Definitions
- the present invention relates to a filling connector, a valve, a pressure fluid container, a method and a filling plug using such a connector.
- the invention relates more particularly to a filling connection for a container of pressurized fluid intended to cooperate with a conditioning outlet to permit the filling of said container, the connection comprising a body defining an internal filling circuit between an upstream end intended to be connected. at a conditioning outlet and a downstream end intended to be connected to a receptacle, the connection comprising a movable isolation valve relative to a seat between an upstream closing position of the circuit and a downstream opening position of the circuit, said valve isolation device being biased towards its upstream position by a return member, the connection further comprising a dust-proof valve disposed upstream of the isolation valve, said dust-protection valve having a downstream end and being movable relative to the body between an upstream position of closure of the upstream end of the circuit and a downstream position opening of the upstream end circuit, said dust gate being biased to its upstream position by at least one return member.
- the present invention relates in particular to a filling connection comprising in series, from upstream to downstream, a dust cover and an isolation valve (the terms “upstream” and “downstream” refer to the direction of flow of the gas during filling).
- the dust cover is provided in particular to form a barrier upstream of the isolation valve to prevent or limit the intrusion of particles or dust that can alter the sealing of said isolation valve.
- the filler connections have a dust cap that retracts into contact with the end of the conditioning plug to allow the filler plug to sink into the filler connector to actuate the isolation valve located downstream in the filling connection.
- This generally provides good protection against the intrusion of foreign bodies into a filling connection.
- this protection is usually not sufficient because, when the dust seal is open, the filling plug that enters the filling fitting downstream of the dust cover can bring particles. Pollution of the isolation valve may result in a significant leakage rate during the service life of the product on which the filler fitting is mounted. This is explained by the fact that the sealing area of the polluted insulation valve (dust, particles, ...) loses much of its sealing. This risk of intrusion of particles is increased when the filling connection is vertical (filling from above).
- a known solution consists in providing a filter for solid particles in the connection, upstream of the isolation valve. This makes it possible to retain particles or dust upstream of the isolation valve but does not make it possible to actuate the opening of the isolation valve by mechanical contact (the filter effectively forming a mechanical barrier for a valve lifter).
- Another solution is to provide a filter downstream of the isolation valve. This allows the mechanical actuation of the isolation valve and protects dust downstream of the isolation valve (the interior of the valve and the inside of the container). However, the upstream end of the isolation valve is then subject to pollution by particles or dust that may affect its sealing.
- the management of the seal between the outside of the filling plug (i.e. filling tool) and the filling connection is also problematic.
- the fill plug includes seals that cooperate with the fill connector. These seals are highly stressed during successive filling operations. This requires frequent changes of the seals.
- WO2009101350 discloses a device for filling and dispensing gas from a pressurized gas tank comprising a withdrawal conduit provided with a pressure reducer and two valves arranged in series and operable by a user system for the withdrawal of gas. To fill the reservoir, a bypass is carried out on a portion of the withdrawal conduit forming a filling channel bypassing one of the two valves and the expansion valve of the withdrawal conduit.
- An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
- connection according to the invention is essentially characterized in that the dust cover is selectively movable downstream, ie:
- non-contact opening the upstream end of the circuit, in which the downstream end of the dust cover does not push the upstream end of the isolation valve, the upstream end of the valve insulation being capable of being pushed towards its downstream opening position circuit by pressurized fluid entering through the open upstream end of the circuit, either in
- the dust gate having one or more passages for guiding at least a portion of the flow of fluid passing from upstream to downstream through the body of said dust cover, the check valve; dust comprising a first and a second concentric parts that can be moved relative to each other in the upstream-downstream direction.
- the dust gate guides and forces the flow of gas entering during the filling during its transit downstream.
- the passage ducts passing through the dust cover can in particular reduce the turbulence of the gas during filling. In this way, the vibrations generated are also reduced.
- a convergence of the flow (s) passing through the dust cover can make it possible to accelerate the flow of gas and to concentrate it towards a central zone of the passage, in particular at the level of the opening of the seat (upstream portion of the downstream isolation valve). ).
- This configuration saves at least part of the valve spring filling gas flow. This guiding of the filling gas can also make it possible to direct the flow of gas towards the zone forming the seat for the downstream isolation valve, favoring its cleaning with each filling. This reduces the risk of leakage from a soiled isolation valve seat.
- the dust seal valve in two distinct parts that are relatively mobile downstream makes it possible to provide a static seal between the filling clamp and the inlet of the connection and at the same time to provide dynamic actuation distinct from the isolation valve.
- the isolation valve is selectively pushed downstream (towards its open position) preferably by a movable portion of the dust cover).
