Pop-up valve

Abstract

A pop-up valve according to an embodiment of the present invention includes a head portion; and a foreign matter catching prevention device that is provided in a lower portion of the head portion, in which the foreign matter catching prevention device includes a body portion that is coupled to a bottom of the head portion; a protruding jaw that is formed radially in an outer circumference of the body portion and whose upper surface is in close contact with the head portion; and a first guide vane that extends downward from a bottom of the protruding jaw so as to be perpendicular to the protruding jaw and is located on one side of a second guide vane of a guide device which is coupled to an inside of a drain pipe.

1 . A pop-up valve comprising:
 a head portion; and   a foreign matter catching prevention device that is provided in a lower portion of the head portion,   wherein the foreign matter catching prevention device includes
 a body portion that is coupled to a bottom of the head portion; 
 a protruding jaw that is formed radially in an outer circumference of the body portion and whose upper surface is in close contact with the head portion; and 
 a first guide vane that extends downward from a bottom of the protruding jaw so as to be perpendicular to the protruding jaw and is located on one side of a second guide vane of a guide device which is coupled to an inside of a drain pipe. 
   
     
     
         2 . The pop-up valve of  claim 1 ,
 wherein the head portion includes
 a main body portion; and 
 a sealing member that is coupled to a lower portion of the main body portion. 
   
     
     
         3 . The pop-up valve of  claim 2 ,
 wherein the sealing member is a packing.   
     
     
         4 . The pop-up valve of  claim 1 ,
 wherein the guide device includes
 a guide main body that is provided with a coupling hole therein; and 
 the second guide vane that is formed radially along an outer circumference of the guide main body, and 
   wherein a compartment space is provided between the second guide vane and the second guide vane.   
     
     
         5 . The pop-up valve of  claim 4 ,
 wherein the first guide vane and the second guide vane are formed in the same number as each other.   
     
     
         6 . The pop-up valve of  claim 4 ,
 wherein the first guide vane and the second guide vane are at least three or more guide vanes, and two of the three or more first guide vanes are located in the same compartment space.   
     
     
         7 . The pop-up valve of  claim 4 ,
 wherein the foreign matter catching prevention device and the guide device are connected by a pop-up rod.   
     
     
         8 . The pop-up valve of  claim 7 ,
 wherein an upper portion of the pop-up rod is connected to the head portion penetrating the foreign matter catching prevention device, and a lower portion is inserted into the coupling hole of the guide main body.   
     
     
         9 . The pop-up valve of  claim 4 ,
 wherein a lower part of the guide main body is a cone whose vertex faces downward.   
     
     
         10 . The pop-up valve of  claim 4 ,
 wherein a lower end of the second guide vane is correspondingly coupled to a catching jaw of a lower portion of an inside of the drain pipe.
