Cooling water scatter preventing type surge tank

Abstract

A cooling water scatter preventing type surge tank assembly, may include a pressure cap, a cap coupling boss, a multi-deformation ring mounted to the pressure cap and selectively engaged to the cap coupling boss to form a receiving space between the pressure cap and the cap coupling boss, wherein the multi-deformation ring may be configured to collect vapor or cooling water discharged through a discharge path opened when a pressure of the vapor or the cooling water rises to an allowable pressure or more, to the receiving space connected to an overflow port

What is claimed is: 
     
         1 . A cooling water scatter preventing type surge tank assembly, comprising:
 a pressure cap;   a cap coupling boss;   a multi-deformation ring mounted to the pressure cap and selectively engaged to the cap coupling boss to form a receiving space between the pressure cap and the cap coupling boss;   wherein the multi-deformation ring is configured to collect vapor or cooling water discharged through a discharge path opened when a pressure of the vapor or the cooling water rises to an allowable pressure or more, to the receiving space connected to an overflow port, to block the receiving space from the outside by the pressure cap, and to be deformed by the pressure cap to perform sealing processing on the receiving space double.   
     
     
         2 . The cooling water scatter preventing type surge tank assembly of  claim 1 , wherein the multi-deformation ring is deformed by a fastening force of the pressure cap with the receiving space in a state in which an end of the multi-deformation ring is inserted into the pressure cap to perform the sealing processing on the receiving space double. 
     
     
         3 . The cooling water scatter preventing type surge tank assembly of  claim 2 , wherein the end of the multi-deformation ring is fitted in a ring groove which is formed in the pressure cap. 
     
     
         4 . The cooling water scatter preventing type surge tank assembly of  claim 3 ,
 wherein the pressure cap is provided with a concentric flange in which the ring groove is formed to be assembled with the multi-deformation ring,   wherein the concentric flange is disposed concentrically on a pressure cap body of the pressure cap which is fastened with a filler neck protruding from the cap coupling boss in the receiving space communicating with an inside of a surge tank, and   wherein the pressure cap body is provided with a gasket which selectively contacts a top surface of the filler neck.   
     
     
         5 . The cooling water scatter preventing type surge tank assembly of  claim 1 , wherein the multi-deformation ring is made of a plate rubber material. 
     
     
         6 . The cooling water scatter preventing type surge tank assembly of  claim 5 , wherein the multi-deformation ring includes:
 a circular body having an annular ring shape and configured to be coupled to the pressure cap; and   a deformation protrusion and a deformation wing which are integrally formed at an outer edge of the circular body, and   wherein the deformation wing and the deformation protrusion each seal the receiving space by contacting an outer wall of the cap coupling boss to perform the sealing processing on the receiving space double,   wherein the receiving space is enclosed by the outer wall of the cap coupling boss and the pressure cap.   
     
     
         7 . The cooling water scatter preventing type surge tank assembly of  claim 6 , wherein the deformation wing protrudes outside of an outer edge of the circular body in a horizontal section of the circular body and the deformation protrusion protrudes downward from the deformation wing. 
     
     
         8 . The cooling water scatter preventing type surge tank assembly of  claim 7 , wherein the deformation protrusion and the deformation ring each have a triangular shape. 
     
     
         9 . The cooling water scatter preventing type surge tank assembly of  claim 1 ,
 wherein the receiving space communicating with the inside of a surge tank is formed between a filler neck and an outer wall, the filler neck being formed to protrude from the cap coupling boss and configured to be fastened with the pressure cap along with a gasket, and the outer wall protruding from the cap coupling boss to enclose the filler neck in a concentric circle to form the receiving space therebetween.   
     
     
         10 . The cooling water scatter preventing type surge tank assembly of  claim 9 , wherein the outer wall, the filler neck, and the receiving space are formed as a space in which the cooling water is expanded, in the surge tank. 
     
     
         11 . The cooling water scatter preventing type surge tank assembly of  claim 9 , wherein an inner peripheral surface of the pressure cap is provided with a female screw and an outer peripheral surface of the filler neck is provided with a male screw such that the pressure cap is configured to be selectively engaged with the filler neck.
