I-Flanged Gate Valve: Iintlobo kunye neendlela

I-valve yesango edibeneyo ifakwe kwiipayipi ukuqinisekisa ukuba ukunikezelwa kwamanzi okukhawulezileyo kungavalwa ngokukhawuleza kwaye emva koko kuphelelwe umda. Ukwandisa izinga lokhuseleko, ezi zinto zifumaneka kuwo onke amanqanaba enethiwekhi.

Inkcazelo

Isango le-Flanged lisebenza njengesigxina sokumisa kunye nesakhiwo esilula, naphezu kobuchule obuphezulu. Ikwahlulo lwamachule e-domestic shutter kwaye ine-special block block in the middle of the structure, ukusebenza kwayo kuxhomekeke kuhlobo lwe-valve ngokwayo. Eyona ndawo iqhelekileyo yayiyi-disc stop, idibanisa i-wedge nebhola ejikelezayo.

I-valve yesango i-Flanged inegama layo ngenxa yamacenge ekhethekileyo e-flange, ekhoyo kwimida. Zisetyenziselwa ukubonelela ngokukhawuleza kwinkqubo kunye nokukhutshwa kwefowuni yomsebenzi wokubuyisela okanye wokulungisa. Kufuneka kuqatshelwe ukuba ubukhulu bento yeflethi ehambelana nayo kufuneka ihambelane nomgca omkhulu. Ngaphandle koko, uxhumano aluyi kuba nomgangatho ofanelekileyo, okanye aluyi kwenzeka.

Iingenelelo kunye nokungalunganga

Phakathi kwezinto ezintle eziphambili, kuyafaneleka ukuphawula oku kulandelayo:

• Ukuqinisekisa ukuba kungenzeka ukulungiswa ngokukhawuleza okanye ukutshintshwa kweso sixhobo;
• Ukucwangciswa okulula;
• Ubomi benkonzo ende;
• Iqondo eliphantsi lokuxhatshazwa kwamanzi ;
• Ukuthembeka.

Ingqungquthela eyona nto iyinkunzi enkulu. Oku kukhokelela kwiindleko eziphezulu zezinto, ngokukodwa ezinkulu, kuba ixabiso elikhulu lezinto ezifunekayo ukwenzela ukwenziwa kwazo. Kwakhona ufanele ukuphawula ukugqoka okukhawulezayo kweempawu.

Iintlobo

I-splue-flanged valve ifumaneka kwiinguqulelo ezahlukeneyo. Amadivaysi ahlukaniswe ngodidi ngokulandela ulwalathiso lwezenzo-ezifanayo kunye neempendulo. Ikhetho lokugqibela limile kwaye lihamba ngokuhambelanayo nomgca omkhulu. Izixhobo ezifanayo zifakwe kwi-angle ye-angle kwaye aziphazamisi ukuhamba, ngaphandle kokuba zisesimweni esifanelekileyo.

Kukho ukwahlula kweempawu ezakhayo - ezi ziyi-slayidi, ibhola kunye nemimiselo enemibala. Ezi zokugqibela zivalivali zokuvala eziqhelekileyo. Ziyasebenza kakuhle, zivimbela uhlobo lwe-perpendicular, kodwa zihluke kwisisindo.

Ukwakhiwa kwesiteyimu kufana nokufaniswa kwezinto zomkhaya zoluhlobo olufanayo. Izixhobo ezisetyenziswa kakhulu ziyi-DM 50 ngenxa yexabiso eliphantsi. I-Damper flange i-DN 100 ine-disk ekhethekileyo, ebandakanya iipayipi kunye ne-spring spring. Njengomgaqo, ifakwe kwiipayipi zeoli kunye namanethiwekhi asegesi.

Ukwahlula ngendlela yolawulo:

• Izixhobo ezigcinwe ngesandla. Ulawulo lwalo hlobo lwenziwa ngesandla ngokuguqula isicaciso esithile okanye i-valve. Nangona kunesidingo sokusebenzisa umzamo omkhulu wokwenza umzimba, abayidingi ukugcinwa kwaye abanqabile ukusilela.
• Umbane wesandla. Uye wakha umbane wamandla wokulawula. Inkqubo ikhiyiwe ngokuzimela, emva kokucofa iqhosha.

