Description

벨로우즈형 신축밸브{Bellows type flexible valve}Bellows type flexible valve

본 발명은 밸브본체의 일측 접속플랜지에 신축관이 가압링과 패킹링에 의해 기밀되게 삽입 설치된 벨로우즈형 신축밸브에 관한 것으로, 더욱 상세하게는 신축관이 밸브본체에 체결 고정되지 않고 밸브본체의 일측 접속플랜지와 접속되는 관로에 체결 고정된 구조로 이루어져, 설치상태에서 신축관은 밸브본체의 내경 안에서 자유롭게 습동됨에 따라, 관로의 팽창 및 수축 현상을 효과적으로 흡수함으로써, 관로 계통의 시설도 보호하여 누수에 대한 우려를 완전히 해소할 수 있게 한 벨로우즈형 신축밸브에 관한 것이다.
The present invention relates to a bellows type expansion valve in which the expansion pipe is airtightly inserted into the connecting flange of the valve body by a pressure ring and a packing ring. More specifically, the expansion pipe is not fastened to the valve body and fixed to one side of the valve body. Consisting fastened to the pipe connected to the connection flange, the expansion pipe is freely slid in the inner diameter of the valve body, effectively absorbing the expansion and contraction of the pipe, thereby protecting the facility of the pipeline system to prevent leakage. The present invention relates to a bellows type expansion valve that can completely solve the concern.

일반적으로 밸브는 접속플랜지가 고정식으로 일체로 구성되어 있으므로 밸브의 교체시 패킹과 함께 새로운 밸브의 연결이 용이하지 않아 관을 절단하여 연결하고 다시 용접하는 방법으로 밸브를 교체해야만 하였다. In general, since the valve is connected to the fixed flange integrally, when the valve is replaced, the new valve with the packing is not easy to connect, so the valve has to be replaced by cutting and connecting the pipe.

이로 인해 밸브를 교체하는 작업이 번거롭고 단수시간도 길어지는 등의 문제점이 있었다. 따라서 상기의 문제점을 해소하기 위하여 실용신안등록 제0234934호의 벨로우즈형 신축밸브가 안출되어 등록되었다. As a result, there is a problem in that the work of replacing the valve is cumbersome, and the short time is also long. Therefore, in order to solve the above problem, the bellows type expansion valve of Utility Model Registration No. 0234934 was registered and registered.

이는 유동관과 유동플랜지의 사이에 신축이 자유로운 벨로우즈를 부설한 신축관을 패킹링과 가입링을 매개로 밸브본체의 일측 접속플랜지에 수밀되게 설치한 구조로서, 상기 신축관의 유동관이 밸브본체의 내경 안에서 습동되도록 한 구조이다. It is a structure in which a flexible pipe with a freely expandable bellows is installed between the flow pipe and the flow flange in a connection flange of one side of the valve body through a packing ring and a joining ring, and the flow pipe of the flexible pipe is the inner diameter of the valve body. It is a structure that allows it to slide inside.

따라서 밸브의 교체시 신축관의 삽입길이를 조절하여 밸브의 면간 거리를 배관의 필요에 따라 조절할 수 있으므로 밸브의 교체를 관체의 절단과 용접 작업의 번거로움 없이 간단하게 할 수 있다. Therefore, when the valve is replaced, the distance between the valves can be adjusted according to the needs of the pipe by adjusting the insertion length of the expansion pipe, so that the replacement of the valve can be simplified without the hassle of cutting and welding work.

그리고 신축관의 벨로우즈는 상하좌우로 자유롭게 굴곡됨에 따라 밸브를 매개로 접속되는 양측의 관로가 각도 상에서 서로 어긋나더라도 편리하게 맞추어 연결할 수 있다.
And since the bellows of the expansion pipe is bent freely up, down, left and right, even if the pipes on both sides connected via the valve are shifted from each other in an angle, it can be conveniently matched.

그러나 상기한 종래의 벨로우즈형 신축밸브 역시 벨로우즈를 구비한 신축관이 설치되어 있음에 불구하고 설치상태에서는 관로의 팽창 및 수축현상에 대하여 신축반력을 전혀 발휘하지 못한다. However, the above-described conventional bellows-type expansion valve also exhibits no elastic reaction against expansion and contraction of the pipeline even when the expansion pipe having bellows is installed.

이는 설치상태에서 신축관이 상하로 유동되지 않도록 관로와 밸브본체의 사이에 하나의 볼트로서 가압링과 함께 관로와 밸브본체에 일체로 고정되어 있기 때문이다. This is because it is integrally fixed to the pipeline and the valve body together with a pressure ring as a bolt between the pipeline and the valve body so that the expansion and contraction pipe does not flow up and down in the installed state.

