Umthethomgomo wokukhetha ivalvu
Ivalvu ekhethiweko kufanele ihlangabezane neenkambisolawulo ezisisekelo ezilandelako.
(1) Ukuphepha nokuthembeka kwe-petrochemical, isiteshi samandla, i-metalurrgy namanye amabubulo kutlhoga ukusebenza okuragela phambili, okuzinzileko, komjikelezo omude. Ngalokho-ke, ivalvu etlhogekako kufanele ibe nokuthembeka okuphezulu, isici esikhulu sokuphepha, ingekhe ibangele ukuphepha okukhulu kokukhiqiza nokulimala kwabantu ngebanga lokuhluleka kwevalvu, ihlangabezane neemfuneko zokusebenza komjikelezo omude wedivayisi, begodu ukukhiqiza okuragela phambili komjikelezo omude kuyinzuzo.
(2) Ukuhlangabezana neemfuneko zokukhiqiza ivalvu kufanele ihlangabezane nokusetjenziswa kwesilinganiso, umfutho wokusebenza, izinga lokutjhisa lokusebenza kanye neemfuneko zokusebenzisa, okubuye kube ziimfuneko ezisisekelo zokukhetha ivalvu. Nangabe kutlhogeka indima yokuvikela ukugandeleleka okukhulu kwevalvu, ukukhupha umkhathi ongaphezu kwalokho, kufanele ukhethe ivalvu yokuphepha, ivalvu yokuphuphuma, kufanele usebenzise ivalvu yokuhlola, kudingeka ukuqeda ngokuzenzakalelayo ipayipi lomtjhiso kanye nemitjhini ye-condensate, umoya neminye igesi engakwazi ukutjhisa, begodu ukukhandela ukuphunyurha komtjhiso, kufanele ukhethe ivalvu yokudonsa. Ukungezelela, lokha umkhakha nawugugako, kufanele kukhethwe izinto ezijamelana nokugqwala ezihle.
(3) Ngemva kokusebenza, ukufakwa, ukuhlola (ukugcinwa) ukulungiswa kwevalvu, umsebenzisi kufanele akghone ukukhomba kuhle umhlahlandlela wevalvu, amatshwayo wokuvula, amatshwayo wokutjengisa, kulula ukutjheja ngesikhathi begodu ngokuqinileko ukulungisa amaphutha ahlukahlukeneko wesikhathi esiphuthumako. Ngesikhathi esifanako, isakhiwo sohlobo lwevalvu esikhethiweko kufanele sibe kude ngendlela okungenzeka ngayo ishidi lesilinda, ukufakwa, ukuhlola (ukugcinwa) ukulungisa okulula.
(4) Umnotho Ngokwesisekelo sokuhlangabezana nokusetjenziswa okujayelekileko kwamapayipi wenqubo, amavalvu aneendleko eziphasi zokukhiqiza nesakhiwo esilula kufanele akhethwe ngendlela ekungakghonakala ngayo ukwehlisa iindleko zedivayisi, ukubalekela ukulahlwa kwezinto ezisetjenziswako zamavalvu begodu ukwehlisa iindleko zokufaka nokugcinwa kwamavalvu esigabeni sokugcina.
Amagadango wokukhetha ivalvu
Ukukhethwa kwamavalvu kuvamise ukulandela amagadango alandelako,
1. Hlola ubujamo bokusebenza kwevalvu ngokuya ngokusetjenziswa kwevalvu kudivayisi nofana iphayiphi yenqubo. Ukwenza isibonelo, isilinganiso sokusebenza, umfutho wokusebenza kanye namazinga womtjhiso wokusebenza, njll.
2. Hlola izinga lokuvala kwevalvu ngokuya ngendlela yokusebenza, indawo yokusebenza kanye neemfuneko zomsebenzisi.
3. Hlola umhlobo wevalvu kanye nendlela yokutjhayela ngokuya ngenjongo yevalvu. Imihlobo efanaIvalvu ye-butterfly eqinileko, Ivalvu yesango elihlezi ngerabha,Ivalvu yesango elihlezi ngerabha, ivalvu yokulinganisa, njll. Indlela yokutjhayela efana ne-worm wheel worm, igezi, i-pneumatic, njll.
4. Khetha ngokuya ngamapharamitha we-valve. Umfutho omncani nobukhulu obuncani bevalvu kufanele bufaniswe nepayipi lendlela efakiweko. Ivalvu ifakwe ngaphakathi kwepayipi yenqubo, ngalokho ubujamo bayo bokusebenza kufanele buhambisane nokukhethwa komklamo wephayiphi yenqubo. Ngemva kokuthi irherho elijwayelekileko kanye nomfutho wepayipi kunqunywe, umfutho wevalvu, ubukhulu obubizwako kanye nokuklanywa kwevalvu namazinga wokukhiqiza kungatholwa. Amanye amavalvu anquma ubukhulu bevalvu ngokuya ngezinga lokugeleza nofana ukuphuma kwevalvu ngesikhathi esilinganisiweko se-medium.
5. Hlola indlela yokuhlanganisa indawo yokuphela kwevalvu nepayipi ngokuya ngobujamo bokusebenza kanye nobukhulu bevalvu. Njenge-flange, ukuwelda, i-wafer nofana intambo, njll.
6. Hlola isakhiwo nefomu lomhlobo wevalvu ngokuya ngendawo yokufaka, isikhala sokufaka, kanye nobukhulu obuncani bevalvu. Njengevalvu yesango elimnyama, isiqu esikhuphukakoivalvu yesango, ivalvu yebholo engatjhugulukiko, njll.
7. Ngokuya ngobujamo bendawo, umfutho wokusebenza kanye namazinga womtjhiso wokusebenza, ukukhetha kuhle nangokuzwakalako ivalvu.
E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyazikhakhazisa ngokunikela ngemikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu webubulo. Ngamavalvu wethu ahlukahlukeneko, ungasithemba bona sizokunikela ngesisombululo esihle khulu sehlelo lakho lamanzi. Sithinta namhlanjesi ukufunda kabanzi ngemikhiqizo yethu nokuthi singakusiza njani.
