Definitions

  • the present invention relates to a valve body and a trigger arrangement of at least one valve body according to the preamble of claims 1 and 10.
  • the figure 1 represents a triggering arrangement of several (here 4) devices whose discharge outputs (Sd1, Sd2, Sd3, Sd4) are coupled to distribution channels (Out1, Out2, Ou3, Out4) converging to a pipe (Out) d ejection of the agent.
  • the channels of distribution may provide check valves (Car_d1, Car_d2, Car_d3, Car_d4) in particular not to disturb the discharge profiles of each of the ejection devices and their respective valve body to be triggered in series.
  • the first ejection device comprising the first valve body (Co1) is called “master” because its valve trigger input (Ed1) is coupled to an actuator such as a solenoid (So1) or a generator. pressure / gas as the discharge device of the valve (V1).
  • the priming device can be designed differently to trigger an opening of the valve (V1), for example by means of a pneumatic, pyrotechnic and / or mechanical system resulting in setting the valve (V1) to open. discharge
  • the second ejection device comprising the second valve body (Co2) is called a "slave” because its valve triggering input (Ed2 or Ed2 ') is coupled to the pressure output (Sb1) of the first device " master ".
  • the triggering of the second device “slave” (downstream) is activated by a derivative output and taken on the discharge of the first device "master” ( upstream).
  • the tripping of the second valve (V2) is generated in pressure by means of an inlet (Ed2 ') of the second valve body (Co2) in addition to the tripping input (Ed2), the latter being usually provided for an autonomous gas / pressure generating system such as the solenoid (So1), said boss input (Ed2) being connected by the trigger channel (Cd2) and providing the role of the "slave” discharge device for discharging the second valve (V2).
  • the triggering input (Ed2) usually provided is thus sealed in a sealed manner by a threaded plug.
  • the second, third and fourth devices successively “slaves” have a shutter pressure (cap, hood, ...) on all their outputs (Sb2, Sb3, Sb4) usually coupled respectively by a bypass channel (D2, D3, D4) to their output channel (Cs2, Cs3, Cs4).
  • all the inputs / outputs may be an element attached to the valve body (Co1), or be integrated therewith.
  • An object of the present invention is to provide a simple geometry valve body, particularly by limiting the number of its inputs and outputs necessary for interconnection related to the triggering of at least two geometrically identical valve bodies, and independently of the fact that said valve bodies are associated with ejection devices of the type "masters" or "slaves".
  • this valve body should be easy to install and maintain, especially as it is integrated with an arrangement interconnecting multiple valve bodies. Principally, this amounts to limiting or even avoiding too many connection and / or closure means to be arranged on the inputs or outputs of the valve body, particularly for interconnections related to tripping of at least two geometrically identical valve bodies.
  • valve body should be able to suppress a redundant or periodic installation of priming devices, as shown in the figure 3 or 5 , by using a slaved cylinder triggered by the / said bottles (s) "master” to control a series of following bottles called “slaves", if for example the number of ejection devices exceeds 20.
  • valve body should be able to increase the dynamic conditions of triggering an arrangement comprising several ejection devices arranged in series.
  • the invention comprises two claims 1 and 10 respectively providing such a valve body and an arrangement of at least two valve bodies.
  • a set of subclaims also has advantages of the invention.
  • Figure 2 presents an arrangement of 4 mainly structured ejection devices according to the figure 1 , i.e. whose valve bodies (Co1, Co2, Co3, Co4) are coupled in series by means of a discharge tripping channel initiated by the first "master" type ejection device comprising the bottle (Bo1) and a valve body (Co1) according to the invention.
  • valve body according to the invention can be illustrated most clearly on the basis of the second, third or fourth valve body (Co2, Co3, Co4).
  • first valve body (Co1) is also designed to meet the requirements of the invention.
  • second valve body (Co2) according to the invention.
  • a "global" trigger channel (Cd1, R1, Cc12, Cd2, R2, Cc23, Cd3, R3, Cc34, Cd4) of all the ejection devices to be configured through the inputs and usual outputs (Edi, Sbi) (l ⁇ i ⁇ N) of said devices.
  • the specific inputs and outputs (Edi ', Sbi') for triggering the valve bodies are no longer necessary.
  • the geometry of the valve body is considerably simplified, as well as its design, manufacture and cost. Mounting efforts as well as the risks and cost of maintenance are also very advantageously reduced especially in the case of serialization of many devices ejection agent.
