Description

개량된 동력분무기의 자동감압변 { The automatic decompression device of a improved power sprayer }Automatic decompression device of a improved power sprayer

본 고안은 개량된 동력분무기의 자동감압변에 관한 것이며 동력분무기에서 약액을 설정압력에 이르기까지 압축시켜 이를 약액송출구로 원활하게 공급하고, 약액송출구의 약액송출이 중단되면 약액송출구를 경유한 약액호스의 약액이 여수구로 회수되도록 하고 동력분무기는 공회전되도록 하는 자동감압변에서 송출구측 밸브와 여수구측 밸브구조를 간단히하여 약액의 공급과 차단을 원활히하는 자동감압변에 관한 것이다.The present invention relates to the automatic decompression change of an improved power sprayer, which compresses the chemical liquid up to the set pressure in the power sprayer and supplies it smoothly to the chemical liquid outlet, and the chemical liquid passed through the chemical liquid outlet when the chemical liquid outlet is stopped. It relates to an automatic pressure reducing valve for simplifying the supply and blocking of chemical liquids by simplifying the outlet valve and the free valve valve structure in the automatic pressure reducing valve to allow the chemical liquid of the hose to be recovered to the sewer.

일반적으로 동력분무기는 약액을 10~50kg/㎤의 고압으로 악축시키고 이를 과수나 농작물의 병충해 방제에 주로 사용하게 된다.Generally, the power sprayer compresses the chemical liquid at a high pressure of 10 to 50 kg / cm 3 and uses it mainly to control pests of fruit trees or crops.

또 세차장에서 용수를 고압으로 압축시켜 자동차등의 세차에도 이용하게 된다.In the car wash, the water is compressed to high pressure and used for washing cars.

이와 같은 동력분무기는 약액(용수)을 설정압력으로 압축하기 위하여 동력분무기의 약액압축실의 헤드에 압력조절밸브를 설치하게 되고 설정압력이상이 되면 압축실의 약액은 여수구를 통하여 배출되도록 하여 설정압력을 유지하게 된다.In order to compress the chemical liquid (water) to the set pressure, the power sprayer is provided with a pressure control valve in the head of the chemical liquid compression chamber of the power sprayer. When the pressure exceeds the set pressure, the chemical liquid in the compression chamber is discharged through the sewer. Will be maintained.

이 때 동력분무기에서 압축된 약액이나 용수는 송출구에서 약액호스를 거쳐 분사대를 통하여 사용하게 되고, 설정압력이 유지되도록 동력분무기의 작동이 계속되며 압축된 약액이 분사대에서 사용이 중단되면 고압분무기는 계속 작동되어 약액압축력이 상승되고 상승된 약액은 압력조절밸브의 동작으로 여수구로 회수되는 과정을 거치게 되면서 동력분무기는 부하를 받게 되어 사용수명이 저하되고 또 동력분무기의 가동에 동력의 손실이 발생되는 결점이 있다.At this time, the chemical liquid or water compressed by the power sprayer is used through the spray rod through the chemical liquid hose at the outlet, and the operation of the power sprayer is continued to maintain the set pressure. As the sprayer continues to operate, the chemical liquid compressive force is increased, and the chemical liquid is recovered to Yeosu through the operation of the pressure regulating valve. As a result, the power sprayer receives a load and the service life decreases. There is a drawback that arises.

이를 해소하는 수단으로 실용신안등록제295334호 동력분무기의 자동안전밸브(일명 자동감압변)는 동력분무기의 압축실헤드에 결합되는 안전밸브로서 약액송출구에는 바이패스밸브를, 수직되는 상부에는 세라믹밸브를, 세라믹밸브의 상부측에는 여수구를 각 구비하여 구성된다.As a means to solve this problem, Utility Model Registration No. 295334, the automatic safety valve (also called auto decompression valve) of the power sprayer, is a safety valve that is coupled to the compression chamber head of the power sprayer. The upper side of the ceramic valve is provided with a sewer port.

