Description

Technical Field

[0001] This invention relates to the field of hydraulic ball valve technology, and in particular to a hydraulic control ball valve with an emergency control mechanism. Background Technology

[0002] Hydraulic control ball valves control the opening and closing of the valve through a hydraulic transmission system. Their working principle is based on controlling fluid flow through the rotation of a ball. When an actuator (such as a hydraulic cylinder or motor) applies pressure, the valve stem drives the ball to rotate, thereby changing the relative position between the internal passage of the ball and the flow channel of the valve body, achieving fluid on / off control. Hydraulic control ball valves are widely used in various industrial fields such as petrochemicals, power, metallurgy, and water treatment. In the petrochemical industry, they are used for fluid control in systems such as oil and gas pipelines and chemical pipelines; in the power industry, they are used for water and steam flow control in equipment such as boilers, steam turbines, and water pumps; in the metallurgical industry, they are used for fluid control in the smelting processes of iron and steel and non-ferrous metals; and in the water treatment industry, they are used for fluid control in water treatment systems such as waterworks and sewage treatment plants.

[0003] When existing hydraulic control ball valves are in operation, if the hydraulic system malfunctions, the system cannot function properly, resulting in wasted repair time, potential economic losses, and even accidents. Therefore, we propose a hydraulic control ball valve with an emergency control mechanism to address these problems. Summary of the Invention

[0015] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention. Example

[0016] Reference Figures 1 to 6 This invention discloses a hydraulic control ball valve with an emergency control mechanism. The ball valve has a flange 2, to which a pipe 1 is fixedly connected. The pipe 1 can carry materials. A ball valve mechanism 3 is also fixedly connected to the pipe 1, controlling the opening and closing of the ball valve. The ball valve mechanism 3 includes a ball valve flange 31, a bearing 32, a sealing ring 33, a ball valve core 34, a ball bearing 35, a ball valve housing 36, and a groove 37. A connecting frame 4 is fixedly connected to the ball valve mechanism 3, connecting it to a hydraulic mechanism 5. A first fixing bolt 6 is fixedly connected to the lower edge of the connecting frame 4, and a second fixing bolt 6 is fixedly connected to the upper edge of the connecting frame 4. Two fixing bolts 7 fix the connecting frame 4, the ball valve mechanism 3, and the hydraulic mechanism 5 together. The upper side of the connecting frame 4 is fixedly connected to the hydraulic mechanism 5. The hydraulic mechanism 5 controls the rotation of the ball valve core 34. The hydraulic mechanism 5 includes a first hydraulic rod 51, a second hydraulic rod 52, a gear 53, a second rack 54, a first rack 55, and a hydraulic mechanism housing 56. The ball valve mechanism 3 is fixedly connected to a rotating rod 8. The rotating rod 8 connects the gear 53 and the ball valve core 34, so that the two rotate simultaneously. The rotating rod 8 is fixedly connected to a control handle 9. The control handle 9 allows the ball valve to still be controlled even if the hydraulic mechanism 5 is damaged, so as to avoid failure.

[0017] Pipeline 1 is fixedly connected to a ball valve housing 36, which protects and positions the ball valve core 34. A ball valve flange 31 and a connecting bracket 4 are fixedly connected to the upper side of the ball valve housing 36. A bearing 32 is fixedly connected to the ball valve housing 36, and a sealing ring 33 is installed below the bearing 32 to prevent material leakage. The ball valve core 34 is installed inside the ball valve housing 36 to control the passage of material. A ball bearing 35 is installed on the lower side of the ball valve core 34. The ball bearing 35 and the bearing 32 make the rotation of the ball valve core 34 smoother and prevent wear. A groove 37 is provided on the lower side of the inside of the ball valve housing 36 to allow the ball bearing 35 to roll. A rotating rod 8 is fixedly connected to the bearing 32. The rotating rod 8 is equipped with a sealing ring 33. The upper side of the ball valve core 34 is fixedly connected to the bottom of the rotating rod 8, and the ball bearing 35 is installed in the groove 37.

[0018] A hydraulic mechanism housing 56 is fixedly connected to the connecting frame 4. A first hydraulic rod 51 is fixedly connected to the lower side of the interior of the hydraulic mechanism housing 56. A second hydraulic rod 52 is installed on the rear side of the first hydraulic rod 51. A first rack 55 is slidably connected to the first hydraulic rod 51, and a second rack 54 is slidably connected to the second hydraulic rod 52. A gear 53 is rotatably connected to the second rack 54. The two hydraulic rods control the two racks to move simultaneously in opposite directions. The racks control the gear 53 to rotate, driving the ball valve core 34 to open and close. A gear 53 is fixedly connected to the rotating rod 8 on the side away from the ball valve mechanism 3, making the rotation of the gear 53 more stable. The gear 53 is rotatably connected to the first rack 55.

[0019] The rotating rod 8 is installed inside the connecting frame 4, and the first fixing bolt 6 is fixedly connected to the ball valve flange 31. The ball valve flange 31 is fixedly connected to the connecting frame 4, and the control handle 9 is installed in the middle of the connecting frame 4 for easy control of the rotating rod 8.

[0020] Working principle: In use, when the hydraulic mechanism 5 is opened, the first hydraulic rod 51 and the second hydraulic rod 52 in the hydraulic mechanism start working, driving the second rack 54 and the first rack 55 to move in two directions. The two racks drive the gear 53 to rotate, and the gear 53 drives the rotating rod 8 and the ball valve core 34 to rotate. At this time, the ball 35 begins to roll in the groove 37, and the bearing 32 begins to rotate. Both of these reduce the difficulty of rotating the ball valve core 34, and the opening of the ball valve core 34 rotates to the front of the pipe 1, allowing materials to pass through the ball valve mechanism 3. When closed, the two hydraulic rods start in opposite directions, and the opening of the ball valve core 34 rotates to the other side, closing the passage. When the hydraulic mechanism 5 malfunctions, turn the control handle 9. The control handle 9 drives the rotating rod 8 to rotate, and then, as described above, controls the opening and closing of the ball valve to prevent accidents.

[0021] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
