본 고안은 밸브에 관한 것으로서, 보다 상세하게는 밸브체의 개폐가 원활하면서 패킹이 손상되거나 패킹부위에 누수가 발생되는 것을 방지하도록 된 새로운 밸브에 관한 것이다.The present invention relates to a valve, and more particularly to a new valve to prevent the damage to the packing or leakage of the packing portion while opening and closing the valve body smoothly.
일반적으로, 수도관이나 송유관 등과 같이 유체가 흐르는 관로는 소정위치에 구비된 밸브를 개폐하여 물이나 기름 등의 유체의 공급량을 조절하게 된다. 도 1 내지 도 2은 이러한 종래의 밸브 일례를 도시한 것으로, 이를 참조하면, 상기 밸브는 그 내부에 소정의 유로(1a,1b)가 형성되며 이 유로(1a,1b)의 중앙부에는 밸브시트(1c)가 구비된 밸브하우징(1)과, 저면이 개방된 중공관형태로 이루어지며 그 하단부가 상기 밸브시트(1c)에 밀착되도록 밸브하우징(1)에 나사결합되며 그 중앙부 둘레벽에는 배출구(2c)가 형성된 밸브몸체(2)가 구비된다.In general, a pipe through which a fluid flows, such as a water pipe or an oil pipe, opens and closes a valve provided at a predetermined position to adjust a supply amount of a fluid such as water or oil. 1 to 2 illustrate an example of such a conventional valve. Referring to this, a predetermined flow path 1a, 1b is formed therein, and a valve seat (3) is formed at the center of the flow path 1a, 1b. 1c) is provided in a valve housing (1), and the bottom is formed in the form of a hollow tube, the lower end is screwed to the valve housing (1) so as to be in close contact with the valve seat (1c), the outlet portion ( A valve body 2 having a 2c) is provided.
또한, 상기 밸브몸체(2)의 중공부(2a) 하단부에는 그 둘레부에 수직방향의 통로(3a)가 형성된 베이스부재(3)가 고정설치되며, 이 베이스부재(3)의 상면에는 밸브스템(5)에 연결되어 회전가능하게 밀착설치된 회전밸브체(4)가 구비되는데, 이 회전밸브체(4)의 저면 둘레부에는 상기 베이스부재(3)의 통로(3a) 및 밸브몸체(2)의 배출구(2c)와 연통되도록 방사방향으로 개구된 배출홈(4a)이 형성된다. 또한, 상기 베이스부재(3)의 저면에는 밸브몸체(2)의 중공부(2a) 내벽에 밀착되도록 러버부재로 이루어진 링형상의 패킹(6)이 구비되어 밸브몸체(2)와 밸브시트(1c) 사이에 기밀을 유지할 수 있도록 구성된다.In addition, a base member 3 having a vertical passage 3a formed therein is fixedly installed at a lower end of the hollow portion 2a of the valve body 2, and a valve stem is provided on an upper surface of the base member 3. A rotary valve body 4 connected to (5) to be rotatably mounted is provided, and the passage circumference 3a of the base member 3 and the valve body 2 are provided at the periphery of the bottom of the rotary valve body 4. A radially open discharge groove 4a is formed so as to communicate with the discharge port 2c. In addition, the bottom surface of the base member 3 is provided with a ring-shaped packing (6) made of a rubber member to be in close contact with the inner wall of the hollow portion (2a) of the valve body 2, the valve body 2 and the valve seat (1c) It is configured to maintain confidentiality between).
이때, 상기 밸브의 조립공정을 살펴보면, 먼저 상기 밸브몸체(2)에 밸브스템(5), 회전밸브체(4)와 베이스부재(3) 및 패킹(6)을 순자적으로 조립한상태에서 이 밸브몸체(2)를 그 하단부가 밸브시트(1c)에 밀착되도록 밸브하우징(1)에 나사결합하게 된다.At this time, the assembly process of the valve, first, the valve stem (5), the rotary valve body (4) and the base member (3) and the packing (6) in the valve body 2 in a state of assembled The body 2 is screwed to the valve housing 1 such that the lower end thereof comes into close contact with the valve seat 1c.
