Description
본 고안은 고압 분무기에서 약액을 흡입 또는 토출용으로 사용되는 밸브에 관한 것으로The present invention relates to a valve used for suction or discharge of a chemical liquid in a high pressure sprayer
더욱 상세하게는 밸브의 오동작을 방지하며 정밀가공으로 누수를 방지하고 소음을 줄이도록 하는 분무기용 밸브에 관한 것이다.More particularly, the present invention relates to a valve for a nebulizer, which prevents malfunction of the valve and prevents leakage by reducing precision and reduces noise.
일반적으로 고압 분무기에는 도 1 과 같이 배출실(22)과 실린더(20)의 사이에 토출밸브(19')를 설치하고, 흡입실(21)과 실린더(20)의 사이에 흡입밸브(19)를 설치하게 된다.In general, the high-pressure sprayer is provided with a discharge valve 19 'between the discharge chamber 22 and the cylinder 20, as shown in Figure 1, the suction valve 19 between the suction chamber 21 and the cylinder 20 Will install
상기 밸브(19, 19')는 밸브몸체(28)에 고정지지된 스프링(9)의 상측으로 밀폐판(25)이 설치되고 이 밀폐판(25)은 밀폐 돌출부(26)에 지지되며 밀폐 돌출부(26)와 밸브몸체(28)의 상측은 고정덮개(28)의 내부에 고정되는 구조를 갖는다.The valves 19, 19 ′ are provided with a sealing plate 25 on the upper side of the spring 9 fixed to the valve body 28, and the sealing plate 25 is supported by the sealing protrusion 26 and the sealing protrusion part. 26 and the upper side of the valve body 28 has a structure that is fixed to the interior of the fixing cover (28).
그러나 고정덮개(28)를 제외한 모든 부품이 금속으로 성형되며, 프레스를 이용하여 성형되는 것이다.However, all parts except the fixed cover 28 is formed of a metal, it is molded using a press.
이와 같은 밸브는 흡입 또는 토출을 위해서 교대로 개폐되면서 약액을 흡입 또는 토출하게 된다.Such a valve is sucked or discharged while being alternately opened and closed for suction or discharge.
이때 밀폐판(25)이 밀폐 토출부(11)와 접촉되면서 폐쇄시키고 밀폐판(25)이 스프링(9)을 압축하면서 이동되면서 밀폐상태를 분리하여 개방시키게 된다.At this time, the sealing plate 25 is closed in contact with the sealed discharge part 11 and the sealing plate 25 is moved while compressing the spring 9 to separate and open the sealed state.
그러나 밀폐판(25)이 밀폐와 개방상태를 연속적으로 수행하면서 금속부품간에 심한 소음이 발생하는 결점이 있다.However, while the sealing plate 25 performs the sealing and opening continuously, there is a drawback that a severe noise occurs between the metal parts.
또한 밸브몸체와 밀폐판이 프레스로 성형된 것이어서 밀폐판이 이동중에 밸브몸체에 걸려 작동을 하지 않는 오동작이 자주 발생하는 결점이 있다.In addition, since the valve body and the sealing plate are formed by a press, there is a drawback in that malfunctions frequently occur when the sealing plate is not caught by the valve body while moving.
그리고 밀폐판과 밀폐 돌출부가 만나는 지점에서 수평상태로 만나게 되면서 밀폐시키게 되므로 밀폐에 대한 안전성이 저하되어 누수현상이 발생하는 결점이 있다.In addition, the sealing plate and the sealing protrusion meet in a horizontal state at the point where the sealing is closed, so the safety of the sealing is lowered, there is a defect that the leakage phenomenon occurs.
또한 고정덮개의 안쪽으로 밀폐 돌출부가 위치하는 밸브는 밀폐 돌출부와 고정덮개의 사이로 강하게 형성되어 있는 수압이 작용되어 그 사이가 벌어져 밀폐성능의 저하를 가져오는 결점이 있다.In addition, the valve in which the sealing protrusion is located inside the fixed cover has a drawback in that water pressure is strongly formed between the sealed protrusion and the fixed cover, and thus, the gap between the sealing protrusion and the fixed cover causes a decrease in sealing performance.
