Kufuneka ufake ivalve, kodwa ukukhetha uhlobo olungalunganga lunokuthetha iiyure zomsebenzi owongezelelweyo kamva. Ukulungiswa okulula kunokukunyanzela ukuba usike imibhobho kwaye uvale yonke inkqubo.

Ivalve yebhola edibanisa kabini inokususwa ngokupheleleyo kumbhobho ukuze ilungiswe, ngelixa ivalve yomanyano ingenako. Oku kwenza uyilo lomanyano oluphindiweyo luphakame kakhulu kulondolozo kunye nenkonzo yexesha elide.

Ukukwazi ukwenza inkonzo ngokulula kwivalvu ngumba omkhulu kwixabiso lilonke lobunini. Sisihloko esiphambili endixoxa ngaso namaqabane afana noBudi, umphathi wokuthenga e-Indonesia. Abathengi bakhe, ngakumbi abo bakwiindawo zemizi-mveliso, abanako ukufikelela ixesha elide lokwehla. Kufuneka bakwazi ukutshintsha izitywina zevalvu okanye umzimba wonke wevalvu ngemizuzu, hayi iiyure. Ukuqonda umahluko womatshini phakathi koyilo lomanyano olungatshatanga kunye noluphindwe kabini kuya kukunceda ukhethe ivalve ekongela ixesha, imali, kunye neentloko ezibuhlungu ezantsi kwendlela.

Yintoni umahluko phakathi kwevalve yebhola yomanyano enye kunye nevalve yebhola yomanyano ephindwe kabini?

Ubona iivalve ezimbini ezikhangeleka zifana kodwa zinamagama ahlukeneyo kunye namaxabiso. Oku kukwenza uzibuze ukuba ngaba ukhetho lomanyano olungabizi kakhulu "lulungile ngokwaneleyo" kwiprojekthi yakho.

Umanyano oluphindiweyo lufake izihlanganisi kuzo zombini iziphelo, ezivumela ukuba zisuswe ngokupheleleyo. Imanyano enye inesiqhagamshelanisi esinye, okuthetha ukuba icala elinye lizinziswe ngokusisigxina, ngokuqhelekileyo ngesamente enyibilikayo.

Yicinge njengokulungisa itayara lemoto. Ivalve yomanyano kabini ifana nevili elibanjwe ngamandongomane; ungasusa lonke ivili ukuze uyilungise. Ivalve yomanyano ifana nevili elidityaniswe kwi-asi kwelinye icala; awukwazi ukuyisusa ngenene inkonzo. Ungaqhawula kuphela isiphelo esinye kwaye usijiwulisele ngaphandle kwendlela. Ukuba umzimba wevalve ngokwawo uyasilela okanye kufuneka utshintshe amatywina, iumanyano oluphindiweyouyilo luphezulu kakhulu. Iikontraka zeBudi ziya kusebenzisa kuphela iivalvu eziphindwe kabini kwizicelo ezibalulekileyo kuba zinokutshintsha ngokupheleleyo ngaphantsi kwemizuzu emihlanu ngaphandle kokusika umbhobho omnye. Ixabiso elincinci elongezelelweyo langaphambili lizihlawulela ngokwalo okokuqala ngqa kufuneka ugcino.

Uthini umahluko phakathi kwevalve enye kunye nevalve ephindwe kabini?

Uva amagama afana ne "valve enye" ​​kunye "nevalve ephindwe kabini" kwaye uyabhideka. Unexhala lokuba usenokutolika ngendlela engeyiyo imigaqo yeprojekthi, nto leyo ekhokelela kwii-odolo ezingachanekanga.

“Ivalve enye” idla ngokuthetha ivalve elula, eneqhekeza elinye nengenamanyano. Igama elithi “ivalve ephindwe kabini” lisoloko lisisishunqulelo se“valve yebhola ephindiweyo,” eyiyunithi yevalvu enye edityaniswe kabini.

Isigama sinokuba nzima. Makhe sicacise. "I-valve enye" ​​kwindlela elula kakhulu ihlala "i-compact" okanyeivalve yebhola enye. Yiyunithi etywiniweyo encanyathiselwe ngokuthe ngqo kumbhobho. Ixabiso eliphantsi kwaye ilula, kodwa ukuba iyasilela, kufuneka uyinqumle. "Ivalve ephindwe kabini" okanye "ivelufa yomanyano kabini” ibhekisa kwimveliso yethu yeqhawe: iyunithi eneziqwenga ezithathu (iziphelo zomanyano ezimbini kunye nomzimba oyintloko) evumela ukususwa ngokulula. Kubalulekile ukuba ungabhidani oku kunye nokuseta "ibhloko ephindwe kabini", ebandakanya ukusebenzisa iivalvu ezimbini ezahlukeneyo, zodwa zokhuseleko oluphezulu. Kwi-99% yosetyenziso lwamanzi, enye "i-double union" yevalve yebhola ibonelela ngebhalansi yebhola egqibeleleyo kwaye inika ibhalansi yebhola egqibeleleyo kwaye inikezela ngenkonzo ekhuselekileyo yokuvala. naluphi na ufakelo olusemgangathweni.

