Embodiment Construction

[0028] Below in conjunction with accompanying drawing, the present invention is described in further detail, and its content is to explain rather than limit the present invention:

[0029] like figure 1 , is a typical valve structure, including door stem 1, handwheel 2, copper sleeve 3, valve cover 4, one side is equipped with copper sleeve locating pin 5, for newly manufactured valves, the oil injection hole 10 is machined on the opposite side ; For the existing valve, transform the pin hole of the copper sleeve positioning pin 5 on the other side into an oil filling hole 10 and insert the oil filling pipe 11. The depth of the oil injection hole 10 penetrates through the inner ring of the copper sleeve 3 , and the aperture size is the same as that of the oil injection pipe 11 .

[0030] The lubricating system for prolonging the life of the valve copper sleeve of the present invention includes a casing 6, an oil delivery pump 7, a heater 8, a timer 9, an oil injection hole 10...

Abstract

The invention discloses a lubricating system for prolonging the service life of a valve copper bush and a working method thereof, and belongs to the technical field of valve technical improvement. Comprising a shell, an oil delivery pump, a heater, a timer, oil injection holes and oil injection pipes. The shell is fixed on the valve shell; the oil delivery pump, the heater and the timer are arranged in the shell; the oil filling hole penetrates through the valve shell and the copper sleeve; the oil filling pipe is mounted in the oil filling hole; an outlet of the oil delivery pump is connected with the oil injection pipe, and an inlet of the oil delivery pump is connected with the lubricating grease storage device through the oil delivery pipe. The timer is connected with the oil delivery pump and the heater. The valve copper bush can be automatically lubricated, and the service life of the valve is prolonged; meanwhile, the maintenance frequency is reduced, and the manpower and material resource cost is saved.

Description

technical field [0001] The invention belongs to the technical field of valve technical renovation, and in particular relates to a lubrication system and a working method for prolonging the service life of a copper sleeve of a valve. Background technique [0002] Valve is an important component in the industrial field with a wide range of applications and many classifications. It is mainly used as a control component in the pipeline fluid conveying system to change the passage section and the flow direction of the medium, and control the flow of the conveying medium. A device, It has the functions of diversion, cut-off, throttling, non-return, shunt or overflow pressure relief. The copper sleeve set in the valve is generally made of copper metal, and its hardness is lower than that of the shaft system. The main function is to lubricate, reduce friction, reduce friction, and protect the shaft. If the wear is too serious, the copper sleeve needs to be replaced. [0003] The ...
