Kwetfulwa kwetintfo tekuvala emavalvu—TWS Valve .

Tintfo tekuvala ivalve tiyincenye lebalulekile yekuvala ivalve. Yini tintfo tekuvala valve? Siyati kutsi valve kuvala indandatho tintfo tihlukaniswe ngetigaba letimbili: insimbi kanye non-metal. Lokulandzelako singeniso lesifishane setimo tekusebentisa tintfo letehlukene tekuvala, kanye netinhlobo tevalve letisetjentiswa kakhulu.

1. Irabha leyentiwe

Tintfo letiphelele te rubber leyentiwe letifana nekumelana ne oyili, kumelana nekushisa kanye nekumelana nekugcola tincono kunaleto te rubber yemvelo. Ngalokuvamile, kushisa kwekusetjentiswa kwerabha yekwentiwa ngu t≤150°C, bese kushisa kwerabha yemvelo ngu t≤60°C.Irabha isetjentiselwa kuvala emavalvu emhlaba,ivalvu yesango lehleti ngerabha, emavalvu e-diaphragm,rubber lehleti ivalvu yevivane, rubber ahleli swing hlola valve (hlola emavalvu), emavalvu e-pinch kanye nalamanye emavalvu lanemfutfo lomncane PN≤1MPa.

2. Inayiloni

Nylon has timphawu coefficient friction encane kanye nekumelana lokuhle kwekugcola. I-Nylon isetjentiswa kakhulu kumavalvu ebhola kanye nemavalvu emhlaba ngekushisa t≤90°C kanye nekucindzeteleka lokubitwako PN≤32MPa.

3. I-PTFE

PTFE isetjentiswa kakhulu emavalvu emhlaba,emavalvu esango, emavalvu ebhola, njll ngekushisa t≤232°C kanye nemfutfo lobitwako PN≤6.4MPa.

4. Insimbi lephosiwe

Insimbi lephosiwe isetjentiselwaIvalvu yesango, valve yemhlaba, valve yepulagi, njll yekushisa t≤100°C, umfutfo lobitwako PN≤1.6MPa, igesi kanye nawoyela.

5. Inhlanganisela yeBabbitt

Babbitt inhlanganisela isetjentiselwa ammonia umhlaba valve nge lokushisa t-70 ~ 150 ° C kanye umfutho egama PN≤ 2.5 MPa.

6. Inhlanganisela yelitfusi

Tintfo letivamile tetinhlanganisela telitfusi ngu 6-6-3 welitfusi lelithini kanye nelitfusi le manganese lelingu 58-2-2. I-Copper alloy inekumelana lokuhle nekugcoka futsi ilungele emanti kanye nemphunga ngekushisa t≤200°C kanye nekucindzeteleka lokubitwako PN≤1.6MPa. Livame kusetjentiswa ku .emavalvu esango, emavalvu emhlaba,hlola emavalvu, emavalvu epulagi, njll.

7. Insimbi lengagucuki ye-Chrome

Emazinga lavame kusetjentiswa e Chromium stainless steel ngu 2Cr13 na 3Cr13, leseyicinywe futsi yashiswa, futsi inekumelana lokuhle nekugcola. Ivame kusetjentiswa kumavalvu etindzaba letifana nemanti, umfutfo kanye ne petroleum ngekushisa t≤450°C kanye nekucindzeteleka lokubitwako PN≤32MPa.

8. Insimbi lengagucuki yekhromiyamu-nikikheli-thayitaniyamu

Lizinga lelivame kusetjentiswa le chromium-nickel-titanium yensimbi lengagucuki ngu 1Cr18Ni9ti, lenekumelana lokuhle nekugcola, kumelana nekuguguleka kanye nekumelana nekushisa. Ilungele umfutfo, i-nitric acid kanye naletinye tindzaba letinekushisa t≤600°C kanye nemfutfo lobitwako PN≤6.4MPa, usetjentiselwa i-valve ye-globe, i-valve yebhola, njll.

9. Insimbi lene-nitride

Lizinga lelivame kusetjentiswa lensimbi le nitrided ngu 38CrMoAlA, lenekumelana lokuhle nekugcola kanye nekumelana nekuklwebheka ngemuva kwekwelashwa kwe carburizing. Kuvame kusetjentiswa evalve yesango lesikhulumi samandla ngekushisa t≤540°C kanye nemfutfo lobitwako PN≤10MPa.

10. Kufaka ibhori

Boronizing ngco kucubungula indzawo yekuvala kusuka kumphahla yemtimba wevalve noma umtimba we disc, bese yenta kwelashwa kwendzawo ye boronizing, indzawo yekuvala inekumelana lokuhle kwekugcoka. Isetjentiswa esiteshini samandla blowdown valve.
