전자개방밸브를 이용한 건식 스프링클러 설비 {Dry sprinkler installation using solenoid valves}Dry sprinkler installation using solenoid valves}

본 발명은 건식 스프링클러 설비에 관한 것으로, 더욱 상세하게는 물을 공급하기 위한 1차측배관과, 공급된 물을 배출시켜 소화하기 단말에 복수개의 스프링클러가 구비된 2차측배관을 포함하고, 1차측배관과 2차측배관의 내부에 항상 가압수가 충수되어 있다가 화재발생시 열에 의해 스프링클러의 헤드가 개방되어 소화하는 건식 스프링클러설비에 있어서, 1차측배관과 2차측배관을 연결하는 전자개방밸브와, 상기 전자개방밸브의 일측에 2차측배관의 압력을 감지하는 압력스위치와, 상기 압력스위치의 작동을 감지하여 외부 스피커에 경고음을 송출하는 감시제어반을 구비하여, 화재발생시 열에 의해 스프링클러의 헤드가 개방되면 2차측배관의 내부에 충수된 물이 방수되고 압력이 낮아지고, 상기 압력스위치가 작동하면서 감시제어반이 이를 감지하여 1차측배관에 충수된 가압수가 2차측배관으로 유입되도록 전자개방밸브를 개방하고, 외부에 경보하는 것을 특징으로 하는 전자개방밸브를 이용한 건식 스프링클러 설비에 관한 것임.The present invention relates to a dry sprinkler facility, and more particularly, a primary side pipe for supplying water, and a secondary side pipe provided with a plurality of sprinklers in a terminal for discharging and extinguishing the supplied water, and the primary side pipe In a dry sprinkler facility in which pressurized water is always filled in the interior of the and secondary pipes, and the head of the sprinkler is opened and fired by heat in the event of a fire, an electromagnetic opening valve connecting the primary pipe and the secondary pipe, and the electromagnetic opening On one side of the valve, a pressure switch that senses the pressure of the secondary pipe and a monitoring control panel that detects the operation of the pressure switch and sends a warning sound to an external speaker is provided.When the head of the sprinkler is opened by heat during a fire, the secondary pipe The water filled in the inside of the unit is waterproofed and the pressure is lowered, and the monitoring control panel detects this as the pressure switch operates, opens the electronic opening valve so that the pressurized water filled in the primary pipe flows into the secondary pipe, and an alarm to the outside. It relates to a dry sprinkler facility using an electromagnetic opening valve, characterized in that.

일반적으로 대규모의 빌딩을 중심으로 소화용 스프링클러 헤드를 천정부에 배치한 스프링클러 장치가 보급되어 왔다.In general, sprinkler devices in which fire extinguishing sprinkler heads are disposed at the ceiling have been widely used around large-scale buildings.

종래의 상기 스프링클러 장치는 각각 독립적으로 주위의 열조건에 의해 작동하는 스프링클러 헤드, 물공급수단인 송수펌프 및 1차측 배관과 2차측 배관을 보유한 송수배관으로 구성된다.The conventional sprinkler device is composed of a sprinkler head that independently operates under ambient thermal conditions, a water supply pump serving as a water supply means, and a water supply pipe having a primary pipe and a secondary pipe.

상기 1차측 배관은 송수펌프로부터 각 플로어(floor)까지 수직방향으로 세워지도록 설치되어 있다. 또, 2차측 배관은 배관을 통해 물이 통과할 수 있도록 1차측 배관으로부터 분기되어, 각 플로어마다 대략 수평방향으로 연결되고 그 끝단에 스프링클러 헤드가 설치된다.The primary pipe is installed to be erected in a vertical direction from the water supply pump to each floor. In addition, the secondary pipe is branched from the primary pipe so that water can pass through the pipe, and is connected to each floor in a substantially horizontal direction, and a sprinkler head is installed at the end thereof.

이러한 스프링클러 장치는 크게 습식과 건식으로 구별된다. 전자는 1차측 배관뿐만 아니라 2차측 배관 내에도 물을 충전하고, 이것을 평상시 상태로 하지만, 후자는 1차측 배관에만 물을 충전하고 2차측 배관에는 물을 충전하지 않고 공기가 충만 한 상태로 되어 있다 점이 상이하다.These sprinkler devices are largely divided into wet and dry types. In the former, water is filled not only in the primary pipe but also in the secondary pipe, and this is in a normal state, but the latter is filled with water only in the primary pipe and the secondary pipe is not filled with water. The point is different.

종래의 습식 스프링클러 장치에서는 1차측 배관 내와 마찬가지로 2차측 배관 내에 충전된 물이 적정한 압력(예컨대7~8kgf/㎠정도)으로 유지되도록 함으로써, 화재가 발생하여 스프링클러 헤드가 작동한 때에는 신속하게 방수(放水)될 수 있게 한다.In the conventional wet sprinkler system, the water filled in the secondary pipe is maintained at an appropriate pressure (e.g., about 7 to 8 kgf/cm2) as in the primary pipe, so when a fire occurs and the sprinkler head is operated, it is quickly waterproof ( So that it can be rehydrated.

또한, 종래 습식 스프링클러 장치에서는 1차측 배관과 연결되는 압력유지장치가 별도로 구비되는데, 상기 압력유지장치는 보조펌프와 압력탱크로 구성되어, 1차측 배관내의 압력이 저하될 경우 상기 압력유지장치가 작동하여 1차측 배관에 물을 보충함으로써 적정한 압력이 유지될 수 있도록 한다.In addition, in the conventional wet sprinkler device, a pressure holding device connected to the primary pipe is separately provided, and the pressure holding device is composed of an auxiliary pump and a pressure tank, and the pressure holding device operates when the pressure in the primary pipe decreases. Thus, by replenishing water to the inlet pipe, the proper pressure can be maintained.

그런데, 상기 1차측 배관에서 2차측 배관으로 연결하는 건식 밸브는 기계적인 구성으로 인해 가격이 고가이므로 사용하기 어려운 단점이 있다.However, the dry valve connected from the primary pipe to the secondary pipe has a disadvantage that it is difficult to use because it is expensive because of its mechanical configuration.

It is characterized in that the electromagnetic opening valve is opened and the external alarm is alerted.

따라서, 본 발명에 따르면 화재발생시 열에 의해 스프링클러(21)의 헤드가 개방되면 2차측배관(20)의 내부에 충수된 물이 방수되고 압력이 낮아지고, 상기 압력스위치(31)가 작동하면서 감시제어반(40)이 이를 감지하여 1차측배관(10)에 충수된 가압수가 2차측배관(20)으로 유입되도록 전자개방밸브(30)를 개방하고, 외부에 경보할 수 있도록 구성됨으로써 고가의 기계적 장치에 대한 비용절감이 가능하여 가격 경쟁력을 향상시키고 재고유지 비용을 절감할 수 있게 되는 것이다.Therefore, according to the present invention, when the head of the sprinkler 21 is opened by heat when a fire occurs, the water filled in the secondary side pipe 20 is waterproof and the pressure is lowered, and the pressure switch 31 is operated, 40 detects this, opens the electromagnetic opening valve 30 so that the pressurized water filled in the primary pipe 10 flows into the secondary pipe 20, and is configured to alarm to the outside. It is possible to reduce the cost of the product, thereby improving price competitiveness and reducing inventory maintenance costs.
