I-valve yebhola lenyunyana yeqiniso iyi-valve enezingxenye ezintathu ezinamantongomane ahlanganisiwe. Lo mklamo ikuvumela ukuthi ususe wonke umzimba we-valve ophakathi ukuze usebenze noma ushintshe ngaphandle kokusika ipayipi.
Lona omunye wemikhiqizo engiyintandokazi engingayichazela ozakwethu abafana no-Budi e-Indonesia. Ii-valve yebhola lenyunyana yeqinisoakuyona nje ingxenye; ingumxazululi wezinkinga. Kunoma yiliphi lamakhasimende akhe ekucutshungulweni kwezimboni, ukuhlanzwa kwamanzi, noma i-aquaculture, isikhathi sokuphumula siyisitha esikhulu kunazo zonke. Ikhono lokwenzaukulungiswa ngamaminithi, hhayi amahora, kuyinzuzo enamandla. Ukuqonda nokuthengisa lesi sici kuyindlela ecacile yokudala isimo sokuwina lapho amakhasimende akhe onga imali futhi ambone njengochwepheshe obaluleke kakhulu.
Uyini umehluko phakathi kwe-valve yebhola lenyunyana kanye ne-valve yebhola?
Ubona ivalvu ejwayelekile eneziqephu ezimbili kanye nevalve yenhlangano yangempela. Zombili zimisa amanzi, kodwa eyodwa ibiza ngaphezulu. Uyazibuza ukuthi izindleko ezengeziwe zikufanele yini iphrojekthi yakho.
Umehluko oyinhloko ukugcinwa komugqa. Ivalvu yebhola ejwayelekile iyisimo esihlala njalo, kuyilapho umzimba wevalvu webhola wenhlangano wangempela ungakhishwa epayipini ukuze lilungiswe ngemva kokufakwa.
Lo mbuzo ufinyelela kusiphakamiso senani eliwumongo. Nakuba kokubili kuyizinhlobo zama-valve ebhola, indlela axhuma ngayo ohlelweni ishintsha yonke into mayelana nokusetshenziswa kwawo isikhathi eside. I-valve yebhola ejwayelekile, kungakhathaliseki ukuthi ucezu olu-1 noma ucezu olu-2, ixhunywe ngqo kwipayipi. Uma isinamathiselwe noma isifakwe umucu, iba yingxenye yepayipi. Umklamo wezinyunyana weqiniso uhlukile. Isebenza kakhulu njengengxenye ekhiphekayo. Kumakhasimende akwa-Budi, ukukhetha kuza embuzweni owodwa: Sibiza malini isikhathi sokuphumula?
Masiyihlukanise:
| Isici | Ivalvu Yebhola Ejwayelekile (1-pc/2-pc) | I-True Union Ball Valve |
|---|---|---|
| Ukufakwa | Glued noma intambo ngqo epayipini. I-valve manje isingunaphakade. | Iziqephu zomsila zinamathiselwe/zifakwe umucu. Umzimba we-valve ube usuvikelwa ngamantongomane enyunyana. |
| Isondlo | Uma izigxivizo zangaphakathi zihluleka, i-valve yonke kufanele inqunywe futhi ishintshwe. | Mane ukhulule amantongomane enyunyana bese uphakamisa umzimba wevalvu ukuze ulungiswe noma uwushintshe. |
| Izindleko | Intengo ephansi yokuthenga. | Intengo yokuthenga ephezulu ephezulu. |
| Inani Lesikhathi Eside | Phansi. Izindleko eziphezulu zabasebenzi zanoma yikuphi ukulungiswa okuzayo. | Phezulu. Izindleko zabasebenzi ziphansi kakhulu kanye nesikhathi sokuphumula sesistimu ukuze kulungiswe. |
Isebenza kanjani i-valve yebhola lenyunyana?
Ubona amantongomane amabili amakhulu kuvalvu kodwa awuqondi indlela osebenza ngayo. Lokhu kwenza kube nzima ukuchaza inzuzo kumakhasimende akho, avele abone i-valve ebiza kakhulu.
Isebenza kusetshenziswa uhlelo olunezingxenye ezintathu: izicucu ezimbili ezixhumene nepayipi nomzimba omaphakathi. Amantongomane e-union ajikijela ama-tailpieces, eqinisa umzimba endaweni yawo ngama-O-rings.
Umklamo ugqamile ngobulula bawo. Ngivame ukuhlukanisa eyodwa ukuze ngibonise uBudi ukuthi izingcezu zihlangana kanjani. Ukuqonda umakhenikha kwenza inani layo licace ngokushesha.
Izingxenye
- Umzimba Omaphakathi:Lena ingxenye eyinhloko equkethe ibhola, isiqu, nesibambo. Lenza umsebenzi wangempela wokulawula ukugeleza.
- Ama-tailpieces:Lawa amaphethelo amabili ane-solvent-welded unomphela (enamathiselwe) noma axhunywe kumapayipi. Anama-flange kanye nama-grooves ama-O-rings.
- I-Union Nuts:Lawa ngamantongomane amakhulu, anentambo. Zishelela phezu kweziqephu zomsila.
