[0002] In the coke oven production process, the pressure regulation of the carbonization chamber is very important. There are many problems with the traditional coke oven carbonization chamber pressure regulation device.

[0003] In the past, pressure regulating devices were often complex in structure design, resulting in high manufacturing and maintenance costs. In addition, their sealing performance was poor, and they were prone to leakage, affecting production efficiency and product quality. For example, the outlet shape and sealing method of some valves were unreasonable, resulting in poor sealing effect and easy leakage of gas or liquid. In terms of controlling the flow in and out, the control accuracy of traditional devices was low and could not be accurately adjusted according to production needs. At the same time, the circulation system design of traditional devices was not perfect, for example, the circulation of ammonia water was not smooth enough, which affected the stability and reliability of the entire system.

[0004] In addition, the driving method of traditional devices is inefficient, the operation is not flexible and convenient enough, and it is difficult to meet the requirements of fast, precise and efficient modern production.

[0005] In summary, the existing coke oven carbonization chamber pressure regulating device has a series of deficiencies in structure, sealing, flow control, circulation and drive, and a new type of pressure regulating water seal fan valve is needed to solve these problems in order to improve the efficiency and quality of coke oven production.

[0008] Preferably, the valve tube is formed by bending an integral rectangular cylindrical structure, the back side of the valve tube is an arc-shaped structure, the upper end of the valve head is an arc-shaped structure, the valve tube and the valve head are an integrated structural tube body that is sealed end to end, and the volume of the valve head is larger than that of the valve tube.

[0009] Preferably, the outlet at the front end of the valve head is circular, and a sealing gasket for improving the sealing effect is attached around the inner side of the circular outlet at the front end of the valve head, and the sealing gasket is a chamfered structure.

[0010] Preferably, the valve core is a connecting piece with an arc-shaped rectangular structure at the bottom and a triangular structure at both ends.

[0011] Preferably, the circulation mechanism comprises an ammonia water circulation inlet hole and an ammonia water circulation outlet hole arranged on the back side of the valve pipe.

[0012] Preferably, the driving mechanism includes a crankshaft arranged outside the movable shaft, and the other end of the crankshaft is connected to a hydraulic driving machine. The hydraulic driving machine controls the rotation of the crankshaft so that the movable shaft controls the valve core to rotate in the valve head wall to control the flow in and out.

[0013] The beneficial effect of the utility model is that through the integrated design of the valve pipe and the valve head, it can be directly interchanged with the original bridge pipe without changing the connection form and installation size of the original coke oven riser and the gas collecting chamber, which greatly saves the transformation cost. The hydraulic drive machine controls the rotation of the valve core through the crankshaft and the movable shaft. The operation is simple and the response is fast. It can achieve fast and accurate flow regulation.
