본 고안은 공기배출압력을 이용한 압력조절밸브에 관한 것으로, 배관내의 개폐밸브 1차측 유체압력을 임의의 설정압력으로 2차측에 기계적인 동작으로 자동공급 시킬 수 있는 공기압 조절부와 구동부를 간단한 구조로 구성하여서 된 것이다.The present invention relates to a pressure regulating valve using an air discharge pressure, and has a simple structure of the air pressure regulating part and the driving part which can automatically supply the fluid pressure of the on / off valve in the piping to the secondary side at an arbitrary set pressure. It is made up.
일반적으로 압력조절밸브를 조정하는 방법으로는 공압비례제어 장치가 사용되었으나 이는 감지부(트랜스미터), 지시조절부(콘트롤러), 위치제어부(포지쇼너), 구동부(콘트롤 밸브)가 각각 별도로 설치되어야 하므로 그 설치구조가 복잡하고 설치비용도 많이 드는 결점이 있었다.In general, a pneumatic proportional control device was used to adjust the pressure regulating valve. However, since a sensing part (transmitter), an indication control part (controller), a position control part (positioner), and a driving part (control valve) must be separately installed. The installation structure was complicated and the installation cost was high.
또한 그 구조가 비교적 간단한 파일로트식 감압변과 직동식 감압변이 있었으나 이는 자체 차압변동에 따른 설정압력변동이 발생하여 밸브의 압력조절 기능의 정확성이 떨어지는 결점이 있었다.In addition, there were pilot type pressure reducing valves and direct type pressure reducing valves, which were relatively simple in structure.
본 고안은 이와 같은 문제점을 해결하기 위하여 공기배출압력을 이용한 압력조절밸브를 구성시킨 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to configure the pressure control valve using the air discharge pressure to solve this problem described in detail by the accompanying drawings as follows.
공기압조절부(1)는, 중앙에 좌우로 곤통된 작동공기압실(10)을 형성하고 작동공기압실(10) 상하에 같은 체적의 설정압력실(15)과 감지압력실(16)을 각각 형성하여 그 내부에 연결축(12)으로 연결되어 서로 대향지지된 상하압판(13)(13')으로 압력조절이 이루어지게 한다.The air pressure regulating unit 1 forms an operating air pressure chamber 10 which is passed from side to side in the center and forms a pressure chamber 15 and a sensing pressure chamber 16 having the same volume above and below the operating air pressure chamber 10, respectively. It is connected to the inside by the connecting shaft 12 to the pressure control to the upper and lower pressure plates 13, 13 'supported by each other.
상기 작동공기압실(10)은 일측 유입부에 오리피스(10a)가 형성되어 공기압공급부(4)와 공기압로(6)로 연결되고 유출부는 공기압구동부(2)와 공기압로(8)로 연결된다.The working air pressure chamber 10 has an orifice 10a formed at one inlet part, and is connected to the air pressure supply part 4 and the air pressure path 6, and the outlet part is connected to the air pressure drive part 2 and the air pressure path 8.
설정압력실(15)은 중앙에 횡격막(14)을 설치하여 상하로 분리구획시킨 다음 압력실 상부 일측에 블리드구멍(17)을 형성하고 상부 중앙은 압력설정용계기(40)를 거쳐 공기압공급부(4)와 공기압로(5)로 연결되어 압력설정용계기(40)로 설정압력을 유입시키며, 압력실 하부는 상부압판(13)이 횡격막(14)에 일체로 부설되고 일측에 배기공(18)과 노즐구멍(11)을 형성한다.The pressure chamber 15 has a diaphragm 14 in the center thereof and is divided up and down. Then, the bleed hole 17 is formed at one side of the upper side of the pressure chamber. 4) is connected to the pneumatic path (5) to flow the set pressure to the pressure setting instrument 40, the lower part of the pressure chamber is the upper pressure plate 13 is integrally attached to the diaphragm 14 and the exhaust hole 18 on one side ) And the nozzle hole 11 are formed.
감지압력실(16)은 중앙의 횡격막(14')으로 상하 분리구획되어 상부에 하부압판(13')이 횡격막(14')에 일체로 부설되고 배기공(18')을 형성하며, 하부중앙은 유체압관로부(3)의 2차측(34)과 보조유체압로(9)로 연결된다.The sensing pressure chamber 16 is divided up and down by a central diaphragm 14 'so that the lower pressure plate 13' is integrally attached to the diaphragm 14 'at the top and forms an exhaust hole 18'. Is connected to the secondary side 34 of the fluid pressure passage 3 and the auxiliary fluid pressure path (9).
