I-NORTECHis enye yezona China ziphambiliIvalvu yeGlobe Umenzi kunye noMboneleli.

Zithini iingenelo kunye neengxaki zeivalvu yeglobhu?
Iindawo zokuvula nokuvala zevalvu yokuvala ziyi-plug-old broad petals, kwaye umphezulu wokuvala uthe tyaba okanye uyi-conical, kwaye uhamba ngokuthe tye kumgca osembindini wolwelo. Uhlobo lokushukuma kwentonga lunohlobo lwentonga yokuphakamisa (isiqu sevalvu siyaphakanyiswa kwaye sehliswe, ivili lesandla aliphakami), kwaye kukho uhlobo lwentonga yokuphakamisa ejikelezayo (ivili lesandla kunye nesiqu sevalvu ziyajikeleza kwaye zinyuka kunye, kwaye i-nut ibekwe emzimbeni wevalvu). Ivalvu yokumisa ifanelekile kuphela ukuba ivuleke ngokupheleleyo kwaye ivalwe ngokupheleleyo, ukulungiswa kunye nokugoba akuvumelekanga.
Ivalvu yokumisa yivalvu yokutywina enyanzelisiweyo, ngoko ke xa ivalvu ivaliwe, uxinzelelo kufuneka lufakwe kwi-flap ukuze kunyanzeliswe umphezulu wokutywina ukuba ungavuzi. Xa i-medium ingena kwi-valve ezintandathu ukusuka ngaphantsi kwediski yevalvu, ukumelana ekufuneka kunqotshwe ngamandla okusebenza ngamandla okungqubana kwesiqu sevalvu kunye nokupakisha kunye nokutyhala okuveliswa luxinzelelo lwe-medium. Amandla okuvala ivalvu makhulu kunamandla okuvula ivalvu, ngoko ke ivalvu Ububanzi bentonga kufuneka bube bukhulu, kungenjalo umbhobho wokujika isiqu sevalvu uya kusilela. Kwiminyaka yakutshanje, ukusukela oko kwavela iivalvu ezizitywinayo, indlela ephakathi yokuhamba kwevalvu yokuvala itshintshile ukusuka ngaphezulu kwevalvu ukuya kwi-valve cavity. Ngeli xesha, phantsi kwesenzo soxinzelelo oluphakathi, amandla okuvala ivalvu mancinci, ngelixa amandla okuvula ivalvu makhulu. Ububanzi bunokuncipha ngokufanelekileyo. Kwangaxeshanye, phantsi kwesenzo se-medium, olu hlobo lwevalvu nalo luqinile. Ivalvu yelizwe lam "iSanhua" yakha yathi indlela yokuhamba kwevalvu yokumisa kufuneka ibe ukusuka phezulu ukuya ezantsi.
Xa ivalvu yokuvala ivuliwe, xa ukuphakama kokuvula kwediski kungama-25%-30% yobubanzi obuqhelekileyo, ukuhamba kwamanzi kufikelele kwinqanaba eliphezulu, nto leyo ebonisa ukuba ivalvu ifikelele kwindawo evulekileyo ngokupheleleyo. Ke ngoko, indawo evulekileyo ngokupheleleyo yevalvu yokuvala kufuneka imiselwe ngokubetheka kwediski yevalvu.
Ivalvu yokumisa ingahlulwahlulwa ibe: ivalvu yokumisa, ivalvu yokumisa isiqu somsonto ophezulu, ivalvu yokumisa isiqu somsonto osezantsi, ivalvu yokumisa ethe tye, ivalvu yokumisa engile, ivalvu yokumisa eneendlela ezintathu, ivalvu yokumisa yangoku ngqo, ivalvu yokumisa iplunger, ivalvu yeglobhu enesimo senaliti.
Iingenelo: isakhiwo esilula, ukwenziwa kunye nokugcinwa okulula.
I-stroke yokusebenza incinci, kwaye ixesha lokuvula nelokuvala lifutshane.
Ukusebenza kakuhle kokutywina, ukungqubana okuncinci phakathi kwemiphezulu yokutywina, kunye nobomi obude.
Iingxaki:
Ukumelana kolwelo kukhulu, kwaye amandla afunekayo ekuvuleni nasekuvaleni makhulu.
Ayifanelekanga kwi-media eneziqwenga, i-viscosity ephezulu kwaye kulula ukuyicola.
Ukusebenza kakubi kohlengahlengiso
Amanyathelo okukhusela xa kufakelwa kwaye kugcinwa: Ivalvu yokumisa esebenza ngevili lesandla kunye nesiphatho ingafakwa nakweyiphi na indawo yombhobho.
Amavili esandla, izibambo kunye neendlela ezitshintshayo azivumelekanga ukuba zisetyenziswe ekuphakamiseni. Icala lokuhamba kwesixhobo kufuneka lihambelane necala lotolo oluboniswe emzimbeni wevalvu.
