Description

감압변의 완충장치Buffer of pressure reducing valve

첨부도면은 본 고안의 완충장치를 설비한 감압변의 단면도이다.The accompanying drawings are sectional views of a pressure reducing valve equipped with a shock absorber of the present invention.

본 고안은 밸브 본체의 상부에 고정입설한 실린더내에 피스턴을 승강자재하게 설치한 감압변에 있어서, 그 피스턴과 실린더 사이에 형성된 에어챔버의 통기구에 기압 조정용 니이들 밸브를 설치하여 피스턴 승강 작동시의 충격을 방지하도록 한 감압변의 완충장치에 관한 것이다.The present invention is a pressure reducing valve in which a piston is lifted up and down in a cylinder fixedly placed on an upper part of a valve body, and a needle valve for adjusting pressure is provided at an air vent of an air chamber formed between the piston and the cylinder. It relates to a shock absorber of the pressure reducing valve to prevent the impact.

공지의 감압변에 있어서는 피스턴의 승강동작을 원활하게 하기 위하여 실린더벽에 통기구를 뚫어서 그 실린더와 피스턴 사이에 형성된 에어챔버 내의 공기가 외부와 소통되게 하였다. 그러나 이와 같은 구조의 감압변에 있어서는 밸브의 입구압력이 급격히 변화하는 경우 피스턴이 급격하게 상승하거나 하강하게 되고, 따라서 그 피스턴이 변좌에 충격을 가하게 하므로 피스턴의 저면에 착설한 라버실의 사용수명을 단축시키고, 또 그와 작은 충격에 의하여 변좌에 균열이 생기게 하거나 심지어는 파괴의 위험을 가져다 주는 문제점이 있었다.In the well-known pressure reducing valve, in order to facilitate the lifting operation of the piston, an air vent is formed in the cylinder wall to allow air in the air chamber formed between the cylinder and the piston to communicate with the outside. However, in the pressure reducing valve of such a structure, when the inlet pressure of the valve changes rapidly, the piston rises or falls sharply, thus causing the piston to impact on the toilet seat. There was a problem that the shortening and the small impact caused the crack in the toilet seat or even the risk of destruction.

본 고안은 이와 같은 문제점을 해소하고저 실린더와 피스턴 사이에 형성된 에어챔버내의 기압을 조정하기 위한 니이들밸브를 에어챔버의 통기구에 설치하여 이를 적당히 조절하므로서 에어챔버내의 공기소통속도를 조절하고 그러므로서 피스턴의 급격한 승강작동을 방지하여 밸브의 파손의 우려를 없게 하고 사용수명을 길게 할 수 있게 한 것인 바 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다. 밸브본체(1)의 상부에 고정입설하여 지지보울트(2)로 고정한 실린더(3) 내에 그 내경보다 외경이 작은 피스턴(4)을 내설하고, 실린더(3)의 하면과 피스턴(4)의 상면 주위에는 각각 패킹 그랜드(5)(6)를 착설하여 상기한 실린더(3)와 피스턴(4) 사이에 에어챔버(7)를 형성한 감압변에 있어서, 실린더(3)의 측벽에 천설한 통기구에 통상의 니이들 밸브(8)를 착설하여 에어챔버(7) 내의 공기가 소정량만큼 벤트(Vent) 작용되게 한 것이다.The present invention solves such a problem and installs a needle valve for adjusting the air pressure in the air chamber formed between the lower cylinder and the piston in the vent of the air chamber, thereby adjusting the air communication speed in the air chamber. Preventing the sudden lifting operation of the piston to avoid the risk of damage to the valve and to extend the service life of the bar will be described in detail by the accompanying drawings as follows. In the cylinder 3 fixedly installed on the upper part of the valve body 1 and fixed by the support bolt 2, a piston 4 having a smaller outer diameter than the inner diameter is embedded, and the lower surface of the cylinder 3 and the upper surface of the piston 4 In the pressure reducing valve in which the packing glands 5 and 6 are respectively installed and the air chamber 7 is formed between the cylinder 3 and the piston 4, the vent hole which is installed on the side wall of the cylinder 3, respectively. The conventional needle valve 8 is installed in the air chamber 7 so that the air in the air chamber 7 is vented by a predetermined amount.

도면 중 미설명부호(9)는 밸브의 입구(10)측의 유체압력이 바이패스관(11)을 통하여 실린더(3) 내의 감압실(12)로 진입할 때, 그 진입속도를 조정하기 위해 바이패스관(11)에 설치된 니이들밸브이고, (13)은 감압실(12)과 밸브의 출구(15)측간에 연설된 바이패스관(14)에 설치된 리규레이터이며, (16)은 변좌, (17)은 라버실이다.In the drawing, reference numeral 9 is used to adjust the entry speed when the fluid pressure on the inlet 10 side of the valve enters the decompression chamber 12 in the cylinder 3 through the bypass pipe 11. It is a needle valve installed in the bypass pipe (11), (13) is a regulator provided in the bypass pipe (14) extended between the decompression chamber (12) and the outlet (15) side of the valve, and (16) is a toilet seat. , (17) is a laboratory.

이와 같이 구성된 본 고안은 입구(10)측의 유체 압력과 감압실(12) 내의 압력의 차이로 인하여 피스턴(4)이 승강작동하여 변좌(16)를 폐쇄하거나 개방하게 되는데 이 때에 피스턴(4)의 승강작동에 따라 에어챔버(7)의 용적이 변화하고 따라서 에어챔버(7) 내부의 공기가 통기구에 설치된 니이들밸브(8)를 걸쳐 외부로 배출되거나 외기가 흡입된다. 그러므로 니이들밸브(8)의 개폐도를 조절하면 에어챔버(7) 내의 공기소통속도를 조절할 수 있게 되고 피스턴(4)의 승강속도를 완만하게 조절할 수 있게 되는 것이다.According to the present invention configured as described above, the piston 4 moves up and down to close or open the toilet seat 16 due to the difference between the fluid pressure on the inlet 10 side and the pressure in the decompression chamber 12. The volume of the air chamber 7 changes according to the lifting operation of the air chamber, so that the air inside the air chamber 7 is discharged to the outside through the needle valve 8 installed in the air vent or outside air is sucked in. Therefore, by adjusting the opening and closing degree of the needle valve (8) it is possible to adjust the air communication speed in the air chamber (7) and to smoothly adjust the lifting speed of the piston (4).

이와 같이 본 고안은 실린더(3)와 피스턴(4)간에 형성된 에어챔버(7)의 통기구에 니이들밸브(8)를 착설하여 에어챔버(7)의 공기의 흡입 또는 배출속도를 소정치로 조절함에 따라 피스턴(4)의 작동완화로 밸브의 개폐작동시나 또는 밸브입구측의 유체압이 급격히 변화하여도 피스턴은 항시 완만하게 작동하게 되어 변좌(16)에 가해지기 쉬운 충격을 덜어 밸브의 파손을 방지하고 사용수명을 길게 할 수 있는 효과가 있다.As such, the present invention installs the needle valve 8 in the vent of the air chamber 7 formed between the cylinder 3 and the piston 4 to adjust the intake or discharge speed of air in the air chamber 7 to a predetermined value. Therefore, even when the opening and closing operation of the valve or the fluid pressure at the valve inlet side change abruptly due to the deactivation of the piston 4, the piston is always operated smoothly to reduce the damage of the valve by reducing the shock that is easily applied to the toilet seat 16 It has the effect of preventing long life.
