한편 후자의 자연낙하 방식에 의한 계량장치에서는 상기 뉴우마틱 방식의 것에 비해서 단순한 구성으로 되는 이점이 있으나, 그러기 위해서는 액체보급탱크를 계량관 본체 보다도 상부에 위치시켜, 계량관에는 오버후로오 장치를 필요로 한다.On the other hand, in the latter natural dropping method, there is an advantage in that it has a simple configuration as compared to the pneumatic method, but in order to do this, the liquid supply tank is located above the main body of the metering tube, and the overflowing device is placed in the metering tube. in need.

더욱이 계량관의 출구는 더욱 밑으로 위치시키지 않으면 안되는 제약조건이 있다.Moreover, there is a constraint that the outlet of the metering tube must be placed further down.

본 고안은 상기와 같은 종래의 계량장치의 문제점을 해소할 수가 있는 뉴우마틱 방식에 의한 액체계량장치를 제공함을 목적으로 하고 있다.The object of the present invention is to provide a liquid metering device by a pneumatic method that can solve the problems of the conventional metering device as described above.

다음, 본 고안의 일실시예를 도면에 따라 설명한다.Next, an embodiment of the present invention will be described with reference to the drawings.

제1도는 본 고안에 의한 액체계량장치를 표시하고 있고, (1)은 액체보급탱크이고, 이 탱크내에 일정레벨의 액체(예를들면 청정수)를 자동적으로 공급하는 자동급액 제어장치(2)를 설치하고 있고, 이 장치(2)에 의해 탱크(1)내의 액체레벨은 항상 일정레벨 h에 조정된다. (3)은 액체보급탱크(1)와 거의 동일평면상에 설치된 밀폐형의 액체계량관(내경 40mm, 높이 180mm)이고, 액체용 2방향전자변(4)을 구비한 연통용 튜우브(5)를 끼워서 탱크(1)와 연통되어 있고, 탱크(1)내의 액체는 이 연통용 튜우브(5)에서 2방향전자변(4)을 거쳐 계량관(3)내에 도입된다.1 shows a liquid metering device according to the present invention, (1) is a liquid supply tank, and an automatic liquid supply control device (2) for automatically supplying a certain level of liquid (eg, clean water) into the tank. The liquid level in the tank 1 is always adjusted to a constant level h by this apparatus 2. (3) is an airtight liquid metering tube (inner diameter of 40 mm, height of 180 mm) installed on substantially the same plane as the liquid supply tank (1), and a communication tube (5) having a two-way electromagnetic valve (4) for liquids is provided. In communication with the tank 1, the liquid in the tank 1 is introduced into the metering tube 3 through the two-way electromagnetic valve 4 in this communication tube 5.

이 계량관(3)내에는 내경 약 4mmø의 레벨조정겸 공기압송튜우브(6) 및 내경 약 2mmø의 액체이송계량튜우브(7)가 삽입되어 있고, 튜우브(6)의 하단은 탱크(1)의 액체레벨 h보다 하위의 레벨 ho에 위치되고, 튜우브(7)의 하단은 그것보다 다시 하위의 계량관(3)저부 가까이 까지 도달되어 있다.In this metering tube 3, a level adjustment and air pressure tubing 6 having an inner diameter of about 4 mm and a liquid transfer metering tube 7 having an inner diameter of about 2 mm are inserted, and the lower end of the tubing 6 has a tank (1). Is positioned at a level ho lower than the liquid level h of), and the lower end of the tube 7 is reached again near the bottom of the metering tube 3 lower than that.

또한, 튜우브(7)의 타단은 대기개방(大氣開放)되어 있다. (8)은 계량관(3)의 상단에 장착된 계량관 시일캡이고, 계량관(3)을 시일함과 동시에 이 계량관(3)내에 삽입된 튜우브(6),(7)를 지지고정하고 있다.In addition, the other end of the tub 7 is open to the atmosphere. (8) is a metering tube seal cap mounted on the upper end of the metering tube (3), and seals the metering tube (3) and at the same time supports the tubing (6), (7) inserted into the metering tube (3) It is fixed.

