Indlela yokukhetha i-valve efanelekile engenisiwe ngendlela efanele

(Incazelo efingqiwe)Ama-valve angenisiwe ikakhulukazi abhekisela kuma-valve avela kwamanye amazwe, ikakhulukazi ama-European, American and Japanese brand.

Ama-valve angenisiwe ikakhulukazi abhekisela kuma-valve avela kwamanye amazwe, ikakhulukazi ama-European, American and Japanese brand. Izinhlobo zomkhiqizo zama-valve ikakhulukazi zihlanganisa ama-valve ebhola angenisiwe, ama-valve okumisa angenisiwe, ama-valve alawulayo avela kwamanye amazwe, ama-butterfly valves angenisiwe, ama-valve okunciphisa ukucindezela avela kwamanye amazwe, ama-solenoid valve angenisiwe, njll. , indlela yokuxhuma, indlela yokusebenza, njll. Kuyadingeka ukukhetha i-valve efanele ngokusho kwezidingo zangempela nezici zomkhiqizo.
1. Izici ze-valve engenisiwe zihlanganisa izici zokusetshenziswa nezici zesakhiwo

1. Sebenzisa izici zamavalvu angenisiwe

Izici zokusetshenziswa zinquma ukusebenza kokusetshenziswa okuyinhloko kanye nobubanzi be-valve. Izici zokusetshenziswa kwe-valve zihlanganisa: isigaba se-valve (i-valve yesifunda evaliwe, i-valve elawulayo, i-valve yokuphepha, njll.); uhlobo lomkhiqizo (i-valve yesango, i-globe valve, i-butterfly valve, i-valve yebhola, njll.); i-valve Izinto zezingxenye eziyinhloko (umzimba we-valve, ibhonethi, isiqu se-valve, i-valve disc, indawo yokuvala); imodi yokudlulisa i-valve, njll.

2. Izici zesakhiwo

Izici zesakhiwo zinquma ezinye izici zesakhiwo sokufakwa kwe-valve, ukulungiswa, ukugcinwa kanye nezinye izindlela. Izici zesakhiwo zihlanganisa: ubude besakhiwo kanye nokuphakama okuphelele kwe-valve, ifomu lokuxhuma nepayipi (uxhumano lwe-flange, uxhumano lwentambo, uxhumano lwe-clamp, uxhumano lwangaphandle lwe-Threaded, uxhumano lwe-welding end, njll.); uhlobo lwendawo yokuvala (inlay inlay, ring threaded, surface, spray welding, valve body); isakhiwo se-valve stem (induku ejikelezayo, induku yokuphakamisa), njll.

Okwesibili, izinyathelo zokukhetha i-valve

Cacisa inhloso ye-valve kumishini noma idivayisi, futhi unqume izimo zokusebenza ze-valve: indawo esebenzayo, ingcindezi yokusebenza, izinga lokushisa lokusebenza, njll.; isibonelo, uma ufuna ukukhetha i-valve yokumisa i-LIT yaseJalimane, qinisekisa ukuthi i-medium iyisimusi, futhi isimiso sokusebenza singu-1.3Mpa, izinga lokushisa elisebenzayo lingu-200 ℃.

Nquma ububanzi obujwayelekile kanye nendlela yokuxhuma yepayipi exhunywe ku-valve: i-flange, intambo, i-welding, njll; isibonelo, khetha i-valve yokumisa i-inlet bese uqinisekisa ukuthi indlela yokuxhuma i-flanged.

Nquma indlela yokusebenzisa i-valve: imanuwali, kagesi, i-electromagnetic, i-pneumatic noma i-hydraulic, i-electro-hydraulic linkage, njll.; isibonelo, ivalvu yokuvala imanuwali ikhethiwe.

Nquma ukwaziswa kwegobolondo le-valve elikhethiwe kanye nezingxenye zangaphakathi ngokuvumelana nendawo, ingcindezi yokusebenza kanye nezinga lokushisa elisebenzayo lepayipi: insimbi ewugqinsi, insimbi ye-carbon, insimbi engagqwali, insimbi yengxubevange, i-asidi engagqwali-insimbi engazweli, insimbi empunga, insimbi egayiwe ethambile , i-ductile cast iron, i-copper Alloy, njll.; njengensimbi eyinsimbi ekhethelwe i-valve yembulunga.

