Abstract
The utility model relates to a pneumatic actuator of a lubricating oil pressure tank air supply valve. The pneumatic actuator comprises a filter, a pressure reducing valve, an atomized lubricator and a reversing valve, and is characterized in that an inlet of the filter is connected with an air source, an outlet of the filter is connected with an inlet of the pressure reducing valve, an outlet of the pressure reducing valve is connected with an inlet of the atomized lubricator, an outlet of the atomized lubricator is connected with an inlet of the reversing valve, and two outlets of the reversing valve are respectively connected with a head cavity and a bottom cavity of a valve body of the lubricating oil pressure tank air supply valve. According to the pneumatic actuator of the lubricating oil pressure tank air supply valve, the lubricating oil pressure tank air supply valve is controlled by the pneumatic actuator, and control power of the air supply valve is effectively reduced. The pneumatic actuator of the lubricating oil pressure tank air supply valve is simple in structure, reliable in operation, and convenient to maintain.
Description
Technical field
The utility model relates to actuator, specifically the pneumatic actuator of lubricating oil pressure storage tank steam supply valve.
Background technique
Fully and effectively lubricate is the assurance of machinery normal operation and the key of life-saving, especially modern production line, the equipment such as its large size bearing, gear often provide thin oil lubricant by centralized system, because most equipment are worked under the industrial and minerals such as high speed, heavy duty, impact, and are very high to lubricating requirement.For prevent that equipment turns round in the situations such as power down, urgency are stopped, pump is bad under unlubricated condition, lubrication system has increased the lubricating oil pressure storage tank when design, in order to the lubricant oil of a few minutes in case of emergency is provided.Existing lubricating oil pressure storage tank adopts the straight ejector half pneumatic valve control of electromagnetism usually, and when normally producing, this pneumatic valve is in to get electricity condition always, and source of the gas is cut off, and the lubricating oil pressure storage tank keeps pressure; In case of emergency, the pneumatic valve dead electricity, approximately the pressurized air of 0.5MPa leads to the lubricating oil pressure storage tank, and lubricant oil is sent to each lubricating point with certain pressure, keeps the lubricated of a few minutes.Since be in for a long time during electricity condition, the temperature of electromagnetic coil and circuit board is higher, easily causes the faults such as electric control panel burns, spool is blocked, the inner gas blowby of air valve, the impact safety in production.Therefore design a kind of simple in structure, reliable, easy to maintenance and effectively to reduce the pneumatic actuator of lubricating oil pressure storage tank steam supply valve of steam supply valve power ratio control very necessary.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, reliable, easy to maintenance and can effectively reduce the pneumatic actuator of the lubricating oil pressure storage tank steam supply valve of steam supply valve power ratio control.
For achieving the above object, the utility model adopts following technological scheme: a kind of pneumatic actuator of lubricating oil pressure storage tank steam supply valve, comprise filter, reduction valve, oil sprayer and selector valve, the entrance that it is characterized in that filter is connected with source of the gas, the outlet of filter is connected with the entrance of reduction valve, the outlet of reduction valve is connected with the entrance of oil sprayer, the outlet of oil sprayer is connected with the entrance of selector valve, and two outlets of selector valve are connected with bottom chamber with the head chamber of lubricating oil pressure storage tank steam supply valve valve body respectively.
Further, in such scheme, described selector valve is solenoid directional control valve.
Further, in such scheme, described filter, reduction valve and oil sprayer are pneumatic triple piece.
The utility model adopts pneumatic actuator control lubricating oil pressure storage tank steam supply valve, effectively reduces the steam supply valve power ratio control.The utility model is simple in structure, reliable, easy to maintenance.
