Sab saum toj nkag pob Valve

NSV TOP ENTRY BALL VALVE yog siv rau hauv cov raj xa dej thiab kev lag luam thiab nws muaj kev nkag mus rau sab saum toj thiab ntawm kab kev ua haujlwm.Nws muaj ntau yam zoo, xws li cov kua dej me me, cov qauv yooj yim, ntim me me, lub teeb yuag, txhim khu kev qha saaling, yooj yim rau kev khiav lag luam thiab kev txij nkawm, qhib thiab kaw sai, nrog rau pib thiab kaw yooj yim.

1.Ib thooj lub cev
Ib thooj lub cev yog siv rau lub cev kom lav txaus lub zog thiab rigidity nyob rau hauv siab tshaj plaws nyob rau hauv kev khiav hauj lwm siab.Lub sab hauv ntawm lub valve yog ua tib zoo tsim thiab xaiv los xyuas kom meej kev cia siab nyob rau hauv tag nrho cov hom ntawm kev khiav hauj lwm mob.Ntau margin phab ntsa thckness thiab adaptation ntawm siab zog connective bolts yog yooj yim rau valve maitenance thiab txaus los txhawb kev ntxhov siab los ntawm cov kav dej.

2. Sab saum toj nkag
Nws qhov sib txawv tshaj plaws los ntawm cov pob valve yog tias nws cov kev saib xyuas tuaj yeem ua rau ntawm cov yeeb nkab kab thiab tsis muaj qhov cuam tshuam los ntawm cov yeeb nkab kab.Lub rooj zaum rov qab yog siv rau lub rooj zaum thiab lub nraub qaum ntawm lub rooj zaum yog oblique lub kaum sab xis kom tiv thaiv kev sib tsoo ntawm impurity. los ntawm kev cuam tshuam qhov chaw ntawm lub rooj zaum.

3. Tsawg ua haujlwm torque
NSV sab saum toj nkag series pob valve muaj lub trunnion mounted pob, uas nto yog av, polished thiab tawv ntsej muag kho.Lub pob thiab qia yog kev, zawv zawg bearings yog ntsia rau sab nraud bore kom cov kev sib txhuam vojvoog me me thiab kev ua haujlwm torque yog heev. qis.

4. Thaum muaj xwm ceev sealing
Cov qhov sib xyaw ua ke yog tsim thiab cov tshuaj txhaj tshuaj sib xyaw tau muab tso rau ntawm qhov chaw ntawm qia / lub hau thiab lub cev txhawb nqa ntawm sab valve.Thaum sealing ntawm qia los yog lub rooj zaum raug puas tsuaj rau induce to, lub compound yuav siv tau los ua lub thib ob lub sij hawm sealing.A concealed check valve yog ntsia nyob rau hauv ib sab ntawm txhua compound txhaj valve los tiv thaiv compound los ntawm tawm ntws vim qhov kev txiav txim ntawm transmitter khoom.Lub sab saum toj ntawm compound txhaj valve yog lub connector rau ceev kev twb kev txuas nrog compound txhaj phom.

5. Txhim khu kev sib khi
Lub rooj zaum sealing yog tsim los ntawm lub rooj zaum sealing thiab hlau retainer tivthaiv.Lub rooj zaum retainer floats axially thiab tsis tshua muaj siab sealing ntawm lub rooj zaum valve yog mus txog los ntawm lub siab ua ntej lub caij nplooj ntoos hlav. Tsis tas li ntawd, cov nyhuv piston ntawm lub rooj zaum valve yog tsim tsim nyog, uas pom tau tias siab. siab sealing los ntawm lub siab ntawm kev khiav hauj lwm nruab nrab thiab paub qhov cuam tshuam ntawm retainer los tsim lub sealing ntawm lub cev.Lub expansion graphite nplhaib yog tsim los kom paub sealing nyob rau hauv hluav taws kub.

6. Ob chav thaiv & ntshav (DBB)
Thaum lub pob qhib tag nrho lossis kaw qhov chaw, cov khoom xa tawm hauv nruab nrab ntawm lub cev tuaj yeem tso tawm los ntawm cov kua dej thiab cov khoom siv khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob .

7.Anti-static thiab hluav taws kev nyab xeeb tsim
Kev tiv thaiv hluav taws tsim ntawm lub valve ua tau raws li qhov yuav tsum tau ua hauv API6FA / API607 tus qauv thiab cov qauv tsim los tiv thaiv zoo li qub raws li cov cai hauv API6D thiab BS5351.

8.Extension qia
Rau lub hauv av ntsia lub valve, lub qia tuaj yeem ua kom ntev thiab kom yooj yim ntawm kev ua haujlwm, cov khoom siv sib xyaw ua ke thiab cov kua dej tuaj yeem txuas mus rau sab saum toj ntawm lub valve.

9. Ntau hom kev tsav tsheb
Lub ncoo sab saum toj ntawm lub valve tsim raws li ISO 5211, uas yog yooj yim rau kev sib txuas thiab kev sib pauv ntawm ntau yam tsav tsheb.Cov hom kev tsav tsheb yog phau ntawv, hluav taws xob, pneumatic thiab pneumatic / hydraulic.
