본 고안은 수위 조절용 정수위 밸브를 순간적으로 전개 또는 폐쇄시키면서 고수위와 저수위를 제어 가능토록 하여 급펌프의 구동신호를 급수관로 자체에서 취함으로 급수에너지의 절감과 급수 시스템 설치 공사비를 줄일수 있게 한 ON.OFF식 고조수위 제어용 정수위 밸브에 관한 것이다.The present invention allows the high and low water level to be controlled while the water level control valve is opened or closed for a moment, so that the driving signal of the feed pump is taken from the water supply line itself, thereby reducing the water supply energy and the water supply system installation cost. The water level valve for OFF high water level control.

종래 사용되고 있는 부력식 정수위 밸브는 밸브가 열린 상태에서 수조에 물이 공급되고 수조의 수위가 상승함에 따라 정수위 밸브도 차츰 닫히기 때문에 설정 최고 수위가 가까워질수록 급수량도 줄어들고 엄격한 의미에서 최고수위에 도달하는데 무한대의 시간이 걸리고 정수위 밸브는 완전히 폐쇄되지 않아 계속되는 펌프의 작동으로 필요 이상의 전력이 소모되며, 또 수압이 높을시는 수압을 견디지 못하여 파손되어 누수가 되는 등 단점이 많이 있으며, 부구의 부력 자체로만 정수위 밸브를 개폐시키기 위해서는 부구와 밸브를 연결한 레바를 길게 하든지 부구를 키우는 방법이 고려되어야 하나 이에는 저수능력의 저항등 손실이 많았다.The buoyancy water level valve used in the prior art is supplied with water to the tank with the valve open and the water level valve closes gradually as the water level rises, so the water supply decreases as the set maximum water level approaches and reaches the highest level in a strict sense. Infinite time is taken and the water valve is not completely closed, and the pump continues to operate, which consumes more power than necessary. In addition, when the water pressure is high, it can not withstand the water pressure and is damaged and leaks. In order to open and close the water level valve, a method of lengthening or raising the lever connected to the float and the valve should be considered, but there were many losses such as resistance of low water capacity.

본 고안은 이러한 단점을 보완하기 위하여 정수위 밸브 내부의 파이롯트 밸브와 유체의 압력을 이용하여 밸브의 개폐를 피스톤에 의해 수행되도록 한 것으로 이를 첨부 도면에 의거 상세히 설명하면 다음과 같다.The present invention was made to perform the opening and closing of the valve by a piston using a pilot valve and the pressure of the fluid inside the valve to compensate for this disadvantage, which will be described in detail with reference to the accompanying drawings.

측면에 유입구(3)가 있는 밸브몸체(1) 내부의 밸브시트(2)에 상판(5)과 하판(6)으로 나누어져 중공부(7)가 있는 피스톤(4)의 상판외주면 링홈(8)에 피스톤링(9)을 결합하고 도압관(10)이 있는 유압실(11) 입구에는 거름망(12)을 끼워 보호링(13)으로 결합하고 중간차간편(14) 통공(14')위에 고무판(15)을 얹은 후 파이롯트(16)를 통공(14')에 삽입 스프링(17)을 안착시켜 유체배출공(19)을 가진 스프링스눌름판(18)을 나사 결합하며 피스톤(4) 하부에 고무박킹(20)을 삽입 가이드(21)를 나사 결합한다.The upper plate outer peripheral surface ring groove 8 of the piston 4 having the hollow portion 7 is divided into the upper plate 5 and the lower plate 6 in the valve seat 2 inside the valve body 1 having the inlet 3 on the side. The piston ring (9) to the hydraulic chamber (11) with the pressure pipe (10) to the inlet of the sieve (12) to the coupling ring (13) and to the intermediate car piece (14) through the hole (14 ') After mounting the rubber plate 15, the pilot 16 is seated in the through hole 14 ′. The spring 17 is seated, and the spring press plate 18 having the fluid discharge hole 19 is screwed into the bottom of the piston 4. Screw the rubber boxing 20 into the insertion guide 21.

