Definitions

  • the invention relates to a valve block according to the preamble of claim 1.
  • each valve unit is placed directly on a front surface of the base body.
  • Each valve unit has a throttle valve on the supply air side and the exhaust air side.
  • the valve body on the inlet side interacts with a control bushing that penetrates the entire main body.
  • the throttle valve on the exhaust air side has a valve body which interacts with a valve seat in the base body. All throttle valve bodies are stored both in the valve housing and in the base body.
  • a pneumatic pilot valve is flanged to an end face of each valve housing. If the valve or the associated pilot valve is damaged, the entire valve unit consisting of the valve and the pilot valve must be dismantled. This and the internal division of the base body are complex and not very flexible.
  • the invention has for its object to simplify and shorten maintenance and assembly work and to allow more flexible use of the valve block.
  • the various mechanisms of a glass molding machine to be controlled are known per se. For example, it can be a preform bottom mechanism. Compressed air is particularly suitable as a flowable medium, but also hydraulic fluid.
  • the valve carrier interposed according to the invention offers several advantages. He is on the with just a few screws Base body attached. By loosening these screws, the valve carrier with all the valve units attached can be removed. As a result, the entire base body for maintenance, programming and, if necessary, repair work is very quickly accessible. The associated glass molding machine can therefore be expected to have very short downtimes.
  • the valve carrier is particularly easy to manufacture.
  • valve units can be quickly removed from the valve carrier and reassembled, and on the other hand, rapid assembly of the valve carrier on the base body is not impeded.
  • the features of claim 4 simplify the medium guidance in the base body and facilitate and accelerate the reprogramming from one medium pressure to the other. After removing the valve carrier, the closure elements are very easy to reach and can be attached quickly in the required distribution.
  • the reprogramming from one medium print to the other is particularly quick and safe.
  • the features of claim 6 offer the particular advantage that a once selected setting of the throttle valves is retained when the valve carrier with all valve units is removed from the base body.
  • an outlet is created from the flange, from which control medium can be removed for another control purpose if required.
  • the electrical connection is automatically interrupted when removing the pilot valve and made when the pilot valve is attached.
  • the electrical lines can be accommodated without additional effort.
  • the design according to claim 13 enables the inexpensive manufacture of the base body.
  • connection openings that are not required can be closed, for example, by a screw plug.
  • the training according to claim 16 causes particularly low manufacturing costs.
  • flowable medium of any pressure can be fed into the base body and thus into the connected valve units.
  • the design according to claim 18 allows the use of the same valves for different tasks without changing the valve carrier, the base body and the connection plate. Changes in the course of the channels can easily be made in the components of the housing.
  • valve block height You also benefit from short distances between the pilot valve and its valve. Another advantage is that each valve and the associated pilot valve can now be assembled and disassembled as a unit from a single side of the valve block.
