Tswv yim
Cov koob Valve zoo tuaj yeem ua haujlwm manually lossis txiav.Manually ua rab koob li qub siv lub tes tuav los tswj qhov kev ncua deb ntawm lub plunger thiab lub rooj zaum valve.Thaum lub handwheel tig mus rau hauv ib qho kev taw qhia, lub plunger yog nqa los qhib lub valve thiab tso cai rau cov kua dej dhau mus.Thaum lub handwheel tig mus rau lwm qhov, lub plunger txav ze rau ntawm lub rooj kom txo qis tus nqi ntws los yog kaw lub valve.
Cov koob txhaj tshuaj tsis siv neeg txuas nrog lub tshuab hydraulic lossis lub tshuab hluav taws xob uas cia li qhib thiab kaw lub valve.Lub cev muaj zog lossis actuator yuav kho lub plunger txoj haujlwm raws li lub sijhawm lossis cov ntaub ntawv kev ua haujlwm sab nraud tau sau tseg thaum saib xyuas cov tshuab.
Ob leeg ua haujlwm manually thiab automated Koob li qub muab kev tswj hwm tus nqi ntws.Lub handwheel yog finely threaded, uas txhais tau hais tias nws yuav siv sij hawm ntau lem los kho txoj hauj lwm ntawm lub plunger.Yog li ntawd, ib rab koob valve tuaj yeem pab koj tswj cov dej ntws zoo hauv lub cev.
Koob Valve nta cov khoom siv thiab cov duab
1. Koob valve
2. Ua los ntawm Stainless hlau ASTM A479-04 (Qib 316)
3.Threaded xaus raws li ASME B 1.20.1 (NPT)
4. Max. Ua Haujlwm Siab 6000 psi ntawm 38 ° C
5. Ua haujlwm kub -54 txog 232 ° C
6.Safety bonnet lock tiv thaiv kev sib tsoo.
7.Rack seating tsim tiv thaiv cov ntim hauv txoj haujlwm qhib tag nrho.
