Abstract

PURPOSE: A check valve of Freon gas for refrigerant is provided to control fluid to flow slack in streamline by a buffed protrusion, and to allow large amount of fluid to flow without resistance. CONSTITUTION: A spring(130) has one end inserted into a protrusion(140) formed on one side of a check valve(100), and the other end allowing a screw protrusion(120) to be inserted thereto. Fluid is introduced into a tube(110), and flows in streamline due to the semi-circular screw protrusion. The screw protrusion is placed around an inlet of the tube, and is pushed by introduced fluid. The streamlined screw protrusion is pushed back by introduced fluid and slows down flow of fluid to control flow rate of fluid. The spring is inserted to the screw protrusion, and controls movement of the screw protrusion. A rectangular shape is formed integrally with the protrusion part, and penetrate wide to allow fluid to be discharged without loss. The protrusion part secures a channel for fluid easily more than an existing opening and closing wing, and generates less resistance to allow fluid to freely move.

Description

냉매용 프레온가스의 체크밸브{check valve in fraon gas for refrigerant}Check valve in fraon gas for refrigerant

본 발명은 냉매용 프레온가스의 체크밸브에 관한 것으로, 특히 원형돌기를 거치게 하여 유체를 원활하게 흐를 수 있도록 한 냉매용 프레온가스의 체크밸브에관한 것이다.The present invention relates to a check valve of a refrigerant freon gas, and more particularly, to a check valve of a refrigerant freon gas that allows a fluid to flow smoothly through a circular projection.

일반적으로, 유체가 흐르는 배관내에는 유체가 정방향으로 흐르도록 하고 역방향으로 유체가 흐르는것을 방지하기 위해 체크밸브(check valve)를 사용한다. 이러한 체크밸브의는 상기한 바와같이 유체가 역류되는것을 방지하기 위해 사용되며, 통상적으로 체크밸브 단독으로 사용하기 보다는 동일 배관 라인상에 메인 개폐밸브(main openclose valve)와 드래인 밸브(drain valve)등 다른 밸브(valve)와 혼용 설치되어 사용된다.In general, a check valve is used to allow the fluid to flow in the forward direction and to prevent the fluid from flowing in the reverse direction. These check valves are used to prevent backflow of fluid as described above, and are generally used as main openclose valves and drain valves on the same piping line rather than as a check valve alone. It is used in combination with other valves.

도 1 은 종래의 체크밸브의 사시도이고, 도 2 는 종래의 체크밸브의 단면도로서, 이를 참조하여 설명하면 다음과 같다.1 is a perspective view of a conventional check valve, Figure 2 is a cross-sectional view of a conventional check valve, as described with reference to the following.

배관(11) 내부에 너트(12)가 형성되고, 형성된 너트(12) 중단부에 개폐날개(13)가 고정,밀착된다.A nut 12 is formed in the pipe 11, and the opening / closing wing 13 is fixed and tightly attached to the stop portion of the formed nut 12.

상기 개페날개(13)와 일체가 된 돌기부에 스프링(14)를 삽입하고, 원형돌기(15)를 밀면 개폐날개(13) 중앙에 형성된 홀에 돌기가 삽입된다.The spring 14 is inserted into the protrusion integrated with the open wing 13, and when the circular protrusion 15 is pushed, the protrusion is inserted into the hole formed at the center of the opening / closing wing 13.

배관(11)내에 유체가 유입되면 체크밸브의 개폐날개(13)를 통해 유체를 조절한다. 이때 유체의 양이 많으면 체크밸브의 제어를 통해 상기 개폐날개(13)를 조절하여 유체가 적게 유입되게 하고 유체의 양이 적으면 체크밸브의 제어를 통해 개폐날개(13)를 조절하여 유체가 적게 유입되게 한다.When the fluid flows into the pipe 11, the fluid is controlled through the opening and closing wing 13 of the check valve. At this time, if the amount of fluid is large, the control of the check valve to control the opening and closing wing 13 so that less fluid flows, if the amount of the fluid is small to control the opening and closing wing 13 through the control of the check valve to reduce the fluid Allow inflow

한편, 종래에는 유입구를 통해 유체가 유입되면 개폐날개가 오작동되어 유체가 원활하게 흐르지 않거나 체크밸브의 고장으로 인해 유체의 유입 또는 유출이 제대로 되지 않게 된다.On the other hand, conventionally, when the fluid is introduced through the inlet opening and closing wing malfunctions the fluid does not flow smoothly or due to the failure of the check valve is not properly inflow or outflow of the fluid.

