Stainless Hlau Globe Valves Nta thiab cov txiaj ntsig:
1. Cim tsis-rotating qia tsim yog yooj yim adaptable rau actuation-- nrog precision Acme threads thiab burnished tiav.Stainless hlau Valve haum rau kab rov tav installation.
2. Stainless Steel Universal trim: 13Cr qia, 13Cr ntsej muag disc, thiab CoCr alloy ntsej muag rooj zaum- API Trim 8 haum rau kev pabcuam txog 850 F (454 C).Lub ntsej muag lub ntsej muag CoCr alloy hardfaced, hauv av, thiab lapped rau daim iav tiav.Conical lub rooj machined kom zoo nto tiav.Lub cev qhia disc kom raug sib koom ua ke ntawm qhov nyuaj ntawm lub disc (hardfaced nrog 13Cr, CoCr alloy, SS 316, lossis Monel) nrog rau saum npoo ntawm lub cev lub rooj, uas yog hauv av thiab lapped rau daim iav tiav.Cov ntawv qhia disc yog hardfaced kom ntev lub neej ntawm cov disc guides.
3. Stainless hlau lub cev thiab lub kaus mom hlau casting yog precision machined.Ib-thooj lub kaus mom rau kev sib dhos zoo dua, tsawg qhov chaw.
4. Stuffing lub thawv machined kom zoo nto tiav.
5. Lub cev thiab lub kaus mom sib koom ua ke kom raug machined kom zoo nto tiav.Ncua ntim gasket.
6. Lub caj pas muaj ob-thooj kev tsim kho kom yooj yim sib dhos.
7. Rotating qia txiv ntoo hauv Austenitic ductile hlau Gr.D-2C, txuas ntxiv rau hauv kab.
8. Torque caj npab txo qhov hnav ntawm lub nplhaib ntim thiab ua kom muaj kev sib khi zoo dua thiab txo cov torque.
9. Impactor handwheels: Lub ntiaj teb thiab nres cov tshev valve yuav tsum tau kaw lub zog siab dua li lub rooj vag li qub nrog tib lub rooj zaum txoj kab uas hla thiab cov chav kawm siab.Qhov kev lag luam yooj yim tshaj plaws rau kev kaw ntom nti yog qhov cuam tshuam ntawm tes.Ob lub lugs cam khwb cia nyob rau hauv lub log ntaus ib txhij tshuab thiab muab 3 - 10 lub sij hawm kaw quab yuam ntawm standard handwheels.Impactor handwheels yog muab los ntawm cov chaw tsim khoom xaiv tshwj tsis yog cov neeg siv khoom tau teev tseg.
10. Flanges: ASME Chav Kawm: 150-- 300: 116" tsa ntsej muag.
11. ASME Chav Kawm: 600-- 1500: 1/4" tsa ntsej muag.
