Valve Basic

A balbulaet sakey a control device parad linya na pluido. Say manunan kimey to et say pangikonekta o pangiputot ed sirkulasyon na pipeline ring, panguman ed direksion na agos na medium, pangi-adjust ed pressure tan agos na medium, tan protektaan so normal ya operasyon na pipeline tan kagawaan.

一．Klasipikasyon na saray balbula

Unong ed usar tan gagala to et nayarin naapag ed:

1. Shut-off valve: putoten o ikonekta so pipeline medium. Singa say: gate valve, globe valve, ball valve, butterfly valve, diaphragm valve, plug valve.

2. Check valve: amperen so medium ed pipeline ya onagus ya paulyanan.

3. Distribution valve: umanen so direksion na agos na medium, ibunog, ibiig odino ilaok so medium. Singa say distribution valves, steam traps, tan three-way ball valves.

4. Regulating valve: i-adjust so pressure tan flow na medium. Singa say pressure reducing valve, regulating valve, throttle valve.

5. Safety valve: amperen so medium pressure ed device ya onlampas ed nibaga ya balor, tan mangiter na proteksion ed overpressure.

二. Saray manunan parametro nabalbula

1. Say nominal a diametro na balbula (DN).

2. Say nominal ya presyon na balbula (PN).

3. Pressure tan temperatura na balbula: No say temperatura na balbula et onlampas ed temperatura na nominal pressure, say sankatageyan ya presyon na balbula et nepeg ya nabawasan unong ed satan.

4. Pananguman na yunit na presyon na balbula:

5. Say onaplikan paraan nabalbula:

Saray industrial valve et uusaren ed petrolyo, industriya na kemikal, metalurhiya, kuryente, enerhiya nukleyar tan arum niran industriya. Saray media ya ipapasa et kaiba iray gas (dagem, singaw, ammonia, coal gas, petroleum gas, natural gas, tan arum nira); saray likido (danum, likidon ammonia, larak, asido, alkali, tan arum nira). Arum ed saratan et makaderal a singa saray machine gun, tan arum et radioactive a tuloy.
