저장탱크용 안전밸브{SAFETY VALVE FOR STORAGE TANK}Safety valve for storage tank {SAFETY VALVE FOR STORAGE TANK}

본 발명의 저장탱크용 안전밸브에 관한 것으로 상세하게는 각종 저장조 또는 저장탱크에 설치하여 내부 압력을 간편하게 조절할 수 있도록 함과 동시에 원활하게 배출공기를 필터링하도록 하는 저장탱크용 안전밸브에 관한 것이다.The present invention relates to a safety valve for a storage tank, and more particularly, to a safety valve for a storage tank that is installed in various storage tanks or storage tanks to easily control the internal pressure and to smoothly filter exhaust air.

일반적으로 생활폐수 등의 오·폐수를 저장하는 합성수지제의 저장탱크에는 압력방지밸브를 결합하여 내부에 압력변화에 내부의 공기를 자동으로 배출하여 내부의 압력을 일정이하의 압력상태를 유지하도록 하였다.In general, a synthetic resin storage tank that stores waste water such as domestic wastewater is combined with a pressure preventing valve to automatically discharge the air inside due to a pressure change to maintain the pressure inside the pressure. .

이러한 종래의 기술은 단순히 압력을 배출하므로 다양한 오·폐수로부터 발생하는 악취 등도 함께 외부로 배출시키므로 주변 공기를 오염시킬 생활에 불편함을 발생시켰다.Since the conventional technology simply discharges pressure, the odor generated from various waste water and waste water is also discharged to the outside, thereby causing inconvenience in living to contaminate the surrounding air.

더불어, 펌프운전으로 저장탱크를 펌핑할 때 저장탱크의 내부에서 저압이 심하게 발생하여 원활한 펌핑 작업을 방해하여 작업효율을 크게 저하시키는 문제점이 있었다.In addition, when pumping the storage tank by pump operation, there is a problem in that low pressure is generated in the interior of the storage tank, which hinders the smooth pumping operation and significantly lowers the working efficiency.

따라서 이러한 종래의 기술로 인하여 저장탱크 내의 고압력이나 저압력을 상태를 동시에 컨트롤하도록 함과 동시에 악취 발생을 억제하는 새로운 기술의 개발이 지속적으로 요구되어 왔다.Therefore, due to such a conventional technology, it has been continuously required to develop a new technology that simultaneously controls the state of high pressure or low pressure in the storage tank and suppresses the occurrence of odor.

종래기술로는 국내특허등록 제10-0754134호 및 국내특허공개 제10-2019-0066475호 등이 있다.Prior arts include Korean Patent Registration No. 10-0754134 and Korean Patent Publication No. 10-2019-0066475.

It is to provide a safety valve for a storage tank.

본 발명의 다른 목적은 저장탱크의 펌프 운전 등으로 인한 저압발생시 원활하게 외부공기를 공기를 흡입하여 펌핑효율을 향상시킬 수 있도록 하는 저장탱크용 안전밸브를 제공하는 데 있다.Another object of the present invention is to provide a safety valve for a storage tank that can improve the pumping efficiency by smoothly inhaling external air when low pressure occurs due to pump operation of the storage tank.

A high-pressure valve is coupled to the high-pressure exhaust port of the main body and the main body to open the air as the pressure rises, and an air discharge unit in which a purification filter is coupled to the high-pressure valve, and a low-pressure intake port upward of the operation chamber of the main body, It is composed of an air suction unit with a low-pressure opening / closing ball resiliently installed in a low-pressure intake mechanism.

따라서 본 발명의 저장탱크용 안전밸브는 이상압력이 발생시 고압밸브를 통해 내부공기를 배출하고 정화필터를 통하여 악취 등을 필터링하여 양질의 공기를 배출하도록 함과 동시에 펌핑작업 등으로 저압상태시 저압개폐볼이 열려 외부로 공기를 흡입하도록 하므로 원활하게 펌핑작업을 수행할 수 있을 뿐만 아니라 저장탱크의 내부압력을 항상 일정하게 유지시켜 안전하고 효율적으로 저장탱크를 관리할 수 있도록 하고 쾌적한 환경을 제공하는 효과가 있다.Therefore, the safety valve for the storage tank of the present invention discharges internal air through a high-pressure valve when an abnormal pressure occurs, filters odors, etc. through a purification filter, and discharges high-quality air, and also opens and closes at low pressure in a low-pressure state by pumping work. Since the ball is opened and sucks air to the outside, it is possible to perform a smooth pumping operation as well as to keep the internal pressure of the storage tank constant at all times to safely and efficiently manage the storage tank and provide a comfortable environment.

