Iivalvu zizinto ezibaluleke kakhulu kwiinkqubo eziluncedo. Aivalve yesango, njengoko igama libonisa, luhlobo lwesivalo esisetyenziselwa ukulawula ukuhamba kolwelo usebenzisa isango okanye ipleyiti. Olu hlobo lweivalveisetyenziselwa ikakhulu ukumisa ngokupheleleyo okanye ukuqalisa ukuhamba kwaye ayisetyenziselwa ukulawula umthamo wokuhamba ngaphandle kokuba yenzelwe ukwenza njalo.
Egqibeleleabavelisi beevalvu zoshishinolandela imigangatho engqongqo ngelixa usenza eziiivalveukuqinisekisa umgangatho, ukuqina, kunye nokusebenza. Naluphi na uhlobo lomgangatho ophantsi lunokukhokelela kumonakalo ongafunwayo kunye nelahleko yezoqoqosho. Ukusebenza kunye nokulula kokusebenza zizinto ezimbini ezibaluleke kakhulu xa ukhetha i-valve kwi-plethora ye-vales ekhoyo kwimarike.
Ivalve yesluyisiubizwa nguivalve yesango, jonga ukuze ufumane ulwazi oluninzi malunga nabo.
Intoniis AIvalve yeSango?
Umthombo:Ivalve ye-TWS
A ivalve yesangoluhlobo lwevalvu yokwahlula esetyenziselwa ukulawula ukuhamba kolwelo kwinkqubo yoshishino. Ai-sluiceibhekisa kumjelo owenziweyo oncediswa lisango lokulawula ukuhamba kwamanzi. Iivalve ze-sluice okanyeiivalvu zesango loshishinoikakhulu zisetyenziselwa iinjongo zoshishino. Ubuchwephesha bayo obulula nobulula buyenza ibe yenye yezona zisetyenziswa kakhuluiivalvekumashishini ahlukeneyo. Ivalve isebenza ngokushukuma okanye ngokuphakamisa umqobo kwindlela yolwelo oluqukuqelayo.
Isetyenziswe ecaleni kombhobho kwindlela enye-i-directional okanye i-bi-directional flow. Xa ivuleke ngokupheleleyo, ayinikezeli ukuxhathisa kulwelo oluqukuqelayo, esesinye sezizathu ezibangela ukuba luthathwe lusebenza kakhulu. Ubume besango bunokuba buhambelana, kodwa kwiimeko ezininzi, igcinwe kwimilo ye-wedge. Wedgeiivalve zesangonceda udale i-sealant engcono xa ivaliwe njengoko ifaka uxinzelelo kwindawo yokutywina kwaye inikezela ukusebenza kokutywinwa okungcono.
A ivalve yesangoisebenza ngokujikelezisa ngesandla kwevili eliphathwa ngesandla, okanye isebenzisa umbane okanye i-pneumatic actuator.Ukujikeleziswa kwevili amaxesha amaninzi kunyusa isango, nto leyo elawula ukuhamba kolwelo okanye igesi ngaphakathi kwevalve. Ukuvula isango kunika umqobo omncinci wokuhamba kodwa ukugcina isiqingatha sesango sivulekile kunokubangela umonakalo njengoko ulwelo oluhambayo okanye igesi iya kwenza umthamo omkhulu woxinzelelo kwipleyiti. Ngaphandle kweiivalve zesango, iivalvu zeglowubhu zingasetyenziselwa ukulawula ukuhamba.
Ukusebenza
Nangona aivalve yesangookanye ivalve yesluice kulula ukuyisebenzisa, iqulathe amacandelo amaninzi adityanisiweyo ukuze asebenze ngokufanelekileyo. Olu hlobo lweivalveibandakanya umzimba, isango, isihlalo, ibhonethi, kwaye kwezinye iimeko, i-actuator eyenza ukuhambahamba.Iivalvu zesangoinokuveliswa kusetyenziswa izinto ezahlukeneyo; kunjalo, steel stainless yeyona nto ikhethwayo ukususela impahla ukumelana ngakumbi utshintsho lobushushu okanye uxinzelelo. Iinxalenye ezahlukeneyo zevalve yesango zichazwe ngezantsi.
ISango
Ifumaneka kwiindidi ezahlukeneyo zoyilo, isango liyinxalenye ephambili yevalve yesango. Eyona nkalo yoyilo lwayo kukutywinwa kwayo kwizicelo ezithile. Aivalve yesangoingahlelwa njengevalve ehambelanayo okanye emise okwe wedge esekelwe kuhlobo lwesango. Eyangaphambili inokwahlulwa kwakhona ibe ngamasango e-slab, amasango esilayidi ahambelanayo, kunye namasango akhulayo ahambelanayo.
Izihlalo
A ivalve yesangoinezihlalo ezibini eziqinisekisa ukutywinwa kunye nesango. Ezi zihlalo zinokudityaniswa ngaphakathi kumzimba wevalvu, okanye zinokubakho ngendlela yeringi yokuhlala. Le yokugqibela iculwa okanye icinezelwe kwindawo yayo kwaye emva koko itywinwe kwaye idityaniswe kumzimba wevalvu. Kwiimeko apho i-valve ixhomekeke kumaqondo okushisa aphezulu, izihlalo zokuhlala zikhethwa, njengoko zivumela ukuhluka okungaphezulu kokuyila.
