The first pressure reducing unit 300 primarily reduces the pressure of the fluid flowing through the inlet 110 while being built into the valve body 100 and guides it to the valve seat 130, The inner tube body 310 formed on the side of the inner through hole 311 connected in communication with the upper part through which the fluid passes, and the inner tube body 310 is coupled in a state of wrapping, corresponding to the inner through hole 311 so that the fluid It includes an outer tube body 320 through which an outer through hole 321 is formed on the side.

내부관통홀(311) 및 외부관통홀(321)은 각각 다수로 구성되면서 서로 마주되지 않게 어긋나는 위치에 형성된다. The inner through-hole 311 and the outer through-hole 321 are each configured in plurality and formed at positions that are offset from each other so as not to face each other.

그리고, 내부관체(310)는 내부관통홀(311)들의 상부 및 하부에 지지턱(312)이 형성된다. 따라서, 외부관체(320)가 내부관체(310)에 결합되어 외부관체(320)의 내주면이 지지턱(312)에 지지되면 내부관통홀(311)들과 외부관통홀(321)들의 사이에 공간이 형성된다. And, the inner tube body 310 has support projections 312 formed on the upper and lower portions of the inner through-holes 311 . Therefore, when the outer tube body 320 is coupled to the inner tube body 310 and the inner circumferential surface of the outer tube body 320 is supported by the support jaw 312, there is a space between the inner through-holes 311 and the outer through-holes 321. is formed

이러한 상태에서, 외부관통홀(321)들을 유체가 분산되어서 통과하므로 유체의 압력이 저감된다. 외부관통홀(321)을 통과하면서 압력이 저감된 유체가 내부관통홀(311)을 통해 즉시 통과되지 못하고, 내부관통홀(311)들과 외부관통홀(321)들의 사이에 형성된 공간으로 유입된다. 그리고, 공간으로 유입된 유체가 외부관통홀(321)들에 분산되어서 통과하므로 유체의 압력이 추가로 저감된다. In this state, since the fluid passes through the external through-holes 321 in a dispersed manner, the pressure of the fluid is reduced. The fluid whose pressure is reduced while passing through the external through-hole 321 does not immediately pass through the internal through-hole 311, but flows into the space formed between the internal through-holes 311 and the external through-holes 321. . In addition, since the fluid introduced into the space is dispersed and passed through the external through-holes 321, the pressure of the fluid is further reduced.

제2감압부(400)는 밸브시트(130)에 설치된 상태로 제1감압부(300)를 관통한 유체의 압력을 2차로 감압시켜서 배출구(120)로 안내하는 것으로, 밸브시트(130)의 걸림턱(131)에 걸려서 고정되고, 밸브시트(130)로 유입되는 유체가 분산되어서 관통되는 다수의 감압홀(411)이 형성되는 감압판(410)과, 밸브시트(130)의 암나사산(132)에 나사결합 되고, 감압판(410)을 관통한 유체가 분산되어서 관통되는 다수의 감압홀(421)이 형성되는 마감감압판(420)과, 감압판(410) 및 마감감압판(420)의 사이에 위치되어 감압판(410) 및 마감감압판(420)의 이격된 상태를 유지시키는 간격유지부(430)를 포함한다. The second decompression unit 400 secondarily reduces the pressure of the fluid passing through the first decompression unit 300 in a state installed on the valve seat 130 and guides it to the outlet 120, the valve seat 130 A pressure-reducing plate 410 that is caught and fixed on the locking jaw 131 and has a plurality of pressure-reducing holes 411 formed through which the fluid flowing into the valve seat 130 is dispersed and penetrated, and a female thread of the valve seat 130 ( 132), the pressure reducing plate 420 having a plurality of pressure reducing holes 421 through which the fluid passing through the pressure reducing plate 410 is dispersed, and the pressure reducing plate 410 and the pressure reducing plate 420 finishing. ) It includes a spacer 430 positioned between the pressure reducing plate 410 and the closing pressure plate 420 to maintain a spaced state.

