Description

TECHNICAL FIELD

[0001] The utility model relates to the pressure regulation field of coke oven carbonization chamber, concretely to a sealed pneumatic carbonization chamber pressure single valve with high stability. BACKGROUND

[0002] The single regulating valve is a valve that can only regulate flow in one direction. Its function is to reduce the pressure of the medium to a certain value, or to raise the temperature of the medium to a specified temperature. The function of this valve is to change the size of the passage cross section to control the flow through the passage.

[0003] The single valve is usually composed of a circular ring-shaped valve body and a valve plate. The valve plate serves as an opening and closing member and is opened by rotating the valve rod. The valve plate is arranged in the cylindrical passage of the valve body. The disc-shaped valve plate rotates around the axis at an angle of 0° to 90°. When the valve plate is rotated to 90°, the valve is in a fully open state. The distal end of the valve rod is connected to a pneumatic device for driving.

[0004] However, the existing single valve has the following problems: 1. When the valve plate is closed, the pressure of the liquid or gas is very high, which can easily damage the device. 2. When the valve is closed, the valve body and the valve plate do not directly contact and are stuck, and under the impact of the pressure of the liquid or gas, the valve plate is easy to loosen or damage.

[0019] In order to make the personnel in the technical field better understand the technical scheme in the utility model, the following will combine the drawing in the embodiment of the utility model, and the technical scheme in the embodiment of the utility model is described clearly and completely, obviously, the described embodiment only is a part of the embodiment of the utility model, and is not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the utility model.

[0020] For example, Figure 1 ​​As shown, a highly stable, sealed pneumatic carbonization chamber pressure regulating valve includes an annular valve body 1 mounted on the inner wall of the pneumatic carbonization chamber inlet pipe, and a valve plate 2 disposed within the valve body 1 and rotating within the valve body 1. Both sides of the valve body 1 are provided with arc-shaped baffles 3, and fine-tuning ports 4 are provided on both sides of the valve plate 2 at positions corresponding to the baffles 3. The arc-shaped baffles 3 on both sides of the valve body 1 ensure direct contact and locking between the valve plate 2 and the baffles 3 when the valve is closed, preventing the valve plate from loosening or being damaged due to pressure impacts from liquids or gases. The fine-tuning ports 4 on the valve plate 2 act as a buffer during the closing process, preventing excessive pressure at the moment of closure.

[0021] The baffle and valve body 1 are curved surfaces that fit tightly against the rounded corners of the outer edge of valve plate 2.

[0022] The pneumatic carbonization chamber inlet pipe is also equipped with a drive mechanism that drives the valve plate 2 to rotate. The valve rod is driven to rotate by a cylinder device, thereby opening or closing the valve plate.

[0023] like Figure 2 As shown, the driving mechanism includes a mounting bracket 5 mounted on the air inlet pipe of the pneumatic carbonization chamber, a swing arm 6 mounted on the rotating shaft of the valve plate 2, and a cylinder 7 mounted on the mounting bracket 5 to drive the swing arm 6 to swing. The cylinder body end of the cylinder 7 is rotatably connected to the upper end of the mounting bracket 5, and the piston rod end of the cylinder 7 is rotatably connected to the end of the swing arm 6. A cylinder is used as the drive, and the cylinder is connected to the rotating shaft of the valve plate 2 via the swing arm 6, driving the valve plate to rotate.

[0024] When the valve plate is fully open, the flow area is at its maximum, allowing the largest possible flow of liquid or gas. As the valve approaches closure, it enters a fine-tuning section. Liquid or gas flows through the fine-tuning port on the valve plate, allowing it to close slowly and preventing excessive pressure at the moment of closure. When the valve plate is at a 90° position, the valve is fully closed. The valve plate and baffle fit perfectly, directly contacting and locking. Driven by a cylinder, the piston's movement speed can be easily adjusted by controlling the flow and pressure of compressed air entering the cylinder. The cylinder uses compressed air as its power source. Using air as the medium, it avoids the environmental pollution problems associated with oil leaks found in hydraulic systems.

[0025] Cylinder 7 can also be replaced by a rotary pneumatic actuator, electric actuator, or hydraulic actuator.

[0026] like Figure 2 As shown, the fine adjustment port 4 is groove-shaped. The groove shape of the fine adjustment port 4 creates a notch on the outer cylindrical surface of the valve plate 2. When the valve is close to closing, the valve enters the fine adjustment section. Liquid or gas flows through the fine adjustment port on the valve plate, allowing the valve plate to close slowly and preventing excessive pressure at the moment of closing.

[0027] likeFigure 1 and 2 As shown in the figure, the valve plate 2 is provided with a water seal pipeline 8 for controlling water seal pressure. The water seal pipeline 8 passes through the valve plate 2 in the middle, and one end of the water seal pipeline 8 communicates with the space on one side of the valve plate 2, and the other end of the water seal pipeline 8 communicates with the space on the other side of the valve plate 2. When the high-pressure ammonia water in the pipeline is higher than the height of the water seal pipeline, the high-pressure ammonia water will flow out through the water seal pipeline.

[0028] If the water seal is not set, the water seal is not set under the coke oven bridge pipe, one is that the pressure control is not accurate, and two is that the high-pressure ammonia water will overflow into the coke oven and damage the coke oven. The water seal pipeline is arranged on the valve plate, which plays a role in controlling the water seal pressure and protecting the coke oven, and the height of the water seal pipeline can be selected according to the water seal pressure requirement.

[0029] In the description of the utility model, it is necessary to explain that the terms "left", "right", "up", "down" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0030] In the description of the utility model, it is necessary to explain that, unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