Isiqu
Isango ngoivalve yesangoithotywe okanye inyuswe xa ijikeleza kwindlela enemisonto. Oku kunokwenzeka ngevili lezandla okanye i-actuator. Iqhutyweivalve yesangoinokulawulwa kude. Ngokuxhomekeke kuhlobo lwenyathelo, iivalve yesangozingahlelwa ngokwezintlu ezinyukayo nezinganyukiyo. Eyokuqala igxininiswe kwisango, ngelixa i-actuator igxininiswe kwaye ifakwe kwisango.
Iibhonethi
Iibhonethi ngamalungu evalvu aqinisekisa ukutywinwa okukhuselekileyo kwendlela. Isenokuba ibholitiwe okanye ikrwelwe kumzimba wevalvu ukuze ikwazi ukususwa ukuze itshintshwe okanye igcinwe. Ngokusekwe kwisicelo, iindidi ngeendidi zeebhonethi zevalvu zibandakanya iibhonethi zebholiti, iibhonethi ze-screw-in, iibhonethi zomanyano, kunye neebhonethi zokutywinwa koxinzelelo.
Usetyenziso
Iivalvu zesangookanye iivalvu zesluice zinezicelo ezininzi kumashishini ahlukeneyo kwaye zineendlela ezahlukeneyo zokusetyenziswa ekulawuleni ulwelo, igesi, kunye nokuhamba komoya. Kwiimeko ezinzima zokusingqongileyo ezifana nobushushu obuphezulu okanye iindawo ezinoxinzelelo oluphezulu kumashishini e-petrochemical, iivalve zesango zisixhobo sokuhamba. Kwiimeko ezinjalo, izinto eziphathekayo kunye nohlobo lwe-valve ludlala indima ebalulekileyo ekusebenzeni kunye nokusebenza kakuhle kwe-valve.
Iivalve zesango nazo zifumana ukusetyenziswa kwazo kwiinkqubo zokhuseleko lomlilo, apho aivalve yesango eneflangedisetyenziswa ngokuqhelekileyo.Iivalvu zesango lesiqu esinganyukiyozisetyenziswa kwiinqanawa okanye ngaphantsi komhlaba kwiindawo apho indawo ethe nkqo ilinganiselwe.
Iintlobo zeIivalvu zeSango
Umthombo:Ivalve ye-TWS
I-Parallel kunye ne-Wedge-MiloIivalvu zeSango
Njengoko igama libonisa, iivalvu zesango lesilayidi ezinxuseneyo zinesango elisicaba, elinobuso obunxuseneyo elifakwe phakathi kwezihlalo ezibini ezinxuseneyo. Kwelinye icala, wedgeiivalve zesangoibe necango efana necango. Oku kuneembambo kumacala omabini kwaye ikhokelwa kwindawo yokubeka kwiindawo zokubeka kumzimba wesango. Ezi zikhokelo ze-wedge zinceda ukudlulisa imithwalo ye-axial ebekwe ngumbindi ukuya kumzimba wevalve, yenza intshukumo ye-low-friction, kwaye ithintele ukujikeleza kwe-wedge ngelixa uhamba phakathi kweendawo ezivaliweyo.
Isiqu esinyukayo kunye neeValufa zeSango leStem ezinganyukiyo
Umahluko ophambili phakathi kwezi ntlobo zimbini zeiivalve zesangokukuba mhlawumbi zilungisiwe (ziyanyuka) okanye zifakwe imisonto (azinyuki). Kwiiivalvu zesango lesiqu esinyukayo, isiqu esijikelezayo siphakama ngelixa i-valve ivula. Nangona kunjalo, olu hlobo lwevalve alukhethwanga apho isithuba silinganiselwe okanye ufakelo luphantsi komhlaba.
IMetal ihleli kwaye ihleli iivalufa zeSango ezizinzileyo
Zombini ezi ziinkozoiivalve zesango. Kwiiivalve zentsimbi ezihleli, le wedge ishelela ngasemseleniivalve yesangoumzimba kwaye inokubamba izinto eziqinileyo ezinolwelo. Ngoko ke,iivalvu ezihleli phantsizikhethwayo apho kufuneka kuvalwe ngokungqongqo, njengakwiinkqubo zokuhambisa amanzi.
In iivalvu ezihleli phantsi, i-wedge ivalwe ngaphakathi kwe-elastomer eqinisekisa ukutywinwa okuqinileyo. Ukuhlaliswa kwenzeka phakathi komzimba wevalve kunye ne wedge kwaye ayifuni groove njengakwimeko yevalve yesango ehleliyo yentsimbi. Ekubeni ezi zivalo zigqunywe nge-elastomer okanye i-resilient material, zinika umgangatho ophezulu wokukhusela ukubola.
Amazwi Okugqibela
Iivalve ze-sluice kunyeiivalve zesangongamagama ahlukeneyo ohlobo olufanayo lwesivalo. Olu lolona hlobo luqhelekileyo lweiivalvu zoshishinoesebenzayo. Njengoko iivalve zesango zenziwe kusetyenziswa izinto ezahlukeneyo kwaye zineentlobo ezininzi, uhlobo lwevalve kufuneka lukhethwe ngononophelo kwizicelo ezithile.
Umgangatho olungileyo kunye nokusebenza kakuhleiivalvenjengazoIvalve ye-TWSlutyalo-mali olukhulu njengoko lufuna ulondolozo oluncinci ekuhambeni kwexesha, olunokugcina imali eninzi. QhagamshelanaIvalve Ivalve ye-TWSnamhlanje kwiivalvu ezigqwesileyo kwiklasi.
