Abstract

PURPOSE: A wedge-shaped body structure of a butterfly valve is provided to be used as a valve for high-temperature and high-pressure valve because the butterfly valve is composed of a wedge-shaped body and a main body. CONSTITUTION: A wedge-shaped body structure of a butterfly valve comprises a main body (10) and a wedge-shaped body (20). The main body has an inner inclined surface. The wedge-shaped body has a lower inclined surface (21). Bolts (30) penetrate through the through holes (22) of a bonnet (23) and bolt holes (12) of the main body to couple the lower inclined surface of the wedge-shaped body to the inner inclined surface of the main body. A body seat formed inside of the wedge-shaped body is integrally coupled to the main body.

Description

버터플라이 밸브 쐐기형 바디의 구조{Wedge-shaped body structure of butterfly valves}Wedge-shaped body structure of butterfly valves

본 고안은 버터플라이 밸브 쐐기형 바디의 구조에 관한 것으로 보다 상세하게는 버터플라이 밸브를 사용하다가 바디시트가 마모 및 파손되었을 때 현장에서 신속하게 교체 및 수리 가능하도록 한 것이다.
The present invention is directed to the structure of the butterfly valve wedge body, and more specifically, the use of the butterfly valve to be able to quickly replace and repair in the field when the body seat is worn and broken.

종래의 버터플라이 밸브는 바디시트와 바디, 디스크를 핀 또는 볼트로 체결하여 고정하는 구조로 되어있어 고온 고압용 밸브로는 적합하지 않아 425℃, 638.3BAR(CLASS 2500)의 조건에서는 버터플라이 밸브를 사용하지 못하고 게이트 밸브 또는 글로버 밸브를 사용해 왔다.
Conventional butterfly valve is structured to fasten body seat, body and disc by pin or bolt, so it is not suitable for high temperature and high pressure valve. Therefore, butterfly valve cannot be operated under conditions of 425 ℃ and 638.3 BAR (CLASS 2500). It has not been used and gate valves or glover valves have been used.

상기와 같은 425℃, 638.3BAR(CLASS 2500)의 고온 고압의 조건에서 종래의 버터플라이 밸브를 사용할 경우에는 바디와 바디시트를 볼트로 체결을 하여 사용하면 볼트가 고압을 견디지 못하고 터져버려 기밀을 유지할 수가 없었을 뿐만 아니라 바디시트와 바디가 일체형으로 되어있는 경우에는 바다시트의 마모 및 파손에 따른 수리시 밸브 전체를 교체하거나 또는 밸브 전체를 분리하여 바디시트를 교체하여야 했으므로 협소한 공간에서는 작업이 어려웠을 뿐만 아니라 버터플라이 밸브를 분리하여 바디시트를 수리하거나 버터플라이 밸브 자체를 교체하는데 많은 비용과 수리시간이 소요되어왔다.
When using a conventional butterfly valve under the conditions of high temperature and high pressure of 425 ° C. and 638.3 BAR (CLASS 2500) as described above, when the body and the body seat are tightened with bolts, the bolts do not withstand high pressure and burst to maintain airtightness. In addition, when the body seat and the body were integrated, it was difficult to work in a narrow space because the entire valve or the body seat had to be replaced by removing the whole valve when repairing due to wear and damage of the sea seat. In addition, costly and time-consuming repairs have been required to remove the butterfly valve to repair the body seat or to replace the butterfly valve itself.

상기와 같은 문제점을 해결하기 위해 본 발명은 쐐기형 바디와 메인바디를 볼트없이 결합할 수 있도록 하고 메인바디와 쐐기형 바디가 구비된 보닛을 볼트로 체결하여 사용하는 것으로 수리 및 보수 유지가 용이하도록 한 것이다.
In order to solve the problems described above, the present invention allows the wedge-shaped body and the main body to be coupled without bolts, and is used by fastening the bonnet provided with the main body and the wedge-shaped body with bolts for easy repair and maintenance. It is.

이와 같이 된 본 고안은 고정되어 있는 볼트를 풀어내어 간단하고 신속하게 쐐기형 바디를 교체할 수가 있어 밸브 전체를 들어내거나 교체하는 번거로움이 없으며, 현장에서 바로 교체 및 수리가 가능하므로 수리시간 및 비용절감의 효과가 있을 뿐만 아니라 고온 고압용 밸브로 사용할 수 없었던 버터플라이 밸브를 쐐기형 바디와 메인 바디의 구성으로 형성하여 고온 고압용 밸브로도 사용할 수 있어 경제적인 효과가 있는 것이다.
In this way, it is possible to replace the wedge body simply and quickly by unscrewing the fixed bolts, so there is no hassle to lift or replace the entire valve. In addition to savings, the butterfly valve, which could not be used as a high temperature and high pressure valve, is formed in a wedge-shaped body and a main body, and thus can be used as a high temperature and high pressure valve.

도 2는 본 발명에 의한 버터플라이 밸브의 단면도1 is an exploded cross-sectional view of the wedge-shaped body and the main body according to the present invention
2 is a cross-sectional view of a butterfly valve according to the present invention

버터플라이 밸브(1)에 있어서,
In the butterfly valve 1,

메인바디(10)의 내측으로 경사면(11)을 형성하여 쐐기형 바디(20)의 하측 경사면(21)을 보닛(23)의 통공(22)과 메인 바디(10)의 볼트공(12)을 볼트(30)로 체결하여 사용할 수 있도록 한 것이다.
The inclined surface 11 is formed inside the main body 10 so that the lower inclined surface 21 of the wedge-shaped body 20 is connected to the through hole 22 of the bonnet 23 and the bolt hole 12 of the main body 10. It is to be used by fastening with a bolt (30).

이와 같이 된 본 발명을 첨부된 도면에 의해 상세히 설명하면 다음과 같다.
The present invention thus made will be described in detail with reference to the accompanying drawings.

버터플라이 밸브(1)를 형성함에 있어서, 메인 바디(10)의 경사면(11)으로 쐐기형 바디(20)이 경사면(21)이 닿도록 하여 기밀을 유지하고, 보닛(23)의 통공(22)과 메인 바디(10)의 볼트공(12)을 볼트(30)로 체결하여 사용하는 것으로,버터플라이 밸브(1)를 사용하다 보면 반복적인 작동에 의해 마찰이 생겨 메인 바디(10)와 쐐기형 바디(20)가 마모 및 파손이 되는 경우가 발생하게 되는데 이를 교체하기 위해 볼트(30)를 풀어 메인 바디(10)와 쐐기형 바디(20)를 분리하고 쐐기형 바디(20)를 수리 또는 교체하여 볼트(30)로 보닛(23)의 통공(22)과 메인 바디(10)의 볼트공(12)을 체결한 후 고정하여 신속하게 교체작업을 완료하면 되는 것이다.In forming the butterfly valve 1, the wedge-shaped body 20 is in contact with the inclined surface 11 on the inclined surface 11 of the main body 10 to maintain the airtightness, and the through hole 22 of the bonnet 23. The bolt hole 12 of the main body 10 and the bolt 30 are fastened by the bolt 30. When the butterfly valve 1 is used, friction occurs due to repetitive operation of the main body 10 and the wedge. When the body 20 is worn and damaged, the main body 10 and the wedge-shaped body 20 are separated by loosening the bolt 30 to replace or repair the wedge-shaped body 20. After replacing the bolt hole 12 of the bonnet 23 and the bolt hole 12 of the main body 10 by the bolt 30 is fixed to complete the replacement work quickly.