그리고, 제2감압부(400)의 감압판(410), 마감감압판(420), 간격유지부(430)에는 진동방지부(230)가 관통되어서 승강되는 승강감압홀(401)이 형성된다. 이러한, 승강감압홀(401)들은 서로 연통된다. 따라서, 진동방지부(230)인 핀이 승강감압홀(401)들에 관통된 상태에서 승강될 수 있다. In addition, the pressure reducing plate 410, the closing pressure plate 420, and the gap maintaining part 430 of the second pressure reducing unit 400 are formed with a lifting and reducing pressure hole 401 through which the anti-vibration part 230 penetrates and moves up and down. . These elevation/decompression holes 401 communicate with each other. Accordingly, the pins of the anti-vibration unit 230 can be moved up and down while passing through the up and down decompression holes 401 .

여기서, 진동방지부(230)인 핀이 제2감압부(400)에 관통된 상태로 승강되므로, 플러그(210)가 상승되어서 밸브시트(130)를 개방하면 유체가 고압으로 관류됨에 따라 밸브시트(130)에서 진동이 발생될 수 있다. 이때, 진동방지부(230)인 핀이 제2감압부(400)의 승강감압홀(401)에 관통되어서 지지된 상태이므로, 진동발생이 방지되어 밸브시트(130) 및 플러그(210)의 파손됨이 예방될 수 있다. 또한, 진동발생에 의한 소음발생도 방지될 수 있다. Here, since the pin, which is the anti-vibration part 230, is moved up and down while passing through the second pressure reducing part 400, when the plug 210 is lifted to open the valve seat 130, the fluid flows through the valve seat at high pressure. Vibration may be generated at 130. At this time, since the pin, which is the anti-vibration part 230, passes through the lifting/decreasing pressure hole 401 of the second pressure reducing part 400 and is supported, the occurrence of vibration is prevented and the valve seat 130 and the plug 210 are damaged. becoming can be prevented. In addition, the generation of noise due to the generation of vibration can be prevented.

감압판(410)에 감압홀(411)들이 분산되어서 형성되어 유체가 분산되어서 통과하는 과정에서 유체의 압력이 감압될 수 있다. Pressure-relief holes 411 are dispersed in the pressure-relief plate 410, and the pressure of the fluid can be reduced while the fluid is dispersed and passed through.

이러한, 감압판(410)은 복수로 구성되어 상하로 적층되어서 사용될 수 있다. 이때, 감압판(410)들에 형성되는 감압홀(411)들은 서로 마주되지 않도록 서로 어긋나는 위치에 형성된다. 더욱이, 하부에 위치하는 감압판(410)의 감압홀(411)들은 상부에 위치하는 감압판(410)의 감압홀(411)들보다 작은 수로 형성될 수 있다. 따라서, 상부에 위치하는 감압판(410)의 감압홀(411)들을 통과하면서 감압된 유체가 하부에 위치하는 감압판(410)의 감압홀(411)들을 즉시 통과하지 못하고, 하부의 감압판(410)의 상부면에 충돌되면서 다시 감압된 후에 하부의 감압판(410)에 분산되게 형성된 감압홀(411)들을 통과하면서 또다시 감압될 수 있다. These pressure-reducing plates 410 may be composed of a plurality and stacked vertically. At this time, the pressure-relief holes 411 formed in the pressure-relief plates 410 are formed at positions offset from each other so as not to face each other. Furthermore, the number of pressure-reducing holes 411 of the pressure-reducing plate 410 positioned at the bottom may be smaller than the number of pressure-reducing holes 411 of the pressure-reducing plate 410 positioned at the top. Therefore, the pressure-reduced fluid passing through the pressure-reducing holes 411 of the pressure-reducing plate 410 located at the top does not immediately pass through the pressure-reducing holes 411 of the pressure-reducing plate 410 located at the bottom, and the lower pressure-reducing plate ( 410), the pressure is reduced again, and then the pressure can be reduced again while passing through the pressure reduction holes 411 formed to be dispersed in the lower pressure plate 410.

