Ukuqaliswa ngokutsha kofakelo kunye nokugcinwa kwePalve yoLawulo loNxweme

Ngokwenyani, i-valve yolawulo lombane isetyenziswe ngokubanzi kumzi-mveliso kunye nemigodi. I-valve yolawulo lombane idla ngokudityaniswa nge-Angulator ye-Angular Stroke Act kunye neVoterfly Valve ngoqhagamshelo loomatshini, emva kokufakwa kunye nokulungisa ingxaki. I-valve yolawulo lombane ye-valve ngokwemo yendlela yokuhlelwa: tshintsha uhlobo kunye nohlobo lommiselo. Oku kulandelayo yinkcazo ye-valve yolawulo lombane.

Kukho amanqaku amabini aphambili ekufanekelweni kwePalve yoMbane

1) Indawo yokufaka, ukuphakama kunye nendlela ye-inlet kunye nendawo yokuphuma kufuneka ifezekise iimfuno zoyilo. Indlela yokuhamba okuphakathi iya kuhambelana nendlela yokutolo ephawulwe kwibhunga leholide, kwaye uqhagamshelo luya kuqinisa kwaye luqinile.

2) Ngaphambi kokufakwa kweValve yoLawulo loNwenzi woLawulo, uhlolo lweLizwe kufuneka lwenziwe, kwaye i-valve yegama liya kuthobela uphawu lwe-valves "valves. kunye nokusika umsebenzi kumbhobho ophambili, amandla kunye novavanyo lokuqina luya kwenziwa ngaphambi kokufakwa, kwaye ivalve inokusetyenziswa kuphela emva kokuba ifanelekile. Ngexesha lovavanyo lwamandla, uxinzelelo lovavanyo luya kuba ngamaxesha ayi-1.5 koxinzelelo oluchanekileyo, ixesha aliyi kuba ngaphantsi kwe-5min, kwaye ukupakisha kuya kuba yinto yokuvuza.

Ngokwesakhiwo, ivalve yolawulo lombane inokwahlulwa ibe yiplate ye-sperset, iplate ethe nkqo, iplate etyekileyo kunye neqhosha le-lever. Ngokwefomu yokutywina, inokwahlulwa ibe ziindidi ezimbini: Uhlobo olutshiweyo kunye nohlobo oluqinileyo oluqinileyo. Uhlobo oluthambileyo lotywina luhlala lutywinwe nge-ring yerabha, ngelixa uhlobo lokutywina olunzima luhlala lutywinwa ngeringi yensimbi.

Ngokutsho kohlobo lonxibelelwano, ivalve yolawulo lombane iphumelele ukuba ihlulwe uqhagamshelo lweflethi kunye noqhawulo-mtshato; Ngokwendlela yokuhambisa, iyakwaziwa ibe yincwadi yencwadana, usulelo lwegiya, i-pneumatic, i-hydraulic kunye nombane.

Ukufakwa kunye nokugcinwa kwePalve yoLawulo loNcedo

1. Ngexesha lokufakwa, i-disc kufuneka iyeke kwindawo evaliweyo.

2. Indawo yokuvula kufuneka igqitywe ngokomjikelo webhola.

I-3. Kwivalve yebhola ene-valve edlula, ivalve ye-Bypass kufuneka ivulwe ngaphambi kokuvula.

I-4. I-valve yolawulo lombane ifakwe ngokwemiyalelo yokufakelwa komvelisi, kwaye ivalve enzima inikezwe isiseko esomeleleyo.