Izimo zokusebenza

Isango elihlangeneyo lisebenza kwiindidi zengcinezelo ezahlukileyo, inqanaba eliphezulu lifikelela kumawaka eunithi. Iqondo lokushisa liphakathi kwama-+200 no -50 degrees. Izixhobo zensimbi zenkxaso zibonakaliswe yimpawu eziye zandiswa, ngokukodwa, ukusebenza ngezinto ezinobungozi zingenzeka kwii-+400 degrees, kwaye isithuthi esisetyenziswayo esinokuthutha sinokushisa kwe-+270 degrees Celsius.

I-valve ye-flange ye-flange yenziwa ngokubanzi ngezinto eziphathekayo ezifana nentsimbi kunye nentsimbi. Eli pharamitha kwileyibhile yedayibrari. Naliphina iimveliso ezixutywe ngamacenge kufuneka zikhethwe ngokuchanekileyo ngokwemilinganiselo elawulwa ngamaphepha akhethekileyo. Okokuqala kukho, ubukhulu bomda wepastim echaphazelekayo kuthathelwa ingqalelo. Ukuba kukho na ukungahambelani nalo mqathango, ukunxibelelana kubonakala kungenakwenzeka. Ukuba umkhiqizo wensimbi we-flang ne-DN 80 okanye i-DN 50 isetyenzisiwe ukunyuka, i-flange ekhokelela kumbhobho wecala kufuneka ibe neeparitha ezifanayo. Ngexesha elifanayo, i-valve yesango le-flanged, ene-sliding spindle eyenziwa ngentshukumo yokuguquguqulela eyenziwa xa kuvula, ingaveliswa ngobukhulu obuhlukahlukeneyo. Ubungakanani obukhulu bufikelele kwi-1500 mm, ukulungelelanisa kuncinci kune-25 mm.

Ububanzi besicelo

Iziganeko ze-DM 80 kunye ne-DN 50 zaza ziba zixhaphake kwiipayipi zesekondari kunye namasebe angasemva kwezi nkqubo. Ukongeza, zisetyenziselwa kwiinkqubo ezinkulu zasekhaya, iipompo kunye namagumbi okubilisa. I-valve ye-Flanged 100 inkulu kwaye ifakwe kwi-heat ephezulu kunye neepayipi zokuhambisa amanzi. Iimveliso ze-DN 200 zisetyenziselwa kuphela kwiimeko zoshishino kwiinkqubo eziphambili zogonyamelo, ngelixa ukufakela kwazo ezinkulu iibholtshi ezikhethekileyo zisetyenzisiweyo. Iindleko zokuqiniswa zixhomekeke kubini kwimilinganiselo nakwimpawu zokuyila. Kwakhona, ixabiso lezinto ezisetyenziselwa ukwenziwa kubalulekile.

Ukufakwa

Ukufakwa kweemveliso kwenziwa ngeekimu eliqhelekileyo. Ngexesha elifanayo, umsebenzi wenziwa lula ngamacenge e-welding kwiipayipi okanye iipavini zokuvala. Ngaphandle koko, abasebenzi baza kudibanisa ngokuzimeleyo iiplavishini ezineengxenye ezongezelelweyo kunye nokudibanisa izinto ezithile zombhobho. Le nkqubo idinga iindleko ezinkulu zemali kunye nexesha, kwaye ibonakalisa ubunzima obuninzi, ukungaphumeleli kwinto engakhokelela kwiingxaki ngexesha lokusebenza. Oku kubaluleke kakhulu kwi-industry.

Ngomncedisi we-raber seal, uphawu lwentsimbi luyanda. Ifakwe kwisitishi esiseplate plate. Ngapha kwicala eliphambili leplani akufuneki kubekho umonakalo kunye nayiphi na enye umonakalo, ngaphandle koko kunokwenzeka ukuba uxinzelelo kunye nokuphumelela kwenkqubo. Ngaphantsi komqathango wokusebenza ngxinzelelo oluphezulu lwexinzelelo lwentloko le nto inemiphumo emibi.
