Inqubo yokuvuza kwangaphakathi kwevalvu? Izinyathelo zokuphepha zokusebenza kwe-valve? Imininingwane yokudweba i-valve nokumaka

1, thola indlela yokuvuza yangaphakathi kwe-valve ngemva kokuba i-valve ivaliwe amahora angu-4-6, sebenzisa i-thermometer ye-infrared ukukala isiqu (eduze nomzimba we-valve) noma u-150mm phansi komfula wezinga lokushisa lensimbi yomzimba we-valve, elingaphezu kuka-70 ℃, ikhonjwa “njengokuvuza kwangaphakathi”. Le ndlela isetshenziswa kumavalvu amaningi avuzayo angaphakathi. Kodwa emsebenzini wangempela, sihlangabezane namacala akhethekile alandelayo1) ngenxa yokuma kwepayipi, kukhona ama-valve ngaphambi nangemva kokuphazamiseka kwesitimu sokushisa okuphezulu, njengokuxhunywa kumfutho wepayipi, ukudonsa kweshubhu le-jellyfish.
Okokuqala, indinganiso yokunquma ukuvuza kwe-valve
1, thola indlela yokuvuza kwe-valve
Ngemva kwamahora angu-4-6 okuvalwa kwevalvu, sebenzisa ithemometha ye-infrared ukukala izinga lokushisa lensimbi esiqwini (eduze nomzimba) noma u-150mm ezansi nomfula womzimba, uma ungaphezu kuka-70 ° c, kuthathwa ngokuthi “ukuvuza kwangaphakathi”. Le ndlela isetshenziswa kumavalvu amaningi avuzayo angaphakathi.
Kodwa-ke, emsebenzini wethu osebenzayo, sihlangabezane nalezi zimo ezikhethekile ezilandelayo:
(1) Ngenxa yokuma kwepayipi, kukhona amanye ama-valve ngaphambi nangemuva kokuphazamiseka kwesitimu esishisa kakhulu, njengokuxhunywa epayipini lokucindezela, isicupho sepayipi le-jellyfish noma umnyango wokudonsa amanzi, lawa mavalvu ngisho noma kuvuza okuqinile, i-valve. izinga lokushisa lesiqu lizoba ngaphezu kuka-70 ℃.
(2) Eceleni necele finyelela umnyango womgibe noma umnyango wokudonsa amanzi we-trap kanye nepayipi le-jellyfish. Uma indawo yevalvu iseduze nepayipi eliyinhloko, inqobo nje uma noma iyiphi i-valve yegatsha epayipini ivuza, izinga lokushisa lamanye ama-valve lizokhuphuka lifike ngaphezu kuka-70℃, njenge-valufa yokudonsa kubhayela, i-value yesitimu esishisa kakhulu, njll. Ngakho-ke, UKUNIKEZWA KOKUVUZA NGAPHAKATHI KULAWAMAVAVA KUFANELE KUYENZIWE NGEZINYE IZINDLELA, NJENGOKUKALWA AMASHISHINI OTHANDO LOMNYANGO NOMA AMAGUGU ESIQINISO SOKUNQOBA UKUHLOLA OKUVUZA NGAPHAKATHI.
Okwesibili, ukusebenza kwe-valve kubalulekile okudinga ukunakwa
1. Ngeminyango yezandla yamanzi okudonsa amanzi esistimu yokushisa, kufanele iqiniswe futhi isigamu sehora ngemva kokuqedwa kokusebenza ukuze kuqedwe igebe le-valve elibangelwa ukunwetshwa kokushisa nokunciphisa okubandayo.
2. Ngepayipi yokushisa enomnyango owodwa noma emibili, ukulandelana kokusebenza kwe-valve kanje: vula umnyango kanye ngaphambi kokuvula umnyango kabili; Uma uvala, kufanele uqale uvale umnyango kabili bese uvala umnyango futhi.
I-3, ukuze kusetshenziswe i-valve yesango, ingavalwa ngokugcwele noma ivuleke ngokugcwele, ungavumeli isigamu esivulekile sesigamu esivaliwe, ukuze kuncishiswe umonakalo wokushaywa kwe-valve.
Okwesithathu, ukuphatha ama-valve kubalulekile okudinga ukunakwa
Iyunithi 1, ngaphambi kokuqala kokuhlolwa ngakunye kukagesi, i-pneumatic valve, inqubo yokuhlola, kufanele kube uchwepheshe osendaweni yokuqapha isimo sokunyakaza kwe-valve kanye ne-damper, hlola induku yokuxhuma i-actuator kanye nephinikhodi akufanele kube ukuxega, ukugoba nokuwa, hlola izikhombisi-ndlela zokuvulwa kwe-DCS kanye ne-in situ kufanele ihambisane, kukhona umnyango kagesi wokumisa ophakathi ukuze uhlole isitobhi esiphakathi sijwayelekile. Lungisa indlela yokushintsha isicabha ilungile, isenzo esivumelana nezimo, nge-loop engenelayo ekuhlolweni okufanelekile kokuxhumanisa kochwepheshe, idivayisi yokuhlola umoya womoya kufanele iguquguquke, akukho ukuvuza kanye nesenzakalo esingavamile, ukuhlolwa kufanele kumise ukuhlolwa uma kungavamile, kwazise ngesikhathi esifanele abasebenzi bezokulungisa ukuthi babhekane. nge.