본 고안은 이러한 종래의 결점을 해소시키기 위하여 안출된 것으로 밀폐돌출부와 작동밸브를 정밀가공하며 밀폐되는 부분에서 곡면으로 만나서 완벽한 밀폐작용으로 누수를 차단하는 것이다.The present invention has been devised to solve the above-mentioned drawbacks, and precisely processes the hermetic protrusion and the operation valve, and meets the curved surface at the closed portion to block leakage by a perfect sealing action.
본 고안은 밸브몸체를 사출성형하여 소음발생을 방지하고, 정지턱을 통하여 작동밸브가 일정한 작동거리를 정확하게 작동하여 오동작을 하지 않도록 하는 것이다.The present invention is to prevent the occurrence of noise by injection molding the valve body, the operation valve through the stop jaw to operate a certain operating distance accurately to prevent malfunction.
본 고안은 구멍이 일직선으로 형성되며 중간부분에 안쪽으로 작동밸브의 이동을 단속하도록 돌출된 정지턱이 형성된 밸브몸체와,The present invention is formed with a straight hole and the valve body is formed in the middle portion protruding stop jaw to interlock the movement of the operation valve inward,

본 고안은 엔진이나 고압 분무기(1)의 크랭크실(24)과 연결된 플런저(23)가 실린더(20)의 내부에서 왕복이동됨에 따라서 흡입실(21)과 연결된 흡입밸브(2)와 배출실(22)과 연결된 토출밸브(2')에 관한 것이다.According to the present invention, as the plunger 23 connected to the crank chamber 24 of the engine or the high pressure sprayer 1 reciprocates in the cylinder 20, the suction valve 2 and the discharge chamber connected to the suction chamber 21 are provided. It relates to a discharge valve (2 ') connected to 22).
상기 밸브(2, 2')는 고압 분무기(1)에 한정되지 않고 액체를 흡입 또는 토출하는 엔진에 다양하게 적용할 수 있는 것이다.The valves 2 and 2 'are not limited to the high pressure sprayer 1, but can be variously applied to an engine for sucking or discharging liquid.
상기 밸브(2, 2')는 사출을 통하여 성형되는 밸브몸체(3)가 안쪽으로 구멍(7)이 형성되어 있고 상측에서 외측으로 고정턱(8)이 돌출되며, 하측으로 길게 돌출된 후 일정한 간격으로 관통구멍(4)이 형성되고 중간쯤에 구멍(7)이 일자형으로 형성되어 끝나는 부분에 정지턱(5)을 설치하며, 하단에는 관통공(16)과 외측에 스프링 고정턱(6)이 설치된다.The valves 2 and 2 'have a hole 7 formed in the valve body 3 formed through injection, and the fixing jaw 8 protrudes from the upper side to the outer side. Through holes (4) are formed at intervals and the hole (7) is formed in a straight line at the middle of the stop jaw (5) is installed in the end portion, the through hole (16) and the spring fixing jaw (6) on the outside This is installed.
상기 밸브몸체(3)의 구멍(7)에는 스프링(9)이 삽입되어 하측의 스프링 고정턱(6)에 위치하여 중앙에 설치되도록 한다.The spring (9) is inserted into the hole (7) of the valve body (3) so that it is located in the spring fixing jaw (6) of the lower side to be installed in the center.
상기 스프링(9)의 외측에는 작동밸브(10)가 올려지며, 작동밸브(10)는 중앙이 하측으로 호상이 형성되고 그 외측에는 외측으로 곡면(호상)이 형성되도록 하는 것이다.The operation valve 10 is raised on the outside of the spring (9), the operation valve 10 is to form an arc on the lower side of the center and the outer surface (curved) is formed on the outside.
