A PRESSURE VALVE |
摘要 |
<p>The invention relates to a pressure valve with a flow passage ( 3 ) having a valve body ( 14 ) and a lifting plate ( 21 ) that has a surface area A<SUB>2 </SUB>transversally of the flow passage ( 3 ) that exceeds the cross sectional area A<SUB>1 </SUB>of the flow passage ( 3 ) at the valve seat ( 13 ) of the valve body, said pressure valve being configured such that, at any time, the container is in communication with the area above the lifting plate ( 21 ). The invention is characterised in that the pressure valve also comprises a magnet ( 8 ) and a magnetisable body ( 9 ); and that the force of attraction F<SUB>m </SUB>between the magnet ( 8 ) and the magnetisable body ( 9 ) and the mass of the lifting plate ( 21 ) contributes to defining the abutment force F<SUB>c</SUB>, of the valve body ( 14 ) against the valve seat ( 13 ) in the closed state of the pressure valve.</p> |
