In the utility model embodiment, the sheet body upper surface is provided with an annular relief, the second spring it is another
One end is located in annular relief.
In the utility model embodiment, the lower end of the central bolt is provided with ring segment, is located above ring segment successively
It is provided with the gasket and sheet body being set on central bolt.
In the utility model embodiment, the ring segment upper surface is provided with one and the matched annular in gasket lower face
Protrusion.
In the utility model embodiment, the ontology lower end is provided with intake tunnel, the diameter of the ring segment be less than into
The diameter of aquaporin, the diameter of the gasket are more than the diameter of intake tunnel.
In the utility model embodiment, sluice is provided in the middle part of the ontology, the diameter of the sluice is more than sealing
The diameter sheet body of pad, the diameter of the sheet body are more than the diameter of the gasket.
In the utility model embodiment, it is provided with and the matched through-hole of central bolt in the middle part of the locking nut.
A kind of safety valve of the utility model, has the advantages that:1, soft water effect, can reduce into water noise;2、
Impact of the flow to spring is reduced, product service life is extended;3, the madial wall filter screen of safety valve in the market can be cut, is saved
About cost.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, to the technical solution in inventive embodiments carry out it is clear,
It is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Reference explanation book attached drawing, a kind of safety valve, including ontology 10 and setting are in intrinsic central bolt 20, the ontology
On be provided with the matched locking nut 30 of central shaft, the close of ontology water inlet end water inlet can be opened and closed by being provided on the central bolt
Packing 40, be arranged on the central bolt with the matched sheet body 50 of ontology internal perisporium, offer on the sheet body for water
Water hole 51, the first spring 61 is provided between the sheet body and locking nut.
Specifically:The sheet body is set on central bolt;Second spring 62, the center are arranged on the central bolt
An annular groove 21 is provided on bolt, one end and the annular groove of the second spring are connected, the second spring it is another
It holds the end face with sheet body to be connected to be linked together sheet body and central bolt to realize.The sheet body upper surface is provided with a ring
The other end of shape lug boss 52, the second spring is located in annular relief.
In particular:The lower end of the central bolt is provided with ring segment 22, has been sequentially arranged above positioned at ring segment
The gasket and sheet body being set on central bolt.The ring segment upper surface is provided with one and the matched ring in gasket lower face
Shape protrusion 23, the annular protrusion realize sealing with gasket cooperation.
In one preferred embodiment of the utility model, the ontology lower end is provided with intake tunnel 11, the ring segment it is straight
