalizidwa ndikupita patsogolo ndi The Times. Chifukwa chake, mulingo wa luso laukadaulo pamapeto pake udzatsimikizira mwayi wampikisano komanso phindu lazachuma la bizinesiyo. Ndiyeno kusintha khalidwe ndi fano la valavu munda. Timapanga ndikupanga zinthu zotetezeka kwambiri, kudalirika kwambiri komanso kuchita bwino kwa zinthu zapamwamba, kupanga ndi kupanga zida ndi zida zabwino kwambiri zamagetsi zamagetsi zamagetsi zamagetsi kuphatikiza ma valve akulu ndi apakatikati, chitukuko ndi kapangidwe kazinthu zosiyanasiyana kuphatikiza, standardization, universality chitukuko. Zomwe zili zenizeni zikuwonetsa kuti mankhwalawa akukhudzana ndi gawo la mafakitale a valve, makamaka amatanthauza valavu yayikulu yamagetsi yamagetsi. Pali mitundu yambiri ya ma valve muzochita zamakono zamakono zamakono, monga valavu yachipata, valavu ya disc, valve valve ndi zina zotero. Valavu yamtunduwu, monga valavu yachipata, valavu ya disc ndiyomwe imayang'anira zipata zamadzimadzi, zomwe zimakhala zolemetsa, zokwera mtengo komanso zopanda kusindikiza. Valve yachipata imagwiritsidwa ntchito potsegula ndi kutseka kwamadzimadzi a nthunzi, chifukwa cha mapangidwe ake, sangathe kumaliza kusindikiza, ndipo ma valve ang'onoang'ono ndi ochepa kwambiri, mtengo wake ndi wokwera. Mankhwalawa akuwonetsa bwino valavu yayikulu yamagetsi yamagetsi, yomwe imagwiritsidwa ntchito ngati chisindikizo chachitetezo cha thupi la nthunzi, poyerekeza ndi valavu yachipata, valavu ya disc, valavu yapadziko lonse, osati opepuka kwambiri, komanso kusintha kwambiri mawonekedwe osindikiza a valve, amatha kupanga zosiyanasiyana. wa chitoliro chachikulu kudzera mu valavu, oyenera zosiyanasiyana mpweya chitoliro msewu, Mogwira kuthetsa vuto botolo kuti n'zovuta kusindikiza chipata valavu pamene ntchito nthunzi thupi madzi, makamaka yaing'ono m'mimba mwake valavu pamene ntchito nthunzi thupi madzi. . Mayankho aukadaulo amtunduwu ndi awa: Vavu yayikulu yamagetsi yamagetsi yamagetsi imakhala ndi chipolopolo chakunja, chipolopolo chakunja chimaperekedwa ndi mbale yoyambira ndi mbale yoyambira, mbale yoyambira imakonzedwa pamwamba pa mbale yoyambira, maziko. mbale imaperekedwa ndi dzenje lolowera mpweya wabwino, mbale yoyambira ndi mbale yoyambira yothandizira imaperekedwa ndi magawo ambiri owongolera, ndime yowongolera imaperekedwa ndi mbale yopukutira ndi mbale yoponderezedwa kuti igwiritse ntchito kutsegula ndi kutseka kwa chipata cholowera mpweya, Chombo choyezera kugwedezeka chimakonzedwa pakati pa mbale yoponderezedwa ndi mbale ya pachipata, ndipo chipangizo choyendetsa mzere chimalumikizidwa ndi mbale yokakamiza kukankhira kumanja ndi kumanzere molunjika. Kumtunda kwa malire gawo sensor amaperekedwa pa mbale yokakamiza kuyesa ubale wapakati pakati pa mbale yoponderezedwa ndi mbale ya pachipata, ndipo gawo laling'ono la gawo lotsika limaperekedwa pagawo lothandizira kuyesa ubale wapakati pakati pa mbale yokakamiza ndi wothandizira gawo lapansi. Mphete yosindikizira yotanuka imakonzedwa pakati pa mabowo a mbale yamphongo ndi mbale yoyambira. Kumbuyo kwa gawo lapansi kumaperekedwa ndi kapu yamafuta osindikizidwa omwe amaperekedwa ndi mafuta osindikizidwa a masamba. Chipangizo choyendetsera mzere chimakhala