Kushanda uye Maintenance Manual yeCheck Valves

1. Nzvimbo

Iwo maDN mitsara anosanganisira DN15mm~600mm(1/2”~24”) uye PN siyana kubva kuPN1.6MPa~20MPa(ANSI CLASS150~1500) dzakarukwa, dzakachinjika, BW uye SW swing uye nekusimudza cheki vharafu.

2.Kushandisa:

2.1 Iyi valve ndeyekudzivirira yepakati inoyerera ichidzokera kumashure mupombi system.

2.2 Valve zvinhu zvinosarudzwa zvinoenderana nepakati.

2.2.1WCB vharuvhu yakanakira mvura, chiutsi uye mafuta svikiro nezvimwe.

2.2.2SS vharafu inokodzera ngura yepakati.

2.3 Tembiricha:

2.3.1Common WCB inokodzera tembiricha -29℃ ~+425℃

2.3.2Alloy valve inokodzera tembiricha≤550℃

2.3.3SS vharafu inokodzera tembiricha-196 ℃ ~+200℃

3. Chimiro uye maitiro ekuita

3.1 Mamiriro ekutanga akaita senge pazasi:

3.2 PTFE uye flexible graphite inogamuchirwa kune inokuvadza gasket kuti ive nechokwadi chekuisa chisimbiso.

4. Dzidziso yebasa

Cheki vharafu inovhura otomatiki uye inovhara dhisiki kudzivirira yepakati kuyerera kumashure nekuyerera kwepakati.

5. Miyero yevharuvhu inoshanda asi isina kuganhurirwa ku:

(1) API 6D-2002 (2) ASME B16.5-2003

(3) ASME B16.10-2000 (4) API 598-2004

6. Kuchengeta & Maintenance & Installation & Operation

6.1 Ivhavha inofanira kuchengetwa muimba yakaoma uye ine mhepo yakanaka.

6.2 Mavharuvhu ari pasi pekuchengetedza kwenguva refu anofanirwa kuongororwa uye kucheneswa nguva nenguva, kunyanya kugara kumeso kudzivirira kukuvara kwayo, uye chiso chekugara chinofanira kuputirwa ne ngura inodzivirira mafuta.

6.3 Kumaka vharafu kunofanirwa kutariswa kuti ienderane nekushandiswa.

6.4 Ivhavhavhavha uye yekuvharisa nzvimbo inofanirwa kuongororwa isati yaiswa uye kubvisa tsvina kana paine.

6.5Arrow direction inofanira kufanana negwara rekuyerera.

6.6 Kusimudza vertical disc cheki vharafu inofanira kuiswa yakatwasuka kune pombi. Kusimudza horizontal disc cheki vharafu inofanira kuiswa yakatwasuka kune pombi.

6.7 Kudengenyeka kunofanirwa kutariswa uye pombi yepakati pressure shanduko inofanirwa kucherechedzwa kudzivirira kuitika kwemvura.
