Abstract

PURPOSE: A butterfly valve is provided to minimize the abrasion of an expansion sheet and to improve the sealing property by combining the expansion sheet to the circumference of an on/off unit. CONSTITUTION: A butterfly valve is operated by the steps of: avoiding the contact of an on/off unit with a valve body(10) by revolving the on/off unit as air is removed from an air chamber(52) of an expansion sheet(50) when desiring to close a butterfly valve; forcibly feeding air to an air hole(21) on the lower part of a rotary shaft(20); feeding the introduced air into the air hole to a channel hole(43) of a combining ring body(40) through an air exhaust port(22); filling the air chamber of the expansion sheet with the introduced air to the channel port; and interrupting the flow of sludge by closely adhering the air to the inner circumference of the valve body(10). The butterfly valve can extend the life span of the expansion sheet by preventing the sheet from being worn away.

Description

버터플라이 밸브{Butterfly valve}Butterfly Valve

본 발명은 버터플라이 밸브에 관한 것으로서, 더욱 상세하게는 개폐수단의 원주면을 따라 팽창시트를 설치하므로서 팽창시트의 마모를 극소화함은 물론이고, 밀폐성을 크게 향상시킨 버터플라이 밸브에 관한 것이다.The present invention relates to a butterfly valve, and more particularly, to a butterfly valve that not only minimizes wear of the expansion seat but also greatly improves sealing property by providing an expansion seat along the circumferential surface of the opening and closing means.

일반적으로, 공급관 사이에 설치되어 분말 또는 슬러지 등의 유통을 제어하는 버터플라이 밸브는 도 1과 같이 링상의 밸브 몸체(1) 내주연에 외부로부터 공급된 에어에 의해 신축되는 팽창시트(2)가 설치되고, 상기 밸브 몸체(1)의 내부에 회전축(3)이 수직으로 관통 설치되며, 상기 회전축(3)에 밸브 몸체(1)의 내부를 개폐시킬 수 있는 원판형상의 개폐수단(4)이 설치된다.In general, a butterfly valve installed between supply pipes to control the flow of powder or sludge or the like has an expansion seat 2 that is expanded and contracted by air supplied from the outside at the inner circumference of the ring-shaped valve body 1 as shown in FIG. Is installed, the rotary shaft 3 is vertically penetrated inside the valve body 1, the disk-shaped opening and closing means (4) capable of opening and closing the interior of the valve body (1) to the rotary shaft (3) Is installed.

그러나, 상기와 같이 구성된 종래의 버터플라이 밸브는 도 1의 (a)와 같이 회전축(3)이 팽창시트(2)를 관통하여 회전축(3)과 팽창시트(2)간에 마찰이 발생하기 때문에 회전축(3)과 팽창시트(2) 사이의 마모가 발생할 시 이들 사이의 간극으로 에어가 누설되므로서 개폐수단(4)과 팽창시트(2)의 사이가 이격되어 분말의 누설을 초래하는 등의 많은 문제점이 있었다.However, in the conventional butterfly valve configured as described above, since the rotating shaft 3 passes through the expansion seat 2 as shown in FIG. 1A, friction occurs between the rotating shaft 3 and the expansion seat 2. When abrasion between (3) and the expansion sheet (2) occurs, air leaks into the gap between them, so that the space between the opening and closing means (4) and the expansion sheet (2) is separated, resulting in the leakage of powder. There was a problem.

따라서, 본 발명은 상기와 같은 문제점을 감안하여 창출한 것으로서, 개폐수단의 원주면에 팽창시트를 결합,설치하여 팽창시트의 마모를 극소화함은 물론이고, 밀폐성을 크게 향상시킨 버터플라이 밸브를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above problems, and provides a butterfly valve that combines and installs an expansion sheet on the circumferential surface of the opening and closing means to minimize wear of the expansion sheet, as well as greatly improve the sealing property. Has its purpose.

The air outlet 22 is formed.

그런 다음, 상기 회전축(20)에 원판형상의 개폐수단(30)을 결합설치하는데, 상기 개폐수단(30)의 일측 가장자리를 따라 결합홈(31)을 형성한다.Then, coupled to install the disc-shaped opening and closing means 30 to the rotating shaft 20, the coupling groove 31 is formed along one side edge of the opening and closing means (30).

그리고, 상기 개폐수단(30)의 가장자리에 결합홈(31)과 대향되는 결합홈(41)을 가진 결합링체(40)를 다수의 보울트(42)로 결합하는데, 상기 결합링체(40)의 적소에 회전축(20)의 에어배출구(22)와 연통되는 유로공(43)을 형성한다.In addition, the coupling ring body 40 having the coupling groove 41 opposite to the coupling groove 31 at the edge of the opening and closing means 30 is coupled to the plurality of bolts 42, where the coupling ring body 40 is appropriately positioned. A flow path hole 43 is formed in communication with the air discharge port 22 of the rotating shaft 20.

