Isigama seNkcazelo yeValve

1. Ivalvu

icandelo elihambayo lesixhobo esidibeneyo soomatshini esisetyenziselwa ukulawula ukuhamba kweendaba kwimibhobho.

2. Aivalvu yesango(ekwaziwa ngokuba yivalvu etyibilikayo).

Isiqu sevalvu siqhuba isango, elivulekayo nelivalekayo, phezulu nasezantsi ecaleni kwesihlalo sevalvu (umphezulu wokuvala).

3. Iglobhu, ivalvu yeglobhu

Isiqu sevalvu siqhuba ivalvu yokuvula nokuvala (idiski), ehamba phezulu nasezantsi ecaleni kwe-axis yesihlalo sevalvu (umphezulu wokuvala).

4. Iswitshi yoMbhobho woMbhobho

ivalvu etshintsha ukuhamba noxinzelelo ngokutshintsha indawo enqamlezileyo yetshaneli ngokusebenzisa icandelo lokuvula nokuvala (idiski).

5. Ivalvu yebhola

ivalvu yebhola eyivalvu evaliweyo kwaye ijikeleza ecaleni kwegophe elihambelana nepaseji.

6. Ivalvu yebhabhathane

ivula kwaye ivale ivalvu ejikeleza i-axis esisigxina (ivalvu "yebhabhathane").

7. Ivalvu ye-diaphragm (ivavu ye-diaphragm)

Ukuze kwahlulwe indlela yokusebenza kwisixhobo, uhlobo lokuvula nokuvala (uhlobo lwe-diaphragm) luhamba lunyuka luze luhle nge-axis yesiqu sevalvu.

8. Ivalvu ye-cock okanye ye-plug

ivalvu yokujika enokuvulwa nokucinywa.

9. (Jonga ivalvu, jonga ivalvu)

Uhlobo oluvulekileyo (idiski) lusebenzisa amandla esixhobo ukuthintela ngokuzenzekelayo isixhobo ukuba singahambi kwicala elichaseneyo.

10. Ivalvu yokhuseleko (ngamanye amaxesha ibizwa ngokuba yivalvu yokunciphisa uxinzelelo okanye ivalvu yokhuseleko)

Uhlobo lwediski evulekileyo Ukukhusela umbhobho okanye umatshini, uxinzelelo oluphakathi kwisixhobo luvuleka ngokuzenzekelayo kwaye lukhuphe xa ludlula ixabiso elichaziweyo kwaye luvale ngokuzenzekelayo xa luwela ngaphantsi kwexabiso elichaziweyo.

11. Isixhobo sokunciphisa uxinzelelo

Uxinzelelo lwesixhobo sombane luyancitshiswa ngokucinezela iindawo zokuvula nezokuvala (iidiski), kwaye uxinzelelo olungasemva kwevalvu lugcinwa ngokuzenzekelayo ngaphakathi koluhlu olumiselweyo ngesenzo esithe ngqo soxinzelelo olungasemva kwevalvu.

12. Umgibe womphunga

ivalvu ethintela umphunga ukuba ungaphumi ngelixa ikhupha i-condensate ngokuzenzekelayo.

13. Ivalvu yokukhupha amanzi

iivalvu ezisetyenziswa kwimibhobho yoxinzelelo kunye neebhoyila zokukhupha amanzi amdaka.

14. Utshintsho oluphantsi loxinzelelo

iivalvu ezahlukeneyo ezine-PN1.6MPa uxinzelelo oluqhelekileyo.

15. Ivalvu yoxinzelelo oluphakathi

Iivalvu ezahlukeneyo ezine-nominal pressure PN≥2.0～PN＜10.0MPa.

16. Iswitshi yoxinzelelo oluphezulu

iivalvu ezahlukeneyo ezine-PN10.0MPa uxinzelelo oluqhelekileyo.

17. Ivalvu yoxinzelelo oluphezulu kakhulu

iivalvu ezahlukeneyo ezine-PN 100.0 MPa uxinzelelo oluqhelekileyo.

18. Iswitshi yobushushu obuphezulu

isetyenziselwa uluhlu lweevalvu ezinobushushu obuphakathi obungaphezulu kwama-450°C.

19. Ivalvu engaphantsi kwe-zero (ivalufu ekrwada)

iivalvu ezahlukeneyo zobushushu obuphakathi ukusuka kwi -40 ukuya kwi -100 degrees Celsius.

20. Ivalvu yeCryogenic

Ifanelekile kwiivalvu zobushushu obuphakathi bazo zonke iintlobo ezinomlinganiselo wobushushu obuyi--100°C.
