Iyini i-Relief Valve?

Iyini i-Relief Valve?

Ezindleleni ezahlukene zezimboni, ukuphathwa kwengcindezi kubalulekile ekuphepheni nasekusebenzeni kahle kwemisebenzi. Enye yezingxenye ezibalulekile ezisetshenziswa ukulawula ingcindezi yivalvu yokusiza. Lesi sihloko sizohlola ukuthi iyini ivalvu yokusiza, izinhlobo zayo, ukuthi isebenza kanjani, ukusetshenziswa kwayo, kanye nokubaluleka kokugcinwa okufanele.

Ukuqonda Ama-Valve Okusiza

I-valve yokusiza iyithuluzi lokuphepha elenzelwe ukulawula noma ukunciphisa ingcindezi ohlelweni. Ikhipha ngokuzenzakalelayo ingcindezi eyengeziwe emkhunjini noma ohlelweni lwamapayipi ukuvimbela umonakalo ongaba khona noma ukwehluleka okukhulu. Ama-valve okusiza abalulekile ezimbonini ezahlukahlukene, okuhlanganisa uwoyela negesi, ukucubungula amakhemikhali, ukukhiqizwa kukagesi, kanye nokwelashwa kwamanzi.

Indlela Ama-Valve Okusiza Asebenza Ngayo

Amavalvu okusiza asebenza ngokusekelwe esimisweni sokwehluka kwengcindezi. Lapho ingcindezi ngaphakathi kwesistimu idlula iphuzu elibekiwe elibekiwe, ivalvu yokusiza iyavuleka, ivumela uketshezi (uketshezi noma igesi) ukuba luphume. Lesi senzo sinciphisa ingcindezi ngaphakathi kwesistimu, sivimbele ukulimala kwemishini futhi siqinisekise ukusebenza okuphephile.

Izingxenye eziyisisekelo ze-valve yokusiza zifaka:

1. Umzimba: Isakhiwo esiyinhloko esigcina izingxenye zangaphakathi.

2. Isihlalo: Ubuso lapho ivalvu ivala khona ukuvimbela ukugeleza kwamanzi.

3. Idiski: Ingxenye enyakazayo evula futhi ivale ivalvu.

4. Intwasahlobo: Ingxenye ebamba idiski esihlalweni kuze kube yilapho ingcindezi esethiwe ifinyelelwa.

5. Indlela Yokulungisa: Indlela yokusetha ingcindezi oyifunayo lapho ivalvu izovuleka khona.

Uma ingcindezi yesistimu idlula ingcindezi ebekiwe, amandla asetshenziswa uketshezi anqoba amandla entwasahlobo, okwenza idiski isuke esihlalweni. Lokhu kuvumela uketshezi ukuthi luphume ohlelweni, kunciphisa ingcindezi. Uma ingcindezi yehla ngaphansi kwephuzu ebekiwe, amandla entwasahlobo avala ivalvu, amise ukugeleza.

Izinhlobo Zama-Valve Okusiza

Ama-valve okusiza afika ngezinhlobo ezahlukene, ngalinye lenzelwe izinhlelo zokusebenza ezithile kanye nezimo zokusebenza. Izinhlobo ezivame kakhulu zifaka:

1. Amavalvu Okusiza Agcwele Intwasahlobo: Lawa uhlobo lwevalvu yokusiza olusetshenziswa kakhulu. Asebenzisa isipilingi ukubamba ivalvu ivaliwe kuze kube yilapho ingcindezi ebekwe ifinyelelwa. Uma ingcindezi idlula iphuzu elibekiwe, isipilingi siyacindezelwa, okuvumela ivalvu ukuthi ivuleke.

2. Amavalvu Okusiza Asebenza Ngendiza: Lawa mavalvu asebenzisa ivalvu encane yokushayela ukulawula ukuvulwa nokuvalwa kwevalvu enkulu eyinhloko. Avame ukusetshenziswa ezisetshenziswayo ezinomfutho ophezulu futhi anganikeza ukulawula okunembe kakhudlwana phezu komfutho.

3. Amavalvu Okusiza Ukucindezeleka: Lawa mavalvu athembele esisindweni sesisindo esinyakazayo ukulawula ukuvulwa nokuvalwa. Awavamile kodwa angasetshenziswa ezinhlotsheni ezithile lapho kudingeka khona ukulawulwa kwengcindezi okunembile.

4. Amavalvu Okuphepha: Njengamavalvu okusiza, amavalvu okuphepha aklanyelwe ukuvula ngokushesha ngenxa yokucindezeleka ngokweqile. Ngokuvamile asetshenziswa ekusetshenzisweni komusi futhi aklanyelwe ukuvala ngokuqinile uma ingcindezi isibuyele esimweni sayo esijwayelekile.

5. Amavalvu Okusiza Ukucindezeleka (ama-PRV): Lawa mavalvu aklanyelwe ngqo ukuvikela ukucindezeleka ngokweqile ezinhlelweni zoketshezi. Avame ukusetshenziswa ezindaweni zokuhlanza amanzi kanye namanzi angcolile.