또한, 종래에는 개폐날개로 인해 유체가 통과할 수 있는 통로가 좁고 유체가저항받는 제약이 발생하는 문제점이 있었다.In addition, in the related art, there is a problem in that a passage through which the fluid passes through the opening and closing wing is narrow and the fluid is restricted.

또한, 패드가 용접시의 고열로 인해 녹아서 소손되는 문제점도 있었다.In addition, there was also a problem that the pad is melted and burned out due to the high heat during welding.

이에 본 발명은 상술한 바와 같은 제반 문제점을 해결하기 위한 것으로, 그 목적은 유체를 유선형으로 완만하게 흐를수 있도록 완충된 돌기를 통해 조절할 수 있도록 하는 냉매용 프레온가스의 체크밸브를 제공함에 있다.Accordingly, the present invention is to solve the above-mentioned problems, an object of the present invention to provide a check valve of the refrigerant Freon gas for adjusting the buffer so that the fluid flows smoothly streamlined.

본 발명의 다른 목적은 사각형상과 일체로 된 돌기를 거쳐 저항없이 유체가 흐를수 있도록 하는 냉매용 프레온가스의 체크밸브를 제공함에 있다.It is another object of the present invention to provide a check valve of a refrigerant freon gas for allowing a fluid to flow without resistance through a projection integrated with a rectangular shape.

이러한 냉매용 프레온가스의 체크밸브는 스프링(130)의 일측에 삽입된 사각형상과 일체로 된 원형돌기부(140)와, 상기 스프링(130)의 타측에 삽입된 나사형상의 돌기(120)로 이루어져 유체가 상기 원형돌기부(140)를 거쳐 저항없이 흐를 수 있도록 함을 특징으로 한다.The check valve of the refrigerant freon gas is composed of a circular protrusion 140 integrally formed with a square inserted into one side of the spring 130, and a screw-shaped protrusion 120 inserted into the other side of the spring 130. It is characterized in that the fluid flows through the circular protrusion 140 without resistance.

또한, 냉매용 프레온가스의 체크밸브의 돌기(120)는 타원형상으로 형성할 수 있고, 돌기부(140)는 내측면이 구멍(hole)으로 관통되어 형성됨을 특징으로 한다.In addition, the projection 120 of the check valve of the refrigerant freon gas may be formed in an elliptical shape, the projection 140 is characterized in that the inner surface is formed through the hole (hole).

이하, 첨부된 도면에 의거하여 본 발명에 따른 실시예에 대하여 설명하고자 한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 3 은 본 발명 체크밸브의 일실시예의 사시도이고, 도 4 는 본 발명 체크밸브의 일실시예의 단면도이며, 도 5 는 본 발명 유체가 유입되는 방향을 나타낸 체크밸브의 일실시예의 단면도로서, 이를 참조하여 설명하면 다음과 같다.Figure 3 is a perspective view of one embodiment of the check valve of the present invention, Figure 4 is a cross-sectional view of one embodiment of the check valve of the present invention, Figure 5 is a cross-sectional view of an embodiment of a check valve showing the direction in which the fluid flows in the present invention, If described with reference to:

체크밸브의 일측에 형성된 돌기부(140)의 내측에 일측 스프링(130)이 삽입되고, 상기 스프링(130)의 타측에 나사돌기(120)가 삽입된다.One side spring 130 is inserted into the protrusion 140 formed at one side of the check valve, and the screw protrusion 120 is inserted into the other side of the spring 130.

일정 유체(냉매용 프레온가스)가 배관(110)내부로 유입되면 반원형의 나사돌기(120)를 통해 유선형으로 유체가 흘러간다. 이때 유입시 체크밸브의 작동에 의해 나사돌기(120)는 배관(110) 유입구 부분에 있다가 유체가 유입됨에 따라 자동으로 나사돌기(120)가 밀려난다.When a certain fluid (refrigerant freon gas) is introduced into the pipe 110, the fluid flows in a streamline through the semi-circular screw protrusion 120. At this time, the screw protrusion 120 is in the inlet part of the pipe 110 by the operation of the check valve during inflow, and the screw protrusion 120 is automatically pushed out as the fluid is introduced.

