Description
본 고안은 소방시설용 압력챔버의 안전밸브에 관한 것으로서, 더욱 상세하게는 안전밸브를 통해 압력챔버에 잔존하고 있는 압축공기가 누설되는 것을 방지할수 있는 소방시설용 압력챔버의 안전밸브 설치구조에 관한 것이다.The present invention relates to a safety valve of a pressure chamber for fire fighting facilities, and more particularly to a safety valve installation structure of the pressure chamber for fire fighting facilities that can prevent the leakage of the compressed air remaining in the pressure chamber through the safety valve.
일반적으로, 물을 사용하는 소방화설비로는 옥내소화전 스프링 쿨러 포소화전 등이 있으며, 이들 설비는 화재발생시 소방용수를 이용하여 화재를 초기진압하는 설비이다.In general, fire-extinguishing facilities using water include indoor fire-fighting sprinklers and fire-fighting plants, and these facilities are used to extinguish a fire by using fire water for a fire.
특히, 스프링쿨러 설비는 화재발생시 이를 자동으로 감지하여 소화함과 동시에 경보기능을 가지므로 백화점, 시장, 호텔, 병원 등 다중이용시설 및 일정규모 이상의 건물 및 시설에 의무적으로 설치되고 있다.In particular, the sprinkler system automatically detects and extinguishes a fire and has an alarm function. Therefore, the sprinkler system is mandatory in multi-use facilities such as department stores, markets, hotels, hospitals, and buildings and facilities of a certain size or more.
상기와 같이 사용되는 소방설비는 펌프의 구동으로 저수조로부터 소방용수가 배관을 통하여 공급되고, 배관의 종단에 설치된 헤드의 개방으로 화재발생장소에 살수함으로써 소화하게 된다.Fire-fighting equipment used as described above is extinguished by supplying fire water from the water tank through a pipe driven by the pump, and spraying water in the fire place by opening the head installed at the end of the pipe.
화재발생 장소는 감지기 또는 감열용헤드에 의해서 화재를 인식하고 물이 화재장소에 살수되며, 이와 동시에 소방배관 및 압력챔버의 압력이 내려간다. 이렇게 내려간 압력을 압력챔버에 설치된 압력스위치가 인식하여 펌프를 가동시키게 된다.The location of the fire is recognized by the detector or the thermal head, and water is sprayed into the fire, and at the same time, the pressure of the fire pipe and the pressure chamber is lowered. This pressure is recognized by the pressure switch installed in the pressure chamber to start the pump.
이때, 압력스위치가 펌프를 기동하는 방식으로는 수동기동방식(ON-OFF 스위치방식)과 자동기동방식(기동용 수압 개폐장치방식)이 있으나 주로 후자인 자동기동방식이 채택되고 있으며, 상기와 같이 자동기동방식을 사용할 경우에는 도 1과 같이 압력챔버가 주요장비로 사용되고, 상기 압력챔버에는 압력스위치(10)가 설치되어 압력의 높고 낮음에 따라 펌프를 기동시키거나 정지시키게 된다.At this time, the pressure switch starts the pump as a manual start method (ON-OFF switch method) and automatic start method (starting hydraulic switchgear method), but the latter automatic start method is adopted, as described above In the case of using the automatic starting method, the pressure chamber is used as the main equipment as shown in FIG. 1, and a pressure switch 10 is installed in the pressure chamber to start or stop the pump according to the high and low pressure.
참고로, 펌프를 자동기동시키고, 규격방수 압력을 유지하며, 수격작용을 방지하는 압력챔버의 구성에 대해서 좀 더 상세히 설명하면, 도 1과 같이 직립 설치된 탱크(1)의 일측에 게이트밸브로 조작되는 인입구(2)가 설치되고, 상기 탱크(1)의 하단부에 배수구(3)가 설치되며, 상기 탱크(1)의 상부측에는 압력스위치(10) 및 압력계(5)가 설치된다.For reference, the configuration of the pressure chamber for automatically starting the pump, maintaining the standard waterproof pressure, and preventing water hammer, will be described in more detail, and operated as a gate valve on one side of the tank 1 installed upright as shown in FIG. 1. Inlet 2 is provided, the drain port 3 is provided at the lower end of the tank 1, the pressure switch 10 and the pressure gauge 5 is installed on the upper side of the tank (1).
그리고, 상기 탱크(1)의 상부에는 탱크 플랜지(6)가 설치되고, 상기 탱크 플랜지(6)에는 밸브 플랜지(7)가 볼트결합되는데, 상기 밸브 플랜지(7)의 정중앙에는 관통나사공(8)이 형성되어 이에 안전밸브(9)의 나사(9a)가 밀봉가능한 구조로 설치되어져 있다.In addition, a tank flange 6 is installed at an upper portion of the tank 1, and a valve flange 7 is bolted to the tank flange 6, and a through screw hole 8 is formed at the center of the valve flange 7. ) Is formed so that the screw (9a) of the safety valve (9) is installed in a sealable structure.
