Definitions

  • Pressure relief valves which are also referred to as pressure relief valves, to be installed. Open relief valves as soon as a set / predetermined pressure is reached or exceeded, to prevent further increase in pressure, for example in a tank, a hydraulic line or in a hydraulic system.

  • the tightness of the inventive pressure valve is characterized in that the valve member is formed as a truncated cone or a dome, easier to reach.
  • the reliability of the pressure valve according to the invention is increased and that of the leaf spring
  • Valve seat can be significantly reduced.
  • thermoplastic material preferably made of a thermoplastic material

  • valve member at one end of the leaf spring. Then, the other end of the leaf spring is inserted into a receptacle in a housing or a counterpart and the assembly is done.
  • the receptacle must be designed so that it firstly brings the arranged at the other end of the leaf spring valve member to coincide with the valve seat on the counterpart. Second, it must absorb the required bending moment, so that the leaf spring, the valve member with the desired contact pressure pressed against the valve seat.
  • the Anpressdru8ck is an important parameter in the constructive determination of the opening pressure of the pressure valve according to the invention.
  • the leaf spring is formed at least at one end as a snap connection.

  • Valve seat carries, has two complementary hooks, so that by simply sliding the leaf spring or Das
  • the leaf spring has an opening at one end and a hook at the opposite end. Then, the leaf spring according to the invention with the molded valve member can be said to act like a "belly band" around a tube which carries the valve seat, be bolted and locked by snapping the hook into the breakthrough. Even then the assembly has already taken place. Tools are not required.
  • the leaf spring has at one end a channel with a resilient snap hook and at the opposite end a plurality of sawtooth-like recesses or projections.
  • Snap connection is more or less tightened until the desired opening pressure is set.