공기압구동부(2)는, 폐변피스톤(25)과 개변피스톤(22)(23)이 일체로 연결된 폐변피스톤실(24)과 2중개변피스톤실(21)(21')을 각각 구성하고 폐변피스톤실(24)은 공기압공급부(4)와 공기압로(7)로 연결되며 개변피스톤실(21)(21')은 고정판(21a)으로 양쪽으로 분할형성되어 유입부는 작동공기압실(10)과 공기압로(8)로 연결되고 일측 개변피스톤실(21)의 유출부는 배기공(27)을 형성하며 개변피스톤(22)과 개폐피스톤(25) 연결부 사이에는 회동작동간(26)을 축설하여 유체압관로부(3)의 개폐밸브(31)와 밸브축(32)으로 연결한다.The pneumatic drive unit 2 constitutes a closed piston piston chamber 24 and a double intermediate piston piston chamber 21 and 21 'to which the closed piston piston 25 and the modified pistons 22 and 23 are integrally formed. The seal 24 is connected to the pneumatic pressure supply section 4 and the pneumatic path 7 and the modified piston chambers 21 and 21 'are divided into two sides by the fixed plate 21a so that the inlet portion is formed by the working air pressure chamber 10 and the pneumatic pressure. It is connected to the furnace (8) and the outlet of the one side opening piston chamber 21 forms an exhaust hole (27) between the opening of the opening piston (22) and the opening and closing piston (25) by accumulating the rotational operation interval (26) It is connected to the on-off valve 31 and the valve shaft 32 of the conduit (3).
유체압관로부(3)는, 관로(30) 내부의 중앙에 개폐밸브(31)를 설치하되 개폐밸브(31)의 좌측으로 유입부가 1차측(33)이고 우측으로 유출부가 2차측(34)이며 2차측(34) 상부 일측에 보조유체압로(9)로 감지압력실(16)에 연결시켜서 된 것이다.The fluid pressure passage 3 is provided with an on-off valve 31 in the center of the pipeline 30, the inlet part of which is the primary side 33 on the left side of the on-off valve 31, and the outlet part of the outlet side 34 on the right side. It is to be connected to the sensing pressure chamber 16 by the auxiliary fluid pressure path (9) on the upper side of the secondary side (34).
한편, 제4도는 공기압조절부(1)의 또다른 구성을 나타낸 것으로, 설정압력실(15)의 상부압판(13)을 스프링(41)으로 탄지하여 조정나사봉(42)으로 스프링(41)의 탄발력을 조절하되 스프링(41)으로 상부압판(13)의 설정압력을 조정할 수 있게 하여서된 것이다.On the other hand, Figure 4 shows another configuration of the pneumatic pressure control unit 1, the upper pressure plate 13 of the set pressure chamber 15 by holding the spring 41, the spring 41 to the adjustment screw rod 42 While adjusting the elasticity of the spring (41) is to be able to adjust the set pressure of the upper platen (13).
이와 같이된 본 고안은 제1도에서와 같이 공기압공급부(4)에서 일정압력(3∼7㎏/㎠)의 공기압로 (5)(6)(7)를 통하여 압력설정용계기(40)와 공기압조절부(1)의 작동공기압실(10) 및 공기압구동부(2)의 폐변피스톤실(24)로 각각 보내게 된다.The present invention as described above is the pressure setting instrument 40 and through the air pressure passage (5) (6) (7) of a constant pressure (3 ~ 7kg / ㎠) in the air pressure supply unit 4 as shown in FIG. It is sent to the working air pressure chamber 10 of the air pressure control unit 1 and the closed piston chamber 24 of the air pressure driving unit 2, respectively.
이때 압력설정용계기(40)에서는 유체압관로부(3)의 2차측(34) 압력을 설정하게 되는바, 그 설정압력범위는 공기압공급부(4) 보다 적은 압력이어야 한다.In this case, the pressure setting instrument 40 sets the pressure of the secondary side 34 of the fluid pressure pipe part 3, and the set pressure range should be less than the air pressure supply part 4.
예를들어 공기압공급부(4)의 압력이 5㎏/㎝일 경우에는 설정압력은 0.3∼5㎏/㎠의 범위내에서 설정이 이루어지게 된다.For example, when the pressure of the pneumatic pressure supply unit 4 is 5 kg / cm, the setting pressure is set within the range of 0.3 to 5 kg / cm 2.