마감감압판(420)에도 감압홀(421)들이 분산되어서 형성되어 감압판(410)을 관통한 유체가 분산되어서 감압홀(421)들을 통과하는 과정에서 유체의 압력이 다시 감압될 수 있다. 여기서, 마감감압판(420)의 감압홀(421)들은 감압판(410)의 감압홀(411)들보다 작은 수로 형성될 수 있다. Pressure-reducing holes 421 are also distributed in the pressure-reducing plate 420 so that the fluid passing through the pressure-reducing plate 410 is dispersed and the pressure of the fluid can be reduced again in the process of passing through the pressure-reducing holes 421 . Here, the pressure reducing holes 421 of the pressure reducing plate 420 may be formed in a smaller number than the pressure reducing holes 411 of the pressure reducing plate 410 .

그리고, 마감감압판(420)은 외주면에 수나사산이 형성되어 밸브시트(130)의 암나사산(132)에 나사결합 된다. 또한, 마감감압판(420)은 밸브시트(130)에 용접으로 결합될 수도 있다. And, the closing pressure plate 420 has a male thread formed on the outer circumferential surface and is screwed to the female thread 132 of the valve seat 130. In addition, the closing pressure plate 420 may be coupled to the valve seat 130 by welding.

여기서, 제2감압부(400)의 승강감압홀(401)은 내측에 가이드돌기(231)가 삽입되어서 안내되는 복수의 안내홈(402)이 분산되게 형성된다. 이러한, 안내홈(402)은 승강감압홀(401)의 상단에서 하단까지 형성된다. 따라서, 진동방지부(230)가 승강감압홀(401)에 삽입되면 가이드돌기(231)도 안내홈(402)들 중 어느 하나에 선택적으로 삽입된다. 이때, 진동방지부(230)를 승강감압홀(401)에 삽입시키면 가이드돌기(231)도 안내홈(402)에 삽입된다. 따라서, 가이드돌기(231)가 안내홈(402)에 삽입되면 감압판(410)의 감압홀(411)들이 마감감압판(420)의 감압홀(421)들에 서로 어긋나게 되고, 감압판(410)을 약간 회전시키는 상태에서 가이드돌기(231)가 다른 안내홈(402)에 삽입되면 감압판(410)의 감압홀(411)들이 마감감압판(420)의 감압홀(421)들에 마주되어서 연통되게 된다. 이와 같이, 감압홀(411)들이 감압홀(421)들에 어긋나게 되면 감압홀(411)들이 감압홀(421)들에 마주될 때 보다 난방수의 이동속도가 저하될 수 있다. Here, the lifting/decreasing hole 401 of the second pressure reducing unit 400 is formed so that a plurality of guide grooves 402 guided by inserting guide protrusions 231 are dispersed therein. These guide grooves 402 are formed from the upper end to the lower end of the elevation/decompression hole 401 . Therefore, when the anti-vibration unit 230 is inserted into the lifting/depressing hole 401, the guide protrusion 231 is also selectively inserted into any one of the guide grooves 402. At this time, when the anti-vibration part 230 is inserted into the lifting/depressing hole 401, the guide protrusion 231 is also inserted into the guide groove 402. Therefore, when the guide protrusion 231 is inserted into the guide groove 402, the pressure reducing holes 411 of the pressure reducing plate 410 are displaced from the pressure reducing holes 421 of the finished pressure reducing plate 420, and the pressure reducing plate 410 ) is slightly rotated, when the guide protrusion 231 is inserted into the other guide groove 402, the pressure reducing holes 411 of the pressure reducing plate 410 face the pressure reducing holes 421 of the closing pressure plate 420, to become connected In this way, when the pressure-reducing holes 411 are out of alignment with the pressure-reducing holes 421, the moving speed of the heating water may be lowered than when the pressure-reducing holes 411 face the pressure-reducing holes 421.

