工作原理：working principle:
在离心压缩机开始工作阶段，由于内部温度并没有升高，内部温度没有达到温控阀的设定值，自力式温度调节阀17内的感温液体受冷收缩带动阀芯18回缩，弹簧20在自身弹力作用下推动推块19带动锁杆11运动至窄口段13，此时，锁杆11的密封圈14将壳体出口10关闭，风冷***的气体无法从壳体出口10排出，风冷***无法运行，避免了前期因风冷***运行导致的气体分流及压 缩效率损失，提高了前期的压缩效率。待离心压缩机工作一段时间内部温度升高后，内部温度超过温控阀的设定值后，自力式温度调节阀17内的感温液体受热膨胀带动阀芯18伸长，阀芯18推动推块19、推块19的台阶21压缩弹簧20，带动锁杆11运动至宽口段12将壳体出口10打开，此时风冷***的气体可从壳体出口10排出，风冷***运行对离心压缩机内部进行降温。When the centrifugal compressor starts to work, since the internal temperature does not rise and the internal temperature does not reach the set value of the temperature control valve, the temperature-sensitive liquid in the self-operated temperature control valve 17 is cooled and shrinks to drive the valve core 18 to retract, and the spring 20 pushes the push block 19 under the action of its own elastic force to drive the locking rod 11 to move to the narrow mouth section 13, at this time, the sealing ring 14 of the locking rod 11 closes the housing outlet 10, and the gas of the air cooling system cannot be discharged from the housing outlet 10 , the air-cooling system cannot operate, avoiding the gas diversion and loss of compression efficiency caused by the operation of the air-cooling system in the early stage, and improving the compression efficiency in the early stage. After the centrifugal compressor has been working for a period of time, the internal temperature rises, and when the internal temperature exceeds the set value of the temperature control valve, the temperature-sensitive liquid in the self-operated temperature regulating valve 17 is heated and expands to drive the valve core 18 to elongate, and the valve core 18 pushes Block 19, the step 21 of push block 19 compresses the spring 20, drives the lock lever 11 to move to the wide mouth section 12 to open the shell outlet 10, at this time the gas of the air cooling system can be discharged from the shell outlet 10, and the air cooling system is running Cooling of the inside of the centrifugal compressor.