Ukusetshenziswa kwama-Relief Valve

Ama-valve okusiza asetshenziswa ezinhlobonhlobo zezicelo kuzo zonke izimboni. Ezinye izinhlelo zokusebenza ezivamile zifaka:

1. Imboni Kawoyela Negesi: Ama-valve okusiza abalulekile ekukhiqizweni kukawoyela negesi kanye nezinqubo zokucwenga. Asiza ekuphatheni ingcindezi emapayipini, emathangini okugcina izinto, kanye nasemishinini yokucubungula, ukuvimbela ukuvuza nokuqhuma.

2. Ukucubungula Amakhemikhali: Ezitshalweni zamakhemikhali, ama-valve okusiza avikela ama-reactor, amathangi okugcina, kanye neminye imishini ekucindezelekeni ngokweqile, okuqinisekisa ukusebenza okuphephile nokuvimbela izimo eziyingozi.

3. Ukukhiqizwa Kwamandla: Ezitshalweni zikagesi, ama-valve okusiza asetshenziswa ezinhlelweni zomusi ukuvimbela ukucindezeleka ngokweqile kuma-boilers nama-turbine, okuqinisekisa ukukhiqizwa kwamandla okuphephile nokuphumelelayo.

4. Ukwelashwa Kwamanzi: Ama-valve okusiza abalulekile ezindaweni zokwelashwa kwamanzi ukuze kulawulwe ingcindezi emapayipini nasemathangini, kuvinjelwe umonakalo emishinini futhi kuqinisekiswe ukuphepha kwamanzi.

5. Izinhlelo ze-HVAC: Ezinhlelweni zokushisa, zokungenisa umoya, kanye nezokupholisa umoya (i-HVAC), ama-valve okusiza asiza ukulawula ingcindezi emigqeni yesiqandisi, ukuvimbela ukwehluleka kwesistimu nokuqinisekisa ukusebenza kahle.

Ukubaluleka Kokunakekelwa Okufanelekile

Ukugcinwa kahle kwamavalvu okusiza kubalulekile ukuqinisekisa ukuthembeka kwawo nokusebenza kwawo kahle. Ukuhlolwa nokuhlolwa njalo kuyadingeka ukuqinisekisa ukuthi amavalvu asebenza kahle futhi asabela ezimweni zokucindezela ngokweqile njengoba kuhlosiwe. Eminye imikhuba ebalulekile yokulungisa ihlanganisa:

1. Ukuhlolwa Okuvamile: Ama-valve okusiza kufanele ahlolwe njalo ukuze kutholakale izimpawu zokuguguleka, ukugqwala, noma umonakalo. Noma yiziphi izinkinga kufanele zixazululwe ngokushesha ukuze kuvinjelwe ukwehluleka.

2. Ukuhlola: Ukuhlolwa njalo kwama-valve okusiza kubalulekile ukuqinisekisa ukuthi avuleka ngengcindezi efanele. Lokhu kungenziwa ngokuhlola ingcindezi noma ngokusebenzisa ibhentshi lokuhlola.

3. Ukuhlanza: Ukuqongelela kwemfucumfucu noma izinto ezingcolisayo kungathinta ukusebenza kwamavalvu okusiza. Ukuhlanza njalo kusiza ekugcineni ukusebenza kwawo.

4. Ukushintsha Izingxenye: Ngokuhamba kwesikhathi, izingxenye ezifana nezipringi kanye nezivalo zingaguga futhi zidinge ukushintshwa. Ukugcina izingxenye ezisele ziseduze kunganciphisa isikhathi sokungasebenzi uma kwenzeka kwehluleka.

5. Imibhalo: Ukugcina amarekhodi anemininingwane okuhlolwa, ukuhlolwa, kanye nemisebenzi yokulungisa kubalulekile ukuze kulandelwe imithetho yokuphepha kanye nokulandelela ukusebenza kwama-valve okusiza ngokuhamba kwesikhathi.

Ama-valve okusiza adlala indima ebalulekile ekugcineni ukuphepha nokusebenza kahle kwezicelo ezahlukene zezimboni. Ngokukhulula ngokuzenzakalelayo ukucindezela okweqile, avikela imishini nabasebenzi ezingozini zezimo zokucindezela ngokweqile. Ukuqonda izinhlobo ezahlukene zama-valve okusiza, ukusetshenziswa kwawo, kanye nokubaluleka kokugcinwa okufanele kubalulekile kunoma ubani ohilelekile ezimbonini ezithembele ekuphathweni kokucindezela. Ukuhlolwa njalo nokuhlolwa kwama-valve okusiza kungavimbela ukwehluleka okubi kakhulu futhi kuqinisekise ukusebenza okuphephile kwezinhlelo, ekugcineni kube negalelo empumelelweni iyonke yemisebenzi yezimboni.
