Ukuhlukaniswa kwamaValuvu Ebhola Osayizi Omkhulu: Umhlahlandlela Ophelele

Uma kukhulunywa ngezinhlelo zokulawula uketshezi lwezimboni,ama-valve ebholaziphakathi kwezingxenye ezinokwethenjelwa neziguquguqukayo. Ikhono labo lokusingatha izinhlelo zokusebenza ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu libenza babaluleke kakhulu kuzo zonke izimboni. Lesi sihloko sihlola i-ukuhlukaniswa kwama-valve amabhola amakhulu, izinhlobo zabo, nokucatshangelwa okubalulekile lapho kufunwa umuntu othembekileumkhiqizi we-valve yebholanomaumphakeli eChina.

Iyini i-Ball Valve

A i-valve yebholaiyi-valve yokujika kwekota esebenzisa ibhola elingenalutho, elinezimbobo, kanye ne-pivoting ukulawula ukugeleza koketshezi. Lapho i-valve ivuliwe, imbobo yebhola iqondana nepayipi, ivumela uketshezi ukuba ludlule. Uma ivaliwe, ibhola lizungeza amadigri angu-90 ukuvimbela ukugeleza. Idizayini yayo elula iqinisekisa ukuqina, ukuvuza okuncane, kanye nokusebenza kalula.

Amavalvu ebhola anosayizi omkhulu, ngokuvamile achazwa njengalawo anobubanzi obungamayintshi angu-40 (DN1000) noma ngaphezulu, akhiwe ukuze asetshenziswe umsebenzi osindayo kuwoyela negesi, ukuhlanzwa kwamanzi, ukucutshungulwa kwamakhemikhali, kanye nokukhiqizwa kwamandla.

I-Valve yebhola: Izingxenye Ezibalulekile

Ukuqonda i-anatomy ye-ai-valve yebholakubalulekile ekukhetheni uhlobo olufanele lwezidingo zakho:

1. Umzimba: Izindlu izingxenye zangaphakathi; izinto ezivamile zihlanganisa insimbi engagqwali, cast iron, futhi carbon steel.
2. Ibhola: I-sphere ejikelezayo enebhore elawula ukugeleza.
3. Izihlalo: Dala uphawu phakathi kwebhola nomzimba.
4. Isiqu: Ixhuma i-actuator ebholeni ukuze ijikelezise.
5. I-Actuator: I-lever manual, igiya, noma uhlelo oluzenzakalelayo (ugesi/i-pneumatic).

Ngobaama-valve amakhulu webhola, ukwakhiwa okuqinile kanye nezindlela zokuvala eziqinisiwe kubalulekile ukuze umelane nezingcindezi ezinkulu kanye namazinga okugeleza.

Izinhlobo Zevalvu Yebhola: Ukuhlelwa Ngokusekelwe Kumklamo

Ama-valve ebhola ahlukaniswa abe izinhlobo eziningana ngokusekelwe ekwakhiweni kwawo nokusebenza kwawo:

Ivalve yebhola elintantayo

- Ibhola lilengiswa yizihlalo, lilungele osayizi abancane.
- Iyabiza kodwa ayifaneleki kangakoama-valve amakhulu webholangenxa yezidingo eziphakeme zetorque.

I-Trunnion Mounted Ball Valve

- Ibhola liqiniswa yi-trunnion (pivot), enciphisa itorque yokusebenza.
- Okuncanyelwayoama-valve amakhulu webholaemapayipini kawoyela negesi anengcindezi ephezulu.

I-Full Bore vs. I-Reduced Bore

- Isithukuthezi esigcwele: Ububanzi bebhola bufana nepayipi, kunciphisa ukwehla kwengcindezi.
- Isithukuthezi esincishisiwe: Ukuvulwa kwebhola elincane, elifanele amasistimu anesikhala.

I-Multi-Port Ball Valve

- Ifaka amachweba amaningi okuphambukiswa kokugeleza, asetshenziswa kumasistimu okusabalalisa ayinkimbinkimbi.

I-Cavity-Filled Ball Valve

- Idizayinelwe ukuvimbela ukungena koketshezi emgodini webhola, okubalulekile ekusetshenzisweni kwenhlanzeko noma ukugqwala.

Kungani Khetha I-Big Size Ball Valve

Ama-valve amakhulu webholazibalulekile ku-:

- Amasistimu wokugeleza okuphezulu: Ukuphatha kahle umthamo omkhulu woketshezi noma amagesi.
- Ukuqina: Yakhelwe ukuphatha imidiya elimazayo noma ebolayo.
- Ukulawula ukunemba: Qinisekisa ukuvala okuthembekile ezinhlelweni ezibucayi.

Ukukhetha Umkhiqizi Onokwethenjelwa Owe-Big Size Ball Valve

Lapho kutholwaama-valve amakhulu webhola, ngokubambisana nomuntu ohloniphekileimboni ye-valve yebholanomaumphakeli eChinainikeza izinzuzo ezifana nokuncintisanaintengo, ukwenza ngendlela oyifisayo, nokubambelela ezindinganisweni zamazwe ngamazwe (API, ANSI, ISO). Izici ezibalulekile okufanele zicatshangelwe:

1. Ikhwalithi Yezinto Ezibalulekile: Qinisekisa ukuthi ama-valve akhiwe ngama-alloys amelana nokugqwala.
2. Izitifiketi: Bheka i-ISO 9001, API 6D, noma amamaki e-CE.
3. Ukwenza ngokwezifiso: Khetha abakhiqizi abanikeza izixazululo ezihambisanayo zezidingo zokusebenza ezihlukile.
4. Ukusekela Ngemva Kokuthengisa: Iwaranti, usizo lobuchwepheshe, nokutholakala kwezingxenye ezisele.

I-China isalokhu iyisizinda somhlaba jikeleleukukhiqizwa kwe-valve yebhola, nabahlinzeki abahlanganisa ubuchwepheshe obuthuthukisiwe kanye nokusebenza kahle kwezindleko.

Isiphetho

Kusukaama-valve ebhola antantayoemsebenzini onzimatrunnion agibele amahhashi imiklamo, ukuqonda ukuhlukaniswa kweama-valve amakhulu webholaiqinisekisa ukukhethwa okuphelele kwezicelo zezimboni. Ukuthi ubeka phambiliintengo, ukuqina, noma ukunemba, ukusebenzisana nomuntu omethembayoUmhlinzeki we-valve yebhola waseChinaiqinisekisa ukufinyelela kuzixazululo ezisebenza kahle kakhulu.

Ezimbonini ezidinga ukulawulwa kokugeleza okuthembekile, ukutshala imali kukhwalithiama-valve amakhulu webholakusuka koqinisekisiweumkhiqizikuyisinqumo samasu esithuthukisa ukusebenza kahle nokuphepha.