더욱이, 저압흡기구(132)의 중앙에는 가이드봉(133)으로 하향으로 돌출하도록 형성하고 가이드봉(133)의 하부에 저압개폐볼(135)을 상향으로 탄력 설치하므로 저압개폐볼(135)의 외주연이 저압흡기구(132)의 하단에 형성한 개폐단부(132b)에 밀착하도록 하되 계폐단부(132b)를 고무재질 등으로 형성하여 저압개폐볼(135)과의 밀착력을 향상시킬 수 있도록 한다.Moreover, the center of the low pressure intake mechanism 132 is formed so as to protrude downward with the guide rod 133, and the low pressure opening and closing ball 135 is elastically installed at the bottom of the guide rod 133. The peripheral edge is in close contact with the opening / closing end 132b formed at the lower end of the low-pressure intake mechanism 132, but the closed end 132b is formed of a rubber material or the like to improve adhesion with the low-pressure switch-ball 135.

여기서 가이드봉(133)의 하부에 저압개폐볼(135)을 관통시키고 저압개폐볼(135) 내부의 가이드봉(133)에 작동스프링(134)을 끼워 저압개폐볼(135)을 상향으로 탄력 설치하되, 저압개폐볼(135)의 상측에 슬라이드관(136)을 형성하여 상하로 원활하게 동작하도록 하고 가이드봉(133)의 하단에 걸림블록(133a)을 형성하여 작동스프링(134)의 하단을 지지하도록 함과 동시에 가이드봉(133)의 상단에 방사선상으로 지지리브(133b)를 형성하여 저압흡기구(132)와 일체화시키고 가이드봉(133) 상단에 지지스프링(137) 하단을 위치하여 저압흡기구(132)를 가압하도록 함이 이상적이다.Here, the low pressure switch ball 135 is penetrated to the lower portion of the guide bar 133, and the operating spring 134 is inserted into the guide bar 133 inside the low pressure switch ball 135, so that the low pressure switch ball 135 is elastically installed upward. However, the slide tube 136 is formed on the upper side of the low-pressure switch opening and closing ball 135 to operate smoothly up and down, and the locking block 133a is formed at the lower end of the guide rod 133 to form the lower end of the operating spring 134.

저장탱크 내부에 이상압력이 발생하면 작동실(111)에 연통시킨 고압밸브(123)에서 내부공기를 배출하여 항상 적정압력을 유지할 수 있도록 한다.When an abnormal pressure is generated inside the storage tank, internal air is discharged from the high-pressure valve 123 communicating with the operation chamber 111 to maintain the proper pressure at all times.

이때 배출한 내부공기는 정화필터(125)를 통하여 각종 이물질 및 악취를 필터링하여 양질의 공기를 배출하도록 하므로 쾌적한 환경를 제공할 수 있도록 한다.At this time, the discharged internal air filters various foreign substances and odors through the purification filter 125 to discharge high-quality air, thereby providing a comfortable environment.

더욱이, 펌프 운전 등에 따른 펌핑작업으로 내부에 저압상태가 발생하는 흡입력이 저압개폐볼(135)에 인가되고 이로 인하여 저압개폐볼(135)이 작동스프링(134)을 압축하면서 하강하여 외부로 공기를 흡입하므로 원활하게 펌핑작업을 수행할 수 있도록 하는 것이다.Moreover, by the pumping operation according to the pump operation, the suction force generated in the low pressure state is applied to the low pressure opening / closing ball 135, thereby causing the low pressure opening / closing ball 135 to descend while compressing the working spring 134 to discharge air to the outside. It is to make it possible to perform pumping work smoothly because it is inhaled.
