Luluphi uhlobo loxinzelelo lwe-valve yebhola?

Njengecandelo lolawulo oluphambili kwinkqubo ye-piholip yemizi-mveliso,I-valves yebholaYiba nolwahluko olubalulekileyo kudidi loxinzelelo ngenxa yeentlobo zolwakhiwo, izixhobo, kunye neendlela zokuqhuba. Banokwahlulwa ngokwamanqanaba amathathu alandelayo:

1. Uluhlu loxinzelelo lweevalva eziqhelekileyo

I-valve eqhelekileyo ichitha i-valves isebenzisa i-vardation okanye ekwakhiweni kwebhola eqinileyo, kunye noxinzelelo olujolise phakathi kwe-0.6-50mpa. Umzekelo, uxinzelelo oluthile lwensimbi yekhabhoniI-valves yebholaInokufikelela kwi-1.0-64MPA, ilungele imithombo yeendaba njengamanzi, i-AID, neGalo yendalo; Uxinzelelo oluthile lweValve yeBhola yeBhola yeBhola yeBhola yeBhola ye-1.6-6.4MPA, kwaye ilungele amaqondo obushushu asusela kwi--20 ℃ ukuya kwi-350 ℃. Inokuphatha amanzi, ioyile, igesi, kunye nolwelo oluphambili; Uxinzelelo olusebenzayo lwe-vhloumatic yebhola ye-upvc plve i-0.6-1.0mpa, efanelekileyo kwiimeko zokunganyangeki, ezicocekileyo nezinganetyhefu.

2. Uluhlu loxinzelelo lwe-valve yebhola ePhakamileyo

I-vils yebhola ePhakamileyo yenzelwe iimeko zokusebenza ezigqithisileyo, ngoluhlu lwengcinezelo ye-1.6-50MPA (ehambelana namanqanaba e-150lb-3000b). Umzekelo, i-valves yebhola ekhatywayo yentsimbi yentsimbi yenziwa nge-304/316 yentsimbi yentsimbi, kunye ne-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm ye-0.5mm yenziwa kwitekisi yokutywina ngetekhnoloji yokutywina. Banokumelana namaqondo obushushu aphezulu angama-600 ℃ kwaye balungele iinkqubo zoxinzelelo lwempindezelo efana nePetroleum Reflinel, Ubunjineli bamachiza, kunye namandla; I-upox yoxinzelelo lwe-valve ye-pneumatic ye-pn1.6-6.4MPA, ilungele ulawulo olujikelezayo kunye noxinzelelo oluphezulu kunye neenkqubo zokugcwalisa.

3. Uluhlu loxinzelelo lweeValves zeBhola phantsi kweemeko ezikhethekileyo zokusebenza

Kwimithombo yeendaba ezikhethekileyo okanye imeko, uluhlu loxinzelelo lweI-valves yebholakufuneka yenziwe ngakumbi. Umzekelo, uxinzelelo olusebenzayo lwe-valve ze-pneumatic yebakala li-0.4-0.7MPA (Uluhlu loxinzelelo PN0.1-10Ma), elungele imizi-mveliso enezixhobo eziphezulu ezinjengokutya neyeza; Ixabiso lezelo eliphantsi lobushushu, yamkela intamo ende yoyilo lokuthintela ukusilela kokutywina kwe-valve phantsi kweemeko zobushushu obuphantsi, kwaye uluhlu loxinzelelo lunokugubungela imeko yobushushu obuncinci; I-varve yebhola ye-incachet ithintela i-crystalment ye-right edlulayo ngokudlulisela ijaci, kwaye ilungele iimeko zomsebenzi apho i-Medium ihamba khona kwikristali.

Iingcebiso zokhetho

Xa ukhetha ivalve yebhola, kuyimfuneko ukuqwalasela iimpawu zenqanaba eliphakathi, nengcinezelo, kunye nenqanaba lobushushu. Phantsi kweemeko eziqhelekileyo zokusebenza, intsimbi yekharbon okanye ivali yebhola ezintathu zinokukhethwa; I-valve yebhola enesitayile esiphezulu sentsimbi kufuneka inikwe indawo ephambili kwiindawo zoxinzelelo oluphezulu; Uyilo olufanelekileyo luyafuneka kwiimeko ezikhethekileyo zokusebenza, ezinje ngee vallo zebhola eziphantsi okanye i-ivacket yebhola yentsholongwane.
