Description
본 고안은 동력 분무기의 압력 조절장치에 관한 것으로 보다 구체적인 것은 분무 작업 도중에 작업자가 분무작업을 일시 중지할 경우 배출부로 작용되던 압력이 역류하여 압력 조정장치의 해소부를 통해 외부로 해소되도록 압력 조절장치를 구성하므로서 배출부에 연결된 분무 호스가 파손되는 것을 막고 분무작업을 속행할때 편리하도록 한 것이다.The present invention relates to a pressure regulator of the power sprayer. More specifically, the pressure regulator is used to relieve the pressure outside the pressure regulator in order to reverse the pressure acting as the discharge part when the worker pauses the spraying operation during the spraying operation. It is designed to prevent damage to the spray hose connected to the discharge portion and convenient when continuing the spray operation.
종래에도 동력 분무기의 압력을 조절하기 위한 장치로서 실용신안등록 제278634호가 공지되어 있다.Conventionally, Utility Model Registration No. 278634 is known as a device for adjusting the pressure of a power sprayer.
그러나 종래의 압력 조절장치는 분무기의 송출부와 압력 제어 밸브몸체가 연결되는 제1밸브실에 역지 밸브가 장치되고 제1밸브실에서 외부로 토출되는 제2밸브실에 체크밸브가 장치되어 송출되는 압력의 역류를 방지하고 있다.However, the conventional pressure regulator is provided with a check valve is provided in the first valve chamber is connected to the discharge portion of the sprayer and the pressure control valve body and the check valve is provided in the second valve chamber discharged from the first valve chamber to the outside It prevents the back flow of pressure.
그러나 제2밸브실에 장치된 체크밸브의 개폐부가 평판으로 되어 있어서 이물질이 개입되면 체크밸브의 작동이 원활하지 못해 역류가 일어나고 고장의 원인이 되는 불편이 있고, 압력해소를 위해 고무막을 사용하고 있으나 고무막이 반원형으로 구성되어 있어서 압력의 변화에 민감하게 대응하지 못하는 불편이 있었으며 압력해소실에 장치되는 패킹이 제이형 패킹으로 되어 있어서 동작의 신뢰성이 유지되지 못하는 등 불편이 있었다.However, since the opening and closing portion of the check valve installed in the second valve chamber is flat, if foreign matters are involved, the check valve may not work smoothly, causing backflow and causing trouble, and using a rubber membrane to relieve pressure. Since the rubber membrane is semi-circular, it is inconvenient to respond to pressure changes sensitively, and the packing installed in the pressure releasing chamber is made of J-type packing.
본 고안은 위와같은 종래의 불편을 개선하여 보다 정확한 압력조정이 이루어질수 있게 조절장치를 개발한 것인데 이를 보다 상세히 설명하면 다음과 같다.The present invention is to improve the conventional inconveniences as described above to develop a control device to make a more accurate pressure adjustment described in more detail as follows.

