For the above-mentioned deficiency of the prior art, the utility model provides that a kind of sealing effect is good, the simple damping of structure
Spring safety valve.
To achieve the above object of the invention, the technology employed by the present utility model is
There is provided a kind of damping spring safety valve comprising valve body offers movable chamber in valve body, is provided with work in movable chamber
Plug, piston include integrally formed piston head and piston rod, seal head are provided on piston head, seal head is up big and down small circle
Cone, and the air inlet close fit opened up with movable chamber bottom offer gas outlet on the side wall of movable chamber；The one of piston rod
Fixed block is run through at end, and the upper cover of piston rod between fixed block and seal head is equipped with spring；The upper end of fixed block is positioning chamber, positioning
Intracavitary to be provided with locating piece, locating piece is connect with positioning chamber inner thread, and the upper end of locating piece is provided with cross plum blossom trough；Air inlet
Mouth lower end is connected with one section of helix tube, and the end of helix tube is provided with connector.
Further, one section of air inlet pipe is arranged on air inlet, air inlet pipe is threadedly coupled with air inlet；The upper end of air inlet pipe
With seal head close fit, lower end is connect with helix tube.
Further, the lower end of air inlet pipe is provided with hexagonal boss.
Further, locating piece upper end is provided with one section of hexagon prism, and the top of hexagon prism offers cross plum blossom trough.
The utility model has the following beneficial effects: this programme is used for the safety valve that depressurizes in oxygen preparation, when use, passes through
Connector is mounted on pipeline, and when the air pressure in pipeline is higher than the rated pressure value of safety valve, spring is compressed, and seal head is beaten
It opens, carries out pressure release；Since there may be molten errors on air inlet, lead to air inlet out-of-flatness, so seal head is using upper big
Under small cone reduce the error of safety valve, while sealing effect is good；Helix tube is used for damping, reduces pipeline in oxygen preparation
The influence to safety valve is shaken, the service life of safety valve is increased, reduces error；Since spring is become smaller using elastic force for a long time,
The locating piece of upper end setting positions piston for assisting, and keeps constant the rated pressure of pressure reducing valve.
Air inlet pipe is set on air inlet, the length of movable chamber can be protruded by adjusting air inlet pipe to adjust the elastic force of spring,
And then the rated pressure of pressure reducing valve is adjusted, to be suitable for different pressure relief ranges；Hexagonal boss in air inlet pipe facilitates rotation
Air inlet pipe is conveniently adjusted；On locating piece be arranged one end hexagon prism, upper end be arranged cross plum blossom trough, can by different tools come
Rotational positioning block is adjusted simply, conveniently.
The utility model is designed reasonably, structure is simple, effectively avoids pressure reducing valve in use by shaking institute
Bring error, while service life is increased, sealing effect is good.

Specific embodiment
Specific embodiment of the present utility model is described below, in order to facilitate understanding by those skilled in the art
The utility model, it should be apparent that the utility model is not limited to the range of specific embodiment, to the common skill of the art
For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in,
These variations are it will be apparent that all utilize the innovation and creation of the utility model design in the column of protection.
As shown in Figure 1, damping spring safety valve includes valve body 1, movable chamber 6, setting in movable chamber 6 are offered in valve body 1
There is piston, piston includes integrally formed piston head 15 and piston rod 16, and seal head 11, seal head 11 are provided on piston head 15
For up big and down small cone, and the air inlet close fit opened up with 6 bottom of movable chamber, offered on the side wall of movable chamber 6
Gas outlet 10；Fixed block 8 is run through in one end of piston rod 16, and fixed block 8 is fixed by connecting with 6 inner thread of movable chamber；
