Ivalvu yenaliti iyingxenye ebalulekile yesistimu yepayipi yokukala insimbi, futhi iyivalvu ekwazi ukulungisa ngokunembile futhi inqamule uketshezi.I-valve core iyikhoni ebukhali kakhulu, evame ukusetshenziselwa ukugeleza okuncane, igesi ephezulu yokucindezela noma uketshezi.Isakhiwo sawo sifana nevalvu yembulunga, futhi umsebenzi wayo ukuvula noma ukusika i-valve ukuze kungene ipayipi.
1. Ingxenye yokuvula neyokuvala ye-valve yenaliti iyikhoni ebukhali, ejikeleza ngokuphambene newashi lapho ivula futhi iwashi lapho ivala.
2. Isakhiwo sangaphakathi sifana naleso se-valve yokumisa, kokubili okuyi-inlet ephansi kanye ne-outlet ephezulu.Isiqu se-valve sishayelwa isondo lesandla.
Isimiso sesakhiwo se-valve yenaliti
1. I-valve yenaliti enekhava yevalvu kufanele ikhethelwe uhlelo lwamapayipi kanye nedivaysi ye-low-temperature medium.
2. Ohlelweni lwamapayipi lweyunithi yokuqhekeka kweyunithi yokucwenga uwoyela, ivalvu yenaliti yenduku yokuphakamisa ingakhethwa.
3. Amavalvu yenaliti azokwenziwa ngensimbi engagqwali ye-austenitic ene-PTFE njengendandatho yokuvala isihlalo sevalvu kumadivayisi namasistimu wamapayipi anemidiya egqwalayo njenge-asidi ne-alkali ohlelweni lwamakhemikhali.
4. Amavalvu ezinaliti zokuvala zensimbi kuya kwensimbi angakhethelwa amasistimu wamapayipi noma amadivaysi emidiya esezingeni lokushisa eliphezulu ezinhlelweni ze-metallurgical, izinhlelo zamandla, izitshalo ze-petrochemical kanye nezinhlelo zokushisisa zasemadolobheni.
5. Uma ukulawulwa kokugeleza kuyadingeka, igiya lezikelemu eliqhutshwayo, i-pneumatic noma i-valve yenaliti kagesi enokuvulwa okumise okwe-V ingakhethwa.
6. Ivalvu yenaliti enebhobo eligcwele kanye nesakhiwo esigcwele sokushisela iyosetshenziselwa ipayipi elikhulu likawoyela negesi yemvelo, ipayipi elizohlanzwa futhi ipayipi ligqitshwe ngaphansi komhlaba;Kulabo abangcwatshwe phansi, i-valve yebhola enoxhumo olugcwele lwe-welding noma uxhumano lwe-flange luzokhethwa.
7. I-valve yenaliti exhunywe nge-flange izokhethelwa ipayipi lokudlulisa kanye nempahla yokugcina kawoyela womkhiqizo.
8. Emapayipini egesi yasemadolobheni kanye negesi yemvelo, ama-valve yenaliti anoxhumano lwe-flange nokuxhumeka kwentambo yangaphakathi kuyakhethwa.
9. Kuhlelo lwepayipi le-oksijini lesistimu ye-metallurgical, i-valve yenaliti enokwelashwa okuqinile kokukhipha amafutha kanye nokuxhumeka kwe-flange kufanele kukhethwe.
10. I-valve yenaliti yakhiwe ngomzimba we-valve, i-cone yenaliti, ukupakisha kanye nesondo lesandla.
