I-China High Performance Pneumatic Welded Three-piece Ball Valve - Ukulawula Okunembile Nokubekwa uphawu Okuthembekile
Le valve ye-pneumatic welded yezingxenye ezintathu zebhola esebenza kahle kakhulu iklanyelwe ukuhlinzeka ngokusebenza okuhle kakhulu kokulawula kanye nomphumela wokuvala oqinile, ofaneleka ngokukhethekile izinhlelo zokusebenza zezimboni ezidinga ukulawulwa kokunemba okuphezulu nokuthembeka okuphezulu. Isakhiwo esineziqephu ezintathu sale valve yebhola siqinisekisa amandla aphezulu esakhiwo nokubekwa uphawu okungcono. I-welding end connection ihlinzeka ngendlela yokuxhumana eqinile futhi ezinzile, elungele izinhlelo zokusebenza lapho kudingeka khona isevisi yesikhathi eside engavuzi. I-pneumatic drive mechanism inika amandla ukuphendula okusheshayo nokulawula kude, ikwenze kube ukukhetha okuhle kwezinhlelo ezizenzakalelayo kanye nezinhlelo zokusebenza zokushintsha imvamisa ephezulu.
Amapharamitha wobuchwepheshe:
1. Ububanzi obujwayelekile: DN15 - DN300 (ingenziwa ngokwezifiso uma kudingeka).
2. Ingcindezi yokusebenza: Ngokwezicaciso ezihlukene, ngokuvamile i-1.6mpa kuya ku-6.4mpa (inani elithile lidinga ukubhekisela kudatha yobuchwepheshe enikezwe umenzi).
3. Izinga lokushisa elisebenzayo: -20 ℃ ukuya ku-+232 ℃, kuya ngempahla ekhethiwe kanye nenhlanganisela yophawu.
4. Ukusebenza kwevalvu: i-pneumatic, i-actuator ebambekayo kabili noma eyodwa.
5. Isignali yokulawula: isignali evamile ye-4-20ma yamanje noma isignali yokucindezela komoya.
6. Ukulawula ukugeleza: okunembayo, kungalungiswa ngamanani amancane, afanele izikhathi lapho inani le-CV lilawulwa khona ngokunembile.
7. Imidiya esebenzayo: amanzi, igesi, uwoyela, amakhemikhali, njll.
8. Imodi yokulawula: ingalungiswa njengohlobo lokushintsha, uhlobo lokulawula noma uhlobo lokulinganisa.
9. Imodi ye-Interface: izesekeli ezahlukene zikagesi noma ze-pneumatic zingakhethwa ukuze zivumelane nezinhlelo zokulawula ezahlukene.
Imininingwane nosayizi:
1. Imodi yokuxhuma: uxhumano lwe-butt welding, izilinganiso zokuphela-kuya-ekupheleni zihambisana nezindinganiso zokukhiqiza ezihambisanayo.
2. Izinga le-Flange: lingenziwa ngokuhambisana namazinga omhlaba afana ne-ANSI/ASME, i-DIN, i-JIS, njll.
3. Ubude besakhiwo: ngokuhambisana nezindinganiso ezifanele zokuqinisekisa ukuguquguquka nokushintshashintsha kokufaka.
4. Qeda uxhumano: ukuphela kwe-welding ukuze kuqinisekiswe ukuqina nokuqina kokuxhumeka kwepayipi.
5. Impahla yomzimba ye-valve: insimbi engagqwali, insimbi ye-carbon noma ezinye izinto ze-alloy ukuhlangabezana nezidingo zezimo zokusebenza ezahlukene.
6. Izinto zebhola: insimbi engagqwali, i-carbon steel noma ezinye izinto ze-alloy, ezingase ziphathwe ngokukhethekile ukuze kuthuthukiswe ukuqina.
7. Izinto zokufaka uphawu: ptfe, ppr, metal seals, njll. ukuqinisekisa ukusebenza kokuvala ngaphansi kwezingcindezi ezihlukahlukene namazinga okushisa.
Amapharamitha wobuchwepheshe angenhla kanye nokucaciswa kungokwereferensi kuphela, njengoba amapharamitha nobukhulu bomkhiqizo wangempela kuzohluka kuye ngomkhiqizi kanye nezidingo zohlelo lokusebenza. Lapho uthenga amavalvu ebhola aneziqephu ezintathu zepneumatic asebenza kahle kakhulu, kufanele kukhulunywe nomkhiqizi ngokuningiliziwe ukuze kutholwe ulwazi lomkhiqizo olunembile kanye nedatha yobuchwepheshe.
