Railway turnout oil injection system

Abstract

The invention belongs to the technical field of oil pressure and flow control equipment and discloses a railway turnout oil injection system. The railway turnout oil injection system is provided witha valve body. An outer valve element is mounted in the valve body. The input end of the outer valve element is movably connected with a driving rod through a first spring. An inner valve element is sleeved inside the outer valve element. The inner valve element is internally provided with a metering space. A second spring is mounted in the metering space. A valve body cover matched with the innervalve element is mounted at the rear end of the valve body. The upper end of the valve body cover is provided with an oil inlet and an oil outlet. Oil outlet nozzles are mounted in the air inlet and the oil outlet. A pressure control flow valve is adopted to replace a traditional electromagnetic control flow valve to constitute the railway turnout oil injection system. A valve body electronic control component and a wire are omitted. Since an electromagnetic valve is omitted, power consumption of the system is reduced, and a lead storage battery and solar energy can be adopted for supplementary power. The railway turnout oil injection system integrates the advantages of mechanical power and electrostatic force, thereby reducing the cost and improving the reliability.

Description

technical field [0001] The invention belongs to the technical field of oil pressure and flow control equipment, and in particular relates to an oil injection system for railway turnouts. Background technique [0002] At present, the existing turnout oil injection system is divided into two types: mechanical power and electromagnetic power in terms of oil injection power. In the turnout locking movement. This oil injection device is mostly installed on the turnout, and the power comes from the movement of the turnout. When a failure occurs, it may affect the normal operation of the turnout. 2. Electromagnetic power: The oil injection system driven by electromagnetic power is generally realized by controlling the solenoid valves at each oil injection point, and generally consists of a control center, a pump station, and a power supply system. This oil injection system does not have any shortcoming in traditional technology, but with regard to this patent, just has some short...

AI Technical Summary

Problems solved by technology

[0004] (1) Turnout power extrusion type, when a fault occurs, it may affect the locking of the turnout, and the general installation position is limited

[0005] (2) The oil injection system driven by electromagnetic power has some disadvantages, such as high power consumption, complicated control and many faults

[0007] The significance of solving the above problems and defects is: based on the difficulty of the installation method, there is currently no suitable oil injection system for railway turnouts, and only a small number of turnouts are installed with oil injection systems for trial operation. Always endangering the safety of oil injection workers on the road
