Ivalve yebhabhathane enedayamitha enkulu

Ukuthelekisa ukusebenza kwevalve yebhabhathane edayamitha enkulu kunye nevalve yesango:

Ivalve yesango inomthamo omkhulu kwaye ithatha indawo enkulu. Inokunyamezela uxinzelelo olukhulu.

Ivalve yebhabhathane inomthamo omncinci kwaye ithatha indawo encinci. Inokumelana noxinzelelo oluncinci.

Ukukhetha okuthe ngqo, kodwa qwalasela ubushushu bendawo ephakathi, ukutywinwa kwevalve kunye nokupakishwa.

Inkcazo imisela ukuba ivalve yebhabhathane enedayamitha engaphezulu kwe-50cm kufuneka isetyenziswe.

Ivalve yebhabhathane enedayamitha enkulu yimveliso entsha engundoqo yesizwe. Ivalve yebhabhathane yokusebenza ephezulu ithatha i-eccentric ephindwe kabini kunye nesakhiwo esikhethekileyo se-cone elliptical seal. Isombulula ingxaki yokuba umphezulu wokutywina wevalve yebhabhathane yemveli isekwi-sliding friction ngexesha lokuvula nokuvala ukusuka kwi-0 ° ukuya kwi-10 ° kwaye ifezekisa isiphumo sokwahlula umphezulu wokutywina ngexesha lokuvulwa kunye nokutywinwa ngalo mzuzu wokuvalwa, ukuze kwandiswe ubomi benkonzo kwaye bafezekise owona msebenzi wokutywina.

Ukusetyenziswa kwevalve yebhabhathane edayamitha enkulu:

Isetyenziselwa umbhobho werhasi kwishishini leasidi yesulfuric:i-inlet kunye ne-outlet ye-blower phambi kwesithando somlilo, i-inlet kunye ne-outlet ye-fan ye-relay, i-valve ye-demister series valve kunye ne-valve yokudibanisa, i-inlet kunye ne-outlet ye-S02 i-blower ephambili, umgaqo wokuguqula, i-inlet kunye ne-outlet ye-preheater, njl. kunye nomthamo wegesi osikiweyo. Isetyenziselwa ukutshisa isulfure, ukuguqulwa kunye necandelo lokufunxa elomileyo le-sulfure evuthayo inkqubo ye-sulfuric acid. Luphawu olukhethwayo lweevalvu zesityalo se-sulphuric esivuthayo sesulfure. Ithathwa luninzi lwabasebenzisi njengeevalve zebhabhathane kunye nokusebenza kakuhle kokutywinwa, ukusebenza okulula, ukubola kwemveliso, ukumelana nobushushu obuphezulu, ukusebenza ngokulula kunye nokuguquguqukayo, ukusetyenziswa okukhuselekileyo nokuthembekileyo, kwaye sele isetyenziswa ngokubanzi. Ikwasetyenziswa ngokubanzi kwimibhobho ye-SO2, umphunga, umoya, igesi, i-ammonia, i-CO2, i-oyile, amanzi, i-brine, i-alkali, amanzi olwandle, i-nitric acid, i-hydrochloric acid, i-sulfuric acid, i-phosphoric acid kunye neminye imithombo yeendaba kwimichiza, i-petrochemical, i-smelting, i-pharmaceutical, ukutya kunye namanye amashishini athintela njengezixhobo zokulawula.

Iimpawu zevalve yebhabhathane enkulu:

① Uyilo olulodwa lwendlela-ntathu eccentricity lwenza ukutywinwa komhlaba kuqhube ngaphandle kokukhuhlane kwaye kwandise ubomi benkonzo yesivalo.

② Isitywina esilastiki senziwa ngetorque.

③ Umphezulu wokutywina we-cuneiform unomsebenzi wembuyekezo yokuvuza.

④ Umthamo omncinci, ubunzima obulula, ukusebenza okulula kunye nokufakwa lula.

⑤ Ngokweemfuno zabasebenzisi, izixhobo ze-pneumatic kunye nezombane zinokumiselwa ukuhlangabezana neemfuno zolawulo olukude kunye nolawulo lwenkqubo.

⑥ Izinto zamalungu atshintshiweyo zingasetyenziswa kuzo zonke iindidi zemidiya, kwaye zingasetyenziselwa ulwakhiwo lokuchasa umhlwa (F46, gxpp, Po, njl. njl.).

⑦ Ulwahlulo oluqhubekayo lwesakhiwo: i-clamp, i-flange, i-butt welding.
