Description

Technical Field

[0001] The utility model belongs to the technical field of leveling seats, in particular to a leveling seat of a single carbonization chamber raw gas pressure regulating valve. Background Art

[0002] Coke oven, a furnace usually made of refractory bricks and refractory blocks, is used to char coal to produce coke. The kiln that uses coal to make coke is the main thermal equipment for coking. Modern coke ovens refer to horizontal chamber coke ovens that are mainly used to produce metallurgical coke and can recover coking chemical products. They are composed of a furnace body and auxiliary equipment. The coke oven body consists of the furnace top, combustion chamber and carbonization chamber, chute area, heat storage chamber and other parts, which are connected by flues and chimneys. The basic structure of modern coke ovens is roughly the same, but due to different coal loading methods, heating methods and fuels used, they can be divided into many types.

[0003] The single carbonization chamber raw gas pressure regulating valve is usually installed between the bridge pipe and the gas collecting pipe. The regulating valve usually includes an internal regulating valve device and an external valve body. The connection between the lower end of the valve body and the gas collecting pipe needs to be sealed to prevent raw gas leakage. The water seal valve is a commonly used sealing device. For example, the lower end of the valve body is inserted into the groove of the side wall of the water seal valve, and the lower end of the valve body is immersed in the groove by liquid, so as to prevent the gas from passing through and achieve the sealing effect. However, since the pressure regulating valve is in a suspended state and is easy to tilt, a leveling device is required for leveling. Generally, 3 to 4 leveling seats are installed in the circumferential direction of the pipeline for adjusting the verticality and horizontality between each other. However, the commonly used leveling seats are complex in structure and the leveling effect is not good. Utility Model Content
