Cov ntsiab lus tseem ceeb ntawm API 609 tus qauv suav nrog ob-flanged, lug-type, thiab wafer npauj npaim valve tsim. Tus qauv no txhais:

1. Cov Kev Cai Tsim Qauv:Kev ua kom zoo dua ntawm cov kua dej dynamics rau qhov tsis kam ntws tsawg kawg nkaus thiab kev tswj hwm meej.

2. Khoom Siv & Kev Tsim KhoomCov Lus Qhia Tshwj Xeeb rau lub cev valve, discs (npauj npaim phaj), stems, thiab seals.

3. Cov Txheej Txheem Kev Ntsuas:Yuav tsum muaj kev ntsuam xyuas siab, kev sib khi, thiab kev ntws kom paub tseeb tias zoo.

4. Cov Lus Qhia Txog Kev Txij Nkawm:Cov txheej txheem rau kev tshuaj xyuas, lubrication, thiab kho.

Npauj Npaim Valves Ua Haujlwm Li Cas

A lub valve npauj npaimLub disc tig 90° ncig nws lub axis los tswj kev ntws. Cov yam ntxwv tseem ceeb:

•Txoj Haujlwm Qhib: Lub disc sib luag rau qhov ntws (qhov siab poob tsawg kawg nkaus).

•Txoj Haujlwm Kaw: Lub disc perpendicular rau qhov ntws (lub npuas-nruj kaw).

•Kev ua haujlwmSiv cov tes tuav tes, cov iav tsav, lossis cov tshuab ua haujlwm tsis siv neeg (pneumatic/electric).

Cov Cheebtsam Tseem Ceeb ntawm Cov Npauj Npaim Valves

1. Lub cev valve

Tsim qauv cylindrical me me; muaj nyob rau hauv wafer, lug, lossis flanged styles.

2. Disc (Phaj)

Phaj nyias, voj voog (stainless hlau feem ntau) rau kev tswj kev ntws.

3. Qia

Lub zog siab txuas lub disc rau lub actuator.

4. Lub Rooj Zaum (Kev Sib Nqus)

EPDM, PTFE, lossis cov rooj zaum hlau rau kev ua haujlwm tsis muaj qhov xau.

5. Tus ua haujlwm

Kev tsav tsheb siv tes, pneumatic, hydraulic, lossis hluav taws xob.
