The invention provides an oil mist lubricating device for an adjusting valve and belongs to the technical field of oil mist lubrication. The oil mist lubricating device for the adjusting valve comprises an air supply pipe, diameter-changing mechanisms, a plurality of suction pipes and flow meters. One end of the air supply pipe is connected with an air pump, and the other end of the air supply pipe is connected with a pneumatic adjusting valve. The air supply pipe is provided with a plurality of variable-diameter pipes. The diameter-changing mechanism is arranged on the variable-diameter pipesand used for changing the inner diameter of the variable-diameter pipes. One end of each suction pipe communicates with the side wall of the corresponding variable-diameter pipe, and the other end ofeach suction pipe is connected with an oil tank used for loading lubricating oil. The suction pipes are used for conveying the lubricating oil into the air supply pipe. The flow meters are arranged on the suction pipes and used for metering the flow of the lubricating oil in the suction pipes. By the adoption of the oil mist lubricating device for the adjusting valve, when the pressure difference between the air supply pipe and the variable-diameter pipes is larger than the force needed by sucking the lubricating oil in the oil tank into the variable-diameter pipes through the suction pipes,the lubricating oil is sucked into the variable-diameter pipes to form oil mist, and then elements in the pneumatic adjusting valve are lubricated and prevented from getting stuck.
Description
technical field [0001] The invention belongs to the technical field of oil mist lubrication, and more specifically relates to an oil mist lubrication device for a regulating valve. Background technique [0002] Control valve, also known as control valve, in the field of industrial automation process control, is the final control element that changes the process parameters such as medium flow, pressure, temperature, liquid level, etc. by means of power operation by receiving the control signal output by the adjustment control unit. Generally, it is composed of an actuator and a valve. According to the characteristics of the stroke, the regulating valve can be divided into straight stroke and angular stroke; according to the power used by the actuator, it can be divided into three types: pneumatic regulating valve, electric regulating valve and hydraulic regulating valve. According to its functions and characteristics, it is divided into three types: linear characteristics, eq...
