Lub tshuab hluav taws xob kaw hluav taws xob feem ntau yog siv rau kev txiav tawm, faib thiab hloov cov kev taw qhia ntws ntawm qhov nruab nrab hauv cov raj xa dej. Hluav taws xob kaw-kaw valve yog hom tshiab ntawm lub pob valve uas tau siv dav. Nws muaj cov kev zoo hauv qab no:
1. Cov dej tsis kam ua kua yog qhov me me, thiab nws cov kuj tiv thaiv tau yog sib npaug ntawm ib ntu ntawm cov yeeb nkab ntawm tib ntev.
2. Cov qauv yooj yim, loj me thiab lub teeb yuag.
3. Nws yog nruj thiab txhim khu kev qha, thiab cov txheej txheem sealing saum npoo ntawm lub rooj vag valve yog dav siv hauv plastics, nrog kev ua tau zoo sealing, thiab tau siv dav hauv cov tshuab nqus tsev.
4. Nws yog qhov yooj yim rau kev khiav lag luam thiab qhib thiab kaw nrawm. Nws tsuas yog yuav tsum tig 90 ° los ntawm kev qhib siab kom puv kaw, uas yooj yim rau kev tswj chaw taws teeb.
5. Kev saib xyuas yog yooj yim, lub rooj vag valve muaj cov qauv yooj yim, lub nplhaib sib khi feem ntau txav tau, thiab nws yooj yim rau disassemble thiab hloov.
6. Thaum qhib tag nrho lossis kaw tag nrho, qhov chaw sib khi ntawm lub rooj vag lub cev thiab lub rooj sib tw lub valve tau cais tawm ntawm qhov nruab nrab, thiab qhov nruab nrab yuav tsis ua rau muaj kev yaig ntawm lub valve sealing nto thaum nruab nrab. 7. Nws muaj ntau hom ntawm kev siv, nrog rau txoj kab uas hla ntawm ob peb millimeters mus rau ob peb metres, thiab tuaj yeem siv los ntawm lub tshuab nqus tsev siab mus rau kev siab siab. Thaum lub pob tig 90 degrees, nws yuav tsum qhia lub npoo ntawm qhov chaw nkag thiab tawm, yog li txiav txiav tawm mus.
Lus khaws xav
1. Ua zoo rau cov kev taw qhia ntws ntawm qhov nruab nrab thaum txhim kho lub valve, thiab nruab nws nruj me ntsis rau hauv cov kev taw qhia qhia los ntawm lub ntsuas phom txaus qhia.
2. Lub tshuab muaj peev xwm muab ntsia tau rau txhua qhov chaw ntawm lub raj xa dej, thiab tib lub sijhawm, xaiv lub valve ntawm carbon steel lossis alloy steel raws li qhov kub ntawm qhov nruab nrab thiab nruab nrab.
3. Lub tshuab hluav taws xob nres valve yuav tsum muab ntsia rau qhov sib txawv kom deb li deb tau, nrog cov qia mus rau sab saud.
