본 고안은 세이프티 밸브(safety valve)의 안전잠금장치에 관한 것으로서, 더욱 상세하게는 보일러나 에어컴프레셔(air compressor)에 사용되는 세이프티 밸브의 로크너트(lock nut)에 봉입캡을 씌우고 상기 봉인캡과 밸브 몸체끼리 서로 고정하게 하기 위해서 와이어와 같은 체결수단으로써 봉인하여 각 용기(보일러 또는 에어콤프레이셔)에 대한 세이프티 밸브의 설정압을 결정하는 어저스트 너트(adjust nut)를 함부로 조작하지 못하도록 하는 세이프티 밸브의 안전잠금장치에 관한 것이다.The present invention relates to a safety lock device of a safety valve, and more particularly, to enclose a sealing cap of a lock nut of a safety valve used in a boiler or an air compressor, To prevent valve bodies from being tampered with, adjust nuts that determine the set pressure of the safety valves for each vessel (boiler or air compressor) are sealed by means of fastening, such as wires, to hold the valve bodies together. A safety lock of the valve.

일반적으로, 세이프티 밸브는 증기를 발생시키는 보일러나 공기압을 이용하는 에어실린더나 물감을 캔버스에 분무토록 하는 핸드피스 (hand piece)등에 사용되는 에어컴프레셔에 장착되는데, 그 설치 목적은 상기 보일러나 에어컴프레셔 내부에 설정된 일정 허용압력이 초과 발생할 경우 초과 발생한 압력만 밖으로 배출시키게 하여 압축공기에 의한 폴발의 위험성을 제거하고자 하는데 있다.In general, the safety valve is mounted on an air compressor used for a steam generating boiler, an air cylinder using air pressure, or a hand piece for spraying paint onto a canvas, and the purpose of the installation is to install the inside of the boiler or air compressor. When the set allowable pressure is exceeded, the excess pressure is discharged out to remove the risk of polluting by compressed air.

좀더 구체적으로 종래의 세이프티 밸브의 내부 구조를 첨부도면 제1도에서 살펴보면, 일측만이 나사부(11)가 형성되고 상기 나사부(11) 내부에 소정 직경이 유입공(12)이 형성되고, 상기 유입공(12)과 접경하는 중앙내부에는 유입공(12) 보다 큰 직경을 갖고 타측단이 개방된 유로(13)가 형성되되, 상기 유로(13)는 외기와 관통되어 유입공(12)으로 부터의 설정압 이상의 공기를 배출하는 배기공(14), 내주면에 나사부(15)가 형성된 밸브몸체(16)와; 그 몸체와 나사결합하고 중앙 내부용기 일측단이 깔때기 형상의 볼지지편(17)이 형성된 릴리즈핀(18)을 유동결합한 어저서트너트(adjust nut, 19)와; 상기 어저스트너트(19)와 밸브몸체(16)의 풀림을 방지하기 위해 끼움결합되는 로크너트(20)와; 볼지지편(17)과 어저스트너트(19) 사이에 소정 탄성력을 갖는 코일스프링(21)을 개재하고, 유입공(12)과 유로(13)와 접경하는 단턱(22)과 볼지지편(17) 사이에 적어도 유입공(12)의 내경보다 큰 직경을 갖는 볼(23)을 항상 유입공(12)이 유로(13)와 차단되게 구비 위치하여 된 것인바, 이와같은 종래의 구조는 밸브몸체와 나사결합하여 설정된 어저스트너트의 수평위치를 고정하기 위한 로크너트가 누구나 쉽게 돌릴 수 있게 외기로 부터 개방되어 있어 어저스트너트의 변위에 따른 폭발의 위험성이 항상 도사리고 있었다.More specifically, when the internal structure of the conventional safety valve in Figure 1 attached to the drawing, only one side of the threaded portion 11 is formed and a predetermined diameter inlet hole 12 is formed inside the threaded portion 11, the inflow A central flow path 13 having a larger diameter than the inflow hole 12 and the other end is opened is formed in the center that borders the ball 12, and the flow path 13 penetrates the outside air and flows from the inflow hole 12. An exhaust hole 14 for discharging air above a set pressure of the valve body 16 having a threaded portion 15 formed on an inner circumferential surface thereof; An adjust nut (19) which is screwed to the body and fluidly coupled to the release pin (18) having a ball support piece (17) having a funnel shape at one end of the inner container; A lock nut 20 fitted to prevent loosening of the adjust nut 19 and the valve body 16; Between the ball support piece 17 and the adjust nut 19, the stepped portion 22 and the ball support piece which contact the inflow hole 12 and the flow path 13 through the coil spring 21 having a predetermined elastic force ( 17 is a ball 23 having a diameter larger than the inner diameter of at least the inlet hole 12 between the inlet hole 12 is always provided so as to be blocked from the flow path 13, such a conventional structure is a valve The lock nut for fixing the horizontal position of the adjust nut, which is set by screwing the body, is open from the outside so that anyone can easily turn, so there is always a risk of explosion due to the displacement of the adjust nut.

따라서, 본 고안은 상기와 같은 제반문제를 해결하기 위해 안출된 것으로서, 그 목적은 세이프티 밸브의 로크너트에 봉인캡을 씌우고 상기 봉인캡과 밸브몸체끼리 서로 고정하게 하기 위해 체결수단으로써 봉인하여 어저스트너트를 함부로 조작하지 못하도록 하는 세이프티 밸브의 안전잠금장치를 제공함에 있다.Therefore, the present invention has been made to solve the above problems, its purpose is to cover the lock nut of the safety valve and to seal with the fastening means to fix the sealing cap and the valve body to each other adjust The present invention provides a safety lock for a safety valve that prevents the nut from being tampered with.

