Definitions

  • the invention relates to a temperature sensor with glass vial release, whereby the glass vial is arranged in a body screwed onto a control line or the like with a free space, side openings and control bore and is supported under pressure.
  • Such temperature sensors are used in extinguishing systems with a gaseous extinguishing medium and open extinguishing nozzles.
  • the glass barrel bursts in such a way that, due to the pressure drop in the control medium, the area valve or valves for the extinguishing medium are opened
  • Such temperature sensors are also used to actuate heat or smoke flaps in the ceilings of buildings, in order to avoid the build-up of heat.
  • the glass vials were installed in the temperature sensor using a plate spring and locked with pinning using a double torque.
  • appropriate seals are required. These seals give way after the torque is applied. For this reason, after a first application of torque after max. The attachment is loosened again for 2 hours and the glass barrel is pressed on with a second torque. To prevent the resulting pre-tension from being changed, the glass barrel attachment was secured with an additional safety pin.
  • Such a configuration of a temperature sensor is not only complex and expensive to manufacture but also complex to assemble. There is also the risk that the glass vials will be destroyed if the torque is too high.
  • the invention has for its object to avoid the disadvantages of the previous temperature sensors and at the same time to simplify the assembly.
  • control bore is a piston acted upon by a pressurized control gas or quenching gas, which presses with a seat against the glass barrel.
  • the glass barrel With the piston loosely seated in the control line, the glass barrel can be easily inserted through the control hole into the body of the temperature sensor and is only locked in place by means of a pressurized piston.
  • Glass vials with a small outside diameter are preferably used, so that the vial can be inserted into the free space from below through the control bore.
  • the body of the temperature sensor must be made in two parts.
  • the body consists of an upper body part with an internal thread in the lower part and a lower body part with an external thread in the upper part, these two parts being screwed into one body.
  • the piston is provided with a groove for receiving an O-ring.
  • This O-ring not only provides a seal so that neither control gas nor the extinguishing gas can escape, it also serves as an assembly aid because, after inserting the glass barrel, it locks it so far that it does not fall down before being exposed to the compressed gas.
  • the body 1 is provided with a control bore 2, which ends in the lower part in a thread 3 for attachment to a control line or the like and on the other hand opens into a free space 5 for receiving a glass barrel 13.
  • the free space 5 is laterally provided with openings 6 and 7, so that the glass vial can be subjected to heat if necessary.
  • a seal 4 is located above the thread 3, so that there is a tight screw connection to the control line.
  • the body 1 is provided with a further bore 8 and a seal 9, into which the tip of the glass barrel 13 extends.
  • the outer diameter of the glass vial 13 is smaller, ie the diameter of the control bore 2, so that the glass vial can be inserted into the body from below.
  • the body 1 is made in two parts and, according to FIG. 2, consists of an upper body part 14 with an internal thread 16 in the lower part and a lower body part 15 an external thread 17 in the upper part. Both parts are then screwed into a body 1. All other parts correspond to the parts according to FIG. 1.
  • a locking body which is made of plastic or is designed as a spring, can be inserted into the control bore 2 to secure it in transit and as an assembly aid.
