1. Pom kev tshuaj xyuas
Valve lub cev thiab sealing soj ntsuam
Soj ntsuam ncaj qha seb puas muaj cov xuab zeb uas muaj qhov tsis xws luag, khij cov pob zeb ntawm cov khoom sib tw (carbide / stainless hlau khoom), thiab paub meej tias tsis muaj khawb, hnav lossis deformation;
Siv endoscope lossis tsom rau kev pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau kom tsis txhob muaj peev xwm pom tau tias tsis muaj qab hau.
2. Cov tshuaj ntsuam zoo li qub
Kev Kuaj Hydraulic
Tom qab kaw lub valve, txuas nws mus rau qhov kev sim tshuaj, sau rau dej thiab siv lub siab rau {4}
Tsom rau kev kuaj xyuas cov tole ntawm cov flange kev txuas, valve kav stuffing box thiab valve lub cev vuam qhov chaw.
Cua Siab Test
Siv cov cua compressed los yog nitrogen raws li nruab nrab, nias nws mus rau 1.1
Siv tau rau cov haujlwm ua haujlwm uas zam kev zam cov dej xov xwm lossis xav tau los xyuas cov dej xau me me.
3. Kev Tshawb Nrhiav Kev Zoo
Hloov kev ua haujlwm thiab kev nrhiav tau
Qhib thiab kaw lub valve rov qab (ntau dua los yog sib npaug rau 1 0} 0 lub sij hawm
Siv cov ntsuas dej ntws los saib xyuas cov nyiaj seem ntawm nruab nrab hauv lub xeev kaw kom pom tseeb tias kev sib khi saum npoo hlau haum tus qauv.
Siab dhau kev siab ntsuas kev ntsuas
Ua 5-10} nrawm nrawm siab nce / kev tawm tsam kev nce qib (xws li PN16 ~ PN64) kom pom tias kev sib khi ua haujlwm txo qis vim lub siab poob siab.
4. Cov khoom siv ua tau zoo
Hardness thiab Tshuaj Siv Tshuaj Ntsuam Xyuas
Ua pob zeb hardness ntsuas ntawm cov chaw sib khi (nyuaj alloy yuav tsum muaj ntau dua los yog sib npaug ntawm HRC60) kom ntseeg tau tias cov kev coj tawm tsam cov haujlwm ua haujlwm;
Siv lub tshuab hluav taws xob txhawm rau txhawm rau ntes cov muaj pes tsawg leeg ntawm cov hlau sealing (xws li tungsten carbide, 316 stainless hlau) kom tshem tawm cov ntaub ntawv tsis ua haujlwm tshwm sim los ntawm cov ntaub ntawv substing.
Corrosion Kuj Xeem
Rau acidic lossis siab-ntsev medoo, uas nyob hauv lub valve nyob rau hauv kev sim nruab nrab rau 72 teev kom pom tias tus corrosion tus nqi ntawm kev sib khi saum toj tshaj li {2}}. 1mm / xyoo.
V. LWM YAM KEV PUAM XYUAS
Tsawg kub / siab qhov kub hloov tau
Ua kev sib khi ntawm kev sib khi ntawm huab cua sov ntawm -40 degree lossis 425 Qib los xyuas qhov sib xws ntawm cov khoom sib xyaw nrog lub cev sib khi;
Cov kev mob siab xav tau kev tshuaj xyuas ntxiv ntawm cov oxidation thiab decarburization ntawm kev sib khi saum npoo.
Torque thiab kev ua haujlwm quab yuam kom pom
Siv lub zog ua haujlwm los ntsuas qhov qhib thiab kaw lub zog. Yog tias nws ntau tshaj tus qauv tsim (xws li DN50 valve tsawg dua lossis sib npaug nrog 50 lab tseem ceeb ntawm kev hnav khaub ncaws lossis sib dhos ua ke ntawm cov chaw sib dhos.
Cov Qauv Txuj Ci thiab Kev Txiav Txim
Cov tshuaj tolectional: Lub siab poob thaum lub siab tso dej / cua siab kuaj yog tsawg dua lossis sib npaug nrog 5%, thiab tsis muaj qhov xau;
Kev Ua Haujlwm Huab Ua Haujlwm Yuav Tsum Tau Ua: Nuclear Fais Fab Nroj Tsuag thiab Lwm Yam Kev Pom Zoo (to
Cov Khoom Siv Khoom Siv: Lub hardness yuam kev ntawm kev sib khi saum toj yog tsawg dua lossis sib npaug ntawm cov tshuaj lom neeg muaj pes tsawg dua lossis sib npaug}. 5%.
Xaiv cov tswv yim: nws yog qhov nyiam siv kev sib xyaw ntawm cov dej siab + Helium huab hwm coj tau mus rau hauv tus account ob qho nqi thiab raug; Dynasam li kev sim siab yuav tsum muaj rau kev ua kom muaj zog lossis cov scenes kub siab.