  • valve body Due to the limited number (here 3) of inputs and outputs (external to the bottle), the valve body can finally be significantly smaller and lighter than bodies such as represented in FIG. figure 1 . It follows that the number of connections or shutters is also greatly reduced: here only the fourth and last valve body (Co4) provides a shutter on its output (Sb4) unused tripping. Assembly and maintenance are therefore much simplified, lighter and faster.
  • the valve body according to the invention comprises a maximum number of inputs and outputs useful for triggering the discharge (and external to the bottle), namely an input and a trigger output of the discharge (Edi, Sbi '), a discharge exit (Sbi).
  • valve body thus proposed according to the invention therefore provides a two-way solution according to the "master / slave" modularity associated with the series arrangements of ejection devices.
  • the valve body according to the invention allows that, from one ejection device to another, the pressure and the flow rate that are useful for triggering are intrinsically regenerated. under excellent conditions at each valve body outlet (Sbi) (master or slave) and at the inlet (Edi + 1) of the next valve body in series, in contrast to the state of the where only the first master valve (V1) is the trigger for all other ejectors, resulting in loss / leakage along a series valve body assembly that may require regeneration (addition of an intermediate pressure redundancy), for example every 20 bottles in the usual cases of current fire extinguishing devices.
  • valve body according to the invention in each of the ejection devices, an unlimited number of ejection devices coupled in series can thus very advantageously be possible, if at least the first or the last ejection device of the ejection device.
  • series includes triggering triggering system (solenoid).
  • the arrangement comprises a plurality N of ejection devices coupled in series: the first and the second valve body (Co1, Co2) thus comprise respectively a solne-noide (Sol, So2) as a discharge initiation device. valves (V1, V2).
  • This redundant configuration of the first and second valve bodies and their solenoids makes it possible to overcome a failure of one of their valves and / or triggers (solenoids).
  • This redundancy is done by fixing the solenoid (So2) on the trigger input of the second valve body from an arrangement according to the figure 1 .
  • the figure 4 has at least one type of valve body according to the invention and arranged under an arrangement of at least two valve bodies (Co1, Co2, ..., CoN), said arrangement according to the invention comprising a priming redundancy .
  • a "master” ejection device and another redundant "master” ejection device can be installed at the beginning and at the end of the series.
  • each valve body is of bivalent geometry in order to be activated by pressure or mechanically.
  • the master and slave valve bodies (Co1, Co2) and their inputs and outputs can thus be geometrically identical and therefore universal.
  • the triggering channel (Cd3) is pressurized further by pressurization due to the branching channel (R2) by means of the bypass channel (D2) extracted from the channel. output (Cs2). Assuming that the first valve (V1) can not be sufficiently primed for a technical reason, this additional pressure may allow it to forced activation.
  • the bypass channel (D2) comprises a nonreturn valve (Car2) in order to maintain the triggering pressure of the "global" triggering channel (Cd1, R1, Cc12, Cd2, R2, Cc23, Cd3, R3, Cc34, Cd4) of all the ejection devices.
  • a device integrated or not integrated with the valve body or with this "global” channel makes it possible to depressurize / withdraw the pressure of this "global” channel ".
  • a trigger channel (Cd2), the branch (R2), the bypass channel (D2), the possible reducers (Red1 and / or Red2) and the non-return valve (Car2) are internal to the first valve body ideally monoblock. The result is a robust and compact valve body.
  • a discharge output (Sd1) of the first valve (V1) is coupled to the trigger input (Ed2) of the second valve body (Co2 ) so as to pressurize the branch channel (R2) as soon as a charge is initiated at the discharge outlet (Sd1) of the first valve (V1).
  • the arrangement according to the invention is adapted so that the valve bodies of the first and second valves and their inputs and outputs are geometrically simply identical / universal.
  • the said arrangement can extend to at least three valve bodies according to the invention respectively comprising one of the valves (V1, V2) and a third valve (V3).
  • Said valve bodies are simply simply coupled in series, in that a connection channel (Cc23) connects under pressure a connection output (Sb2) of the second valve body (V2) to a coupled trigger input (Ed3). a channel (Cd3) for tripping the third valve (V3).
  • the arrangement according to the invention may comprise at least a plurality (N) of valve bodies (Co1, Co2,..., CoN) respectively comprising one of the valves (V1, V2, ..., VN).
