Description

가변식 정유량밸브{ADJUSTABLE BALANCING VALVE}ADJUSTABLE BALANCING VALVE [0002]

본 발명은 가변식 정유량밸브에 관한 것으로, 더욱 상세하게는 카트리지하우징이 밸브샤프트에 의해 상하이동하도록 조정하여 정유량값을 설정할 수 있도록 구성되는 가변식 정유량밸브에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a variable flow rate valve, and more particularly, to a variable flow rate valve configured to allow a cartridge housing to move up and down by a valve shaft to set a constant flow rate value.

일반적으로 정유량 밸브는 관로를 통해 이동되는 유체의 유량 증가에 따라 유로 단면적을 줄여 유입단에서 유출단으로 통과되는 유량을 일정하게 유지시키는 것으로, 일반주택이나 아파트 등의 건물 난방시스템에 정유량 밸브가 설치되는 것이 일반적이다.In general, the constant flow valve reduces the cross-sectional area of the flow passage in accordance with the increase of the flow rate of the fluid flowing through the pipeline, thereby maintaining a constant flow rate from the inflow end to the outflow end. Is generally installed.

이때, 건물에 설치되는 보일러 시스템에는 난방을 필요로 하는 각방에 난방수를 분배하는 각방 온수분배기가 설치되어 있고, 이러한 각방 온수분배기는 보일러의 열교환기로부터 가열된 난방수를 난방수 공급관을 통해 공급받아 각방으로 난방수를 공급하며, 상기 공급된 난방수는 각방에 열에너지를 전달한 후 냉각되어 난방수 환수관으로 이송되어지도록 구성되어 있다.In this case, the boiler system installed in the building is provided with a hot water dispenser for distributing the heating water to each room requiring heating. The hot water dispenser for heating the hot water from the heat exchanger of the boiler is supplied through the heating water supply pipe The heating water is supplied to each room, and the supplied heating water is transferred to the heating water receiving pipe after cooling the heat energy to each room.

이러한 각방 온수 분배기에는 각방으로 공급되는 난방수의 유량을 조절하는 조절밸브가 설치되는데, 이러한 조절밸브의 하나로 정유량 밸브가 사용되는 것이다.In such a hot water dispenser, a regulating valve is provided to regulate the flow rate of the heating water supplied to each room. A constant flow valve is used as one of the regulating valves.

여기서, 정유량 밸브는 밸브 자체에 설정된 유량 이상으로는 난방수가 흐르지 않게 하기 위한 것으로, 건물에 여러 개의 방이 있고 보일러 하나에서 여러 개의 방에 난방수를 공급하는 경우 각 방의 배관 길이가 상이함으로 인해 각 방의 온도가 설정온도에 도달하는 시간은 서로 상이하게 된다.Here, the constant flow valve is provided to prevent the heating water from flowing above the flow rate set in the valve itself. When there are several rooms in the building and the heating water is supplied to several rooms from one boiler, The time at which the temperature of the room reaches the set temperature becomes different from each other.

따라서 이러한 난방 불균형을 해소하기 위하여 각 세대마다 공급되는 난방수 배관상에 정유량밸브를 설치함으로써 항상 일정한 유량이 공급되도록 한다.Therefore, in order to solve such a heating imbalance, a constant flow rate valve is provided on the heating water pipe supplied for each generation, so that a constant flow rate is always supplied.

각 세대의 여러 방들에는 각 방마다 온도조절기가 설치되어 있는 것이 보통이고, 사용자의 필요에 따라 특정한 방의 난방을 중단하기 위해, 난방수의 공급을 차단하는 밸브가 설치된다.Each room has a temperature controller installed in each room, and a valve is provided to shut off the supply of heating water in order to stop the heating of a particular room according to the user's needs.

따라서, 세대 내에서 일부 방의 난방이 중지되거나 가동이 되는 상태에 따라나머지 방들의 유량값이 변화하게 되고, 변화된 각 방의 난방부하에 맞게 세대별로 공급되는 난방수의 유량이 변화되어야 한다.Accordingly, the flow rate value of the remaining rooms changes depending on the state in which the heating of some of the rooms is stopped or operated in the household, and the flow rate of the heating water supplied for each household needs to be changed according to the heating loads of the changed rooms.

