And a locking mechanism for selectively engaging the handle, the handle being pinned to the distal end of the rotating shaft so as to be able to angularly move upward and downward in a lever-wise manner, the handle locking device of the ball valve facilitates locking and unlocking of the handle. .

일반적으로 볼밸브나 버터플라이밸브와 같이 개폐구가 90도 범위에서 회전하면서 밸브의 유로를 개폐하는 밸브의 경우에 핸들이 막대형으로 설치되어 있고, 이 핸들의 선단부는 개폐구와 결합된 회전축의 선단부에 결합되어 핸들을 90도 범위에서 회전시킴으로서 밸브의 유로가 개폐되도록 되어 있다.In general, in the case of a valve that opens and closes the flow path of a valve while the opening and closing hole rotates in a 90 degree range, such as a ball valve and a butterfly valve, the handle is installed in a rod shape, and the tip of the handle is provided at the tip of the rotating shaft coupled with the opening and closing hole. In combination, the flow path of the valve is opened and closed by rotating the handle in a 90 degree range.

그러나 이와 같은 볼밸브나 버터플라이밸브의 경우에 핸들이 수평방향으로 길게 노출되어 있음에 따라 밸브 주변을 지나거나 작업을 하다가 부주의로 핸들을 건드리면 개폐구의 개폐를 원치 않았음에 도 불구하고 개폐구의 비정상적으로 개폐되는 문제점이 있었다.However, in the case of such a ball valve or butterfly valve, the handle is exposed in the horizontal direction, so if you inadvertently touch the handle while passing around the valve or working, There was a problem of abnormal opening and closing.

따라서 종래에 도 1 및 도 2에서 보는 바와같이 핸들을 록킹시키는 잠금장치가 개발되어 사용되고 있는데, 위와 같은 종래의 핸들잠금장치는 버터플라이밸브에 설치되어 사용되고 있다.Therefore, in the related art, as shown in FIGS. 1 and 2, a locking device for locking the handle has been developed and used. The conventional handle locking device as described above is installed and used in a butterfly valve.

즉, 종래의 버터플라이밸브는 밸브몸체(1)의 유로(2)에 개폐구(3)가 90도 방향으로 회전가능하게 설치되고, 이 개폐구(3)에는 회전축(4)이 수직방향으로 상향 설치되어 밸브몸체(1)의 상부로 노출되게 설치되며, 밸브몸체(1)의 상측으로 노출된 회전축(4)의 상단부에는 막대형의 핸들(5)이 수평방향으로 설치되어 있다.That is, in the conventional butterfly valve, the opening and closing hole 3 is rotatably installed in the flow path 2 of the valve body 1 in a 90 degree direction, and the rotating shaft 4 is installed upward in the vertical direction. The upper part of the rotating shaft 4 exposed to the upper side of the valve body 1 is installed to be exposed to the upper portion of the valve body 1, the rod-shaped handle 5 is installed in the horizontal direction.

그리고, 밸브몸체(1)의 상면에는 90도 간격으로 스토퍼(7)가 돌출되게 형성되고 양측 스토퍼(7) 사이의 외주면에 다수의 걸림홈(6)이 일정간격으로 형성된 걸림판(8)이 고정되게 설치되어 있고, 상기 핸들(5)의 하부에는 선단부가 상기 각각의 걸림홈(6)에 끼워져 걸리는 걸림구(9)가 구비된 보조손잡이(10)가 힌지핀(11)에 의해 집개식으로 설치되며, 힌지결합부 후방측의 핸들(5) 하부와 보조손잡이(10)의 후방 사이에는 스프링(12)이 탄력적으로 설치되어 있다.In addition, the stopper 7 is formed on the upper surface of the valve body 1 at 90-degree intervals, and the locking plate 8 having a plurality of locking grooves 6 formed at regular intervals on the outer circumferential surface between the two stoppers 7 is provided.

The supporting compression coil spring 18 is elastically installed.

상기와 같이 구성되어 있는 본 발명의 작용 관계를 도 3 내지 도 5를 참고하여 설명하면 다음과 같다.Referring to Figures 3 to 5 the operational relationship of the present invention configured as described above is as follows.

본 발명은 초기에 핸들을 조작시키지 않은 경우에 핸들(5)의 선단부와 걸림판(8)의 사이에 설치된 압축코일스프링(18)의 팽창탄력에 의해 힌지핀(14)에 의해 힌지결합된 핸들(5)의 선단부를 상측으로 밀어주게 되어 핸들(5)의 후방 손잡이부는 하측으로 내려가는 힘이 작용하여 힌지결합부 후방의 걸림구(9)가 걸림판(8)의 걸림홈(6)에 걸려 핸들(5)의 회전이 불가능한 상태이다.According to the present invention, the handle is hinged by the hinge pin 14 by the expansion elastic force of the compression coil spring 18 installed between the tip of the handle 5 and the engaging plate 8 when the handle is not operated initially. The front end of the handle (5) is pushed upward, so that the rear handle of the handle (5) acts downwardly, so that the locking hole (9) behind the hinge coupler is caught by the locking groove (6) of the locking plate (8). The rotation of the handle 5 is impossible.

