4. Ithiyori yomsebenzi

Ivalve yokujonga ivula ngokuzenzekelayo kwaye ivale idiski ukuthintela ukuhamba okuphakathi ngasemva ngokuhamba okuphakathi.

5. Imigangatho yevalvu esebenzayo kodwa ayiphelelanga apha:

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

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

(5) GB/T 12235-1989 (6) GB/T 12236-1989

(7) GB/T 9113.1-2000 (8) GB/T 12221-2005 (9) GB/T 13927-1992

6. Ukugcinwa kunye noLondolozo kunye noFakelo kunye nokusebenza

6.1 Ivalve kufuneka igcinwe kwigumbi elomileyo nelingena umoya.

6.2 Iivalvu eziphantsi kogcino lwexesha elide kufuneka zihlolwe kwaye zicocwe rhoqo, ngakumbi ubuso obuhlalayo ukuthintela ukonakaliswa kwayo, kwaye ubuso obuhlalayo kufuneka bugqunywe ngeoyile enqanda umhlwa.

6.3 Ukumakishwa kweValve makutshekishwe ukuhambelana nokusetyenziswa kwayo.

6.4 Umgodi wevalvu kunye nomphezulu wokutywina kufuneka uhlolwe phambi kofakelo kwaye kususwe ukungcola ukuba kukho.

6.5Icala lotolo kufuneka lifane nela ngakulo.

6.6 Ukuphakamisa ivalve yokujonga idiski emileyo kufuneka ifakwe ngokuthe nkqo kumbhobho. Ivalve yokujonga idiski ethe tyaba kufuneka ifakwe ngokuthe tye kumbhobho.

6.7 Ukungcangcazela kufuneka kuhlolwe kwaye utshintsho loxinzelelo oluphakathi kwemibhobho kufuneka luqatshelwe ukuthintela ukusebenza kwamanzi.

  1. Iingxaki ezinokwenzeka, izizathu kunye nomlinganiselo wokulungisa

Iingxaki ezinokwenzeka

Oonobangela

Umlinganiselo woLungiso

Idiski ayikwazi ukuvula okanye ukuvala
  1. Ingalo ye-rocker kunye ne-pin shaft iqine kakhulu okanye kukho into ebambekayo
  2. Iibhloko zokungcola ngaphakathi kwevalve
  3. Jonga imeko yomdlalo
  4. Susa ukungcola
  

Ukuvuza
  1. Ibholt ayiqini ncam
  2. Flange itywina umonakalo umphezulu
  3. Umonakalo weGasket
  4. Qinisa ngokulinganayo
  5. Lungisa
  6. Faka indawo ye-gasket entsha
  

Ingxolo kunye neVibration
  1. Ivalve ikufuphi kakhulu nempompo
  2. Uxinzelelo oluphakathi aluzinzanga
  3. Ukutshintshela kwenye indawo iivalvu
  4. Susa ukuguquguquka koxinzelelo
  

8. Iwaranti

Emva kokuba ivalve isetyenziswe, ixesha lewaranti yevalve ziinyanga ezili-12, kodwa alidluli kwiinyanga ezili-18 emva komhla wokuhanjiswa. Ngexesha lewaranti, umenzi uya kubonelela ngenkonzo yokulungisa okanye iinxalenye ezisecaleni ngaphandle kwentlawulo ngenxa yomonakalo ngenxa yezinto, umsebenzi okanye umonakalo ngaphandle kokuba umsebenzi uchanekile.
