Yini okufanele siyinake ngaphambi kokufaka i-valve butterfly?

Kuhlelo lwamapayipi e-PVC yezimboni, i-valve yohlobo lwesibambo ye-butterfly iwuhlobo oluvamile. Ngenxa yesakhiwo sale valve uvemvane incane uma kuqhathaniswa. Uma ufaka i-valve uvemvane phakathi nendawo ye-flange emikhawulweni yomibili yepayipi, ngebhawodi enamakhanda akabili phakathi kwe-flange yepayipi ukukhiya i-valve uvemvane, engakwazi ukulawula uketshezi lwamapayipi.

Ngenxa yokuthi ama-valve ovemvane afanele izindawo ezinesikhala esincane noma ibanga elifushane phakathi kwamapayipi, lapho i-valve uvemvane isendaweni evulekile, i-valve flap iwukuphela kokumelana nokugeleza kwe-medium emzimbeni we-valve, ngakho-ke ingcindezi ekhiqizwa i-valve. incane uma kuqhathaniswa, futhi kukhona ukulawula okungcono kokugeleza kwe-medium. Lokhu kwenza i-valve yohlobo lwesibambo idume kakhulu emakethe yamapayipi embonini, kodwa kunamaphuzu ayisikhombisa okufanele siwanaka ngaphambi kokufaka isibambo sohlobo lwe-butterfly valve.

1, Kodwa kukhona amaphuzu ayisikhombisa okufanele sinake ngaphambi kokufaka isibambo se-butterfly valve.

I-2, Ngaphambi kokufaka i-valve ye-butterfly, ingaphandle lepayipi kufanele lifafazwe ngomoya futhi ingaphakathi lepayipi kufanele ligezwe ngamanzi.

I-3, Kufanele sihlole ngokucophelela ukuthi ukusebenza kwe-valve butterfly nokusetshenziswa kwesimo kuyahambisana, njengokushisa, ukucindezela nokunye.

4,Kufanele sihlole indawo yokuvala yevalve uvemvane kanye neshaneli yevalvu ngaphambi kokufakwa ukuze sibone ukuthi ayikho yini imfucumfucu futhi siyihlanze ngesikhathi.

Ama-valve e-butterfly kufanele afakwe ngaphandle kwebhokisi ngesikhathi esifanele, futhi noma yiziphi izikulufa zokulungisa eziqinile noma amantongomane ku-valve akufanele zithukululwe ngokuthanda kwakho.

5, Sebenzisa ama-valve ovemvane akhethekile kuma-valve ohlobo lwesibambo.

6, I-valve uvemvane kagesi ngoba ingafakwa kunoma iyiphi i-engeli yepayipi, ngakho-ke ukuze ugcine ukunethezeka kwakamuva, ngokuvamile akunconywa ukufaka i-valve butterfly kagesi ibheke phansi.

I-7, Lapho ufaka i-valve flange ye-butterfly, kufanele siqinisekise ukuthi i-flange surface kanye nerabha yokuvala igxilile, qinisa izikulufu zokulungisa, futhi indawo yokuvala kufanele ifaneleke futhi iphelele: uma kukhona amandla okuqina okungalingani kwezikulufu, kuzoholela kupuleti uvemvane olunezingqimba zeraba noma ngaphezulu kwepuleti levemvane ukuze kubangele ukuvuza esiqwini sevalvu.
