Description

압력게이지 보호용 개폐 밸브{The opening and closing valve for protecting the pressure gauge.}The opening and closing valve for protecting the pressure gauge.

본 고안은 압력게이지 보호용 개폐밸브에 관한 것으로, 특히 배출압력을 감압배출 시킴과 동시에 이물질의 유입을 방지함으로써 압력게이지의 고장과 파손을 방지하게된 개페밸브에 관한 것이다.The present invention relates to an open / close valve for protecting a pressure gauge, and more particularly, to an open / close valve that prevents a breakdown and breakage of a pressure gauge by preventing the inflow of foreign substances while simultaneously discharging the discharge pressure under reduced pressure.

종래에도 보일러 등의 압력탱크에는 탱크내의 압력을 알 수 있도록 압력게이지를 장착사용하고 있음은 주지와 같으며, 상기 압력탱크로부터 배출되는 압력에 의해 압력게이지가 파손 또는 고장이 유발되는 것을 방지하기 위한 압력게이지 보호용 밸브도 다양한 기구적 구성의 것들이 제시되어 있다.Conventionally, it is well known that pressure gauges such as boilers are equipped with a pressure gauge so as to know the pressure in the tank, and to prevent damage or failure of the pressure gauge caused by the pressure discharged from the pressure tank. Pressure gauge protective valves are also available in a variety of mechanical configurations.

도 1은 압력게이지를 보호할 수 있는 종래 밸브의 대표적 구성을 예시한 것으로, 본 출원인에 의해 실용신안 등록 제165909호(출원번호 제97-24490호 1999년 8월 30일)로 제시되었으며, 근래에 가장 널리 사용되고 있다.Figure 1 illustrates a representative configuration of a conventional valve that can protect the pressure gauge, was proposed by the applicant as utility model registration No. 165909 (Application No. 97-24490 August 30, 1999), Is most widely used.

여기서는 밸브본체(1)의 내부에 저지격벽(2,2')을 형성시켜 배출압이 현저히 감압된 상태로 상향 이동 되도록 하고, 밸브본체(1) 상단의 나사부(3) 내에는 밸브공(4)을 보유한 밸브(5)를 설치하여, 압력게이지(6)가 분리된 상태에서 밸브(5)가 상향 이동하여 압력의 누출이 방지되도록 하였다.In this case, the barrier ribs 2 and 2 'are formed inside the valve body 1 so that the discharge pressure is moved upward with a significantly reduced pressure, and the valve hole 4 is formed in the threaded portion 3 of the upper end of the valve body 1. ), The valve 5 is installed, and the valve 5 is moved upward while the pressure gauge 6 is separated to prevent leakage of pressure.

따라서, 압력게이지(6)를 상기 나사부(3)에 나사결합 시키게 되면, 압력게이지(6) 하단의 개로돌기(7)가 밸브(5) 상단의 요입부(8)를 하향 가압함으로써 밸브(7)가 하향 이동하여 밸브공(4)을 개방시키게 되었다.Accordingly, when the pressure gauge 6 is screwed into the threaded portion 3, the opening projection 7 at the lower end of the pressure gauge 6 presses down the recessed portion 8 at the upper end of the valve 5 so that the valve 7 ) Moved downward to open the valve hole (4).

그런데, 상기한 종래 압력게이지 보호용 밸브는 탱크 내부압력의 급격한 배출에 의한 압력게이지(13)의 고장 또는 파손을 방지 할 수는 있으나, 압력게이지(13)의 고장상태를 육안으로 확인할 수 없다는 문제점이 지적된다.By the way, the conventional pressure gauge protective valve can prevent the failure or breakage of the pressure gauge 13 due to the rapid discharge of the internal pressure of the tank, but the problem that the failure state of the pressure gauge 13 cannot be visually confirmed. Is pointed out.