이때, 상기 안전밸브(9)의 용도는 펌프가동시 탱크(1)내에 이상압력이 발생되었을 때 탱크(1) 및 압력스위치(10)의 보호용으로 설치된 것이며, 이의 개방은 안전밸브(9)내의 스프링(9c)의 압축력보다 클 때 작동하게 된다.At this time, the use of the safety valve (9) is installed for the protection of the tank (1) and the pressure switch 10 when the abnormal pressure is generated in the tank (1) when the pump is running, the opening of the safety valve (9) It operates when it is larger than the compressive force of the spring 9c.
이때, 상기 안전밸브(9)는 이상압력이 발생하여 작동 이후에도 본래의 기능을 수행하여야 하나 탱크(1) 상부에 체류하여야 할 압축공기가 안전밸브(9)를 통해 누설되었다면 펌프가 기동할 때 수격작용에서 발생된 압력파로 인하여 펌프의 전기공급장치인 NFB나 마그네트에 영향을 주어 전기공급이 차단됨으로써 펌프가 차단되어 결과적으로 소화기능을 상살시키는 요인이 된다.At this time, the safety valve (9) has to perform the original function even after the operation of the abnormal pressure, but if the compressed air to be stayed on the tank (1) leaked through the safety valve (9) water hammer when the pump starts The pressure wave generated in the operation affects the NFB or magnet, which is the electric supply device of the pump, which cuts off the electricity supply, causing the pump to shut down and consequently destroy the digestive function.
상기와 같이, 종래에는 도 1과 같이 압축된 에어가 충진되어 있는 탱크(1)내의 상부측에 위치하고 있기 때문에 그 에어압력에 의해 안전밸브(9)의 미세한 틈새로 에어가 서서히 누설되므로서 탱크(1)내는 물이 채워지게 되어 펌프가 기동될 때 수격작용의 압력파로 인하여 압력스위치(10)가 빈번하게(펌프가 3초당 1회 정도로ON-OFF됨) 작동됨으로써 마그네트에 이상(마그네트 접점이 손상되거나 OCR 작동)이 발생함과 동시에 전기공급이 차단됨과 함께 펌프가 정지되어 소화기능을 상실하는 문제점이 있었다.As described above, since the air is conventionally located on the upper side in the tank 1 filled with the compressed air as shown in FIG. 1, the air pressure gradually leaks into the minute gap of the safety valve 9 due to the air pressure. 1) When the pump is started, the pressure switch 10 is operated frequently (the pump is ON-OFF about once every 3 seconds) due to the pressure wave of the water hammer when the pump is started. Or OCR operation) occurs and at the same time the electricity supply is cut off and the pump is stopped to lose the extinguishing function.
따라서, 본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로서 안전밸브의 주변에 에어차단관을 소정길이 연장하여 상기 에어차단관이 탱크내의 물속에 침수되게 하므로서 압력챔버에 잔존하고 있는 압축공기가 안전밸브를 통해 누설되는 것을 방지하고, 상기 압력챔버내에 항상 에어가 체류토록 하여 수격작용에 의한 압력스위치의 빈번한 오동작을 방지한 소방시설용 압력챔버의 안전밸브 설치구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above problems, and the compressed air remaining in the pressure chamber is secured by extending a predetermined length of the air shutoff tube around the safety valve so that the air shutoff tube is submerged in the water in the tank. It is an object of the present invention to provide a safety valve installation structure of a pressure chamber for a fire protection system which prevents leakage through a valve and prevents frequent malfunction of the pressure switch due to the water hammer action by allowing air to always stay in the pressure chamber.

이하, 본 고안의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail as follows.
도 2는 본 고안에 따른 압력챔버와 안전밸브의 분해사시도이고, 도 3은 본 고안에 따른 압력챔버에 안전밸브가 설치된 것을 보인 단면도이다.Figure 2 is an exploded perspective view of the pressure chamber and the safety valve according to the present invention, Figure 3 is a cross-sectional view showing that the safety valve is installed in the pressure chamber according to the present invention.
먼저, 압력챔버(100)는 직립 설치된 탱크(110)의 일측에 게이트밸브에 조작되는 인입구(120)가 설치되고, 상기 탱크(110)의 하단부에는 배수구(130)가 설치되며, 상기 탱크(110)의 상부측에는 압력스위치(180) 및 압력계(150)가 설치된다.First, the pressure chamber 100 has an inlet 120 manipulated to a gate valve at one side of the tank 110 installed upright, and a drain port 130 is installed at the lower end of the tank 110, and the tank 110. At the upper side of the pressure switch 180 and the pressure gauge 150 is installed.
