본 고안은 왕복동식 압축기의 밸브구조에 관한 것으로, 특히 압축기의 흡입, 토출시의 동압을 이용하여 밸브의 움직임을 부드럽게 함으로써 밸브손실을 감소시키는 왕복동식 압축기의 밸브구조에 관한 것이다.The present invention relates to a valve structure of a reciprocating compressor, and more particularly, to a valve structure of a reciprocating compressor that reduces valve loss by smoothing the movement of the valve by using dynamic pressure during suction and discharge of the compressor.
종래의 왕복동식 압축기에 사용되는 밸브구조는, 제1도에 도시된 바와 같이 흡입밸브(1)와 밸브시트(2) 및 토출밸브(4)가 실린더(3)와 헤드커버(6) 사이에 설치되어 상기 실린더(3) 내의 압력과 상기 헤드커버(6) 내의 압력차이에 의해 개폐작용을 하도록 구성되었다.The valve structure used in the conventional reciprocating compressor has a suction valve 1, a valve seat 2 and a discharge valve 4 between the cylinder 3 and the head cover 6 as shown in FIG. And configured to open and close by pressure difference in the cylinder 3 and pressure in the head cover 6.
상기 흡입밸브(1)는 강(steel)으로 제작되어 리드(reed)형으로 환형을 갖고, 상기 밸브시트(2)는 흡입포트(7)와 토출포트(8)를 갖는다.The intake valve 1 is made of steel and has an annular shape in a reed type, and the valve seat 2 has a suction port 7 and a discharge port 8.
한편, 상기 토출밸브(4)는 상기 밸브시트(2)상에 조립되고, 상기 헤드커버(6)에는 작동유체가 통과되고 토출파이프 및 흡입파이프(도시되지 않음)가 연결된다.On the other hand, the discharge valve 4 is assembled on the valve seat 2, the working fluid is passed through the head cover 6, the discharge pipe and the suction pipe (not shown) is connected.
왕복동식 압축기의 흡입과정시, 상기 헤드커버(6)내의 흡입플래넘과 실린더 내의 압력차이에 의해 흡입밸브(1)가 열려 작동유체가 흡입포트(7)를 통해 실린더(3)내로 흡입된다.During the suction process of the reciprocating compressor, the suction valve 1 is opened by the pressure difference between the suction plenum in the head cover 6 and the cylinder, and the working fluid is sucked into the cylinder 3 through the suction port 7.
한편, 토출과정시, 압축과정을 거쳐 압축된 실린더(3)내의 작동유체의 압력이 상기 헤드 커버(6)내의 토출플래넘내의 압력보다 커져 토출밸브(4)가 열려 작동유체가 토출포트(8)를 통해 토출된다.On the other hand, during the discharging process, the pressure of the working fluid in the cylinder 3 compressed through the compression process is greater than the pressure in the discharging plenum in the head cover 6, so that the discharge valve 4 is opened, and the working fluid is discharged from the discharge port 8. Is discharged through).
이러한 종래의 왕복동식 압축기의 밸브구조에서는 밸브 주위의 압력차와 밸브의 강성에 의해 개폐가 이루어지므로 밸브자체의 강성에 의해 개폐에 영향을 받아 밸브유동손실이 발생되는 문제점이 있다.In the valve structure of such a conventional reciprocating compressor, the opening and closing is performed by the pressure difference around the valve and the rigidity of the valve, so that the valve flow loss is generated by being affected by the opening and closing by the rigidity of the valve itself.
따라서 본 고안은 이러한 종래 기술의 문제점을 해결하기 위한 것으로, 압축기의 흡입, 토출시 작동유체의 유동에 의해 발생되는 차압을 이용한 벨로우즈타입의 밸브에 의해 밸브유동손실의 저감할 수 있는 왕복동식 압축기의 밸브구조의 제공을 목적으로 한 것으로서, 실린더와 헤드커버사이에 설치되어 상기 실린더와 헤드커버를 연통시키는 흡입포트 및 토출포트를 갖는 밸브시트와, 상기 헤드커버의 토출부와 연결된 토출파이프에서 분지되어 상기 토출부를 관통하는 토출분지 파이프와, 상기 토출분지 파이프와 연결된 한편 상기 토출포트의 형상과 대응하는 형상을 갖는 덮개와 상기 토출분지파이프와 덮개를 연결하는 신축성 주름관을 갖는 토출벨로우즈를 구비한 왕복동식 압축기의 밸브구조를 제공함으로써 달성된다.Accordingly, the present invention is to solve the problems of the prior art, a reciprocating compressor that can reduce the valve flow loss by the bellows-type valve using the differential pressure generated by the flow of the working fluid during the suction and discharge of the compressor.

제2도에 도시된 바와 같이 밸브구조는 헤드커버(10)와 실린더(20) 사이에 설치된 밸브 시트(30)와, 상기 헤드커버(10)에 연결된 토출파이프(40)에서 분지된 토출분지파이프(41)와 상기 토출분지파이프(41)와 연통된 토출벨로우즈(60)와 상기 헤드커버(10)에 연결된 흡입파이프(50)와 연결되지 않고 다른 흡입측(흡입쉘 등)과 연결된 흡입분지파이프(51)와 연통된 흡입벨로우즈(70)로 구성된다.As shown in FIG. 2, the valve structure includes a valve seat 30 provided between the head cover 10 and the cylinder 20, and a discharge branch pipe branched from the discharge pipe 40 connected to the head cover 10. A suction branch pipe connected to the other suction side (suction shell, etc.), not connected to the discharge bellows 60 connected to the discharge branch pipe 41 and the suction pipe 50 connected to the head cover 10, and the discharge branch pipe 41. And a suction bellows 70 in communication with 51.
상기 밸브시트(30)는 헤드커버(10)의 토출부(11)와 실린더(20)를 연통시키는 토출포트(31), 헤드커버(10)의 흡입부(12)와 실린더(20)를 연통시키는 흡입포트(32)를 갖는다.The valve seat 30 communicates the discharge port 31 for communicating the discharge part 11 of the head cover 10 with the cylinder 20, and the suction part 12 of the head cover 10 and the cylinder 20. It has a suction port (32).

