I-valves ibaluleke kakhulu kwiinkqubo zokusebenzisa. AI-Palve yesango, njengoko igama libonisa, luhlobo lwe-valve esetyenziselwa ukulawula ukuhamba kolwelo kusetyenziswa isango okanye iplate. Olu hlobo lweivalveIsetyenziselwa ukuyeka ngokupheleleyo okanye ukuqalisa ukuhamba kwaye ayisetyenziswanga ukulawula inani lokuhamba ngaphandle kokuba lenzelwe ngokukodwa.
EgqibeleleAbavelisi beVovieLandela imigangatho engqongqo ngelixa uvelisa eziivaliUkuqinisekisa umgangatho, ukuqina, kunye nokusebenza. Naluphi na uhlobo lomgangatho ophantsi onokukhokelela kumonakalo ongafunekiyo kunye nelahleko yezoqoqosho. Ukusebenza kakuhle kunye nokuSebenza okuKhawulezayo zizinto ezimbini ezibaluleke kakhulu xa ukhetha ivalve evela kwintengiso ekhoyo kwintengiso.
I-slice valveibizwa ngokubaI-Palve yesango, jonga ulwazi ngakumbi malunga nabo.
IntoniiaI-Palve yesango?
Umthombo:I-valve
A I-Palve yesangoLuhlobo lohlobo lwevalve yokuzodwa esetyenziselwa ukulawula ukuhamba kweembizi kwinkqubo yemveliso. AsliceIbhekisa kwijelo le-artitifibiation lincedisa ngesango lokulawula ukuhamba kwamanzi. I-slice valves okanyeI-valve yesangoisetyenziselwa ikakhulu kwiinjongo zemizi-mveliso. Indlela yayo elula kwaye elula yenza ukuba ibe yeyona nto isetyenzisiweyoivalikumashishini ahlukeneyo. I-Vhilo isebenza ngokuhamba nje okanye iphakamise isithintelo kwindlela yokuhamba kotywala.
Isetyenziswe ecaleni kombhobho kwi-treat-tick freeal okanye i-bi-bi-bi. Xa ivulekile ngokupheleleyo, akunzima ukumelana nokungabi nalwe lulwelo oluleka, olungenye yezizathu eziphambili zokuba kutheni kuthathwa njengempumelelo kakhulu. Ubume besango mhlawumbi bufanayo, kodwa kwiimeko ezininzi, zigcinwa kwimo yedrege. WedgeI-valves yesangoNceda Yenza itywina elingcono xa ivaliwe njengoko isebenza ingcinezelo kumhlaba wokutywina kwaye ibonelela ngentsebenzo engcono yokutywina.
A I-Palve yesangoisebenza ngokujikeleza kwevili levili, okanye isebenzisa isiqinisekiso sombane okanye se-pneumatic.Ukujikeleza kwevili inani lamaxesha lihambisa isango ukuya ezantsi, elilawula ukuhamba kolwelo okanye igesi ngaphakathi kwevalve. Ukuvula isango kubonelela ngokuphuma okuncinci kodwa ukugcina isango elivulekileyo kunokubangela umonakalo njengoko ulwelo oluhambayo okanye igesi iya kunika uxinzelelo olukhulu kwiplate. Ngaphandle kweI-valves yesangoI-globe valve zinokusetyenziselwa ukulawula ukuhamba.
Ukusebenza
Nangona iI-Palve yesangoOkanye okanye i-sliuich ivalve kulula ukusebenza, iqulathe amacandelo amaninzi alungelelaniswe kunye ukuze isebenze ngokufanelekileyo. Olu hlobo lweivalveUnomzimba, isango, isihlalo, i-bonnet, kwaye kwezinye iimeko, isenzo esisebenza nzima.I-valves yesangoinokwenziwa kusetyenziswa izixhobo ezahlukeneyo; Nangona kunjalo, intsimbi engenanto yeyona nto ikhethiweyo kuba izinto zinokunyangeka ngakumbi kutshintsho kwiqondo lobushushu okanye uxinzelelo. Iinxalenye ezahlukeneyo zevalve yesango zichazwe ngezantsi.
Isango
Ifumaneka kwiintlobo ezahlukeneyo zezinto, isango lelona candelo liphambili le-valve yesango. Eyona nto uyilo yoyilo lwayo sisikhundla sayo sokutywina kwezicelo ezithile. AI-Palve yesangoInokuhlelwa njenge-valve efanayo okanye ye-Wedge-ye-Wedge-ye-Wedge ngokusekwe kuhlobo lwesango. Owayengawahlulwa kuwo ngakumbi ukwahlulahlula-hlula-hlula amasango e-Slab, amasango esilayidi, kunye namasango akwandisiweyo.
Izihlalo
A I-Palve yesangoUnezitulo ezimbini eziqinisekisa ukutywinwa kunye nesango. Ezi zihlalo zinokudityaniswa ngaphakathi komzimba wevali, okanye zinokubakho ngohlobo lwendabuko lesihlalo. Elokugqibela inyibilikisiwe okanye icinezelwe kwisikhundla sayo kwaye emva koko itywinwe kwaye yatywina i-welved ukuya emzimbeni wevali. Kwiimeko apho iveli ixhomekeke kumaqondo obushushu aphezulu, amakhonkco esihlalo akhethwa, njengoko bevumela ukwahluka koyilo.
