Description

안전밸브의 안전잠금장치.Safety lock of safety valve.

본 고안은 안전밸브(safety valve)의 안전잠금장치에 관한 것으로서, 구체적으로 보일러나 에어컴프레셔에 사용되는 안전밸브의 밸브본체 상단과 조절너트의 하단 일측에 나사구멍을 형성한 뒤 이 나사구멍에 조절공을 가진 안전잠금구를 체결토록 함으로써 각 용기(보일러 또는 에어컴프레셔)에 대한 안전밸브의 설정압을 결정하는 조절너트(adjust nut)를 함부로 조작하지 못하도록 한 것에 관한 것이다.The present invention relates to a safety lock device for a safety valve, and specifically, a screw hole is formed at the upper end of the valve body and a lower end of the adjustment nut of a safety valve used in a boiler or an air compressor, and then adjusted in the screw hole. By engaging a safety lock with a ball, it is possible to avoid tampering with an adjust nut that determines the set pressure of the safety valve for each vessel (boiler or air compressor).

일반적으로, 안전밸브는 증기를 발생시키는 보일러나 에어컴프레셔에 장착되는데, 그 설치목적은 보일러나 에어컴프레셔 내부에 미리 설정된 허용압력이 초과발생할 경우에 초과 발생한 압력만 밖으로 배출시키게 하여 압축공기에 의한 폭발의 위험성을 제거하고자 하는데 있다.In general, the safety valve is installed in a boiler or an air compressor that generates steam, and the purpose of installation is to discharge only the excess pressure when the preset allowable pressure inside the boiler or air compressor is exceeded, thereby causing an explosion by compressed air. To eliminate the risk of

그런데 이러한 폭발위험성을 제거하기 위해 설치되는 종래의 안전밸브는 조절너트의 수평위치를 고정하기 위한 록너트가 누구나 쉽게 돌릴수 있게 외기로부터 개방되어 있어 조절너트의 변위에 따른 또다른 폭발의 위험성이 있다는 것이고, 따라서 상기한 안전밸브의 폭발위험성을 제거하기 위한 방안이 여럿 있으나 그 가운데서도 실용신안출원제 95-9832호의 경우를 도 3a 및 도 3b를 통해 살펴보면, 보일러나 에어컴프레셔등에 설치하여 공기압을 조절토록 하는 안전밸브(1')에 있어서,However, the conventional safety valve that is installed to remove the explosion risk is that the lock nut for fixing the horizontal position of the adjustment nut is open from the outside air so that anyone can easily turn, there is another risk of explosion due to displacement of the adjustment nut Therefore, there are several methods for eliminating the explosion risk of the safety valve, but among them, the case of Utility Model Application No. 95-9832 is shown in FIGS. 3A and 3B to install the boiler or air compressor to adjust the air pressure. In the safety valve (1 ')

