Zeziphi iindlela ezimbini ezidityanisiweyo eziqhelekileyo kwiivalvu? Ukwakhiwa kwesakhiwo kunye nomgaqo wokusebenza wevalve yeplagi evaliweyo yombane Uqhagamshelo ngemisonto Le yindlela elula yokudibanisa, ehlala isetyenziselwa iivalve ezincinci. Kukho iimeko ezimbini: 1, ukutywinwa ngokuthe ngqo: imicu yangaphakathi nangaphandle idlala indima yokutywinwa. Ukuze kuqinisekiswe ukuba i-joint ayivuzi, ngokuphindaphindiweyo ngeoli ye-lead, i-linoleum kunye ne-PTFE i-raw material ezaliswe; ibhanti Ptfe ekrwada, ukusetyenziswa ukwanda ukuthandwa; Esi sixhobo sinokumelana ne-corrosion elungileyo, isiphumo esihle sokutywinwa, ukusetyenziswa kunye nokugcinwa kwecala Imidibaniso enemisonto Le yindlela elula yokudibanisa kwaye isoloko isetyenziswa ngeevalvu ezincinci. Kukho iimeko ezimbini ezongezelelweyo: 1, ukutywinwa ngokuthe ngqo: imicu yangaphakathi neyangaphandle idlala indima yokutywinwa. Ukuze kuqinisekiswe ukuba i-joint ayivuzi, ngokuphindaphindiweyo ngeoli ye-lead, i-linoleum kunye ne-PTFE i-raw material ezaliswe; ibhanti Ptfe ekrwada, ukusetyenziswa ukwanda ukuthandwa; Esi sixhobo sinokumelana ne-corrosion, isiphumo esihle sokutywinwa, kulula ukuyisebenzisa kunye nokugcinwa, kwaye xa idityanisiwe, inokususwa ngokupheleleyo, kuba ifilimu engeyiyo i-viscous, ingcono kakhulu kuneoli ehamba phambili kunye ne-linoleum. 2. Ukutywinwa ngokungathanga ngqo: amandla e-screw tightening adluliselwa kwi-washer phakathi kweendiza ezimbini, ukwenzela ukuba i-washer idlale indima yokutywina. UKUNIKEZELWA KWENTSALELA EQINILE, UBUCHULU, OKANYE NAYAYIPHI NA INTO ESINGAPHANDLE KUMGCA KUNOKUKUTHINTA UKUSEBENZA KWESIVIVINYO kwaye konakalise kanobom Amacandelo abalulekileyo e-valve. Ingaphakathi lombhobho kufuneka licocwe kakuhle ngomoya okanye ngomphunga. XA UCELA UMbhobho, MLINGANISELA UBUKHULU NOBUDE BEMICHUPHO UKUNQANDA UKUGCINWA UMbhobho NGEZItulo kunye neediski. Iziphelo zokucoca ngokucokisekileyo ukukhusela nayiphi na intsimbi eyingozi okanye iidiphozithi zentsimbi. Sebenzisa iteyiphu yeteflon okanye izinto zokuncamathelisa zemibhobho ukwenza iiweld ezinamandla. Sebenzisa izinto zokuncamathelisa zemibhobho kuphela ngamanani amancinci kwimisonto yombhobho, kodwa hayi *** kwimisonto yevalvu. UNGAVUMELI naziphi na izinto zokuncamathelisa ZOMbhobho ukuba zigxuphuleke EMZIMBENI UKUNQANDA umonakalo kwi-DISC NESIHLALO. Ngaphambi kokufakela, cima ukuhamba ngevalve ukuze ivalve isebenze kakuhle. Vala ivalve ngokupheleleyo phambi kofakelo. Beka isitshixo kwintloko ye-hex bolt kufuphi nombhobho ukuphepha ukuguqulwa okunokwenzeka. Emva kokufaka ivelufa, XHASA UMbhobho: I-SAGGING umbhobho inokonakalisa ivalve kwaye ibangele ukusilela. Uqhagamshelwano lweflange Le yeyona ndlela ixhaphakileyo yoqhagamshelwano lwevalvu. Ngokwemilo yendawo edibeneyo, inokuthi ihlulwe ngolu hlobo lulandelayo: 1. Uhlobo oluthambileyo: lusetyenziselwa iivalve ezinoxinzelelo oluphantsi. Ukulungiswa okufanelekileyo kwe-2, i-concave kunye nohlobo lwe-convex: uxinzelelo oluphezulu olusebenzayo, lunokusetyenziswa kwi-washer enzima 3. I-Tenon kunye nohlobo lwe-groove: i-gasket ene-deformation yeplastiki enkulu ingasetyenziselwa kwimidiya ephazamisayo, kwaye umphumo wokutywinwa ungcono. I-4, i-trapezoidal groove: sebenzisa i-oval metal ring njenge-washer, esetyenziselwa uxinzelelo lokusebenza ≥64 kg / cm2 valve, okanye i-valve ephezulu yokushisa. I-5, uhlobo lwe-lens: i-washer i-lens shape, eyenziwe ngesinyithi. Kwiivalve zoxinzelelo oluphezulu kunye noxinzelelo olusebenzayo ≥100 kg / cm2, okanye iivalve eziphezulu zokushisa. I-6, uhlobo lwe-ring ye-O: Olu luhlobo olutsha lokudibanisa i-flange, luphuhliswa ngokubonakala kwazo zonke iintlobo ze-rubber ye-O ring, inokwethenjelwa ngakumbi kune-washer yeflethi ngokubanzi kwisiphumo sokutywinwa. Ukuqinisekisa ukufakela okufanelekileyo koqhagamshelo lweflange, landela la manyathelo. Okokuqala ucoce ngokucophelela amajoyina, uze udibanise