그러나, 종래의 정유량 밸브는 인입라인의 압력변화 및 난방부하의 변화에도 항상 일정한 유량을 공급하도록 설계되어 과유량에 의한 소음발생 및 불필요한 에너지 소비 등의 문제가 초래된다.However, the conventional constant flow valve is designed to always supply a constant flow rate to a change in the pressure of the inlet line and a change in the heating load, resulting in generation of noise due to the flow rate and unnecessary energy consumption.

특히, 하기의 특허문헌2에는 본체의 내주면을 따라 원통체가 좌우이동하면서 돌기부의 위치를 이동시켜 밸브체에 의한 유량을 조절하도록 구성되는 정유량밸브가 기재되어 있다.Particularly, the following Patent Document 2 discloses a constant flow valve configured to adjust the flow rate of the valve body by moving the position of the protrusion while the cylindrical body moves left and right along the inner circumferential surface of the body.

그러나, 특허문헌2의 정유량밸브는 회전샤프트에 의해 웜이 회전되면 웜과 치결합되어 있는 웜휠이 회전되고, 웜휠과 나사결합된 원통체가 웜휠의 회전방향에 따라 좌우이동하도록 구성되어, 유량을 조절하기 위한 밸브체의 구동구조가 매우 복잡하면서 조작이 불편하고, 그 제조비용이 과다하다는 등의 문제가 있다.However, in the constant flow valve of Patent Document 2, when the worm is rotated by the rotating shaft, the worm wheel, which is coupled to the worm, is rotated, and the cylindrical body screwed with the worm wheel moves left and right in accordance with the rotating direction of the worm wheel. There is a problem that the driving structure of the valve body for controlling the valve is very complicated and the operation is inconvenient and the manufacturing cost is excessive.

도1은 본 발명에 따른 가변식 정유량밸브의 일 실시예를 예시하는 단면도이다.1 is a cross-sectional view illustrating one embodiment of a variable flow rate valve according to the present invention.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 보다 구체적으로 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 그 일 실시예에 따르면, 도1에 도시된 바와 같이 유입구(2)와 유입유로(3) 그리고 유출유로(4)와 유출구(5)를 연결하는 밸브유로(6)가 구비되는 밸브몸체(1)와, 밸브샤프트(10)에 의해 상기 밸브유로(6)를 따라 상하이동되면서 내주면 상단에 유량조절부재(35)가 구비되는 카트리지하우징(30)과, 상기 카트리지하우징(30)에 내장되어 밸브스프링(20)에 의해 밸브샤프트(10)를 따라 상하탄성이동을 하면서 유로홈(41)의 개도량을 조절하는 카트리지(40)로 구성되어 있다.1, according to one embodiment of the present invention, the valve 2 is provided with a valve passage 6 for connecting the inlet 2, the inlet 3, and the outlet 4 with the outlet 5, A cartridge housing 30 in which a flow rate regulating member 35 is provided at an upper end of an inner peripheral surface of the cartridge housing 30 while being vertically moved along the valve channel 6 by a valve shaft 10, And a cartridge 40 for regulating the amount of opening of the flow path groove 41 while moving upward and downward along the valve shaft 10 by the valve spring 20.

이때, 밸브몸체(1)는 난방수가 유입구(2)를 통해 유입되어 유입유로(3)와 밸브유로(6) 그리고 유출유로(4)를 거쳐 유츌구(5)로 배출되도록 구성되어 있고, 밸브유로의 하단에 밸브시트(9)가 구비되어 있다.At this time, the valve body 1 is configured such that the heating water flows through the inlet port 2 and is discharged to the oil port 5 through the inflow channel 3, the valve channel 6 and the outflow channel 4, And a valve seat 9 is provided at the lower end of the flow path.

