본 고안은 분무, 분사, 압출 또는 압축을 위한 고압펌프의 압력 자동 조절밸브에 관한 것으로 일을할때(분사, 압축등)는 정격 고압이 토출되고 일을 하지 않을 때(펌프 가동중)는 펌프 내의 고압이 “0”으로 떨어져 동력 장치에 부하가 걸리지 않게 하므로서 기계적 마모와 불필요한 에너지 소모를 감소시켜 경제성과 작업능율을 효율적으로 향상시키는데 그 목적이 있다.The present invention relates to a pressure automatic control valve of a high pressure pump for spraying, spraying, extruding or compressing. When working (injection, compression, etc.), the rated high pressure is discharged and the pump is not working (when the pump is running). Its purpose is to reduce the mechanical wear and unnecessary energy consumption by effectively reducing the high pressure inside the load to 0, thereby improving economic efficiency and efficiency.
종래의 펌프는 일을 하지 않고 있는 동안에는 펌프 내에 과고압이 걸리게 된다. 이때 초과 고압은 안전밸브로 배출되게 장치되어 있는데 이와 같은 장치는 기히 정하여진 정격고압 보다 높은 과압이 발생할 때에 그 초과 분만이 배출되는 것이어서 펌프의 동력장치에는 항상 정격 고압이 부하 상태로 작용하므로 펌프의 동력은 항상 정격 고압을 충분히 이길수 있는 마력을 보유하여야 하였다.Conventional pumps are subject to overpressure in the pump while they are not working. At this time, the excess high pressure is discharged to the safety valve. When the overpressure occurs higher than the predetermined rated high pressure, only the excess is discharged, so the rated power is always applied to the power unit of the pump. The power must always have enough horsepower to withstand the rated high pressure.
따라서 종래의 고압펌프는 높은 마력의 동력기를 사용하여야 하므로 연료 소모가 많고, 동력장치 마손율이 높아 비경제적이었다.Therefore, the conventional high-pressure pump has to use a high horsepower motor, high fuel consumption, high power equipment wear rate was uneconomical.
본 고안에서는 이와 같은 종래의 결점을 해결하기 위하여 압력을 토출시켜 일을 할 때에는 정격 고압의 토출되게 하고 토출을 중지시켰을 때에는 순간적으로 내압이 피스틴을 하강시키면 그 하단이 볼형 체그밸브를 열어 내압이 배출되어 내압이 “0”으로 떨어지게 한 것이다. 따라서 펌프의 동력장치에는 펌프의 압력으로 인한 부하가 걸리지 않게 안출하였다. 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In the present invention, in order to solve the above-mentioned drawbacks, the pressure is discharged so that the rated high pressure is discharged when the work is performed. The internal pressure dropped to zero. Therefore, the power unit of the pump was placed so as not to be loaded by the pressure of the pump. This will be described in detail with reference to the accompanying drawings.
압유입구(1')가 형성된 밸브동체(1) 중앙에 승강실(2) 내에 피스턴(3)을 장착하여 상부측(3a)은 외부에서 스프링(4)을 걸어 상부로 탄발되게 하고 하단부 축(3a)은 압배출구(5a)의 볼형 첵크밸브(6) 상단중앙에 접하도록 하며 압배출밸브실(5) 상부에는 압배출통로(7)를 형성하고 압배출밸브실(5) 일측에는 게이지(8)와 수동식 개폐밸브(9)를 착설하고 타측에는 볼밸브(10)로 토출구(11a)가 있는 압토출밸브실(11 )을 형성하되 그 내부로 부터 피스턴(3) 상부의 압유입실(2a)까지는 피스턴 작동을 위한 압공급통로(12)를 형성하여 압공급시 피스턴(3)이 하강하여 볼형첵크밸브(6)를 열도록 한 것이다.The piston 3 is mounted in the hoisting chamber 2 at the center of the valve body 1 in which the pressure inlet 1 'is formed. 3a) is in contact with the center of the upper end of the ball-shaped check valve (6) of the pressure discharge port (5a), forming a pressure discharge passage (7) on the upper side of the pressure discharge valve chamber (5) and a gauge ( 8) and the manual on-off valve 9 are installed, and on the other side, a pressure discharge valve chamber 11 having a discharge port 11a is formed as a ball valve 10 from the inside of the pressure inlet chamber of the upper part of the piston 3; 2a) is to form a pressure supply passage 12 for the piston operation so that the piston 3 when the pressure supply is lowered to open the ball-type check valve (6).