간격유지부(430)는 감압판(410) 및 마감감압판(420)에 양단이 지지되면서 감압판(410) 및 마감감압판(420)의 두께(직경)보다 작은 두께(직경)로 형성된다. 따라서, 감압판(410)을 통과한 유체가 간격유지부(430)에 충돌되거나 간섭되지 않으면서 마감감압판(420)로 이동된다. The gap maintaining part 430 is formed with a thickness (diameter) smaller than the thickness (diameter) of the pressure reducing plate 410 and the pressure reducing plate 420 while both ends are supported by the pressure reducing plate 410 and the pressure reducing plate 420 to finish. . Therefore, the fluid passing through the pressure reducing plate 410 moves to the closing pressure reducing plate 420 without colliding with or interfering with the gap maintaining part 430 .

그리고, 간격유지부(430)에는 진동방지부(230)가 관통되는 홀이 형성된다. 이러한, 간격유지부(430)의 홀은 제2감압부(400)의 승강감압홀(401)에 연통되어 진동방지부(230)가 관통된다. In addition, a hole through which the anti-vibration unit 230 passes is formed in the gap maintaining unit 430 . The hole of the gap maintaining part 430 communicates with the lifting and lowering pressure hole 401 of the second pressure reducing part 400 so that the anti-vibration part 230 penetrates.

이러한, 간격유지부(430)는 감압판(410)의 하부에 상부가 연결되어서 일체화될 수 있다. 따라서, 감압판(410)들을 밸브시트(130)에 순차적으로 안착시키면 감압판(410)의 하부에 형성된 간격유지부(430)들에 의해 감압판(410)들 및 마감감압판(420)의 이격된 상태가 유지된다. The upper portion of the gap maintaining unit 430 may be integrated with the lower portion of the pressure reducing plate 410 . Therefore, when the pressure reducing plates 410 are sequentially seated on the valve seat 130, the pressure reducing plates 410 and the pressure reducing plate 420 are separated by the gap maintaining parts 430 formed below the pressure reducing plate 410. The separated state is maintained.

또한, 간격유지부(430)는 원통형태나 블록형태로 형성되면서 복수로 구성되어 감압판(410)들의 사이에 위치되고 감압판(410) 및 마감감압판(420)의 사이에 위치된다. 따라서, 감압판(410)들의 이격된 상태 및 감압판(410) 및 마감감압판(420)의 이격된 상태가 유지될 수 있다. In addition, the gap maintaining part 430 is formed in a cylindrical shape or a block shape, and is composed of a plurality and is positioned between the pressure reducing plates 410 and positioned between the pressure reducing plate 410 and the closing pressure plate 420. Accordingly, the spaced state of the pressure reducing plates 410 and the spaced state of the pressure reducing plate 410 and the pressure reducing plate 420 may be maintained.

따라서, 간격유지부(430)에 의해 감압판(410)들의 사이와 감압판(410) 및 마감감압판(420)의 사이에 공간이 형성되므로, 유체가 공간들을 순차적으로 통과하면서 압력이 감압된다. 즉, 유체가 감압판(410)에 형성되는 좁은 감압홀(411)을 통과한 후에 감압홀(411)보다 넓은 공간으로 관류되면서 감압된 후에 마감감압판(420)을 통과 하게 된다. Therefore, since a space is formed between the pressure reducing plates 410 and between the pressure reducing plate 410 and the finished pressure reducing plate 420 by the space keeping unit 430, the pressure is reduced while the fluid sequentially passes through the spaces. . That is, after the fluid passes through the narrow pressure reducing hole 411 formed in the pressure reducing plate 410, it flows through a space wider than the pressure reducing hole 411 and passes through the pressure reducing plate 420 after being reduced in pressure.

더욱이, 간격유지부(430)는 감압판(410)들의 간격이나 감압판(410) 및 마감감압판(420)의 간격을 유지시킬 수 있는 길이로 제작됨이 바람직하다. Furthermore, it is preferable that the distance maintaining part 430 is manufactured to a length capable of maintaining the distance between the pressure reducing plates 410 or the distance between the pressure reducing plate 410 and the finished pressure reducing plate 420 .

