Definitions

  • the invention relates to a valve arrangement, with a valve carrier and at least one electrically actuated valve unit, wherein the valve unit has a main valve means and a serving for actuating the main valve means, electrically actuable pilot valve means and encapsulated housed in an outwardly closed receiving space of the valve carrier, which limits together is of a main body of the valve carrier having valve carrier channels connected to the main valve means, and of a releasably attached to the base cap of the valve carrier.
  • A1 known valve assembly of this type has a modular valve carrier with a plurality of valve carrier modules, each defining a receiving space in which an electro-fluidically pilot-operated valve unit is housed.
  • the receiving space is jointly bounded by a base body and by a cover attached to the base of the valve carrier, wherein the valve unit is seated entirely in the interior of the body. Since the removal of the valve unit from the main body is problematic due to the limited accessibility, the valve unit is fixed to the base body by means of fixing screws which are supported on the closure lid and become common in the event of an exchange removed with the cap from the body. This complicates the handling in a possibly necessary replacement of the valve unit.
  • valve assembly At one of the EP 1 120 574 B1 known valve assembly are unconfined individual valve units mounted on a base body of a valve carrier and individually enclosed by hood-like covers. The entire valve unit is housed in the hood-like cover. The assembly and disassembly with respect to the body takes place at each valve unit together with the associated cover. Due to the relatively high height of the covers, gaps between adjacent covers are difficult to access for cleaning.
  • the invention has for its object to provide a valve assembly that is particularly easy to assemble and clean with a simple and inexpensive construction.
  • the invention provides that the closure lid is hood-shaped with a top wall and a laterally circumferential peripheral wall and the receiving space consists of a formed in the base body lower space portion and an upper lid portion formed in the cap, said valve unit having a lower portion, containing at least a portion of the main valve means is received in the lower space portion and fixed independently of the closure lid on the base body and wherein the valve unit protrudes with a protruding from the base upper portion in the upper space portion and is enclosed at the top and side of the closure lid.
  • valve unit is housed partly in the base body and partly in the hood-like closure lid of the valve carrier.
  • the valve unit protrudes piece-wise out of the body and can be gripped comfortably and without special aids at its upper portion during its assembly or disassembly.
  • a participation of the closure cap in the attachment of the valve unit is therefore not required.
  • the valve unit is received in the base body with part of its overall height, however, it protrudes only to a limited extent out of the main body, so that only a relatively small structural height is required for the hood-like closure cover surrounding it above. This favors the lateral accessibility of the closure cap for cleaning purposes, when the valve carrier is installed close to a wall or when the valve carrier is provided with a plurality of juxtaposed closure covers, each covering a valve unit in the upper region.
  • the height of the two formed in the base body and in the closure cover space sections is matched to the height of the valve unit that at least the main valve means of the valve unit and preferably also the pilot valve means with at least 20%, but not more than 80% of their height in the body formed in the lower body portion recorded in the recording room. Only the remaining height portion of the main valve device and possibly the pilot valve device protrudes from the base body.
  • the valve unit is designed so that both its main valve device and its pilot valve device is partially seated in the main body and partially in the receiving space.
  • pilot valve device is equipped with one or more solenoid valves designed as pilot valves, it is advantageous if the designed as an electromagnet drive component of the pilot valve is housed entirely in the formed in the base body lower space portion of the receiving space.
  • valve unit In order to fix the valve unit to the base body, expediently only those fastening means are used which are only accessible from the outside when the closure cover has been removed.
  • the valve unit When installing a valve unit, therefore, the valve unit is first inserted into the base body and fastened therein, before subsequently the closure lid is attached and in turn fastened.
  • valve unit By independent of the cap attachment of the valve unit on the body can be ensured that the valve unit, especially during maintenance, even with the cap removed fully functional. Whether the closure lid is attached or not, affects the operability of the valve body attached to the base unit as such expediently not.
  • the formed in the base body lower space portion of the receiving space is formed pocket-like and is bounded both on the opposite side of the closure lid bottom and around the side of the base body. In this way, no additional components are needed to prevent contamination from entering the bottom Prevent space section. If the receiving spaces are accommodated in individual valve carrier modules of the valve carrier, the lower space section is limited laterally all around directly exclusively by the preferably integral body of the respective valve carrier module, so that the adjacent valve carrier module is not required to form a wall portion of the receiving space.
  • the joining region between the closure lid and the base body is sealed by an annular sealing means which is clamped between the end face of the peripheral wall of the closure lid and a sealing surface of the base body framing the opening of the lower space portion.
  • This sealing means is expediently designed exclusively for sealing between the closure lid and the base body and has no sealing function with regard to any other components of the valve arrangement which may be present.
  • this sealing means is preferably not used in order to effect an additional seal between adjacent valve carrier modules in a modular construction of the valve carrier.
