제4도는 일부가 절개된본 고안의 조립예시도.Figure 4 is an assembly example of the present invention is a part cut.
본 고안은 관정(管井)용 양수 펌프의 역지변의 개량에 관한 것이며, 특히 구조가 간단하면서도 펌프 가동이 중지된 상태에서 펌프내의 물이 관정속으로 역류되지않게 하는 기능이 강화된 새로운 역지변의 구조에 관한 것이다.The present invention relates to the improvement of the reverse displacement of a well pump for pipe wells, and in particular, a simple reverse structure and a new reverse displacement enhanced function to prevent the water in the pump from flowing back to the pipe flow speed while the pump is stopped. It's about structure.
관정용 양수 펌프에 있어서의 역지변은 그 설치위치에 따라 체크밸브 또는 푸트 밸브라고도 불리는 것으로서, 펌프가동에 의하여 지하수를 퍼올릴때에는 변판이 수로를 개방하므로서 양수가 되지만 일단 펌프의 가동이 중지된 후에는 그즉시 변판이 수로를 차단하여 펌프내에 이미 들어차있던 물이 관정속으로 역류되지 않도록 방지하는 기능을 갖는 것이다.Reverse check in the pump for pumping well is also called check valve or foot valve depending on the installation position. When pumping groundwater by pump operation, the valve is pumped by opening the channel, but once the pump is stopped The valve immediately has the function of blocking the channel so that the water already in the pump does not flow back into the pipe velocity.
만약, 펌프내의 물이 역류될때 급수전을 잠그지않으면 급수된 물이 모두 빠져버리는 경우가 있으며, 이로인해 펌프내에는 물이없어 자흡이 이루어지지않으므로 이후 재양수시펌프의 기능이 마비되는 중대한 영향을 끼치게 된다.If the water supply in the pump is not reversed, if the water supply is not locked, all of the water supply may fall out, and thus there is no water in the pump so that no self-absorption occurs. .
따라서 역지변의 기능은 매우 중요하다.Therefore, reverse function is very important.
종래의 관정용 양수 펌프는 반드시 흡입 플랜지와 플랜지용 패킹을 필요로 하고 있다.Conventional well pumps require a suction flange and a flange packing.
제1도에 표시된 역지변은 종래의 대표적인 역지변의 구조를 나타낸것인데, 이 그림에서 보듯이 몸체(2)와 공기실(1)에 발청되지 않도록한 황동제 밸브시이트 (7)를 끼우고, 또한 시이트(7)와 변판(5)사이에 합성고무등의 탄성재로된 쿠션(6)을 끼워 조이며, 변판(5)이 항상 폐쇄방향으로 작용하도록 하는 압축코일 스프링 (4)을 상기변판(5)의 이면에 설치하고, 이 스프링(4)의 타단 변체(1)상에서 변판 (5)의 이면쪽에 나사끼움한 덮개(3)의 내면에 눌리도록한 것이다.The reverse displacement shown in FIG. 1 shows the structure of a conventional representative reverse displacement. As shown in this figure, a brass valve seat 7 is inserted into the body 2 and the air chamber 1 so as not to be rusted. In addition, between the sheet 7 and the side plate 5 is fitted with a cushion 6 made of an elastic material such as synthetic rubber, and the compression coil spring (4) for the side plate 5 to always act in the closing direction, the side plate ( It is provided in the back surface of 5), and it is made to press on the inner surface of the cover 3 screwed on the back surface side of the side plate 5 on the other end body 1 of this spring 4.
이러한 구조를 가진 종래의 역지변을 그 구성 부품수가 많고 조립공수도 여러 단계를 거치는 만큼 제조원가가 상당히 높은 결점이 있다.The conventional reverse displacement having such a structure has a drawback that the manufacturing cost is considerably high as the number of components is high and the number of assembling work goes through several steps.
본 고안은 상기한 결점을 갖지 않는 새로운 양수펌프용 역지변을 제공하기 위해 창안된 것으로서 제2도 이하의 첨부 도면을 참조하여 본 고안의 구조와 작용효과에 대하여 상세히 설명한다.The present invention was devised to provide a reverse pump for a new pump having no drawbacks as described above, and the structure and effect of the present invention will be described in detail with reference to the accompanying drawings of FIG. 2.
