The pressure discharge hole is formed to open upward from the center of the fluid discharge pipe made of stainless steel, and the opening and closing disc is mounted so as to be vertically elevated above the pressure discharge hole, and the annular contact portion formed on the bottom of the opening and closing disc faces the pressure discharge hole. The pressure discharge hole is opened and closed to open and close the pressure discharge hole when the pressure is released.The pressure is quickly released and the pressure is released. And knocking phenomenon when the disc is lifted It prevents the steam discharged through the pressure discharge hole from easily flowing into the support tube supporting the opening / closing disc, and the water condensed in the support tube is quickly discharged to the lower part of the support tube so that freezing phenomenon does not occur in the support tube during the winter season. will be.

종래의 압력용기 안전밸브는 밸브본체를 구성하는 유체배출관에 유체배출공을 형성하고 그 외측에 유체배출방향과 반대 방향으로 소정압력이 작용하도록 개폐구를 장치하여 개폐면에 별도의 패킹을 장치하기 때문에 패킹장치와 관련한 설비가 개폐구의 일부가 개폐구 중심에 장치되어 유체배출공의 유체통로 속으로 투입되므로 유체통로 일부를 잠식하게 되어 유체배출공이 좁아지기 때문에 개폐구가 열려도 유체 배출이 원활하게 달성되지 않아 압력해소가 느려지는 불편이 있고, 접촉면에 장치된 패킹이 지나치게 압착되지 않도록 접촉거리를 제한하는 조정링을 개폐부 외면에 장치해야 하므로 조립이 복잡하고 유지관리가 어려워 사용이 불편한 결점이 있었다.In the conventional pressure vessel safety valve, since a fluid discharge hole is formed in the fluid discharge pipe constituting the valve body, an opening and closing device is provided on the outer side so that a predetermined pressure is applied in a direction opposite to the fluid discharge direction. Since some of the equipment related to the packing device is installed in the center of the opening and closing part of the opening and closing, the fluid outlet hole is narrowed by enclosing part of the fluid passage and the fluid discharge hole is narrowed. There is a disadvantage in that the pressure relief is slow, and an adjustment ring for limiting the contact distance must be installed on the outer surface of the opening and closing part so that the packing installed on the contact surface is not excessively squeezed.

본 고안은 위와 같은 종래의 결점을 해소시키기 위하여 개발한 것이다.The present invention has been developed to solve the above conventional drawbacks.

본 고안은 스테인레스스틸제로 된 안전밸브의 밸브본체를 구성하는 유체배출관에 압력배출공을 형성하고 상측에 배출방향과 반대 방향으로 소정 압력이 작용하도록 코일스프링에 장치된 스테인레스스틸제로 제조된 개폐디스크를 장치하되 개폐디스크와 압력배출공이 접촉하는 접촉면 중심부에 장애물이 없도록 만들어서 압력배출시 배출장애가 없도록 개폐장치를 구성하고 이로인해 설정압 이상이 되어 유체 배출공이 개방될 때 완전한 개방이 이루어져 신속한 압력해소가 달성되며 개폐디스크가 닫힐 때 밀착이 완벽하여 정밀성이 담보될 수 있고, 승강작용시 녹킹현상이 없으며 개폐디스크를 지지하는 지지관속으로 배출스팀이 유입되는 것을 막아 겨울철 액화된 스팀의 수분으로 지지관이 동파되는 것을 방지할 수 있는 안전밸브가 되도록 만든 것이다.The present invention provides an opening and closing disk made of stainless steel mounted on the coil spring to form a pressure discharge hole in the fluid discharge pipe constituting the valve body of the safety valve made of stainless steel and to act a predetermined pressure in the opposite direction to the discharge direction on the upper side. A switchgear is constructed so that there is no obstacle in the center of the contact surface where the opening and closing disk and the pressure discharge hole are in contact with each other. When the disc closes, the close contact is perfectly secured to ensure accuracy, and there is no knocking phenomenon when lifting and lowering, and the discharge pipe is prevented from flowing into the support pipe supporting the disc. Designed to be a safety valve to prevent will be.

이와 같이 된 본 고안은 스테인레스스틸제로 제조된 개폐디스크(3)가 유체배출관(1)의 압력배출공(1a) 수직상부에 장치되어 압력배출공(1a) 상단 접촉부(1b)에 개폐디스크(3)의 하단부 환상접촉부(3b)가 밀착하여 면접촉이 이루어지도록 코일스프링(6)의 압력을 받으면서 유지되도록 되어 있어 압력배출공(1a)의 밀봉작용이 완벽하고 유체배출관(1)속에 설정압력 이상의 압력이 축적되어 개폐디스크를 밀어올릴 경우 코일스프링(6)이 압력을 견디지 못해 수축되면서 개폐디스크(3)가 상승하면 압력배출공(1a) 둘레가 완전히 개방되고 압력배출공(1a) 중심부에 배출 장애요소가 없기 때문에 압력배출공을 통해 내부에 충진된 유체압력이 일시에 해소되는 효과가 있어 압력해소가 신속하게 이루어져 위험을 빨리 해소하게 되는 이점이 있고, 압력이 해소되어 설정압력 이하가 되면 코일스프링의 복원력에 의하여 개폐디스크가 하향하므로 개폐디스크의 환상접촉부(3b)가 압력배출공(1a) 상단 접촉부(1b)에 밀착하여 면접촉을 달성하므로 압력배출공(1a)이 닫히는 작동이 이루어진다.In this invention, the opening and closing disk (3) made of stainless steel is installed in the vertical portion of the pressure discharge hole (1a) of the fluid discharge pipe (1), the opening and closing disc (3) in the upper contact portion (1b) of the pressure discharge hole (1a). The lower end of the annular contact portion (3b) is in close contact with the pressure of the coil spring (6) to maintain the surface contact, so that the sealing action of the pressure discharge hole (1a) is perfect and the set pressure in the fluid discharge pipe (1) When pressure accumulates and pushes the open / close disk, if the coil spring (6) does not withstand the pressure and contracts and the open / close disk (3) rises, the periphery of the pressure discharge hole (1a) is completely opened and discharged to the center of the pressure discharge hole (1a). Since there is no obstacle, there is an effect that the pressure of the fluid filled inside through the pressure discharge hole is temporarily eliminated. Therefore, the pressure can be quickly eliminated and the risk can be quickly eliminated. When the pressure is less than the force, the opening and closing disk is lowered by the restoring force of the coil spring, so that the annular contact portion 3b of the opening and closing disk closely contacts the upper contact portion 1b of the pressure discharge hole 1a, thereby achieving surface contact. The closing operation is made.