따라서, 상기 밸브는 밸브몸체(2)의 외부로 돌출된 밸브스템(5)을 일측으로 회전시켜 회전밸브체(4)의 배출홈(4a)을 베이스부재(3)의 통로(3a)와 연통시켜 유로(1a,1b)를 개방하면 유체가 밸브몸체(2)의 저면의 개구부(2b)를 통해 배출구(2c)로 배출된다. 이어서, 상기 밸브스템(5)을 원상복귀시키면 회전밸브체(4)가 베이스부재(3)의 통로(3a)를 폐쇄하여 유로(1a,1b)를 폐쇄하게 된다.Accordingly, the valve rotates the valve stem 5 protruding out of the valve body 2 to one side so that the discharge groove 4a of the rotary valve body 4 communicates with the passage 3a of the base member 3. When the flow paths 1a and 1b are opened, the fluid is discharged to the discharge port 2c through the opening 2b at the bottom of the valve body 2. Subsequently, when the valve stem 5 is returned to its original position, the rotary valve body 4 closes the passage 3a of the base member 3 to close the flow paths 1a and 1b.
그런데, 이러한 종래의 밸브는 상기 밸브몸체(2)의 중공부(2a)에 패킹(6)과 베이스부재(3) 및 회전밸브체(4)가 서로 밀착되게 구비되어 있으므로, 이 밸브몸체(2)를 밸브시트(1c)에 가압밀착되도록 밸브하우징(1)에 나사결합할 때 밸브몸체(2)를 과도하게 조이면 회전밸브체(4)와 베이스부재(3) 및 패킹(6)이 조임력에 의해 서로 가압밀착되어, 회전밸브체(4)의 작동이 원활하지 못하는 등의 문제점이 있다.By the way, such a conventional valve is provided with the packing 6 and the base member 3 and the rotary valve body 4 in close contact with each other in the hollow portion 2a of the valve body 2, so that the valve body 2 ) When screwing the valve body 2 excessively when screwing the valve housing 1 so that the valve seat 1c is pressed tightly to the valve seat 1c, the rotary valve body 4, the base member 3, and the packing 6 are subjected to the tightening force. Thereby, there is a problem in that the pressure-adhering contact with each other, the operation of the rotary valve body 4 is not smooth.
또한, 상기 밸브는 유로(1a,1b)가 개방된 상태에서 회전밸브체(4)를 회전시켜 유로(3,5)를 폐쇄하게 되면, 이 회전밸브체(30)를 갑작스럽게 잠금에 따른 유체의 급격한 압력변화 등에 의해 수격이 발생하게 되는데, 이러한 경우, 수격에 의해상기 러버부재로 된 패킹(6)이 밸브몸체(2)의 외측으로 밀려나가 밸브몸체(2)의 하단부와 밸브시트(1c) 사이의 틈새로 밀려나 누수가 발생되고 패킹(6)이 손상되는 등의 문제점이 있다.In addition, when the valve closes the flow paths 3 and 5 by rotating the rotary valve body 4 in a state in which the flow paths 1a and 1b are opened, the valve fluid suddenly locks the rotary valve body 30. The water hammer is generated due to a sudden pressure change, etc. In this case, the packing 6 made of the rubber member is pushed out of the valve body 2 by the water hammer, so that the lower end of the valve body 2 and the valve seat 1c. There is a problem that is pushed into the gap between the) and leakage occurs and the packing 6 is damaged.
본 고안은 전술한 바와 같은 문제점을 해결하기 위해 제안된 것으로서, 본 고안의 목적은 회전밸브체의 개폐가 원활하면서 패킹이 손상되거나 패킹부위에 누수가 발생되는 것을 방지하도록 수 있도록 된 새로운 밸브를 제공하기 위한 것이다.The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a new valve that can prevent the packing from being damaged or leaks from the packing portion while opening and closing the rotary valve body smoothly. It is to.

Even if it is excessively tightened, the stepped portion 64 is configured to limit the pressing force applied to the rotary valve body 40. In addition, the upper circumferential portion of the ring body 62 is formed with a locking groove 69 which is concave inward so as to be caught by the locking jaw 28 of the hollow portion 22, and the ring body 62 is formed by the locking groove 69. ) Is coupled to the locking step 28 in a one-touch manner. At this time, the locking groove 69 is preferably formed to extend to the upper surface of the stepped portion 64 of the ring body 62 so that the ring body 62 can flow in the vertical direction, thereby forming the valve body 20. When tightened, the packing 68 provided on the upper and lower surfaces of the ring body 62 is pressed to prevent leakage.
또한, 상기 링체(62)의 상하면에는 오목한 링형상의 상하부 패킹안착홈(66,67)이 형성되고, 이 상하부 패킹안착홈(66,67)에는 러버부재로 이루어진 패킹(68)이 각각 결합된다. 이때, 상기 패킹안착홈(66,67)의 깊이와 폭은 패킹(68)이 약간 눌려져 결합되도록 하므로써, 결합된 패킹(68)이 쉽게 이탈되지 않는 사이즈로 형성함이 바람직하다.Further, upper and lower concave ring-shaped upper and lower packing seating grooves 66 and 67 are formed on upper and lower surfaces of the ring body 62, and packings 68 made of rubber members are coupled to the upper and lower packing seating grooves 66 and 67, respectively. . At this time, the depth and width of the packing seating grooves (66, 67) is preferably formed by the size of the combined packing 68 is not easily separated by being pressed by the packing 68 slightly.
