Izicelo zeValves zebhabhathane kunye neevalva zesango phantsi kweemeko ezahlukeneyo zokusebenza

I-valves yesangokwayeI-Butterfly Valveszisetyenziswa njengokutshintsha ukulawula inqanaba lokuhamba kwindawo yokusebenzisa umbhobho. Ewe kunjalo, kusekho iindlela kwinkqubo yokhetho yamabhabhathane nakwiivalvestop.

Kwinethiwekhi yokuhambisa amanzi, ukwenzela ukunciphisa ubunzulu besigqubuthelo somhlaba sepayiphu, ububanzi bombhobho omkhulu baxhotyisiwe, kodwa ukuba ubunzulu be-valve yesango iphezulu kunexabiso lebhabhathane. Njengokuba umda we-caraber of caliber, indawo nganye kufuneka ithathelwe ingqalelo kwimeko-yecala. Ngokwembono yokusetyenziswa kweminyaka elishumi edlulileyo, ukusilela kwebhotile yebhabhathane kungaphezulu kuneloI-Palve yesango, ke kufanelekile ukuba unikele ingqalelo yokwandisa uluhlu lwe-valve yesango ukuba iimeko ziyavuma.

Kwiminyaka yakutshanje, abavelisi bevala yendawo yokuhlala baphuhlise kwaye baxelise i-valves yesango elinethambile, ezineempawu ezilandelayo kune-valves okanye eziphindwe kabini zesango.

IivalveUmzimba kunye ne-bonnet ye-valve yesango elithambileyo yesango iphoswa ngendlela yokuchaneka kwendlela yokuchaneka, ekwakhiweyo ngexesha, kwaye ayisebenzisi i-rings, kwaye ayisebenzisi izinyithi zobhedu.

Akukho mngxunya ezantsi kweI-tyveve yesango elithambileyo, akukho kuqokelelwa kwe-slag, kunye nenqanaba lokusilela kweI-Palve yesangoUkuvula nokuvala kuphantsi.

Iplate yetywina elithambileyo le-valve i-valve iyunifomu kwaye itshintshiwe kakhulu.

Ke ngoko, i-valve yesango elithambileyo yesango iya kuba yindlela yokuba ishishini lokuhambisa lamanzi liyakuvuyela ukwamkela. Okwangoku, ububanzi be-valve yesango elithambileyo esenziwe e-China yi-1500mm, kodwa ubukhulu beefestile ezininzi ziphakathi kwe-80-300mmm, kwaye kusekho iingxaki ezininzi kwinkqubo yokwenziwa kwezasekhaya. Icandelo eliphambili le-valve ethambileyo yesango yiplagi yerabha yerabha yerabha yerabha, kwaye iimfuno zobugcisa zerabha ziphezulu, kwaye ayizizo zonke iimveliso zangaphandle zinokufezekisa umzi-mveliso.

Ibhloko ye-pallper yetreyini yetywina elithambileyo lasekhayaI-Palve yesangoIfakwe kwaye ixhonywe ngaphezulu kweplate ye-velibe yerabha, efana ne-valve yesango, kwaye iqhekeza le-varve ilula ukuba lichaphazeleke kwibhloko esebenzayo ye-National. Kwindawo yesango letywina elithambileyo lenkampani yelinye ilizwe, ibhloko yentengiso ye-Copper iye yangena kwi-RAM egcwele irabha ukuze iyoyikeka iyonke, kodwa i-sundlity ye-fishverations kunye nebhunga le-valve liphezulu.

Nangona kunjalo, xa uvula kwaye uvale i-valve yesango elithambileyo, akufuneki ukuba ivalwe kakhulu, lo gama nje ifuthe lemilo yamanzi lifezekisiwe, kungenjalo akukho lula ukuvula intambo yerabha. Umenzi wevali, kuvavanyo lovavanyo lwe-valve, ukusetyenziswa kwenkungu yokuhambisa imigangatho yokuvala, njengabaqhubi beenkampani zamanzi kufuneka balandele le ndlela yokuvula nokuvalwa.

Yintoni umahluko phakathi kokusetyenziswa kweI-Butterfly ValveskwayeI-valves yesango?