또한, 본 고안은 개폐디스크(3)의 상단부 외주에 수직안내부(3a)가 형성되어 지지관(2)의 수직안내관(2c)에 하단 개방부로 삽입되어 상하로 슬라이드 되고 개폐디스크의 수직안내부(3a) 외면에 일정간격으로 세로홈(3a')이 형성되어 있으므로 상하로 슬라이드 될 때 접촉면에서의 마찰을 저하시켜서 녹킹을 방지하고 스팀 보일러의 경우 수직안내관(2c) 내부로 스팀이 스며들어 수분이 발생할 경우 수분을 외부로 배출시키므로 동절에 지지관(2)이 동파되는 사고를 방지하는 이점이 있다.
그리고 본 고안의 개폐디스크는 환상접촉부(3b) 외주 상방에 수직안내부(3a) 외경보다 외경이 확장되는 환상돌출부(3c)가 형성되어 있어서 압력배출공 개방시에 배출되는 스팀이 지지관(2)의 수직안내관(2c)속으로 쉽게 유입되는 것을 저지하므로 코일스프링(6)이 스팀열기를 받아 강도가 변화하는 것을 예방하게 되는 이점도 얻게 되며In addition, the present invention is a vertical guide portion (3a) is formed on the outer periphery of the upper end of the opening and closing disc (3) is inserted into the lower opening in the vertical guide tube (2c) of the support tube (2) slides up and down and vertical guide of the opening and closing disc Since the vertical grooves 3a 'are formed on the outer surface of the part 3a at regular intervals, it prevents knocking by lowering friction at the contact surface when sliding up and down, and in the case of the steam boiler, steam leaks into the vertical guide pipe 2c. For example, when water is generated, the water is discharged to the outside, and thus there is an advantage of preventing accidents in which the support pipe 2 freezes in winter.
In addition, the opening and closing disk of the present invention has an annular protrusion (3c) is formed on the outer circumference of the annular contact portion (3b) to extend the outer diameter than the outer diameter of the vertical guide portion (3a) support steam (2) Since it is easy to prevent the flow into the vertical guide tube (2c) of the) also has the advantage that the coil spring (6) receives steam heat to prevent the strength change

압력조절 나사관(4)의 위치를 상하로 조정하여 코일스프링(6)의 탄력강도를 조정할 수 있어서 안전밸브의 개방점을 변경할 수 있으므로 스팀 설정 압력의 변경에 대응할 수 있는 이점이 있다. Since the elastic strength of the coil spring 6 can be adjusted by adjusting the position of the pressure regulating screw pipe 4 up and down, the opening point of the safety valve can be changed, and thus there is an advantage in that it can cope with a change in the steam set pressure.

본 고안은 스테인레스스틸제로 되어 중심부에 수직방향으로 압력배출공(1a)이 형성되어 상단이 환상의 평면 접촉부(1b)로 형성되는 유체배출관(1)과 스테인레스스틸제로 되어 유체배출관(1)의 압력배출공 외주벽에 형성된 수나사부(1c)에 하측 결합나사부(2a)가 나사조립되어 결합되고 결합나사부(2a) 주벽에서 외측방향으로 배출부(2b)가 형성되며 중심부에 유체배출관의 압력배출공(1a)과 수직선상에 위치하고 하단이 개방되게 수직안내관(2c)이 형성되어 수직안내관 입구와 압력배출공(1a)사이에 개폐공간이 형성되는 지지관(2)과 스테인레스스틸제로 되어 압력배출관의 압력배출공(1a)과 압력배출공 직상부로 형성된 지지관의 수직안내관(2c)사이에 형성된 개폐공간에 장착되고 수직안내관 속으로 출입되는 수직안내부(3a)가 상부측에 형성되고 수직안내부 상단 중심부에 V형홈(3d)이 형성되며 하단부에 압력배출공(1a)의 환상 접촉부(1b)에 접촉하는 환상접촉부(3b)가 형성된 개폐디스크(3)와 스테인레스스틸제로 되어 지지관(2)의 상단 나사관(2d)의 중심 암나사공에 나사조립되는 압력조절나사관(4)과 압력조절나사관(4)의 중심안내공(4a)에 끼워 저 하단지지부(5a)가 개폐용 디스크(3)의 V형홈(3d)에 끼워져 수직으로 유지되는 연결봉(5)과 압력조절나사관의 하단부(4b)와 연결봉(5)의 하단지지부(5a) 사이에 개입되며 스테인레스스틸제로 제작되고 상하측에 스프링받침(6a)(6b)이 끼워진 코일스프링(6)과 압력조절나사관(4)의 수나사부(4c)에 나사조립되는 고정너트(7)와 지지관(2)의 상단나사관(2d) 수나사부에 나사조립되는 캡너트(8)로 구성된 보일러 압력용기용 안전밸브에 있어서,
