Valve Basic

A balbulametung yang control device para keng fluid line. Ing kayang basic a obra yapin ing magkonekta o magputol keng sirkulasyun ning pipeline ring, magbayu keng direksyun ning danum ning medium, mag-adjust keng pressure ampo flow ning medium, ampo magprotekta keng normal a operasyun ning pipeline ampo ing kagamitan.

一．klasipikasyun da reng balbula

Agpang keng gamit ampo gamit malyari yang miyabe keng:

1. Shut-off valve: pututan o ikonekta ing pipeline medium. antimo: gate valve, globe valve, ball valve, butterfly valve, diaphragm valve, plug valve.

2. Check valve: pigilan ing medium keng pipeline na mamagus pabalik.

3. Distribution valve: alilan me ing direksyun ning danum ning medium, i-distribute, i-separate o isamut me ing medium. antimo reng distribution valves, steam traps, ampo reng three-way ball valves.

4. Regulating valve: i-adjust ing pressure ampo ing flow ning medium. antimo ing pressure reducing valve, regulating valve, throttle valve.

5. Safety valve: pigilan ing medium a pressure keng device na lumampas keng metung a ulaga, ampo mamye yang overpressure safety protection.

二. Basic parameters ningbalbula

1. Ing nominal a diametru ning balbula (DN).

2. Ing nominal a pressure ning balbula (PN).

3. Pressure ampo temperature rating ning valve: Nung ing working temperature ning valve lampas ya keng reference temperature ning nominal pressure, ing maximum working pressure na dapat mabawas ya.

4. Valve pressure unit conversion:

5. Ing applicable medium ningbalbula:

Deng industrial valves magagamit la keng petrolyu, chemical industry, metallurgy, electric power, nuclear energy ampo aliwa pang industriya. Deng media a dadalan kayabe la reng gas (angin, steam, ammonia, coal gas, petroleum gas, natural gas, atbp.); likidu (danum, likidung ammonia, laru, asidu, alkali, atbp.). Kalupa da reng machine gun deng aliwa kareti, at matas la radioactive deng aliwa.