동 수단은 동력분무기에서 약액을 압축하게 되면 압축된 약액은 바이패스밸브를 통과하여 약액호스를 거쳐 분사대에서 분사가 이루어지고, 분사대에서 약액분사가 중단되면 약액호스내의 압력이 상승하게 되어 바이패스밸브가 약액송출구를 차단하게 되고 약액호스의 약액은 바이패스통로를 거쳐 세라믹밸브를 하강시켜 압축실의 약액이 여수구로 연결되도록 하여 압축실의 약액이 여수구를 통하여 송출되면서 압력이 하강되고 고압분무기는 펌프기능으로 전환되어 동력분무기의 부하를 해소하고 동력의 소모를 줄일 수있게 되는 것이다.When the means compresses the chemical liquid in the power sprayer, the compressed chemical liquid passes through the bypass valve and is injected through the chemical liquid hose, and when the chemical liquid injection is stopped in the spraying rod, the pressure in the chemical liquid hose is increased. The pass valve blocks the chemical liquid outlet and the chemical liquid in the chemical hose is lowered through the bypass passage to lower the ceramic valve so that the chemical liquid in the compression chamber is connected to Yeosu. The nebulizer can be switched to the pump function to offload the power sprayer and reduce power consumption.

이와 같은 동 수단은 송출구에 구비되는 바이패스밸브와 여과망의 구조와 여수구를 개폐하는 세라믹 밸브의 구조가 복잡하고 이물질이 끼이게 되면 기능을 상실하게 되는 결점이 발생되고 있다.Such a means has a drawback in that the structure of the bypass valve and the filtering network provided in the outlet and the ceramic valve for opening and closing the drainage port is complicated and the foreign matter gets stuck and the function is lost.

이에 본 고안은 이와 같은 종래의 제반결점을 해소하고 자동감압변에서 송출구를 개폐하는 송출구밸브와 여수구를 개폐하는 여수구밸브구조를 간단히 하여 양산함에 일차적 목적이 있고 약액의 공급과 차단을 원활히 하고 장구히 사용하는 부수적인 목적을 제공함에 목적이 있다.In this regard, the present invention has the primary purpose of mass production by eliminating the above-mentioned general defects and simplifying the outlet valve structure for opening and closing the outlet port in the auto decompression valve and the outlet valve structure for opening and closing the outlet port. Its purpose is to provide ancillary purposes for long term use.

도면 중 미설명부호 50은 동력분무기헤드체결구, 51은 실린더, 60은 동력분무기의 송출구헤드를 표시한 것이다.In the drawings, reference numeral 50 denotes a power atomizer head fastener, 51 a cylinder, and 60 denotes an outlet head of the power atomizer.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안의 동력분무기용 자동감압변을 통상 동력분무기의 송출구헤드(60)에 취부시켜 설치하고 자동감압변의 압력조절손잡이(39)를 좌측 또는 우측으로 돌려서스프링(38)의 텐션을 조절하여 설정압력을 조절하고 동력분무기를 작동시키게 되면 동력분무기에서 약액이 압축되어 자동감압변본체(1)의 약액분출통로(1a)를 통하여 상승하게 되고 동 약액은 송출구(1b)의 밸브실(1f)에 위치하는 송출구밸브(3)의 스프링(23) 압력보다 커지게 되면 볼(20)을 밀어 고압의 약액은 밸브실(1f)로 유치되고 송출구밸브(3)의 통공(21)으로 유입되어 지지관(22)을 거쳐 송출구밸브(3)를 통과하고 접속관(5)을 거쳐 송출이 이루어지게 되며 송출구(1b)의 접속관(5)에는 약액호스가 연결되고 약액호스 끝 지점에 연결된 분사대에서 분사가 이루어지게 된다.The auto decompression valve for the power sprayer of the present invention is usually mounted on the outlet head 60 of the power sprayer, and the tension adjustment knob 39 of the auto decompression valve is turned left or right to adjust the tension of the spring 38. When the pressure is adjusted and the power sprayer is operated, the chemical spray is compressed in the power sprayer to rise through the chemical spray passage 1a of the automatic pressure reducing body 1, and the chemical sprays the valve chamber 1f of the outlet 1b. When the pressure is greater than the spring 23 pressure of the outlet valve 3 located at the pressure, the ball 20 is pushed to attract the high pressure chemical liquid into the valve chamber 1f and flow into the through-hole 21 of the outlet valve 3. Through the support pipe 22 through the outlet valve (3) and the discharge is made through the connection pipe (5), the chemical liquid hose is connected to the connection pipe (5) of the outlet (1b) and the chemical liquid hose end point The injection is made at the jetting station connected to the.

이 때 약액분출로(1a)의 밸브실(1e)에 위치하는 여수구밸브(2)는 스프링(11)의 탄력으로 볼(10)이 여수구통로를 차단한 상태가 되는 것이다.At this time, the drain valve 2 located in the valve chamber 1e of the chemical liquid ejection passage 1a is in a state in which the ball 10 blocks the drain channel through elasticity of the spring 11.

