Panguman ed pressure na panlukas na safety valve (set pressure):
Diad loob na nibaga ya working pressure range, say opening pressure et nayarin i-adjust diad pangi-rotate ed adjusting screw pian nauman so spring preload compression. Ekalen so taklay na balbula, lukasan so lock nut, insan i-adjust so adjusting screw. Unona, paabebaen so inlet pressure pian ontaynan so balbula.
No abeba so presyon na panlukas, ipeket so adjusting screw ya paonlad relo; no atagey so presyon na panlukas, paulyanan itan ya onkontra ed relo. Kayari na pangi-adjust ed nakaukolan ya pressure na panlukas, i-tight so lock nut tan i-install so cover cap.
No say nakaukolan ya presyon na panlukas et onlampas ed presyon na kimey na spring, kaukolan ya salatan so sananey a spring na matukoy a presyon na kimey, insan i-adjust itan. Kayari na pangisaliwan ed spring, nepeg ya umanen so mipetekan a data ed nameplate.
No i-adjust so opening pressure na safety valve, nepeg ya imanoen iray onggendan a punto:
No say medium pressure et asingger ed cracking pressure (anggad 90% na cracking pressure), ag nepeg ya i-rotate so adjusting screw, pian ag-on-rotate so disc tan ag-onderal so sealing surface.
Pian naseguro ya susto so opening pressure value, saray medium conditions ya uusaren parad adjustment, singa say medium type tan medium temperature, et nepeg ya asingger ed aktual ya kondisyon na pantratrabaho. No manguman so klase na medium, lalo la no manguman manlapud liquid phase ya anggad gas phase, say opening pressure et mabetbet ya manguman. No ontagey so temperatura na trabaho, onkupas so presyon na panag-crack. Kanian, no i-adjust itan ed temperatura na kuarto tan usaren ed atagey a temperatura, say set pressure value ed room temperature et nepeg ya mas atagey na daiset nen say opening pressure value na bola.
Panguman ed relief valve discharge pressure tan reseating pressure:
Kayari na pangi-adjust ed opening pressure, no say discharge pressure odino reseating pressure et ag makaabot ed saray kakaukolanen, sarag mon usaren so adjusting ring ed valve seat pian na-adjust. Ekalen so fixing screw na adjusting ring, tan isuksok so manipis ya iron bar odino arum nin kagawaan manlapud akalukas ya screw hole, insan saray ngipen na gear ed adjusting ring et nayarin igalaw pian say adjusting ring et onliko ed kawigi tan kawanan.
No say adjusting ring et ipaarap ed kawanan, ontagey so posisyon to, tan onkupas so discharge pressure tan reseating pressure; diad kasunian, no say adjusting ring et ipaarap ed kawigi, onkupas so posisyon to, tan onkupas so discharge pressure tan reseating pressure. Ondarakel so presyon na yurongan. Diad kada pangi-adjust, say laknab na panag-ikot na adjusting ring et nepeg ya aliwan baleg (kaslakan et diad loob na 5 ngipen).
Kayari na kada pangi-adjust, say fixing screw et nepeg ya ipeket pian say sampot na screw et walad kanal ed baetan na duaran ngipen na adjustment ring pian ag-onliber so adjustment ring, balet ag nepeg ya i-exert so lateral pressure ed adjustment ring. Insan manggawa na action test. Parad kaligenan, antis ya ibalikas so adjustment ring, nepeg ya nabawasan so inlet pressure na safety valve (maslak et abeba nen say 90% na opening pressure), pian ag biglan nalukasan so balbula legan na adjustment tan saray aksidente.
Imanoen ya posible labat ya gawaen so safety valve discharge pressure tan reseating pressure test no say flow rate na gas source et baleg la pian ag-onlukas so valve (salanti, no naabot lay rated discharge capacity na safety valve).
Balet, say kapasidad na test bench ya kaslakan ya uusaren pian naseguro so opening pressure na safety valve et melag a tuloy. Diad sayan panaon, say balbula et ag sigpot ya nalukasan, tan say pressure na reseating to et aliwan tua. No i-calibrate so opening pressure ed ontan ya test bench, pian napatnagan so take-off action, say adjustment ring et kaslakan ya i-adjust ed medyo atagey a posisyon, balet ag-itan matukoy ed aktual ya kondisyon na panag-operate na balbula, tan say posisyon na adjustment ring et nepeg ya i-adjust lamet.

Kayari na pangi-adjust ed amin ya safety valves, nepeg ya selyadoan iratan na lead pian ag-onuman ya ag-inisip iray in-adjust ya kondisyon. No ompaway so safety valve ed pabrika, kaslakan ya i-adjust itan na normal ya temperatura na dagem unong ed sankatageyan a limitasyon (salanti, atagey a presyon) na balor na working pressure level, likud ed saray espisyal ya sirkumstansya.
Kanian, saray manguusar et kaukolan dan i-adjust unong ed aktual iran kondisyon na pantratrabaho. Insan mo selyadoen lamet.

Say Tianjin Tanggu Water Seal Valve Co., Ltd. et sakey a teknolohikal ya maaligwas ya elastic seat valve ya onsusuporta ed saray negosyo, saray produkto et elastic seat wafer butterfly valve,lug butterfly valve,double flange concentric butterfly valve,double flange eccentric butterfly valve, balance valve,wafer dual plate check valvetan arum nira. Diad Tianjin Tanggu Water Seal Valve Co., Ltd., proud kami ed pangiter mi na saray sankaabigan ya produkto ya makaabot ed sankatageyan ya estandarte na industriya. Lapud dakel so klase na balbula tan kagawaan mi, napanmatalkan yo kamin mangiter na perpekton solusyon parad sistema na danum yo. Kontakin kami natan pian naamtaan so nipaakar ed saray produkto mi tan no panon mi kan natulongan.