Isiqu
Isango elise-AI-Palve yesangoihlisiwe okanye iphakanyisiwe xa iqala ngenkqubo yesonga. Oku kungaqhubeka ngevili lencwadi okanye i-actutor. ItshintshiweI-Palve yesangoinokulawulwa kude. Kuxhomekeka kuhlobo lwenyathelo, iI-Palve yesangoinokuhlelwa ukuba ihlelwe ukuba inyuke kunye neziqu ezingezizo ezingezizo. Owayesengaphambi kwesango, ngelixa le yokugqibela ihleli kwi-artiator, inyibilikisiwe esangweni.
Iibhonasi
I-Bonnets ngamacandelo evalve aqinisekisa ukutywinwa okukhuselekileyo kwendinyana. Ibilisiwe okanye ikhutshiwe kumzimba wevali ukuze isuswe ukuze ithathelwe indawo okanye ilondolozo. Ngokusekwe kwisicelo, iintlobo ezahlukeneyo zebhobho ye-valve zibandakanya iibhoneli ze-bolt, isikhafu-kwi-bonnets, iibhonasi ze-Union, kunye noxinzelelo lweebhanti.
Izicelo
I-valves yesangookanye i-sliuice valves zinezicelo ezininzi kwimizi-mveliso eyahlukeneyo kwaye zinokusetyenziswa okwahlukileyo ekulawuleni ulawulo, igesi, kunye ne-airflow. Kwiimeko ezinzima zokuziphatha rhabaxa ezifana nobushushu obuphezulu okanye iindawo zoxinzelelo oluphezulu kumashishini e-Petrochemical Mveliso, i-valves yesango sisixhobo esiya kwisixhobo. Kwiimeko ezinjalo, izinto ezibonakalayo kunye nohlobo lwevalve zidlale indima ebalulekileyo kwintsebenzo kunye nokusebenza kwe-valve.
I-vilve zesango ikwafumana isebenzisa ukusebenzisa kwabo iinkqubo zokhuseleko lomlilo, apho aI-valve yesangoisetyenziswa rhoqo.I-valves yesango le-stemzisetyenziswa kwiinqanawa okanye ngaphantsi komhlaba kwiindawo apho indawo ethe nkqo inomda.
Iintlobo zeI-valves yesango
Umthombo:I-valve
Pharallel kunye ne-Wedge-imileI-valves yesango
Njengoko igama libonisa i-valves yesango le-slides linesango elineflethi, isango elinenkunkuma elixhonywe phakathi kwezihlalo ezimbini ezifanayo. Kwelinye icala, wedgeI-valves yesangoyiba ne-wedge-tenment yesango. Oku kube ziimbambo kumacala omabini kwaye zikhokelwa sisikhundla ngamagqabantshintshi esangweni. Ezi zikhokelo ze-Wedge zinceda ukuhambisa imithwalo ye-axial eshiyiweyo yibhunga leValve, elenzeni intshukumo ephantsi, kwaye kuthintele ukujikeleza kwe-odge ngelixa ihamba phakathi kwezikhundla ezivaliweyo.
Ukunyuka kwesiqu kunye ne-stem yesango le-Stem
Umahluko omkhulu phakathi kwezi ntlobo zimbini zeI-valves yesangoNgaba zilungisiwe (ziyaphakama) okanye zikhutshiwe (ezingonakalisi). NgaphakathiI-valves yesango, isiqu esijikelezayo senyuka ngelixa ivalve ivula. Nangona kunjalo, olu hlobo lwevali alukhethwa apho indawo inomda okanye ufakelo lungaphantsi komhlaba.
Intsimbi ehleli kunye ne-vallous yesango
Zombini ezi zi-WedgeI-valves yesango. Ngaphakathii-valve yentsimbi, i-Wedge Slide ukuya kwi-groove kwiI-Palve yesangoumzimba kwaye unokutyikitya iinyibilikisi ukuba ulwelo lubekhona. Ngenxa yoko,I-valves eyahlukileyobakhetha apho kufanelekileyo ukuthotywa kuyafuneka, njengeenkqubo zokuhambisa amanzi.
In I-valves eyahlukileyo, i-Wedge ifakwe ngaphakathi kwi-elastomer eqinisekisa itywina eliqinileyo. Indawo yokuhlala yenzeka phakathi kwebhulukhwe yevalve kunye ne-wedge kwaye ngenxa yoko ayinyanzelekanga ukuba ibe yi-Groove njengakwimeko ye-valve yentsimbi edanisiweyo. Ukusukela ezi valves zidibene ne-Elastomer okanye iZinto zokuhlala, zibonelela ngesidanga esiphezulu sokukhusela isiseko.
Amagama okugqibela
I-slice valves kunyeI-valves yesangongamagama ahlukeneyo ngohlobo olufanayo lwevalve. Olu luhlobo oluqhelekileyo lweI-valves yemizi-mvelisoisetyenzisiwe. Njengoko ii-valve zenziwe zisebenzisa izixhobo ezahlukeneyo kwaye zineendidi ezininzi, uhlobo lwevalve kufuneka lukhethwe ngononophelo kwizicelo ezithile.
Umgangatho olungileyo kunye nempumeleloivaliNjengaleI-valveNgaba utyalomali olukhulu njengoko lufuna ulondolozo oluncinci ekuhambeni kwexesha, olunokusindisa imali eninzi. UqhagamsheloIvalve I-valveNamhlanje kwiiValves-ezibalaseleyo.