상기 목적을 달성하기 위해 본 고안은 에어컴프레셔 등에 설치하여 공기압을 조절토록 하는 세이프티 밸브에 있어서, 상기 세이프티 밸브의 로크너트를 씌울수 있어 관통공과 체결공이 형성된 봉인캡을 구비하고, 상기 체결공과 수직되는 밸브몸체의 외벽 소정위치에 끼움공을 형성하고, 각각 체결공과 끼움공에 끼워 봉인캡의 이탈을 방지하게 하는 와이어를 구비하며, 상기 와이어에 끼워 봉인캡의 밀착력을 높여주는 회전체결구를 구성하여 된 특징을 갖는다.In order to achieve the above object, the present invention has a safety valve installed in an air compressor or the like to control the air pressure, and includes a seal cap formed with a through hole and a fastening hole to cover the lock nut of the safety valve, and is perpendicular to the fastening hole. Forming a fitting hole in a predetermined position on the outer wall of the valve body, and provided with a wire to prevent the detachment of the sealing cap by inserting into the fastening hole and the fitting hole, respectively, and constitutes a rotary fastener to increase the adhesion of the sealing cap to the wire Has features.

이하, 본 고안은 첨부한 도면에 의거하여 보다 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제2도는 본 고안이 분리 사시도이고, 제3도는 본 고안의 결합상태 부분단면도로서, 에어컴프레셔등이 설치하여 공기압을 조절토록 하는 세이프티 밸브에 있어서, 상기 세이프티 밸브10)의 로크너트(20)를 씌울 수 있게 봉인캡(30)을 구비한다.FIG. 2 is an exploded perspective view of the present invention, and FIG. 3 is a partial cross-sectional view of the combined state of the present invention. In the safety valve for installing an air compressor or the like to adjust the air pressure, the lock nut 20 of the safety valve 10 is removed. It is provided with a sealing cap 30 to be covered.

상기 봉인캡(30)의 상면 중앙에는 어저스트너트(19)를 관통할 수 있는 관통공(31)이 형성되고, 상면 가장자리에 체결공(32)이 형성되어 있다. 또한, 상기 봉인캡(30)의 체결공(32)과 일직선상의 밸브몸체(16)의 외벽 소정위치에 체결공(32)과 같은 직경의 끼움공(33)을 형성한다.In the center of the upper surface of the sealing cap 30, a through hole 31 through which the adjust nut 19 is formed, and a fastening hole 32 is formed at the edge of the upper surface. In addition, the fitting hole 33 having the same diameter as the fastening hole 32 is formed at a predetermined position of the outer wall of the valve body 16 in a straight line with the fastening hole 32 of the sealing cap 30.

한편, 상기 체결공(32)과 끼움공(33)에 한 가닥의 와이어(34) 끝단과 타단을 각각의 구멍에 끼워 봉인캡(30)의 이탈을 방지하도록 하되, 그 전에 먼저 와이어(34)를 좌우 외벽에 서로 대칭 관통된 구멍내에 끼우게 하는 회전체결구(35)를 구비힌다. 상기 회전체결구(35)는 그 자체를 손으로 돌려 와이어(34)의 꼬임으로 인한 체결력을 증가시키도록 하기 위한 것이다.Meanwhile, one end of the wire 34 and the other end of the strand 34 are inserted into the respective holes to prevent the sealing cap 30 from being separated from the fastening hole 32 and the fitting hole 33. Rotating fasteners 35 are provided on the left and right outer walls so as to fit in the holes symmetrically penetrated to each other. The rotary fastener 35 is intended to increase the fastening force due to the twisting of the wire 34 by hand by itself.

상기와 같이 구성된 본 고안의 작용 효과를 설명한다.It describes the effect of the present invention configured as described above.

먼저, 봉인캡(30)의 관통공(31)이 어저스트너트(19)로 관통되게 상기 봉인캡(30)을 씌운뒤 체결공(32)이 밸브몸체(16)의 끼움공(33)과 일직선이 되게조절한다.First, the sealing cap 30 is covered with the sealing cap 30 so that the through hole 31 of the sealing cap 30 passes through the adjust nut 19, and then the fastening hole 32 is fitted with the fitting hole 33 of the valve body 16. Adjust in a straight line.

한편, 와이어(34) 회전체결구(35) 각각의 구멍으로 일단과 타단을 끼우고 다시 와이어(34)의 각 단을 각각 봉인캡(30)의 체결공(32)과 밸브몸체(16)의 끼움공(33)으로 끼워 와이어(34) 각 끝단을 서로 꼰다. 이상태에서는 봉인캡(3)이 헐거운 상태이므로 회전체결구(35)를 와이어(34)가 꼬이는 방향으로 돌려 밀착력을 증가시켜 준다.On the other hand, the one end and the other end of the wire 34, each of the rotary fastener 35 is inserted into the end of each of the fastening hole 32 and the valve body 16 of the sealing cap 30 again The end of the wire 34 is braided with each other by fitting holes 33. In this state, since the sealing cap 3 is loose, the rotary fastener 35 is turned in the twisting direction of the wire 34 to increase the adhesion.

따라서, 이와 같은 본 고안을 실제로 적용하게 되면, 실수 또는 고의로 오조작되는 어저서트너트의 위치 상태를 봉인캡으로써 보존하게 되고 특히, 고의로 억지 조작을 할려면 와이어를 절단해야 하므로 그 상태가 파악되어 관계자로 하여금 용이하게 대처할 수 있는 유용한 고안인 것이다.Therefore, if the present invention is actually applied, the position state of the mistaken or deliberately misoperated adjuster nut is preserved by the sealing cap, and in particular, the state is grasped because the wire must be cut in order to intentionally operate it. It is a useful design that can easily cope with.
