Ungayikhetha kanjani i-valve yesheke kahle?

Ezinhlelweni ezahlukahlukene zezimboni, bheka ama-valves asemqoka ukuvikela i-backflow yabezindaba futhi asetshenziswa kabanzi ekunikezelweni kwamanzi nasemanzi, amandla kaphethiloli, ama-metallurgy kanye nezinye izimboni. Yize i-valve yesheke ibonakala ilula ekwakhiweni, ekukhetheni kwangempela, uma izimo zokusebenza, indawo yokufaka noma izici eziphakathi azinakwa, kulula ukudala ukwehluleka kokusebenza noma ukulimala kohlelo.

Kwabasebenzi bempahla yokuthengwa kwempahla, ukuqonda ngokunembile amaphuzu asebenzayo kanye namaphoyinti wokukhetha we-valve ye-Check valve awakwazi ukukhulisa kuphela impilo yenkonzo yemishini, kepha futhi anciphise ngempumelelo izindleko zokulungiswa okulandelayo. Lokhu okulandelayo kuzochaza ukuthi ungakhetha kanjani ngokwesayensi i-valve efanelekile kusuka ezicini eziningana eziyinhloko.

1. Cacisa izimo zohlelo lokusebenza

Isinyathelo sokuqala ekukhetheni aBheka i-valveukuqonda amapharamitha ayisisekelo we-medium. Kufaka phakathi:

Uhlobo lwe-Fluid (Amanzi Ahlanzekile, Amafutha, Umusi, Uketshezi Olukhuni, njll.)

Ukushisa okuphakathi (lokushisa okuphansi, izinga lokushisa eliphakathi noma lokushisa eliphakeme)

Ingcindezi Yomsebenzi (noma ngabe uhlelo lokucindezela oluphezulu)

Ukuthi iqukethe izinhlayiya eziqinile (njengokuthuthwa kwendle, uhlelo lodaka)

Izimo zokusebenza ezahlukahlukene zinezidingo ezihlukile zesakhiwo kanye nokuqukethwe kwe-valve yesheke. Isibonelo, ekushiseni okuphezulu kanye nezinhlelo eziphakeme zokucindezela, kufanele kugwenywe uphawu lwenjoloba, futhi ama-valves we-Metal Seal Check kufanele anikezwe kuqala.

2.Khetha uhlobo lwesakhiwo esifanele

Bheka ama-valvesingahlukaniswa ikakhulukazi ezinhlotsheni ezilandelayo ngokuya ngesakhiwo sazo:

I-Lift Check Valve: Ilungele ukufakwa kumapayipi avundlile, ilungele izikhathi ezinamazinga aphezulu okugeleza kanye nokuvula njalo nokuvala. Isakhiwo sihlangene, kepha inkomba yokufaka iqine.

I-Swing Check Valve: Ukuzwela okuphezulu okuphezulu, ukulahleka kwengcindezi encane, elungele ingcindezi enkulu yamapayipi amakhulu.

I-Butterfly Check Valve: usayizi omncane, isisindo esikhanyayo, esisetshenziswa kakhulu ezinhlelweni ngezidingo zesikhala sokufaka, njengokupheka kwamapayipi amanzi.

I-Ball Check Valve: Ilungele amapayipi aqukethe izinhlayiya noma imidiya ye-viscous, engavimba ngempumelelo ukuqhekeka.

Hlola I-Valve Combination Pump Set: yakhelwe ngqo amaphampu wamanzi, kunganciphisa umthelela wesando samanzi ohlelweni.

Lapho uthenga, kufanele ukhethe uhlobo ngesakhiwo esifanelekile ngokususelwa ekucindezelweni kwesistimu, indawo yokufaka nezimpawu eziphakathi.