- O-Izindandatho:Lezi zindandatho zenjoloba zihlala phakathi komzimba ophakathi nendawo, okwenza uphawu oluphelele, olungangeni manzi uma lucindezelwe.
Ukuze uyifake, unamathisela ama-tailpieces epayipini. Bese, ubeka umzimba ophakathi phakathi kwawo futhi umane uqinise amantongomane amabili enyunyana ngesandla. Amantongomane acindezela umzimba ngokumelene nama-O-rings, okwenza uphawu oluvikelekile, olungavuzi. Ukuze uyisuse, uvele uhlehlise inqubo.
Iyini inhloso ye-trunnion ku-valve yebhola?
Uzwa igama elithi "trunnion mounted" futhi ucabange ukuthi lihlobene "nenyunyana yeqiniso." Lokhu kudideka kuyingozi ngoba kuyizici ezihluke ngokuphelele zezinhlelo zokusebenza ezihluke kakhulu.
I-trunnion ayihlangene nenyunyana. I-trunnion iphinikhodi yangaphakathi esekela ibhola ukusuka phezulu nangaphansi, esetshenziswa kumavalvu amakhulu kakhulu, anomfutho ophezulu, hhayi amavalvu e-PVC ajwayelekile.
Leli iphuzu elibalulekile lokucaciswa engilinikeza bonke ozakwethu. Ukudida le migomo kungaholela emaphutheni amakhulu emininingwane. "Inyunyana" ibhekisela ku-uhlobo loxhumano lwangaphandle, kuyilapho elithi “trunnion” libhekisela ku-indlela yokusekela ibhola yangaphakathi.
| Ithemu | Inyunyana Yeqiniso | I-Trunnion |
|---|---|---|
| Inhloso | Ivumela kube lulaukususwawomzimba we-valve osuka epayipini ukuze ulungiswe. | Ihlinzeka ngomshiniukusekelangenxa yebhola ngokumelene nomfutho ophakeme kakhulu. |
| Indawo | Kwangaphandle.Amantongomane amabili amakhulu angaphandle kwevalvu. | Ngaphakathi.Izikhonkwane noma ama-shafts abambe ibhola endaweni yawo ngaphakathi komzimba wevalvu. |
| Ukusetshenziswa Okuvamile | Bonke osayiziyamavalvu e-PVC, ikakhulukazi lapho kulindeleke khona ukulungiswa. | Ububanzi obukhulu(isb., > 6 amayintshi) namavalvu ensimbi anengcindezi ephezulu. |
| Ukuhambisana | Kuyafaneleka ngokwedlulelefuthi evamile kumasistimu e-PVC. Isici esibalulekile sokuthengisa. | Cishe ungalokothiesetshenziswa ezinhlelweni ezijwayelekile ze-valve yebhola ye-PVC. |
Amavalvu amaningi ebhola e-PVC, kuhlanganise namamodeli ethu e-Pntek, asebenzisa umklamo “webhola elintantayo” lapho ukucindezela kuphushela khona ibhola esihlalweni esingezansi komfula. I-trunnion ingeyezinhlelo zokusebenza ezidlulele kakhulu ngaphezu kokuphathwa kwamanzi okujwayelekile.
Iyini i-valve yenyunyana?
Uzwa usonkontileka ecela “ivalvu yenyunyana” bese ucabanga ukuthi kufanele asho ivalvu yebhola. Ukwenza ukucabangela kungasho uku-oda umkhiqizo ongalungile uma bedinga umsebenzi ohlukile.
“I-valve yenyunyana” yigama elivamile lanoma iyiphi i-valve esebenzisa ukuxhumana kwezinyunyana ukuze kukhishwe umugqa. Nakuba uhlobo oluvame kakhulu i-True Union Ball Valve, ezinye izinhlobo zikhona, njengeI-True Union Check Valves.
Igama elithi “inyunyana” lichaza isitayela sokuxhuma, hhayi umsebenzi wevalvu. Umsebenzi wevalvu unqunywa indlela yawo yangaphakathi—ibhola lokulawula ukuvala/ukuvala, indlela yokuhlola ukuvimbela ukugeleza emuva, nokunye. Kwa-Pntek, siphinde sikhiqize ama-True Union Check Valves. Banikeza inzuzo efanayo ncamashi namavalvu ethu ebhola lenyunyana yangempela: ukususwa kalula nokugcinwa. Uma i-valve yokuhlola idinga ukuhlanzwa noma isiphethu sishintshwe, ungasusa umzimba ngaphandle kokusika ipayipi. Uma ikhasimende licela ithimba likaBudi “ivalvu yenyunyana,” kuyithuba elihle lokubonisa ubuchwepheshe ngokubuza umbuzo olula wokulandelela: “Kuhle. Ingabe udinga i-valve yebhola lenyunyana yokulawula ukuvala/ukuvala, noma i-valve yokuhlola inyunyana ukuze unqande ukugeleza emuva?” Lokhu kucacisa i-oda futhi kwakha ukwethembana.
Isiphetho
I-valve yebhola yenhlangano yeqiniso ivumela ukukhishwa komzimba we-valve ngaphandle kokusika ipayipi. Lesi sici esibalulekile songa isikhathi esiningi, abasebenzi, nemali kunoma iyiphi isistimu
