Umshini wokugoba we-Butterfly uqaphela ukushintsha isimo sokugoba kwesimo

Izinkampani zebhulafuta zebhethile zebhethile zibonisa indlela yokuthuthukisa isitshalo esivaliwe.

Izinkomba ezahlukene zinamathela ezinye izindlela zokutholakala kwepuleti, namuhla ikampani yami ukuthi sithumele indlela yokutholakala kwepuleti.

Izindlela zokutholakala kwepuleti yeglobhu.

I-Globe valve strength test, kuyobaqokwa ekhwalithi yokuqinisekisa, ukufaka i-valve ethunyelwe ekhwalithi yokuqinisekisa, uvule i-valve, ukufaka isici esetshenziswa kwi-value esetshenziswayo, bheka uma i-valve body kanye ne-valve cover ikhala kanye nokuhlanzwa. Kungenzeka futhi ukwenza i-strength test yomunye. I-sealing test ikwenziwe kuphela izindlela zeglobe valves. Qiniseka i-valve stem yeglobe valve ekwenzeni isitatimende esivertical, i-valve ivulekile, isici esetshenziswa kusukela ekhishini lwe-flap lwe-valve end of the introduction kwi-value esetshenziswayo, bheka i-packing kanye ne-gaskets; uma kwenziwe okwethu ukuvula i-valve flap, ivule i-end engezansi ukuze bheka uma kukhona okuhlanzekile. Uma i-valve strength kanye ne-sealing test kufanele kwenziwe, ungakwazi ukwenza i-strength test ngaphambi kokushayela ekhwalithi yokuqinisekisa, futhi uthi ukushayela ekhwalithi yokuqinisekisa kwi-value, bheka i-packing kanye ne-gaskets; futhi uthi uvule i-valve flap, ivule i-end elinye ukuze bheka uma kukhona okuhlanzekile.

Izindlela zokuthuthukisa i-pressure test ye-ball valve

I-Pneumatic ball valve strength test kufanele kube ekwenzeni ekubonakaliseni kwezinkomba ezimbili.

Izincwadi zokubeka isibhakela esihambisana: isibhakela esiphakathi, isithombe esisha esikhishwe ngokushesha, isinyathelo esisodwa esisiza ukuthola izinto zokuhamba, isinyathelo esinye esisodwa esisiza ukuthola izinto zokuhamba; kuyobaqala isibhakela ngemva kokuhamba isibhakela, isinyathelo esisodwa esisiza ukuthola izinto zokuhamba, kanti kuyobaqala isibhakela ngemva kokuhamba isibhakela, isinyathelo esisodwa esisiza ukuthola izinto zokuhamba.

　　② fixed ball valve sealing test: before the test will be unloaded ball rotation several times, fixed ball valves in the closed state, from one end of the introduction of the test medium to the specified value; with a pressure gauge to check the introduction of the end of the sealing performance, the use of the pressure gauge accuracy of 0.5 ~ 1 level, the range of the test pressure of 1.6 times. In the specified time, there is no pressure drop phenomenon is qualified; and then from the other end of the introduction of test media, repeat the above test. Then, the valve in a half-open state, closed at both ends, the inner cavity is full of media, under the test pressure to check the packing and gasket, there shall be no leakage.

Izinkomba zezinkomba ezintathu kumele zibe kuhlelwe ekuboniseni.

3. Iphuzu lokuvula isitayela sebhabheli yokudonsa kwezinkinobho

Ukubhekwa kwesifiso sokwenza isitshalo sebhaqwa sebhaqwa kuyadingeka njengoba kwezinye izinto ezisebenzayo. Ukubeka isifiso sokuphikisana kwesibhakela sebhaqwa kufanele kube kusungulwe ekupheleni kwesikhathi sokuphikisana, isibhakela kufanele kube sivulekile, isinyathelo esinye kufanele kube sivulekile, kube kushaywe isipresha ekwenzeni isetshenziswa; bheka ukuphakama kwezinto ezisebenzayo kanye nezinyathelo ezifuna ukuphikisana, vala isibhakela, vula isinyathelo esinye, bheka ukuphikisana kwesibhakela uma kungekho ukuphikisana okungase kwenziwe. Isibhakela sebhaqwa njengoba isetshenziswa njengoba isebenza mayelana nokuphikisana kwesibhakela.

4. Iphuzu lokubheka isitayela sokuphefumula sidlulela kwezinkinobho

Izinto zokubonisa ukunquma kwesikhumba sokuphefumula kwezinkomba zokuphefumula kusuka endaweni yokuqala yomkhumbi, vula isikhumba sesivale, isinyathelo esinele kususwe, isibonelo esisiza isibonelo esisiza. Emva kwalokho, qinisa ukuphefumula kusikhumba sokuphefumula, vala isikhumba sesivale, vula isinyathelo esisiza, isibonelo esisiza.

5. Iphuzu lokuhlola isicelo sokuphepha sokuhlola kwezinkomba

Izinkomba zokuhlola izinkomba: isitsha sokuqhuba isitsha isitsha isikhala esisodwa esisodwa kwezindlela ezihlukile; isitsha sokuqhuba isitsha isitsha isikhala esisodwa esisodwa kwezindlela ezihlukile kwezindlela ezihlukile.

Ukubonisa ubunzima, kusuka endlini yokungena kwesitayela sokwenza imidwe kuya ekhethwe, isinyathelo esinye sivalelwe ukuze kube okwenziwe.