그리고, 상기 탱크(110)의 상부에는 탱크 플랜지(160)가 설치되고, 상기 탱크 플랜지(160)에는 밸브 플랜지(170)가 볼트결합되는데, 상기 밸브 플랜지(170)에 안전밸브(190)의 나사부(191)와 대응되는 나사공(171)을 형성한 다음, 상기 밸브 플랜지(170) 저면의 나사공(171)에 그 단부가 탱크(110)내의 저장된 물속으로 침수될 수 있게 에어차단관(172)을 연장하여 용접한다. 즉, 에어만 들어 있는 탱크(110)내에 물을 충진하게 되면 도 3과 같이 그 내부에 물이 차면서 그 내부에 잔존하고 있던 에어가 압축되며, 이때 소정압력으로 충입된 물은 압축된 에어에 의해 일정 수위를 유지하게 되므로 에어차단관(172)의 단부가 이 물에 침수될 시에는 압축된 에어가 안전밸브(190)로 역류하지 못하게 된다.In addition, a tank flange 160 is installed at an upper portion of the tank 110, and a valve flange 170 is bolted to the tank flange 160, and a threaded portion of the safety valve 190 is connected to the valve flange 170. After forming the screw hole 171 corresponding to the 191, the air blocking tube 172 so that the end of the screw hole 171 of the bottom of the valve flange 170 can be submerged into the stored water in the tank 110 Weld by extension). That is, when water is filled in the tank 110 containing only air, the air remaining in the inside of the water is compressed as shown in FIG. 3, and the water filled at the predetermined pressure is compressed by the compressed air. Since a certain level is maintained, compressed air may not flow back to the safety valve 190 when the end portion of the air blocking tube 172 is submerged in the water.
그리고, 상기 에어차단관(172)은 밸브 플랜지(170)와 일체로 형성하여도 되나 상기 밸브 플랜지(170)에 에어차단관(172)을 용접 결합하다.The air shutoff tube 172 may be integrally formed with the valve flange 170, but the air shutoff tube 172 is welded to the valve flange 170 by welding.
상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
먼저, 상기 탱크(110) 상부의 탱크 플랜지(160)에 밸브 플랜지(170)를 다수의 볼트로서 밀봉가능하게 결합시키는데, 이때 상기 밸브 플랜지(170) 저부의 에어차단관(172)이 탱크(110) 내부로 위치하도록 한 다음, 밸브 플랜지(170)의 나사공(171)에 안전밸브(190)의 나사부(191)를 밀봉가능하게 체결한다.First, the valve flange 170 is sealably coupled to the tank flange 160 on the upper part of the tank 110 as a plurality of bolts, wherein the air blocking tube 172 at the bottom of the valve flange 170 is connected to the tank 110. ) And then sealably fasten the threaded portion 191 of the safety valve 190 to the threaded hole 171 of the valve flange 170.
그런 다음, 상기 탱크(110)의 인입구(120)를 통해 그 내부로 물을 공급하게 되면, 탱크(110) 내부로 물이 차 오르게 되는데, 이때 탱크(110) 내부에 잔존하고 있던 에어가 압축되어 탱크(110)의 내측 상부에 집중된다.Then, when water is supplied to the inside through the inlet 120 of the tank 110, the water rises into the tank 110, wherein the air remaining in the tank 110 is compressed It is concentrated in the inner upper part of the tank 110.
이와 동시에, 밸브 플랜지(170) 저부의 에어차단관(172) 하단이 일정한 수위를 유지하고 있는 물 속에 침수되므로서 안전밸브(190)가 고압의 에어와 접촉되는 것이 방지되어 에어누설로 인한 압력스위치의 빈번한 오동작이 방지되는 것이다.At the same time, the lower end of the air shutoff tube 172 at the bottom of the valve flange 170 is immersed in water maintaining a constant water level, thereby preventing the safety valve 190 from contacting with high pressure air, thereby causing a pressure switch due to air leakage. Frequent malfunctions are prevented.
따라서, 본 고안은 안전밸브(190)가 설치되는 밸브 플랜지(170)의 나사공(171) 하부에 에어차단관(172)을 소정길이 연장하여 상기 에어차단관(172)이 탱크(110)내의 물 속에 침수되게 하므로서 압력챔버(100)에 잔존하고 있는 압축공기가 안전밸브(190)를 통해 누설되는 것을 방지하고, 상기 압력챔버(100)내에 항상 에어가 체류토록 하여 수격작용에 의한 압력스위치의 빈번한 오동작을 방지한 매우 유용한 효과가 있다.Therefore, the present invention extends the air shutoff tube 172 to a predetermined length in the lower portion of the screw hole 171 of the valve flange 170 in which the safety valve 190 is installed, so that the air shutoff tube 172 is disposed within the tank 110. By submerging in water, the compressed air remaining in the pressure chamber 100 is prevented from leaking through the safety valve 190, and the air always stays in the pressure chamber 100, so that the water pressure switch There is a very useful effect of preventing frequent malfunctions.