한편, 작동공기압실(10)을 통과한 공기압은 공기압구동부(2)의 개변피스톤실(21)(21')로 유입되어 폐변피스톤실(24)과의 압력차에 의해 밸브축(32)과 연결된 회동작동간(26)을 피스톤작용으로 구동시켜 개패밸브(31)를 개폐시키므로 관로 2차측의 압력조정이 이루어지게 되는데 이는 공기압공급부(4)의 동일 압력이 개변피스톤실(21)(21')과 폐변피스톤실(24)로 유입되지만 개변피스톤실(21)(21')은 2중으로 설치되어 있어 2배의 공기압력을 갖게 되고 그 압력은 작동공기압실(10)의 노즐구멍(11)의 개폐여부에 따라 조절되는 것이며 이는 같은 체적으로된 설정압력실(15)과 감지압력실(16)의 압판(13)(13')평형상태가 될때 2차측압력은 설정압력과 같아진다.On the other hand, the air pressure passing through the working air pressure chamber 10 flows into the modified piston chambers 21 and 21 'of the air pressure driving unit 2, and the pressure between the valve shaft 32 and the valve shaft 32 due to the pressure difference between the closed piston chambers 24. By connecting the rotational operation section 26 by the piston action to open and close the bleed valve 31, the pressure adjustment on the secondary side of the pipeline is made, which is the same pressure of the air pressure supply unit 4 is modified piston chamber 21 (21 ') ) And the closed piston chamber (24), but the modified piston chamber (21) (21 ') is installed in two times to have a double air pressure and the pressure is the nozzle hole 11 of the working air pressure chamber (10) The pressure of the secondary side becomes equal to the set pressure when the platen 13 (13 ') of the set pressure chamber 15 and the sensing pressure chamber 16 are equalized.
제2도에서는 유체압관로부(3)의 1차측(33) 압력이 압력설정용계기(40)의 설정압력 이하로 되었을때 개폐밸브(31)가 열린 상태를 나타낸 것으로 즉, 설정압력 이하의 1차측(33) 압력이 2차측(34)의 보조유체압로(9)를 거쳐 감지압력실(16)에 유입된 압력은 하부압판(13')의 가압력을 감소시키므로 설정압력실(15)의 상부압판(13) 가압력에 의해 하강하여 작동공기압실(10)의 노즐구멍(11)을 차단함과 아울러 개변피스톤실(21)(21')양측에 유입되는 압력이 증가하여 폐변피스톤(25)에 의해 우측으로 회동작동간(26)을 가동시켜 개폐밸브(31)를 개방시킨다.2 shows the open / close valve 31 being opened when the pressure on the primary side 33 of the fluid pressure passage 3 is less than or equal to the set pressure of the pressure setting instrument 40. The pressure introduced into the sensing pressure chamber 16 through the auxiliary fluid pressure path 9 on the secondary side 34 through the secondary side 34 reduces the pressing force of the lower pressure plate 13 ', so that the set pressure chamber 15 The upper pressure plate 13 is lowered by the pressing force to block the nozzle hole 11 of the working air pressure chamber 10, and the pressure flowing into both of the modified piston chambers 21 and 21 'increases, so that the closed pistons 25 The opening and closing valve 31 is opened by activating the rotation operation section 26 to the right side by means of.
이와 같이 개방된 개폐밸브(31)에 의해 과도한 압력이 감지압력실(16)에 유입되면 감지압력실(16)의 하부압판(13')가 가압력이 설정압력실(15)의 상부압판(13)을 상승시켜 작동공기압실(10)의 노즐구멍(11)이 개방된다.When excessive pressure flows into the sensing pressure chamber 16 by the opening / closing valve 31 opened as described above, the lower pressure plate 13 ′ of the sensing pressure chamber 16 has a pressing force of the upper pressure plate 13 of the set pressure chamber 15. ), The nozzle hole 11 of the working air pressure chamber 10 is opened.
제3도는 상기와 같이 유체압관로부(3)의 1차측(33)에서 유입되는 압력이 과도하게 많아질 경우 감지압력실(16)의 하부압판(13')가 압력에 의해 설정압력실(15)의 상부압판(13)을 상승시켜 노즐구멍(11)이 개방되면 공기압공급부(4)의 공기압이 공기압구동부(2)로 유입되지 않고 노즐구멍(11)으로 빠져나가 배기공(18)으로 배출되므로 개변피스톤실(21)(21')이 압력이 감소하여 폐변피스톤(25)에 의해 좌측으로 회동작돈간(26)을 가동시켜 개폐밸브(31)를 닫아 관로(30)의 1차측(33) 유체압력을 차단하게 된다.FIG. 3 shows that when the pressure flowing from the primary side 33 of the fluid pressure passage part 3 is excessively increased, the lower pressure plate 13 ′ of the sensing pressure chamber 16 is set by the pressure. When the nozzle hole 11 is opened by raising the upper pressure plate 13 of 15), the air pressure of the air pressure supply part 4 does not flow into the air pressure drive part 2 but exits the nozzle hole 11 to the exhaust hole 18. Since the discharged piston chambers 21 and 21 'are reduced in pressure, the rotary piston 26 is operated by the closed piston 25 to the left to close the opening / closing valve 31 to close the primary side of the pipeline 30 ( 33) Shut off the fluid pressure.
