I-Hydraulic threaded cartridge valve control RV10/12-22AB

Okokuqala, izizathu zokungaphumeleli kokulawulwa koxinzelelo lwevalve yokunceda

1. Amandla okuqinisa kwangaphambili entwasahlobo awakafikeleli kumsebenzi wokulungelelanisa, okwenza ukuba intwasahlobo ilahlekelwe yi-elasticity yayo.

2. Ikhoyili kwi-different pressure relay iyatshiswa okanye inoqhagamshelwano olubi.

3. I-pointer ye-pressure gauge iyaphambuka, ibangele uxinzelelo olungachanekanga.

I-4, uxinzelelo lokulawula i-valve spring deformation okanye i-fracture kunye nezinye iimpazamo.

Okwesibini, isisombululo sokungaphumeleli kokulawula uxinzelelo lwevalve

1. Amandla okuqinisa kwangaphambili entwasahlobo kufuneka alungiswe xa ulawula uxinzelelo. Ngokwemeko yangempela, i-handwheel inokuguqulwa ukuya ekupheleni xa intwasahlobo ixinzelelwe ubuncinane kwi-10-15 mm. Ukuba uxinzelelo luyenyuka, amandla okuqinisa kwangaphambili ancinci kakhulu, kwaye kufuneka ahlaziywe kwakhona.

2. Ukuba uxinzelelo aluhambelani neemfuno ezilinganisiweyo, i-valve yokunceda i-overflow inokuthi ilungiswe ide ifikelele kwixabiso elichaziweyo. Okwesithathu kukulungelelanisa i-deformation okanye ukuphuka kwentwasahlobo, ngoko inokulungiswa kuphela ngokutshintsha intwasahlobo entsha.

Ukungaphumeleli kokulawulwa kwevalve yokunceda kuya kuba nempembelelo enkulu, ngakumbi xa isixhobo sikwimeko ephezulu yomthwalo. Xa ivalve yokukhulula ifunyaniswa ingasebenzi kakuhle, inyathelo lokuqala eliza kuthathwa kukuthoba uxinzelelo uze uyilungise kwakhona, ukuze ikwazi ukuphinda iqalise umsebenzi wesiqhelo emva kwamaxesha aliqela.

1. Jonga ukuba isixhobo se-throttle siyavuza i-oyile: ukuba kukho ukuvuza, kusenokwenzeka ukuba iringi yokutywina phakathi kwe-valve core kunye nesihlalo sevalve yevalve ye-throttle yonakele, okukhokelela ekutywinweni kakubi.

2. Qwalasela ukungcola kumphezulu wokutywina we-throttle: Ukuba ubumdaka bugxumeke entlakohlaza okanye yenze ukuba undoqo wevalve ubethe umphezulu wokutywina wesihlalo sevalvu ngexesha lokutshova, oko kuya kubangela ukusilela kokuthontsiza.

3. Hlola ubuninzi bomphezulu we-throttle: Xa ubuninzi be-throttle bungahambelani neemfuno eziqhelekileyo, kulula ukunciphisa indawo enqamlezileyo yomgudu, ukunciphisa izinga lokuhamba kwaye kubangele ukuvala.

4. Xa i-valve yendlela enye ihluleka ukulungisa ukuhamba, iqhekeza le-throttle kufuneka libe phantsi kuqala.

5. Khangela ukuba indawo yofakelo yevalve yendlela enye ichanekile. Ukuba ayichanekanga, phinda ubale imeko yokusebenza kwe-hydraulic kwaye unqume i-coefficient yokumelana nokuhamba. Emva kokubala kwakhona imeko yokusebenza kwe-hydraulic kunye ne-hydraulic balance, misela inqanaba loxinzelelo lwayo ngokweziphumo zokubala kwaye ukhethe imodeli efanelekileyo yevalve ye-throttle.
