The present invention relates to ready-operation fire extinguishing equipment using an electromagnetic valve which improves price competitiveness and reduces inventory maintenance costs. The ready-operation fire extinguishing equipment using an electromagnetic valve comprises a primary pipe to supply water and a secondary pipe having a plurality of closed sprinklers on a terminal to discharge supplied water to extinguish a fire. The ready-operation fire extinguishing equipment further comprises: an electromagnetic valve to connect the primary pipe and the secondary pipe; sensors arranged around the sprinklers; a manual operation box having an operating switch; and a monitoring control board to sense whether a fire occurs from the sensors and the operating switch to transmit a warning sound to an external speaker. The primary pipe is filled with pressurized water, and the secondary pipe is in an atmospheric state. At least two of the sensors detect a fire or a user operates the operating switch of the manual operation box to open the electromagnetic valve to transport the pressurized water accommodated in the primary pipe to the heads of the sprinklers of the secondary pipe. When the heads of the sprinklers are opened by heat, the pressurized water accommodated in the secondary pipe is released, and a warning is sent to the outside.

Description

전자밸브를 이용한 준비작동식 소화 설비 {Wet sprinkler installation using solenoid valves}Ready-to-operate fire extinguishing equipment using solenoid valves {Wet sprinkler installation using solenoid valves}

본 발명은 준비작동식 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 준비작동식 스프링클러설비에 있어서, 1차측배관과 2차측배관을 연결하는 전자밸브와, 상기 전자밸브의 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 전자밸브를 개방하고, 외부에 경보하는 것을 특징으로 하는 전자밸브를 이용한 준비작동식 소화 설비에 관한 것임.The present invention relates to a pre-operated sprinkler facility, and more particularly, comprises 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, 1 In a ready-to-operate sprinkler facility in which pressurized water is always filled in the inside of the secondary pipe and the secondary pipe, and the head of the sprinkler is opened and fired by heat in the event of a fire, an electromagnetic valve connecting the primary and secondary pipes; A pressure switch sensing the pressure of the secondary pipe at one side of the solenoid valve, and a monitoring control panel that detects the operation of the pressure switch and transmits a warning sound to an external speaker are provided.When the head of the sprinkler is opened by heat in case of fire, 2 The water filled in the inside of the secondary pipe is waterproofed and the pressure is lowered, and as the pressure switch operates, the monitoring and control panel detects this and opens the solenoid valve so that the pressurized water filled in the primary pipe flows into the secondary pipe. It relates to a ready-to-operate fire extinguishing facility using an solenoid valve characterized by an alarm.

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 건식과 준비작동식과 일제살수식으로 구별된다. 습식은 1차측 배관뿐만 아니라 2차측 배관 내에도 물을 충전하고, 이것을 평상시 상태로 하지만, 건식은 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, ready-to-operate and sprinkler systems. In the wet type, water is filled not only in the primary pipe but also in the secondary pipe, and this is in a normal state, but in the dry type, only the primary pipe is filled with water and the secondary pipe is filled with air without 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 밸브는 기계적인 구성으로 인해 가격이 고가이므로 사용하기 어려운 단점이 있다.However, the valve connecting from the primary pipe to the secondary pipe has a disadvantage that it is difficult to use because it is expensive due to its mechanical configuration.