즉, 제2도 및 제3도는 유체압관로부(3)의 1차측(33) 압력이 설정된 압력으로 2차측(34)으로 보내지는 과정에서 압력불균형이 발생할때 설정압력실(15)의 상부압판(13)과 감지압력실(16)의 하부압판(13')의 승하강으로 개변피스톤실(21)(21')에 유입되는 압력에너지를 가변시켜 이와 연동되는 피스톤으로 개폐밸브(31)의 개폐상태를 나타낸 일례로서 2차측(34)에 처음 압력을 공급할 때에는 개폐밸브(31)가 완전히 열리고 2차측(34)이 차단되었을 때에는 완전히 닫히게 된다.That is, FIGS. 2 and 3 show an upper portion of the set pressure chamber 15 when pressure imbalance occurs in the process in which the pressure of the primary side 33 of the fluid pressure passage 3 is sent to the secondary side 34 at the set pressure. The pressure valve flowing into the modified piston chambers 21 and 21 'by the lowering and lowering of the platen 13 and the lower pressure plate 13' of the sensing pressure chamber 16 is opened and closed with a piston linked thereto. As an example showing the open / close state of the valve, when the pressure is supplied to the secondary side 34 for the first time, the shut-off valve 31 is completely opened, and when the secondary side 34 is shut off, the valve is completely closed.
제1도에서와 같은 개폐밸브(31)의 위치는 설정계기 압력과 관로(30)의 1차측(33) 압력이 거의 동일할때를 나타낸 것으로, 1차측(33) 압력변동폭이 적으면 개폐밸브(31)의 움직임도 적어지나 1차측(33) 압력변동폭이 크면 개폐밸브(31)가 많이 움직여서 2차측(34) 압력을 조절시켜 주게 되는 것이다.The position of the on-off valve 31 as shown in FIG. 1 shows when the set pressure and the pressure of the primary side 33 of the conduit 30 are almost the same. When the primary side 33 pressure fluctuation range is small, the on / off valve (31) also less movement, but if the primary side 33 pressure fluctuation range is large, the on-off valve 31 moves a lot to adjust the secondary side 34 pressure.
또한, 제4도는 공기압조절부(1)의 설정압력을 스프링(41)으로 조절할 수 있게한 것으로 스프링(41)으로는 설정압력 변동폭을 넓게 하는데는 한계성이 있으나 통상적인 공기압공급부(4)의 압력보다 큰 압력으로 1차측(33) 압력을 2차측(34)으로 보낼때 사용하기가 편리한 이점이 있는 것이다.In addition, FIG. 4 shows that the set pressure of the air pressure control unit 1 can be adjusted by the spring 41. However, the spring 41 has a limitation in widening the set pressure fluctuation range, but the pressure of the conventional air pressure supply unit 4 is limited. There is an advantage that it is convenient to use when sending the primary side 33 pressure to the secondary side 34 at a higher pressure.
즉, 설정압력실(15)의 상부압판(13)을 스프링(41)으로 탄지하여 설정압력을 조절하므로 공기압공급부(4)를 압력부로는 공기압구동부(2)의 피스톤운동만을 하게 된다.That is, since the upper pressure plate 13 of the set pressure chamber 15 is held by the spring 41 to adjust the set pressure, only the piston movement of the pneumatic drive unit 2 is used as the air pressure supply unit 4 as the pressure unit.
이상과 같이 본 고안은 기계적인 작동으로 배관내의 개폐밸브 1차측 유체압력을 임의의 설정압력으로 2차측에 정확하게 자동공급시킬 수 있고 그 구조도 간단하므로 고장수리도 용이하고 그 설치비용도 절감할 수 있는 경제성과 정확한 압력조절을 할 수 있는 이점이 있는 것이다.As described above, the present invention can automatically supply the primary side fluid pressure of the on / off valve in the pipe to the secondary side at an arbitrary set pressure by the mechanical operation, and its structure is simple, so it is easy to troubleshoot and reduce the installation cost. Economy and accurate pressure control.