따라서 관로와 밸브본체의 사이 간격이 일정하게 유지됨에 따라, 신축관은 유체의 흐름방향으로의 신축이 불가능하게 됨으로써 밸브본체의 내경 안에서 축방향으로의 자유롭게 습동할 수 없게 된다. Therefore, as the distance between the conduit and the valve body is kept constant, the expansion and contraction tube is unable to expand and contract in the flow direction of the fluid, and thus cannot freely slide in the axial direction within the inner diameter of the valve body.

이에 따라 상기한 종래의 벨로우즈형 신축밸브도 관로의 팽창 및 수축현상에 대하여 제기능을 전혀 발휘하지 못하게 됨으로써, 신축관이 한쪽으로 쳐지거나 비틀려 밸브본체와 신축관의 사이에서 누수가 발생되고, 이에 따라 수명이 단축되고 유체의 낭비를 가져오는 등 실제로 관로 계통에서 원활한 운전이 되지 못하는 문제점을 가지고 있다. Accordingly, the above-described conventional bellows type expansion valve cannot exert any function against expansion and contraction of the pipeline, so that the expansion pipe is struck or twisted to one side, and water leaks between the valve body and the expansion pipe. Accordingly, there is a problem in that the service life is not smoothly operated in the pipeline system, such as shortening the life and waste of fluid.

본 발명은 상기와 같은 문제점을 해소하기 위하여 발명된 것으로, 설치상태에서 관로의 팽창 및 수축현상이 발생될 때 신축반력을 제대로 발휘하여 누수가 전혀 없이 유체의 흐름을 원활하게 할 수 있도록, 접속플랜지가 양측에 구비된 밸브본체와; 밸브본체의 접속플랜지에 삽입되어 습동되는 유동관과, 관로에 체결되는 유동플랜지와, 유동관과 유동플랜지의 사이에 설치되어 길이방향으로 신축되는 벨로우즈로 구성된 신축관과; 밸브본체의 접속플랜지와 유동관의 사이에 설치된 패킹링과; 밸브본체의 접속플랜지에 볼트와 너트로 체결되어 패킹링을 가압하는 가압링을; 포함한 벨로우즈형 신축밸브에 있어서, 상기 유동관의 외주면에 볼트공이 뚫린 복수개의 체결플랜지가 일정간격으로 설치되어 신축관과 함께 체결플랜지가 볼트와 너트로서 관로에 체결되는 구조로 구성된 벨로우즈형 신축밸브를 제공함에 그 목적이 있다.
The present invention has been invented to solve the above problems, when the expansion and contraction phenomenon of the pipeline in the installation state to properly exert the elastic reaction force to smoothly flow the fluid without any leakage, connection flange A valve body provided at both sides; A flexible pipe composed of a flow pipe inserted into the connection flange of the valve body and slidable, a flow flange fastened to the pipe line, and a bellows installed between the flow pipe and the flow flange and stretched in a longitudinal direction; A packing ring installed between the connecting flange of the valve body and the flow pipe; A pressure ring which is fastened to the connection flange of the valve body with a bolt and a nut to press the packing ring; In the bellows-type expansion valve including, a plurality of fastening flanges with bolt holes drilled on the outer circumferential surface of the flow pipe is provided at regular intervals to provide a bellows-type expansion valve composed of a structure in which the fastening flange together with the expansion pipe is fastened to the pipeline as bolts and nuts. Has its purpose.

본 발명은 밸브본체의 내경 안에서 신축관이 자유롭게 습동되는 구조를 가짐에 따라, 밸브의 교체시 밸브의 면간 거리를 자유롭게 조절할 수 있으므로 밸브의 교체 작업을 매우 편리하게 할 수 있는 효과가 있다. 그리고 설치상태에서도 신축관이 밸브본체의 내경 안에서 자유롭게 유체의 흐름방향으로 습동되는 구조를 가짐에 따라 관로의 팽창 및 수축 현상을 효과적으로 흡수할 수 있으므로 관로 계통의 시설을 보호하여 누수에 대한 우려를 완전히 해소할 수 있는 효과가 있다.
According to the present invention, since the expansion pipe is freely slid in the inner diameter of the valve body, the distance between the surfaces of the valve can be freely adjusted when the valve is replaced, thereby making the valve replacement work very convenient. Also, even when installed, the expansion pipe can freely slide in the flow direction of the fluid within the inner diameter of the valve body, so that the expansion and contraction of the pipeline can be effectively absorbed. There is an effect that can be solved.

