Tech/Engineering - 专利 | | English英语词条或短语： check dart | An apparatus according to claim 7, wherein the at least one check valve (160) comprises a soft elastomeric seat (164), a hard stainless steel seat (166) disposed beneath the soft elastomeric seat (164) and a stainless steel **check dart** (168), which is initially sealed against the soft seat (164) by a spring (170).
Il s'agit d'un dispositif de détente de pression |
| | 写给提问者或来自提问者的留言Gerard Renard: 17:12 Dec 7, 2007: à mon avis, il doit y avoir une analogie avec check valve (clapet antiretour)
Gerard Renard: 19:01 Dec 7, 2007: Je me demande s'il ne s'agirait pas d'un pointeau anti-retour. Est-ce que cela dit quelque chose à quelqu'un?
bohy: 00:00 Dec 8, 2007: Is this text already translated from another language?
Gerard Renard: 08:18 Dec 8, 2007: No, this comes from an original patent.
Gerard Renard: 08:19 Dec 8, 2007: Moreover, I would like to have another translation than "clapet anti-retour" since I already have this translation for "check valve" in the same document

| | clapet anti-retour [à ressort] | 说明：
While I know that they are referring to certain piece of metal attached to a spring to seal the valve, I cannot find a reference that reflects a piece of metal with that shape or use. Instead, I just find references for the part that closes the valve, which is of course, the "clapet anti-retour." The Weatherford site below contains two very good pictures of check valves with check darts. The pictures will be even larger if you copy them and put them into a Word document. The Wikipedia article has schemata for several different types of "clapets anti-retour" but not for this type. Still, you might find the article helpful.
When the gas-lift valve is open, the upstream (typically casing) pressure on the check valve is higher than the downstream (typically tubing) pressure. The higher upstream pressure depresses the spring-loaded dart, allowing the injection gas to flow through the check valve and into the production tubing. If the downstream pressure is greater than the upstream pressure, flow across the check dart causes the dart to seat, which prevents backflow. http://www.weatherford.com/weatherford/groups/public/documen...

CLAPET ANTI-RETOUR – CHECK VALVE
[see site for additional valves]
http://www.dassault-aviation.com/services/fr/transverse/lexi...
SPM's Dart Style Check Valves are flow control devices that permit flow in one direction but stop flow in the opposite direction. Generally used in well service applications, the dart check valve is placed in the treating line to allow flow to the well but isolates any back flow upstream of the valve. This provides a safety device at various locations in the flow line and assures that pressure and fluid cannot backup into the manifold area or into the pumps.

Mining - A valve having a lidlike piece hinged on one side within a chamber that permits the flow of a fluid or gas to proceed in one direction only. Usually, the check valve on the pickup end of a drill-pump suction hose is a clack-type valve. Also called chock valve; flap valve; flapper valve;foot valve.
Translations for "clack valve"; alternative meanings/domain in parentheses.
French - clapet de retenue, clapet (clapper), robinet d'essai. (various references)
German - Ventil (air-valve, gate, outlet, piston, safety valve, tube, valve, vent), Rueckhaltklappe (backwater flap, non-return valve), Prüfhahn (check valve, test cock), Klappenventil (clapper, **dart valve**, flat valve, valve), Klappe (back, can it, clack, clapperboard, flap, key, leaf, lid, patch, shutter, Sidegate, strap, swat, tab, tailgate, trap, trapdoor, valve).

Given that the Webster's reference above says that a German "klappenventil" is also a dart valve, I decided to check the glossaries for a German to French translation and found the following:

The dart of a dart check valve appears to be just called a "clapet." Autrement dit, le clapet anti-retour (ou de non-retour) à ressort utilise un clapet pour l’ouvrir ou le fermer. I've checked all the cool names like "flèche," "fléchette," "dard," and "aile." It's not "clapet à pointeau," which is a needle valve.
I did find another schema of a dart check valve that has a dart in a different shape than the first dart valve that I posted. It is very similar in appearance to the schema for the "limiteur de pression" shown in the Wikipédia article. That schema clearly labels the dart as a "clapet."
Dart Check Valves - see schema
Low-inertial dart desilgn – Hollow dart and fixed stem minimize pressure required to start flow. Non-metallic brushing reduces friction, increasing stem life.

Limiteur de pression - see schema
Un limiteur de pression est constitué de différents composants:
• le corps
• le clapet anti-retour conique
• le ressort
Si c'est un limiteur de pression réglable, on trouve de plus une vis de réglage.

• Le ressort
• Le corps