그리고 파이롯트 작동레바(22)의 원형통공(22')에 파이롯트밸브(16)를 삽입하여 하단 일측 원형돌출간(23)에 파이롯트 작동레바(22)를 끼워 넣고 스프링(17')을 삽입후 스프링차단편(24)을 결합하여 보조편(26)이 있는 캠(25)을 설치한다.Then, the pilot valve 16 is inserted into the circular through hole 22 'of the pilot actuating lever 22, and the pilot actuating lever 22 is inserted into the lower one round protrusion 23, and the spring 17' is inserted into the spring. The blocking piece 24 is combined to install a cam 25 having an auxiliary piece 26.

이와 같이 조립한 밸브몸체(1) 상측에 안전캡(1')을 고정하여 유체실(33)을 만들고, 또 캠(25)의 보조편(26)에는 중력 상쇄용 보조부구(29)와 수위조절용 부구(28)가 삽입되고 조절가이드(30)가 끼워진 부구 안내봉(27)을 연동 결합한 레바(32)의 선단캠(31) 부분을 결합한 것이다.The safety cap 1 'is fixed to the upper side of the valve body 1 assembled in this way to make the fluid chamber 33, and the auxiliary piece 26 of the cam 25 has a gravity offset auxiliary outlet 29 and the water level. The adjusting buckle 28 is inserted and the adjustment guide 30 is coupled to the tip cam 31 of the lever 32 interlocked with the buckle guide rod 27 is fitted.

미설명 부호"34"는 공기구멍, "36"는 강수관, "A"는 상사점, "B"는 하사점이다.Reference numeral "34" denotes an air hole, "36" is a downcomer, "A" is a top dead center, and "B" is a bottom dead center.

이와 같이 된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention made as described above are as follows.

저수조내의 물(유체) 높이가 제 4 도와 같이 만수위일 경우 모든 작동은 정지가 된 상태에서 물의 사용으로 인한 저수조내의 수위가 낮아져 수위조절용 부구(28)가 부구안내봉(27) 하단의 중력상쇄용 보조부구(29)쪽에 도달하면 수위조절용 부구(28)의 무게가 작용하여 제 5 도와 같이 부구안내봉(27)이 레바(32)를 아래로 당기면 캠(31)이 위로 움직여 상사점(A)에 도달하면서 파이롯트 작동레바(22)를 밸브몸체(1) 내측으로 기울어지게 하면 스프링 차단편(24)에 의해 스프링(17')은 수축되고 원형통공(22')에 삽입되어 있던 파이롯트 밸브(16)가 비스듬히 밀려 스프링 눌름판(18) 하단의 스프링(17)이 수축되며 생긴 중간 차단편(14)과의 틈 사이로 유체실(33)에 충만된 압력에 제거되어 물은 스프링눌름판(18)의 유체 배출공(19)을 통해 피스톤(4) 중공부(7)로 흘러 외부로 배출된다.If the water (fluid) height in the reservoir is at full water level, such as the fourth degree, the water level in the reservoir is lowered due to the use of water while all operations are stopped, so that the water level adjusting float 28 is used for offsetting gravity at the bottom of the float guide rod 27. When the auxiliary ball (29) is reached, the weight of the water level adjusting float (28) acts, and as shown in FIG. 5, when the float guide rod (27) pulls the lever (32) down, the cam (31) moves upward to the top dead center (A). When the pilot actuating lever 22 is inclined to the inside of the valve body 1 while reaching the end, the spring 17 'is contracted by the spring blocking piece 24 and the pilot valve 16 inserted into the circular hole 22' is inserted. ) Is obliquely pushed so that the spring 17 at the bottom of the spring pressing plate 18 is contracted and the water is removed by the pressure filled in the fluid chamber 33 between the gaps with the intermediate blocking piece 14. Flow through the fluid outlet hole (19) to the hollow (7) of the piston (4) It is released.

