Qwalasela indawo yokusebenza kunye neemfuno zobomi benkonzo yesivalo.

5. Iiparamitha zevalvu ye-diaphragm

Iiparamitha eziphambili zentsebenzo yevalve ye-diaphragm ziquka: uxinzelelo lwegama, i-diaphragm yegama, i-medium esebenzayo, iqondo lokushisa elisebenzayo, imodi yokuqhuba, njl. Ezi parameters zifuna ingqalelo ekhethekileyo xa ukhetha kwaye usebenzisa i-diaphragm valves.

6. Iimeko zokusetyenziswa kweevalvu ze-diaphragm

Iivalve ze-diaphragm zisetyenziswa ngokubanzi kukutya, amayeza, ukukhuselwa kwendalo, iikhemikhali kunye namanye amashishini, ngakumbi kwiimeko apho kuyimfuneko ukukhusela ukungcoliswa kweendaba kunye nokuvula nokuvala ngokukhawuleza, njengokunyangwa kwamanzi amdaka, ukulungiswa kokutya, njl.

7. Ukufakwa kwevalve ye-diaphragm

1. Ukulungiswa phambi kofakelo

Qinisekisa ukuba imodeli kunye neenkcukacha zevalve ye-diaphragm zihambelana neemfuno zoyilo.

Khangela inkangeleko yevalve ye-diaphragm ukuqinisekisa ukuba akukho monakalo okanye umhlwa.

Lungiselela izixhobo eziyimfuneko zokufakela kunye nezixhobo.

2. Inkcazo eneenkcukacha yamanyathelo ofakelo

Ngokutsho koyilo lwemibhobho, misela indawo yofakelo kunye nesalathiso sevalve ye-diaphragm.

Fakela ivalve ye-diaphragm kumbhobho, uqinisekise ukuba umzimba wevalve uhambelana nomphezulu weflange wombhobho kwaye ungena ngokuqinileyo.

Sebenzisa iibholithi ukuqinisa umzimba wevalve kwiflange yombhobho ukuqinisekisa uqhagamshelo olukhuselekileyo.

Khangela indawo yokuvula kunye nokuvala i-valve ye-diaphragm ukuqinisekisa ukuba i-diaphragm inokuhamba ngokukhululekile kwaye akukho kuvuza.

3. Amanyathelo okhuseleko ofakelo

Kuphephe ukonakalisa i-diaphragm ngexesha lofakelo.

Qinisekisa ukuba indlela yokusebenza yevalve yediaphragm ihambelana nendlela yokusebenza.

Qinisekisa ukuba i-valve ye-diaphragm ifakwe kwicala elichanekileyo ukuze ugweme ukuchaphazela ukusebenza kwayo okuqhelekileyo.

4. Iingxaki zokufakela eziqhelekileyo kunye nezisombululo

Ingxaki: Ivalve ye-diaphragm iyavuza emva kokufakwa. Isisombululo: Jonga ukuba unxibelelwano luqinile, kwaye uluqinise kwakhona ukuba lukhululekile; khangela ukuba i-diaphragm yonakele, kwaye uyibuyisele ukuba kunjalo.

Ingxaki: Ivalve ye-diaphragm ayiguquki ekuvuleni nasekuvaleni. Isisombululo: Jonga ukuba indlela yokusebenza iyaguquguquka, kwaye uyicoce ukuba kukho ukuxinana; khangela ukuba i-diaphragm iqinile kakhulu, kwaye uyilungise ukuba kunjalo.

5. Ukuhlolwa nokuhlolwa kwasemva kokufakwa

Khangela inkangeleko yevalve ye-diaphragm ukuqinisekisa ukuba akukho monakalo okanye ukuvuza.

Sebenzisa ivalve ye-diaphragm kwaye ujonge isimo sayo sokuvula kunye nokuvala ukuqinisekisa ukuba iyaguquguquka kwaye ayinamqobo.

Yenza uvavanyo lokuqina ukuqinisekisa ukuba ivalve ye-diaphragm ayivuzi xa ikwimeko evaliweyo.

Ngokusebenzisa la manyathelo angentla kunye nezilumkiso, unokuqinisekisa ukufakela okuchanekileyo kunye nokusebenza okuqhelekileyo kwevalve ye-diaphragm ukuhlangabezana neemfuno zokusetyenziswa.