안전밸브(1')의 록너트(Rock nut : 10)를 덧씌울 수 있게 관통공(11)과 체결공(12)이 형성된 봉인캡(13)을 구비하고, 체결공(12)과 수직되는 밸브본체(2') 외벽의 소정위치에 끼움공(14)을 형성하며, 아울러 체결공(12)과 끼움공(14)에 와이어(15)를 끼워 봉인캡(13)의 밀착력을 높여주는 회전체결구(16)를 구성한 것으로 되어 있는바, 이와 같은 장치구조의 문제점은 무엇보다도 와이어(15)가 떨어져 나가버리면 안전잠금장치로서의 기능을 발휘할 수 없는데다가 봉인캡(13) 또한 통상의 육각너트를 그냥 그대로 사용할 수 없는 구조로 되어 있기에 별도의 봉인캡(13)을 제조한 뒤 봉인캡(13)의 일측에 체결공(12)을 형성한 상태에서 통상의 육각너트로 되어 있는 록너트(10)를 상기 봉인캡(13) 내부에 강제박음하되, 체결공(12)이 육각너트의 접점지역을 벗어난 공간부사이에 위치되도륵 함과 동시에 체결공(12)이 밸브본체(2') 외벽의 끼움공(14)과 수직되도록 형성해야 하는 관계로 제조하기가 여간 까다롭지 아니하며 이밖에 별도의 회전체결구(16)마저 형성한 상태에서 일측의 와이어(15)를 회전체결구(16)의 구멍(17)사이로 끼워 넣은 뒤 체결공(12)과 매우 좁은 틈새로 가진 공간부 사이로 와이어(15)를 빼내고 반면에 타측의 와이어(15)는 회전체결구(16)의 또다른 구멍(17')으로 끼워 끼움공(14)으로 빼낸 뒤 상기 체결공(12) 및 공간부 사이로 빠져 나온 와이어(15)와 함께 꼬아서 체결토록 한 구조로 되어 있기에 제조는 물론 체결 방법마저 번거롭기 그지없으며 더군다나 와이어(15)에 의한 안전잠금장치가 체결되어 있다손 치더라도 운반 및 사용과정에서 회전체결구(16)의 걸림등에 의해 와이어(15)가 종종 떨어져 나가는 등, 이로인한 폐단이 매우 심각한 문제가 있었던 것이다.It is provided with a sealing cap 13 formed with a through hole 11 and a fastening hole 12 to cover the lock nut 10 of the safety valve 1 ', and is perpendicular to the fastening hole 12. The fitting hole 14 is formed at a predetermined position of the outer wall of the valve body 2 'and the wire 15 is inserted into the fastening hole 12 and the fitting hole 14 to increase the adhesion of the sealing cap 13. Since the entire fastener 16 is constituted, the problem of the device structure is that, above all, if the wire 15 falls off, the function as a safety locking device cannot be exerted, and the sealing cap 13 also has a normal hexagonal nut. Lock nut 10 made of a regular hexagon nut in a state in which a fastening hole 12 is formed on one side of the sealing cap 13 after manufacturing a separate sealing cap 13 because the structure is not just usable. Is pushed into the sealing cap 13, the fastening hole 12 is located between the space portion out of the contact area of the hexagon nut At the same time, since the fastening hole 12 should be formed perpendicular to the fitting hole 14 of the outer wall of the valve body 2 ', it is not difficult to manufacture it. In the formed state, the wire 15 on one side is inserted between the holes 17 of the rotary fastener 16, and the wire 15 is pulled out between the fastening hole 12 and the space portion having a very narrow gap, while the other side The wire 15 is inserted into another hole 17 ′ of the rotation fastener 16 and pulled out by the fitting hole 14, and then twisted together with the wire 15 that is pulled out between the fastening hole 12 and the space part. Because of its structure, the manufacturing method as well as the fastening method are not only a hassle. Furthermore, the safety locking device by the wire 15 is fastened by the hooks of the rotating fasteners 16 in the process of transportation and use even if damaged. Lungs often fall off) This would have been a very serious problem.

본 고안은 상기와 같은 문제를 해결하기 위해 안출된 것으로서,The present invention has been devised to solve the above problems,

그 목적은 안전밸브의 밸브본체 상단에 나사구멍을 내고 조절너트 하단일측에도 또 다른 나사구멍을 형성한 후 조절공을 가진 안전잠금구를 상기 나사구멍에 체결토록 함으로써 조절너트를 함부로 조작하지 못하도록 하는 안전밸브의 안전잠금장치를 제공함에 있다.The purpose of this is to make a screw hole on the top of the valve body of the safety valve and to form another screw hole on one side of the lower end of the adjustment nut, and then to fasten the safety lock with the adjustment hole to the screw hole to prevent the operation of the control nut. It is to provide a safety lock of the safety valve.

상기 목적을 달성하기 위해 본 고안은 보일러나 에어컴프레셔 등지에 설치하여 공기압을 밸브본체 상단과 조절너트의 하단일측에 나사구멍을 각각 형성한 뒤 이 나사구멍에 조절공을 가진 안전잠금구를 체결토록 한 특징을 갖는데 이하, 첨부된 도면에 의거하여 보다 상세하게 설명하여 보면 다음과 같다.In order to achieve the above object, the present invention is installed in a boiler or an air compressor, and the air pressure is formed at the upper end of the valve body and the lower end of the adjusting nut, respectively, and then the safety lock with the adjusting hole is fastened to the screw hole. Having a feature, hereinafter will be described in more detail based on the accompanying drawings.

