Ama-valve okuxhuma ane-plunger emise okwekhoni abizwa ngokuthi ama-plug valve. Ngokuzungezisa amadigri angu-90, imbobo yokudlula kupulaki ingavulwa noma ivalwe, iyihlukanise nembobo yokudlula emzimbeni wevalvu. Ama-valve ama-plug avula ngokushesha futhi avale ngokushesha ngama-valve avamise ukusetshenziswa kumapayipi aphakathi nendawo anezinga lokushisa eliphansi adinga ukuvulwa nokuvalwa okugcwele ngesikhathi esifushane. Ukumbiwa kwezizinda zikawoyela, ukukhiqizwa kwezinto zokuhamba nokucwengisiswa kwazo, izimboni zamakhemikhali nezephethiloli, ukukhiqizwa kwegesi kanye negesi ye-petroleum ewuketshezi, umkhakha we-HVAC, kanye nezimboni ezijwayelekile konke kukusebenzisa kakhulu. Okwesibili, ama-valve amapulaki angasetshenziswa ukuthutha uketshezi oluqukethe izinto eziqinile ezimisiwe nezinhlayiya. Izinto eziqukethe i-crystal zingathuthwa kusetshenziswa i-valve yepulaki eqondile enesakhiwo sejakhethi evikelayo.
Okulandelayo yizici ezibalulekile zokuklama ze-valve yepulaki ye-JLPV:
1. Idizayini eqondile ivumela ukushintshwa okusheshayo, ukumelana noketshezi oluphansi, nokusebenza kwe-engeli esheshayo yokushaywa unhlangothi.
2. Kunezinhlobo ezimbili zezimpawu: izimvu zamanzi ezithambile nezinsimbi zikawoyela.
3. Kunezinhlobo ezintathu zesakhiwo: ukuphakamisa, i-ferrule, kanye ne-inverted.
4. Idizayini ephephile, ukwakhiwa kwe-anti-static, kanye nokusetshenziswa.
5. Akukho mkhawulo esiqondisweni sokufaka futhi imidiya ingageleza ngezindlela ezimbili. Ukusetshenziswa kanye nokugcinwa kwe-inthanethi kusebenza kakhulu.
Ibanga le-JLPV plug valve design limi kanje:
1. Usayizi: 2” kuya ku-14” DN50 kuya ku-DN350
2. Ingcindezi: Ikilasi 150lb ukuya ku-900lb PN10-PN160
3. Material: carbon steel, insimbi engagqwali nezinye izinto ezivamile metal.
I-NACE MR 0175 anti-sulphur kanye nezinto zensimbi ezilwa nokugqwala.
4. Ukuxhumana kuyaphela: ASME B 16.5 ebusweni obuphakanyisiwe(RF), Ubuso obuyisicaba(FF) kanye Nokuhlanganiswa Kohlobo Lwendandatho (RTJ）
I-ASME B 16.25 esiphethweni esiyisikulufu.
5. Ubukhulu bobuso nobuso: buvumelana ne-ASME B 16.10.
6. Izinga lokushisa: -29℃ ukuya ku-580℃
Ama-valve e-JLPV angafakwa ama-gear operator, ama-actuator womoya, ama-hydraulic actuators, ama-actuator kagesi, ama-bypasses, izinto zokukhiya, ama-chainwheel, iziqu ezinwetshiwe nokunye okuningi kuyatholakala ukuze kuhlangatshezwane nezidingo zamakhasimende.