그리고, 일반적으로 전동구동기 등에 연결되면서 상하이동거리가 제어되도록 구성되는 밸브샤프트(10)는 그 상단부가 밸브콘(11)에 의해 밸브몸체(1)의 상부에 지지되고, 그 하단이 카트리지하우징(30)의 카트리지캡(31)에 고정되도록 구성되어 있다.The upper end of the valve shaft 10, which is generally configured to be controlled in the up-and-down movement distance while being connected to an electric driver or the like, is supported on the upper portion of the valve body 1 by the valve cone 11, 30 to the cartridge cap 31. As shown in Fig.

여기서, 카트리지하우징(30)은 밸브유로(6)에 실링상태로 상하강되도록 내장되면서 그 내주면 상단에 유량조절부재(35)가 구비되고, 그 하단에 카트리지캡(31)이 나사결합상태로 삽입된다.The cartridge housing 30 is installed in the valve channel 6 in a sealed state so that the cartridge housing 30 is provided with a flow rate regulating member 35 at the upper end of the inner circumferential surface thereof and the cartridge cap 31 is inserted do.

이때, 카트리지캡(31)은 그 중앙에 밸브샤프트(10)의 하단이 고정 삽입되어 있고, 다수의 유로가 구비되어 유로홈(41)을 통해 유입되는 유체를 배출하도록 구성되며, 그 하부 내측에 스트레이너(60)가 끼워지면서 그 하부 외측에 카트리지고무패킹(32)이 끼워지도록 구성되어 있다.At this time, the lower end of the valve shaft 10 is fixedly inserted into the center of the cartridge cap 31, and a plurality of flow paths are provided to discharge the fluid flowing through the flow path groove 41, The strainer 60 is inserted and the cartridge rubber packing 32 is fitted on the lower outer side thereof.

특히, 스트레이너(60)는 반구형상을 이루면서 유체의 이물질을 필터링하도록 구성되어 있고, 카트리지고무패킹(32)은 카트리지하우징(30)이 완전히 하강되면 밸브시트(9)에 안착되면서 유체가 유출유로(4)로 배출되지 않도록 완전히 차단할 수 있도록 구성되어 있다.In particular, the strainer 60 is configured to filter the foreign matter of the fluid in a semispherical shape, and the cartridge rubber packing 32 is seated on the valve seat 9 when the cartridge housing 30 is completely lowered, 4 so as not to be discharged.

또한, 카트리지(40)는 유량조절부재(35)와 밸브샤프트(10)를 따라 상하강되도록 카트리지하우징(30)에 내장되어 있고, 그 외주면에 유로홈(41)이 구비되는데 카트리지하우징(30)의 유량조절부재(35)를 기준하여 유로홈의 유체입출구크기가 결정되도록 구성되어 있다.
다시 말하면, 카트리지(40)의 유로홈(41)은 유량조절부재(35)에 의해 분할되면서 유량조절부재(35)의 상부측에 위치하는 부분이 카트리지의 내부로 유체를 유입하는 유체의 입구가 되지만, 유량조절부재(35)의 하부측에 위치하는 부분은 카트리지 내의 유체를 외부로 배출하는 유체의 출구가 된다.
따라서, 카트리지(40)가 상승되면 유량조절부재(35)의 상부측에 위치하는 유로홈(41)의 부분이 커지는 만큼 유량조절부재(35)의 하부측에 위치하는 유로홈(41)의 부분이 작아지면서 배출유량을 감소시키도록 작용하게 된다.
반대로, 카트리지(40)가 하강되면 유량조절부재(35)의 상부측에 위치하는 유로홈(41)의 부분이 감소하는 만큼 유량조절부재(35)의 하부측에 위치하는 유로홈(41)의 부분이 커지면서 배출유량을 상승시키도록 작용하게 된다.
여기서, 밸브샤프트(10)의 하부측에 끼워지는 밸브스프링(20)은 와셔(12)에 의해 압축되면서 카트리지하우징(30)과 카트리지(40)에 압축탄성력이 작용하도록 구성되어 있다.The cartridge 40 is accommodated in the cartridge housing 30 so as to be lifted up and down along the flow regulating member 35 and the valve shaft 10. The cartridge 40 is provided with a flow groove 41 on the outer circumferential surface thereof, The size of the fluid inlet / outlet of the flow path groove is determined based on the flow rate regulating member 35 of the flow rate regulating member 35.
In other words, the flow path groove 41 of the cartridge 40 is divided by the flow rate regulating member 35 so that the portion located on the upper side of the flow rate regulating member 35 is connected to the inlet of the fluid However, the portion located on the lower side of the flow rate regulating member 35 serves as an outlet of the fluid for discharging the fluid in the cartridge to the outside.
Therefore, when the cartridge 40 is lifted up, the portion of the flow path groove 41 located at the lower side of the flow rate regulating member 35 becomes larger as the portion of the flow path groove 41 located at the upper side of the flow rate regulating member 35 becomes larger, Becomes smaller and acts to reduce the discharge flow rate.
On the contrary, when the cartridge 40 is lowered, the portion of the flow path groove 41 located on the lower side of the flow rate regulating member 35 decreases as the portion of the flow path groove 41 located on the upper side of the flow rate regulating member 35 decreases Thereby increasing the discharge flow rate.
Here, the valve spring 20 fitted to the lower side of the valve shaft 10 is configured to apply a compressive elastic force to the cartridge housing 30 and the cartridge 40 while being compressed by the washer 12.

