Endaweni eyinkimbinkimbi yokusebenza kwesiteshi samandla esiteshini, ama-boiler njengemishini eyisisekelo, ukuphepha kwako nokuqina kwahlobene ngokuqondile nokusebenza kahle kokusebenza kanye nokuphepha kwalo lonke uhlelo lokuphehla lwamandla. Njengedivayisi ebalulekile yokuvikela ngokweqile ku-boiler, design kanye nesiqinisekiso sokusebenza sokuvulwa nokuvala imingcindezi umehluko we-A41H-25I-valve yezokuphephazibaluleke kakhulu.

I-A41H-25 PhenduloIngabe i-valve yezokuphepha evulwa intwasahlobo evaliwe, elungele ikakhulukazi imishini noma amapayipi anama-medium anjenge-petroleum, umoya, amanzi, njll. I-valve yakhelwe futhi yenziwe ngokwejwayelekile ngokwejwayelekile kwe-Alinal Pressure standard, futhi ukuvala nokuvalwa kwe-valve kulawulwa ubudlelwano obulinganiselwe phakathi kwamandla aphezulu entwasahlobo kanye nengcindezi ephakathi, ukuze ukwazi ukubona ukuvikeleka ngokweqile kwemishini efana nama-boilers.

I-valve yamukela umgomo wokusebenza wokuvula nokuvala umehluko. Umehluko wokuvula nokuvala wengcindezi ubhekisa kumehluko phakathi kwengcindezi yokuvula kanye nengcindezi yokubuya ye-valve yezokuphepha, enquma ukuzwela nokuqina kwe-valve yezokuphepha. Umklamo wokuvulwa okufanele wokuvulwa nokuvala ingcindezi ungaqinisekisa ukuthi i-valve yezokuphepha iphendula ngokuhamba kwesikhathi lapho imishini icindezelwe, futhi isevala ngokumangala ngemuva kokuthi ingcindezi ibuyela kokujwayelekile, igweme ukukhishwa okuphakathi okungadingekile.

Ukushintshashintsha ukuguquguquka kohlelo lwe-boiler lwesiteshi samandla ashisayo kuvamile. Ukuze uqinisekise ukuthi i-valve yezokuphepha ayisebenzi kahle ngaphakathi kwebanga lokuguquguquka kwengcindezi, ingcindezi yokuvula kanye nobubanzi bokuthi izingcindezi zokuphepha ze-valve yezokuphepha kufanele zinqunywe ngokuya ngengcindezi yokusebenza ephezulu. Ngasikhathi sinye, khetha ukuqina kwentwasahlobo okufanele. Ukuqina kwentwasahlobo kunquma amandla okuvula nokuvala ama-valve ngaphansi kwengcindezi ehlukene, okuthinta ukuvala ukuphenduka nokuvala imihluko. Ngemuva kokusetha ingcindezi, ukuhlolwa kokulingisa kwenziwa ukuqinisekisa ukuthi ingabe umehluko wokuvula nowokuvala wengcindezelo ye-valve yokuphepha uhlangabezana nezidingo zokuklama. Ngesikhathi sokuhlola, ukuqina kwentwasahlobo namanye amapharamitha ahlobene aguqulwa ngokuqhubekayo kuze kube kutholakala ukusebenza okuhle.

I-A41H-25 yokuphepha yezokuphepha kumele ifakwe ngokuqondile nangokuhambisana ngqo nokuhlanganiswa kwe-boiler noma ipayipi ukunciphisa ithonya lokumelana namapayipi kanye nokuphuma kwe-Deaction Force ku-Valve Performance. Ngasikhathi sinye, ububanzi obungaphakathi bokuhlanganisa akufanele bube ngaphansi kobubanzi be-inlet ye-valve yezokuphepha ukuze kuqinisekiswe ukuhamba okubushelelezi kwendlela.

I-outlet ye-valve yezokuphepha kufanele ifakwe ngokuhlanganiswa okulungile kokunwetshwa ukuvikela ukwanda okushisayo kwepayipi lokukhipha kusuka ekubangeleni ukucindezelwa okushisayo kwe-valve yezokuphepha. Ububanzi obungaphakathi bepayipi le-pocing kufanele bube bukhulu kune-outlet ububanzi be-valve, futhi ubude kufanele bube mfushane ngangokunokwenzeka ukugwema ukuguqula ukumelana. Ngaphezu kwalokho, isisindo sepayipi lokukhululwa kanye nokujoka kokunwetshwa akufanele kusebenze nge-valve yezokuphepha, futhi kufanele kulungiswe esakhiweni ukuze kuqinisekiswe ukusebenza okuzinzile kwe-valve yephepha.

Ukuhlolwa njalo nokunakekelwa kwe-A41H-25 yokuphepha yezokuphepha kuyisihluthulelo sokuqinisekisa ukusebenza kwayo okuzinzile. Okuqukethwe kokuhlola kufaka phakathi isimo sentwasahlobo, ukugqokwa kobuso bendawo, noma ngabe ipayipi lokukhipha alikhonjwanga, njll. Uma kutholakala ukungahambi kahle, kufanele kuphathwe ngesikhathi ukugwema ukusebenza okujwayelekile kwe-valve evamile.
