Iimpawu zeValve 101: Ukuqonda Iintlobo eziphambili, iMigangatho, kunye nezicelo kwiMifanekiso yeP&ID

Zithini Iimpawu zeValve

Iimpawu zevalvu ziimpawu zemizobo ezisemgangathweni ezisetyenziswa kwiImizobo yeMibhobho kunye neZixhobo (P&ID)ukubonisa uhlobo, umsebenzi, kunye nokusebenza kweevalvu kwinkqubo. Ezi mpawu zibonelela "ngolwimi" oluqhelekileyo kwiinjineli, abayili, kunye neengcali ukuze banxibelelane neenkqubo zemibhobho ezintsonkothileyo ngokufanelekileyo.

Kutheni Iimpawu zeValve zibalulekile

1. Ukucaca kuYilo: Susa ukungacaci kwimizobo yobugcisa.

2. Ukubekwa eMgangathweni kweHlabathi: Landela imigangatho ye-ISO, i-ANSI, okanye ye-ISA ukuze ufumane ukuhambelana.

3. Ukhuseleko kunye nokusebenza kakuhle: Qinisekisa ukuba ukukhethwa kweevalvu ngokufanelekileyo kunye nokusebenza kwenkqubo.

4. Ukulungisa ingxaki: Yenza lula ukugcinwa kunye nokulungiswa kokusebenza.

Iimpawu zeValve eziqhelekileyo zichaziwe

1. Uphawu lweValve yeBhola

– Isangqa esinomgca othe nkqo embindini waso.

– Imele amandla okucima ngokukhawuleza; ixhaphakile kwiinkqubo zeoyile, igesi, kunye namanzi.

2. Uphawu lweValve yeSango

– Unxantathu ojonge phezulu/ezantsi phakathi kwemigca emibini ethe tye.

– Ibonisa ulawulo lwentshukumo oluthe tye lokuhamba ngokupheleleyo okanye ukwahlukana.

3. Jonga uphawu lweValve

– Utolo oluncinci ngaphakathi kwesangqa okanye imilo "ye-clapper".

– Iqinisekisa ukuhamba kweendlela eziya kwicala elinye; ithintela ukubuya kweendlela kwiipayipi.

4. Uphawu lweValve yeBhabhathane

– Imigca emibini ethe tyaba edibanayo nesangqa.

– Isetyenziselwa ukuqhobosha; ixhaphakile kwiinkqubo ezinobukhulu obukhulu nezinoxinzelelo oluphantsi.

5. Uphawu lweValve yeGlobe

– Imo yedayimani ngaphakathi kwesangqa.

– Yenzelwe ukulawula ukuhamba kwamanzi ngokuchanekileyo kwiindawo ezisebenzisa uxinzelelo oluphezulu.

Imigangatho ephambili yeempawu zeValve

- I-ISO 14691: Ichaza iisimboli zevalvu eziqhelekileyo kwiinkqubo zoshishino.

- I-ANSI/ISA 5.1: Iimpawu ze-P&ID zikaRhulumente eMelika

- I-DIN 2429: Umgangatho waseYurophu wemizobo yobugcisa.

Iingcebiso zokufunda iimpawu zevalvu

- Soloko ubhekisa kwintsomi ye-P&ID ukuze ufumane iinguqulelo ezithile zeprojekthi.

- Qaphela iintlobo ze-actuator (umz., ngesandla, ngomoya, ngombane) ezidityaniswe neempawu.

Ukuqondaiisimboli zevalvuKubalulekile kuyilo lwenkqubo oluchanekileyo, ukuthobela ukhuseleko, kunye nentsebenziswano engenamthungo phakathi kwamaqela obunjineli.ivalvu yebholaumsebenzi wokuvala okanyeivalvu yeglobhuindima yokuqhobosha, ukuzilawula ezi zintoiisimbolikuqinisekisa ukuphunyezwa kweprojekthi ngokufanelekileyo.
