Muva nje, endaweni yokusebenzela ye-Jinbin, iqoqo lama-valve esango lama-slide angu-200×200 lipakishwe futhi laqala ukuthunyelwa. Lokhuslayida i-valve yesangoyenziwe nge-carbon steel futhi ifakwe amasondo e-worm manual.

I-valve yesango lesilayidi semanuwali iyisisetshenziswa se-valve eqaphela ukulawulwa kokucisha kwe-medium ngokusebenza mathupha. Isakhiwo sayo esiyinhloko siqukethe umzimba we-valve, ipuleti lesango, isondo lesandla kanye nendlela yokudlulisela. Umzimba we-valve wenziwa kakhulu ngezinto ezingagugi njengensimbi ekhonjiwe, i-carbon steel noma insimbi engagqwali. Ingaphezulu lepuleti lesango licutshungulwa kahle noma lihlotshiswe ngamalayini angagugi, angakwazi ukujwayela indawo yokudlulisa yemidiya ehlukene. Uma kuqhathaniswa nama-valve amasango kagesi noma we-pneumatic, imikhiqizo yezandla inezici zesakhiwo esihlangene, ukufakwa okulula kanye nezindleko zokunakekelwa okuphansi, futhi ifaneleka ngokukhethekile kumasistimu amapayipi amancane naphakathi nendawo noma izimo ezinezidingo eziphansi zokuzenzekelayo.

Mayelana nezici zokusebenza, izinzuzo eziyinhloko zamasango ama-slide enziwa ngesandla zibonakala ngezinhlangothi ezintathu: Okokuqala, zinokusebenza okuhle kakhulu kokuvala. Indawo yokuxhumana phakathi kwesango nomzimba we-valve isebenzisa ukuvala kwenjoloba noma idizayini yokufaka uphawu eqinile yensimbi, engavimbela ngempumelelo ukuvuza kothuli, izinto eziyimbudumbudu noketshezi olubolayo, futhi ingcindezi yokuvala emile ingafinyelela ngaphezulu kuka-0.6MPa. Okwesibili, inamandla okushintsha cishe izinga lokugeleza. Ngokulawula ukuphakama nokwehliswa kwepuleti lesango, izinga lokugeleza elimaphakathi lingalawulwa ngaphakathi kwebanga lokuvula lika-10% ukuya ku-90%, lihlangabezane nezimfuneko zokulawula isivinini esidlulisa impahla ekukhiqizweni kwezimboni. Okwesithathu, umsebenzi wokuvala ukuphepha uthembekile. Uma ivalwe ngokugcwele, ingamelana nokucindezela kokusebenza kwesistimu yamapayipi, iqinisekise ukuphepha kokugcinwa kwezinto zokusebenza noma ukuphatha amaphutha nokuvimbela izingozi zokukhiqiza ezibangelwa ukugeleza okuphakathi nendawo.

Ezisetshenziswa ezingokoqobo, ukukhethwa kwamavalvu esango lamaslayidi kufanele kunqunywe ngokuphelele ngokusekelwe kumapharamitha afana nezici zemaphakathi (izinga lokushisa, usayizi wezinhlayiyana, ukugqwala), ububanzi bepayipi (DN50-DN1000), kanye nokucindezela kokusebenza. Isibonelo, lapho uphatha izinto ze-viscosity ephezulu, idizayini yeplate yesango enobubanzi obukhulu kufanele ikhethwe ukuze kuvinjelwe ukunamathela kwempahla nokuvala. Ukuze kuthuthwe izinto ezisezingeni lokudla, insimbi engagqwali kufanele isetshenziswe futhi ifakwe esibukweni ukuze ihlangabezane nezindinganiso zokuhlanzeka. Ekusetshenzisweni kwansuku zonke, ukusebenzisa njalo amafutha kumshini wokudlulisela kanye nokuhlanza izinsalela ezivela ebusweni bepuleti lesango kungandisa kakhulu impilo yayo yesevisi futhi kuqinisekise ukusebenza okuzinzile kwesikhathi eside.

Amavalvu e-Jinbin abekhiqiza amavalvu embonini asezingeni eliphakeme ahlukahlukene iminyaka engama-20 (Abakhiqizi Bevalve Yesango Leslayidi). Uma unezidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo kungakapheli amahora angama-24!(Intengo Yevalve Yesango Lesilayidi)
