Definitions

  • retrievers For performing replacement of probes are previously known so called retrievers, for example hydraulic retrievers referred to in NO-patent 162832 and NO-patent 174942.
  • the use of hydraulic and/or mechanic retrievers involves a large cost saving, as the probes can be installed, respectively removed, without altering the process.
  • this known method will involve a leakage risk.
  • the valve could be opened comparatively easily by accident. This can have great consequences, as the process medium may leak to the environments. It is therefore an object with present invention to provide a device of the above mention kind, which represent an increased safety compared to today's equipment.
  • the object of the invention is achieved by a device having features as stated in the characterizing part of claim 1. Further features are stated in the dependent claims. The invention will now be described more in detail by means of an example of embodiment and with referance to the enclosed drawing, showing a device according to present invention, partly in section.
  • valve unit 1 comprising a lower valve body 2 and an upper valve body 3.
  • Lower valve body 2 contains a lower valve ball 5 with associated lower valve seats 6.
  • the upper valve body 3 contain an upper valve ball 7 and associated upper valve seats 8.
  • Above upper valve body 3 is located an end section 4 which is fasten by means of fasten pins 9.
  • a not shown retriever of mechanical, hydraulic or other type is adapted to be installed to the end section 4.
  • Between lower ball 5 and upper ball 7 is located a lower pressure equalizing valve 10.
  • an upper pressure equalizing valve 11 I order to control closure of lower, respectively upper valve ball 5, 7, a lower valve handle 12, respectively an upper valve handle 13 are provided.
  • the handles 12, 13 can be replaced by automatical control means.
