Pob valvenyob rau hauv cov kav dej yog tsuas yog siv los txiav tawm, faib thiab hloov qhov ntws ntawm qhov nruab nrab.Pob valve yog hom tshiab ntawm lub valve uas tau siv dav hauv xyoo tas los no.Nws muaj qhov zoo hauv qab no:

1. Cov dej tsis kam yog me me, thiab nws cov coefficient kuj yog sib npaug ntawm cov yeeb nkab ntu ntawm tib qhov ntev.

2. Cov qauv yooj yim, ntim me me, lub teeb yuag.

3. Tight thiab txhim khu kev qha, sealing nto khoom ntawm lub pob valve yog dav siv yas, zoo sealing, thiab tau dav siv hauv lub tshuab nqus tsev.

4. Yooj yim rau kev khiav lag luam, qhib thiab kaw sai, los ntawm kev qhib tag nrho mus rau tag nrho kaw ntev npaum li qhov kev sib hloov ntawm 90 °, yooj yim rau kev tswj chaw taws teeb.

5. Kev saib xyuas yooj yim, pob valve qauv yog yooj yim, lub nplhaib sealing feem ntau ua haujlwm, disassembly thiab hloov tau yooj yim dua.

6. Thaum qhib tag nrho lossis kaw tag nrho, lub sealing nto ntawm lub pob thiab lub rooj zaum valve raug cais tawm ntawm qhov nruab nrab.Thaum qhov nruab nrab dhau mus, nws yuav tsis ua rau yaig ntawm lub valve sealing nto.

7. Muaj feem xyuam rau ntau qhov ntau thiab tsawg los ntawm me me mus rau ob peb millimeters mus rau ob peb meters, los ntawm lub tshuab nqus tsev mus rau siab siab tuaj yeem siv tau.

Pob valvetau siv dav hauv roj av, tshuaj lom neeg kev lag luam, hluav taws xob tsim, papermaking, atomic zog, aviation, foob pob hluav taws thiab lwm yam haujlwm, nrog rau tib neeg lub neej txhua hnub.
