Description

배관용 스트레이너 구조{TRAINER ESTABLISHMENT STRUCTURE FOR WATERWORKS PIPING} TRAINER ESTABLISHMENT STRUCTURE FOR WATERWORKS PIPING}

본 발명은 배관용 스트레이너 구조에 관한 것으로, 더욱 상세하게는 상하수도용 배관 연결구의 유입구와 유출구 사이에 형성되되 배관을 통과하는 유체의 흐름을 방해하지 않으면서 유체 속의 이물질의 제거는 용이하게 할 수 있는 배관용 스트레이너 구조에 관한 것이다.
The present invention relates to a strainer structure for piping, and more particularly, it is formed between the inlet and outlet of the pipe connection for water and sewage, which can facilitate the removal of foreign substances in the fluid without disturbing the flow of the fluid through the pipe. It relates to a pipe strainer structure.

일반적으로, 상하수도관 배관라인에는 스트레이너를 설치하여 이물질의 유입을 방지하게 된다. 특히 상수원으로부터 수돗물을 공급하는 배관 중간에는 계량기가 설치되는데 상기 계량기의 전단부에 계량기를 보호하고, 유체 속에 포함된 이물질을 걸러내기 위한 장치로서 스트레이너가 설치된다.In general, water and sewage pipe line to install a strainer to prevent the inflow of foreign matter. In particular, a meter is installed in the middle of the pipe for supplying tap water from the water supply. A strainer is installed as a device for protecting the meter at the front end of the meter and filtering out foreign substances contained in the fluid.

상기와 같은 스트레이너는 배관 상에 유동되는 유체의 종류나 배관설비의 특성에 맞춰 선택되어 설치되는데, 종래의 스트레이너(10)는 도 1에 도시한 바와 같이 유체가 유입 및 배출되는 유입구(15) 및 배출구(14)가 수평으로 설치되고 하방으로 경사지게 여과망설치부(13)가 돌출된 스트레이너 몸체(16)와, 상기 여과망설치부(13)의 하부를 통해 삽입되어 설치되고 대략 원통형의 몸체에 다수 개의 통공이 천공된 여과망(11)으로 구성된다. The strainer as described above is selected and installed according to the type of fluid flowing on the pipe or the characteristics of the piping equipment, the conventional strainer 10 is shown in Figure 1 inlet and fluid inlet and outlet 15 and The outlet 14 is installed horizontally and the strainer body 16 protruding downwardly inclined downwardly and the filter net installation portion 13, and inserted through the lower portion of the filter net installation portion 13 is installed in a plurality of substantially cylindrical body The through hole is composed of a perforated filter net (11).

상기 스트레이너 몸체(16)는 삼방향으로관가 형성되어 상호 체결되는 구조로, 하방(下方)관(13)를 통해 여과망(11)이 삽입되고, 여과망(11)이 뚜껑체(12)와 삽입밀착되는 구조를 갖는다. 따라서 전방 유입구(14)를 통해 공급되는 유체는 여과망의 외주면에 형성된 통공들을 통해 이물질이 걸러진 상태로 후방 배출구(15)를 통해 배출되어 진다.
The strainer body 16 has a structure in which the tubes are formed in three directions to be fastened to each other, and the filtering net 11 is inserted through the lower tube 13, and the filtering net 11 is inserted into the lid body 12. It has a structure. Therefore, the fluid supplied through the front inlet 14 is discharged through the rear outlet 15 while the foreign matter is filtered through the through holes formed in the outer peripheral surface of the filtering network.

그러나 종래의 상기 스트레이너는 여과망이 원통형상이고, 또한 하방관 내부에 여과망이 형성되는 구조여서 전방 유입구를 통해 유입되는 유체가 하방관를 거친 다음 여과망의 통공을 통과하여 후방 배출구로 배출됨으로 인해 유체의 흐름이 연속적이지 못하게 된다.However, in the conventional strainer, the filter net has a cylindrical shape, and the filter net is formed inside the downcomer so that the fluid flowing through the front inlet passes through the downcomer and then passes through the through of the filter net to be discharged to the rear outlet. It is not continuous.

