Uhlobo oluthe nkqo Ivalufa yeSiqhwithi
Ingcaciso yeMveliso
Ivalve yesivunguvungu yivalve yohlobo lwe-flap engabuyisiyo esetyenziselwa ukukhupha amanzi amdaka. Idityaniswe kumbhobho womhlaba kwelinye icala kwaye elinye icala lisecaleni leenqanawa ukuze ugutyulo lube ngaphezulu. Ngoko inokugqithwa kuphela ngexesha le-drydocks.
Ngaphakathi kweflap yevalve kukho encanyathiselwe kwi-counterweight, kunye nebhloko yokutshixa. Ibhloko yokutshixa sisiqwenga sevalve elawulwa kwaye iqhutywe livili lesandla sangaphandle okanye i-actuator. Injongo yebhloko yokutshixa kukubamba i-flap endaweni ekugqibeleni ithintele ukuhamba kolwelo.
Nje ukuba uqukuqelo luqale, umqhubi kufuneka akhethe ukuba uyayivula na ibhloko yokutshixa, okanye ayigcine ivaliwe. Ukuba ibhloko yokutshixa ivaliwe, ulwelo luya kuhlala ngaphandle kwevalve. Ukuba ibhloko yokutshixa ivulwa ngumsebenzi, ulwelo lunokuhamba ngokukhululekileyo kwiflap. Uxinzelelo lolwelo luya kukhulula i-flap, ivumele ukuba ihambe ngokuphuma kwindawo enye. Xa ukuhamba kuyeka, i-flap iya kubuyela ngokuzenzekelayo kwindawo yayo evaliweyo.
Kungakhathaliseki ukuba ibhloko yokutshixa ikhona okanye ayikho, ukuba ukuhamba kuza ngokuphuma, ukuhamba ngasemva akuyi kukwazi ukungena kwi-valve ngenxa ye-counterweight. Olu phawu luyafana nelo lwevalvu yokutshekisha apho ukuphuma ngasemva kuthintelwe ukuze kungayingcolisi inkqubo. Xa isibambo sithotywa, ibhloko yokutshixa iya kuphinda ikhusele i-flap kwindawo yayo esondeleyo. I-flap ekhuselekileyo ihlukanisa umbhobho ukwenzela ukugcinwa ukuba kuyimfuneko
