VALVE APPARATUS TO PREVENT CONTAMINATION OF FLUID IN A FLUID REGULATOR |
摘要 |
<p>Valve apparatus to prevent contamination of a fluid in a fluid regulator (300) are described. An example valve apparatus described herein includes a housing (402) disposed within a fluid flow passageway of the fluid regulator to define a low-pressure side (405) of the fluid flow passageway and a high-pressure side (403) of the fluid flow passageway. The housing has a bore (406) that at least partially defines the fluid flow passageway when coupled to the fluid regulator. The housing has a movable valve assembly (408) disposed within the bore via a non- threaded connection in fluid communication with the low-pressure side of the fluid flow passageway and external threads (404) to threadably couple the housing to an opening (342) of the fluid regulator. A seal system (428,442) prevents impurities from flowing between the high-pressure side of the fluid flow passageway and the low-pressure side of the fluid flow passageway.</p> |
