이와 같이 된 본 발명은 가스밸브(3)를 구성하는 밸브본체(30)가 하측관체(30')와 상측관체(30")로 분할 구성되어 상호 연결부에 나사부가 형성되어 나사결합되므로, 개폐볼장치실(30a)의 분해결합이 용이하여 개폐볼(31)의 삽탈이 용이하고, 하측관체(30') 주벽에 개폐볼장치실에 연통하는 지지관(32)이 형성되어 지지관(32)의 개폐볼장치실쪽 입구에서 결합축(33d)이 외향하게 개폐볼작동봉(33)을 끼워 넣으면 개폐볼작동봉(33)이 지지관의 중심공에 끼워져 결합턱(33a)은 지지관 중심공 입구에 형성된 결합부(32a)에 결합하여 단턱(32')에 걸림되어 제자리 회전하므로 바깥쪽으로 빠질 염려가 없고, 개폐볼작동봉(33) 외주면에 피복한 오링(33c)이 지지관 중심공에 밀착하게 되므로, 개폐볼작동봉과 지지관 중심공 사이로 가스누출이 방지되게 되어 작동봉을 안전하게 장치할 수 있고, 이어서 볼시트와 개폐볼을 투입하여 개폐볼의 결합홈(31a)에 개폐볼작동봉의 결합돌부(33b)를 결합시킨 후, 개폐볼 작동봉 외측 결합축(33d)에 손잡이(5)의 연결봉(5a)의 결합홈(5b)을 체결볼트(6)를 결합하면, 손잡이와 개폐볼작동봉을 일체가 되게 연결할 수 있어 손잡이를 회전시켜 개폐볼을 회전시킬 수 있게 되고, 상측관체(30")를 결합하고, 엘보와 연결관을 조립하여 밸브를 완성할 수 있다.In the present invention as described above, the valve body 30 constituting the gas valve 3 is divided into a lower pipe body 30 ′ and an upper pipe body 30 ″, and a threaded portion is formed in the interconnection portion to be screwed together, so the opening/closing ball The disassembly and coupling of the device chamber 30a is easy, so that the opening/closing ball 31 is easily inserted and removed. When the opening/closing ball operating rod 33 is inserted with the coupling shaft 33d facing outward at the entrance to the opening and closing ball device chamber of the It is coupled to the coupling part 32a formed at the inlet and is caught on the step 32' and rotates in place, so there is no fear of falling out. Since it is closely attached, gas leakage is prevented between the opening/closing ball operation rod and the center hole of the support pipe, so that the operation rod can be safely installed. After coupling the coupling protrusion 33b, when the coupling groove 5b of the connection rod 5a of the handle 5 is coupled to the coupling shaft 33d of the outside coupling shaft 33d of the opening/closing ball actuating rod, when the coupling bolt 6 is coupled, the handle and the opening/closing ball The operating rod can be connected integrally, so that the opening and closing ball can be rotated by rotating the handle, the upper tube body 30 " is combined, and the elbow and the connecting tube are assembled to complete the valve.

또한, 손잡이연결봉이 접속하는 개폐볼작동봉(33)의 결합축에는 중심부에 직4각형결합구멍(7a)이 형성되고, 외주에 90도 방향으로 걸림돌기(7b)(7c)가 형성된 작동봉회전제동구(7)가 개입되어 개폐볼작동봉(33)이 회전할 때, 같이 회전하여 지지관(32)의 측방 걸림턱(32b) 상면과 하면에 걸림돌기(7b)(7c)가 번갈아 접촉하여 볼밸브의 회전각도를 제어하므로, 개폐볼을 개방하거나 닫는 작동을 정확하게 수행할 수 있어 가스통로로 공급되는 가스를 공급하고 차단하는 동작을 정확하게 할 수 있고, 작동봉회전제동구와 개폐볼작동봉 사이에 합성수지제패킹(8)이 개입되어 탄성을 발휘하므로, 작동봉회전제동구에 가해지는 충격을 완화시켜 자세를 안정시켜 주므로 이완을 방지할 수 있게 된다.
한편, 본 발명은 손잡이(5) 원형판의 외주에 상향으로 형성된 작동돌기(5c)가 있어서, 손잡이를 회전시킬 때 손잡이를 잡지 않고 작동돌기를 좌우로 밀어서 손잡이를 회전시킬 수 있으므로, 빈번하게 개폐볼을 개폐시켜야 할 때, 신속하게 개폐볼을 작동시킬 수 있는 이점이 있어 신속한 개폐가 가능하게 되고, In addition, on the coupling shaft of the opening/closing ball operation rod 33 to which the handle connection rod is connected, a rectangular engagement hole (7a) is formed in the center, and locking projections (7b, 7c) are formed on the outer periphery in a 90 degree direction. When the opening and closing ball actuating rod 33 rotates due to the intervening movement mechanism 7, the locking projections 7b and 7c alternately contact the upper and lower surfaces of the side locking jaws 32b of the support pipe 32 by rotating together. By controlling the rotation angle of the ball valve, the operation of opening or closing the opening/closing ball can be performed accurately, so that the operation of supplying and blocking the gas supplied to the gas passage can be accurately performed. Since the synthetic resin packing 8 is interposed therebetween to exert elasticity, the shock applied to the actuating rod rotating brake tool is relieved to stabilize the posture, thereby preventing relaxation.
On the other hand, in the present invention, there is an operating protrusion 5c formed upward on the outer periphery of the handle 5 circular plate, so that the handle can be rotated by pushing the operating protrusion left and right without holding the handle when rotating the handle. It has the advantage of quickly operating the opening and closing ball when opening and closing the