본 고안은 분무기의 송출부(1)와 연결되는 조절장치 몸체부(2)에 송출액이 유입되는 제1밸브실(3)과, 제1밸브실(3)과 수평연결공(3a)으로 이어지는 제2밸브실(4)과, 제1밸브실(3)과 수직으로 연통하는 비상 배출실(7)의 연통공(702)과 연결되는 압력해소실(5)과, 압력해소실(5)과 수평연결공(5a)으로 연결되고 제2밸브실(4)과 상하연결공(4a)으로 이어지는 가압밸브실(6)이 구분되어 형성되는 압력조절장치로서 제1밸브실(3) 내에는 밸브안내관(301)이 내장되어 밸브안내관(301) 상단 외주에 환상요입홈(302)을 형성하고 그 일측에 통공부(302a)를 형성하고 밸브안내관(301) 하단에 고정관(303)을 나사조립하여 고정시킨후 밸브안내관 내부에 역지밸브(304)가 코일스프링(305)에 장진되도록 장치되어 그 상단이 비상배출실(7)의 하측 밸브시이트(701)에 밀착되게하고 비상배출실(7)의 상부에 설치된 압력해소실(5)에 작동봉(8)를 삽입하여 상단에 손잡이(801)가 부착되고 하단이 역지밸브 상단에 연결되게한후 압력해소실(5) 하측에 위치하는 작동봉 외주에 피스톤(802)을 장치하여 ㅇ링(803)으로 기밀시키고 가압밸브(6)에는 신축주름(602)이 구비된 고무막(601)을 횡삽하여 그 외측을 마개(603)로 나사끼움하여 연결공(4a)과 연통하는 내측에 연통홈(604)를 형성하고 제2밸브실(4)에는 원추형 접촉부(401)를 만들어 스프링(402)에 탄압되는 팽이형 역지밸브(403)를 개입하고 외측에 안내관(404)을 끼워서 그 연통공(404a)을 통해 고정관(405)의 중심배출공(406)으로 약제가 배출되게한 구조이다.The present invention is the first valve chamber (3), the first valve chamber (3) and the horizontal connection hole (3a) that the liquid is introduced into the regulator body portion (2) connected to the delivery unit (1) of the sprayer The second valve chamber 4, the pressure relief chamber 5 connected to the communication hole 702 of the emergency discharge chamber 7, which is in vertical communication with the first valve chamber 3, and the pressure relief chamber 5 ) Is a pressure regulating device which is connected to the horizontal connection hole (5a) and is formed by separating the pressure valve chamber (6) leading to the second valve chamber (4) and the vertical connection hole (4a) in the first valve chamber (3). The valve guide tube 301 has a built-in annular groove 302 formed on the outer periphery of the valve guide tube 301 and the through-hole 302a is formed on one side and the fixed pipe 303 at the bottom of the valve guide tube 301 ) Is assembled so that the check valve 304 is loaded in the coil spring 305 inside the valve guide tube so that its upper end is in close contact with the lower valve seat 701 of the emergency discharge chamber 7 Discharge chamber (7 Insert the operating rod (8) into the pressure relief chamber (5) installed on the upper part of the) so that the handle (801) is attached to the upper end and the lower end is connected to the upper check valve, the operation located below the pressure relief chamber (5) Piston 802 is installed on the outer periphery of the rod to seal it with a ring 803, and the pressure valve 6 is horizontally inserted into the rubber membrane 601 provided with the elastic wrinkles 602, and the outside thereof is screwed with a stopper 603. A communication groove 604 is formed on the inner side in communication with the connection hole 4a, and a conical contact portion 401 is formed in the second valve chamber 4 to intervene the top check valve 403 pressed against the spring 402. The guide tube 404 is inserted to the outside, the drug is discharged to the center discharge hole 406 of the fixed tube 405 through the communication hole (404a).