상기 나사돌기(120)가 밀려나면서 유체가 다량으로 유입되더라도 유선형 나사돌기(120)에 의해 유체의 흐름이 완만해져 유체 속도를 제어할 수 있게 된다.Even when the screw protrusion 120 is pushed in and the fluid is introduced in a large amount, the flow of the fluid is smoothed by the streamlined screw protrusion 120 to control the fluid velocity.

즉, 나사돌기(120)내에 삽입된 스프링(130)의 완충에 따라 나사돌기(120)의 이동의 완급 조절이 가능하게 된다.That is, according to the buffer of the spring 130 inserted into the screw protrusion 120, it is possible to fully adjust the movement of the screw protrusion 120.

또한, 돌기부(140)와 일체로 형성된 넓게 천공된 직사각 형상을 통해 유출량을 손실없이 내보내게 된다.In addition, through the wide perforated rectangular shape formed integrally with the protrusion 140, the outflow amount is sent out without loss.

도 6 은 본 발명 체크밸브의 다른 일실시예의 사시도로서, 이에 도시된 바와같이 체크밸브의 일측에 형성된 돌기부(140)의 내측에 일측 스프링(130)이 삽입되고, 상기 스프링(130)의 타측에 타원돌기(120-1)가 삽입된다.Figure 6 is a perspective view of another embodiment of the check valve of the present invention, one side spring 130 is inserted into the inner side of the protrusion 140 formed on one side of the check valve, as shown in the other side of the spring 130 The elliptic protrusion 120-1 is inserted.

배관(110)을 통해 유체가 삽입되면 체크밸브(100)의 제어에 타원돌기(120-1)에 삽입된 스프링(130)이 이동하여 유입되는 유체의 양을 조절하게 된다.When the fluid is inserted through the pipe 110, the spring 130 inserted into the elliptic protrusion 120-1 in the control of the check valve 100 is moved to adjust the amount of fluid introduced thereto.

이때, 유체의 양이 많으면 스프링(130)의 완충에 의해 타원돌기(120-1)가 좌측으로 밀려나면서 유체가 원활하게 이동하고, 유체의 양이 적으면 그에 상응하는 스프링(130)의 완충에 의해 타원돌기(120-1)가 이동하여 유체가 출구쪽으로 흐르게 된다.At this time, when the amount of the fluid is large, the elliptic protrusion 120-1 is pushed to the left side by the buffering of the spring 130, and the fluid moves smoothly. The elliptic protrusion (120-1) is moved by the fluid flows toward the outlet.

또한, 본 발명의 돌기부(140)(또는 원형돌기부)는 종래의 개폐날개(13)에 비해 유체의 통로 확보가 용이하여 유체가 원활하게 유출되고, 또한 돌기부(140)로 인해 저항을 적게받아 유체의 이동이 자유롭게 된다.In addition, the protrusion 140 (or the circular protrusion) of the present invention is easier to secure the passage of the fluid compared to the conventional opening and closing wing 13, the fluid is smoothly flowed out, and the fluid received less resistance due to the protrusion 140 Is free to move.

상기 돌기부(140)와 일체로 형성된 사각형상의 유출구로 통해 그 사각형상의유출구로 다량의 유체가 흐르게 된다. 또한, 상기 돌기부(140)의 내측면은 구멍(hole)으로 관통된다.A large amount of fluid flows through the rectangular outlet through the rectangular outlet formed integrally with the protrusion 140. In addition, the inner surface of the protrusion 140 penetrates into a hole.

이상에서 설명한 바와같이, 본 발명은 자중과 유체의 힘에 의하여 밸브를 조절함으로서 밸브의 고장이 현저히 감소하고, 편심날개의 작용이 자중과 유체의 힘에 의하여 작동되므로서 밸브 자체고장으로 인해 유체가 역류되는 현상이 제거되는 효과가 있다.As described above, in the present invention, the valve failure is remarkably reduced by regulating the valve by the self-weight and the force of the fluid, and the action of the eccentric wing is operated by the self-weight and the fluid force. The effect of backflow is eliminated.

또한, 원형돌기 부분을 거침으로서 저항없이 다량의 유체가 흐를수 있는 효과가 있다.In addition, there is an effect that a large amount of fluid can flow without resistance by going through the circular projection portion.
