Definitions

  • the invention relates to a valve battery, with a plurality of electrically actuated control valves, which are each connected to at least one common supply channel and at least one common vent channel and can control the connection of these channels, each with at least one connectable to a consumer individual working channel, with at least one feed channel for feeding pressure medium intended for the at least one common supply channel, and with a safety valve interposed between the at least one feed channel and the at least one common supply channel for selectively enabling or shutting off the channel connection.
  • One from the EP 1 041 325 B1 known valve battery of this type includes a plurality of control modules each equipped with a control module, which are combined to form a module assembly.
  • a common supply channel passing through the module arrangement, all the control valves can be supplied with pressure medium at the same time.
  • the venting of the control valves is done via one or two, the module assembly also passing common venting channels.
  • the common supply channel is preceded by a usable as a safety valve shut-off valve, which is able to shut off the common supply channel of a pressure medium leading in the feed channel, if a Disorder occurs.
  • the valve battery is then decoupled from the print media network. However, if the shut-off process is performed with the valve manifold still under full supply pressure, the pressure medium sealed off in the valve manifold can continue to be the cause of undesirable switching functions of the control valves.
  • valve battery is designed so that the safety valve can be switched to a venting position, in which it vents the at least one common supply channel and at the same time shuts off the feed channel.
  • shut-off time in the at least one common supply channel of the valve battery located pressure medium is not simply trapped, but vented to the atmosphere with shut-off feed channel.
  • the valve battery is therefore depressurized on the supply side, so that even with subsequently occurring switching operations of the control valves in the connected consumers no unwanted functions are triggered.
  • the safety valve can be structurally easily configured so that it automatically switches to the venting position, for example, if a power failure and / or a failure of the supply pressure occurs.
  • valve battery In order to make the valve battery ready for operation as quickly as possible after venting, it can be equipped with at least two feed ducts, which are simultaneously connected in parallel with the common supply duct of the valve manifold in the passage position of the safety valve. The pressure medium can then flow into the valve battery at high flow.
  • the venting of the at least one common supply channel can for example take place exclusively via at least one of the existing at least one common venting channel of the valve battery. In this way, an additional venting channel in the valve battery is unnecessary. If the valve manifold, which is often the case with valve manifolds, contains two common venting channels for the control valves, the safety valve can be designed such that both common venting channels of the valve manifold are used to vent the at least one common supply channel.
  • the safety valve is expediently designed to be electrically activated. It can receive its electrical operating signals individually or via an optionally present in the valve battery standard electrical Verkettungs issued.
  • the safety valve is designed so that it is held in the electrically deactivated state by spring means in the venting position. In order to maintain the passage position, the safety valve is electrically activated and deflected its valve member against the spring force. If the power fails during operation or, in the case of a pilot-operated variant, the pilot pressure, the safety valve is reliably switched back to the harmless venting position reliably by the spring preload.
  • the vent flow passes through a cavity formed in the valve slide of the safety valve. This allows a particularly advantageous channel interconnection.
  • the safety valve can be installed or installed at any suitable point on the valve manifold. In any case, it is on board the valve manifold, so that compact dimensions without external safety components are necessary.

  • the fluid distribution modules preferably each contain two individual working channels connected to the respective associated control valve for controlling a consumer.
  • the fluid distribution module of the safety valve is expediently also penetrated by two individual fluid channels, at least one of which forms a feed channel for the common supply channel.
  • the second fluid channel can be used as a further feed channel connected in parallel or as an additional venting channel. If it is not needed, it can be closed by a stopper if necessary.