ndi nati yokhazikika ndikukhazikika mu mbale yosindikizira, ndipo chomangira cha mpira chimayikidwa mu nati, ndipo chomangira cha mpira chimalumikizidwa ndi chochepetsera, ndipo chochepetseracho chimakhazikika ndikukhazikika ndikukhazikika pankhosa yothandizira. Pini yolumikizira imakonzedwa pakati pa mbale yokakamiza ndi mbale ya pachipata. Nkhosa yamphongo imapatsidwa chokwera chosindikizira kuti atseke kusiyana pakati pa wononga mpira ndi nkhosa yamphongo. Chiwerengero chonse cha ndime yowongolera ndi inayi, ndipo chopatula chogwedeza chili ndi akasupe anayi ozungulira omwe amafanana ndi gawo lowongolera limodzi ndi limodzi, ndipo akasupe aliwonse a torsion amayikidwa pamzere wotsatira. Mbale yamphongo imaperekedwa ndi makina oyendetsa makina kuti achepetse chitetezo cha chochepetsera pambuyo pa kuwonongedwa kwa sensa ya gawo, ndipo chosinthira chachiwiri cha makina oyenda maulendo otetezera chochepetsera pambuyo pa kuwonongedwa kwa gawo lotsika la gawo lotsika limaperekedwa pa chithandizo. gawo lapansi. Pogwiritsa ntchito ukadaulo womwe uli pamwambapa, zotsatira zabwino za mankhwalawa ndi: Chifukwa chipolopolo chakunja cha valavu yamagetsi yamagetsi yamagetsi yayikulu-m'mimba mwake chimaperekedwa ndi mbale yoyambira ndi mbale yothandizira, mbale yoyambira imaperekedwa ndi dzenje la mpweya wabwino. , ndime yowongolera imaperekedwa ndi mbale yogudubuza ndi nkhosa yamphongo, pakati pa mbale yoponderezedwa ndipo nkhosa yamphongo imapatsidwa chowongolera chogwedeza, mbale yothamanga imagwirizanitsidwa ndi zida zoyendetsera galimoto kuti zipititse patsogolo kuyenda kwake kumanzere ndi kumanja, mbale kuthamanga amaperekedwa ndi kuchepetsa gawo sensa, kuthandiza mbale m'munsi amaperekedwa ndi otsika malire gawo sensa. Pogwira ntchito, chochepetsera chimakankhira mpirawo kuti uzungulire. Malinga ndi mtedza womwe uli mu mbale yosindikizira, kusuntha kwa wononga mpira kumasinthidwa kukhala kutsika ndi kutsika kwa mbale yosindikizira. Makina osindikizira amalimbikitsa kuti nkhosayo isunthe mmwamba ndi pansi molingana ndi kasupe wa torsion, kuti izindikire kutsegula ndi kutseka kwa valve. Mukafuna kutseka valavu, shaft yochepetsera imayendetsa screw ya mpira kuti izungulire, pali nati yofananira ndi zomangira za mpira pa mbale ya pressure, zomangira za mpira zimapangitsa kuti mbale ya pressure ipite mmwamba, ndipo mizati inayi yolondolera imatsimikizira molingana ndi mbale yoponderezedwa pamene nkhosa yamphongo ikupita pamwamba, mbale yoponderezedwa imakankhira kasupe wa torsion, torsion spring imakanikiza nkhosa yamphongo, nkhosa yamphongo ndi mbale yapansi ya bowo la mpweya pakati pa mphete yosindikizira, mphete yosindikizira ndi yokutidwa ndi osindikiza chomera girisi, nkhosa kuthamanga chisindikizo mphete, kuperekedwa kwa mpweya kuzimitsidwa. Sensa ya malo olepheretsa imazindikira ubale wapakati pa mbale yoponderezedwa ndi nkhosa yamphongo, ndipo mphamvu yokwanira yogwira ntchito yomwe imasonkhanitsidwa ndi kasupe wa torsion imatha kupondereza ndikusindikiza dzenje la mpweya wabwino. Sensa imapeza chizindikiro cha deta ndikuwongolera chochepetsera kuti asiye kuzungulira. Mwa njira iyi, pambuyo pa kusindikiza kwa nkhosa yamphongo ndikutseka dzenje