I-Lug vs. Wafer Butterfly Valves: Umehluko Oqakathekileko & Umhlahlandlela

Amavalvu we-butterflyidlala indima eqakathekileko ekulawuleni ukugeleza kweengazi ezihlukahlukeneko namagesi. Hlangana nemihlobo ehlukileko yamavalvu we-butterfly, ama-lug butterfly valve kanye ne-waferamavalvu wevithaminiziinkhetho ezimbili ezisetjenziswa khulu. Yomibili imihlobo yamavalvu inemisebenzi ehlukileko begodu ilungele ukusetjenziswa okuthileko.I-TWSsizokuhlola ukufana nokungafani kwabo esihlokweni lesi, ngethemba lokukusiza wenze iinqunto ezizwakalako lokha nawukhetha ivalvu efaneleko.

I. Ukufana hlangana kwabo.

1. UkusebenzaPisimiso.

Bobabili amavalvu womhlobo we-wafer kanye namavalvu womhlobo we-lug alawula izinga lokugeleza kwe-medium ngokujikelezisa idiski yevalvu. I-engele yokujikeleza kwediski yevalvu ingaba hlangana kwama-0 ukuya ku-90 wamadigri, lokho kutjho bona, ivalvu ivuleke ngokupheleleko kuma-90 wamadigri begodu ivaliwe ngokupheleleko kuma-0 degrees. Lokhu kusimiso sokusebenza kwamavalvu we-butterfly.

2. OkufanakoUbuso nobuso

I-wafer butterfly valve kanye ne-lug butterfly valve yenzelwe njengemihlobo emincani, ethatha isikhala esincani begodu ilungele ukufakwa erherhweni lamapayipi enendawo elinganiselwe.

3. Umklamo ojwayelekileko:

Kokubili kukhambisana namazinga webubulo weentjhabatjhaba, kulula ukuzihlanganisa namafletjhi ajwayelekileko, begodu kungathathelwa indawo lula eenhlelweni ezikhona.

II.Ini's umehluko?

Bobabili amavalvu womhlobo we-wafer kanye namavalvu womhlobo we-lug atjho indlela yokuhlanganisa amavalvu womhlobo we-lug, ngobude obufanako besakhiwo kanye neenhloso ezifanako, kodwana kunomehluko omkhulu ekuklameni, ekufakweni, ekusetjenzisweni, eendlekweni, nezinye izinto.

1.UkutlamaDumehluko

I-lug butterfly valve: Zombili iinphetho zomzimba we-valve zenziwe nge-lugs eneentambo, ezilungisa khulu ukulungisa i-valve.

I-wafer butterfly valve: Ngokuphikisako, ayinawo ama-insert anentambo, kodwana iboshwe hlangana nama-flange amabili, ngamabhawudo adlula nge-flange yepayipi nomzimba we-valve ukuyilungisa. Okutjho bona, yakhiwe ngokugandeleleka kwamabhawudo acindezela i-flange yepayipi.

2.UkufakwaPikambiso.

• Lugivalvu yevivane:

Amavalvu we-lug butterfly alungele amapayipi adinga ukutlhogonyelwa njalo nofana ukuhlukaniswa njalo. Ukufakwa okufakwe ngentambo kulula ukukufaka nokukhipha ngaphandle kokulimaza yoke ihlelo lamapayipi. Ivalvu yevivane ephuma ngaphandle ingafakwa ekupheleni kwepayipi bese isetjenziselwa ivalvu yokuphetha.

- Qinisekisa bona ama-lugs ahlangene kuhle namabhawudo we-flange ukugwema ukugandeleleka emzimbeni wevalvu.

- Sebenzisa izinto ezifaneleko ze-gasket lokha nakutlhogekako ukukhandela ukuvuza, khulukhulu eenhlelweni ezinefuthe eliphakathi.

- Qinisa amabhawudo ngokulinganako ukugcina umfutho ofanako ngaphakathi kwevalvu.

