본 발명은 지하수용 수중 모우터를 시동시킬 때에 생기는 순간적인 충격 압력을 완충되게 하는 동시에 정지 되었을 때는 자율 배수되게 하는 방법이다.The present invention is a method for buffering the instantaneous impact pressure generated when starting a submersible motor for groundwater and at the same time autonomously draining when stopped.

일반적으로 지하수용 수중 모우터는 지하의 심부에서 높게 양수(50-300m)를 하는 것이나, 그 형태가 긴 봉체로 형성된 것을 지중에 세우고 지하수를 수직상으로 양수하기 때문에 강력한 시동 양수력이 필요로 하나, 한편 모우터에 시동스위치를 넣는 순간에는 양수되는 순간 수압(30kg/cm)이 크게 발생하며, 이 순간 수압에 의하여 토출관에 설치된 각종의 계량기와 첵벨브 등 중요부설물을 쉽게 파손시키는 폐단이 있다. 따라서, 본 발명인은 극히 간단한 구조물의 물리적 성질을 이용하여 취급의 간편과 작용의 완벽을 기할 수 있게 되는 완충방법을 제공하려 한다.In general, groundwater submersible motors are highly pumped (50-300m) deep in the basement of the ground, but strong starting pumping power is required because the groundwater is pumped vertically while the ground is formed of a long rod. On the other hand, when the start switch is put into the motor, the water pressure (30kg / cm) is greatly generated at the time of pumping, and at this moment, there is a closed end that easily breaks important installations such as various meters and check valves installed in the discharge pipe. . Therefore, the present inventors are trying to provide a buffer method that can achieve the ease of handling and perfection of action by using the physical properties of the extremely simple structure.

본 발명의 구성을 첨부 도면에 의하여 상술하면 모우터(1)의 배수관 상단부에 원통형의 보조밸브실(2)과 구형체의 주밸브실(3) 및 토출관(4)을 연설하여 보조밸브실(2)의 내부 하단층에는 받침돌기(5)를 수개 돌설하고 보조밸브실(2)의 내경보다 작은 직경으로 된 보조구변(6)을 보조밸브실(2)내에 수용하되 이 보저구변(6)은 분출되는 물의 일부를 통과시키는 상태에서 받침돌기(5)상에 탑승되며 주밸브실(3)내에는 종과 횡방향으로 통수작용을 하는 배수세공(7)(7')을 천공한 중량구변(8)을 수용하여 물의 상승력과 자체 중량에 의하여 통수관로를 개폐작동되게 한 것으로서, 도면중 9는 에어핀, 10은 압력계, 11은 첵크밸브를 표시한 것이다.The configuration of the present invention will be described in detail with reference to the accompanying drawings, and the cylindrical auxiliary valve chamber 2, the spherical main valve chamber 3 and the discharge tube 4 are extended to the upper end of the drain pipe of the motor 1, and the auxiliary valve chamber ( In the lower inner layer of 2), a plurality of support protrusions 5 protrude and the auxiliary valve 6 having a diameter smaller than the inner diameter of the auxiliary valve chamber 2 is accommodated in the auxiliary valve chamber 2, but the bottom valve 6 is supported. Is loaded on the support protrusion 5 in the state of passing a part of the water discharged, and the weight variation in the drainage holes 7 and 7 'which is a water-permeating action in the longitudinal and transverse directions in the main valve chamber 3 ( 8) to accommodate the opening and closing operation of the water supply pipe by the lifting force and the weight of the water, in the figure 9 is an air pin, 10 is a pressure gauge, 11 is a check valve.

본 발명의 작용효과를 설명하면 주밸브실(3)의 하부에 설치된 보조밸브실(2)내에는 보다 작은 보조구변(6)을 수용하였으므로 모우터(1)스위치를 넣으면 그 회동력에 의하여 물이 순간적으로 압상되며, 이때 보조구변(6)은 수압으로 상승하여 상부의 중량구벽(8)에 충돌되는 힘과 수압으로 중량구변(8)을 열게하여 토출관(4)을 연통되게 하는 것으로써, 이때 토출관(4)을 통과하는 순간 수압은 일차적으로 보조구변(6)에 의해 일부약화되면서 그 상부의 중량구변(8)을 압상시키면서 통과할 때 2차적으로 약화되므로 순간적인 수압은 약화된 상태에서 흡상된 물은 계속하여 토출관(4)으로 배수되는 바, 중량구변(8)에는 종과 횡방향으로 배수세공(7)(7')이 있으므로 모우터(1)을 운영하는 과정에서 정전이나 점검때에 모우터(1)회전을 중단시키면 토출관(4)축에 수용되었던 물은 중량구변(8)의 폐쇄상태에서도 어느 일방측 세공(7)(7')을 통과하여 하부로 서서히 흘러내린다.When explaining the operation and effect of the present invention, the auxiliary valve chamber (2) installed in the lower portion of the main valve chamber (3) accommodated the smaller auxiliary valve (6), so that when the switch of the motor (1) is inserted into the water by the rotational force It is instantaneously squeezed, in which the auxiliary sphere 6 rises with water pressure to open the weight sphere 8 with a force and pressure that collides with the upper weight sphere wall 8 so that the discharge pipe 4 is in communication. At this time, the instantaneous water pressure passing through the discharge pipe 4 is first weakened by the secondary sphere 6, and the second pressure is weakened when passing while pressing the weight sphere 8 of the upper portion, the instantaneous water pressure is weakened. Since the water sucked in the water is continuously drained to the discharge pipe 4, the weight section 8 has drainage holes 7 and 7 ′ in the longitudinal and transverse directions, so that the power failure during the operation of the motor 1 is performed. When the motor (1) stops rotating at the time of inspection or inspection, it is accommodated in the discharge pipe (4) shaft. The water that had flowed down slowly to the bottom side through the one-way orifice (7) (7 ') which in the closed state of the weight gubyeon 8.

이와같은 구성이므로 극히 단조로운 2개의 구형변에 의하여 충격압력을 완화시켜 계량기나 압력계(10) 등의 기계적 안전도를 높이게 한 것이다.Because of this configuration, the shock pressure is relaxed by two extremely monotonous edges to increase the mechanical safety of the meter or pressure gauge 10 and the like.