이와 같이 동력분무기에서 고압으로 조성된 약액이 자동감압변본체(1)의 송출구(1b)로 송출되어 약액호스를 거쳐 분사대에서 분사가 이루어지는 과정에서 과수나 농작물을 방제하거나 또는 자동차등의 세차에 사용되어지게 되고 분사대에서 약액의 분사를 완료하고 약액의 송출을 방지하거나 이동하기 위하여 차단하게 되면 송출구(1b)에는 약액의 송출이 중단되면서 압력이 상승하게 되고 상승된 고압의 약액은 약액이송로(40)를 통하여 여수구밸브작동실(1d)로 이송되어 설정압력보다 커지게 되면 여수구밸브작동실(1d)의 압력으로 압력조절구(4)의 피스톤(31)을 하강하게 되고 동 피스톤(31) 하방의 볼하강핀(32)이 여수구밸브작동실(1d)에 위치하는 볼(10)을 하강시켜 여수구통로를 열어주게 되어 자동감압변본체(1)의 저부에 위치하는 약액분출통로(1a)의 약액은 여수구통로를 거쳐 여수구(1c)로 이송이 이루어지면서 압력이 순간적으로 상압상태로 감압되어지고 동력분무기는 작동되더라도 펌프의 기능으로 전환되어 부하가 걸리지 않게 되고 이로 인하여 동력분무기는 부하가 급격히 감소되고 동력의 소모도 감소된다.In this way, the chemical liquid formed at high pressure in the power sprayer is discharged to the discharge port 1b of the automatic pressure reducing body 1, and the fruit liquid hose is sprayed through the chemical liquid hose in the process of spraying the fruit or crop or washing the car. When the injection of the chemical liquid is completed and the injection block is blocked in order to prevent or move the chemical liquid, the discharge of the chemical liquid is stopped at the discharge port 1b and the pressure is increased. When it is transferred to the sewage valve operation chamber 1d through the transfer path 40 and becomes larger than the set pressure, the piston 31 of the pressure regulator 4 is lowered by the pressure of the sewage valve operation chamber 1d and the same piston (31) The lower ball lowering pin (32) lowers the ball (10) located in the drain valve operation chamber (1d) to open the drainage passage, and the chemical liquid passage passage located at the bottom of the automatic pressure reducing body (1). (1a) As the liquid is transferred to Yeosu-gu (1c) via Yeosu-gu passage, the pressure is reduced to atmospheric pressure momentarily and even if the power sprayer is operated, it is converted to the function of the pump so that the load is not applied. And power consumption is reduced.

또, 본 고안에서 약액이 분사대에서 다시 분사가 이루어지면 자동감압변본체(1)의 송출구(1b)를 통과한 약액의 압력이 떨어지게 되면서 여수구밸브작동실(1d)의 압력이 떨어지고 반대로 약액분출통로(1a)의 압력은 상승되면서 압력조절구(4)의 피스톤(31)을 상승시켜 약액분출통로(1a)의 밸브실(1e)에 위치하는 여수구밸브(2)의 스프링(11)이 상승되는 볼(10)을 지지하면서 여수구 통로를 차단하게 되고 약액은 송출구(1b)의 송출구밸브(3)를 열어서 약액을 송출구로 이송하게 되고 송출구(1b)에 연결된 약액호스를 거쳐 분사대에서 약액의 원활한 분사가 이루어지게 되는 동작이 자동으로 이루어지게 된다.In addition, in the present invention, when the chemical liquid is injected again from the spraying rod, the pressure of the chemical liquid passing through the outlet 1b of the automatic pressure reducing body 1 drops, while the pressure of the sewage valve operation chamber 1d drops and the chemical liquid is reversed. As the pressure of the jet passage 1a is raised, the piston 31 of the pressure regulating opening 4 is raised to raise the spring 11 of the sewage valve 2 located in the valve chamber 1e of the chemical liquid jet passage 1a. While supporting the rising ball 10, it blocks the channel of the yeosu-gu and the chemical liquid is opened through the outlet valve 3 of the outlet port 1b to transfer the chemical solution to the outlet port, and then sprayed through the chemical solution hose connected to the outlet port 1b. The operation of the smooth injection of the chemical in the stage is made automatically.
