Definitions

  • valve disc 7 of the first valve unit 5 will reach its valve seat l1 a little before the valve disc 8 of the second valve unit 6 reaches its valve seat 12, which means that the spring 29 will be compressed somewhat.
  • valve discs 7 and 8 When the valve discs 7 and 8 are in contact with their seats 11 and 12 respectively, the equipment has assumed its dishwashing and/or sterilizng position, which 'means that inflow of the sterile goods to be packaged is shut ofi ⁇ and also that the washing and/or sterilizing agent is at the same time admitted into the valve from the pipe 4 through the opening 34, and also that there is formed a sealed and distinct space 13 mainly between the valve discs 7 and 8.
  • valve discs 7 and 8 assumed their positions in the washing and/or sterilizng position of the equipment, the sealing rings 23, 24, 25 and 26, fitted on the valve spindles 9 and 10, also assumed positions such that the passages 17, 41, 19 and 40 as well as the ducts 18, 15 and 20 have become separated in such a way that passages to and.
  • the flushing agent which in the present case is superheated steam, is admitted to the system through the supply pipe 21.
  • the steam is thereafter transported to the space 13 through the passage 17 which is delimited by the sealing ring 26 and a sealing ring 28 fitted in the valve housing 1, and then Ato the duct in the inner valve spindle 9 through the duct 18 and the passage 4l which is delimited by the sealing rings 24 and 25.
  • the exit route of the steam from the space 13 consists of the passage 19, one end of which is connected to the space 13 and the other end is delimited by the sealing rings 24, the duct 20 and the passage 40 which is delimited by the sealing ring 26 and a sealing ring 27 fitted in the valve housing 1.
  • the piston motor unit 3l presses onto the valve spindle 10 through the circlip 33, so that seal between the valve disc 8 and the valve seat l2 is ensured.
  • the seal between the valve disc 7 and the valve seat ll is guaranteed by two independent forces, namely the spring force and the steam pressure in the space 13.
  • the steam has another duty in the space 13, namely to flush and sterilize this space.
  • valve in the equipment in the washing and/or sterilizng position shown, satisfies the minimum requirement that can be specified, namely that there should always be at least two seals between the goods to be packaged and e.g., a dishwashing agent, and that the space between the seals should be flushed by a cleansing agent, which agent in the present case consists of superheated steam which is capable of cleansing and sterilizng the said space.
  • a cleansing agent which agent in the present case consists of superheated steam which is capable of cleansing and sterilizng the said space.
  • the piston motor exerts a pull in the other direction,whereupon the circlip 33 moves away from the valve spindle 10, as a result of which the pressure of the valve disc 8 on the seat l2 eases and at the same time the spring pressure on the valve disc 7 decreases. Since the circlip 33 is in engagement with the inner valve spindle 9, the valve disc 7 and, via the spring, the valve disc 8 as well, is drawn down towards the valve seat 35-see FIG. 2-in order to seal off the passage 34 and at the same time open the valve to admit and allow flow of the sterile goods through the valve.
  • the piston motor will continue to pull downwards the inner valve spindle 9 even after the valve disc 8 has come in contact with the valve seat 35, until such time as the valve disc 7 forms a seal around the top 36 of the valve disc 8.
  • the spring 29 will be compressed and that the seal of the valve disc 8 with the valve seat 35 is guaranteed during this so-called filling position, both as a result of the fact that, all the time that the equipment is in this position, the piston motor maintains its pressure on the inner valve spindle 9 which forces the valve disc 8 down onto the valve seat 35 via thevalve disc 7, and also as a result of the compressed spring 29 exerting pressure.
  • the equipment described and illustrated is capable of utilization in fields other than the sterile packaging industry, for instance in chemical engineering. It will vbe evident that this equipmentis especially useful in all piping systems where different substances are to be transmitted through the system at different times, i.e., where the various substances are to be separated. This is particularly the case where the substances are kept in adjacent spaces. lt must be pointed out once again that, despite its simple construction and operation, the valve has the particularly advantageous property of being capable of separating different substances by means of a double seal, and of offering the possibility at the same time of the space between the seals being flushed with a cleansing, dishwashing or sterilizng agent. These agents may naturally be substances other than steam. The agent to be used is dependent on the purpose for which the equipment is to be used, but a chemical catalyst or reagent may be quoted as examples.
  • valve housing and valve units are also dependent on the purpose for which the equipment is to be used, but in the preferred constructional version, the valve housing should preferably be made of acidand corrosion-resistant material, but such material that will not contaminate the foodstu' in question.
  • a valve structure for controlling the flow of a first liquid through a pipe and for controlling the flow of a cleaning fluid through the pipe when the first liquid is stopped comprising, a pipe, a first valve f'or controlling the flow of the rst liquid into said pipe, a second double-acting valve for controlling the flow of the cleaning fluid into said pipe, said second valve when open to the cleaning liquid being closed to the first liquid to supplement the closure of said first valve in serial dispositionv therewith, means for actuating said first and second valves whereby when said first valve is open said second valve is open to the first liquid and is closed to the cleaning liquid and when said first valve is closed to the first liquid said second valve is open to the cleaning liquid, said first valve and said second valve forming a space therebetween in the latter valving position which is sealed from said pipe and the cleaning fluid and means for flushing said space with a flushing agent.
  • valve actuating means comprises concentric valve spindles, the inner spindle actuating said first valve and the outer spindle actuating said second valve.
  • valve structure as claimed in claim 2 wherein said valve actuating means further comprises means for relatively displacing said concentric valve spindles.
  • a valve structure as claimed in claim l wherein said first valve when open to the first liquid is in sealed engagement with the second valve when it is seated to close off the cleaning liquid.