즉, 압력게이지(13)가 밸브본체(1)와 결합된 상태에서 사용중 고장이 발생하는 경우, 작업자는 밸브본체(1) 내부에 이물질이 적층되어 에어통로를 폐색 시킨 것인지 또는 압력게이지(13) 자체가 고장인지 알아낼 수 없다는 문제점이 그것이다.That is, when a failure occurs during use in the state in which the pressure gauge 13 is coupled with the valve body 1, the operator has accumulated the foreign matter inside the valve body 1 to block the air passage or the pressure gauge 13 The problem is that it can't figure out if it is faulty.

또한, 밸브본체(1)의 내부 에어통로가 폐색된 경우에도 상기와 동일한 결과를 초래하게 되는데, 이러한 문제점들은 탱크압의 한계압력이 초과하여도 고장을 확인하지 못할 경우, 보일러 등 기기전체의 파손은 물론 폭발 등의 또다른 사고를 유발하게 된다는 문제점도 지적된다.In addition, even if the internal air passage of the valve body (1) is blocked, the same result as above, these problems are caused, if the failure is not confirmed even if the limit pressure of the tank pressure is exceeded, damage to the whole equipment such as boiler Of course, the problem that will cause another accident, such as an explosion is pointed out.

상기한 문제점의 해소방안에 하나로 밸브본체의 일측에 개폐밸브를 설치 한 것도 사용되고 있으나, 이 경우에는 밸브의 개폐를 위해 수회반복하여 개폐손잡이를 정,역회동시켜야 하므로 작업이 지연된다는 문제점이 유발된다.In order to solve the above problem, one of the valves on one side of the valve body is used. However, in this case, the operation is delayed since the opening and closing handles must be repeatedly and repeatedly rotated several times to open and close the valve. .

본 고안은 상기한 문제점들을 감안하여, 압력게이지가 결합된 상태에서 밸브본체의 개폐상태를 육안으로 확인할 수 있도록 함으로써 밸브본체 또는 압력게이지의 정상작동 여부를 알 수 있음은 물론, 이물질이 밸브 본체 또는 압력게이지로 유입되는 것을 방지하여 압력게이지의 고장발생요인을 근본적으로 해소시킬 수 있는 압력게이지 보호용 개폐밸브를 제공함에 그 목적이 있다.In view of the above problems, the present invention allows the naked eye to check whether the valve body or the pressure gauge is normally operated by visually confirming the open / closed state of the valve body in a state where the pressure gauge is coupled. It is an object of the present invention to provide an on / off valve for protecting a pressure gauge that can prevent the inflow of the pressure gauge so as to fundamentally solve the failure factor of the pressure gauge.

상기 목적을 효과적으로 달성하기 위하여 본 고안에서는 밸브본체의 대략 중간부위에 형성시킨 감압부의 일측에, 레버의 선택회동에 의해 개폐되는 밸브 조립체를 설치함으로써 밸브본체의 개폐 여부를 육안으로 확인 할 수 있도록 하고, 상기 밸브본체 상부의 나사부에는 이물질을 여과하는 필터를 설치함으로써 이물 유입에 의한 압력게이지의 고장이 방지되도록 하였다.In order to effectively achieve the above object, the present invention provides a visual inspection of whether the valve body is opened or closed by installing a valve assembly that is opened and closed by selective rotation of the lever on one side of the pressure reducing part formed at approximately an intermediate portion of the valve body. In order to prevent the failure of the pressure gauge due to the inflow of foreign substances, a filter for filtering the foreign substances is installed in the threaded upper portion of the valve body.

이하에서 상기 본 고안의 양호한 실시예를 첨부도면에 의해 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail by the accompanying drawings.

도 2는 본 고안이 적용된 압력게이지 보호용 개폐밸브(V)를 나타낸 조립단면도로서, 도 3에서는 밸브조립체(13)의 구성을 분해사시도로 나타내었다.Figure 2 is an assembled cross-sectional view showing a pressure gauge protective valve (V) to which the present invention is applied, Figure 3 shows the configuration of the valve assembly 13 in an exploded perspective view.