• I-waferivalvu yevivane:

Amavalvu we-wafer butterfly afaneleka khulu ukuhlanganisa zombili iinphetho zamapayipi ebujameni lapho isikhala sincani, kodwana angeze asetjenziswa njengamavalvu wokugcina ngombana angahlukana.

- Qinisekisa ukuhambisana kwe-flange (isib. i-ANSI, i-DIN) ukuqinisekisa ukuvalwa.

- Balekela ukuqinisa khulu amabhawudo we-flange ukukhandela ukuguquguquka komzimba womtjhini.

- Ifakwe erherhweni ngokudlidliza okuncani kwepayipi ukukhandela ukukhululeka.

3. Indlela yokuvala.

Ivalvu ye-lug butterfly inikela ngokuvala okuqinileko ngebanga lokuhlanganiswa okuneentambo kanye namabhawudo wokuphepha, ukuqinisekisa ukusebenza okungavuziko nokukhandela ukugeleza kwamanzi emuva.

Ngokuphikisako, i-wafer type butterfly valve ithembele ekucindezelweni hlangana nama-flange amabili ukufikelela ukuvala okuthembekileko, njeke kufuze ifakwe ihambisane ngokupheleleko nepayipi ukubalekela ukungalungi nokuvuza.

4. DN&PN

- I-wafer on butterfly valves ivamise ukuba mincani kune-DN600, begodu i-single flange butterfly valves ingasetjenziselwa ububanzi obukhulu. Ngokuvamileko zilungele ubujamo lapho umfutho ungaphasi kwe-PN16.

-Ivalvu ye-lug butterfly inobubanzi obukhulu begodu ingaphatha amazinga aphezulu wokugandeleleka, ukuya ku-PN25, ngombana ukufakwa kwe-lug butterfly valve kuvikelekile.

5. Cost

Amavalvu we-lug butterfly kanye namavalvu we-wafer butterfly ahlukile ngokusebenza kuhle kweendleko.

Amavalvu we-wafer butterfly avamise ukonga khulu ngombana anemiklamo elula, ukusebenza okulula, begodu atlhoga izinto ezincani.

Ivalvu ye-lug butterfly idinga ukufakwa ngentambo, njeke ikambiso yokwenza umtjhini iyinkimbinkimbi.

III. Cisiphetho

Kokubili amavalvu we-lug butterfly nama-wafer butterfly valve asetjenziselwa ukulawula ukugeleza kwe-fluid, kodwana kunomehluko omkhulu ekuklameni, ekufakweni, ekuvaleni, ebubanzini, ekulinganisweni komfutho, kanye neendleko hlangana nalokhu kokubili. Lokha nawukhethako, kungatholakala ngokuya ngeendingo ezithileko: nangabe kutlhogeka ukuhlukaniswa nokutlhogonyelwa njalo, kuhle ukukhetha umhlobo wendlebe ephuma ngaphandle; Nangabe isikhala sincani begodu iindleko ziyinto ekhathazako, i-wafer ekuklameni ilungele khulu. Ukuzwisisa umehluko lo kungakusiza bona ukhethe amavalvu ahambelanako begodu ufinyelele ukulawula ukugeleza okusebenzako nokuthembekileko.I-TWSakusiye kwaphela umlingani othembekileko wekhwalithi ephezuluamavalvu wevithamini, kodwana godu inokubuthelela okujulileko kwezobuchwepheshe kanye nezisombululo ezivuthiweko emkhakheni weamavalvu wesango, amavalvu wokuhlola, ivalvu yokukhupha umoya, njll. Kungakhathaliseki bona ngikuphi ukulawulwa kwamanzi okukutlhogako, singakunikela isekelo elipheleleko nelipheleleko le-valve. Nangabe unenhloso yokusebenzisana nofana ukubonisana ngokwethekhnikhi, sibawa uzizwe utjhaphulukile ukukhuluma nathi nanyana kunini.
