Okokuqala, kungani kabili uphawu valve ayikwazi ukusetshenziswa njenge hlola umphini?

Inzuzo ye- hlola umphini i-spool yisakhiwo sebhalansi yamandla, esivumela umehluko omkhulu wengcindezi, nokungalungile kwakho okuvelele ukuthi lezi zindawo ezimbili zokubekwa uphawu azikwazi ukuxhumana kahle ngasikhathi sinye, okuholela ekuvuza okukhulu. Uma isetshenziselwa ukwenziwa futhi iphoqelelwe ngezikhathi zokusika, kusobala ukuthi umphumela awumuhle, noma ngabe wenze ngcono okuningi (njenge-valve yemikhono evaliwe kabili), akufiseleki.

Okwesibili, i-valve elawula ukuthi kungani kuvulwa umsebenzi omncane wokuvula ama-valve amabili lapho kulula ukuxegiswa?

Ngomgogodla owodwa, lapho okuphakathi kunguhlobo oluvulekile lokugeleza, ukuzinza kwe-valve kuhle; Lapho okuphakathi kugeleza uhlobo oluvaliwe, ukuzinza kwe-valve kubi. I-valve yezihlalo ezimbili inezipuni ezimbili, i-spool esezansi ivaliwe, i-spool ephezulu iku-flow evulekile, ukuze kuthi lapho kuvulwa okuncane kusebenza, i-flow spool evaliwe kube lula ukudala ukudlidliza kwe-valve, okuyisizathu sokuthi kungani isihlalo-valve ezimbili ayikwazi ukusetshenziselwa umsebenzi wokuvula omncane.

Okwesithathu, yikuphi ukusebenza okuqondile kokuvimbela i-valve ukusebenza okungalungile, ukusebenza kwe-Angle stroke valve block kuhle?

I-stroke spool se-Straight straightling siyabambeka mpo, kanti okumaphakathi ukugeleza kungene kuphume, isiteshi sokugeleza egumbini le-valve kufanele lehle, ukuze indlela yokugeleza kwe-valve iba yinkimbinkimbi (umumo onjenge-S type eguquliwe). Ngale ndlela, kunezindawo eziningi ezifile, ezihlinzeka isikhala sendawo yokugunda, futhi ngokuhamba kwesikhathi, kubangele ukuvinjelwa. I-Angle stroke valve throttling direction isiqondiso esivundlile, ukugeleza okuvundlile kungene phakathi, ukuphuma okuvundlile, kulula ukususa indawo engcolile, ngasikhathi sinye indlela yokugeleza ilula, isikhala semvula esiphakathi sincane kakhulu, ngakho-ke ukuvimbela i-Angle stroke valve ukusebenza kuhle.

Isine. Kungani umehluko wokusika kwengcindezi weI-engela stroke valve enkulu?

I-engela stroke valve inqume umehluko wengcindezi inkulu, ngoba okuphakathi kufayela le- valve ipuleti eliwumgogodla noma i-valve elikhiqizwa amandla alandelanayo ngokushintshana kwe-torque shaft lincane kakhulu, ngakho-ke, lingamelana nokwehluka okukhulu kwengcindezi.

Okwesihlanu, kungani uhlangothi olulawula i-valve olulawula isiqu lincane?

Kubandakanya umthetho olula womshini: ukungqubuzana okukhulu okuslayida, ukungqubuzana okuncane okugoqekayo. Straight unhlangothi valve isiqu ukunyakaza phezulu naphansi, ukupakisha kancane khudlwana, kuzobeka iphakethe isiqu kuyinto Friend kakhulu, okuholela ukubuya enkulu. Kuze kube manje, isiqu se-valve senzelwe ukuba sincane kakhulu, futhi ukupakisha kuvame ukusetshenziswa nge-coefficient encane yokuphambana yokupakisha i-tetrafluorine, ukuze kuncishiswe umehluko wokubuyisa, kepha inkinga ukuthi isiqu sincane, kulula ukugoba, futhi impilo yokupakisha imfushane. Ukuxazulula le nkinga, indlela engcono kakhulu ukusebenzisa isiqu se-brigade valve, okungukuthi, uhlobo lwe-Angle stroke lokulawula i-valve, isiqu salo kunesiqu esiqondile sohlangothi obukhulu obungamahlandla ama-2 ~ ama-3, nokusebenzisa ukupakisha impilo ende ende, ukuqina kwesiqu kuhle , Ukupakisha impilo yinde, i-torque yokubanga incane, umehluko omncane wokubuya.

Okwesithupha, kungani amanzi asetshenzisiwe asebenzisa insimbi enjoloba i-butterfly valve, impilo yensiza ye-diaphragm valve impilo emfushane?

Isizinda samanzi esilahliwe siqukethe ukumuncwa okuphansi kwe-asidi noma i-alkali, okulimaza kakhulu irabha. Injoloba igqwalile ukunwetshwa, ukuguga, amandla aphansi, nge-rubber lining butterfly valve, umphumela wokusebenzisa i-diaphragm valve awumpofu umongo wayo ukumelana nokugqwala kwenjoloba. Ngemuva kokuthi i-valve yesikhumba se-diaphragm ithuthukiswe njenge-valve enhle yokumelana nokugqwala kwe-fluorine ulwelwesi lwe-diaphragm, kepha i-diaphragm ye-fluorine lining diaphragm valve ayikwazi ukumelana nokusonga okuphezulu nangaphansi futhi iphukile, okuholela ekulimaleni kwemishini, impilo ye-valve imfushane . Manje indlela engcono kakhulu ukwelashwa kwamanzi kukhethekilei-valve yebhola, ingasetshenziswa iminyaka engu-5 ~ 8.

Isikhombisa. Kungani i-valve enqunyiwe kufanele ivalwe kanzima ngangokunokwenzeka?

Ukwehla kokuvuza kuyadingeka ukusika i-valve, kuba ngcono. Ukuvuza kwe-valve yokuvala ethambile yikhona okuphansi kakhulu. Umphumela wokusika muhle impela, kepha awugqoki ukumelana futhi unokwethenjelwa okungekuhle. Kusukela kuzinga eliphindwe kabili lokuvuza okuncane nokufakwa uphawu okuthembekile, uphawu oluthambile alulungile njengophawu oluqinile. Njengomsebenzi ogcwele we-ultra-light control valve, evaliwe futhi embozwe ngokuvikela ingxubevange yokugqoka, ukuthembeka okuphezulu, isilinganiso sokuvuza esingu-10 ~ 7, ukwazile ukuhlangabezana nezidingo ze-valve enqunyiwe.
