[0017] The present invention will be further described below with reference to the embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Please see Figure 1 and Figure 2 This utility model provides a double ball valve, including a pipe 1 and two balls 2 and 3 disposed on both sides inside the pipe 1. The balls 2 and 3 have the same structure. The three sides of the balls 2 and 3 are provided with channels 21. The pipe 1 is composed of a central support pipe 11 located in the middle, ball pipes 12 located on both sides, and flanges 13 fixed to the ends of the ball pipes 12. Protective shells 14 are fixedly installed on both sides of the support frame 9 outside the transmission assembly 4 and the transmission assembly 5. A protective shell 2 15 is provided above the support frame 9 and is sleeved on the support assembly 7 and the lifting module 8. The protective shells 14 and 2 15 protect the transmission assembly 4 and the transmission assembly 5.

[0020] In this embodiment, the three-sided channel 21 provided on the ball 1 2 and the ball 2 3 can realize the flow and cut-off of the medium in the straight pipe, and can also realize the connection and use of the T-shaped pipe, which improves the flexibility of the valve. The socket 11 is bolted to the ball pipes 12 on both sides, which facilitates the installation of the ball 1 2 and the ball 2 3 inside the pipe 1. The ball 1 2 and the ball 2 3 are installed inside the ball pipe 12 and can rotate inside the ball pipe 12.

[0021] Please see Figure 3 and Figure 4 The top of sphere 1 2 is provided with a transmission component 1 4 that extends through to the top of pipe 1, and the top of sphere 2 3 is provided with a transmission component 2 5 that extends through to the top of pipe 1. A small gear 6 that moves up and down is provided between transmission component 1 4 and transmission component 2 5. The small gear 6 is used for synchronous transmission between transmission component 1 4 and transmission component 2 5. Transmission component 1 4 and transmission component 2 5 have the same structure. Transmission component 1 4 includes a transmission rod 42 connected to the top of sphere 1 2, and a large gear 1 41 is fixedly installed on the outside of transmission rod 42. A connecting sleeve 43 is provided at the top of transmission rod 42, and a handle 44 is fixedly installed on one side of connecting sleeve 43. A large gear 2 51 is provided on the outside of transmission rod 42 of transmission component 2 5. The large gear 1 41 and the large gear 2 51 are located on both sides of the small gear 6 and are meshed. The transmission rod 42 drives the large gear 1 41 or the large gear 2 51 to rotate.

[0022] In this embodiment, the transmission component 4 drives the ball 2 to rotate inside the ball tube 12, and the transmission component 5 drives the ball 3 to rotate inside the ball tube 12. The operator holds the handle 44 and can use the connecting sleeve 43 to drive the transmission rod 42 to rotate. The transmission rod 42 drives the ball 2 or the ball 3 below to rotate, thereby realizing the opening, closing and reversing operation of the valve.

[0023] Please see Figure 5 A support frame 9 is fixedly installed above the pipe 1. Spring pieces 91 are fixedly installed on both sides of the top of the support frame 9. A bushing 92 is installed in the middle of the support frame 9. The bushing 92 is sleeved on the outside of the shaft 82 to guide the up and down movement of the shaft 82.

[0024] In this embodiment, the spring piece 91 is used to insert the second protective shell 15 into it from top to bottom, thereby limiting the position of the second protective shell 15 and improving the stability of the second protective shell 15 outside the support component 7 and the lifting module 8.

[0025] Please see Figure 5The support frame 9 has support components 7 on both sides of the top. The support components 7 include upright plates 71 fixed on both sides of the top of the support frame 9. Wedge blocks 72 are slidably arranged on the outer side of the upright plates 71. Handles 73 are fixedly installed on the top of the two wedge blocks 72. Horizontally arranged insert plates 74 are slidably inserted into the side of the upright plates 71. The insert plates 74 have slide tracks inside. A card seat 76 is fixedly installed at one end of the insert plate 74. A spring 75 is installed between the card seat 76 and the upright plate 71.

[0026] In this embodiment, the supporting component 7 is used to limit the lifting module 8, thereby ensuring that the pinion 6 is at a stable height. The operator holds the handle 73 and moves it downward, which can drive the wedge blocks 72 at both ends to descend, allowing the insert plates 74 on both sides to open to both sides at the same time, so that the card seat 76 separates from the card plate 1 83 or card plate 2 84. After the handle 73 drives the wedge blocks 72 to rise, under the rebound action of the spring 75, the card seat 76 is in close contact with the card plate 1 83 or card plate 2 84, ensuring the stability of the lifting module 8.

[0027] Please see Figure 5 A lifting module 8 is provided in the middle of the support frame 9, and the lower part of the lifting module 8 is connected to the pinion 6. The lifting module 8 includes a support base 81 fixed on the top outer wall of the pipe 1, and a shaft 82 is slidably inserted into the support base 81. A first clamping plate 83 and a second clamping plate 84 distributed vertically are fixedly installed on the upper outer side of the shaft 82, and a handle 85 is fixedly provided at the top of the shaft 82.

[0028] In this embodiment, the shaft 82 is fixedly connected to the pinion 6. By holding the handle 85, the shaft 82 can be driven to move up and down, thereby driving the pinion 6 to move up and down, so as to realize the separation and engagement adjustment of the pinion 6 with the first large gear 41 and the second large gear 51.

[0029] The working principle and usage process of this utility model: When operating the double ball valve of the pipeline, the operator can choose to operate the transmission component 1 4 and the transmission component 2 5 separately, or the valve can be opened and closed by operating either the transmission component 1 4 or the transmission component 2 5 and using the intermediate transmission of the pinion 6. When operating transmission assembly 1 (4) and transmission assembly 2 (5) separately, the operator holds handle 73, causing the wedge blocks 72 at both ends to descend. After the wedge blocks 72 descend, the insert plate 74 is moved horizontally. At this time, the spring 75 is compressed, and the insert plate 74 causes the card seat 76 to move outward, separating the card seat 76 from the card plate 2 (84). Then, the operator holds handle 85, causing shaft 82 to move upward. Shaft 82 causes pinion 6 to move upward synchronously, separating pinion 6 from the large gears 1 (41) and 2 (51) on both sides. At this time, the operator can rotate transmission assembly 1 (4) and transmission assembly 2 (5) to rotate independently, thereby using transmission assembly 1 (4) and transmission assembly 2 (5) to drive the lower ball 1 (2) and ball 2 (3) to rotate, realizing the opening and closing of the valve. When both transmission assembly 4 and transmission assembly 5 are operated simultaneously, the pinion 6 can be engaged with the large gears 41 and 51 on both sides according to the above adjustment method, thereby realizing the linkage operation.