또한 토출파이프(40)에서 분지된 토출분지파이프(41)는 상기 헤드커버(10)의 토출부(11)에 연결되고, 상기 흡입분지파이프(51)는 상기 헤드커버(10)의 흡입부(12)에 연결된다.In addition, the discharge branch pipe 41 branched from the discharge pipe 40 is connected to the discharge portion 11 of the head cover 10, the suction branch pipe 51 is the suction portion of the head cover 10 ( 12).
상기 토출벨로우즈(60)는 상기 토출분지파이프(41)와 연통된 신축성 주름관(62)과 상기 주름관(62) 단부에 연통된 한편 상기 밸브시트(30)의 토출포트(31)의 형상과 대응되는 형상을 갖는 덮개(61)를 갖는다.The discharge bellows 60 communicates with the flexible corrugated pipe 62 communicating with the discharge branch pipe 41 and the end of the corrugated pipe 62, and corresponds to the shape of the discharge port 31 of the valve seat 30.

이하, 제3도 및 제4도를 참조하여 상기 실시예의 작용을 설명한다.Hereinafter, the operation of the embodiment will be described with reference to FIGS. 3 and 4.
압축기의 압축과정중 토출파이프(40), 토출분지파이프(41) 및 토출부(11)에서는 작동유체의 유동은 없으며 이때 압력을 Pd, 실린더(20)의 압력을 Pc라 할 때 PdPc의 상태에서 토출포트(31)는 토출벨로우즈(60)에 의해 막혀 있다(제3a도 참조).There is no flow of working fluid in the discharge pipe 40, the discharge branch pipe 41, and the discharge part 11 during the compression process of the compressor. At this time, when the pressure is Pd and the pressure of the cylinder 20 is Pc, The discharge port 31 is blocked by the discharge bellows 60 (see also FIG. 3A).
한편 압축과정이 계속되어 실린더의 압력 Pc가 Pd보다 커지기 시작하여 토출포트(31)이 열리기 시작하면 토출파이프(40)내에 작동유체의 유동이 발생되어 베르누이정리에 따라, 토출파이프(40) 내의 압력은 토출분지파이프(41) 내의 압력 Pd보다 낮아지게 된다.On the other hand, when the compression process continues and the pressure Pc of the cylinder starts to be larger than Pd, and the discharge port 31 starts to open, a flow of working fluid is generated in the discharge pipe 40, and according to Bernoulli's theorem, the pressure in the discharge pipe 40 Is lower than the pressure Pd in the discharge branch pipe 41.
따라서, 토출분지파이프(41)와 연통된 토출벨로우즈(60) 내의 유체가 토출파이프(40)쪽으로 유동되어 역시 압력이 낮아지게 되어, 토출포트(31)의 열림이 빨라지게 된다.Therefore, the fluid in the discharge bellows 60 in communication with the discharge branch pipe 41 flows toward the discharge pipe 40, which also lowers the pressure, so that the opening of the discharge port 31 is accelerated.
즉, 토출벨로우즈(60)의 들림이 빨라지게 된다(제3b도 참조).That is, the lifting of the discharge bellows 60 becomes faster (see also 3b).
토출이 종료될 무렵이면 토출파이프(40)내의 유동속도가 낮아져 토출벨로우즈(60)내의 압력이 증가하면서 토출포트(31)를 막게 된다.At the end of the discharge, the flow rate in the discharge pipe 40 is lowered, thereby increasing the pressure in the discharge bellows 60 to block the discharge port 31.
한편, 압축기의 흡입과정중 실린더(20) 내의 압력(Pc)이 흡입벨로우즈(70)의 압력보다 더 낮아지게 되면 흡입포트(32)가 열리고 작동유체가 실린더(20) 내로 흡입된다.On the other hand, if the pressure Pc in the cylinder 20 becomes lower than the pressure of the suction bellows 70 during the suction process of the compressor, the suction port 32 is opened and the working fluid is sucked into the cylinder 20.
한편 흡입파이프(50)에서 들어오는 유체의 압력(Ps)은 흡입쉘 등에 연결된 흡입분지파이프(51) 내의 압력(흡입벨로우즈(70)의 압력)보다 낮으므로, 흡입포트(32)는 더욱 쉽게 열리게 된다.Meanwhile, since the pressure Ps of the fluid coming from the suction pipe 50 is lower than the pressure in the suction branch pipe 51 connected to the suction shell or the like (pressure of the suction bellows 70), the suction port 32 is more easily opened. .
흡입과정이 종료될 무렵에는 흡입파이프(50)내의 압력이 회복되면서 흡입포트(32)는 흡입벨로우즈(70)에 의해 닫히게 된다.At the end of the suction process, the pressure in the suction pipe 50 is restored and the suction port 32 is closed by the suction bellows 70.
이상 설명한 바와 같이 본 고안에 따르면 밸브개폐시의 유체의 유동에 의해 발생되는 압력차에 의해 밸브의 개폐작용이 원활히 이루어짐으로서 밸브에 의한 유동손실을 저감할 수 있다.As described above, according to the present invention, the flow loss due to the valve can be reduced by smoothly opening and closing the valve by the pressure difference generated by the flow of the fluid at the time of opening and closing the valve.