도면 중 미설 부호 5b는 게이지(8)로 압이 작용될수 있는 압유통구, 5c는 압토출밸브실(11)과 연통된 연통구, 6a, 10a는 밸브스프링, 13은 실시상태 설명을 위한 분사기의 개폐 밸브의 예시이다.In the figure, 5b is a pressure port for pressure acting on the gauge 8, 5c is a communication port in communication with the pressure discharge valve chamber 11, 6a, 10a is a valve spring, 13 is an injector for explaining the embodiment Is an example of an on / off valve.
이상과 같은 본 고안의 사용은 통상의 방법에 따라 고압펌프의 압 토출관을 압유입구(1')에 연결하여 압토출구(11a) 쪽을 거쳐 각종 분사기로 배출되게 되는데 시동시에는 내부가밀폐된 상태이므로 수동식 개폐밸브(9)를 열어 시동을 걸어준다.The use of the present invention as described above is connected to the pressure inlet (1 ') of the high pressure pump by the conventional method to be discharged to the various injectors through the pressure inlet (11a) side, the internally sealed at the start Open the manual shut-off valve (9) to start the state.
시동후에는 개폐밸브(9)를 잠근후 통상의 방법에 따라 분사기 개폐밸브(13)를 열고 분사하게 되는데 분사 작업도중 작업중지를 위하여 분사기 개페밸브(13)를 잠그어 주면 내압은 순간적으로 압공급통로(12)를 거쳐 피스턴(3) 상부의 압유입실(2a)에 공급되어 피스턴(3)을 하강시키며 그 하부 축(3a)은 볼형첵크밸브(6)를 밀어 압배출구(5a)를 열어 줌으로서 내부고압을 압배출통로(7)로 배출되어 순간적으로 압을 “0”으로 떨어진다.After starting, the on / off valve (9) is closed and then the injector on / off valve (13) is opened and sprayed according to the usual method. It is supplied to the pressure inlet chamber 2a on the upper part of the piston 3 through the passage 12 to lower the piston 3, and the lower shaft 3a pushes the ball type check valve 6 to open the pressure discharge port 5a. By zooming, the internal high pressure is discharged to the pressure discharge passage 7, and the pressure is momentarily dropped to "0".
이때 압토출밸브실(11)의 볼밸브(10)는 스프링(10a)에 의해 연통구(5c)를 막고 내압은 계속하여 압배출통로(7)를토 배출되어 펌프의 동력장치에는 압에 의한 부하가 전연 걸리지않게 된다.At this time, the ball valve 10 of the pressure discharge valve chamber 11 blocks the communication port 5c by the spring 10a, and the internal pressure continues to discharge the pressure discharge passage 7 to load the pump by the pressure. Will not take the lead.
재차 분사작업을 하기 위하여 분사기 개폐밸브(13)를 열어 주면 배출압이 떨어져 피스턴(3)은 스프링(4)에 의해 상승하고 첵크밸브(6)도 스프링(6a)에 의해 상승하여 압배출구(5a)를 막고 압토출구(11a) 쪽으로만 토출되며 이와 같은 동작은 순간적으로 이루어진다.When the injector opening / closing valve 13 is opened to perform the spraying operation again, the discharge pressure drops, the piston 3 rises by the spring 4, the check valve 6 also rises by the spring 6a, and the pressure discharge port 5a. ) And is discharged only toward the pressure discharge outlet 11a, and this operation is instantaneously performed.
본고안은 이와 같은 작용이므로 일을 하지 않을 때는 내압이 “0”으로 되어 펌프의 동력장치에 부하가 걸리지 않으므로 동력 에너지의 소모를 줄이며 동력 기계 수명을 연장하여 경제적인 효과가 있다.As this work is the same, the internal pressure becomes “0” when not working, so that the power unit of the pump is not loaded, thereby reducing the consumption of power energy and extending the power machine life, thereby having an economic effect.
