Dab tsi yog lub luag haujlwm ntawm hluav taws xob valve positioner?

Dab tsi yog lub luag haujlwm ntawm hluav taws xob valve positioner? Hauv qab no yog ib qho kev qhia rau koj.

Cov hauj lwm piav qhia ntawm hluav taws xob valve positioner yog raws li nram no:

1. Hluav taws xob valve positioner yog ib tug regulating system uas yuav tsum tau siab rau regulating zoo, uas yuav tsum tau los txhim kho lub positioning degree thiab kev cia siab ntawm lub regulating valve.

2. Nws yog ntsia qhov twg lub siab sib txawv ntawm ob qhov kawg ntawm lub valve yog siab dua 1MPa. Ua kom lub zog tso tawm ntawm lub oob khab los ntawm kev ua kom huab cua siab, kov yeej lub zog sib txawv ntawm cov kua dej ntawm lub valve core, thiab txo qhov yuam kev hauv cov hlab ntsha.

3. Txhawm rau kom tsis txhob cuam tshuam sab nraud, thaum cov dej ntws muaj qhov kub thiab txias, siab kub, tsis tshua muaj kub, tshuaj lom, flammable, tawg thiab lwm lub xeev, cov muab tub lim feem ntau yuav nyem nruj heev, thiab kev sib txhuam ntawm lub valve pas nrig thiab cov filler yuav nce. Lub sijhawm no, hluav taws xob valve positioner tuaj yeem kov yeej lub sijhawm lag luam.

4. Thaum cov kua dej khov los yog muaj cov khoom uas raug tshem tawm, kev siv hluav taws xob valve positioners tuaj yeem txo qhov tsis kam ntawm cov kua rau kev txav ntawm lub valve qia.

5. Lub tshuab hluav taws xob valve positioner tseem tuaj yeem kov yeej kev sib kis lag luam ntawm cov teeb liab tswj thiab txhim kho qhov kev txiav txim siab ceev ntawm lub valve.

6. Txhim kho cov yam ntxwv ntws ntawm cov tswj valve.

7. Thaum ib tug regulator tswj ob actuators, ob tug hluav taws xob valve positioners yuav siv tau, nrog rau ib tug tsawg ntau yam kev txiav txim thiab lwm yam nce siab. Txais cov teeb liab input tsawg thiab siab input teeb liab feem kom ua tiav cov kev cai sib cais.
