Abstract
The invention discloses a dual shock absorption valve rod. The dual shock absorption valve rod comprises a shell, a valve base and a valve rod body. The valve base is arranged in the shell. One end of the valve rod body is connected to the valve base, and the other end of the valve rod body extends out of the shell. A limiting block is welded to the bottom of the valve rod body, is arranged in the valve base and can move along the inner wall of the valve base. A first spring is arranged between the limiting block and the valve base. A second spring is arranged between the valve base and the shell. A wear-resistant cushion is arranged between the valve rod body and the valve base. According to the scheme, the valve base is arranged in the shell, one end of the valve rod body is connected to the valve base, the other end of the valve rod body extends out of the shell, the limiting block is welded to the bottom of the valve rod body, the first spring is arranged between the limiting block and the valve base, the second spring is arranged between the valve base and the shell, and therefore in the use process, when the valve rod body bears force, borne pressure is relieved and reduced through the first spring, the valve rod body is shocked to conduct buffering and load discharge, the second spring further plays a role in shock absorption, it is ensured that the valve base is buffered, and the service life of the valve rod is greatly prolonged.
Description
Technical field
The present invention relates to a kind of dual shock absorption 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 valve rod increased the service life.
Technical solution of the present invention is achieved in that a kind of dual shock absorption 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.
Preferably, described valve rod is provided with seal ring with the shell place of matching.
Preferably, described shell is made up of alloy.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of dual shock absorption 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, guarantees that valve seat cushions, and improves the working life of valve rod greatly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram of a kind of dual shock absorption valve rod of the present invention;
Wherein: 1, shell; 2, valve seat; 3, valve rod; 4, limiting stopper; 5, the first spring; 6, the second spring; 7, wear-resistant pad; 8, seal ring.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is a kind of dual shock absorption valve rod of the present invention, comprises shell 1, valve seat 2 and valve rod 3; It is inner that described valve seat 2 is arranged on shell 1; Described valve rod 3 one end is connected on valve seat 2, and the other end stretches out shell 1; Described valve rod 3 bottom welding limited location block 4; Described limiting stopper 4 is arranged in valve seat 2, can move along valve seat 2 inwall; The first spring 5 is provided with between described limiting stopper 4 and valve seat 2; The second spring 6 is also provided with between described valve seat 2 and shell 1; Wear-resistant pad 7 is also provided with between described valve rod 3 and valve seat 2; Described valve rod 3 is provided with seal ring 8 with shell 1 place of matching; Described shell 1 is made up of alloy.
The present invention program is inner by valve seat 2 being arranged on shell 1, valve rod 3 one end is connected on valve seat 2, the other end stretches out shell 1, valve rod 3 bottom welding limited location block 4, the first spring 5 is provided with between limiting stopper 4 and valve seat 2, the second spring 6 is also provided with between valve seat 2 and shell 1, during use, when valve rod 3 is stressed, pressure slows down decompression via the first spring 5, and valve rod 3 shakes buffering and unloads power, and the second spring 6 further plays cushioning effect, guarantee that valve seat 2 cushions, improve the working life of valve rod 3 greatly.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