IValve Serviceability Uthelekiso

Uthini umahluko phakathi kohlobo loku-1 kunye nohlobo lwesi-2 lwevalve yebhola?

Ujonge iplani yakudala okanye ishidi lenkcazo yomntu okhuphisana naye kwaye ubone "Udidi loku-1" okanye "uHlobo lwesi-2" ivelufa. Le jargon yakudala idala ukubhideka kwaye yenza kubenzima ukuthelekisa neemveliso zanamhlanje.

Esi sisigama esidala. “Uhlobo loku-1” ludla ngokubhekiswa kuyilo lwevalvu esisiseko, isiqwenga esinye. “Uhlobo 2″ lubhekiselele kuyilo olutsha oluphuculweyo olunokusebenza, oluthe lwavela kwiivalvu zebhola zomanyano lwanamhlanje.

Yicinge njenge "Uhlobo 1" imoto eyiModeli T kunye "noHlobo lwesi-2" ibe sisithuthi sanamhlanje. Iingqikelelo ziyafana, kodwa itekhnoloji kunye noyilo zahlukene kwihlabathi. Kumashumi eminyaka eyadlulayo, ishishini lasebenzisa la magama ukwahlula uyilo lwevalvu yebhola. Namhlanje, amagama aphelelwe lixesha, kodwa asenokuvela kwizicwangciso ezindala. Xa ndibona oku, ndichazela amaqabane afana noBudi ukuba iPntek yethuiivalvu zebhola yomanyanozindaleko zangoku zengqikelelo "Udidi lwesi-2". Ziyilwe ukusuka phantsi ukuya phezulu ukwenzela ukuba kube lula ukutshintshwa kwesihlalo kunye netywina kunye nokususwa emgceni. Kufuneka usoloko ukhankanya "ivalve yebhola yomanyano lokwenyani" ukuze uqinisekise ukuba ufumana imveliso yangoku, esebenza ngokupheleleyo, hayi uyilo oluphelelwe lixesha olusuka kumashumi eminyaka ubudala kwiphepha lengcaciso.

Yintoni umahluko phakathi kwe-DPE kunye neevalvu zebhola ze-SPE?

Ufunda i-data sheet yobugcisa ekhankanya izihlalo ze-DPE okanye ze-SPE. Ezi zifinyezo ziyabhida, kwaye uyoyika ukukhetha engalunganga kunokudala imeko yoxinzelelo oluyingozi kumbhobho wakho.

I-SPE (i-Single Piston Effect) kunye ne-DPE (i-Double Piston Effect) ibhekisela kwindlela izihlalo zevalve ezibamba ngayo uxinzelelo xa i-valve ivaliwe. I-SPE ngumgangatho we-PVC valves, njengoko ikhupha ngokuzenzekelayo uxinzelelo ngokukhuselekileyo.

Oku kufumana ubugcisa, kodwa ingcamango ibalulekile kukhuseleko. Kwivalve evaliweyo, uxinzelelo ngamanye amaxesha lunokubanjiswa kumbindi womzimba.

• SPE (Impembelelo yePiston enye):Lo ngumgangatho woshishino weenjongo jikelele zevalvu zebhola zePVC. AnIsihlalo se-SPEitywina ngokuchasene noxinzelelo olusuka kwicala elingasentla. Nangona kunjalo, ukuba uxinzelelo luyandangaphakathiumzimba wevalvu, unokutyhala ngokukhuselekileyo ngaphaya kwesihlalo esisezantsi kunye nokuphuma. Luyilo oluzikhululayo.
• I-DPE (Impembelelo yePiston ephindwe kabini): A Isihlalo se-DPEinokutywina ngokuchasene noxinzelelo oluvelazombinimacala. Oku kuthetha ukuba inokubamba uxinzelelo kumzimba womzimba, onokuba yingozi xa unyuka ngenxa yokwanda kwe-thermal. Olu luyilo lolwezicelo ezikhethekileyo kwaye lufuna inkqubo eyahlukileyo yokunceda umzimba.

Kuzo zonke izicelo ezisemgangathweni zamanzi, ezifana nabathengi beBudi, uyilo lwe-SPE lukhuselekile kwaye yintoni esizakhela kuyo.Iivalvu zePntek. Ikhusela ukwakheka koxinzelelo oluyingozi ngokuzenzekelayo.

Ukuqukumbela

Ivalve yebhola ephindwe kabini yomanyano iphezulu kuyo nayiphi na inkqubo efuna ukulungiswa, njengoko inokususwa ngokupheleleyo ngaphandle kokusika imibhobho. Ukuqonda uyilo lwevalvu kuqinisekisa ukuba ukhetha ngokuchanekileyo.
