Iyini i-Solvent Weld Ball Valve
A ivalvu yebhola yokushisela ye-solventisebenzisa ukubopha kwamakhemikhali okuhlanganisa esikhundleni sokushisela okushisa ukuze ixhume unomphela izingxenye zamavalvu ezinhlelweni zamapayipi. Ngokungafani namavalvu endabuko ashiselwe, ukushisela kwe-solvent kuncibilikisa izendlalelo ezingaphezulu zezinto ze-PVC/CPVC, okudala amalunga angavuzi ngokusebenzisa ukubopha kwama-molecule.
Izici Eziyinhloko Zesakhiwo
– Ukwakhiwa okungenawo amanzi: Ukuhlanganiswa kwamakhemikhali kudala ukuxhumana kwe-monolithic
– Ukumelana nokugqwala: Kulungele imithombo enamandla (ama-asidi, izinyibilikisi)
– Umklamo ongadingi ukulungiswa: Amalunga ahlala njalo aqeda ukuwohloka kwesivalo
– Ukufakwa okuncane: 40% kulula kunezinye izindlela ezifakwe i-flange
– Ukugeleza okugcwele: Ukwehla okuncane kwengcindezi emapayipini
Izinhlelo Zokusebenza Eziyinhloko
1. Ukucubungula Amakhemikhali: Imigqa yokudlulisa i-HCl, i-H₂O₂, kanye ne-solvent
2. Ukwelashwa Kwamanzi: Izinhlelo ze-chlorination kanye namayunithi okuhlunga
3. Imithi: Ukuphathwa koketshezi okuhambisana ne-USP Class VI
4. Ukukhiqizwa Kwe-semiconductor: Ukusatshalaliswa kwamanzi amsulwa kakhulu
Ukushisela Kwe-solvent vs. Ukushisela Kwendabuko
| Isici | Ukushisela kwe-solvent | Ukushisela Okushisayo |
| Indlela Yokuxhuma | Ukuhlanganiswa kwamakhemikhali | Ukuncibilika kwensimbi |
| Ukuhambisana kwezinto ezibonakalayo | I-PVC/CPVC kuphela | Izinsimbi kanye nama-alloy |
| Ukumelana Nokushisa | 60°C (140°F) ubuningi | 400°C+ (750°F+) |
| Ikhono Lokufaka | Ukuqeqeshwa okuphansi kuyadingeka | Kudingeka umshiseli oqinisekisiwe |
I-NSW: Umkhiqizi Wevalvu Yebhola Eliwelding Elithembekile
NjengomuntuIsitifiketi se-API 6Dumenzi we-valve yebhola ehlanganisiwe, i-NSW iletha:
–Ububanzi obuphelele bosayiziAmavalvu ebhola le-weld le-solvent angu-½” kuya ku-60″
–Izilinganiso zokucindezela: Ibanga 150 kuya ku-900
–Izinketho zezinto ezibonakalayo: Ukwakhiwa kwe-PVC, CPVC, PP, kanye ne-PVDF
–Imiklamo ekhethekile:
– Iziphambukisi Zezindlela Ezi-3
– Izinhlobo eziphephile emlilweni (API 607)
– Amamodeli e-Cryogenic (-196°C)
– Ama-actuator e-ISO 5211 alwa nokungaguquguquki
*Ukuqonda Kwemboni*: Ama-valve okushisela okunyibilikisayo abusa u-78% wezinhlelo zamapayipi e-PVC amakhemikhali aseNyakatho Melika ngenxa yezivalo zawo zokukhipha ukungcola kanye nempilo yenkonzo yeminyaka engu-25 (ehambisana ne-ASME B31.3).