이렇게 배출됨과 동시에 피스톤(4) 상판(5)과 하판(6) 사이에 정지되어 있던 물과 유입구(3) 측에서 들어오는 물이 상판(5)에 압력을 가중시켜 상측 유체실(33)쪽으로 피스톤(4)이 밀려 올라가면 밸브가 개방되어 아래의 저수조로 급수가 시작되는 것이다.At the same time, water discharged from the upper plate 5 and the lower plate 6 of the piston 4 and the water flowing in from the inlet port 3 increases pressure on the upper plate 5 and moves the piston toward the upper fluid chamber 33. When (4) is pushed up, the valve is opened and water supply starts to the reservoir below.

이때 피스톤(4)의 개폐를 공식으로 만들어 설명해 보면, 공급 유체의 압력을 "P"라 하고 상판(5) 상부면적을 "A1", 상판(5) 하부면적을 "A2", 하판(6) 상부면적을 "A3"라고 하면 설계시 상판(5)의 하부 면적이 하판(6)의 상부면적의 보다 넓게 제작하여 A2〉A3식으로 상판(5) 하부면적이 넓으므로 피스톤(4)을 들어올리게 하는 힘"PA2"로 이때의 힘 관계를 보면 PA2-PA3〉0가 되어 피스톤(4)은 안전캡(1')쪽으로 밀려 개방이 되는 것이다.At this time, the opening and closing of the piston (4) is described as a formula, the pressure of the supply fluid is "P", the upper area of the upper plate (5) "A1", the lower area of the upper plate (5) "A2", the lower plate (6) When the upper area is "A3", the lower area of the upper plate 5 is made wider than the upper area of the lower plate 6 in design, and the lower area of the upper plate 5 is wide in the formula A2> A3. In this case, PA2-PA3> 0, and the piston 4 is pushed toward the safety cap 1 'to open.

이렇게 유입되는 물은 대부분 하판(6) 아래의 강수관(35)을 지나 저수조에 모이나 일부는 거름망(12)을 지나 유입실(11)과 도압관(10)으로 유입되나 중간찬편(14)과 개방된 파이롯트밸브(16)의 공간 사이로 유입되어 중공부(7)를 지나 강수관(35)쪽으로 흐르게 된다.Most of the inflowing water flows through the precipitation pipe 35 under the lower plate 6 to the reservoir, but part of the water flows through the strainer 12 and into the inflow chamber 11 and the pressure guiding pipe 10, but the middle side section 14 and It flows into the space of the open pilot valve 16 and flows through the hollow portion 7 toward the downcomer 35.

이와 같이 계속되는 급수 시간의 흐름에 따라 수위가 상승하면 제 8 도와 같이 수위조절용 부구(28)는 부구안내봉(27)을 따라 상승하여 최고 수위점에 설치된 조절가이드(30)에 도달하여 점차 부구안내봉(27)도 상승하여 레바(32) 선단의 캡(31) 하사점(B)으로 되돌아 오면 스프링 차단편(24)에 의해 수축되어져 있던 스프링(17')이 복원되면서 스프링 누름판(18)에 수축되어 있던 스프링(17)이 팽창되면 파이롯트 작동레바(24)의 원형통공(22')에 삽입되어 기울어져 있던 파이롯트 밸브(16)가 원위치로 되돌아와 중간차단편(14)의 통공(14')을 차단하게 된다.As the water level rises as the water supply time continues, the water level adjusting float 28 rises along the float guide rod 27 to reach the adjustment guide 30 installed at the highest water level as shown in FIG. When the rod 27 also rises and returns to the bottom dead center B of the cap 31 at the tip of the lever 32, the spring 17 ', which has been contracted by the spring blocking piece 24, is restored to the spring pressing plate 18. When the retracted spring 17 is inflated, it is inserted into the circular through hole 22 'of the pilot actuating lever 24 and the inclined pilot valve 16 returns to its original position and the through hole 14' of the intermediate cut-off piece 14 is returned. ) Will be blocked.

