I-valve ye-ball yokulondolozwa: ukuyila kunye nesicelo

Iigravves zebhola zisebenza njengemigodi yokumisa kwiipayipi zangaphandle (iipetroli zepetroli kunye neoli, iipayipi zendlela yokusebenza, iipayipi kwimichiza ephambukayo kunye namashishini abungozi bomlilo, njl.). Enye yeentlobo zebhola yebhola ibhola yebhola yokulumala.

Isetyenziswa njengefowuni yokukhiya ukwenzela ukukhusela ngokupheleleyo ukuhamba komjikelezo ophakathi kwipayipi. Indawo enjalo ingaba yioli kunye nemveliso yayo, amanzi, igesi yendalo, umoya, iimveliso zotywala, nezinye iindaba ezigwenxa.

Olu hlobo lwe-crane lubonakaliswe ngento yokuba idibaniswe kumbhobho ngokuluthwa. I-valve yebhola ye-welding ayinayo iindawo ezinokutsha (ama-flanges, ama-couplings, njl.), Kwaye oku kuqinisekisa ukuxinwa kokuxininisa nokunciphisa ukuvuza kwamalungu.

Ukwahlula

Iiplavini zebhola zokudwelisa zihlelwa ngohlobo lwe-drive:

• Umqulu;
• Ukuba nombane wombane (okwenziwa ngumyalelo okhethekileyo ukuqwalasela iimpawu zepayipi);
• Umqulu kunye nomncinci;
• Ngokuqhutshwa kwe-pneumatic drive (eyenziwe ngumyalelo okhethekileyo ukuqwalasela iimpawu zepayipi).

Ngokuqhelekileyo, i-valve yebhola yesandla esinezantsi isetyenziswe ubuncinane obukhulu bemihlathi, kunye nexinzelelo eliphantsi okanye eliphakathi kwipayipi. Ukuba uxinzelelo lwepayipi lungaphezulu komyinge, kwaye iipayipi ngokwazo zikhulu okanye ziphakathi, kulungile ukusebenzisa i-crane ene-electric drive okanye i-crane ene-pneumatic drive.

Kwakhona, i-valve yebhola ye-welding ingaba yi-full-bore kwaye ingaphelelanga (ihlelwe nguhlobo lwesigcawu).

Ukuveliswa kunye nokwakhiwa kwevolve yebhola

Amacandelo omzimba wamagobha ebhola ayenziwe ngokususa (ukwenzela ukuba uxhulumano luqinile kwaye lunokwethenjelwa). Ibhola elihamba ngokukhululekile linamathele nge-PTFE saddles.

Kwimveliso, iteknoloji yasekuqaleni isetyenziswa. Isici esinqununu samacebo yintsimbi, i-casing ehlukileyo. Ngethuba lemveliso, indlela yokukhiya ibanjwe kuqala, ize ifakwe kwizindlu. Iimbumba zinyanzeliswa.

Isiphumo sisakhiwo esingenakuhlukana esingafuni ukugcinwa.

I-valve yebhodi yensimbi edibeneyo inokwakhiwa okwangaphakathi okwangaphakathi. Xa kunxiba, lo mdwebo uhlawulela inkqubo ngokwayo. Oku kuququzelelwe ngeebhola ezihamba ngehhala, ezikhoyo phakathi kwamanzi ane-sealant. Ukuba enye inxalenye igqoke, intwasahlobo ingenakululwa kwaye isakhiwo sonke sinoxinano oluqinileyo. Oku kuqinisekisa ukubambelela ixesha elide.

Ukusebenza nokugcinwa

1. I-valve yebhola yokwelusa iya kusebenza kwiqondo lokushisa elingekho ngaphantsi kwama-30 ^о С.

2. Uxinzelelo kumbhobho ungabakho ama-1.6 / 2.5 / 4 ama-megapascals.

Umgangatho ojikelezayo kufuneka ube nobushushu obufanelekileyo: uluhlu luvela -35 ukuya ku- +180 ^o C.

Ukugcinwa rhoqo kunye nokugcinwa kweendleko zalezi zixhobo akudingeki. Ungongeza kuphela itywina ngentonga yakho. Ukuphuhliswa koyilo alungiseleli umsebenzi wokulungisa okanye ukutshintshwa kwamalungu ngexesha lokusetyenziswa.

Iingenelelo kunye nokungalunganga kweemvalo zebhola zokulumala

Iiplathi:

• Iqondo eliphantsi;
• Iindleko eziphantsi;
• Ithempu ivula ngokukhawuleza kwaye kulula;
• Xa usebenzisa itompu, akukho ndawo ehlala kuyo kwindawo apho amanzi aphuma khona;
• Ukwakhiwa okuzinzileyo, okuthembekileyo nokulula;
• Ukugqithiswa kwe-Hermetic yokuhamba kwamanzi;
• Le ngqayi ifakwe kwiindawo eziphambili kunye ezinzima zepayipi;
• Akukho sondlo efunekayo.

Iingxaki:

• Lungiswa;
• I-crane inokufakwa kuphela kwaye ishintshwe ngomsebenzi wokumisela;
• Ingozi yempembelelo ye-hydraulic xa i-crane ivula ngokukhawuleza;
• Ukungahambi kakuhle kusetyenziso ngenxa yesibindi eside se-crane yokuvalwa (xa usebenza kwiimeko ezinzima).