상기 개폐밸브(V)는 밸브본체(10)의 상, 하부에 나사부(11,11')가 형성되어 압력게이지(6)와 압력탱크측 파이프(도시되지 않음)이 나사결합 설치됨은 종래와 동일하다.The on-off valve (V) is formed on the upper and lower portion of the valve body 10, the screw portion (11, 11 ') is formed so that the pressure gauge 6 and the pressure tank side pipe (not shown) is screwed installed is the same as the conventional Do.

상기 밸브본체(10)의 대략 중간부위에는 저지격벽(12a,12b)에 의해 그 사이에 에어통로(12c)가 형성되는 감압부(12)가 구성되고, 밸브본체(10)의 외면에는 밸브조립체(13)의 조립을 위한 보스부(14)가 구비된다.A pressure reducing part 12 is formed at an approximately middle portion of the valve body 10 by means of a stopping partition 12a and 12b, and an air passage 12c is formed therebetween, and on the outer surface of the valve body 10, a valve assembly is provided. A boss portion 14 for assembling 13 is provided.

상기 밸브조립체(13)는, 선단의 테이퍼형 헤드부(15)에 밸브공(15a)을 구비하고 후단의 걸림부(16) 외면에는 나사부(16a)를 형성시킨 밸브축(17)과, 상기 밸브공(15a)에 대응하는 통공(18a,18b)을 구비하여 헤드부(15)의 외면을 포삽하도록 보스부(14)의 내단에 안착 고정되는 개폐캡(18)과, 패킹(19)과 함께 보스부(14)에 체결되어 밸브축(17)의 이탈을 방지하는 고정너트(20)와, 상기 걸림부(16)가 관통하는 걸림구멍(21)을 보유하고 그 외면에는 제한돌기(22a,22b)를 구비한 개폐레버(22)와, 와셔(23)와 함께 상기 나사부(16a)에 체결 고정되어 개폐레버(22)의 분리를 방지하는 체결너트(24)로 구성된다.(도3 참조)The valve assembly (13) includes a valve shaft (17) having a valve hole (15a) in the tapered head portion (15) at the front end and a threaded portion (16a) formed at the outer surface of the locking portion (16) at the rear end. An opening / closing cap (18) provided with through holes (18a, 18b) corresponding to the valve holes (15a) and fixed to the inner end of the boss portion (14) so as to insert the outer surface of the head portion (15); A fixing nut 20 which is fastened to the boss portion 14 and prevents the valve shaft 17 from being separated, and a locking hole 21 through which the locking portion 16 penetrates, and a limiting protrusion 22a on the outer surface thereof. And an opening and closing lever 22 having a 22b, and a fastening nut 24 which is fastened and fixed together with the washer 23 to the screw portion 16a to prevent separation of the opening and closing lever 22. (Fig. 3). Reference)

한편, 밸브본체(10)의 상부측 나사부(11)의 내부에는 여과망(25')을 포함하는 필터(25)가 착탈 가능하도록 나사결합 설치된다.On the other hand, the inside of the upper threaded portion 11 of the valve body 10 is screwed so that the filter 25 including the filter net 25 'is detachable.

이와같은 구성의 본 고안은 압력게이지(6)가 분리된 상태에서 개폐레버(22)를 밸브본체(10)와 직교방향이 되도록 하여 밸브축(17) 선단의 헤드부(15)에 형성된 벨브공(15a)이 개폐캡(18)의 통공(18b)과 어긋나게 위치되도록 함으로써 압력손실을 방지하게 된다.According to the present invention, the valve hole formed in the head portion 15 at the tip of the valve shaft 17 is made to be orthogonal to the valve body 10 while the pressure gauge 6 is separated. The pressure loss is prevented by placing the 15a in a position offset from the through hole 18b of the opening / closing cap 18.

또한, 압력게이지(6)를 밸브본체(10)의 나사부(11)에 결합시킨 경우에는 도2에서와 같이 개폐레버(22)를 밸브본체(10)와 동일방향으로 전환시켜 주게 된다.In addition, when the pressure gauge 6 is coupled to the threaded portion 11 of the valve body 10, the opening and closing lever 22 is switched in the same direction as the valve body 10 as shown in FIG.

