[발명의 분야][Field of Invention]

본 발명은 냉수 및 온수를 동시에 공급할 수 있는 쌍급수밸브에 관한 것이다.The present invention relates to a double water supply valve capable of supplying cold water and hot water at the same time.

구체적으로 본 발명은 급수구로 유출되는 수압을 감압시키기 위한 감압수단이 구성된 쌍급수밸브에 관한 것이다.Specifically, the present invention relates to a double water supply valve configured with a pressure reducing means for reducing the water pressure flowing into the water supply port.

[발명의 배경][Background of invention]

온수와 냉수를 동시에 사용하려면 쌍급수밸브를 사용해야 한다. 종래의 쌍급수밸브는 쌍급수밸브를 구성하는 각각의 급수밸브의 출수관을 T자형의 급수관으로 연결시킨 것이다. 상기와 같이 하여 쌍급수밸브를 구성시키면, 온수, 냉수 또는 온수와 냉수를 동시에 공급하여 적당한 온도의 온수를 만들어 사용할 수 있다. 이와 같은 쌍급수밸브에 공급되는 물의 수압은 3∼15㎏/㎠정도이다. 쌍급수밸브에 공급되는 물의 수압이 높으므로 유출되는 물의 수압도 높다. 일례로 상기 쌍급수밸브를 세탁기에 사용하면 유출구 끝단에서 맴돌이 현상이 발생하는 문제점이 있었다. 또한 쌍급수밸브의 입수부에 물이 유입되지 않아 수압이 안걸려 있는 경우 유출관으로부터 거꾸로 쌍급수밸브 입수부쪽으로 물이 역류되는 문제점도 있었다.To use both hot and cold water simultaneously, you must use a double feed valve. In the conventional double water supply valve, a water supply pipe of each water supply valve constituting the double water supply valve is connected to a T-shaped water supply pipe. When the dual water supply valve is configured as described above, hot water, cold water or hot water and cold water may be supplied at the same time to make and use hot water at an appropriate temperature. The water pressure of the water supplied to the dual water supply valve is about 3-15 kg / cm 2. Since the water pressure of the water supplied to the double feed valve is high, the water pressure of the water flowing out is also high. For example, when the double water supply valve is used in a washing machine, a eddy phenomenon occurs at an outlet end. In addition, when the water pressure is not applied to the inlet portion of the double water supply valve, there is a problem in that water flows backward from the outlet pipe to the inlet portion of the double water supply valve.

[발명의 목적][Purpose of invention]

본 발명의 목적은 쌍급수밸브의 입수구로 유입된 물의 압력을 감압시켜 급수구로 유출시키는 감압수단이 구성된 쌍급수밸브를 제공하는 것이다.It is an object of the present invention to provide a double water supply valve having a decompression means configured to reduce the pressure of water introduced into the inlet of the double water supply valve and discharge it to the water supply port.

본 발명의 다른 목적은 쌍급수밸브의 급수구로 유출되는 물에서 맴돌이 현상이 일어나지 않도록 감압수단이 구성된 쌍급수밸브를 제공하는 것이다.Another object of the present invention is to provide a double water supply valve configured with a decompression means so that no eddy phenomenon occurs in the water flowing into the water supply port of the double water supply valve.

본 발명의 또 다른 목적은 쌍급수밸브의 급수구로부터 입수구쪽으로 물이 역류하지 않도록 감압수단이 구성된 쌍급수밸브를 제공하는 것이다.Still another object of the present invention is to provide a double water supply valve configured with a decompression means such that water does not flow back from the water supply port of the dual water supply valve toward the inlet port.

[발명의 구체예에 대한 설명][Description of Specific Example of the Invention]

이하 본 발명을 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 종래의 쌍급수밸브의 사시도이다. 종래의 쌍급수밸브는 좌우양쪽에 있는 온수급수밸브(1) 및 냉수급수밸브(2)의 출수관(3)을 T자형의 급수관(4)으로 연결하여 구성한다.1 is a perspective view of a conventional double water supply valve. The conventional double water supply valve is configured by connecting the water supply pipe 3 of the hot water supply valve 1 and the cold water supply valve 2 on both the right and left sides with a T-shaped water supply pipe 4.

본 발명의 감압수단이 구성된 쌍급수밸브를 제2도 및 제3도로 참고로 상세히 설명한다.The dual water supply valve configured with the pressure reducing means of the present invention will be described in detail with reference to FIGS. 2 and 3.