또한 유체의 속도가 순간적으로 감속되면서 여과망의 외주면에는 이물질들이 쉽게 쌓이게 되고 통공이 막히게 되면서 여과망은 그 기능을 상실하게 된다. In addition, as the speed of the fluid decelerates momentarily, foreign matter easily accumulates on the outer circumferential surface of the filtering network, and as the through hole is blocked, the filtering network loses its function.

이로 인해 종래의 스트레이너는 자주 여과망의 이물질을 제거해 주어야 하며, 이를 소홀히 할 경우 상수도관 및 주변 밸브 등과 같은 주변 기기의 파손을 초래하는 단점을 갖는다.
For this reason, the conventional strainer has to frequently remove foreign substances in the filtering network, and if this is neglected, it has a disadvantage of causing damage to peripheral devices such as water pipes and peripheral valves.

이를 위해 본 발명은 유체유입관와 유체배출관는 수평으로 형성되고 상기 유체유입관와 유체배출관 하방에는 유체배출관 방향을 향해 경사지게 이물질배출관가 형성되는 스트레이너 몸체와, 상기 유체유입관와 유체배출관의 사이에 형성되는 경사면과, 상기 경사면에 결합되고 타원의 평판형상인 여과망과, 상기 유체배출관 상부에 여과망을 향해 고압의 물을 분사할 수 있도록 하기 위한 역세분사관과, 상기 역세분사관에 고압의 물을 공급하기 위한 펌프로 이루어짐을 특징으로 하는 배관용 스트레이너 구조를 제공하기 위한 것이다.To this end, the present invention is a fluid inlet pipe and the fluid discharge pipe is formed horizontally and the strainer body is formed in the foreign material discharge pipe inclined toward the fluid discharge pipe direction below the fluid inlet pipe and the fluid discharge pipe, the inclined surface formed between the fluid inlet pipe and the fluid discharge pipe, A filter network coupled to the inclined surface and having a flat ellipse shape, a backwashing pipe for injecting high pressure water onto the fluid discharge pipe, and a pump for supplying high pressure water to the backwashing pipe. It is to provide a strainer structure for piping characterized in that made.

이처럼 본 발명은 유체유입관와 유체배출관가 수평, 즉 일직선으로 형성되므로 유체유입관를 통해 유입되는 유체가 방향의 꺾임 없이 자연스럽게 유체배출관를 통해 배출되므로 신속한 유체의 배출이 가능하고, 또한 상기 유체와 함께 유입된 이물질은 유체의 흐름방향과 경사지게 형성된 여과망에 의해 이물질배출관로 배출되도록 함으로서 이물질에 의한 여과망 막힘을 방지하도록 하는 효과를 갖는다.As described above, since the fluid inlet pipe and the fluid discharge pipe are formed horizontally, that is, in a straight line, the fluid flowing through the fluid inlet pipe is naturally discharged through the fluid discharge pipe without breaking in the direction, thereby enabling the rapid discharge of the fluid, and also the foreign matter introduced with the fluid. The silver is discharged to the foreign matter discharge pipe by the filter net formed inclined with the flow direction of the fluid has the effect of preventing the clogging of the filter network by foreign matter.

또 본 발명은 여과망이 유체의 흐름방향을 꺾지 않게 되어 유체의 흐름을 따라 자연스럽게 이물질이 아래로 배출되며, 또한 유체배출관 상부에 여과망을 향해 고압의 물을 분사할 수 있도록 하기 위한 역세분사관에 의해 여과망에 걸려있거나 끼어있던 이물질들을 쉽게 제거할 수 있어 청소가 용이한 매우 유용한 발명인 것이다.
In addition, the present invention is not filtered by the filter net flow direction of the foreign matter is naturally discharged downward along the flow of the fluid, and also by the back-spray pipe for injecting a high-pressure water toward the filter net on the top of the fluid discharge pipe It is a very useful invention that is easy to clean because it can easily remove foreign substances stuck or caught in the filter net.
