Izinzuzo zama-valve epulasitiki?

Njengoba inani lamapayipi epulasitiki emanzini ashisayo nabandayo kanye nezicelo zobunjiniyela bamapayipi ezimbonini liqhubeka nokwanda, ukulawulwa kwekhwalithi yamavalvu epulasitiki ezinhlelweni zamapayipi epulasitiki kuya ngokuya kubaluleke kakhulu.

Ngenxa yezinzuzo zesisindo sokukhanya, ukumelana nokugqwala, ukungenwa kwe-adsorption yesikali, ukuxhumana okuhlanganisiwe namapayipi epulasitiki, nokuphila isikhathi eside kwesevisi yama-valve epulasitiki, ama-valve epulasitiki asetshenziswa ekuhlinzekeni kwamanzi (ikakhulukazi amanzi ashisayo nokushisa) kanye nolunye uketshezi lwezimboni. Kuhlelo lwamapayipi, izinzuzo zalo zokusetshenziswa azifani namanye ama-valve. Njengamanje, ekukhiqizeni nasekusetshenzisweni kwama-valve epulasitiki afuywayo, ayikho indlela enokwethenjelwa yokuwalawula, okubangela izinga elingalingani lamavalvu epulasitiki ukuze kutholakale amanzi kanye nolunye uketshezi olusetshenziswa ezimbonini, okubangela ukuvalwa kwe-lax nokuvuza kwezicelo zobunjiniyela. Ngokujulile, yenze isitatimende sokuthi ama-valve epulasitiki awakwazi ukusetshenziswa, okuthinta ukuthuthukiswa okuphelele kwezicelo zamapayipi epulasitiki. izindinganiso zikazwelonke zezwe lami zamavalvu epulasitiki asendleleni yokwakhiwa, futhi amazinga omkhiqizo wawo kanye nezindinganiso zendlela akhiwa ngokuvumelana nezindinganiso zamazwe ngamazwe.

Advantages of plastic valves

Emazweni ngamazwe, izinhlobo zama-valve epulasitiki ikakhulukazi zihlanganisa MF BALL VALVE, uvemvane valve, ama-valve okuhlola, ama-diaphragm valves, ama-valve esango kanye nama-valve okuvala. Amafomu esakhiwo amakhulu ama-valve anezindlela ezimbili, izindlela ezintathu kanye nanezindlela eziningi. Izinto zokusetshenziswa ngokuyinhloko ziyi-ABS, i-PVC-U, i-PVC-C, i-PB, i-PE, i-PP ne-PVDF njll.

Emazingeni omhlaba emikhiqizo yamavalvu epulasitiki, eyokuqala iwukudinga izinto ezingavuthiwe ezisetshenziswa ekukhiqizeni amavalvu. Umkhiqizi wezinto ezingavuthiwe kufanele abe nejika lokungaphumeleli kwe-creep elihlangabezana nezindinganiso zemikhiqizo yamapayipi epulasitiki [1]; ngesikhathi esifanayo, ukuhlolwa kokuvala uphawu kanye nomzimba we-valve wama-valve epulasitiki kuyadingeka. Ukuhlolwa, ukuhlolwa kokusebenza kwesikhathi eside kwe-valve ebalulekile, ukuhlolwa kwamandla okukhathala kanye netorque yokusebenza konke kubaluliwe, nempilo yesevisi yokuklama yevalvu yepulasitiki esetshenziselwa ukuthuthwa koketshezi ezimbonini iminyaka engu-25.
