Ivalvu yeDiaphragm yenziwe kakhulu ngumzimba wevalvu, isigqubuthelo sevalvu, i-diaphragm, isihlalo sevalvu, isiqu sevalvu kunye nezinye izinto.

3. Umgaqo wokusebenza wevalvu ye-diaphragm

Umgaqo wokusebenza wevalvu yediaphragm ngulo: Umgaqo wokusebenza uxhomekeke kakhulu ekushukumeni kwediaphragm ukulawula ukuhamba kolwelo. Ivalvu yediaphragm ine-diaphragm elastiki kunye nelungu lokucinezela eliqhuba idiaphragm ukuba ihambe. Xa ivalvu ivaliwe, kwakheka isitywina phakathi kwediaphragm kunye nomzimba wevalvu kunye nebhonethi, nto leyo ethintela ulwelo ukuba lungadluli. Xa ivalvu ivuleka, amandla anikwe yindlela yokusebenza abangela ukuba ilungu lokucinezela linyuke, nto leyo ebangela ukuba idiaphragm inyuke emzimbeni wevalvu kwaye ulwelo luqale ukuhamba. Ngokulungisa amandla anikwe yindlela yokusebenza, ukuvulwa kwevalvu kunokulawulwa, ngaloo ndlela kulawula ukuhamba kolwelo.

4. Iingongoma eziphambili zokukhetha iivalvu ze-diaphragm

Khetha izinto ze-diaphragm ezifanelekileyo kunye nezinto zomzimba we-valve ngokweempawu eziphakathi.

Khetha imodeli yevalvu yediaphragm efanelekileyo kunye neenkcukacha ezisekelwe kuxinzelelo olusebenzayo.

Cinga ngendlela esebenza ngayo ivalvu, nokuba yeyombane, yeyomphunga okanye yeyomoya.

Cinga ngemeko yokusebenza kunye neemfuno zobomi benkonzo yevalvu.

5. Iiparameter zokusebenza kwevalvu yeDiaphragm

Iiparameters eziphambili zokusebenza kwevalvu yediaphragm ziquka: uxinzelelo oluqhelekileyo, ububanzi obuqhelekileyo, i-medium efanelekileyo, ubushushu obusebenzayo, imo yokuqhuba, njl. Ezi parameters zifuna ingqalelo ekhethekileyo xa ukhetha kwaye usebenzisa iivalvu zediaphragm.

6. Iimeko zokusetyenziswa kweevalvu zediaphragm

Iivalvu zeDiaphragm zisetyenziswa kakhulu kumashishini okutya, amayeza, ukhuseleko lokusingqongileyo, amachiza kunye namanye amashishini, ingakumbi kwiimeko apho kufuneka kuthintelwe ungcoliseko lwemidiya kwaye zivuleke kwaye zivale ngokukhawuleza, njengokucoca amdaka, ukucutshungulwa kokutya, njl.

7. Ukufakelwa kwevalvu ye-diaphragm

1. Ukulungiselela ngaphambi kokufakwa

Qinisekisa ukuba imodeli kunye neenkcukacha zevalvu ye-diaphragm ziyahambelana neemfuno zoyilo.

Jonga inkangeleko yevalvu yediaphragm ukuqinisekisa ukuba akukho monakalo okanye umhlwa.

Lungisa izixhobo kunye nezinto ezifunekayo zokufakela.

2. Ingcaciso eneenkcukacha zamanyathelo okufakela

Ngokwendlela yokubeka umbhobho, misela indawo yokufakela kunye necala levalvu yediaphragm.

Faka ivalvu yediaphragm kumbhobho, uqinisekise ukuba umzimba wevalvu uhambelana nomphezulu weflange yombhobho kwaye ungena kakuhle.

Sebenzisa iibholithi ukubopha umzimba wevalvu kwiflange yombhobho ukuqinisekisa uqhagamshelo olukhuselekileyo.

Jonga imeko yokuvulwa nokuvalwa kwevalvu yediaphragm ukuqinisekisa ukuba idiaphragm iyakwazi ukuhamba ngokukhululekileyo kwaye akukho kuvuza.

3. Amanyathelo okufaka

Kuphephe ukonakalisa i-diaphragm ngexesha lokufakwa.

Qinisekisa ukuba indlela yokusebenza yevalvu yediaphragm ihambelana nendlela yokusebenza.

Qinisekisa ukuba ivalvu ye-diaphragm ifakwe kwicala elifanelekileyo ukuze ingaphazamisi ukusebenza kwayo okuqhelekileyo.

4. Iingxaki zokufakelwa eziqhelekileyo kunye nezisombululo

Ingxaki: Ivalvu yeDiaphragm iyavuza emva kokufakelwa. Isisombululo: Jonga ukuba uqhagamshelo luqinile na, kwaye uluqinise kwakhona ukuba alukhululekanga; jonga ukuba idiaphragm yonakele na, uze uyitshintshe ukuba kunjalo.

Ingxaki: Ivalvu yediaphragm ayiguquguquki xa ivula kwaye ivala. Isisombululo: Jonga ukuba indlela yokusebenza iyaguquguquka na, kwaye uyicoce ukuba kukho ukuxinana; jonga ukuba idiaphragm iqine kakhulu na, kwaye uyilungise ukuba kunjalo.

5. Ukuhlolwa novavanyo emva kokufakwa

Jonga inkangeleko yevalvu yediaphragm ukuqinisekisa ukuba akukho monakalo okanye ukuvuza.

Sebenzisa ivalvu yediaphragm kwaye ujonge imeko yayo yokuvula nokuvala ukuqinisekisa ukuba iguquguquka kwaye ayinaziphazamiso.

Yenza uvavanyo lokuqina ukuqinisekisa ukuba ivalvu ye-diaphragm ayivuzi xa ivaliwe.

Ngamanyathelo angentla kunye nokhuseleko, ungaqinisekisa ukufakwa ngokuchanekileyo kunye nokusebenza okuqhelekileyo kwevalvu ye-diaphragm ukuze kuhlangatyezwane neemfuno zokusetyenziswa.
