Lembe ma pire tek mi tic ku check valve utiye ni juku pii ma wok kud i iye, man check valve juyike i dhugola pa pump. Mi medo, check valve umaku juketh i dhugola pa compressor. I lembe ma nok, pi juku mol pa pii ma wok cen, umitu juketh check valve iwi jam tic, jam tic nyo pipeline.
Pol kare, vertical lift check valves jutiyu kudu iwi pipelines ma lac pa 50mm. Straight-through lift check valve jucopo ketho iwi pipelines ma ucungo man ma ucungo. Valve ma piny juyike kende iwi pipeline ma ucungu pa pump inlet, man piny ma iye mol kud piny ni malu.
Swing check valve copu bedu ma tek mandha, PN copu bedu 42MPa, man DN copu bedu malac mandha, ma dit copo tuc 2000mm. Nimakere ku piny matung tung ma juyubu ku shell man seal, ecopu bedu ni piny moko ci ma tiyo man piny moko ci ma tiyo. Piny ma jutiyo kudu utiye pii, lyethu, yamu, piny ma nyayu lyethu, moo, cam, yath, man mange. Lembe ma jutiyo kudu utiye ikind -196~800°C.
Kabedo mi ketho swing check valve epe, pol kare juketho iwi paip ma ucungo, ento ecopu bedu iwi paip ma ucungo nyo ma ucungo.
Kare ma tiyo ku butterfly check valve utiye pressure ma piny man diameter malac, man kare mi ketho valve utiye nok. Pien kero pa tic pa butterfly check valve copo bedu malac ungo, ento diameter pare copo bedu malac akeca, ma copo tuc 2000mm, ento kero pare utiye piny pa 6.4MPa. Butterfly check valve jucopo timo ni wafer type, ma pol kare juketho ikind flanges aryo pa pipeline i ayi pa wafer connection.
Kabedo mi ketho butterfly check valve epe, ecopu bedu iwi paip ma ucungo, paip ma ucungo nyo paip ma ucungo.
Diaphragm check valve ber pi pipelines ma rwinyo pii. Diaphragm copo jwigo pii ma wok kud i mol pa pii. Calu lyethu pa tic man kero pa tic pa diaphragm check valves utiye nok ku piny pa diaphragm, jutiyo kudu pol kare i paip ma lyeth pare nok man ma lyeth pare ber, asaga pi paip pa pii. Pol kare, lyethu pa piny ma tiyo kudu utiye ikind -20~120°C, man kero pa tic utiye piny pa 1.6MPa, ento diaphragm check valve copo nwangu diameter malac, man DN madit copo bedu makadhu 2000mm.
Diaphragm check valve jutiyo kudu lee i oro ma ukadhu eni pi tic pare maber mi gwoko pii, yub pare yot man bey pare ma yot.
Ball check valve utiye ku tic maber mi mako piny, tic maber man rwom maber mi juku nyundo pi pii pien dhugola ne utiye piny ma umu ku rubber; man pilembe seal copo bedu mupira acel nyo mupira madwong, ecopu bedu ma dit. Ento, cinge utiye piny ma oling ma umu ku rubber, ma epe pi paip ma tek tek, ento eber pi paip ma tek man ma piny kende.
Calu ma piny ma jutiyo kudu pi ball check valve juyike ku stainless steel, man hollow sphere pa seal jucopo umu ku PTFE engineering plastic, ecopu bedu ni tiyo kudu i pipelines ku general corrosive media.
Temperature mi tic pa kit check valve eni utiye ikind -101~150°C, pressure ma jukwanu utiye ≤4.0MPa, man diameter ma jukwanu utiye ikind 200~1200mm.