이와 동시에 유입구(3)로 흐르던 유체가 거름망(12)을 통해 유입실(11)과 도압관(10)을 지나 조금씩 유입되는 물이 유체실(32)에 모여 압력이 가중되면 서서히 피스톤(4)이 아래로 내려가, 만수위가 되면 제 4 도와 같이 피스톤(4)의 하판(6)이 처음 위치인 밸브시트(2)에 닿으면 물의 흐름이 차단되는 것이다.At the same time, when the fluid flowing through the inlet 3 passes through the inlet chamber 11 and the pressure pipe 10 through the strainer 12, the water gradually flows into the fluid chamber 32, and when the pressure is increased, the piston 4 gradually. When the water level is lowered below this level, water flow is blocked when the lower plate 6 of the piston 4 reaches the valve seat 2, which is the first position as shown in the fourth drawing.

이렇게 닫히는 것을 앞서 설명한 공식으로 대비하여 보면 전체의 힘은 P(A1+A3)-PA2=P(A1+A3-A2)〉0가 되어 피스톤(4)이 닫히게 되는 것이다.In contrast to the closing formula described above, the total force is P (A1 + A3) -PA2 = P (A1 + A3-A2)> 0, which causes the piston 4 to close.

이와 같이 물이 유입실(11)을 지나 도압관(10)으로 흐르는 동안 거름망(12)에 의해 불순물을 걸러주며 보호링(13)을 거름망(12)을 고정하여 주며, 그리고 피스톤(4) 하판(6) 하부의 고무박킹(20)과 상판(5)외둘레링홈(8)에 끼워진 피스톤링(9)은 물위 누수를 막아주고, 하판(6)에 결합된 가이드(21)는 피스톤 (4)의 개폐시 물에 의해 피스톤(4)이 이탈되는 것을 막아주며, 상하 작동을 원활하게 하며 밸브몸체 하부에 만든 공기구멍(34)은 유체 공급이 중단 되었을 때 발생할지도 모르는 역류 형상을 방지하기 위한 사이폰 브레이크용이며 강수관(35)은 밸브가 열렸을 때 흐르는 물의 비산과 소음을 방지하기 위해 설치된 것이다.In this way, while the water flows through the inlet chamber (11) to the pressure pipe (10), it filters the impurities by the strainer 12, secures the strainer 12 to the protective ring 13, and the piston (4) the bottom plate (6) The piston ring (9) fitted in the lower rubber box (20) and the upper plate (5) outer circumferential ring groove (8) prevents water leakage, and the guide (21) coupled to the lower plate (6) is a piston (4). ) Prevents the piston (4) from being separated by water during opening and closing, and smoothly up and down operation, and the air hole 34 made in the lower part of the valve body to prevent the reverse flow shape that may occur when the fluid supply is interrupted The siphon brake is used for the precipitation pipe 35 to prevent the scattering and noise of flowing water when the valve is opened.

이와 같이 된 본 고안은 각종 건물등의 옥상 수조에 펌프로서 양수할 경우 펌프 토출배관에 간단한 입력위치를 하나 설치하므로서 펌프실내에서 급수시스템을 자동 제어할 수 있으므로 현재 사용되고 있는 전극봉방식 수위제어에서 오는 자동제어 공사비를 대폭 절감할 수 있으며, 특히 부전도성 유체의 액면 제어 및 경사지에 위치한 다수의 수조에 한 대의 펌프로서 급수가 가능한 경제적이고 실용적인 고안인 것이다.In this way, the present invention can automatically control the water supply system in the pump room by installing a simple input position in the pump discharge pipe when pumping pumps in rooftop water tanks of various buildings. It is possible to drastically reduce the cost of control construction, and it is an economical and practical design capable of supplying water as a pump for a plurality of tanks located in a liquid level control and a slope of nonconductive fluid.
