Yintoni iValve yeSango? Inkcazo, ulwakhiwo, iintlobo, kunye nokuqonda kwababoneleli

Intshayelelo

Ivalvu yesangolicandelo elibalulekileyo kwiinkqubo zemibhobho yemizi-mveliso, ezenzelwe ukulawula ukuhamba kwamanzi. Zisetyenziswa kakhulu kumashishini okubonelela ngamanzi, ioyile negesi, kunye neekhemikhali, iivalvu zesango zaziwa ngokuthembeka kwazo nokusebenza ngokulula. Kweli nqaku, siza kuhlola inkcazo, ulwakhiwo, imisebenzi, ulwahlulo, izixhobo, iindlela zoqhagamshelo, kunye namaxabiso eevalvu zesango, ngelixa sithelekisa amazwe amakhulu okuvelisa afana neTshayina, i-USA, neJamani.

Yintoni iValve yeSango?

A ivalvu yesangoyivalvu ehamba ngomgca othe tyaba okanye omile okwesikwere ukuqala okanye ukumisa ukuhamba kolwelo. Xa ivuliwe ngokupheleleyo, ivumela ukuhamba okungenamkhawulo, kwaye xa ivaliwe, inika isitywino esiqinileyo. Uyilo lwayo olulula luyenza ilungele ukusetyenziswa kokuvula/ukuvala endaweni yokulawula ukuhamba kolwelo.

Ulwakhiwo lweValve yeSango

Ivalvu yesango eqhelekileyo iquka:

1. Umzimba: Igcina izinto zangaphakathi kwaye iqhagamshela kumbhobho.

2. Isango/Iweji: Idiski eshukumayo ethintela okanye evumela ukuhamba kwamanzi.

3. Isiqu: Iqhagamshela ivili lesandla okanye i-actuator kwisango.

4. Ibhonethi: Igquma isiqu nomzimba, iqinisekisa ukusebenza okungenamanzi.

5. Izihlalo: Iindawo ezivalwa kuzo isango xa livaliwe.

Imisebenzi yeeValvu zeSango

- Ulawulo Lokuvula/Ukucima: Ngokuyintloko isetyenziselwa ukuvula okanye ukuvala ngokupheleleyo imibhobho.

- Ukumelana nokuhamba okuphantsi: Uxinzelelo oluncinci xa luvuliwe ngokupheleleyo.

- Ukuhamba kweendlela ezimbini: Ifanelekile kwizicelo ezifuna ukuhambahamba kuzo zombini iindlela.

Ulwahlulo lweeValve zeSango

Iivalvu zesango zihlulwe ngokwezi:

1. Uyilo lweSango:

–I-Wedge Gate Valve: Kwiinkqubo ezinoxinzelelo oluphezulu.

–Ivalvu yeSango leSlide ehambelanayo: Ilungele umphunga okanye igesi.

2. Uhlobo lwesiqu:

–Isiqu Esinyukayo: Ukuhamba kwesiqu okubonakalayo kubonisa indawo yevalvu.

–Isiqu Esingavukiyo: Uyilo oluncinci lwendawo elinganiselweyo.

Izinto eziqhelekileyo

Ukukhethwa kwezinto eziphathekayo kuchaphazela ukuqina kunye nokusetyenziswa kwazo:

- Jula i-ayini: Ixabiso elifanelekileyo kwiinkqubo zamanzi ezinoxinzelelo oluphantsi.

- Yenziwe ngentsimbi eshayinayo: Iyamelana nokugqwala kwiindawo ezineekhemikhali okanye zaselwandle.

- Intsimbi yeCarbon: Ifanelekile kwiipayipi zeoyile/zegesi ezishushu kakhulu.

- Ibronzi: Isetyenziswa kwiinkqubo zaselwandle kunye ne-HVAC.

Iindlela zoQhagamshelo

Iivalvu zesango ziqhagamshelwa kwimibhobho ngokusebenzisa:

1. Iziphelo eziFlanged: Kwiinkqubo zoshishino ezinoxinzelelo oluphezulu.

2. Iziphelo Ezinemisonto: Ixhaphakile kwiipayipi ezincinci.

3. Iziphelo eziWelded: Ibonelela ngokusebenza okukhusela ukuvuza kwizicelo ezibalulekileyo.

Izinto ezibangela amaxabiso eValve yeSango

Iixabisoivalvu yesango ixhomekeke kwi:

- Ubungakanani kunye novavanyo loxinzeleloIivalvu ezinkulu okanye iiklasi zoxinzelelo oluphezulu zibiza kakhulu.

- Izinto eziphathekayoIivalvu zentsimbi engatyiwayo zibiza kakhulu kunezentsimbi ephosiweyo.

- Uphawu kunye noMboneleli: Abavelisi abaziwayo banokuhlawulisa iprimiyamu.

Ngokomyinge, amaxabiso aqala kwiI-$5 kwiivalvu ezincinci zesinyithiukuyaI-$1,000+ kwiivalvu ezinkulu zentsimbi engagqwaliyo.

Amazwe Aphambili Emveliso: I-China vs. Ababoneleli Behlabathi

1. iTshayina:

– Ilawula imveliso yehlabathi ngeisebenza kakuhle emaliniizisombululo.

- Izindlu ezininziiifektrikwayeabavelisienikezela ngeeodolo ezinkulu.

– Ukhuphiswanoamaxabisongaphandle kokubeka emngciphekweni umgangatho (umz., imigangatho ye-ASTM/API).

2. I-USA kunye neJamani:

– Yaziwa ngeevalvu ezichanekileyo kodwa ngexabiso eliphezulu.

– Ikhethwa kakhulu kumashishini akhethekileyo afana nenyukliya okanye i-aerospace.

3. Indiya :

– Ivela njengenye indlela enoqoqosho oluphantsi kuneTshayina.

Kutheni Ukhetha Ababoneleli baseTshayina

- Ii-MOQ ezisezantsi: Ilungele amashishini amancinci ukuya kwaphakathi.

- Ukwenziwa ngokwezifiso: Iifektri ezininzi **zeefektri** zibonelela ngoyilo olulungiselelwe wena.

- Ukuhanjiswa Okukhawulezayo: Iinethiwekhi zothutho eziqinileyo.

Isiphelo
