1. Uqhagamshelwano lweFlange
Le yeyona ndlela ixhaphakileyo yokudibanisa kwiivalvu.Ngokobume bomphezulu odibeneyo, unokwahlulwa ngokwezi ndidi zilandelayo:
● Uhlobo olugudileyo: lusetyenziselwa ivalve enoxinzelelo oluphantsi kwaye ilungele ukusetyenzwa.
● Uhlobo lwe-concave convex: uxinzelelo lokusebenza luphezulu, kwaye i-washer enzima ephakathi ingasetyenziswa.
● Uhlobo lwe-Tenon groove: iwasha ene-deformation enkulu yeplastiki ingasetyenziswa, esetyenziswa ngokubanzi kwindawo enokudleka kwaye inesiphumo esihle sokutywinwa.
● Uhlobo lwe-Trapezoidal groove: sebenzisa i-elliptical metal ring njenge-gasket, kwaye usebenzise i-valve enoxinzelelo olusebenzayo ≥ 64kg / cm2 okanye i-valve ephezulu yokushisa.
● Uhlobo lwelensi: igasket yimo yelensi, eyenziwe ngentsimbi.Kwivalve yoxinzelelo oluphezulu okanye ivalve ephezulu enoxinzelelo olusebenzayo ≥ 100kg / cm2.
● Uhlobo lwe-O-ring: Le yindlela entsha yokudibanisa i-flange, ephuhliswa ngokuvela kwee-rubber ezahlukeneyo ze-O-rings.Ithembeke ngakumbi kune-gasket eqhelekileyo ye-flat kwisiphumo sokutywinwa.
2 Uqhagamshelwano ngomsonto
Le yindlela elula yokudibanisa, esetyenziswa ngokuqhelekileyo kwiivalve ezincinci.Kukho iimeko ezimbini:
● Ukutywinwa ngokuthe ngqo: imicu yangaphakathi nangaphandle idlala indima ngokuthe ngqo ekutywineni.Ukuqinisekisa ukuba akukho kuvuza kwindawo edibeneyo, i-oyile ekhokelayo, i-thread hemp kunye nebhanti ye-polytetrafluoroethylene eluhlaza ihlala isetyenziselwa ukuzaliswa.Phakathi kwabo, ibhanti ye-polytetrafluoroethylene eluhlaza isetyenziswa ngokubanzi.Esi sixhobo sinokumelana ne-corrosion, isiphumo esihle sokutywinwa, ukusetyenziswa ngokufanelekileyo kunye nokugcinwa.Xa uqhaqha, inokususwa ngokupheleleyo, kuba yifilimu engancangathi, ephezulu kakhulu kwi-oyile ekhokelayo kunye ne-thread hemp.
● Ukutywinwa ngokungathanga ngqo: amandla okuqinisa intambo adluliselwa kwi-gasket phakathi kweenqwelo-moya ezimbini ukwenza i-gasket idlale indima yokutywina.
3 Uqhagamshelwano lweFerrule
Unxibelelwano lwe-ferrule luye lwaphuhliswa kwiminyaka yakutshanje e-China.Iinzuzo zale fomu yoqhagamshelwano zezi zilandelayo:
● Umthamo omncinci, ubunzima obulula, isakhiwo esilula kunye nokuqhawula lula;
● Amandla oqhagamshelwano oluqinileyo, uluhlu olubanzi lwesicelo, kwaye lunokumelana noxinzelelo oluphezulu (1000 kg / cm2), ukushisa okuphezulu (650 ° C) kunye nempembelelo ye-vibration;
● Uluhlu lwezinto eziphathekayo lunokukhethwa, olufanelekileyo kwi-anti-corrosion;
● Iimfuno zokuchaneka kokulungiswa azikho phezulu;
● Ilungele ukufakwa komgangatho ophezulu.Okwangoku, uhlobo loqhagamshelo lwe-ferrule lusetyenzisiwe kwiimveliso ezincinci zevalvu yezibuko eTshayina.
4 Uqhagamshelo lokubamba
Le yindlela yokudibanisa ngokukhawuleza, idinga kuphela iibholiti ezimbini, ezifanelekileyo kwiivalve eziphantsi zoxinzelelo ezihlala zichithwa.
5 Uqhagamshelo lobuqu lwangaphakathi
Ukwahluke kwezinye iindlela zokudibanisa, amandla angaphandle asetyenziselwa ukuchasana noxinzelelo oluphakathi ukufezekisa ukutywinwa.Umsesane wokutywina ufakwe kwi-cone yangaphakathi, yenza idigri ethile kunye nobuso obuchasene nephakathi.Uxinzelelo oluphakathi ludluliselwa kwi-cone yangaphakathi, kwaye emva koko kwindandatho yokutywina.Kwi-conical surface ene-angle esisigxina, amacandelo amabini ayenziwa, enye ihambelana nomgca ophakathi womzimba we-valve kwaye enye icinezelwe kudonga lwangaphakathi lomzimba we-valve.Inxalenye yokugqibela ngamandla aziqinisayo.Uxinzelelo olukhulu oluphakathi, kokukhona uziqinisa ngamandla.Ngoko olu hlobo loqhagamshelwano lufanelekile kwivalve yoxinzelelo oluphezulu.Xa kuthelekiswa noqhagamshelo lwe-flange, inokugcina izinto ezininzi kunye nabasebenzi, kodwa ifuna amandla athile okuqinisa kwangaphambili, ukuze isetyenziswe ngokuthembekileyo xa uxinzelelo kwivalve lungekho phezulu.
Kukho iindlela ezininzi zokudibanisa i-valve, umzekelo, ezinye iivalve ezincinci ezingafuneki ukuba zisuswe zifakwe kwimibhobho;ezinye iivalvu ezingezizo ezentsimbi zisebenzisa uqhagamshelo lwesokhethi, njl. njl. Abasebenzisi bevalvu kufuneka baphathwe ngokwemiqathango ethile.
