Ivalve elawula umbane luhlobo lwesivalo esisebenzisa amandla ombane ukulawula ukuhamba okuphakathi ngokuguqula umsantsa phakathi kondoqo wevalve kunye nesitulo sevalvu. Isetyenziswa kakhulu kwimveliso yemizi-mveliso kwi-petroleum, ishishini lemichiza, isinyithi, ulwakhiwo, amandla ombane kunye nezinye iindawo. Eli nqaku liza kwazisa umgaqo wokusebenza kunye neempawu zokusebenza zevalve yokulawula umbane ukusuka kwindawo yokujonga ingcali.
Okokuqala, umgaqo wokusebenza
1. Ukwakhiwa kwesakhiwo
Ivalve yokulawula umbane ubukhulu becala yenziwe ngumzimba, i-spool, isihlalo, i-actuator yombane kunye nenzwa. Phakathi kwabo, izinga lokuhamba kwe-medium lihlengahlengiswa nge-gap ethile phakathi kwe-valve core kunye nesihlalo se-valve.
2. Indlela esebenza ngayo
Umgaqo osebenzayo we-valve yokulawula umbane unokushwankathelwa nje ngolu hlobo lulandelayo: inzwa iguqula utshintsho lokuhamba kwamanzi, uxinzelelo, ubushushu kunye nezinye iiparitha kwiimpawu zombane, ezithunyelwa kwinkqubo yokulawula. Ngokokuphambuka phakathi kwexabiso elimiselweyo kunye nexabiso langempela, inkqubo yokulawula itshintsha i-gap phakathi kwe-valve core kunye nesihlalo ngokuqhuba i-actuator yombane, ukwenzela ukuba kulungiswe izinga lokuhamba kwe-medium, ukwenzela ukuba ixabiso langempela lihambelana. ngexabiso elibekiweyo.
Okwesibini, iimpawu zokusebenza
1. Ukuchaneka okuphezulu kohlengahlengiso
I-valve yokulawula yombane ithatha inkqubo yokulawula i-loop evaliweyo, enokuthi ilungiswe ngokuchanekileyo ngokuphambuka phakathi kwexabiso elimiselweyo kunye nexabiso langempela, kwaye inokulungiswa okuphezulu kokuchaneka.
2. Isantya sokuphendula ngokukhawuleza
I-valve yokulawula yombane iqhutywe ngumbane, kwaye i-actuator inomsebenzi omkhulu wokuqhuba, onokuqonda ukuvulwa ngokukhawuleza kunye nokuvala kunye nokulungelelaniswa okuchanekileyo, kunye nokuhlangabezana neemfuno zokuphendula ngokukhawuleza kolawulo lokuhamba kwimveliso yezoshishino.
3. Ukuthembeka okuphezulu
Iinxalenye zevalve yokulawula yombane ziyimveliso eqhelekileyo, ekulula ukuyilungisa nokutshintsha. Ngelo xesha, i-actuator yombane inomsebenzi wokukhusela wokugqithisa, ukufudumala, ukungaphumeleli kwamandla, njl., Okuphucula ukuthembeka kwe-valve.
4. Uyakwazi ukuziqhelanisa neemeko
Iivalve zokulawula umbane zingasetyenziswa ngokubanzi kulawulo lokuhamba kweendaba ezahlukeneyo, njengegesi, ulwelo, umphunga, njl. Ngelo xesha, izinto ezifanelekileyo kunye neefom zokutywinwa zingakhethwa ngokweemeko ezahlukeneyo zokusebenza ukuphucula ukulungelelaniswa kwevalve. .
5. Ukonga amandla kunye nokukhuselwa kwendalo
Xa kuthelekiswa ne-valve yolawulo lwemveli, i-valve yokulawula umbane inezinga eliphezulu lokuzenzekelayo, inokufikelela kulawulo olukude kunye nolawulo oluphakathi, kunye nokunciphisa iindleko zabasebenzi. Ngelo xesha, i-valve yokulawula umbane inokulawula ngokuchanekileyo ukuhamba, ukunciphisa inkunkuma yamandla, kwaye ilungele ukonga amandla kunye nokukhuselwa kwendalo.
Iii. Isishwankathelo
Ivalve yokulawula umbane ineempawu zokusebenza zokuchaneka okuphezulu kohlengahlengiso, isantya sokuphendula ngokukhawuleza, ukuthembeka okuphezulu, ukuguquguquka okuqinileyo, ukonga amandla kunye nokukhuselwa kwendalo, kwaye ibe sisixhobo sokulawula ukuhamba okuyimfuneko kwimveliso yeshishini. Ukuqonda umgaqo wokusebenza kunye neempawu zokusebenza zevalve yokulawula umbane kunceda ukukhetha ngcono nokusebenzisa i-valve yokulawula umbane ukuqinisekisa ukusebenza okukhuselekileyo, okuthembekileyo kunye nokusebenza kakuhle kwenkqubo yokuhambisa umbane.
