이하, 본 고안에 따른 바람직한 실시 예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail as follows.

도 3은 본 고안의 일 실시예에 따른 플랜지형 스윙체크밸브(100)의 단면을 도시한 것이다. 본 발명의 플랜지형 스윙체크밸브(100)는 복수개의 나사구멍(101a)을 갖는 바디(101), 복수개의 나사부재(102a)로 장착되는 상부커버(102), 유체의 유입공(109) 및 출구공(110)를 포함하는 외형을 가지며, 내부에는 일단이 힌지핀(107)에 힌지작동 가능하도록 연결된 로드(105), 로드(105)의 타단에 고정너트(106)에 의해 고정된 디스크(103), 유입공(109)의 내부쪽 단부에 부설된 시트링(104), 시트링(104)과 접하는 디스크(103)의 접합면에 부설된 탄성부재(108), 출구공(110) 상부쪽의 바디(101)에 접촉하는 디스크(103)의 바디(101) 접촉부에 부설된 완충부(112), 및 완충부의 결합수단(111)으로서 원형의 핀을 포함하여 구성된다.3 is a cross-sectional view of the flanged swing check valve 100 according to an embodiment of the present invention. The flanged swing check valve 100 of the present invention includes a body 101 having a plurality of screw holes 101a, an upper cover 102 mounted with a plurality of screw members 102a, an inlet hole 109 and a fluid. A disc having an outer shape including an outlet hole 110 and having a rod 105 connected to the hinge pin 107 so as to be hinged therein, and a disk fixed to the other end of the rod 105 by a fixing nut 106. 103), the seat ring 104 attached to the inner end of the inlet hole 109, the elastic member 108, and the outlet hole 110 disposed on the joint surface of the disk 103 in contact with the seat ring 104. The shock absorbing part 112 attached to the contact part of the body 101 of the disc 103 which contacts the side body 101, and the engaging means 111 of the shock absorbing part are comprised, including a circular pin.

이하에서 본 고안의 플랜지형 스윙체크밸브(100)의 작동에 대하여 설명한다. 유체가 유입공(109)을 통하여 유입되면 로드(105)가 상부쪽으로 힌지작동하고 이에따라 디스크(103)가 시트링(104)으로부터 분리되면서 스윙체크밸브가 오픈된다. 이때 유체가 많은 유량과 큰 압력으로 유입되는 경우 종래의 플랜지형 스윙체크밸브(도 2, 100)는 디스크(103)가 바디(101)에 끼는 경우가 발생하나, 본 발명의 플랜지형 스윙체크밸브(100)는 디스크(103)의 바디(101) 접촉부에 부설된 완충부(112)가 충격을 흡수하기 때문에 디스크(103)가 바디(101)에 끼는 경우가 발생하지 않고, 장기간 열려 있는 경우에도 부식으로 디스크(103)와 바디(101)가 융착되는 문제가 발생하지 않는다.Hereinafter will be described the operation of the flange-type swing check valve 100 of the present invention. When the fluid is introduced through the inlet hole 109, the rod 105 is hinged upwards and accordingly the disc 103 is separated from the seat ring 104 to open the swing check valve. In this case, when the fluid is introduced at a large flow rate and a large pressure, the conventional flange type swing check valve (FIGS. 2 and 100) may occur when the disc 103 is fitted to the body 101, but the flange type swing check valve of the present invention. 100 does not occur when the disc 103 is caught in the body 101 because the buffer 112 placed at the contact portion of the body 101 of the disc 103 absorbs the shock, and even when it is open for a long time. Corrosion does not cause a problem that the disk 103 and the body 101 is fused.