la mpweya wabwino, mbale yoponderezedwayo siingathe kupitiriza kuchita masewera olimbitsa thupi, zomwe sizingangotsimikizira kuphatikizika kwa nkhosa yamphongo, komanso kupewa kuwononga zida zamakina. Pamene valavu iyenera kutsegulidwa, shaft yamoto imazungulira kumbali ina, komanso gawo laling'ono laling'ono lachidziwitso pamene mbale yoponderezedwa ikufika pamalo omwe anapatsidwa, chizindikiro cha deta chimapezeka, galimoto imasiya kuzungulira ndipo valve imatsegulidwa. . Mtundu wa mankhwalawa umagwiritsa ntchito kasupe wa torsion kuti ukhale ndi mawu otsatirawa, kuonetsetsa kuti nkhosa yamphongo iyenera kukakamizidwa, ndipo mizati inayi yolondolera imagwirizana, kuti nkhosa yamphongo ikhale ndi mphamvu yofanana; Chachiwiri, angapereke ntchito yamoto yopanda kanthu kuti iwonetsere malo amkati, injini yozungulira kwambiri kapena yocheperapo imatha kutsimikizira zotsatira zenizeni za kusindikiza, ndikuwongolera bwino moyo ndi ntchito ya valve; Chachitatu, molingana ndi pini yolumikizira nkhosa yamphongo, kukakamiza koyambirira kumaperekedwa ku kasupe wa torsion, kuti nkhosa yokhotakhota ndi nkhosa yamphongo isunge ubale wa cuboid, kotero kuti mpirawo ukazungulira, nkhoswe yokhotakhota imatha kugubuduka momasuka. pamzati wotsogolera, ndipo sikophweka kumamatira. Woyambitsa amapanga chosindikizira chosindikizira chamtundu woterewu cha valve yoyendera magetsi molingana ndi luso loganiza bwino. Vavu imasindikizidwa ndi kuthamanga kwapakati pakati pa nkhosa yamphongo ndi gasket yotanuka, ndipo gasket imakhala ndi kusungunuka kwina. Nkhosa yamphongo yokhayo imatha kufika pazitsulo zina zogwirira ntchito, zomwe zingathe kukwaniritsa kusindikiza bwino ndikuwongolera kwambiri makhalidwe osindikiza a valve. Chifukwa chakumbuyo kwa gawo lapansi kumaperekedwa ndi kapu yamafuta osindikizira, pitilizani kudzaza ndikuwonjezera kusindikiza kwenikweni kwa gasket zotanuka. Chifukwa chakuti nkhosayo ili ndi chokwera chosindikizira, imatha kutseka bwino kusiyana pakati pa wononga mpira ndi nkhosa yamphongo. Chifukwa nkhosa yamphongo imapatsidwa chosinthira choyendera cha makina, chosinthira chachiwiri choyendera chimaperekedwa pa mbale yoyambira. Ngati sensa yochepetsetsa yawonongeka, pamene mbale yoponderezedwa ili pafupi kwambiri ndi nkhosa yamphongo, malo otsekera oyendetsa makina oyendetsa makina adzasweka, ndipo mphamvu yochepetsera idzayima; Ngati otsika malire gawo sensa awonongedwa, mbale kuthamanga ndi pafupi gawo lapansi kuthandiza, yachiwiri makina chipangizo sitiroko lophimba zambiri chatsekedwa mfundo yopuma, reducer amasiya magetsi, kuti valavu akhoza kukhala bwino popanda kuwonongeka. Ambiri, mankhwala ntchito nthunzi chitetezo njira chisindikizo, poyerekeza ndi valavu chipata, valavu chimbale, valavu globe, osati opepuka kwambiri, ndi bwino kwambiri kusindikiza makhalidwe valavu, akhoza kupanga zosiyanasiyana chitoliro chachikulu kudzera valavu, oyenera panjira zosiyanasiyana zapaipi yolowera mpweya, kuthetsa bwino valavu yachipata yomwe imagwiritsidwa ntchito mumadzimadzi a nthunzi, makamaka valavu yaying'ono yomwe imagwiritsidwa ntchito mumadzimadzi a nthunzi kuti akwaniritse vuto la botolo. Zili ndi tanthauzo lalikulu kwambiri m'munda wa ma valve.