고강도 합성수지를 사출하여 성형한 흡입측 플랜지(8)에 있어서 연결측 플랜지(10)와 마주보는 면의 일측에 변판(9)의 고정부측에 형성한 돌기(9b)용 끼움홈 (8b)과 연결측 플랜지(10)에서 흡입측 플랜지(8)를 향하는 면의 일측에 돌출시킨 돌기(10a)용 끼움홈(8a)을 형성하고, 상기 흡입측 플랜지(8)의 변좌(8c)를 상기 홈(8a)(8b)쪽으로 기울어지게 구배시키며, 원형 변판(9)은 고무재로하고 그 내부에 형성한 중공부에다가 경질합성수지나 금속 따위로된 보강제(9a)를 매입하여, 이 변판(9)의 주위에 이것과 일체상으로되고 이들간에 C형 홈이 남도록 고정환테(9c)를 형성하여 상기 돌기(9b)와 함께 변판(9) 전체의 고정자세가 안정되게하고, 상기 연결측 플랜지(10)의 이면에 오링(11)의 돌기(11a)용 끼움홈(10b)을 형성하여 이룬 역지변을 구조적 특징으로한 것이다.In the suction side flange 8 formed by injection-molding high-strength synthetic resin, it is connected to the fitting groove 8b for the projection 9b formed on the fixing part side of the side plate 9 on one side of the surface facing the connection side flange 10. A fitting groove 8a for the projection 10a is formed on one side of the surface facing the suction side flange 8 from the side flange 10, and the toilet seat 8c of the suction side flange 8 is formed in the groove ( 8a) is inclined toward 8b, and the circular stools 9 are made of rubber material and hollow parts formed therein are embedded with a hard synthetic resin or metal reinforcing agent 9a. The fixed ring frame 9c is formed so as to be integral with this and the C-shaped groove is left therebetween, so that the fixed posture of the whole side plate 9 together with the protrusion 9b is stabilized, and the connection side flange 10 is formed. On the back surface of the O-ring 11 is formed by the fitting groove 10b for the projection (11a) is characterized by the reverse displacement achieved by the structural.
이와같이 구성된 본 고안에 있어서 제5도에 표시된 바와같이 흡입측 플랜지 (8)의 내측 끼움 홈(8b)에는 변판(9)의 돌기(9b)를 그리고 외측끼움홈(8a)에는 연결측 플랜지(10)의 돌기(10a)를 각각 끼워 넣어 조립한 다음 연결측 플랜지 (10)의 이면에 있는 끼움홈(10b)에는 오링(11)의 돌기(11a)를 끼워 맞추고 이어서 이 오링(11)의 이면쪽에 관정쪽에 접한 변체의 유입구축(12)을 맞댄다음 보울트로 체결하여 조립하며 이렇게 조립상태에서의 변판(9)은 변판(8c)의 구배면을 막아 유로를 폐쇄한 상태를 유지하다가 펌프로 이동되면 그 흡입력에 의하여 변좌(8c)에서부터 떨어져 유로를 개방하게 된다.In the present invention configured as described above, as shown in FIG. 5, the protrusion 9b of the side plate 9 is provided on the inner fitting groove 8b of the suction side flange 8, and the connecting flange 10 is connected to the outer fitting groove 8a. Assemble each of the projections (10a) of the) and then fit the projections (11a) of the O-ring (11) to the fitting groove (10b) on the rear side of the connecting flange (10) and then to the rear side of the O-ring (11) After the inlet shaft 12 of the body facing the pipe side is fastened and assembled with a bolt, the side plate 9 in the assembled state blocks the slope of the side plate 8c to maintain the closed state of the flow path and then moves to the pump. The flow path is opened from the toilet seat 8c by the suction force.
변좌(8c)가 막혀 있을때에는 변좌(9)이 변좌(8c)의 구배도만큼 기울어져 있어서 이 기울기에 상용하여 변좌(8c)에 대해 탄력을 갖고 폐쇄하게 되며 더우기 유로가 개방된 경우에는 이러한 변판(9)의 기울기는 더욱커져 탄력이 증가한다.When the toilet seat 8c is blocked, the toilet seat 9 is inclined by the gradient degree of the toilet seat 8c, and it is used at this inclination to close and resiliently close to the toilet seat 8c. The slope of (9) becomes larger and the elasticity increases.
그리하여 개방후 유로를 폐쇄하는 방향으로 움직일때 그 동작은 탄력에 힘입어 강력하게 그리고 신속하게 이루어지고 따라서 펌프속에 유입되어있는 물이 역류방지에 큰 효과가 나타난다.Thus, when moving in the direction of closing the flow path after opening, the action is made strongly and quickly by the elasticity, so that the water flowing into the pump has a great effect on preventing backflow.
또한 이 변판(9)은 고무제에서 신축성을 갖고 있으나, 그 내부에 매입된 보강재(9a)에 의해 보강되므로서 면방향으로 작용하는 수압에도 형상에 변화가 일어나지않아 기능 발휘에 지장을 받는 일은 없다.In addition, the swash plate 9 has elasticity made of rubber, but it is reinforced by the reinforcing material 9a embedded therein, so that the shape does not change due to the water pressure acting in the surface direction and does not interfere with the functioning. .
이상과 같은 본 고안에 의하면 변판 자체의 구조가 단순한 데다가 폐쇄작용을 돕는 압축 스프링의 배재되고 이에 상응하는 탄력이 변판 자체에 부여되어 결과적으로 역지변의 구조 단순화가 이룩되고 이에 따라 조립 공정수도 감축되여 이로써 양수 펌프용 역지변의 제조단가도 대폭 절감되는 등의 효과가 있다.According to the present invention as described above, the structure of the slab itself is simple, and the compression spring assisting the closing action and the corresponding elasticity are given to the slab itself, resulting in a simplified structure of reverse displacement, thereby reducing the number of assembly processes. As a result, the manufacturing cost of the reverse valve for pumping pump is also greatly reduced.
