Pilot self-operated pressure regulator structure
Pilot self-operated pressure regulator molao-motheo oa ho sebetsa
1.Qalong, spool e kholo ea valve ea ZZYVP Pilot self-operated pressure regulator e lula e koetsoe tlas'a matla a ts'ebetso ea spring11.Director 08 e lula e butsoe tlas'a matla a ts'ebetso ea selemo sa 17.
2. Sekhahla se phalla ka har'a valve ea taolo tlas'a tataiso ea motsu, ka valve ea liphallelo 06, e phallela ho motsamaisi 08, ka motsamaisi 08 le throttle valve 13, e phalla ho actuator 07 diaphragm kamoreng e ka tlase.Khatello e tsoang kamoreng ea diaphragm ea actuator07 e ka tlase e ntse e phahama.Sephahla se seholo se tla buleha tlas'a khatello.Mocheso o phallela ka har'a valve, ka pompo ea khatello ea 09 le 21, ebe o phalla ka kamoreng ea diaphragm ea actuator07 ka holimo le mookameli oa 08 diaphragm ka holimo.
3.Ha khatello ea P2 ka mor'a hore valve e phahame, khatello ea P4 e sebetsang ho actuator 07 diaphragm kamoreng e ka holimo e ntse e phahama, tekanyo e kholo ea ho bula valve e fokotseha le khatello ka mor'a hore valve e fokotsehe (phetoho ea pele).Ho sa le joalo, khatello ea P6 e sebetsang ho motsamaisi 08 diaphragm kamoreng e ka holimo e ntse e phahama 'me tekanyo ea ho bula ea 08 ea fokotseha.Khatello ea P5 ka kamoreng ea diaphragm ea actuator 07 e ka tlase e ea fokotseha.The ZZYVP Pilot self-operated pressure regulator degree main valve opening e ntse e fokotseha le ho feta mme khatello kamora hore valve e lule e fokotseha (tokiso e ntle).
4.Ha khatello ea P2 ka mor'a hore valve e fokotsehe, khatello ea P4 e sebetsang ho actuator 07 diaphragm kamoreng e ka holimo e fokotsa. Tekanyo e kholo ea ho bula valve e ntse e eketseha, 'me khatello ka mor'a hore valve e phahame (phetoho ea pele).Ho sa le joalo, khatello ea P6 ka kamoreng ea 08 ea diaphragm ka holimo e fokotseha, tekanyo ea 08 ea ho bula e ntse e eketseha, 'me khatello ea P5 ka kamoreng ea diaphragm ea actuator 07 e ka tlaase e ntse e phahama.Tekanyo e kholo ea ho bula li-valve e ntse e eketseha le ho feta mme khatello ka mor'a hore valve e lule e eketseha (tokiso e ntle).
5.Sehlopha se seholo sa valve sa ZZYVP Pilot se ikemetseng se laola khatello le mookameli oa 08 se ke ke sa khaotsa ho sebetsa ho fihlela se fihla ho boleng bo behiloeng.Ka nako ena, khatello ka mor'a valve e behiloe boleng, decompression e matla e ka phethahala.