한편, 밸브샤프트(10)를 상승시키게 되면 카트리지하우징(30)과 카트리지(40) 또한 상승되면서 밸브스프링(20)을 압축시키게 되고, 밸브스프링이 압축되면서 그 압축탄성력이 보다 증가되어 카트리지(40)의 상승을 억제하도록 작용하게 된다.When the valve shaft 10 is raised, the cartridge housing 30 and the cartridge 40 are also lifted to compress the valve spring 20, and the compression spring force of the valve spring 20 is further increased, As shown in Fig.

이때, 보다 강해진 밸브스프링(20)의 압축탄성력에 의해 유로홈(41)은 유량조절부재(35)의 하부측에 위치하는 부분이 커지면서 개도량을 점차 증가시키어 유량의 증가를 유도하도록 작용하게 된다.At this time, due to the compressive elastic force of the valve spring 20, which is stronger, the flow grooves 41 increase in the portion located on the lower side of the flow rate regulating member 35 and gradually increase the opening amount, .

반대로, 밸브샤프트(10)를 하강시키게 되면 카트리지하우징(30)이 함께 하강되면서 카트리지(40) 또한 밸브스프링(20)의 압축탄성력에 의해 하강되는데, 이때 밸브스프링(20)은 이완되면서 그 압축탄성력이 보다 감소되어 카트리지(40)의 상승이 점차 가능하도록 작용하게 된다.Conversely, when the valve shaft 10 is lowered, the cartridge housing 30 is lowered together and the cartridge 40 is also lowered by the compressive elastic force of the valve spring 20. At this time, the valve spring 20 relaxes, So that the upward movement of the cartridge 40 is allowed to gradually become possible.

이때, 보다 약해진 밸브스프링(20)의 압축탄성력에 의해 유로홈(41)은 유량조절부재(35)의 상부측에 위치하면서 개도량을 점차 감소시키어 유량의 감소를 유도하도록 작용하게 된다.At this time, the flow grooves 41 are located on the upper side of the flow rate regulating member 35 by the compressive elastic force of the valve spring 20, which is weakened, so that the opening amount is gradually decreased to act to induce the decrease of the flow rate.

이와 같이, 본 발명의 상세한 설명에서는 구체적인 실시예에 관해 설명하였으나, 이는 본 발명의 범주에서 벗어나지 않는 한도내에서 여러가지 변형이 가능함은 물론이다.Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

그러므로, 본 발명의 실질적인 범위는 상술된 실시예에 의해 한정되어져서는 안되며, 후술하는 청구범위 뿐만 아니라 청구범위와 균등한 구성에 의해 정해져야 함은 당연하다.Therefore, it should be understood that the practical scope of the present invention should not be limited by the above-described embodiments, but should be determined by the constitution equivalent to the claims, as well as the claims described below.