- This part of the dust cover that actuates (pushes) the isolation valve does not provide sealing but is under a sealed atmosphere through another static part of the conditioning outlet. That is to say that the moving part that opens the isolation valve does not require a dynamic seal, the seal of the intake of conditioning remains static. This protects the seal from wear and other dynamic stresses.
- the configuration thus makes it possible to significantly improve the safety of the bottle during its multiple refills.
- This architecture also protects the isolation valve during successive filling operations.
- the upstream dust cover protects the downstream isolation valve against dust, but also protects the downstream isolation valve from direct contact with the end of a filling plug.
- this dual-slide architecture movable along a single axis forms an effective protection mechanism in a filling process for improved protection of the downstream isolation valve.
- the sliding dust cover can allow the opening of the upstream of the connection while
- the arrangement of the upstream dust cover and the downstream isolation valve also easily cooperate with conditioning sockets ensuring the opening of the downstream isolation valve via a flow of pressurized gas delivered into the connection (instead of mechanical contact).
- the dust gate regulates the flow of incoming gas during filling because the gas is forced through the body of the dust cover. This advantageously regulates the flow of gas towards the downstream part by minimizing the turbulence that is harmful to the mechanics of the isolation valve.
- the arrangement of the double check valve connection in series thus guarantees a high protection of the isolation valve against dirt and offers sequences of openings that adapt to different types of fillings.
- the invention offers great security in the opening / closing sequences of the filling connection.
- the filling according to the invention preserves the tightness of the connector during the life of the fitting.
- the upstream dust cover valve can advantageously participate in the mechanical opening of the downstream isolation valve by transmitting an upstream to downstream opening force. That is, in certain filling configurations, the dust cover may forming a motion transmitting member between a conditioning plug and the downstream isolation valve.
- the movable dust cover valve can ensure an opening upstream of the connector allowing the opening of the downstream isolation valve with the pressure of the filling gas (depending on the pressures and calibration of the valves).

- the mechanical movement transmission for selectively controlling the opening or closing of the downstream isolation valve

- the upstream end 104 of the dust cover 10, 100 can be pushed downstream by the gas flow itself (symbolized by arrows).
- the downstream end 101 of the valve 10, 100 dust cover can then mechanically push (pressure P) the valve 7 isolation.
- the dust cover 10, 100 is open (O) mechanically by a conditioning intake 1 1 (pressure P) but the isolation valve 7 is opened (O) not by the downstream end 101 of the valve 10, 100 dust cover but by the force exerted by the pressure of the incoming gas.
- the opening of the connection during a filling can be obtained by a sequential opening of the two valves 10,100; 7 in series (first the valve 10, 100 dust cover and then the valve 7 insulation).
- the isolation valve 7 is closed again automatically by the action of the spring 9 when the mechanical and / or fluidic force exerted on the upstream part of the valve 7 becomes lower. at a certain threshold.
- the isolation valve 7 is closed in principle before the flap 10, 100 dust cover is closed again.
- the structure according to the invention also makes it possible to set up filling procedures that are particularly effective in terms of safety for the operators providing the filling and for the end users of the tap equipped with such a coupling.
- valve 10, 100 movable dust cover adopts, during its movement, at least two sealing positions to secure the filling.
- valve 10, 100 dust cover is moved downstream and opens upstream of the circuit 6 without the isolation valve 7 is open (see Figure 9).
- opening position (0) of the valve 10 upstream 100 and closing (F) of the valve 7 downstream, the chamber located upstream of the valve 7 isolation can be evacuated (low pressure determined) for example by a filling tool for performing tests prior to filling. In this configuration it is indeed possible to measure any leaks from the valve 7 insulation.
- the isolation valve 7 can also be opened to ensure filling and / or to purge the circuit 6 and the bottle before filling (see, for example, the configuration of FIG. but with an inverted gas flow in case of purging).
- the isolation valve 7 can be closed and the valve 10, 100 dust cover can be kept open (see Figure 9) to achieve possible end-of-filling tightness tests such as those described above prior to filling.
- the filling method according to the invention thus makes it possible to improve the protection of the seal of the pollution seal valve (metal particles, dust, etc.) via the movable dust cover displaced during filling.
- the mechanical thrust of the isolation valve 7 remains possible but only via the valve 10, 100 dust cover.
- the filling method according to the invention thus makes it possible to improve the safety of filling by actuating the two-valve mechanism in series described above.
- the invention is advantageously applicable to filling connections and filling systems for pressurized gas cylinders for example between 150 and 750 bar) equipped with valves with integrated pressure reducers or with removable expansion valves.
- the filling connection can also possibly be the gas withdrawal connection.