이상태에서 핸들(5)을 돌리고자 하는 경우에는 핸들(5)의 후방 손잡이부를 잡고 상측으로 들어 올리면 이 핸들(5)은 회전축(4)의 상단부에 핸들(5)의 앞부분이 힌지핀(14)에 의해 힌지식으로 결합되어 힌지결합부를 중심으로 핸들(5)의 선단부가 아래쪽으로 내려가게 된다.If you want to turn the handle (5) in this state, hold the rear handle of the handle (5) and lift it upwards, the handle (5) is the upper end of the handle (5) hinge pin (14) on the upper end of the rotating shaft (4) It is hingedly coupled by the front end of the handle 5 is lowered around the hinge coupling portion.

이때 핸들(5)의 선단부 하측에는 경사부(15)를 형성하고 있어서 핸들(5)의 후방을 들어 올릴 때 선단부가 용이하게 아래쪽으로 내려가게 되며, 압축코일스프링(18)은 압축되게 된다.At this time, the inclined portion 15 is formed below the front end of the handle 5 so that the front end is easily lowered when lifting the rear of the handle 5, and the compression coil spring 18 is compressed.

위에서와 같이 힌지결합부의 후방측이 상측으로 들려 올라가기 때문에 힌지결합부의 후방에 형성된 걸림구(9)도 상측으로 올라가면서 걸림판(8)의 걸림홈(6)에서 이탈되어 핸들(5)을 좌측이나 우측으로 돌릴 수 있게 된다.Since the rear side of the hinge coupler is lifted upward as described above, the locking hole 9 formed at the rear of the hinge coupler is also lifted upward and separated from the locking groove 6 of the locking plate 8 to lift the handle 5. You can turn left or right.

상기와 같이 걸림구(9)의 걸림상태가 해제되므로 사용자가 목적하는 바대로 핸들(5)을 돌릴 수 있으며, 이렇게 핸들(5)을 돌리는 방향에 따라 개폐구(3)가 회전하면서 유로(2)를 열거나 또는 닫게 되는 것이다.Since the locking state of the latch 9 is released as described above, the user can turn the handle 5 as desired, and the opening and closing port 3 rotates according to the direction in which the handle 5 is rotated. Will open or close.

위에서와 같이 사용자가 원하는 바대로 핸들(5)을 돌린후 핸들(5)을 놓으면 핸들(5)의 선단부 하방과 걸림판(8) 사이에 탄력적으로 설치된 압축코일스프링(18)의 팽창력에 의해 핸들(5)의 앞부분이 상측으로 들려 올라가게 되고, 그와 동시에 힌지결합부를 중심으로 핸들(5)의 후단은 하측으로 내려가면서 위치조절된 위치의 걸림홈(6)에 걸림구(9)가 끼워져 위치조절된 상태에서 핸들을 돌릴 수 없게 된다.As above, turn the handle 5 as desired by the user and then release the handle 5 by the expansion force of the compression coil spring 18 elastically installed between the lower end of the handle 5 and the stopping plate 8. The front part of (5) is lifted upward, and at the same time, the rear end of the handle (5) around the hinge engaging portion is lowered downward and the locking hole (9) is inserted into the locking groove (6) in the position adjusted position. The handle cannot be turned while in the adjusted position.

본 발명에서 걸림구(9)의 후방에 걸림부(16)가 걸림구(9)와 일체로 형성되어 있는데, 이는 핸들(5)을 좌측이나 또는 우측으로 돌릴 때 한정된 각도 범위 내에서만 핸들(5)이 회전가능하도록 하는 양측 스토퍼(7)에 걸려서 한정된 각도범위를 벗어나지 않도록 하는 것이다.In the present invention, the locking portion 16 is formed integrally with the locking hole 9 at the rear of the locking hole 9, which is only within a limited angle range when the handle 5 is turned left or right. ) Is caught by both stoppers 7 so as to be rotatable so as not to be out of the limited angle range.

상기와 같이 본 발명의 볼밸브의 핸들잠금장치는 회전축의 상단부에 핸들의 앞부분을 힌지식으로 설치하여 핸들을 지렛대식으로 들어올릴 수 있게 한 뒤에 핸들의 힌지결합부 전방은 압축코일스프링을 탄력적으로 설치하고 핸들의 힌지결합부 후방 하측에는 걸림판의 걸림홈에 삽탈되는 걸림구를 일체형으로 형성함으로서, 핸들을 지렛대식으로 들어 올린 상태에서 회전시키는 간편한 동작으로 밸브의 유로를간편하게 개폐시킬 수 있음은 물론이고, 핸들의 걸림 및 해제 또한 간편하게 이루어 질 수 있는 효과가 있는 것이다.As described above, the handle locking device of the ball valve of the present invention installs the front part of the handle in a hinged manner at the upper end of the rotating shaft so that the handle can be lifted by a lever, and then the front of the hinge coupling part of the handle elastically compresses the compression coil spring. By installing and integrally forming a catch which is inserted into the catching groove of the catching plate in the lower part of the rear side of the hinge coupling part of the handle, the flow path of the valve can be easily opened and closed by the simple operation of rotating the handle in a raised state. Of course, the locking and release of the handle is also an effect that can be made easily.

또한, 종래와는 달리 핸들의 하측에 집게식으로 보조손잡이를 설치하지 않으므로 제작비용이 절감되어 타사 제품과의 경쟁력에서 앞설 수 있는 매우 유용한 효과가 있는 것이다.In addition, unlike the conventional method, since the auxiliary handle is not installed on the lower side of the handle by a forceps type, the manufacturing cost is reduced, and thus, a very useful effect can be achieved in the competitiveness with other companies' products.
