Iintlobo kunye nokukhethwa kwezinto zokuncedisa ivalvu yomoya

Kwinkqubo yokusebenzisaIvalvu yomoya, kudla ngokuba yimfuneko ukumisela ezinye izinto ezincedisayo ukuphucula ukusebenza kwevalvu yomoya, okanye ukuphucula ukusebenza kakuhle kokusetyenziswa kwevalvu yomoya. Izixhobo eziqhelekileyo zeevalvu zomoya ziquka: izihluzi zomoya, iivalvu zesolenoid ezibuyisela umva, iiswitshi zomda, ii-positioners zombane, njl. Kwitekhnoloji yomoya, izinto ezintathu zokucubungula umthombo womoya zesihluzi somoya, ivalvu yokunciphisa uxinzelelo kunye ne-oyile mister zihlanganiswa kunye, ebizwa ngokuba yi-pneumatic triple piece. Isetyenziselwa ukungena kumthombo womoya ukucoca nokucoca isixhobo somoya kunye nokunciphisa uxinzelelo kwisixhobo ukubonelela umthombo womoya olinganisiweyo. Uxinzelelo lulingana nomsebenzi we-transformer yamandla kwisekethe.

Iintlobo zezixhobo zeVluve yePneumatic:

I-Actuator ye-Pneumatic esebenza kabini:

Ulawulo oluneendawo ezimbini zokuvula nokuvala ivalvu. (Isebenza kabini)

I-actuator ye-Pneumatic yokubuya kwentwasahlobo:

Ivalvu ivula okanye ivala ngokuzenzekelayo xa isekethe yegesi yesekethe inqunyulwe okanye ingasebenzi kakuhle. (Isebenza kanye)

Ivalvu yesolenoid enye elawulwa ngombane:

Ivalvu iyavula okanye ivale xa umbane unikezelwa, kwaye iyayivala okanye iyivule xa umbane ulahlekile (zikhona iinguqulelo ezingenakuqhushumba).

Ivalvu yesolenoid elawulwa ngombane kabini:

Ivalvu iyavuleka xa enye ikhoyili inikwe amandla, kwaye ivalvu iyavala xa enye ikhoyili inikwe amandla. Inomsebenzi wememori (uhlobo olungenabungqina luyafumaneka).

Ibhokisi yokutshintsha umda:

Ukudluliselwa komgama omde kwesignali yokutshintsha indawo yevalvu (enohlobo olungenakuqhuma).

Isibekeli soMbane:

Lungisa kwaye ulawule ukuhamba okuphakathi kwevalvu ngokobungakanani besignali yangoku (eqhelekileyo eyi-4-20mA) (enohlobo olungenakuqhuma).

Indawo yokuma yomoya:

Lungisa kwaye ulawule ukuhamba okuphakathi kwevalvu ngokobungakanani besignali yoxinzelelo lomoya (umgangatho we-0.02-0.1MPa).

Isiguquli sombane:

Iguqula isignali yangoku ibe sisignali yoxinzelelo lomoya. Isetyenziswa kunye ne-pneumatic positioner (enohlobo olungenakuqhuma).

I-FRL (Isihluzi somoya, iValvu yoLawulo, iLubricator):

Isihluzi soMoya (F): isetyenziselwa ukucoca ukungcola kunye nokufuma emoyeni ocinezelweyo ukuqinisekisa ukucoceka kwenkqubo yomoya.

Ivalvu yoLawulo (R): isetyenziselwa ukunciphisa igesi enoxinzelelo oluphezulu ukuya kuxinzelelo olufunekayo ukuqinisekisa ukusebenza okuqhelekileyo kwezixhobo zomoya.

‌I-lubricator (L): isetyenziselwa ukufaka isixa esifanelekileyo seoyile yokuthambisa kwinkqubo ye-pneumatic ukunciphisa ukungqubana nokwandisa ubomi bezixhobo.

Ezi zixhobo zihlala zisetyenziswa kunye, ezibizwa ngokuba yi-pneumatic triplex (FRL), edlala indima yokucoca, ukuhluza kunye nokunciphisa uxinzelelo kwitekhnoloji ye-pneumatic.

Indlela Yokusebenza Ngesandla:

Ulawulo oluzenzekelayo lungasetyenziswa ngesandla phantsi kweemeko ezingaqhelekanga.

Ukukhethwa kwezixhobo zeVluve yePneumatic

I-Pneumatic Valve sisixhobo sokulawula esizenzekelayo esintsonkothileyo. Yenziwe ngezinto ezahlukeneyo zomoya. Abasebenzisi kufuneka benze ukhetho oluneenkcukacha ngokweemfuno zolawulo.
