Pipeline Valve Installation Regulations and Installation Requirements

1. Thaum txhim kho lub solenoid valve, xyuam xim rau cov kev taw qhia ntawm qhov nruab nrab ntws yuav tsum ua raws li cov kev taw qhia ntawm xub cim rau ntawm lub valve lub cev.

2. Cov twj tso kua mis yuav tsum tau muab ntsia rau ntawm qhov nkag sab ntawm lub solenoid valve. Lub ntxiab yuav tsum tau muab ntsia rau ntawm qhov chaw qis tshaj ntawm cov khoom siv hluav taws xob kom tso tawm cov condensate nyob rau lub sijhawm kom tsis txhob muaj qhov thaiv.

3. Yog hais tias muaj cov condensate rov qab tom qab lub ntxiab, lub ntxiab qhov hluav taws xob yeeb nkab yuav tsum tau txuas nrog lub manifold los ntawm sab saum toj ntawm qhov rov qab manifold kom txo qis rov qab siab thiab tiv thaiv rov qab.

4. Lub qia valve tsis tuaj yeem muab faus los tiv thaiv lub qia los ntawm xeb. Nyob rau hauv lub trench nrog lub hau, lub valve yuav tsum tau ntsia rau ntawm qhov chaw ntawm kev saib xyuas thiab kev soj ntsuam thiab kev ua haujlwm.

5. Thaum txhim kho lub threaded valve, nws yog ib qho tsim nyog los xyuas kom meej tias cov xov tsis zoo, thiab cov khoom sib khi yog coated raws li cov xov xwm sib txawv. Thaum nruj, nws yog ib qho tsim nyog yuav tsum tau siv txawm tias quab yuam kom tsis txhob muaj kev puas tsuaj rau lub valve thiab valve fittings.

6. Thaum lub qhov (socket type welding valve) tau teeb tsa, lub qhov (socket) yuav tsum muaj qhov sib txawv ntawm 1-2m los tiv thaiv qhov vuam ntawm qhov sib tsoo thaum lub thermal stress loj dhau thaum vuam.

7. Solenoid li qub yog qhov zoo tshaj plaws ntsia kab rov tav, nrog cov coils tig mus rau sab saud lossis nrog txoj kab nqes qis dua 45 degrees.

8. Docking valve thiab yeeb nkab txuas Weld hauv qab txheej yuav tsum tau welded los ntawm argon arc vuam. Thaum vuam, lub valve yuav tsum qhib kom tsis txhob overheating deformation.

9. Ib txwm ntxuav cov yeeb nkab nrog cov pa roj ua ntej txhim kho lub solenoid valve kom tshem tawm cov khib nyiab ntawm cov yeeb nkab.

10. Nruab ib lub lim rau pem hauv ntej ntawm lub solenoid valve kom paub meej tias lub solenoid valve tsis thaiv los ntawm cov kav dej khib nyiab thiab ntxuav lub lim tsis tu ncua.

11. Valves uas flanged thiab threaded yuav tsum raug kaw thaum lub sij hawm installation.

12. Thaum txhim kho flanged li qub, xyuas kom meej tias lub ntsej muag kawg ntawm ob lub flanges yog tib yam thiab concentric rau ib leeg.

13. Tsis txhob tso cai rau lub solenoid valve los nqa qhov hnyav hauv cov kav dej. Loj solenoid li qub yuav tsum tau txais kev txhawb nqa ntawm nws tus kheej kom tsis txhob cuam tshuam los ntawm lub siab tsim los ntawm cov kav dej.