또한, 개폐수단(30)과 결합링체(40)의 사이에 팽창시트(50)를 설치하는데, 상기 팽창시트(50)의 양측 단부에 끼움부(51)를 형성한 다음, 상기 끼움부(51)를 개폐수단(30)의 결합홈(31)과 결합링체(40)의 결합홈(41)에 끼움결합하여 도 4와 같이 팽창시트(50)의 내부에 에어실(52)을 형성한다.In addition, the expansion sheet 50 is installed between the opening and closing means 30 and the coupling ring body 40, the fitting portion 51 is formed at both ends of the expansion sheet 50, and then the fitting portion 51 ) Is fitted into the coupling groove 31 of the opening and closing means 30 and the coupling groove 41 of the coupling ring body 40 to form an air chamber 52 inside the expansion sheet 50 as shown in FIG. 4.

한편, 도 5와 같이 회전축(20')과 편향되게 설치된 개폐수단(30')의 일측 외주부에 밸브 몸체(10')의 내주부와 대응되는 팽창시트(50')를 설치하여도 본 발명에 속한다.Meanwhile, even when the expansion seat 50 'corresponding to the inner circumference of the valve body 10' is installed at one outer circumference of the opening / closing means 30 'installed to be deflected with the rotation shaft 20' as shown in FIG. Belongs.

상기와 같이 구성된 버터플라이 밸브의 작용효과를 설명하면 다음과 같다.Referring to the effect of the butterfly valve configured as described above are as follows.

상기 버터플라이 밸브를 차단하고자 하면, 도 4의 (a)와 같이 팽창시트(50)의 에어실(52)에 에어가 제거된 상태에서 개폐수단(30)을 회전시켜 밸브몸체(10)와의 접촉을 회피한 다음, 회전축(20) 하단의 에어공(21)으로 소정압력의 에어를 강제 공급한다.When the butterfly valve is to be blocked, as shown in FIG. 4 (a), the opening and closing means 30 is rotated while the air is removed from the air chamber 52 of the expansion seat 50 so as to contact the valve body 10. Then, the air of a predetermined pressure is forcibly supplied to the air hole 21 at the lower end of the rotating shaft 20.

상기 에어공(21)으로 유입된 에어는 에어배출구(22)를 통해 결합링체(40)의 유로공(43)으로 공급되고, 상기 유로공(43)으로 공급된 에어는 팽창시트(50)의 에어실(52)로 충입되어 도 4의 (b)와 같이 팽창, 밸브 몸체(10)의 내주면에 밀착되므로서 분말이아 슬러지의 유통을 차단하게 된다.The air introduced into the air ball 21 is supplied to the flow path hole 43 of the coupling ring body 40 through the air discharge port 22, the air supplied to the flow path hole 43 of the expansion sheet 50 Filled into the air chamber 52 is expanded and close to the inner circumferential surface of the valve body 10 as shown in (b) of FIG. 4 to block the flow of the sludge powder.

이때, 상기 팽창시트(50)의 회전시 밸브몸체(10)와 전혀 접촉이 되지 않을 뿐만 아니라, 팽창시트(50)와 회전축(20)의 접촉이 없기 때문에 팽창시트(50)의 마모가 없어 이의 수명을 최대한 연장할 수 있다.At this time, not only the contact with the valve body 10 at the time of rotation of the expansion seat 50, but also because there is no contact between the expansion seat 50 and the rotating shaft 20, there is no wear of the expansion seat 50 It can extend the life as much as possible.

따라서, 본 발명은 개폐수단(30)의 원주면에 팽창시트(50)를 결합,설치하여 팽창시트(50)가 밸브몸체(10)와 접촉없이 회전되도록 하여 팽창시트(50)의 마모를 극소화하여 이의 수명을 최대한 연장함은 물론, 회전축(20)을 통해 팽창시트(50)의 에어실(52)로 에어가 공급되기 때문에 회전축(20)과 팽창시트(50)의 마찰로 인한 에어의 누설을 완벽하게 방지하므로서 탱창시트(50)의 동작불량으로 발생할 수 있는 분말의 누설을 최대한 방지할 수 있는 매우 유용한 효과가 있다.Therefore, in the present invention, the expansion seat 50 is coupled to and installed on the circumferential surface of the opening and closing means 30 so that the expansion seat 50 is rotated without contact with the valve body 10 to minimize wear of the expansion seat 50. By extending the life thereof as well as the air is supplied to the air chamber 52 of the expansion sheet 50 through the rotary shaft 20, leakage of air due to friction between the rotary shaft 20 and the expansion sheet 50 It is very useful to prevent the leakage of the powder that may occur as a malfunction of the tank sheet 50 while completely preventing the maximum.
