The utility model discloses a pneumatic valve structure of a boiler gas turbine, which comprises a gas valve cover, the bottom of the inner wall of the gas valve cover is provided with a rotating sliding block, the rotating sliding block is rotationally connected with the gas valve cover, the middle part of the bottom end of the rotating sliding block is fixedly connected with a connecting rod passing through the gas valve cover, the connecting rod is rotationally connected with the gas valve cover, the bottom of the connecting rod is fixedly connected with a valve plate, and the top sleeve of the rotating sliding block is provided with an extrusion block The top of the extrusion block is fixedly connected with a sealing plate, which is slidably connected with the inner wall of the air valve cover. The pneumatic valve drives the valve through the air pressure to make the valve rotate and achieve the closing effect. When the extrusion block set at the top of the valve is pressed downward, the sliding block moves with the chute, thus driving the sliding block on the top of the valve to rotate. The threaded rod set at the top of the extrusion block can be By turning, the length of the threaded rod in the inflation chamber is controlled according to the opening size of the valve, and the extrusion block is pressed, so that the valve can still be tightly closed when the pneumatic valve is cut off.
【技术实现步骤摘要】
一种锅炉燃机气动阀结构
本专利技术涉及一种气动阀结构,特别涉及一种锅炉燃机气动阀结构,属于阀门结构
技术介绍
锅炉是一种能量转换设备,向锅炉输入的能量对水进行加热升温,产生大量的水蒸气,锅炉输出具有一定热能的蒸汽,将热能转化为机械能,在锅炉燃机内,大量的蒸汽使锅炉内部气压增大,若长期不讲蒸汽排出,容易产生炸炉的风险,现有技术中,传统的锅炉燃机大多都是使用手动蝶阀进行排放蒸汽的,需要工人操作,由于蝶阀为金属材质制成,具有导热性,与蒸汽接触的蝶阀温度较高,工人的手容易被烫伤,因此,需要使用气动或者电动等驱动的阀门,现有技术中,传统的气动阀大多都是通过气压将阀门压下,达到断流的效果,在没有气压的情况下,容易反弹,因此,需要设计一种气动阀结构,能够在断气的状态下持续工作。
