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 kanye nesihlalo se-valve kuyahambisana, kanye 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