온수급수밸브(10) 및 냉수급수밸브(11)의 출수관(12,13)은 각각 플렉시블튜브(14)에 삽입되어 있다.The outlet pipes 12 and 13 of the hot water feed valve 10 and the cold water feed valve 11 are inserted into the flexible tube 14, respectively.

플렉시블튜브(14)는 온수급수밸브의 출수관(12) 및 냉수급수밸브의 출수관(13)을 각각 급수구하우징의 하부에 원통형으로 돌출된 유입구(16,17)에 각각 연결시킨다.The flexible tube 14 connects the outlet pipe 12 of the hot water feed valve and the outlet pipe 13 of the cold water feed valve to the inlets 16 and 17 protruding in a cylindrical shape from the lower portion of the water inlet housing, respectively.

급수구하우징(15)은 좌우양쪽벽 후면에 원통형이며 끝에 돌기가 형성된 유입구(16,17)가 각각 형성되어 있으며 전면쪽에는 급수구(18)가 형성되어 있다.The water inlet housing 15 has cylindrical inlets on both the left and right rear walls, and inlets 16 and 17 having protrusions formed at the end thereof, respectively, and a water inlet 18 is formed at the front side thereof.

차단벽(19)은 얇은 판모양으로 급수구하우징 내부에서 급수구하우징의 상하부 및 바닥벽과 일체로 형성되며 급수구하우징 내부공간을 둘로 분할한다. 또한 차단벽은 냉수가 통하는 공간이 온수가 통과하는 공간보다 크도록 한쪽으로 치우쳐서 구성된다.The barrier wall 19 has a thin plate shape and is integrally formed with the upper and lower portions of the water inlet housing and the bottom wall in the water inlet housing, and divides the internal space of the water inlet housing into two. In addition, the barrier wall is configured to be biased to one side so that the space where the cold water flows is larger than the space where the hot water passes.

지지핀(20)은 막대형상이며 한쪽단이 급수구하우징 내부바닥과 일체로 형성되며 다른쪽단은 급수구(18)쪽으로 돌출된다.The support pin 20 is rod-shaped and one end is integrally formed with the inner bottom of the water inlet housing, and the other end protrudes toward the water inlet 18.

감압재(21)는 다공성의 폴리우레탄 스폰지로 제작되며 급수구하우징 내부공간을 채우고 있다.The pressure sensitive material 21 is made of a porous polyurethane sponge and fills the internal space of the water inlet housing.

급수구(18)로부터 온수급수밸브의 입수관(22)과 냉수급수밸브의 입수관(23)쪽으로 물이 역류되는 것을 방지하고 플렉시블튜브(14)에 물이 남아 있는 것을 방지하기 위해 출수관(12,13)과 유입구(16,17)사이에 3㎜이상의 단차(x)를 둔다.In order to prevent water from flowing back from the water inlet port 18 to the inlet pipe 22 of the hot water feed valve and the inlet pipe 23 of the cold water feed valve, and to prevent water from remaining in the flexible tube 14, There is a step (x) of 3 mm or more between 12, 13 and inlets 16, 17.

본 발명의 작용 및 효과는 다음과 같다. 강한 수압의 물이 유입구(16,17)로 급수될 경우 유입된 물은 제3도의 화살표로 표시된 경로를 따라 흐르게 된다. 유입된 물은 막대형상의 지지핀(20)에 부딪치어 수압이 감소되어 이 수압이 감소된 물은 다공성 폴리우레탄 스폰지로 제작된 감압재(21)의 미세구멍을 거쳐나오면서 재차 수입이 감소된다. 감압되어 급수구(18)로 배출되는 물은 급수구(18)에서 유입구(16,17) 방향으로 물이 유입될시 지지핀(20) 및 감압재(21)에 의해 수압이 감소되므로 물이 역류되지 않는다.Effects and effects of the present invention are as follows. When water of high pressure is supplied to the inlets 16 and 17, the inflowed water flows along the path indicated by the arrow of FIG. 3. The introduced water hits the rod-shaped support pin 20 and the water pressure is reduced so that the water is reduced again while passing through the micropores of the pressure-sensitive material 21 made of the porous polyurethane sponge. When the water is decompressed and discharged into the water inlet 18, the water pressure is reduced by the support pin 20 and the pressure reducing material 21 when water is introduced from the water inlet 18 toward the inlets 16 and 17. No backflow
