Umgaqo kunye nokuhlelwa kweevalvu zokulawula

Ivalve yokulawula sisixhobo esiqhelekileyo sokulawula ukuhamba kwamanzi, esisetyenziswa kakhulu kumashishini, iikhemikhali, i-petroleum, amanzi okupompoza, igesi yendalo kunye nezinye iindawo. I-valve elawulayo isekelwe kumgaqo wolawulo loxinzelelo oluhlukeneyo, okwenza ukuhamba kwamanzi kufikelele kwixabiso elimiselweyo ngokulawula ukunyanzeliswa koxinzelelo oluphakathi. I-valve elawulayo inokutshintsha kwakhona iiparitha zenkqubo yokulawula ukuqonda ukulungelelaniswa kokuhamba, inqanaba le-liquid, ubushushu kunye nezinye iiparamitha, ukuze kuqatshelwe ulawulo oluzenzekelayo lwenkqubo.

Ulwahlulo lweevalvu zokulawula lunokwahlulwa lube ziindidi ezininzi ngokweemeko zokusebenza ezahlukeneyo, njengoko kubonisiwe ngezantsi:

1. I-valve yokulawula uxinzelelo: isetyenziselwa ukulungelelanisa uxinzelelo kwipayipi, esetyenziswa kakhulu kwishishini lemichiza, i-petroleum kunye nezinye iindawo.

I-valve yokulawula ukushisa kwe-2: ilungele ukulungiswa kweqondo lokushisa eliphakathi, eliqhelekileyo kwiinkqubo zamanzi ashushu, izifudumezi, njl.

3. Ivalve yokulawula inqanaba lolwelo: isetyenziselwa ukufikelela kulawulo lwenqanaba lolwelo kunye nolawulo, oluhlala lusetyenziswa kunyango lwamanzi, kushishino lweekhemikhali kunye neminye imimandla.

I-valve yokulawula ukuhamba kwe-4: ikakhulu isetyenziselwa ukulungelelanisa ukuhamba kombhobho, isetyenziswe ngokubanzi kwiikhemikhali, amayeza, ukutya kunye nezinye iindawo.

5. I-valve yokulawula i-Directional: isetyenziselwa ukulungisa indlela yokuhamba kwamanzi, ngokuqhelekileyo isetyenziselwa i-shunt kunye nokusebenza kwe-confluence.

Ngokweendlela ezahlukeneyo zolwakhiwo, iivalvu zokulawula zinokwahlulwa zibe zezi ntlobo zilandelayo:

1. Ivalve yokulawula uhlobo lwesango: yenziwe ngenkunzi yegusha eshukumayo kunye negasket. Xa inkunzi yegusha ihamba nge-axis perpendicular ukuya kwicala lokuhamba kwamanzi, indawo yomjelo inokutshintshwa, ngaloo ndlela iguqule ubungakanani bokuhamba.

2. Isilawuli sohlobo lwe-diaphragm: iqulethwe nge-diaphragm, isihlalo kunye nendlela yokuqhuba kunye nezinye izinto. Xa i-diaphragm iphantsi koxinzelelo oluphakathi, ingena kwisihlalo ukukhusela ukuvuza okuphakathi, ngaloo ndlela ifezekisa ulawulo lokuhamba.

I-valve yokulawula i-pneumatic ye-3: yenziwe nge-cylinder yegesi, i-valve yokulawula igesi kunye nendlela yokusebenza kunye nezinye izinto. I-piston kunye ne-disc zihlanjululwe ecaleni kwe-axis ngegalelo leempawu zoxinzelelo ezahlukeneyo ukufikelela kulawulo lokuhamba.

4. I-valve yokulawula umbane: yenziwe yi-motor, i-reducer, i-clutch, i-valve, isixhobo sokulawula kunye nezinye izinto. Ngokujikeleza isivalo sevalve yemoto, ukuhamba kungalungiswa.

Ngokubanzi, ivalve yokulawula kulawulo lwamashishini, ulawulo lwenkqubo kunye nokhuseleko kunye neminye imiba inoluhlu olubanzi lwezicelo, ezahlukeneyo zayo, ngokuthe ngcembe zibhekisa kubukrelekrele, i-automation, ukuphucula ukusebenza kakuhle kwemveliso yamashishini, ukunciphisa ungcoliseko lokusingqongileyo kunye nokukhusela ukhuseleko lwabasebenzi kunye neminye imiba. ukubaluleka okubalulekileyo.
