The steam turbine is also called as a steam turbine engine, and is a rotary steam power device.A high-temperature high-pressure steam passes through a fixed nozzle to become an accelerated airflow and then is sprayed onto blades, so that a rotor provided with blade rows rotates, and simultaneously, the rotor does work outwards. Steam turbines are the main equipment of modern thermal power plants, and are also used in the metallurgical industry, chemical industry and ship power plants. During the working process of the steam turbine, hydraulic oil needs to be matched with the steam turbine to supply oil to components such as bearings. The oil in the hydraulic oil tank flows out from the oil suction port due to the change of working conditions, and returns to the hydraulic oil tank through the oil return port after reaching a working part, so that the hydraulic oil in the tank body is constantly consumed and fluctuates. Therefore, it is necessary to ensure that the hydraulic tank should be able to contain the hydraulic oil flowing into the hydraulic tank in the system when the hydraulic system is out of operation, and that the hydraulic tank should be kept at a proper level during operation. Generally, in order to ensure that the hydraulic oil tank has enough space to accommodate return oil, a breather is arranged on the tank body to release pressure; in order to ensure sufficient oil quantity and prevent air from being mixed in an oil way, the oil tank needs to be supplemented with oil regularly. However, when the existing respirator is used for pressure adjustment, the pressure in the box body is high, so that the air rushes out of the box body instantly, the suction force is high, and more external air is sucked.
