Sivame ukuzwa ukuthiukufakwa kwepayipi le-ferrule eliphindwe kabilifuthiamavalvuAkulula ukuzisebenzisa, azithembekile, futhi ziyavuza ngemva kokuhlolwa kokufakwa. Kungakhathaliseki ukuthi i-nut iqine kangakanani, ayisebenzi. Futhi sivame ukuzwa ukuthiukufakwa kwepayipi le-ferrule eliphindwe kabilifuthiamavalvuekuvuvukeni kwepayipi ngemuva nje kokusetshenziswa. Yini ebangela lokhu kuvuza?
Isizathu ngokuvamile ukuthi awuqiniseki ngamaphuzu amathathu abalulekile. Ukwazi lezi zinyathelo ezintathu kungaxazulula kalula uxhumano lwe-ferrule oluphindwe kabili.
Okokuqala, khethaukufakwa kwepayipi le-ferrule eliphindwe kabilikanye neminye imikhiqizo evela kumikhiqizo emikhulu. Umkhiqizo we-double ferrule osezingeni eliphezulu uyisinyathelo esibalulekile empumelelweni. Isibonelo: i-Swgelok, i-Parker, i-Hikelok, njll. Ngoba ngemva kokuba imikhiqizo ye-double ferrule ixhunyiwe, i-double ferrule kanye ne-tubing kuyahlanganiswa, futhi i-double ferrule iqedela ukubopha nokuvala, ngokuguquguquka okuhlala njalo, lolu hlobo lomkhiqizo alukwazi ukuhlolwa ngokugcwele njengama-valve lapho luphuma efektri. Lungathembela kuphela kubuchwepheshe obuqinile kanye nokulawulwa kwenqubo okusekelwe olwazini ukuqinisekisa ukuthi ikhwalithi yemikhiqizo eyizigidi iyahambisana. Eminye imikhiqizo ekhiqizwa amafektri amancane ayiqinisekisiwe.
Okwesibili, khetha amapayipi afanelekayo. Amapayipi kumele ahlangabezane nezinga le-ASTM A269, okuyisidingo esincane okufanele abakhiqizi abavamile bakwazi ukusifinyelela. Ngaphezu kokuhlangabezana namazinga, udinga futhi ukunaka kakhulu ikhwalithi engaphezulu yepayipi. Akufanele kube nemigodi noma imihuzuko emide. Ikhwalithi enhle yobuso ibalulekile ekuxhumekeni kwe-ferrule ephindwe kabili, ngoba ukuxhumana kwe-ferrule ephindwe kabili kuyisiciko esiqinile sensimbi, futhi ubuso bepayipi obuhle bungaqinisekisa ukuvalwa. Ngesikhathi esifanayo, udinga futhi ukukhetha ipayipi enobunzima obufanele. Ubunzima bepayipi ngokuvamile budingeka ukuthi bube yi-HRB ≤ 85, kanti amapayipi ane-annealing engalingani anobunzima obuhlukile. Amapayipi engxenyeni eqinile afana nengxenye yokuxhumana kwe-ferrule, okuzobangela ukuthi ipayipi lingaboshwa kahle yi-ferrule futhi kunengozi yokuhlukaniswa kwamapayipi. Udinga futhi ukunaka ukuzungeza kwepayipi, njengoba amapayipi e-elliptical awakwazi ukuvala kahle. Uma ungakwazi ukulawula lezi zici, kunconywa ukuthi ukhethe umenzi ongahlinzekaukufakwa kwepayipi le-ferrule eliphindwe kabili, amavalvukanye nokuthenga amapayipi ndawonye.
Okwesithathu, ukufakwa okufanele kuyisinyathelo sokugcina ezinyathelweni ezibalulekile zokuxhuma i-ferrule ephindwe kabili. Sebenzisa umshini wokusika ishubhu obukhali ukusika ishubhu, sebenzisa ithuluzi lokususa i-burrs emachwebeni angaphakathi nangaphandle eshubhu, faka ishubhu phansi kwe-ukufakwa kwepayipi le-ferrule eliphindwe kabili or ivalvu, maka indawo yentonga uma iqhathaniswa nepayipi ngepeni lokuphawula, bese uqedela ukufakwa ngokujika okungu-1-1/4. Khumbula ukungafaki ngokusekelwe ekuqondeni noma ekuqondeni. Ukuze uthole imiyalelo ethile yokufaka, sicela ubheke amavidiyo omhlahlandlela wokufaka we-Hikelok.
Ngezinyathelo ezintathu ezilula, uhlelo lwakho ngeke lusakhathazwa ukuvuza.
UHikelok, umkhiqizi ochwepheshe wama-valve ezinsimbi kanye nokufakwa kwazo.
Ukuze uthole imininingwane eyengeziwe yoku-oda, sicela ubheke okukhethiweamakhathalogikuvuliweIwebhusayithi esemthethweni kaHikelokUma unemibuzo yokukhetha, sicela uxhumane nabasebenzi bezokuthengisa abangochwepheshe be-Hikelok abasebenza amahora angama-24 online.
