7. Cov teeb tsa teeb tsa ntawm lub viav vias kos thawj lub valve tsis txwv. Nws tuaj yeem ntsia rau Pipelines yog ntsia rau ntawm ib qho yeeb nkab ntsug, nruab nrab yuav tsum ntws tawm hauv qab mus rau sab saum toj;
8. Lub viav vias kos duab valve yuav tsum tsis txhob ua rau hauv lub qhov taub me-doo-doo. Nws tuaj yeem ua rau hauv lub siab ua haujlwm siab heev, PN tuaj yeem ncav cuag 42MPA, thiab DN tseem tuaj yeem loj heev, txog li 2000mm. Nyob ntawm cov khoom ntawm lub plhaub thiab lub foob, nws tuaj yeem siv rau cov khoom siv nruab nrab thiab kev ua haujlwm kub. Qhov nruab nrab yog dej, chav dej, roj, nruab nrab, cov roj, tshuaj, thiab lwm yam haujlwm ua haujlwm ntawm {}} degree;
9. Lub sijhawm siv tau muaj peev xwm qis dua siab thiab txoj kab uas hla loj, thiab lub sijhawm ua haujlwm tsawg;
10. Qhov kev teeb tsa txoj hauj lwm ntawm npauj npaim tshawb xyuas valve tsis txwv. Nws tuaj yeem ntsia tau rau ntawm kab rov tav pipeline, lossis ntawm cov raj xa dej ntsug lossis inclinine;
11. Lub diaphragm kos tawm valve yog haum rau pipelines nquag rau dej rauj. Lub diaphragm tuaj yeem tshem tawm cov dej rauj tshwm los ntawm lub nruab nrab nraub qaum. Nws yog feem ntau yog siv rau ntawm cov kav dej qis thiab qhov kub thiab txias tshaj plaws, tshwj xeeb rau cov kais dej. Qhov ntsuas nruab nrab ua haujlwm kub yog nruab nrab ntawm -12--120 degree, thiab cov hauj lwm siab yog<1.6MPa, but the diaphragm check valve can be made of larger diameter, and the maximum DN can be Reach more than 2000mm;
12. Pob dai daim duab yog qhov haum rau nruab nrab thiab cov raj xa hluav taws xob qis thiab tuaj yeem ua rau hauv cov kab zauv loj;
13. Cov plhaub cov khoom ntawm pob kuaj lub valve tuaj yeem ua los ntawm cov hlau uas tsis muaj zog, yog li nws kuj tseem tuaj yeem siv tau hauv cov raj xa khoom ntawm cov xov xwm dav dav. Kev ua haujlwm kub yog nruab nrab ntawm -101--150 degree, nws lub npe nrov yog tsawg dua lossis sib npaug ntawm 200-1200;
14. Thaum xaiv lub xov tooj ntawm lub Voj?
15 Yog tias qhov nruab nrab ntws tau ntau yog loj, ib qho khoom siv deceleration tuaj yeem siv rau lub cim ntsuas pa taws. Yog hais tias cov nruab nrab ntws nres thiab pib sai txuas ntxiv, xws li qhov hluav taws xob ntawm lub compressor, kev nqa lub valve valve yog siv;
16. Tus kos duab valve yuav tsum tau muab me me raws li. Pom cov ntaub ntawv valve yuav tsum muab cov ntaub ntawv raug xaiv kom lub valve loj tuaj yeem pom thaum lub valve tau qhib siab dua ntawm tus nqi ntws.
17. Rau cov siab thiab nruab nrab lub siab xyuas cov khoom hauv qab dn50mm, tuav nqa xyuas cov cuab yeej thiab kev pom zoo nqa cov kev pom zoo;
18. Rau cov khoom siv qis qis qis qis dua DN50mm, Npauj npaim xyuas li qub, ntsug nqa cov roj thiab diaphragm khij cov khoom siv;
19. Rau cov siab thiab nruab nrab lub siab xyuas cov khoom nrog DN ntau dua 50 hli thiab tsawg dua 600mm, viav vias kuaj yuav tsum tau siv;
20. Rau qhov nruab nrab thiab cov khoom lag luam qis dua qub nrog DN ntau dua 200 hli thiab tsawg dua 1200mm, hnav-dawb pob kos duab yuav tsum tau siv;
21. Rau cov khoom lag luam qis nrog DN ntau dua 50 hli thiab tsawg dua 2000mm, Npauj npaim tshawb xyuas li qub thiab Diaphragm xyuas cov khoom siv;
22. Rau cov pipelines uas yuav tsum tau me me lossis tsis muaj dej rauj thaum kaw, qeeb-kaw cov npauj npaim xyuas li qub yuav tsum tau siv.
