Ukusetyenziswa kunye neempawu zesakhiwo se-elastic metal hard sealing butterfly valve

I-elasticivalve yebhabhathane yokutywina ngentsimbiyimveliso entsha engundoqo yesizwe.Ivalve yebhabhathane ene-elastic yentsimbi yokutywina ithatha i-double eccentric kunye nesakhiwo esikhethekileyo sokutywinwa se-cone se-elliptical sealing.Isombulula into engeloncedo yokuba umphezulu wokutywina wevalve yebhabhathane yemveli isekwi-sliding contact friction ngexesha lokuvula nokuvala i-0 ° ~ 10 °, kwaye iqonda isiphumo sokuba umphezulu wokutywina wepleyiti yebhabhathane yahluliwe ngalo mzuzu. wokuvula, kunye nokutywinwa kuvaliwe xa uqhagamshelwano luvaliwe, ukwenzela ukwandisa ubomi benkonzo kunye nokufezekisa ukusebenza kokutywinwa.injongo entle.

sebenzisa:

Isetyenziselwa imibhobho yerhasi kwishishini le-asidi yesulfuric: indawo yokungena kunye nokuphuma kwesivuthela phambi kweziko, indawo yokungena kunye nokuphuma kwefeni yokudlulisa umbane, uthotho kunye neevalvu zoqhagamshelo lwe-demister yombane, indawo yokungena kunye nokuphuma kombane. I-S02 i-blower ephambili, ukulungiswa kwe-converter, i-inlet kunye ne-outlet ye-preheater, njl kunye nokusetyenziswa kwegesi ecinyiweyo.
Isetyenziselwa ukutshisa isulfure, ukuguqulwa kunye nokufunxa okomileyo kwinkqubo ye-asidi ye-sulfuric.Luphawu olukhethwayo lweevalvu zezityalo ze-sulfuric acid.Ithathwa luninzi lwabasebenzisi njengoku: ukusebenza kakuhle kokutywina, ukusebenza ukukhanya, ukubola kwesibini, ukumelana nobushushu obuphezulu, ukusebenza kakuhle, iivalve zebhabhathane eziguquguqukayo, ezikhuselekileyo nezithembekileyo ziye zasetyenziswa ngokubanzi.
Ikwasetyenziswa ngokubanzi kwi: SO2, umphunga, umoya, igesi, ammonia, igesi CO2, ioli, amanzi, i-brine, i-lye, amanzi olwandle, i-nitric acid, i-hydrochloric acid, i-sulfuric acid, i-asidi ye-phosphoric kwimichiza, i-petrochemical, i-smelting, i-pharmaceutical, ukutya kunye namanye amashishini Isetyenziswa njengesixhobo esilawulayo nesivalayo kwimibhobho efana nephakathi.

Iimpawu zesakhiwo:
①Uyilo olulodwa lwendlela-ntathu eccentricity lwenza ugqithiso olungena-friction phakathi komphezulu wokutywina kunye nokwandisa ubomi benkonzo yesivalo.
②Itywina le-elastic iveliswa ngetorque.
③Uyilo oluchubekileyo olumile okwe weji lwenza ukuba ivalve ibe nomsebenzi wokutywina ozenzekelayo wokuvala nokuqinisa, kwaye umphezulu wokutywina unembuyekezo kunye nokuvuza kweqanda.
④Ubungakanani obuncinci, ubunzima obulula, ukusebenza okulula kunye nokufakwa lula.
⑤Izixhobo zomoya kunye nombane zinokumiselwa ngokweemfuno zomsebenzisi ukuhlangabezana neemfuno zolawulo olukude kunye nolawulo lwenkqubo.
⑥Impahla yamalungu atshintshiweyo ingasetyenziswa kumajelo ohlukeneyo, kwaye inokufakwa kwi-anti-corrosion (i-lining ene-F46, GXPP, PO, njl. njl.).
⑦ Ulwahlulo oluqhubekayo lwesakhiwo: i-wafer, i-flange, i-butt welding.
