Valve-te sealing performance tha lo chinfelna rang tak engemaw zat

Valve quality tehna atana index lian ber pakhat chu valve sealing performance hi a ni. Valve sealing performance-ah hian a bik takin thil pahnih a awm a, chungte chu, internal leakage leh external leakage te an ni. Internal leakage tih hian valve seat leh closing part inkar sealing degree a kawk a, external leakage hian valve stem filling part leakage, middle flange gasket leakage leh casting part defect avanga valve body leakage a kawk bawk. Valve sealing performance a tha lo a nih chuan lungngai lutuk suh,chutiangrubber hmanga thut a ni a, butterfly valve a ni, gate valve nghet tak & . dual plate check valve a ni, a hnuaia method hi i lo enchhin hmasa thei ang.

1. Grinding dan tur

Fine grinding, traces tihbo, sealing clearance tihtlem emaw tihbo, sealing surface smoothness tihchangtlun, sealing performance tihchangtlun.

2. Use a unbalanced force chu sealing specific pressure method tihpun nan a hmang a ni

Valve body atanga sealing pressure siam actuator chu a chiang a, unbalanced force in valve core top opening trend a siam chuan valve body sealing force chu force pahnih in a tlahniam a, chu ai chuan pressure closing trend, valve core sealing force chu force pahnih sum a ni a, hei hian sealing specific pressure nasa takin a tipung a, sealing effect chu 5~10 aia tam a ni thei a hmasa aiin a let hnih zetin a sang zawk. General dg 20 single seal valve hi a hmasa ber a ni a, a tlangpuiin flow open type a ni a, sealing effect a satisfactory loh chuan flow closed type-a thlak a nih chuan sealing performance chu a let hnih a ni ang. A bik takin, two-position cut-off regulating valve hi a tlangpuiin flow closed type angin hman tur a ni.

3. Actuator sealing force hman dan tur siam that

Valve spool-a actuator sealing force tihchangtlun hi valve khar a nih theih nan, sealing specific pressure tihsan nan leh sealing performance tihchangtlun nan hmanraw hman tlanglawn tak a ni bawk. Thil tih dan tlangpui chu:

1 Moving spring hnathawhna hmun;

2 Stiffness spring te tak te hmang la;

3 Accessories dah belh, locator hmanga siam ang chi;

4 Air source pressure tihsan;

5 Thrust nasa zawk nei actuator-ah thlak rawh.

4. Use a seal pakhat, soft seal hman dan

Double seal-a hman regulating valve tan chuan single seal-ah a chantir thei a, a tlangpuiin sealing effect chu vawi 10 aia tam a ti tha thei a, unbalanced force a lian a nih chuan a inmil tur measures te chu dah belh tur a ni a, hard seal valve chu soft seal-ah thlak theih a ni a,duhA rilru a buai em em a, a rilru a hah em em bawk a, leh sealing effect chu vawi 10 aia tam a ti tha thei bawk.

5. Valve sealing performance tha tak hmang rawh

A tul chuan sealing performance tha zawk nei valve-a switch ngaihtuah tur a ni. Butterfly valve pangngai chu elliptical butterfly valve-ah thlak a nih chuan, chutah chuan cut-off butterfly valve pawh a hmang thei bawk a nih chuan,eccentric butterfly valve a ni, ball valve leh a bik taka siam cut-off valve te a ni.

Tianjin Tanggu Water Seal Valve Co., Ltd. ah hian industry standard sang ber nena inmil first-class product kan pe thei hi kan chhuang hle. Valve leh fitting hrang hrang kan neih avangin i tui system atana solution tha ber kan pe thei ang tih i ring thei ang. Kan thil siam chungchang leh kan tanpui theih dan tur hriat duh chuan vawiin hian min rawn biak theih reng e.
