Abstract
The invention discloses a dual damping lubricating valve rod which comprises a shell, a valve seat and a valve rod body. The valve seat is arranged in the shell. One end of the valve rod body is connected to the valve seat, and the other end of the valve rod body stretches out of the shell. A limiting block is welded to the bottom of the valve rod and arranged in the valve seat and can move along the inner wall of the valve seat. A first spring is arranged between the limiting block and the valve seat. A second spring is arranged between the valve seat and the shell. A wear-resisting gasket is arranged between the valve rod body and the valve seat. An oil guide pipe is arranged on the shell. One end of the oil guide pipe stretches into the valve seat, and the other end of the oil guide pipe stretches out of the shell and is sealed by a sealing cover. According to the scheme, during use, when the valve rod body is stressed, pressure borne by the valve rod body is relieved and reduced by the first spring, the valve rod body vibrates to buffer unloading force, the second spring further achieves the damping function, buffering of the valve seat is ensured, and the service life of the valve rod is greatly prolonged; and the oil guide pipe is used for adding lubricating oil to lubricate the valve seat, and the mobility of the valve seat is guaranteed.
Description
Technical field
The present invention relates to a kind of dual shock absorption lubrication valve rod, belong to plate valve technical field.
Background technique
Plate valve flashboard is pushed to outlet valve valve seat realization sealing by the pressure of valve inlet place medium, so firmly fasten plate valve not only can not play good seal action, on the contrary valve seat and flashboard are damaged to some extent, impact sealing, in using process, the unnecessary vibrations produced greatly reduce working life, and in real work, this phenomenon happens occasionally.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: proposing one can reduce machine vibration, the dual shock absorption lubrication valve rod increased the service life.
Technical solution of the present invention is achieved in that a kind of dual shock absorption lubrication valve rod, comprises shell, valve seat and valve rod; Described valve seat is arranged on enclosure; Described valve rod one end is connected on valve seat, and the other end stretches out shell; Described stem bottom is welded with limiting stopper; Described limiting stopper is arranged in valve seat, can move along valve base inner wall; The first spring is provided with between described limiting stopper and valve seat; The second spring is also provided with between described valve seat and shell; Also wear-resistant pad is provided with between described valve rod and valve seat; Described shell is provided with oil guide pipe; Described oil guide pipe one end is stretched in valve seat, and the other end stretches out shell and by seal cap sealing.
Preferably, described valve rod is provided with seal ring with the shell place of matching.
Preferably, described shell is made up of stainless steel.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of dual shock absorption lubrication valve rod of the present invention, by valve seat is arranged on enclosure, valve rod one end is connected on valve seat, the other end stretches out shell, stem bottom is welded with limiting stopper, the first spring is provided with between limiting stopper and valve seat, the second spring is also provided with between valve seat and shell, during use, when valve rod is stressed, pressure slows down decompression via the first spring, valve rod vibrations buffering unloads power, second spring further plays cushioning effect, guarantee that valve seat cushions, improve the working life of valve rod greatly, oil guide pipe is used for adding lubricant oil, lubricate to valve seat, ensure the mobility of valve seat.
