Device for Controlling Flow Rate

Abstract

A device for controlling the flow rate of flowable products, in particular of foodstuffs, comprising: a valve rod, a sealing element with at least one sealing lip connected to the valve rod, wherein the sealing element comprises a base plane and a contact plane, wherein the sealing lip is arranged on the contact plane and an outlet element with a stop plane and with at least one outlet channel, wherein the stop plane has at least one sealing region assigned to the sealing lip and at least one outlet region connected to the outlet channel. The contact plane is spaced apart from the base plane, so that an offset is created between the sealing lip and the base plane.

         19 . The device according to  claim 16 , wherein the valve rod is made of at least one of plastic and metal. 
     
     
         20 . The device according to  claim 16 , wherein the outlet element is made of at least one of plastic and metal. 
     
     
         21 . The device according to  claim 16 , wherein the sealing element has a stiffening element made of metal. 
     
     
         22 . The device according to  claim 16 , wherein an intermediate element is arranged between the valve rod and the sealing element and connects the valve rod to the sealing element. 
     
     
         23 . The device according to  claim 22 , wherein the intermediate element comprises two opposite threads, wherein one thread is assigned to the valve rod and wherein the other thread is assigned to the sealing element. 
     
     
         24 . The device according to  claim 22 , wherein the intermediate element comprises a threaded bolt and a spacer element. 
     
     
         25 . The device according to  claim 22 , wherein the intermediate element is sealed on both sides with an O-ring, in particular with a coated O-ring. 
     
     
         26 . The device according to  claim 16 , further comprising a pressure plate which is arranged between the sealing element and the valve rod, in particular between the sealing element and the intermediate element. 
     
     
         27 . The device according to  claim 16 , wherein the sealing regions and the outlet regions are arranged on a common plane. 
     
     
         28 . A use of a device according to  claim 16  for filling foodstuffs, in articular for the aseptic filling of foodstuffs.