(9)는 액면가압용의 에어펌프이고, 통상 0.1∼0.5kg/cm2.G의 압력 공기를, 튜우브(10), 공기용 3방향 전자변(11)을 거쳐 레벨조정겸 공기압송튜우브(6)에서 계량관(3)내에 송입(送入)한다.(9) is an air pump for liquid level pressurization, and a pressure adjusting and pneumatic conveying tube (6) through a tub (10) and a three-way solenoid (11) for air through a pressure air of 0.1 to 0.5 kg / cm 2 .G. ) Is fed into the metering pipe (3).

계량관(3)은 제2도에 확대하여 표시된 바와 같이 벌려져 있고 이 벌려진 단부에 상기 시일캡(8)이 감착(嵌着)되어 있고, 또 하단부에 액체도입용노즐(3a)이 설치되어 있어서 노즐(3a)에 연통용튜우브(5)의 단부가 착설되어 있다.The metering tube 3 is open as shown in enlarged view in FIG. 2, and the seal cap 8 is attached to the open end, and a liquid introduction nozzle 3a is provided at the lower end thereof. The end part of the communication tube 5 is installed in the nozzle 3a.

제3도는 자동급액제어장치(2)의 일예로서 종래 형식의 보오드탭을 표시한 것으로, 탱크(1)에 고정된 몸체(12)에서 밑으로 뻗은 브래키트(13)에, 부체(14)를 착설한 작동바아(15)를 착설하고, 이 작동바아(15)의 일단을 일련의 링크(16), 레바(17), 링크(18)를 끼워서 몸체(12)측에 연결함과 동시에, 레바(17)에 변봉(弁棒)(19)의 하단을 착설하고 있고, 작동바아(15)가 도면중의 실선의 위치에 있을때(탱크(1)내의 액체레벨 h일때)는 변봉(19)에 연결된 도면밖의 변이 닫혀져 급액구(給額口)(20)에서의 액체의 공급은 정지되어 있으나, 탱크(1)내의 액체레벨 h보다 처져서 작동바아(15)가 도면중의 가상선으로 표시되는 위치에 회동되기 시작하면 이에 따라서 링크(16), 레바(17), 링크(18)가 요동되고 이에 의해 변봉(19)이 상승되어 도시되지 않는 변이 열리고, 그결과 급액구(20)에서 액체의 공급이 개시된다.3 shows a board tab of a conventional type as an example of the automatic liquid supply control device 2. The floating body 14 is attached to a bracket 13 extending downward from the body 12 fixed to the tank 1. The installed operating bar 15 is installed, and one end of the operating bar 15 is connected to the body 12 by inserting a series of links 16, levers 17 and links 18, and at the same time. The lower end of the rim 19 is installed at 17, and when the operation bar 15 is at the position of the solid line in the drawing (when the liquid level h in the tank 1), the rim 19 The outside of the connected figure is closed and the supply of the liquid from the liquid supply port 20 is stopped, but the position where the operating bar 15 is indicated by the virtual line in the figure is lower than the liquid level h in the tank 1. When it starts to rotate, the link 16, the lever 17, and the link 18 are swung accordingly, and the edge 19 is raised so that the side not shown is opened, resulting in the supply port 20. The supply of the liquid is started.

이리하여 탱크(1)에 공급되는 액체의 레벨이 h에 도달하면 변이 닫혀져 급액은 정지된다.Thus, when the level of the liquid supplied to the tank 1 reaches h, the side is closed and the liquid supply stops.

또한 공급용의 액체는 탱크(1) 외부에서 액체도입관(21)을 통하여 보오트탭에 보내져 있다.In addition, the liquid for supply is sent to the boat tap via the liquid introduction pipe 21 from the outside of the tank 1.

다음에 상기와 같이 구성으로되는 계량장치의 동작을 제4도의 동작 시퀀스에 따라 설명한다.Next, the operation of the weighing device having the above configuration will be described according to the operation sequence of FIG.