본 발명의 벨로우즈형 신축밸브(100)는 접속플랜지(1)(2)가 양측에 구비된 밸브본체(3)와; 밸브본체(3)의 접속플랜지(1)에 삽입되어 습동되는 유동관(4)과, 관로(A)에 체결되는 유동플랜지(5)와, 유동관(4)과 유동플랜지(5)의 사이에 설치되어 유체의 흐름방향으로 신축되는 벨로우즈(6)로 구성된 신축관(7)과; 밸브본체(3)의 접속플랜지(1)와 유동관(4)의 사이에 설치된 패킹링(8)과; 밸브본체(3)의 접속플랜지(1)에 볼트(9)와 너트(10)로 체결되어 패킹링(8)을 가압하는 가압링(11)을; 포함한 벨로우즈형 신축밸브에 있어서, 상기 유동관(4)의 외주면에 볼트공(12)이 뚫린 복수개의 체결플랜지(13)가 일정간격으로 설치되어, 신축관(7)과 함께 체결플랜지(13)는 볼트(14)와 너트(15)로서 관로(A)에 체결되는 구조로 이루어져 있다. Bellows-type expansion valve 100 of the present invention includes a valve body (3) provided with connecting flanges (1) (2) on both sides; It is installed between the flow pipe 4 inserted into the connection flange 1 of the valve body 3 and slid, the flow flange 5 fastened to the pipe line A, and between the flow pipe 4 and the flow flange 5. An extension pipe (7) composed of bellows (6) which are expanded and contracted in the flow direction of the fluid; A packing ring 8 provided between the connecting flange 1 of the valve body 3 and the flow pipe 4; A pressure ring 11 fastened to the connection flange 1 of the valve body 3 by a bolt 9 and a nut 10 to press the packing ring 8; In the bellows-type expansion valve including, a plurality of fastening flanges 13 through which bolt holes 12 are drilled on the outer circumferential surface of the flow pipe 4 are installed at regular intervals, the fastening flange 13 together with the expansion pipe 7 The bolt 14 and the nut 15 are configured to be fastened to the pipe line A.

도면 중 미설명 부호 B는 밸브본체(3)의 타측 접속플랜지(2)에 접속되는 관로이다. In the figure, reference numeral B denotes a conduit connected to the other connection flange 2 of the valve body 3.

이와 같이 구성된 본 발명의 벨로우즈형 신축밸브(100)는 도 1 내지 도 2에 도시된 바와 같이 밸브본체(3)의 일측에 자유롭게 습동되는 신축관(7)이 설치되어, 밸브의 면간 거리를 자유롭게 조절할 수 있어 밸브의 교체 작업을 용이토록 한 밸브이다. Bellows-type expansion valve 100 of the present invention configured as described above is provided with a flexible tube (7) that is freely sliding on one side of the valve body 3, as shown in Figure 1 to 2, to freely the distance between the surface of the valve It is adjustable to facilitate valve replacement.

특히, 본 발명은 관로(A)(B)에 설치한 상태에서도 신축관(7)이 밸브본체(3)의 내경 안에서 유체의 흐름방향으로 자유롭게 습동됨으로써 관로의 팽창 및 수축 현상을 효과적으로 대응할 수 있도록 한 것이 큰 특징이다. In particular, the present invention is to expand and contract the expansion and contraction phenomena of the pipeline effectively by the flexible pipe (7) is free to slide in the flow direction of the fluid within the inner diameter of the valve body 3 even when installed in the pipeline (A) (B) One thing is a big feature.

이는 도 3 내지 도 4에 도시된 바와 같이, 신축관(7)을 구성하는 유동관(4)의 외주면에 볼트공(12)이 뚫린 복수개의 체결플랜지(13)가 일정간격으로 설치되어, 신축관(7)과 함께 체결플랜지(13)는 볼트(14)와 너트(15)로서 관로(A)에 체결되는 구조로 이루어진 구조에 의해 달성된다. 3 to 4, a plurality of fastening flanges 13 having bolt holes 12 drilled on the outer circumferential surface of the flow pipe 4 constituting the expansion pipe 7 are installed at regular intervals. The fastening flange 13 together with (7) is achieved by the structure consisting of the structure which is fastened to the pipe line A as the bolt 14 and the nut 15.

즉, 신축관(7)의 유동플랜지(5)가 하나의 볼트로서 가압링(11)과 밸브본체(3)와 함께 관로(A)에 일체로 체결 고정되어 신축관(7)이 밸브본체(3)의 내경 안에서 습동되지 못하였던 종래의 벨로우즈형 신축밸브와 달리, 신축관(7)이 관로(A)에만 체결 고정되는 구조에 의한 것이다. 여기서 가압링(11)은 다른 볼트(9)와 너트(10)로서 밸브본체(3)의 접속플랜지(1)에 체결 고정된다. That is, the flow flange 5 of the expansion pipe 7 is integrally fastened and fixed to the pipe line A together with the pressure ring 11 and the valve body 3 as one bolt, so that the expansion pipe 7 is the valve body ( Unlike the conventional bellows type expansion valve which could not slide within the inner diameter of 3), the expansion pipe 7 is fastened and fixed only to the pipeline A. Here, the pressure ring 11 is fastened and fixed to the connecting flange 1 of the valve body 3 as another bolt 9 and a nut 10.