이와같이된 본 고안은 분무기에서 송출되는 약제가 송출부(1)에서 조절장치 몸체부(2)의 제1밸브실(3)에 유입되면 역지변(304)이 비상배출실(7)을 막고 있기 때문에 밸브안내관(301)의 통공부(302a)를 통해 환상요입홈(302)을 거쳐 제2밸브실(4)의 팽이형 역지밸브(403)을 밀고 배출안내관(404)의 연통공(404a)을 통해 고정관(405) 중심배출관(406)을 들어가서 분무호스(407)로 배출되고 사용중에 분무작업을 일단 중지하게 되어 분무호스(407)내에 압력이 차게 되면 그 압력이 팽이형 역지밸브(403)를 내측으로 밀어 제2밸브실(4)의 연결공(3a)을 달기 때문에 제2밸브실에 작용하는 압력은 가압밸브실(6)로 작용하여 고무막(601)을 밀게 되는데 고무막(402)은 그 주벽이 주름(602)으로 되어 있어서 주름이 널어나면서 고무막(602)이 압력해소실(5) 쪽으로 이동하여 연결공(5a)을 통해 압력해소실에 압력을 가하면 압력해소실(5)에 작용하는 압력을 작동봉(8)의 피스톤(802)은 밀어 작동봉(8)을 하강시키므로 비상배출실(7)의 하단 역지밸브(304)를 아래로 밀어 주기 때문에 밸브시트(701) 사이에 간격이 발생하여 제1밸브실에 약액이 비상배출실(7)을 통해 외부로 배출되어 제1밸브시의 압력을 해소시키게 되는 것이다.The present invention, as described above, when the medicine discharged from the sprayer flows from the discharge unit 1 to the first valve chamber 3 of the control unit body 2, the check valve 304 is blocking the emergency discharge chamber (7) Therefore, through the through hole 302a of the valve guide tube 301, the push-type check valve 403 of the second valve chamber 4 is pushed through the annular recess groove 302, and the communication hole of the discharge guide tube 404 ( 404a enters the center discharge pipe 406 through the fixed tube 405 and is discharged to the spray hose 407 and once the spraying operation is stopped during use, the pressure in the spray hose 407 is filled with the pressure check valve ( Since the 403 is pushed inward to connect the connection hole 3a of the second valve chamber 4, the pressure acting on the second valve chamber acts as the pressure valve chamber 6 to push the rubber membrane 601. The 402 has a circumferential wall formed of a pleat 602 so that the pleats are squeezed and the rubber membrane 602 moves toward the pressure releasing chamber 5 and through the connecting hole 5a. When pressure is applied to the pressure releasing chamber, the piston 802 of the operating rod 8 pushes the pressure acting on the pressure releasing chamber 5 and lowers the operating rod 8 so that the lower check valve 304 of the emergency discharge chamber 7 is provided. Since the gap is generated between the valve seat 701, the chemical liquid is discharged to the outside through the emergency discharge chamber (7) to relieve the pressure at the first valve.
이로인하여 제1밸브실과 제2밸브실의 연결공(3a)은 팽이형 역지밸브(403)에 의하여 폐쇄되므로 분무호스내에 압력이 해소되어 호스가 보호되고 분무를 다시 시작하게 되면 전과 같은 작용이 반복되어 제1밸스실 상측의 비상배출실은 역지밸브에 의하여 폐쇄되고 제2밸브(4)의 배출공이 열성의 분무작업을 순탄하게 속행하게 된다.As a result, the connection hole 3a of the first valve chamber and the second valve chamber is closed by the top check valve 403, so the pressure in the spray hose is released, the hose is protected, and the spraying is restarted. As a result, the emergency discharge chamber above the first balance chamber is closed by the check valve, and the discharge hole of the second valve 4 smoothly continues the thermal spraying operation.
따라서 본원고안은 동력 분무기의 압력을 편리하게 고정할수 있으며 제1밸브실과 제2밸브실의 역지 밸브가 안내관에 안내되도록 장치되어 있어서 작동부가 고장날 염려가 없게되는 이점이 있어 작동 신뢰성을 높힐수 있고 고무막의 작동이 정확하여 가압밸브실(6)에서 압력해소실로 작동하는 압력절단이 정확하게 되며 압력해소실에 장치된 작동봉(8)은 그 가압부가 ㅇ링이 개입된 피스톤으로 구성되어 고장의 염려가 없으면서 작동이 정확하고 수명이 오래가는 이점을 얻게 되는 것이다.Therefore, the present application can conveniently fix the pressure of the power sprayer, and the check valves of the first valve chamber and the second valve chamber are guided to the guide tube, so that there is no fear that the operating part will break down, thereby increasing the operation reliability. The operation of the rubber membrane is accurate, so the pressure cut from the pressure valve chamber 6 to the pressure relief chamber is accurate, and the operating rod 8 installed in the pressure relief chamber is composed of a piston in which the pressure part intervenes. The benefits are accurate and long life.
