Isimiso sokuSebenza seValve Ezilawulayo Ezisebenza Ngokwakho

Abantu abaningi bayazibuza ukuthi iyini i-valve ezilawulayo. Eqinisweni, i-valve ezilawulayo incike ekucindezelweni kwe-medium egeleza nge-valve ngokwayo, futhi izinga lokushisa lisebenza njengomthombo wamandla.

I-valve isebenza ngokuzenzakalelayo ngaphandle kokunikezwa kwamandla kwangaphandle kanye nensimbi yesibili. Ngakho-ke iyiphi indlela yokusebenza ye-valve yokulawula ezisebenza yona?

1. Indlela yokusebenza

Amavalvu ezilawulayo azisebenza wona ancike kumageji omfutho wedijithali ageleza phakathi nendawo ngokwayo kunethiwekhi. I-Celsius isetshenziswa njenge-valve ehambayo endaweni yamandla ukuze isebenze ngokuzenzakalelayo. Kudingeka amandla angaphandle kanye namabili.

I-instrumentation yesibili. Le valve ezilawulayo isebenzisa umthombo wesignali ehlanekezelwe (igeji ye-digital pressure, ingcindezi ehlukile. Celsius) ekugcineni kwevalvu ukuze idlulisele enhlanganweni yokusebenza ngeshubhu yomthombo wesignali.

I-disc yokushayela ishintsha ukuvuleka kwe-valve ukulungisa igeji ye-digital pressure, izinga lokugeleza kanye ne-Celsius. I-valve yokulawula ingahlukaniswa ngemisebenzi eqondile nengaqondile.

Izinhlobo ezimbili.

I-valve yokulawula esebenza ngokuzenzakalelayo, eyaziwa nangokuthi uhlobo olulayishwe entwasahlobo, inezingxenye ezinwebekayo ezifana nentwasahlobo, izifutho, izifutho, amaphakethe okushisa, njll. esakhiweni sayo.

Umgomo webhalansi phakathi kwamandla aqinile kanye nomthombo wesignali wempendulo ukuthi uma kusetshenziswa ivalvu elawulayo yohlobo lwe-digital pressure eyeball_type, umthombo wesignali yempendulo iyigeji yokucindezela kwedijithali ekuphumeni kwevalvu.

Amapayipi omthombo angeniswa enhlanganweni yokusebenza. Uma kusetshenziswa i-valve ezilawulayo ngokugeleza, kunepuleti le-orifice (noma enye idivayisi elwa nokujama) endaweni yokuphuma kwevalvu ukuze kukhishwe ukucindezela kuzo zombili iziphetho ze-orifice plate.

Umthombo wesignali ohlukile wethulwa enhlanganweni yokusebenza. Uma inethiwekhi ezilawulayo inedigri ye-Celsius, ukuphuma kwevalvu kuzoba nenzwa ye-Celsius (noma igumbi lokushisa) ngokwethulwa kwenzwa ye-Celsius.

Inhlangano yokusebenza yokwandisa okushisayo kanye ne-contraction drive.

2.Amanothi okufaka

(1) indawo yokucindezela kufanele ibekwe endaweni efanele yevalve elawula ukucindezela. Ukucindezela kufanele kube ngaphezu kwezikhathi ezingu-2 ububanzi bepayipi ngaphambi kwe-valve, futhi ingcindezi emva kwe-valve kufanele ibe ngaphezu kwezikhathi ezingu-6 ububanzi bepayipi.

(2) Ngokwezibalo, ububanzi be-valve yebhola leso bungaba buncane kunepayipi, kuyilapho ububanzi be-valve yembulunga, i-valve yebhola esikiwe, i-bypass valve kanye nesihlungi angeke kube kuncane kunalokho. wepayipi.

Isifinyezo esingenhla solwazi mayelana nendlela yokusebenza kwevalvu yokulawula ukubona, ngikholwa ukuthi ufunde ulwazi oluningi ngemuva kokuyibuka.

Ulwazi luwusizo kakhulu kubantu abaningi, ngakho ake silubheke.
