Izikhokelo zokuKhetha iValve kunye noTshintsho lweZenzo eziLungileyo

Ukubaluleka kokukhethwa kwevalvu: Ukukhethwa kwezakhiwo zevalvu yokulawula kumiselwa ngokuqwalasela ngokubanzi imiba efana nephakathi esetyenzisiweyo, ubushushu, uxinzelelo olusuka phezulu kunye nolusezantsi lomsinga, izinga lokuhamba, iipropati ezibonakalayo kunye neekhemikhali zesiphakathi, kunye nokucoceka kwesiphakathi. Ukuchaneka kunye nengqiqo yokukhethwa kwesakhiwo se-valve kukuchaphazela ngokuthe ngqo ukusebenza, amandla okulawula, ukuzinza kommiselo, kunye nobomi benkonzo.

I. Inkqubo yeeParamitha:

1. Phakathi'sIgama.
2. Uxinaniso oluphakathi, i-viscosity, ubushushu, kunye nokucoceka kwendawo ephakathi (kunye ne-particulate matter).
3. IiPropati zePhysicochemical eziPhakathi: Ukonakala, ubutyhefu, kunye ne-pH.
4. Amaxabiso okuHamba okuPhakathi: Elona nani liphezulu, liQhelekileyo, kunye nelona lincinane
5. Uxinzelelo oluPhezulu kunye nezantsi kweValve: Ubuninzi, obuqhelekileyo, ubuncinci.
6. I-viscosity ephakathi: ukuphakama kwe-viscosity, ngakumbi kuchaphazela ukubalwa kwexabiso leCv.

Ezi parameters zisetyenziselwa ukubala i-diameter ye-valve efunekayo, ixabiso le-Cv elilinganisiweyo, kunye nezinye iiparamitha ezinobungakanani, kunye nokugqiba izinto ezifanelekileyo ezifanele ukusetyenziswa kwivalve.

II. Iiparamitha ezisebenzayo:

1. Iindlela zokusebenza: umbane, umoya,unyulo-hydraulic, hydraulic.
2. Ivalve'simisebenzi: ummiselo, ukuvala, kunye nommiselo odibeneyo&cime ngaphandle.
3. Iindlela zokulawula:Umfaki-sicelo, ivalve ye-solenoid, ivalve yokunciphisa uxinzelelo.
4. Ixesha elifunekayo lesenzo.

Le nxalenye yeeparameters isetyenziselwa ikakhulu ukumisela ezinye izixhobo ezincedisayo ezifuna ukulungiswa ukuhlangabezana neemfuno zokusebenza zevalve.

III. Iiparamitha zokukhusela uqhushumbo:

1. Uqikelelo lobungqina bokudubula.
2. Inqanaba lokhuseleko.

IV. Uluhlu lweeParamitha zeNdalo kunye neDynamic

1. Ubushushu obugciniwe.
2. Iiparamitha zamandla: uxinzelelo lokubonelela ngomoya, uxinzelelo lombane.

ImiGaqo yokuTshintsha iivalvu

Ukuqinisekisa ukutshintshwa kwevalvu ehambelanayo kunye nokuthintela imiba yofakelo, nceda unikeze le milinganiselo ilandelayo. Ukwahluka phakathi kwabavelisi kunye noyilo kunokukhokelela kwindawo engafanelekanga okanye engonelanga. NgeTWS, iingcali zethu ziya kulungelelanisa isisombululo ngokucebisa ivalve efanelekileyo—ivelufa butterfly, ivalve yesango, okanyekhangela ivalve-kwiimfuno zakho, ukuqinisekisa ukusebenza kunye nokuqina.
