Definitions

  • the invention relates to an expansion tank structure used in the water heating systems.
  • the invention particularly; relates to an expansion tank structure used in the adjustment of the pressure in water heating systems with boiler and similar area.
  • Expansion tank (expansion vessel), boiler, combi boiler, central systems are used in order to prevent the damage of the pipe and mechanical parts in the system due to the increase in the hot water volume which is heated. If you are using a boiler in order to heat your home or office, there is water in the honeycomb radiator and the device as part of the heating system. In boilers, there is no need for another external expansion tank as in the other boiler and central systems. While the boilers are produced, they are sold with the expansion tank on them. When there is no water expansion tank in our system or if it is out of order, there will be an increase in the compression pressure in the pipes in other words, the water pressure level will increase and will leak from the weakest point. The expansion tank serves to collect the excess water which is heated here.
  • rubber material is used within the expansion tanks.
  • the raw material mixture of the rubber material has high cost.
  • the expansion tanks leaves effects such as odour stain etc. during the production of the membrane.
  • the rubber used has a negative impact on human health.
  • the invention aims to solve the abovementioned disadvantages by being inspired from the current conditions.
  • the main aim of the invention is to provide an expansion tank which is durable and easy to manufacture. Since the diaphragm is made of polypropylene (PP) material, it will be more durable than the ones made of rubber material. Ease of production and assembly is provided with the developed sealing gasket.
  • PP polypropylene
  • Another aim of the invention is to provide cost advantage and at the same time to leave a healthier effect in the work environment of the producer. Also, the aim is to have a durable and/or stable structure by increasing the strength of the expansion tank structure and to decrease the costs.
  • the invention is an expansion tank structure used in the adjustment of the pressure in water heating systems with boiler and similar area, it comprises a polypropylene diaphragm which provides the pressure adjustment of the installation by dividing the internal volume of the expansion tank structure into two sections which is formed by interlocking of the upper cover and lower cover sheets to each other with the help of the cord, is produced with the injection system, a sealing gasket which protects the pressure created by the gas filled in the expansion tank with the valve by connecting it to the expansion tank diaphragm consisting of two parts.
  • Figure 1 is the unpressurized sectional view of inventive expansion tank.
  • Figure 2 is the pressurized sectional view of inventive expansion tank. Description of the Part References
  • the expansion tank structure (1 ) is used for absorbing the excess pressure caused by heating of the installation fluid in closed systems.
  • the expansion tank structure (1 ) is formed by means of interconnecting the upper cover (2) and the lower cover (3) sheets to each other with the help of the cord (4).
  • the internal volume of the expansion tank structure (1 ) is divided into two with the diaphragm (5) made of preferably the injection system and polypropylene and sealing gasket (8) included in the expansion tank structure (1 ). Gas with required pressure is filled into a region of the internal chambers with the help of the valve (6).
  • the diaphragm (5) is pushed towards the lower cover (3) by this filled gas pressure, thus the majority of the internal volume is covered with the gas.
  • the system is operated by connecting an expansion tank to a closed system hot water or heating installation.
  • the pressure of the liquid in the heating installation starts to increase since the volume is constant in closed systems.
  • the threaded pipe (7) provides the entrance of the pressure of the installation into the expansion tank structure (1 ).
  • the pressure of the installation starts to be more than the gas pressure compressed into the gas zone
  • the pressure of the installation starts to fill inside through the threaded pipe (7) by the installation connection pipe and gains additional volume by pushing the diaphragm (5) which separates the expansion tank structure (1 ) towards the upper cover (2).
  • the pressure of the installation is balanced by means of this additional volume which is gained in the installation.
  • the temperature of the liquid in the system decreases and the pressure also decreases proportionally.
  • the diaphragm (5) starts to descend towards the lower cover (3) again.
  • the diaphragm (5) returns to its original position.
  • the expansion tank structures (1 ) included in the closed systems repeat itself during the whole period when there is heating in the system.
  • the diaphragm (5) is preferably made of double part and/or single part structured polypropylene which increases durability. As a result of these repetitions, in order not to lose the gas and its pressure, the operation life of the expansion tank structure (1 ) is extended with the double part and single part structured diaphragm (5) and sealing gasket (8).