ngokukhululekileyo iibholiti ezimbini okanye ezintathu kwisiseko. Emva koko, faka ngokucophelela i-spacer kwi-joint. I-bolt ephantsi inceda ukubeka i-gasket kwaye uyigcine kwindawo. Iibholiti zokufaka kufuneka emva koko ziqiniswe ngokunqamlezayo kune-WRAPAROUND, enceda ukuphelisa uxinzelelo oluxinana kakhulu. Emva kokusetyenziswa okuqhelekileyo ixesha elithile, khangela ukuba zonke iibholiti ziqinisiwe kwaye ziphinde ziqiniswe njengoko kuyimfuneko. Ivalve yesango yombane evaliweyo yenziwe ngumzimba wevalve engundoqo kunye neyoncedisayo, ipleyiti yevalve, ijoyinti yokwandiswa, umkhono osisigxina, i-electro-hydraulic push rod clamping mechanism, ukufakelwa kombane ohambahambayo, umda, umzimba wevalve osekhohlo nasekunene kunye nezinye izinto. Ukuvala ivalvu: i-electro-hydraulic push rod drive spring clamping mechanism, ipleyiti yevalve isusiwe, endaweni, ukuhamba isiqalo sombane, qhuba ipleyiti yevalvu ihamba ukusuka evulekileyo ukuya ekuvaleni, endaweni, i-electro-hydraulic push rod reverse motion, spring clamping mechanism ngokuzenzekelayo. ibambeke endaweni, ukuphela kwevalve yokuvala. Ivalve evulekileyo ijika ngokuphambeneyo. Ukwakhiwa kwesakhiwo kunye nomgaqo wokusebenza wevalve yeplagi evaliweyo yombane ivelufa yeplagi evaliweyo yenziwe ngumzimba oyintloko kunye nomncedisi wevalve, ipleyiti yevalvu, ijoyinti yokwandiswa, umkhono osisigxina, i-electro-hydraulic push rod clamping mechanism, ukufakelwa kombane ohambahambayo, umda, ivalve yasekhohlo nasekunene. umzimba kunye namanye amalungu. Ukuvala ivalvu: i-electro-hydraulic push rod drive spring clamping mechanism, ipleyiti yevalve isusiwe, endaweni, ukuhamba isiqalo sombane, qhuba ipleyiti yevalvu ihamba ukusuka evulekileyo ukuya ekuvaleni, endaweni, i-electro-hydraulic push rod reverse motion, spring clamping mechanism ngokuzenzekelayo. ibambeke endaweni, ukuphela kwevalve yokuvala. Ivalve evulekileyo ijika ngokuphambeneyo. Vula iGATE VALVE, IVALIWE ISANGO IFANELE I-METALLURGY, I-CHEMICAL INDUSTRI, umbhobho weGAS KAMASIPALA, ngokuhambelana NE-GB6222-86 "IMIMISELO YOKHUSELEKO LWEGAS YESHISHINI". Xa i-valve ye-PLUG EVALIWEYO YOMXENO IKWISIMO ESIVALIWEYO, sinqumle ngokupheleleyo i-medium kumbhobho, ukufezekisa ukutywinwa kokuvuza kwe-zero, imveliso yombane evaliweyo yeplagi ingaba kwisiza, ukusebenza okude, yigesi efanelekileyo kwaye iyingozi, inetyhefu. Umbhobho wegesi ukhuseleko womnatha izixhobo zokwahlula. Ulwakhiwo olucwangcisiweyo lwevalve yesango yombane evaliweyo Iimpawu eziphambili zentsebenzo yevalve yesango yombane evalelweyo: Idayamitha yegama (mm) : DN800-3600 Uxinzelelo lwegama (MPa) : 0.05, 0.1, 0.25 Ubushushu obusebenzayo (℃) : ≤260 Indawo esebenzayo: igesi kunye nezinye igesi enetyhefu, eyingozi, enokutsha Ukudibanisa umgangatho weflange: ngokuhambelana ne-GB9115-2000 Iimpawu zesakhiwo sevalve yesango lombane elivaliweyo: Ivalve yeplagi yenziwe ngumzimba wangaphambili, umzimba ongasemva, ipleyiti yevalve, i-telescopic body, ukutywinwa kwesobunxele nasekunene. ibhokisi, ipleyiti edlulayo kunye nepleyiti eyimfama, isixhobo sokutshintsha, kunye nesixhobo sokuncamathela esikhululayo. Isixhobo sokugoba esikhululayo sevalve yesinyithi siqhutywa sisixhobo sombane. I-sprocket, ikhonkco kunye ne-screw nut pair ziqhagamshelwe, kwaye ukwandiswa kwemvulo kuqhutywa ukuze kuqatshelwe ukugonywa okanye ukukhulula isitulo sotywino somzimba wevalvu. Ivalve ithatha i-SPROCket yohlobo lwe-multi-point clamping mechanism, ikhonkco lokutywina litywina elinamacala amabini, lifakwe kwipleyiti yevalve, ukutywinwa kuthembekile kwaye kulula ukukutshintsha. Umzila wesikhokelo esiphezulu sepleyiti yevalve uxhotyiswe nge-longitudinal kunye ne-transverse move mechanism, kwaye icala lixhotyiswe nge-spring mechanism kunye nevili lomda. Xa umatshini wokubambelela ukhutshiwe ukukhulula ipleyiti yevalvu, indlela yasentwasahlobo iphakamisa ipleyiti yevalvu ukuya kwivili elilinganiselweyo.