이러한 밸브의 조립공정을 살펴보면, 먼저 상기 링체(62) 상하부 패킹안착홈(66,67)에 패킹(68)을 결합한 다음, 상기 밸브몸체(20)의 중공부(22)에 밸브스템(50)과 회전밸브체(40) 및 베이스부재(30)를 순자적으로 삽입한 후 이 중공부(22) 하단의 걸림턱(28)에 패킹(68)이 결합된 링체(62)를 원터치식으로 끼움결합한 상태에서 이 밸브몸체(20)를 밸브시트(16)에 밀착되도록 밸브하우징(10)에 나사결합하게 된다.Looking at the assembly process of such a valve, first coupling the packing 68 in the upper and lower packing seating grooves (66, 67) of the ring body 62, and then the valve stem (50) to the hollow portion 22 of the valve body (20) And the rotary valve body 40 and the base member 30 are sequentially inserted, and the ring body 62 having the packing 68 coupled to the locking jaw 28 at the bottom of the hollow part 22 is fitted in a one-touch manner. In the coupled state, the valve body 20 is screwed to the valve housing 10 to be in close contact with the valve seat 16.
이러한 구성에 따르면, 상기 밸브의 실링수단(60)은 링체(62)의 하단 둘레부에 밸브몸체(20)의 하단부에 걸려지는 단턱부(64)가 형성되어 상기 밸브몸체(20)를 밸브시트(16)에 가압밀착되도록 밸브하우징(10)에 과도하게 조이더라도 상기 단턱부(64)에 의해 링체(62)가 밸브봄체(20)의 하단부에 걸려져 회전밸브체(40)에 가해지는 가압력을 제한하게 되므로, 회전밸브체(40)의 작동이 원활한 장점이 있다.According to this configuration, the sealing means 60 of the valve is formed in the lower end of the ring body 62, the stepped portion 64 is caught on the lower end of the valve body 20 to form the valve body 20 valve seat Even if the valve housing 10 is excessively tightened so as to be in close contact with the valve 16, the pressing force applied to the rotary valve body 40 by the ring body 62 is caught by the lower end of the valve spring body 20 by the stepped portion 64. Since it is limited, the operation of the rotary valve body 40 has a smooth advantage.
또한, 상기 실링수단(60)의 패킹(68)은 링체(62)의 상하부 패킹안착홈(66,67)에 그 둘레부가 감싸지도록 결합되어 있으므로, 수격이 발생하더라도 패킹(68)이 강성체로 된 링체(62)에 의해 지지되어 밸브몸체(2)와밸브시트(16) 사이의 틈새로 밀려나가는 것을 방지하게 되므로, 패킹손상과 이에 따른 누수 등이 발생되는 것을 방지할 수 있는 장점이 있다.In addition, since the packing 68 of the sealing means 60 is coupled to the upper and lower packing seating grooves 66 and 67 of the ring body 62 so as to surround the circumferential part, the packing 68 is made of a rigid body even when water hammer occurs. It is supported by the ring body 62 to prevent being pushed into the gap between the valve body 2 and the valve seat 16, there is an advantage that can prevent the packing damage and the resulting leakage.
이상에서와 같이 본 고안에 의하면, 상기 밸브는 밸브몸체를 밸브시트에 가압밀착되도록 밸브하우징에 과도하게 조이더라도 상기 실링수단의 하단 둘레부에 형성된 단턱부가 밸브몸체의 하단부에 걸려져 회전밸브체에 가해지는 가압력을 제한하게 되므로, 회전밸브체의 작동이 원활한 장점이 있다. 또한, 패킹이 링체의 상하부 패킹안착홈에 그 둘레부가 감싸지도록 결합되어 있으므로, 이 패킹에 수격이 작용하더라도 손상되거나 실링위치로부터 이탈되어 누수 등의 발생되는 것을 방지할 수 있는 장점이 있다.As described above, according to the present invention, even if the valve body is excessively tightened in the valve housing so that the valve body is pressed tightly to the valve seat, the stepped portion formed at the lower periphery of the sealing means is caught by the lower end of the valve body and is connected to the rotary valve body. Since the applied pressure is limited, there is a smooth operation of the rotary valve body. In addition, since the packing is coupled to the upper and lower packing seating groove of the ring body so as to surround the circumference thereof, there is an advantage that even if the water hammer acts on the packing, it is prevented from being damaged or released from the sealing position to cause leakage.