3.Fay Ukunakwa Kwezinto Zokwenziwa Nokusebenza Ngeamba

Izinto eziphambili zama-valves esheke zivame ukufaka i-iron iron, i-carbon yensimbi, insimbi engagqwali, ithusi, njll lapho ukhetha, kufanele ucabangele ukumelana kwawo ukugqwala, ukumelana nokushisa:

Izinhlelo ezijwayelekile zamanzi zivame ukusebenzisa i-iron noma ithusi

Ama-Complocinage Uketshezi angasebenzisa insimbi engagqwali

Kunconyelwa i-carbon yensimbi noma i-alloy yensimbi yengcindezi ephezulu kanye nezimo zokushisa eziphakeme

Ngaphezu kwalokho, ingaphezulu komhlaba yokubekwa uphawu kwe-Check valve kuthinta ngqo ukusebenza kokubekwa uphawu nempilo yenkonzo. Izilonda ezithambile zilungele abezindaba ezihlanzekile ekushiseni kwegumbi, kanti ama-wetal Seals alungele izinga lokushisa eliphakeme noma lokungcola

4.Kuqinisekisa ukuqondiswa kokufakwa kanye nezimo zesikhala

Bheka ama-valvesImvamisa babe nezidingo eziqinile kwindlela yokufaka. Ukufakwa okungalungile kuzodala ukuthi i-valve yehluleka ukuvula nokuvala ngokujwayelekile. Amaphuzu alandelayo kufanele aqondwe lapho uthenga:

Ingabe sikhona isikhala esanele sokufaka umzimba we-valve

Ngabe indlela yepayipi ivumela ukukhethwa kohlobo oluthile (njengohlobo lokuphakamisa kungafakwa kuphela ngokuvundlile)

Ingabe kufanelekile ekuhlolweni okuzayo nokulungiswa

Uma isikhala sinqunyelwe, mpo noma uhlobo lokuhlola uhlobo lwe-wafer lunganikezwa kuqala

5. Uma ucabanga ngokuqiniseka komnotho kanye nesiqinisekiso somkhiqizo

Yize i-valve yesheke iyingxenye encane, uma ukwehluleka kwenzeka, kungadala uhlelo lokubonisa, ukulimala kwemishini noma ukuvalwa. Ngakho-ke, lapho uthenga, awukwazi nje ukubheka intengo. Amaphuzu alandelayo kufanele agxile ku:

Ukuthi umkhiqizo udlulise ukuhlolwa kwekhwalithi

Ukuthi umphakeli uhlinzeka ngokusekelwa kwezobuchwepheshe ngemuva kokuthengisa

Ukuthi impilo ye-valve kanye nokulungiswa kokulungisa kuhlangana okulindelwe

Ukukhetha umenzi we-valve onamandla okuhlinzekela ezinzile nokusekelwa kwezobuchwepheshe kuzonciphisa kakhulu ingozi yokusebenza kwephrojekthi eyalandela.

Lapho uthenga ama-valves ebheka, kubaluleke kakhulu ukukhetha futhi uthenge okulungile

Ukukhethwa kwama-valves okuhlola kubonakala kulula, kepha empeleni kubandakanya izici eziningi zokwahlulela kwezobuchwepheshe. Kwabathengi bezinkampani, ukuqonda uhlobo lwayo lwesakhiwo, izimo zohlelo lokusebenza, nokusebenza kwezinto ezibonakalayo kuyisinyathelo sokuqala sokuqinisekisa ukusebenza okuzinzile kohlelo. Kunconywa ukuxhumana ngokuphelele nonjiniyela ngesikhathi sesigaba sokukhetha, futhi uma kunesidingo, thintana nomenzi ukuhlinzeka ngamapharamitha asampula noma iziphakamiso zokukhetha.

Besilokhu sigxile ezixazululweni ze-valve zezimboni iminyaka eminingi, futhi imikhiqizo yethu ikhava izinhlobo ezahlukahlukene zama-valves ezihlolayo, ukusekela ngokwezifiso, ukuholwa kwezobuchwepheshe kanye nezinsizakalo zokufaka. Uma unemibuzo ngesikhathi sokukhetha, sicela ukhululekeXhumana nathi.