따라서 신축관(7)의 유동관(4)은 상기 체결플랜지(13)와 가압링(11)의 사이 간격 만큼 밸브본체(3)의 내경 안에서 유체의 흐름방향으로 자유롭게 습동됨으로써, 관로의 팽창 및 수축현상이 발생될 때 신축관(7)은 본래의 신축력을 제대로 발휘할 수 있게 된다. Therefore, the flow pipe 4 of the expansion pipe 7 is free to slide in the flow direction of the fluid within the inner diameter of the valve body 3 by the distance between the fastening flange 13 and the pressure ring 11, thereby expanding and contracting the pipe. When the phenomenon occurs, the expansion pipe (7) can properly exhibit the original stretching force.

이에 따라 밸브본체(3)와 신축관(7)의 사이에서 누수가 전혀 발생하지 않아 신축밸브(100)의 원활한 운전이 가능하게 됨으로써 관로(A)(B)를 통과하는 유체의 흐름을 원활하게 할 수 있게 된다. Accordingly, no leakage occurs between the valve body 3 and the expansion pipe 7 so that the expansion valve 100 can be smoothly operated to smoothly flow the fluid passing through the pipe lines A and B. You can do it.

그리고 본 발명은 벨로우즈(6)의 골과 산에 의해 유체의 와류를 방지할 수 이는 것도 특징이다. 이는 도 5에 도시된 바와 같이 벨로우즈(6)의 내측 골에 와류방지링(16)이 각각 삽입 설치된 구조에 의해 달성된다. In addition, the present invention is characterized in that the vortex of the fluid can be prevented by the valleys and the acid of the bellows (6). This is achieved by the structure in which the vortex prevention rings 16 are respectively inserted in the inner valley of the bellows 6 as shown in FIG.

따라서 와류방지링(16)이 벨로우즈(6)의 내측 골을 막아주는 역할을 하여 벨로우즈(6)의 내측 골에 의해 발생되는 와류 및 와류에 의한 맥동파를 방지할 수 있게 된다. Therefore, the vortex prevention ring 16 serves to prevent the inner valley of the bellows 6 to prevent the pulsation wave caused by the vortex and the vortex generated by the inner valley of the bellows 6.

이에 따라 밸브 및 관로의 손상을 방지할 수 있게 된다. 이때 벨로우즈(6)의 신축에 영향을 주지 않도록 탄성이 있는 고무재질의 와류방지링(16)을 설치함이 바람직하다. Accordingly, it is possible to prevent damage to the valve and the pipe. At this time, it is preferable to install an elastic rubber vortex prevention ring 16 so as not to affect the expansion and contraction of the bellows (6).

또한, 본 발명은 벨로우즈(6)가 유체의 압력에 충분히 견딜 수 있는 것도 특징이다. 이는 도 5에 도시된 바와 같이 벨로우즈(6)의 외측 골에 보강링(17)이 각각 설치된 구조에 의해 가능하다. The present invention is also characterized in that the bellows 6 can withstand the pressure of the fluid sufficiently. This is possible by the structure in which the reinforcing rings 17 are respectively installed on the outer valley of the bellows 6 as shown in FIG. 5.

따라서 보강링(17)이 벨로우즈(6)의 외측 골을 외측에서 압지하는 역할을 하여 유체의 압력에 의해 벨로우즈(6)를 외경방향으로 확관되는 것을 방지할 수 있게 된다. Therefore, the reinforcing ring 17 serves to press the outer valley of the bellows 6 from the outside to prevent the bellows 6 from being expanded in the outer diameter direction by the pressure of the fluid.

이에 따라 벨로우즈(6)의 확관으로 인해 그 내측 골을 더욱 더 깊게 만들어 유체의 흐름을 방해하고 와류와 맥동파를 더욱 커지게 하는 현상을 방지할 수 있게 된다. 이때 보강링(17)은 벨로우즈(6)의 외측 골을 견고하게 지지할 수 있도록 금속재질로 구성함이 바람직하다.
Accordingly, due to the expansion of the bellows 6, the inner valleys can be made deeper to prevent the phenomenon of disturbing the flow of the fluid and increasing the vortex and the pulsating wave. At this time, the reinforcing ring 17 is preferably composed of a metal material so as to firmly support the outer valley of the bellows (6).
