Butterfly Valve Introduction

Selelekela:

Belofo ea serurubelee tsoa lelapeng la li-valve tse bitsoangli-valve tsa kotara. Ha e sebetsa, valve e bulehile ka ho feletseng kapa e koetsoe ha disc e potoloha ka kotara. “Serurubele” ke diski ea tšepe e kentsoeng holim’a molamu. Ha valve e koetsoe, disc e fetoloa e le hore e thibele ka ho feletseng tsela. Ha valve e bulehile ka ho feletseng, disc e potoloha ka kotara e le hore e lumelle tsela e batlang e sa thibeloa ea mokelikeli. Belofo e ka boela ea buloa butle-butle ho phalla.

Ho na le mefuta e fapaneng ea li-valve tsa serurubele, e 'ngoe le e' ngoe e etselitsoe likhatello tse fapaneng le ts'ebeliso e fapaneng. Belofo ea serurubele sa zero-offset, e sebelisang ho tenyetseha ha rabara, e na le maemo a tlase haholo a khatello. The high-performance double offset butterfly valve, e sebelisoang mekhoeng ea khatello e phahameng hanyenyane, e fokotsehile ho tloha moleng o bohareng oa setulo sa disc le setopo sa 'mele (offset one), le mohala o bohareng oa bore (offset two). Sena se theha ts'ebetso ea cam nakong ea ts'ebetso ea ho phahamisa setulo ho tsoa ho tiiso ho bakang khohlano e nyane ho feta e entsoeng ka moralo oa zero offset mme e fokotsa tloaelo ea eona ea ho roala. Belofo e loketseng hantle litsamaiso tsa khatello e phahameng ke valve ea serurubele sa triple offset. Ka valve ena, sebaka sa ho kopana le setulo sa disc se fokotsehile, se sebetsang ho felisa ho kopana ho thellang pakeng tsa disc le setulo. Tabeng ea li-valve tse tharo tsa "offset" setulo se entsoe ka tšepe e le hore se ka etsoa ka mechine e kang ho finyella bubble e tiileng ea ho koala ha e kopana le disc.

Li-valve tsa serurubele tse habeli-eccentric(li-valve tsa serurubele tse sebetsang hantle kapa li-valve tsa serurubele tse peli) - mefuta e fapaneng ea thepa e sebelisoa bakeng sa setulo le disc.

E phetha sena ka tiiso e tiileng e tiileng; ke hore, gasket, o-ring, precision machined, le sefahleho sa belofo e bataletseng ka mahlakoreng a holimo le a tlaase a belofo.

Belofo ea serurubele sa mofuta oa Lug

Li-valve tsa mofuta oa lugli kentse likhoele mahlakoreng ka bobeli a 'mele oa valve. Sena se ba lumella hore ba kenngoe tsamaisong e sebelisang lihlopha tse peli tsa liboutu le ho se na linate. Sephahla se kenngoa pakeng tsa li-flange tse peli ho sebelisa sete e fapaneng ea liboutu bakeng sa flange ka 'ngoe.

Belofo ea serurubele sa mofuta oa lug e sebelisoang litšebeletsong tsa batho ba shoeleng hangata e na le tekanyo e fokotsehileng ea khatello. Mohlala, belofo ea serurubele ea mofuta oa lug e pakeng tsa li-flange tse peli e na le sekhahla sa khatello ea 1,000 kPa (150 psi). Belofo e ts'oanang e kentsoeng ka flange e le 'ngoe, ts'ebeletso ea pheletso e shoeleng, e na le tekanyo ea 520 kPa (75 psi). Li-valve tse nang le li-lugged li hanyetsana haholo le lik'hemik'hale le lihlapolli 'me li khona ho mamella mocheso ho fihla ho 200 °C, e leng se etsang hore e be tharollo e fapaneng.
