Definitions

  • This invention relates to the gasketing of plate heat transfer apparatus.
  • a plate heat transfer apparatus i.e. either a plate heat exchanger or a plate evaporator, consists of a series of plates arranged spaced face-to-face relationship to form flow spaces between the plates. The boundaries of the flow spaces are formed and sealed by gaskets which are normally mounted in grooves pressed into the plates.
  • the gaskets are normally of a rubber or rubber-like material and are retained in their respective grooves by adhesive.
  • the initial mounting of the gaskets in the grooves is a fairly time consuming process involving surface preparation, application of adhesive, location of the gasket in the groove and probably curing of the adhesive. When the gasket needs to be replaced, the old gasket has to be stripped out, the metal surface cleaned of old adhesive and then the new gasket has to be mounted with all that entails.
  • the gasket recesses were precision machined grooves, the sealing could be more easily obtained by using preformed 0-ring, lip or other similar seals which would be a close mechanical fit in the grooves and would therefore not need to be retained by adhesive.
  • metal thickness e.g. 0.7mm
  • precision machining of grooves is not practicable and for many years the use of adhesive has been the normal practice in the industry.
  • a heat .transfer plate having a pressed gasket groove which is at least partially filled with a plastics material which adheres to the plate metal and which is formed with an accurate groove adapted to receive, or receiving, a preformed seal of 0-ring, lip or other appropriate type.
  • a method of forming an accurately profiled gasket recess in a pressed metal plate comprising the steps of forming a pressed recess in the metal plate, at least partially filling the pressed recess with a plastics material which adheres to the metal of the plate, and accurately forming a gasket recess in the plastics material
  • the gasket recess may be formed by moulding or by machining the plastics material.
  • FIG. 1 a heat exchanger plate is illustrated. at 1 and as having four corner ports 2, 3, 4 and 5.
  • the line of a peripheral gasket, of double seal form is indicated at 6, and it will be noted that the corner ports 4 and 5 also have port gaskets 7, also of double seal nature.
  • FIGS 2 to 4 each show a portion of the heat exchanger plate 1 as being provided with a pressed in gasket recess 8.
  • this recess 8 may be converted to a form sufficiently accurate for a preformed seal 6, it is filled with a plastics material 4 which has the property of adhering to the metal of the plate 1 and which is formed, either by pressure moulding or by machining, or a combination of both, with an accurately formed recess 10 to receive the seal.
  • the plastics material may for instance be that sold as 'keebush' or 'keeglass'. These material have the property of adhering to the plate metal, are as flexible as the plate pressing and will withstand attack from a wide range of chemicals over a wide range of temperatures. In addition, these materials are hard and machinable.
  • the plastics material is mixed and positioned in the groove 2 and can be moulded under pressure so as simultaneously to fix it in the rubber groove and to form a suitably profiled recess 10, for the seal.
  • the plastics material can be roughly sculptured and, when cured, machined to form the final shape of the recess 10.
  • Figure 2 shows a construction in which the filling 9 is formed with a pair of such recesses 10, each of which is shown as receiving an 0-ring seal 11 to form the double seal.
  • the configurations of the port gaskets 7 may be similar.
  • a seal of this nature is beneficial, especially if the space between them is monitored for leakage of the hazardous fluid so that this leakge is detected before the hazardous fluid leaks passed the second seal into the ambient atmosphere.
  • the space between the two seals 11 may have an appropriate fluid pumped through it and in circuit with a detector to detect the presence of the hazardous fluid in the diluent. Suitable micro-bore piping may be used to make the connections.
