Butterfly valve leh pipeline emaw hmanrua emaw inkara connection method thlan chu a dik leh dik loh chuan pipeline valve tlan, dripping, dripping leh leak theihna chance chu direct-in a nghawng dawn a ni. Valve connection hman tlanglawn tak takte chu: flange connection, wafer connection, butt welding connection, threaded connection, ferrule connection, clamp connection, self-sealing connection leh connection form dangte a ni.
A. Flange hmanga inzawmna
Flange connection a ni aflanged butterfly valve hmanga siam a nivalve body tawp pahniha flange nei, pipeline-a flange awmte nena inmil, flange-te bolt hmanga pipeline-a dah a ni. Valve-a connection form hman tam ber chu flange connection a ni. Flanges hi convex surface (RF), flat surface (FF), convex leh concave surface (MF), etc. ah then a ni.
B. Wafer inzawmna
Valve hi flange pahnih lai takah dah a ni a, valve body of thewafer hnim hring valve a nia tlangpuiin installation leh positioning awlsam zawk nan positioning hole a nei thin.
C. Solder hmanga inzawmna
(1) Butt welding connection: Valve body tawp pahnih chu butt welding mamawh angin butt welding groove-ah an siam a, chu chu pipeline-a welding groove-te nen a inmil a, welding hmangin pipeline-ah an nghet tlat a ni.
(2) Socket welding connection: Valve body tawp pahnih hi socket welding-a mamawh angin process a ni a, pipeline nen socket welding hmanga inzawm a ni.
D. Thread hmanga inzawmna
Threaded connection hi connection awlsam tak a ni a, valve te tak te tan pawh hman a ni fo. Valve body hi thread standard tin angin process a ni a, internal thread leh external thread chi hnih a awm bawk. Pipe-a thread awm nen a inmil. Threaded connection hi chi hnih a awm a:
(1) Direct sealing: A chhung leh pawn lam thread te hian direct in sealing role an nei a. Connection a leak loh nan lead oil, thread hemp leh PTFE raw material tape hmanga khat a ni fo a; chung zingah chuan PTFE raw material tape hi hman a ni nasa hle a; he material hian corrosion resistance tha tak a nei a, sealing effect tha tak a nei bawk. Hman leh dahkhawm a awlsam hle. Disassembling a nih chuan non-sticky film a nih avangin a chhuak vek thei a, lead oil leh thread hemp aiin a tha zawk hle.
(2) Indirect sealing: thread tightening chakna chu plane pahnih inkar gasket-ah a kal a, chutiang chuan gasket chuan sealing role a play a ni.
E. ferrule inzawmna
Ferrule connection hi tun hnaiah ka ramah chauh siam a ni. A inzawmna leh sealing principle chu nut chu tihkhauh a nih chuan ferrule chu pressure a awm a, chutiang chuan ferrule kil chu pipe pawn lam bang chhungah a seh a, ferrule pawn lam cone chunglam chu pressure hnuaiah joint nen a inzawm a ni. Taksa chhung lam chu tapered surface nen a inzawm tlat avangin leakage chu rintlak takin a veng thei a ni. Instrument valve ang chi te. Hetiang inzawmna chi hi a thatna chu:
(1) A lian lo hle a, a rit lo hle a, a structure a awlsam a, a disassembly leh a assembly awlsam bawk;
(2) Connection force chak tak, hmanna hmun zau tak, pressure sang tak do theihna (1000 kg/cm 2 ), temperature sang (650 ° C) leh shock leh vibration te
(3) Thil chi hrang hrang thlan theih a ni a, anti-corrosion atana tha;
(4) Machining dikna atana thil tul chu a sang lo va;
(5) Hmun sang taka dahna atan a remchang.
Tunah hian ka ram chhunga small-diameter valve product thenkhatah chuan ferrule connection form hi hman a ni tawh a.
F. Grooved inzawmna
Hei hi connection rang tak a ni a, bolt pahnih chauh a mamawh a, leha grooved end butterfly valve a nipressure hniam tak atan a tha hlebutterfly valve te pawh a awmchu chu tihchhiat fo thin a ni. sanitary valve ang chi te pawh a ni.
G. Chhungril lama mahni insiamthatna inzawmna
A chunga connection form zawng zawng hian external force hmangin medium pressure offset in sealing an nei vek a ni. A hnuaia tarlan te hi medium pressure hmanga self-tightening connection form tarlan a ni.
A sealing ring chu inner cone-ah dah a ni a, a sir chu medium lam hawiin angle engemaw zat a siam a ni. Medium pressure chu inner cone ah a kal a, chutah chuan sealing ring ah a kal leh bawk. Angle engemaw zat cone surface-ah chuan component force pahnih a lo piang a, pakhat chu The center line of the valve body chu pawn lam nen a inmil a, pakhat chu valve body chhung lam wall-ah a press a ni. A hnuhnung zawk chakna chu mahni inkharkhip chakna a ni. Medium pressure a san chuan self-tightening force a sang zawk thin. Chuvangin he connection form hi high pressure valve tan a tha hle.
Flange connection nena khaikhin chuan material leh manpower tam tak a humhim a, mahse preload engemaw zat a mamawh bawk a, chuvang chuan valve chhunga pressure a san loh hunah rintlak takin hman theih a ni. Self-tightening sealing principle hmanga siam valve te hi a tlangpuiin high-pressure valve an ni.
Valve connection chi hrang hrang a awm a, entirnan, valve te tak te thenkhat lak chhuah ngai lo chu pipe hmanga weld an ni a; non-metallic valve thenkhat chu socket leh a dangte hmanga inzawmkhawm a ni. Valve hmangtute chu an dinhmun bik a zirin enkawl tur a ni.
Thil chhinchhiah:
(1) Connection method zawng zawng hian a inmil standard a en tur a ni a, valve thlan chu dah a nih loh nan standard te chu a chiang tur a ni.
(2) A tlangpuiin, diameter lian pipeline leh valve chu flange hmanga inzawm a ni a, diameter te tak te pipeline leh valve chu thread hmanga inzawm a ni.
