Abstract

The present invention is characterized by installing a valve plate protector on an inlet side of a valve main body duct for preventing a valve plate of a butterfly valve from being damaged by friction with foreign substances mixed in a fluid. The valve plate is equipped inside the duct formed on the butterfly valve main body, and a rotation shaft is installed in the center of the valve plate to penetrate vertically for opening and closing the duct by rotating the valve plate 90 degrees with an opening and closing apparatus formed on the rotation shaft. The present invention is the valve plate protector of a butterfly valve, capable of preventing the outer circumferential surface portion of the valve plate from being damaged by friction with foreign substances such as mixed sand by allowing the center of duct, at which the opened valve when the valve opens the duct is located, to bend with a curvature corresponding to the outer circumferential surface of the valve plate, by forming a fixing portion attached to the flange of the valve main body on the upper and the lower ends, and by equipping with the valve plate protector installed at a preset interval with the outer circumference of the valve plate for preventing the fluid flowed in through the entrance of the duct from directly frictionizing the outer circumferential surface of the valve plate.

Description

버터플라이 밸브의 밸브판 보호구{Butterfly valve of the valve plate protective equipment}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a butterfly valve,

본 발명은 버터플라이 밸브의 밸브판이 유체에 혼합된 이물질과의 마찰에 의하여 손상되는 것을 방지할 수 있도록 밸브몸통 관로의 유입구측에 밸브판 보호구를 설치한 것에 특징이 있다.
The present invention is characterized in that a valve plate protector is provided on the inlet side of the valve body tube so as to prevent the valve plate of the butterfly valve from being damaged by friction with foreign matter mixed with the fluid.

종래의 버터플라이 밸브는 관로내에 관로를 개폐하는 밸브판을 장치하여 개폐함으로써, 유체를 제어하고 있으나 유체내에 혼합된 모래와 같은 이물질이 유체와 같이 밸브관로를 통과하면서 밸브판의 외주면을 손상시키기 때문에 밸브판의 수명이 짧아지고 밸브판의 외주연부가 손상된 만큼 실링부와의 밀착성이 저하되어 밸브작용의 정밀도가 떨어지게 되는 문제점이 있었다.
A conventional butterfly valve controls a fluid by opening and closing a valve plate that opens and closes a conduit in the conduit, but foreign substances such as sand mixed in the fluid pass through the valve conduit and damage the outer circumferential surface of the valve plate The life of the valve plate is shortened and the outer peripheral edge of the valve plate is damaged, so that the adhesion with the sealing portion is lowered and the precision of the valve action is lowered.

본 발명은 상기와 같은 종래의 결점을 해소하기 위하여 발명된 것이다.
SUMMARY OF THE INVENTION The present invention has been made in order to overcome the drawbacks of the prior art.

본 발명은 버터플라이 밸브 몸통에 형성되는 관로내에 밸브판을 장치하고, 밸브판의 중심에서 상하로 관통하는 회전축을 설치하여 회전축에 형성된 개폐장치로 밸브판을 90도 회전시켜 관로를 개폐하는 것에 있어서, 밸브판이 관로를 개방할때에 열려진 밸브판이 위치하는 관로중앙에 밸브판의 외주면에 대응하는 곡율을 가지고 휘어지며, 상하단에 밸브몸통의 플랜지에 부착되는 고정부가 형성되고, 밸브판외주와 일정간격을 두고 설치되는 밸브판 보호구를 장치하여 관로입구로 유입되는 유체가 밸브판의 외주면에 직접마찰되지 않도록 함으로써, 혼합된 모래와 같은 이물질에 의하여 밸브판의 외주연부가 손상되는 것을 예방할 수 있게 한 것이다.
The present invention is characterized in that a valve plate is provided in a pipeline formed in a butterfly valve body and a rotary shaft penetrating vertically through the center of the valve plate is provided so that the valve plate is rotated 90 degrees by an opening / And a fixing portion attached to the flange of the valve body is formed at the upper and lower ends of the valve plate, and a fixing portion attached to the flange of the valve body is formed at a central portion of the pipe plate at a position spaced from the outer periphery of the valve plate by a predetermined distance And prevents the fluid introduced into the pipe inlet from directly rubbing against the outer circumferential surface of the valve plate, thereby preventing the outer circumferential edge of the valve plate from being damaged by foreign substances such as mixed sand .

이와 같이 된 본 발명은 버터플라이밸브 몸통에 형성된 관로를 개방하여 관로입구측에서 출구쪽으로 유체가 지나갈 때 관로입구에서 유체와 만나는 밸브판의 외주를 밸브판 보호구가 커버하므로 고압으로 유입되는 유체에 의하여 밸브판의 외주연이 직접 마찰되는 것을 방지하게 되고, 이로인해 유체에 혼입된 모래와 같은 이물질이 밸브판의 외주연을 손상시키는 것을 예방하게 되어 밸브판을 보호하는 효과를 내게 되고, 이로인해 밸브판의 외주연이 심하게 손상되는 것을 막을 수 있어서 밸브판을 닫을 때 실링부와의 밀착을 유지하게 되어 폐쇄작용이 확고하게 되는 밸브를 얻을 수 있으며, 밸브판의 수명을 연장시킬 수 있어서 유지비용을 절감시킬 수 있는 이점을 얻는 것이다.In the present invention as described above, since the valve plate protector covers the outer circumference of the valve plate which meets the fluid at the inlet of the conduit when the conduit formed in the butterfly valve body is opened and the fluid passes from the inlet side to the outlet side, The outer circumference of the valve plate is prevented from being directly rubbed, thereby preventing the foreign substance such as sand mixed with the fluid from damaging the outer circumference of the valve plate, thereby protecting the valve plate, The outer periphery of the plate can be prevented from being severely damaged, so that the valve plate can be kept in close contact with the sealing portion when the valve plate is closed, so that the valve closing action can be obtained. It is possible to obtain an advantage that can be saved.

특히, 본 발명의 밸브판 보호구는 밸브몸통의 관로외주에 형성된 플랜지에 고정되어 접속되는 관체와 조립됨으로써, 확고한 고정이 이루어지고 곡면으로 된 보호판의 외주면이 뾰족돌출면으로 되어 관로로 유입되는 유체의 마찰을 분산시키기 때문에 유체의 흐름을 크게 방해하지 않는 이점이 있고, 곡면으로 된 보호판의 강도를 유지하여 밸브판의 외주연을 보호할 수 있도록 되며, 보호판 내면과 밸브판 사이가 10∼15mm 간격을 유지함으로써, 밸브판의 개폐를 방해하지 않으며, 회적의 보호기능을 발휘하게 되는 이점이 있어서 안전하게 발명의 목적을 달성하게 되는 효과가 있다.
Particularly, the valve plate protecting member of the present invention is assembled with a tube body fixedly connected to a flange formed on the outer circumference of the tube body of the valve body, thereby firmly fixing the tube body, and the outer circumferential surface of the curved protective plate has a sharp protruding surface, Since the friction is dispersed, there is an advantage that the flow of the fluid is not significantly disturbed, and the outer edge of the valve plate can be protected by maintaining the strength of the curved protection plate. The interval between the inner surface of the protection plate and the valve plate is 10-15 mm There is an advantage that the opening and closing of the valve plate is not hindered and the protection function of the valve is exhibited, and the object of the invention can be achieved safely.