Ngokwesebenzi kunye nokusetyenziswa kwe-valve yesango kunye nebhodlo yebhabhathane ye-valve yesango incinci, ukuba i-valve yesango ingekhoyo, kuba kulula i-valve, kwaye kulula ukonakalisa i-valve itywina.

I-Butterfly Valve, ekwabizwa ngokuba yiValve ye-flap, lukhona lwevalve elawula i-puidiel ephakathi, ijikeleze i-vatve ye-puidi, iveli ijikeleze i-vally yeentlobo, amanzi, I-Steam, imithombo yeendaba ezahlukeneyo ezongeziweyo, udaka, ioyile, ioyile yentsimbi ye-radio kunye nerediyo. Ibizana ikakhulu idlala indima yokusika kunye nokuqaqamba kumbhobho. I-Butterfly Volifly Valve kunye nenxalenye yokuvala ipleyiti yebhabhathane, ejikeleza i-axis yayo kwibhunga leValve, ukuze ifezekise injongo yokuvula nokuvalwa okanye ukulungisa.

Iplate yebhabhathane iqhutywa sisiqu se-valve, kwaye ukuba ijika i-70 ° 10, inokugqibezela ukuvula nokuvala. Ngokutshintsha i-angle yebhabhathane, inqanaba lokuhamba kwephakathi linokulawulwa.

Iimeko zomsebenzi kunye nePhakamileyo:Ibhotile yebhabhathaneIlungele ukuthutha imibhobho yemidiliya eyahlukeneyo kunye nengaqhelekanga yemithombo yeendaba kwiinkqubo zobunjineli, igesi ye-Coal, igesi ye-petroleum, igesi, igesi, njl., njl., njl njl.

I-Palve yeSango (i-valve yesango) kukuvula kunye nokuvalwa kwesango, indlela yokuhamba kwesango ingenziwa kuphela, i-valve yesango inokuvulwa ngokupheleleyo, i-5 ° 52 '. Ukuphucula ukuveliswa kwayo kwaye wenze ukuphambuka kwe-engile yokutywina kwinkqubo yokuqhubela phambili, olu hlobo lwe-RAM lubizwa ngokuba yi-elasticmm yenkunzi ye-elastic.

XaI-Palve yesangoIvaliwe, umphezulu wokutywina unokuxhomekeka kwingcinezelo ephakathi yokutywina, oko kukuthi, ixhomekeke kuphela kwixinzelelo oluphakathi ukucinezela umphezulu we-RAM ukuya kwelinye ukuqinisekisa ukutywina komgangatho wokutywina, onokutywina. Uninzi lwamasango lutywinwe ngenkani, oko kukuthi, xa ivalve ivaliwe, inkunzi yegusha kufuneka icinezelwe kwisitulo se-valve ngamandla angaphandle ukuqinisekisa ukuqina komgangatho wokutywina.

Imo yokuhamba: Iplate yesango ye-valve yesango ihamba ngomgca othe ngqo ne-valve, ebizwa ngokuba yivalve evulekileyo yesango. Ngokwesiqhelo kukho intambo yetreyini ekuphakameni kwentonga ephakamayo, nge-nati ephezulu yevalve kunye nesikhokelo i-roove kwi-roove kwi-value, oko kukuthi, i-torque esebenzayo itshintshwe ekusebenzeni. Xa ivalve ivuliwe, xa i-RAM iphakamisa ukuphakama ilingana ne-1: 1 Times ububanzi beValve, ukuhamba kwamanzi kungabekwa esweni ngokupheleleyo, kodwa esi sikhundla asinakubekwa esweni ngexesha lokusebenza. Ngokwenene ukusetyenziswa, iphawulwa yi-vertex yesikhondo, oko kukuthi, indawo engenakuvulwa, njengesikhundla sayo esivulekileyo. Ukwenzela ukuba unikezele nge-punomenon yokutshixa amaqondo obushushu, ihlala ivulwa kwisikhundla se-APEX, kwaye iphinde yabuyela kwi-1 / 2-1 ijika njengesikhundla sevalve evulekileyo. Ke ngoko, indawo evulekileyo ngokupheleleyo yevalve igqitywe sisikhundla segusha (okt stroke). Elinye isango le-stem stem ifikile esangweni, kwaye isandla sesandla sijikeleza i-valve iye yajikeleza, le valve ibizwa ngokuba yivalve yesango ejikelezayo.
