Uxinzelelo oluphezulu ivelufa yesango elisicaba

Ingcaciso yeMveliso:

Iivalve zesango elisicaba zilungele ioyile, igesi yendalo, amanzi, ioyile kunye neminye imibhobho eneklasi 150 ~ 900/PN 1.0 ~ 16.0 MPa kunye nobushushu obusebenzayo obungu-29 ~ 121℃, kwaye zisetyenziselwa ukunqumla okanye ukudibanisa okuphakathi imibhobho.

Ubungakanani besicelo:

Iivalvu zesango ezisicaba zilungele igesi yendalo, i-petroleum, ishishini lemichiza, ukukhuselwa kwendalo, imibhobho yasezidolophini, imibhobho yerhasi kunye neminye imibhobho yothutho, iinkqubo zokukhupha umoya kunye nezixhobo zokugcina umphunga, kwaye zisetyenziswa njengezixhobo zokuvula nokuvala. Ivalve yesango enye ye-Z43 enomngxuma wokuphambukela ifanelekile kumbhobho omde wokusetyenziswa nokucoca irhasi yendalo.

Iimpawu zesakhiwo:

1. Isihlalo sevalve sithatha i-O-ring seal kunye nesakhiwo sesitulo sevalve edadayo ngamandla okuqinisa, ukuze indawo yokungena kunye nokuphuma kwevalve yesango elisicaba itywinwe ngokuphindwe kabini; Ukongeza, i-torque yokuvula kunye nokuvala kwesi sakhiwo yi-1/2 kuphela yeevalvu eziqhelekileyo, ezinokuvula ngokulula kunye nokuvala ivalve.
2. Xa ivuliwe ngokupheleleyo, umjelo ulungile kwaye uthe tye, i-coefficient yokumelana nokuhamba incinci kakhulu, kwaye akukho kulahlekelwa kwengcinezelo. Umbhobho
Ezi-3 zinokucocwa ngeebhola zoboya. Isakhiwo sokupakisha kunye nekhono lokuzitywina samkelwa, esingadingi ukulungiswa rhoqo, kwaye ukuvulwa kunye nokuvala kukhanya kakhulu, kwaye ukusebenza kokutywinwa kunokwethenjelwa. Isakhiwo esincedisayo sokutywinwa kwenaliti yegrisi icwangciswe kwibhokisi yokuhlohlwa, ke ngoko ukusebenza kokutywina kuthembekile ngokupheleleyo, kwaye kuphumelela ngenene ukuvuza kwe-zero. Isombulula into engalunganga yokuba ukupakishwa kwevalve yendalo yonke yeyona nto ilula ukuvuza.
4. Xa i-valve ye-flat gate ivaliwe, inokukhupha ngokuzenzekelayo uxinzelelo oluphezulu kwindawo yangaphakathi, ukuqinisekisa ukhuseleko lokusetyenziswa.
5. Isakhiwo esivaliweyo ngokupheleleyo, ukusebenza kakuhle kokukhusela, okunokuhlangabezana neemfuno zemozulu yonke.
1. Isakhiwo sokutywinwa kwesihlalo sevalve kufuneka sibe ne-elastic kunye namandla okuqinisa kwangaphambili, kunye nezihlalo zokutywina eziphezulu kunye nezantsi zingavalwa ngexesha elifanayo. Kuhlala kukho itywina lobuso ngobuso phakathi kwesitulo sevalve kunye nesitywina.
2. Isihlalo sevalve sinomsebenzi wokuzicoca ngokwaso, kwaye asihlanjwa ngokuthe ngqo ngokuhamba komoya xa ivalve ivuliwe okanye ivaliwe. Isihlalo sevalve kufuneka senziwe ngezinto ezithanjiswayo nezingaqhubi.
3. Ukungaphumeleli kwe-valve actuator akuyi kuchaphazela ezinye iindawo zevalve, kwaye ukugcinwa kunye nomsebenzi wokutshintshwa kungenziwa ngaphandle kokususa i-valve.
(1) Umkhono wedyokhwe ye-aluminiyam yedyokhwe yobhedu uxhotyiswe ngenaliti yokutyhalela ukunciphisa itorque yokusebenza. (2) ubude bomsonto wevalve ukuya kwisibiyeli; Nokuwelda indawo yesikhonkwane; Yiba uzinzo.
(3) Uxinzelelo lokutywinwa-isakhiwo esilula, esinesegmented retaining ring kunye nesilivere-plated low carbon steel gasket, eluncedo ukuqhaqha kunye nokuqaphela eyona seal yebhonethi.
(4) Isihlalo somsesane-Isitulo sesihlalo esidityanisiweyo si-perpendicular kumjelo wokuhamba kwaye kulula ukuyigcina.
(5) I-Actuator-Ezi zivalo zinokuthi zixhotyiswe ngombane, i-hydraulic okanye i-pneumatic actuators. Ngaphantsi kwe-DN300, ivili lesandla esiqhelekileyo lixhotyiswe, kwaye ngaphezulu kwe-DN350, indlela yokusebenza ye-helical gear ixhotyiswe.
(6) Idyokhwe-Idyokhwe ehlanganiswe ngokupheleleyo iphumelele uvavanyo lwe-seismic kwaye kulula ukuyigcina kunye nokufaka i-actuator.
(7) Idlala lengqula-ezimbini, idlala elizilungisayo ukuze liphephe ukukhutshwa.
8
(9) I-Disc-Spring-loaded disc inokuzilungisa ngokwayo, ukunciphisa imfuno ye-torque ye-actuator.
(10) Ukumisa okudibeneyo-isixhobo sokumisa isibiyeli sifakwe ngokudibeneyo ukubeka idiski yesibiyeli edityanisiweyo, esenza isihlalo sevalve sizinze kwaye sithembekile.