상기 작동밸브(10)의 상측에는 외측의 곡면과 만나는 곡면(13)이 형성되고 외측으로 고정날개(12)가 설치된 밀폐 돌출부(11)가 설치되어 작동밸브(10)와 만나면 밀폐되도록 하는 것이다.The upper surface of the operation valve 10 is formed with a curved surface 13 which meets the outer curved surface and is provided with a sealing protrusion (11) provided with a fixed wing 12 to the outside to be sealed when it meets the operating valve (10).
상기 밀폐 돌출부(11)와 고정턱(8)은 조립 후에 만나게 되므로 고정덮개(14)의 내부에 형성된 고정홈(15)에 함께 삽입하여 고정시키는 것이다.Since the sealing protrusion 11 and the fixing jaw 8 are met after assembly, the sealing protrusion 11 and the fixing jaw 8 are inserted into and fixed to the fixing groove 15 formed in the fixing cover 14.
이러한 구성으로 이루어진 본 고안은 고압 분무기(1)에 적용되는 경우에는 흡입실(21)과 배출실(22)의 사이에 밸브(2, 2')를 설치하는 것이다.The present invention having such a configuration is to install the valve (2, 2 ') between the suction chamber 21 and the discharge chamber 22, when applied to the high-pressure sprayer (1).
크랭크실(24)의 내부에 설치된 크랭크가 엔진의 동력으로 연속해서 회전되면서 플런저(23)를 왕복이동시킴에 따라서 밸브(2, 2')는 연동적으로 개폐되면서 약액을 압축시켜 공급하는 것이다.As the crank installed inside the crank chamber 24 continuously rotates with the power of the engine to reciprocate the plunger 23, the valves 2 and 2 'are interlocked to open and close to supply the chemical liquid.
플런저(23)가 실린더(20)의 내부에서 좌측으로 이동되면서 발생되는 힘으로 작동밸브(10)를 당기면 밀폐 돌출부(11)와 접촉되고 있다가 좌측으로 이동하면서 분리되어 작동밸브(10)가 밸브 몸체(3)의 정지턱(5)에 이르면서 작동밸브(10)의 이동이 정지된다.When the plunger 23 pulls the actuating valve 10 with the force generated while moving from the inside of the cylinder 20 to the left side, the plunger 23 is in contact with the sealing protrusion 11 and is moved while moving to the left to separate the actuating valve 10 from the valve. The movement of the actuating valve 10 is stopped while reaching the stop jaw 5 of the body 3.
작동밸브(10)가 이동되면서 밀폐 돌출부(11)의 하측이 개방되면서 관통구멍(4)이 개방되므로 흡입실(21)에 있는 약액이 관통구멍(4)을 통하여 실린더(20)의 내부에 흡입한다.As the actuating valve 10 is moved, the through hole 4 is opened while the lower side of the sealing protrusion 11 is opened, so that the chemical liquid in the suction chamber 21 is sucked into the cylinder 20 through the through hole 4. do.
이때 밸브(2')에서는 작동밸브(10)가 밀폐 돌출부(11)의 곡면(13)과 일치되어 있어서 약액의 배출을 중단시키게 된다.At this time, in the valve 2 ', the operation valve 10 coincides with the curved surface 13 of the hermetic protrusion 11 to stop the discharge of the chemical liquid.
약액의 흡입이 완료되면 플런저(23)가 우측으로 이동하면서 흡입력을 해제하면서 스프링(9)의 탄성력으로 작동밸브(10)를 상승시켜 밀폐시키게 되고, 밸브(2')에서는 실린더(20)에 흡입된 약액이 압력으로 작동밸브(10)를 개방시켜 배출실(22)에 공급하는 것이다.When the suction of the chemical liquid is completed, the plunger 23 moves to the right to release the suction force, thereby raising the operation valve 10 with the elastic force of the spring 9 to seal it, and the valve 2 'sucks into the cylinder 20. This chemical liquid is to open the operation valve 10 to the pressure to supply to the discharge chamber (22).
