nung nukarin la magagamit deng check valves

Ing sangkan ning pamangamitcheck valvepara aiwasan ing pamagbaliktad ning medium, ampo ingcheck valvekeraklan maka-install ya keng outlet ning pump. Dagdag pa, metung acheck valvemaka-install ya keng outlet ning compressor. king makuyad a salita, para aiwasan ing pamagbaliktad ning medium,check valvesdapat i-install ya keng gamit, devices o pipelines.

Keraklan, ing pamag-angat patayocheck valvesmepili la kareng pahalang a pipeline a maki nominal a diametru a 50mm. Diretsu-pamag-angatcheck valvesmalyari yang i-install keng horizontal ampo vertical a linya. Ing foot valve keraklan maka-install ya keng vertical a linya ning pump inlet, at ing medium mamagus ya manibat lalam papunta babo.

Ingswing check valvemalyari yang gawan keng matas a pressure, PN anggang 42MPa, ampo ing DN malyari ya namang maragul, anggang maigit 2000mm. Depende keng materyales ning bale ampo reng seal, nanu mang working medium ampo nanu mang operating temperature range malyari yang gamitan. Ing medium yapin ing danum, steam, gas, corrosive medium, oil, pamangan, panulu, atbp. Ing operating temperature range ning medium atyu ya pilatan ning -196~800°C.

Swing check valvesmalyari lang i-install kareng alang limitasyun a lugal at keraklan maka-install la kareng horizontal a gulis, pero malyari la muring i-install kareng vertical o maka-inclined a linya.

Ingbalbula ning parulmasanting ya para keng mababang pressure ampo maragul a diametru, ampo ing sitwasyun ning pamag-install limitadu ya. uling ing pressure ning obra ningbalbula ning parule malyaring masyadung matas, pero ing nominal diameter malyari yang maragul, malyari yang miras maigit 2000mm, pero ing nominal pressure mas mababa ya keng 6.4MPa. Ingbalbula ning parulmalyari yang gawang pair clamp type, na keraklan maka-install ya pilatan da reng adwang flanges ning pipeline, at gamitan ne ing porma ning pair clamp connection.

Ingbalbula ning parulmalyari yang i-install keng alang limitasyun a posisyun ampo malyari yang i-install keng horizontal, vertical o inclined a linya.

Diaphragmcheck valvesmasanting la kareng pipeline na prone keng water hammer, ampo ing diaphragm malyari yang ilako ing water hammer nung ing medium mamagus ya laban keng danum. Uling ing temperatura ning obra ampo ing pressure ning diaphragmcheck valveslimitadu la kareng materyales a diaphragm, keraklan magagamit la kareng low-pressure normal a temperaturang pipeline, lalu na para kareng pipeline ning danum. Keraklan, ing temperatura ning medium atyu ya pilatan ning -20~120°C, at ing pressure ning obra <1.6MPa ya, pero ing diaphragmcheck valvemalyari yang mika mas maragul a caliber, at ing DN malyari yang miras maigit 2000mm.

Diaphragmcheck valvesmas megamit la kareng milabas a banua uling keng karelang masanting a waterproof performance, medyu simple ing istruktura ampo mababang gastus keng pamaglalang.

Bolacheck valveuling ing seal metung yang bola a makabalut keng goma, inya masanting ing pamag-seal, ing operasyun mapanalig ya, ampo ing water shock resistance masanting ya; At uling ing seal malyari yang metung a bola, o malyari yang gawang dakal a bola, inya malyari yang gawang maragul a diametru. Makanyan man, deng seal na ila reng hollow spheres a makabalut keng goma, na e masanting para kareng high-pressure pipelines, masanting lamu para kareng medium ampo low-pressure pipelines.

uling ing materyales ning bale ning bolacheck valvemalyari yang gawa keng stainless steel, ampo ing hollow ball ning seal malyari yang i-coat keng PTFE engineering plastic, malyari ya namang gamitan keng pipeline ning general corrosive media.

Ing temperatura na ning check valve ayni pilatan ning -101~150°C, ing nominal pressure na ≤4.0MPa, ampo ing nominal diameter range pilatan ning 200~1200mm.
