Nta:
1.Thov- tawm pov thawj qia
Rau lub hom phiaj ntawm kev tiv thaiv lub qia los ntawm ya tawm uas tshwm sim nyob rau hauv txawv txav ntawm lub puab siab ntawm lub valve, lub xub pwg nyom yog tsau nyob rau hauv qis ib feem ntawm lub qia. Tsis tas li ntawd, nyob rau hauv thiaj li yuav tiv thaiv kom tsis txhob tshwm sim los ntawm burnout ntawm packing txheej ntawm lub qia nyob rau hauv lub qhov. hluav taws kub, thrust bearing yog teem rau ntawm qhov chaw sib cuag ntawm lub xub pwg nyom ntawm qis qis ntawm qia thiab lub cev valve. Yog li lub rooj zaum rov qab yog tsim uas yuav tiv thaiv kom tsis txhob muaj kev sib tsoo.
2. Lub xauv xauv
Cov ntsuas phoo tuaj yeem siv los ntsuas lub ntsuas phau ntawv thaum nws qhib lossis kaw tag nrho txhawm rau tiv thaiv cov neeg ua haujlwm tsis yog - rub tus kov uas yuav ua rau lub valve tsis ua haujlwm. Nws tseem tuaj yeem zam kev qhib lossis kaw ntawm lub valve uas tshwm sim los ntawm kev poob siab los ntawm cov kav dej lossis cov yam ntxwv tsis tuaj yeem ua rau muaj kev sib tsoo. Rau cov kav dej ua haujlwm xws li cov roj hluav taws kub thiab tawg, roj thiab tshuaj lom neeg nruab nrab, lossis rau qhov chaw kav dej, qhov ntsuas qhov ntsuas qhov ntsuas yog qhov tshwj xeeb.
3.Anti- hluav taws xob zoo tsim
Thaum lub trunnion pob valve siv ib txwm, nws kaw los ntawm lub rooj zaum thiab lub pob saum npoo, lub rooj zaum tuav kaw los ntawm O-ntiv nplhaib thiab lub cev, qhov no yog mos kaw thiab txhim khu kev qha sealing. Thaum lub rooj zaum thiab O-nplhaib raug hlawv, lub rooj zaum thiab lub cev yuav raug kaw los ntawm kev nthuav dav graphite. Yog li ua los tiv thaiv - hluav taws muaj kev nyab xeeb lub hom phiaj.
4.Anti- khoom siv zoo li qub
Txhawm rau tiv thaiv kev sib txhuam ntawm pob, qia thiab PTFE uas tsim hluav taws xob zoo li qub uas yuav ua rau cov khoom tawg thiab cov khoom tawg uas ua rau muaj kev sib tsoo, hauv lub pob valve no, static- conduction caij nplooj ntoos hlav yog teem rau ntawm qia thiab pob, qia thiab lub cev. Yog li hluav taws xob zoo li qub tau ua rau hauv av thiab kev ruaj ntseg ntawm qhov system.
5.Free to ntawm lub cev Sealed siv
Txoj hauj lwm txuas ntawm lub cev lub cev thiab lub kaus mom yog muab ob npaug los ntawm gasket thiab O-nplhaib, ntawm lub hauv paus no, xws li hluav taws kub, kub siab, poob siab thiab tsis sib luag qhib lossis kaw ntawm lub torque tag nrho tsis tuaj yeem cuam tshuam rau sab nraud.
6. Ob chav blockbleed (DBB)
Thaum lub pob qhib tag nrho lossis kaw txoj haujlwm, 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 khoob khoob khoob .
7. 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. Lub kaw lus zais tau muab tso rau hauv ib sab ntawm txhua qhov sib xyaw ua ke kom tiv thaiv kev sib txuas los ntawm kev ntws tawm vim qhov kev txiav txim ntawm cov khoom xa tawm. Sab saum toj ntawm qhov sib xyaw ua ke valve yog qhov txuas rau kev sib txuas ceev nrog rab phom sib xyaw.
8.Tsis siv neeg lub cev kab noj hniav nyem
When the body pressure going up un-normally as the unstable factor,the trunnion ball valve downstream seat will be pushed by unnormal pressure,and the release the un-normally pressure automatically, it doesn't damage to the sealing of upstream seat.