여기서 작동밸브(10)는 외측이 곡면으로 형성되고 밀폐 돌출부(11)의 하측 선단을 작동밸브(10)의 외측과 동일한 곡면(13)을 형성하여 작동밸브(10)와 밀폐 돌출부(11)의 곡면(13)이 만나면 상호 곡면의 만남으로 밀폐시에 누수를 확실하게 방지하는 것이다.Here, the actuating valve 10 has a curved surface 13 on the outside thereof and forms the same curved surface 13 as the outside of the actuating valve 10 at the lower end of the sealing protrusion 11 so that the actuating valve 10 and the sealing protrusion 11 may be formed. When the curved surfaces 13 meet, the leakage of water is reliably prevented at the time of sealing by the meeting of the curved surfaces.
또한 작동밸브(10)의 중앙은 하측으로 곡면이 형성되고 외측은 상측으로 곡면이 형성되므로 곡면이 만나는 부분의 하측에서 스프링(9)이 연결되어 상, 하 동작을 수행하므로 정확한 수평을 유지할 수 있으며, 작동밸브(10)가 하강한 후 정지턱(5)에서 정지된 후 다시 상승하도록 하므로 작동밸브(10)의 행정거리를 단속하여 작동밸브(10)가 구멍(7)의 내부에서 걸려 오동작 되는 것을 방지할 수 있는 것이다.In addition, since the center of the operation valve 10 has a curved surface formed on the lower side and a curved surface formed on the outer side, the spring 9 is connected to the lower side of the portion where the curved surface meets to perform the up and down motion, thereby maintaining the correct level. Since the operation valve 10 is lowered and then stopped at the stop jaw 5 and then rises again, the operation distance of the operation valve 10 is interrupted and the operation valve 10 is caught inside the hole 7 to malfunction. This can be prevented.
또한 오동작이 방지되고, 밸브몸체(3)를 사출성형한 것이므로 금속재질이 아니어서 금속 재질인 작동밸브(10)의 이동으로 인한 마찰음의 발생을 방지하여 소음을 감소시키게 되는 것이다.In addition, since the malfunction is prevented and the valve body 3 is injection molded, the noise is reduced by preventing the occurrence of friction noise due to the movement of the operation valve 10 which is not made of metal and is not made of metal.
또한 작동밸브(10)의 이동에 의한 소음을 방지하므로 당연히 고압 분무기(1)의 떨림현상이 방지되는 것이다.In addition, since the noise caused by the movement of the operation valve 10 is prevented, the shaking phenomenon of the high-pressure sprayer 1 is naturally prevented.
본 고안은 작동밸브의 외측면이 상측으로 곡면 형성되며 밀폐 돌출부의 하측으로 곡면을 형성하여 작동밸브와 곡면이 만나면서 상호 밀폐능력이 향상되어 누수를 방지하는 것이다.The present invention is the outer surface of the operation valve is formed to the upper side and the curved surface formed on the lower side of the sealing protrusion to meet the operating valve and the curved surface to improve the mutual sealing ability to prevent leakage.
본 고안은 밸브몸체의 내부에 정지턱을 형성하여 작동밸브가 일정한 거리만을 왕복이동하도록 이동거리를 단속하여 작동밸브의 오동작을 방지하는 것이다.The present invention is to prevent the malfunction of the operation valve by forming a stop jaw in the valve body to control the movement distance so that the operation valve reciprocates only a certain distance.
본 고안은 밸브몸체를 금속재료로 하지 않고 사출성형하여 작동밸브의 이동으로 인한 소음을 줄이고 떨림현상을 방지하는 것이다.The present invention is to reduce the noise caused by the movement of the operating valve to prevent the shaking phenomenon by injection molding without the valve body made of a metal material.