이경우에는 헤드부(18)의 밸브공(15a)이 개폐캡(18)의 통공(18a,18b)들과 일치하게 되므로 압력탱크의 압력이 통공(18a)과 밸브공(15a) 및 통공(18b)을 통과한후 압력게이지(6) 측으로 이동하여 압력탱크의 압력을 압력게이지(6)가 표시하게 된다.In this case, since the valve hole 15a of the head portion 18 coincides with the through holes 18a and 18b of the opening / closing cap 18, the pressure of the pressure tank is the through hole 18a and the valve hole 15a and the through hole 18b. After passing through), the pressure gauge 6 moves to the pressure gauge 6, and the pressure gauge 6 displays the pressure of the pressure tank.

이때, 압력탱크측으로부터 배출되는 압력은 저지격벽(12a,12b) 사이의 감압통로(12C)를 통과한 후, 통공(18a)과 밸브공(15a) 및 통공(18b)을 차례로 통과하며 서서히 이동하게 되므로, 급격한 압력배출에 의한 압력게이지(6)의 고장 또는 파손 우려는 해소된다.At this time, the pressure discharged from the pressure tank side passes through the decompression passage 12C between the barrier ribs 12a and 12b, and then gradually moves through the through hole 18a, the valve hole 15a and the through hole 18b. Therefore, the risk of failure or breakage of the pressure gauge 6 due to rapid pressure discharge is eliminated.

이와같이 밸브본체(10)에 조립된 개폐레버(22)의 위치에 따라 밸브본체(10)의 개폐여부를 육안으로 확인할 수 있으므로 작업자는 압력게이지(6)의 정상작동여부를 쉽게 파악할 수 있으며, 신속한 개폐전환이 이루어 지므로 작업효율의 대폭향상이 가능하게 된다.In this way, according to the position of the opening and closing lever 22 assembled in the valve body 10 can be visually confirmed whether the valve body 10 is opened or closed, the operator can easily determine the normal operation of the pressure gauge (6), and quickly Since switching is made, the operation efficiency can be greatly improved.

한편, 장기간 사용시에는 압력탱크로부터 미세한 불순물들이 압력게이지(6) 측으로 유출될 수 있는데, 이러한 이물질들은 밸브본체(10) 상단의 나사부(11)에 조립된 필터(25)에 의해 여과 되므로 이물유입에 의한 압력게이지(6)의 고장요인은 근본적으로 해소 되며, 청소시에는 압력게이지(6)를 분해하고 필터(25)를 나사부(11)로 부터 분리시킨 후 세척을 실시하여 재사용 하게 된다.On the other hand, in the long-term use, fine impurities may flow out from the pressure tank to the pressure gauge 6 side, and these foreign substances are filtered by the filter 25 assembled in the threaded portion 11 of the upper end of the valve body 10 so The failure factor of the pressure gauge 6 is basically solved, and when cleaning, the pressure gauge 6 is disassembled and the filter 25 is separated from the threaded portion 11 to be washed and reused.

이상의 설명에서와 같이 본 고안은 밸브본체(10)의 일측에 밸브조립체(13)가 설치되어 밸브(V)의 개폐를 신속 용이하게 임의 조절할 수 있음은 물론, 개폐여부를 육안확인할 수 있으므로 유지,보수 및 관리의 용이함과 함께 안전사고를 미연에 방지할 수 있고, 밸브본체(10)내에 필터(25)가 설치되어 이물유입에 의한 압력게이지(6)의 고장 및 파손을 방지할 수 있는등의 유용한 효과가 있다.As described in the above description, the present invention is provided with a valve assembly 13 installed at one side of the valve body 10 so that the opening and closing of the valve V can be easily and arbitrarily controlled, as well as whether the opening and closing can be checked visually. In addition to the ease of maintenance and management, safety accidents can be prevented in advance, and a filter 25 is installed in the valve body 10 to prevent breakage and damage of the pressure gauge 6 due to foreign material inflow. It has a useful effect.