Khetha uhlobo lwe-valve: i-valve yesifunda evaliwe, i-valve elawulayo, i-valve yokuphepha, njll;

Thola uhlobo lwe-valve: i-valve yesango, i-globe valve, i-valve yebhola, i-butterfly valve, i-throttle valve, i-valve yokuphepha, i-valve yokunciphisa ingcindezi, i-steam trap, njll;

Nquma imingcele yevalvu: Kumavalvu azenzakalelayo, qala ngokunquma ukumelana nokugeleza okuvumelekile, umthamo wokuphuma, umfutho ongemuva, njll. ngokwezidingo ezihlukene, bese unquma ububanzi obuncane bepayipi kanye nobubanzi bembobo yesihlalo sevalvu;

Nquma imingcele yejiyomethri ye-valve ekhethiwe: ubude besakhiwo, ifomu lokuxhuma i-flange nosayizi, ubukhulu be-valve ukuphakama ngemva kokuvula nokuvala, ukuxhuma usayizi wembobo ye-bolt nenombolo, usayizi wohlaka lwe-valve jikelele, njll.;

Sebenzisa ulwazi olukhona: amakhathalogi omkhiqizo we-valve, amasampula omkhiqizo we-valve, njll. ukuze ukhethe imikhiqizo efanelekile yamavalvu.

Okwesithathu, isisekelo sokukhetha ama-valve

Inhloso, izimo zokusebenza, nezindlela zokulawula ze-valve ekhethiwe;

Ubunjalo bendawo yokusebenza: ingcindezi yokusebenza, izinga lokushisa lokusebenza, ukusebenza kokugqwala, kungakhathaliseki ukuthi iqukethe izinhlayiya eziqinile, kungakhathaliseki ukuthi i-medium inobuthi, kungakhathaliseki ukuthi iyindawo evuthayo noma eqhumayo, i-viscosity ye-medium, njll.; isibonelo, uma ufuna ukukhetha i-valve ye-solenoid engenisiwe ku-LIT, i-medium Ngaphezu kwendawo evutha umlilo neqhumayo, kuvamise ukukhethwa ivalve ye-solenoid yokuqhuma-nobufakazi; esinye isibonelo ukukhetha i-valve yebhola ye-German Lit LIT. I-medium iqukethe izinhlayiya eziqinile, futhi i-valve yebhola emise okwe-V-evalwe uphawu ngokuvamile iyakhethwa.

Izidingo zezici ze-valve fluid: ukumelana nokugeleza, umthamo wokukhipha, izici zokugeleza, izinga lokuvala, njll.;

Izidingo zobukhulu bokufaka nobukhulu bangaphandle: ububanzi obujwayelekile, indlela yokuxhuma kanye nobukhulu bokuxhuma ngepayipi, ubukhulu bangaphandle noma imikhawulo yesisindo, njll.;

Izidingo ezengeziwe zokuthembeka komkhiqizo we-valve, impilo yesevisi, kanye nokuqhuma-ukusebenza kobufakazi bemishini kagesi (inothi lapho ukhetha imingcele: Uma i-valve izosetshenziselwa izinjongo zokulawula, imingcele eyengeziwe elandelayo kufanele inqunywe: indlela yokusebenza, ukugeleza okuphezulu nokuncane izidingo , Ukwehla kokucindezela kokugeleza okujwayelekile, ukwehla kwengcindezi lapho kuvalwa, ukucindezela okuphezulu nokuncane kokungena kwe-valve).

Ngokwesisekelo-esibalulwe ngenhla kanye nezinyathelo zokukhetha ama-valve, kuyadingeka ukuba nokuqonda okuningiliziwe kwesakhiwo sangaphakathi sezinhlobo ezihlukahlukene zamavalvu lapho kukhethwa ama-valve ngendlela enengqondo nangendlela efanele, ukuze kwenziwe isinqumo esifanele ngevalvu ethandwayo.

Ukulawula okuphelele kwepayipi i-valve. Izingxenye zokuvula nezokuvala zevalvu zilawula ukugeleza kwe-medium epayipini. Ukuma kwendlela yokugeleza kwe-valve kwenza i-valve ibe nesici esithile sokugeleza. Lokhu kufanele kucatshangelwe lapho kukhethwa i-valve efaneleka kakhulu yohlelo lwamapayipi.
Fingqa futhi ufingqe izici eziningana ezinkulu zokukhetha: nquma ukuthi iyiphi i-valve umsebenzi ongakhetha, uqinisekise izinga lokushisa nokucindezela okuphakathi, uqinisekise izinga lokugeleza kwe-valve nobubanzi obudingekayo, uqinisekise impahla ye-valve, kanye nendlela yokusebenza;