도면에서 보듯이 안전밸브(1)를 형성함에 있어서,As shown in the figure, in forming the safety valve 1,

밸브본체(2)의 상단 일측지점에 나사산을 가진 나사구멍(4)을 형성하고 조절너트(3)의 하단일측지점에도 나사산을 가진, 또 다른 나사구멍(5)을 형성한다.A threaded screw hole 4 is formed at one upper end of the valve body 2 and another threaded hole 5 is formed at one lower end of the adjusting nut 3.

그리고 조절공(6)을 가진 별단의 안전잠금구(7)를 상기 밸브본체(2)의 나사구멍(4) 및 조절너트(3)의 나사구멍(5)에 체결토록 함으로써 안전잠금구(7)를 풀지 않는 한 조절너트(3)가 전혀 조작될 수 없도록 구성한다.Then, the safety lock 7 of the other end having the adjustment hole 6 is fastened to the screw hole 4 of the valve body 2 and the screw hole 5 of the adjustment nut 3 to secure the safety lock 7. It is configured so that the adjusting nut (3) can not be operated at all unless the) is released.

미 설명부호 8은 릴리즈핀이고 9는 배기공이다.Reference numeral 8 is a release pin and 9 is an exhaust hole.

상기와 같이 구성된 본 고안의 작용·효과를 설명한다.The operation and effects of the present invention configured as described above will be described.

먼저, 밸브본체(2)에 조절너트(3)를 체결시키되, 밸브본체(2)의 나사구멍(4)과 조절너트(3)의 나사구멍(5)이 일치되도록 형성한다.First, the adjustment nut 3 is fastened to the valve body 2, and the screw hole 4 of the valve body 2 and the screw hole 5 of the adjustment nut 3 are formed to coincide.

즉 조절너트(3)의 나사구멍(5)이 밸브본체(2)의 나사구멍(4)과 일치될 경우에는 보일러나 에어 컴프레이셔 내부에 설정된 허용 압력이 정상상태라는 것이고 따라서 나나구멍(4)(5)이 일치 되었을 경우에 안전잠금구(7)의 조절공(6)에 아무 철심대(미도시됨)나 넣고 돌리되, 안전잠금구(7)의 끝단이 조절너트(3)의 나사구멍(5) 내부 끝에 닿을 때까지 단단히 체결토록 한다.In other words, when the screw hole 5 of the adjusting nut 3 coincides with the screw hole 4 of the valve body 2, the allowable pressure set inside the boiler or the air compressor is in a normal state, and thus the screw hole 4 If (5) is matched, insert any iron core (not shown) into the adjusting hole (6) of the safety lock (7), and turn, but the end of the safety lock (7) of the adjustment nut (3) Tighten it firmly until it reaches the inner end of the screw hole (5).

이상에서 설명한 바와 같이 본 고안을 안전밸브(1)에 실제 적용하게 된다면,조절너트(3)의 위치상태가 온전하게 될뿐아니라 고의로 조절너트(3)를 억지 조작하려면 1차적으로 단단히 체결되어 있는 안전잠금구(7)를 풀어내어야 하는 만큼 실수나 오조작에 의한 조절너트(3)의 풀림 가능성은 거의 없다 할 것이고(고의 조작만은 어떤 경우이든간에 막을 재간이 없다 할 것임) 따라서 매우 간단한 구조로서 안전밸브(1)의 안전장치를 효과적으로 이룩해낼 수 있는 유용한 고안이라 할 것이며 나아가 현실적용가능성이 매우 큰 실용적인 개발품이라 할 것이다.As described above, if the present invention is actually applied to the safety valve 1, the position of the adjustment nut 3 is not only intact, but also the first purpose is to firmly tighten the control nut 3 to forcibly operate the adjustment nut 3. As long as the safety lock (7) must be released, there is little possibility of loosening of the adjusting nut (3) by mistake or misoperation (intentional operation will not stop in any case). As a structure, it will be said to be a useful design that can effectively achieve the safety device of the safety valve 1, and furthermore, it will be said to be a practical development product with great practical applicability.
