1. Shisela i-flange epayipini bese upholisa ukuya kumazinga okushisa asendaweni ngaphambi kokukhweza i-valve ku-flange.Uma kungenjalo, izinga lokushisa eliphezulu elikhiqizwa yi-welding lizothinta ukusebenza kwesihlalo esithambile.
2. Imiphetho yama-flange ashiselwe kufanele ifakwe ama-lathe endaweni ebushelelezi ukuze kugwenywe ukulimala kwesihlalo esithambile ngesikhathi sokufakwa kwe-valve. I-flange surface kufanele ingabi namonakalo ngokuphelele kanye nokuguqulwa, isuse konke ukungcola, uthuli nezinto zangaphandle, futhi igweme ukuvuza kwe-valve noketshezi. isikhombimsebenzisi se-flange.
3. Hlanza i-flange kanye nomgodi ongaphakathi wepayipi ukuze ususe ngokuphelele isifafazi, isikali kanye nezinye imizimba yangaphandle eshiywe ngokushisela.
4. Uma ufaka amapayipi phakathi kwama-valve, ukuqondanisa okunembile kwenkaba yemigqa yamanzi engenhla nangaphansi kubalulekile ekusebenzeni okungenazinkinga.Iphuzu lesikhungo elingaqondakali eliboniswe kuMfanekiso 1 kufanele ligwenywe.
5. Uma ufaka i-valve, lungisa ama-bolts okumisa phansi kwepayipi ekuphakameni okufanayo ukuze udlale indima esekelayo, futhi ulungise ibanga phakathi kwama-flange kuze kube izinhlangothi ezimbili zomzimba we-valve zihlukene ngo-6-10 mm. Khumbula ukuthi i-valve ingavulwa kuphela ukusuka endaweni evaliwe ukuya endaweni engu-10°.
6. Faka amabhawodi amabili kubha yomhlahlandlela engezansi yevalvu bese ufaka ngokucophelela ukuze indawo ye-flange ingalimazi isihlalo esithambile.6.(bheka umfanekiso 2)
7. Bese ufaka amanye amabhawodi amabili entongeni yomhlahlandlela ngaphezu kwevalvu, uqinisekise indawo emaphakathi enembile phakathi kwepayipi nevalvu.
8. Vula i-valve kathathu ukuze uhlole ukuthi ukuxhumana phakathi kwepuleti le-valve ne-flange akubushelelezi.
9. Susa amabhawodi okumisa bese ubeka wonke amabhawodi azungeze umzimba ngokushintshana kwe-diagonal tighten (bheka ama-Fig. 3 no-4) kuze kube yilapho i-flange ithinta umzimba.
10. Nikeza usekelo lwevalvu lapho ufaka i-actuator ukugwema ukusonteka kwentamo yevalvu futhi unciphise ukungqubuzana phakathi kwevalvu nepayipi.
11. Ungayinyatheli intamo yevalvu noma isondo lesandla sevalvu.
12. Ungafaki i-DN350 noma ama-valve amakhulu abheke phansi.
13. Ungawafaki amavalvu ovemvane ngokuqondile kumavalvu okuhlola noma amaphampu ngoba lokhu kungase kubangele umonakalo lapho uthinta ipuleti levalvu.
14. Ungawafaki amavalvu ohlangothini olungezansi lomfula lwendololwane kanye namashubhu anyakazayo, noma ulinganise amavalvu lapho amazinga okugeleza eshintsha.Kulokhu, kutuswa ukufaka ivalvu ebangeni eliphindwe cishe izikhathi eziyishumi ubukhulu be-valve.
15. Ukufakwa kwevalvu kudinga ukucabangela ukuthi iyiphi idiski ezothola izinga lokugeleza kanye nengcindezi ngesikhathi sokudluliselwa koketshezi.