Iyunithi 2, isikhathi ngasinye lapho uqala kufanele kube ngokuhambisana ngokuqinile nezinhlinzeko zokusebenza okuhambisanayo, isango lamanzi i-ShuFang kufanele lihlole ukuvala ngomthethonqubo, i-watergate ngayinye ye-ShuFang ivaliwe (amahora angu-10) ngemva kwamahora angu-6, ngemva kwesango lamanzi. inkomba yokushisa kwe-hydrophobic, kufanele isekelwe epayipini le-valve ngemuva kokuhlaziya nokwahlulela ukuthi ukuvuza kwe-valve, izinga lokushisa elibonisa ukuthi akukho izinga lokushisa elibonisa ukuthi lincane ngemva kwe-watergate, I-thermometer ye-infrared isetshenziselwa ukukala izinga lokushisa kwezindonga zamapayipi angaphambili nangemuva. i-valve noma ukuzwa ukuze kutholakale ukuthi i-valve iyavuza. Okufana nokuvuza kwe-valve kagesi noma ye-pneumatic, kufanele kuvalwe umnyango kagesi we-hydrophobic noma umnyango we-pneumatic wokuhlukanisa umnyango, ngomnyango kagesi we-hydrophobic, umnyango we-pneumatic ngaphandle komnyango wokuhlukanisa owenziwe ngesandla, njengokuvuza, kufanele unyakaziswe ukuze uvale umnyango kagesi, futhi ulahlekile nokuxhumana. ukwelashwa kwesondlo. Okufana nokuvuza komnyango okwenziwa ngesandla, ukwelashwa nokugcinwa kokuxhumana okulahlekile.
I-3, isikhathi ngasinye ngaphambi kokuvala iyunithi, ukukhubazeka kwe-valve (ukuvuza) kufanele kuhlolwe, i-valve yokuvuza kufanele igibele futhi yazise umnyango wezokulungisa ofanele.
4. Enkambisweni yokuvula nokumisa noma ngenqubo yokukhipha ingcindezi, ngemva kokuvula isango lamanzi (ukukhipha) isango lamanzi, hlola ukuthi ingabe kukhona izinga lokushisa ngemuva kwe-valve noma i-throttle hole (umgibe), ukuqinisekisa ukuthi ingadlala indima amanzi okudonsa amanzi, ukuvimbela ukugqwala okubangelwa amanzi epayipi lokushisa okubangelwa ukuvaleka kwevalvu noma ipayipi noma i-throttle hole (ugibe).
I-VALVE PENTING KANYE NE-MAKHITHA ISIYALEZO SOKUTHI UKUKHOMBISWA KWEMVELI OKUFANELE KUZOPENDWA EMBUSWENI ONGAMSHINI WOMZIMBA WEVALVI KANYE NEBONNET, FUTHI UKUHLOLWA KOMKHAWU OKUVALWAYO KUZOPENDWA ESIPHANDLENI SOKUTHUMELA, ESANDWENI SOKUTHUMELA, KANYE ESANDWENI SOKUSHIYA NJENGOBA KUBALULEKILE KWITHEBULA NGEZANSI. Umbala kapende wendlela yokudlulisa ucaciswe kanje: idivayisi kagesi, uhlobo olujwayelekile olupendwe ngokumpunga okuphakathi; Okuthathu kokukodwa (ngaphandle, okungangenwa ukuqhuma, okunqanda ukugqwala) uhlobo olupendwe isibhakabhaka esiluhlaza; I-pneumatic, hydraulic, gear transmission kanye nezinye izinto zokudlulisela ezinombala womkhiqizo wevalvu.
1. Ukuhlonza izingxenye zevalvu
Egobolondweni le-valve, kunomugqa ovundlile onomcibisholo. Izinombolo ezingenhla komugqa ovundlile zibonisa izinga lokucindezela okulinganiselwe, kanti ezinye zibonisa ipharamitha yezinga lokushisa nokucindezela kokusebenza. Isibonelo, i-PNl0 ne-PT510 zisetshenziswa ngaphansi kwemingcele yokusebenza engu-10MPa no-510℃. Inombolo engezansi komugqa ovundlile ikhombisa ububanzi bepayipi lokuxhuma.
→ ikhombisa ukuthi i-valve iqonde phakathi, indawo ephakathi nendawo nokugeleza komzila, emgqeni ofanayo omaphakathi noma ohambisanayo.
I-Chrysene > ibonisa ukuthi ingxenye ye-valve iwuhlobo lwe-engeli yesokudla, i-medium isebenza engxenyeni yokuvala.
Ibonisa ukuthi i-valve inezinhlangothi ezintathu futhi i-medium inezikhombisi-ndlela zokugeleza eziningana.