또한, 간격유지부(430)는 외주면에 다수의 감압턱(431)이 일정간격으로 이격되게 형성된다. 따라서, 감압판(410)을 통과한 유체가 간격유지부(430)의 감압턱(431)에 충돌되면서 추가로 감속될 수 있다. In addition, a plurality of pressure reducing jaws 431 are formed on the outer circumferential surface of the gap maintaining unit 430 at regular intervals. Accordingly, the fluid passing through the pressure reducing plate 410 may be additionally decelerated while colliding with the pressure reducing jaw 431 of the gap maintaining part 430 .

이와 같이, 사용자가 승강샤프트(220)를 상승시키면 플러그(210)가 상승되어서 밸브시트(130)를 개방하게 된다. 그러면, 유체가 밸브바디(100)의 유입구(110)를 통해 유입되어서 제1감압부(300)를 통과하면서 1차로 유체의 압력이 감압된다. 그리고, 1차로 감압된 유체가 플러그(210)의 사이를 통해서 밸브시트(130)로 이동된다. 이때, 진동방지부(230)가 제2감압부(400)의 승강감압홀(401)에 삽입된 상태이므로, 밸브시트(130)로 이동하는 유체가 플러그(210)에 충돌되어도 플러그(210)의 진동이 방지된다. 또한, 1차로 감압되어서 밸브시트(130)로 유입되는 유체가 제2감압부(400)를 통과하면서 2차로 감압된 후에 배출구(120)로 배출된다. 따라서, 유체가 1차 및 2차로 감압되어서 배출되므로 유체가 배출되는 과정에서 밸브바디(100)를 손상시키지 않게 된다. In this way, when the user lifts the lifting shaft 220, the plug 210 is lifted to open the valve seat 130. Then, the fluid is introduced through the inlet 110 of the valve body 100 and the pressure of the fluid is first reduced while passing through the first pressure reducing unit 300 . Then, the first pressure-reduced fluid is moved to the valve seat 130 through the gap between the plugs 210 . At this time, since the anti-vibration part 230 is inserted into the lifting/decreasing hole 401 of the second pressure reducing part 400, even if the fluid moving to the valve seat 130 collides with the plug 210, the plug 210 vibration is prevented. In addition, the first depressurized fluid flowing into the valve seat 130 is secondly decompressed while passing through the second decompression unit 400 and then discharged through the outlet 120 . Therefore, since the fluid is first and secondly decompressed and discharged, the valve body 100 is not damaged during the discharge of the fluid.

이와 같은, 본 발명은 밸브를 개방하는 과정에서 고압으로 급격하게 유입되는 유체의 압력을 감압하여 유체가 밸브바디를 지속적으로 가격하여 피로가 누적되어서 파손됨을 방지할 수 있으므로, 밸브장치에 적용되어서 널리 사용될 수 있는 매우 유용한 발명이라 할 수 있다. As described above, the present invention can prevent damage due to accumulation of fatigue caused by the fluid continuously hitting the valve body by reducing the pressure of the rapidly flowing fluid at high pressure in the process of opening the valve, so it is widely applied to valve devices. It can be said to be a very useful invention that can be used.

본 발명이 속하는 기술분야의 당업자는 본 발명이 그 기술적 사상이나 필수적 특징을 변경하지 않고서 다른 구체적인 형태로 실시될 수 있다는 것을 이해할 수 있을 것이다. 그러므로 이상에서 기술한 실시예는 모든 면에서 예시적인 것이며 한정적인 것이 아닌 것으로서 이해되어야 하고, 본 발명의 범위는 상세한 설명보다는 후술하는 청구범위에 의하여 나타내어지며, 청구범위의 의미 및 범위 그리고 그 등가개념으로부터 도출되는 모든 변경 또는 변형된 형태가 본 발명의 범위에 포함되는 것으로 해석되어야 한다.Those skilled in the art to which the present invention pertains will understand that the present invention may be embodied in other specific forms without changing its technical spirit or essential features.
