Izinhlobo nemisebenzi yama-valve amakhemikhali
Uhlobo oluvulekile noluvaliwe: nqamula noma uxhumane nokugeleza koketshezi epayipini;uhlobo lokulawula: lungisa ukugeleza kanye nesivinini sepayipi;
Uhlobo lwe-throttle: yenza uketshezi lukhiqize ukwehla kwengcindezi enkulu ngemva kokudlula ku-valve;
Ezinye izinhlobo: a.Ukuvula nokuvala okuzenzakalelayo b.Ukugcina ingcindezi ethile c.Ukuvimbela umusi kanye nokukhipha amanzi.
Izimiso zokukhetha i-valve yamakhemikhali
Okokuqala, udinga ukuqonda ukusebenza kwe-valve.Okwesibili, udinga ukuqonda izinyathelo kanye nesisekelo sokukhetha i-valve.Okokugcina, kufanele ulandele izimiso zokukhetha ama-valve ezimbonini ze-petroleum namakhemikhali.
Amavalvu amakhemikhali ngokuvamile asebenzisa imidiya okulula ukugqwala.Kusukela embonini elula ye-chlor-alkali kuya embonini enkulu ye-petrochemical, kunezinkinga ezifana nokushisa okuphezulu, ukucindezela okuphezulu, okubolayo, ukugqokwa okulula, kanye nokwehluka okukhulu kwezinga lokushisa nokucindezela.I-valve esetshenziswa kulolu hlobo lwengozi ephakeme kufanele isetshenziswe ngokuqinile ngokuhambisana nezindinganiso zamakhemikhali ekukhetheni nasekusetshenzisweni kwenqubo.
Embonini yamakhemikhali, ama-valve anemigudu eqondile yokugeleza ngokuvamile akhethiwe, anokumelana nokugeleza okuphansi.Ngokuvamile asetshenziswa njengama-valve aphakathi nendawo avaliwe.Amavalvu okulula ukulungisa ukugeleza asetshenziselwa ukulawula ukugeleza.Ama-valve okuxhuma nama-valve ebhola afaneleka kakhulu ukuhlehla nokuhlukanisa., I-valve enomthelela wokusula ekusheleleni kwelungu elivala eduze kwendawo yokuvala ifaneleka kakhulu endaweni enezinhlayiya ezimisiwe.Ama-valve amakhemikhali avamile ahlanganisa ama-valve ebhola, ama-valve esango, ama-globe valves, ama-valve okuphepha, ama-plug valve, ama-sheke valve nokunye.Imithombo yemithombo ye-valve yamakhemikhali iqukethe izinto zamakhemikhali, futhi kunemithombo eminingi ye-acid-base corrosive media.I-chemical valve material ye-Taichen factory ikakhulukazi i-304L ne-316. Imidiya evamile ikhetha i-304 njengento ehamba phambili.Uketshezi olubolayo oluhlanganiswe namakhemikhali amaningi enziwe ngensimbi yengxubevange noma ivalve ene-Fluorine-lined.
Izinyathelo zokuqapha ngaphambi kokusebenzisa ama-valve amakhemikhali
① Ukuthi kukhona ukukhubazeka okufana namabhamuza nokuqhekeka endaweni engaphakathi nengaphandle yevalvu;
②Ukuthi isihlalo se-valve kanye nomzimba we-valve kuhlanganiswe ngokuqinile, noma ngabe i-valve core nesihlalo se-valve kuyahambisana, nokuthi indawo yokuvala ayisebenzi yini;
③Ukuthi ukuxhunyaniswa phakathi kwesiqu se-valve ne-valve core kuyavumelana nezimo futhi kuthembekile, noma ngabe isiqu se-valve sigobile, nokuthi intambo yonakele yini