지금 2방향전자변(4)이 열리고, 또한 전자변(11)이 동작하지 않는 상태[튜우브(6)가 COMMON측에서 N-O(상시열림)측의 입구에서 대기개방되어 있는 상태]로서, 액체보급탱크(1)내에 액체가 자동급액 제어장치(2)를 거쳐 일정레벨 h까지 채워져 있다고 하면, 계량관(3)내에는 제2도에 표시한 ho의 레벨까지 액체가 유입되고 튜우브(6),(7)내에는 상기 h의 레벨까지 액체가 유입되어 있다. 이것은 계량관(3)이 대기개방으로되는 것은 이송계량튜우브(7)의 일단과, 레벨조정겸 공기압송튜우브(6)에 연설한 공기용 3방향전자변(11)의 COMMON과 N-O계에 있어서만이므로, 계량관(3)내에 있어서, 액체가 ho 레벨에 도달하면, 계량관(3)내의 잔여공간은 밀폐되는 것으로 되기 때문이다.The liquid supply tank is in the state where the two-way electromagnetic valve 4 is open and the electromagnetic valve 11 is not operated (a state in which the tub 6 is atmospherically opened at the entrance of the NO (normally open) side at the common side). If the liquid in (1) is filled to a certain level h via the automatic liquid supply control device 2, the liquid flows into the metering pipe 3 to the level of ho shown in FIG. In (7), liquid flows to the level of said h. This means that the metering pipe 3 is opened to the atmosphere in one end of the feed metering tube 7 and in the common and NO system of the three-way electromagnetic valve 11 for air, which is addressed to the level adjusting and air pressure feeding tube 6. This is because only the remaining space in the metering tube 3 is sealed when the liquid reaches the ho level in the metering tube 3.

따라서, 상기 레벨조정겸 공기압송 튜우브(6)를 승강하는(ho 레벨을 변경함)것에 의해서 필요로 하는 액체의 계량을 조정하는 것이 가능하게 된다.Therefore, it is possible to adjust the metering of the required liquid by raising and lowering (changing the ho level) the level adjusting and air-pressing tubing 6.

또 이송계량튜우브(7)를 승강하는 것에 의해서도 동일한 효과가 있고, 탱크(1)의 액면레벨과 계량관(3)의 내경을 변경하는 것에 의해서 매우 광범위한 액체의 계량이 될수 있다.The same effect can be obtained by elevating the feed metering tube 7, and a very wide range of liquid can be measured by changing the liquid level of the tank 1 and the inner diameter of the metering tube 3.

이와 같이하여 계량관(3)내에서 일정레벨로 조정된 액체는 에어펌프를 작동하고, 액체용 2방향전자변(4)을 닫고 공기용 3방향전자변(11)의 COMMON측과 N-C(상시닫힘)측을 연결하면, 에어펌프(9)의 공기압력이 계량관(3)내의 수면에 가해지기 때문에 유일한 출구인 이송계량튜우브(7)를 거쳐 배출, 계량된다.In this way, the liquid adjusted to a constant level in the metering pipe 3 operates the air pump, closes the liquid two-way electromagnetic valve 4, and closes the common side and the NC (normally closed) of the air three-way electromagnetic valve 11. When the side is connected, the air pressure of the air pump 9 is applied to the water surface in the metering pipe 3, and is discharged and metered through the feed metering tube 7 which is the only outlet.

또한, 배출, 계량되는 액체의 양은,In addition, the amount of liquid discharged and metered is

γ1:튜우브(6)의 반경γ 1 : radius of the tube 6

본 고안에 의한 액체계량장치는, 종래의 뉴우마틱 방식에 의한 장치에 대하여 부품수의 점, 계로(系路)의 간소화의 면에서 매우 효과가 있고, 또 정도적(精度的)으로 보아도 오차는±3∼5% 정도이고 그다지 문제되지 않는다.The liquid metering device according to the present invention is very effective in terms of the number of parts and the simplification of the system path with respect to the conventional device based on the pneumatic method. Is ± 3 to 5% and is not a problem.

한편, 자연낙하 방식에 있어서와 같은 설치조건의 제약을 받지 않고, 오버후로시키는 장치도 필요없고 더욱이 계량관자체도 가장 간단한 구조로되는 이점이 있다.On the other hand, without being constrained by the installation conditions as in the natural dropping method, there is no need for an over-flowing device, and furthermore, the metering pipe itself has the advantage of being the simplest structure.

다시, 종래의 계량관이 그 필요용량에 대하여 개별로 계량관을 만드는 여부의 수단으로 용적을 규정하는 수단을 취하고 있었으나, 본 고안에서는 예를들면 20ml∼150ml까지 동일한 계량관에 의해 액면 레벨의 조정만으로 목적을 달성할수가 있다.Again, although the conventional metering tube has a means of defining the volume as a means of making a metering tube individually for the required capacity, in the present invention, for example, the liquid level is adjusted by the same metering tube from 20ml to 150ml. You can achieve your purpose alone.
