Ivalve yeCryogenic yivalve yenjongo ekhethekileyo enokusetyenziswa kwezi mveliso zilandelayo: iimveliso ezisetyenziselwa ukugcina nokuthutha iigesi ezahlukeneyo, xa ezi gesi zipholile kumaqondo obushushu aphantsi (umzekelo, igesi yendalo, ioksijini, initrogen, ihydrogen kunye nehelium. Inland Kwaye uthutho lwaselwandle kunye nokugcinwa kwesiza kunye nokungabikho kwendawo kwezi gesi zenza inxalenye enkulu yengeniso epheleleyo yemarike yevalve ye-cryogenic.
Ingxelo luhlalutyo olubanzi kunye nophando kwixesha elidlulileyo kunye nesantya sangoku sokukhula kwemarike yevalufa ye-cryogenic. Ingxelo yinkcazo enzulu kunye neyobuchule kwimarike yevalve ye-cryogenic, kwaye inecandelo elicacileyo lommandla wemarike ukuphucula ukucaca.
Kwiminyaka yakutshanje, ngenxa yokwanda kokufunxa kwerhasi yendalo enyibilikisiweyo kwizicelo ezininzi zemizi-mveliso, imfuno yeevalvu ze-cryogenic kuwo wonke amandla kunye neshishini lamandla liye landa kakhulu. Ngexesha loqikelelo, imakethi iya kuxhamla kukukhula okuqhubekayo kothotho lwezicelo zerhasi yemizi-mveliso. Kwiminyaka embalwa edlulileyo, ihlabathi liye labona ukwanda okumangalisayo kwinani lezityalo zemveliso ezivelisa iigesi zemizi-mveliso ezifana nenitrogen, ioksijini, i-helium, iargon kunye necarbon dioxide. Ehlabathini lonke, inani lemizi-mveliso yeegesi zemizi-mveliso liyakhula. Ezi zinto zikwalindeleke ukuba zikhuthaze kakhulu imfuno yehlabathi yeevalvu ezahlukeneyo ze-cryogenic, ngaloo ndlela ziqhuba imarike yehlabathi.
Nangona kunjalo, ukuveliswa kunye nokuthengiswa kweevalve ze-cryogenic kufuneka zihambelane nomgangatho ongqongqo kunye nemigangatho enxulumene nokhuseleko, enokunyusa kakhulu iindleko ezisisiseko zeevalve ze-cryogenic. Nangona kunjalo, kwiminyaka embalwa edlulileyo, intengiso iye yakhuphisana kakhulu njengoko iinkampani zifunda iindlela zokubonelela abathengi ngeemveliso zoqoqosho. Olu xinzelelo lunokuthi luchaphazele kakubi ingeniso yeenkampani ezisebenza kwimarike yevalve ye-cryogenic yehlabathi ukuya kumlinganiselo othile.
Ingxelo yahlulahlule imakethi yevalve ye-cryogenic yehlabathi esekwe kwigesi yendalo, ishishini lokusetyenziswa kokuphela, uhlobo lwevalvu, usetyenziso, kunye nendawo yejografi. Ngokusekwe kwigesi yendalo, imakethi yahlulwe yaziinitrogen, igesi yendalo, ioksijini, ihydrogen kunye nehelium. Ngokweentlobo zeevalvu ze-cryogenic ezifumaneka kwintengiso yehlabathi, ingxelo igubungela iivalve zebhabhathane, iivalvu zebhola, iivalve zeglowubhu kunye neevalvu zesango. Ngokusekwe kumzi-mveliso wokusetyenziswa kokuphela, ingxelo yahlulahlula imakethi yevalve ye-cryogenic yehlabathi ibe ngamandla kunye nombane, ukutya neziselo, kunye neekhemikhali. Ngokwesicelo, imarike yeetanki ze-cryogenic, iitanki ze-cryogenic, oololiwe begesi kunye nemibhobho ifundwe.
Kuqikelelwa ukuba ulwahlulo lwerhasi yendalo ngohlobo lwerhasi luya kunceda imakethi yevalve ye-cryogenic yehlabathi ifumane isabelo esona sikhulu sengeniso yayo. Ngokumalunga neentlobo zemveliso, inxalenye yevalve yebhola iya kuphendula ngesabelo esiphambili sengeniso. Ngokumalunga nokusetyenziswa kokuphela, amacandelo amandla kunye namandla aya kuqhubeka ukuba ngabathengi abakhulu. Ngokwembono yejografi, imakethi ye-Asia-Pacific kulindeleke ukuba ilawule ingeniso yehlabathi ngenxa yokonyuka okukhulu kwemfuno ye-LNG kunye neekhemikhali ezininzi kuqoqosho olusakhulayo olukhulayo (olufana neIndiya neTshayina).
Ingxelo ikwabonelela ngohlalutyo oluneenkcukacha lokuma komhlaba okhuphisanayo kwimakethi yehlabathi ye-cryogenic valve kwaye ihlalutya abanye bababoneleli abakhulu kwimarike. UParker, u-Emerson, uSchlumberger, uFlowserve kunye neQela le-Weir ngababoneleli abakhokelayo kwimarike yevalve ye-cryogenic yehlabathi.
Uphando lwe-TMR ngumboneleli ophambili wophando lwemalike olulungiselelweyo kunye neenkonzo zokucebisa kumaqumrhu oshishino anomdla wokuphumelela kwimekobume yezoqoqosho yanamhlanje ekhulayo. Ngeqela labahlalutyi abanamava, abazinikeleyo nabanamandla, sichaza ngokutsha indlela abathengi bethu abaqhuba ngayo ishishini ngokubabonelela ngeengxelo zophando ezigunyazisiweyo nezithembekileyo, ngokuhambelana neendlela zamva nje kunye nentsingiselo yemarike.
