Indawo ezimbini ezinendlela yeplagi-in yokulawula i-clutch valve SV10-40

Uhlobo

Kukho iintlobo ezininzi zemizimba yevalvu yeevalvu zokulawula, ezifana nesihlalo esithe ngqo, isihlalo esithe tye, i-angular, i-diaphragm, ukuhamba okuncinci, iindlela ezintathu, ukujikeleza kwe-eccentric, ibhabhathane, i-sleeve kunye ne-spherical. Kukhetho olukhethekileyo, oku kuqwalaselwa kulandelayo kunokwenziwa:

1. Ikakhulu iqwalaselwa ngokwemiba ekhethiweyo efana neempawu zokuhamba kunye namandla angalinganiyo.

2. Xa i-fluid medium is suspension equkethe i-concentration ephezulu ye-particle abrasive, izinto zangaphakathi zevalve kufuneka zibe nzima.

3. Ngenxa yokuba i-medium is corrosive, zama ukukhetha ivalve enesakhiwo esilula.

4. Xa iqondo lokushisa kunye noxinzelelo lwe-medium liphezulu kwaye litshintshile kakhulu, i-valve enezinto zayo ze-valve core kunye nesihlalo se-valve asichatshazelwa kangako ngubushushu kunye noxinzelelo kufuneka kukhethwe.

5. I-Flash evaporation kunye ne-cavitation yenzeke kuphela kwimidiya engamanzi. Kwinkqubo yangempela yokuvelisa, i-flash evaporation kunye ne-cavitation iya kubangela ukungcangcazela kunye nengxolo, eya kunciphisa ubomi benkonzo yevalve. Ngoko ke, i-flash evaporation kunye ne-cavitation kufuneka ithintelwe xa ukhetha i-valve.

Uphawu

1. Kukho iintlobo ezahlukeneyo zeevalvu zokulawula, kwaye amaxesha azo asebenzayo ahlukile. Ngoko ke, uhlobo lwevalve yokulawula kufuneka lukhethwe ngokufanelekileyo ngokweemfuno zenkqubo yokuvelisa.

2. Iivalve zokulawula umoya zihlukaniswe ngamacandelo amabini: ukuvulwa komoya kunye nokuvalwa komoya. I-valve yokulawula yokuvula umoya ivaliwe kwisimo esiphosakeleyo, kwaye i-valve yokulawula ukuvala umoya ivuliwe kwimeko yephutha. Ezinye izixhobo ezincedisayo zingasetyenziselwa ukwenza ivalve yokugcina okanye ukwenza ivalve yokulawula izitshixe, oko kukuthi, ivalve yokulawula igcina ivalve ivula phambi kokusilela xa isilela.

3. Indlela yokuvula umoya kunye nokuvalwa komoya inokuqondwa ngeentlobo ze-activators ezintle kunye nezibi kunye nokudibanisa kwee-valve ezintle kunye nezibi. Xa usebenzisa ivalve positioner, inokubonwa nasisibekeli ivelufa.

4. Iivalve zokulawula ezahlukeneyo zinezakhiwo kunye neempawu ezahlukeneyo.
