Description
Technical field
It the utility model is related to a kind of safety valve class technical field, especially a kind of safety using new highly dense packing
Valve.
Background technology
Safety valve is the safety device of pressure piping, is typically mounted on closed system equipment or pipeline and protects system
System safety, when the pressure inside the equipment of closed system or pipeline exceedes setting value, safety valve automatically turns on release pressure,
Ensure that the pressure medium in equipment or in pipeline in specified value, prevents security incident, however, common safety valve
Sealing generally uses valve seat overcoat sealing ring, is bonded with the plane of sealing ring with plane on the exhalant canal of valve body, employing mode
For flat seal, contact area is big, and the hidden danger leaked after sealing is high, although there is the flexible of sealing ring to be used as fine setting, work as Jie
When solid particles in matter rest on the contact plane of sealing, safety valve just has the phenomenon of leakage.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of using new highly dense packing
Safety valve, including valve body, highly dense packing, spool, spring, adjusting screw, set valve storehouse in valve body, and the passage of valve storehouse and lower end connects
Logical, passage upper end sets the highly dense packing that material synthesizes as metal with high density composite material, the semicircle sphere of highly dense packing lower end
Suitable for reading with passage is edge seal state, and the platform upper end of highly dense packing upper end sets spool, under the blind hole and spring in spool
End cap connects, and spring upper end sets adjusting screw, and adjusting screw is spirally connected with valve storehouse interior internal thread suitable for reading, the utility model sealing structure
Simply, space is compacter, density of material is high, wear-resistant, so as to reduce security risk, improves performance and service life,
Leakproofness is strong, and safety coefficient is high.
To reach above-mentioned purpose, the technical solution of the utility model is：A kind of safety valve using new highly dense packing, bag
Valve body, highly dense packing, spool, spring, adjusting screw are included, valve storehouse is set in the valve body, the valve storehouse is connected with the passage of lower end,
The passage upper end sets highly dense packing, and the semicircle sphere of the highly dense packing lower end and the suitable for reading of passage are edge seal state,
The platform upper end of highly dense packing upper end sets spool, and the blind hole in the spool is socketed with lower spring end, and the spring upper end sets tune
Screw is saved, the adjusting screw is spirally connected with valve storehouse interior internal thread suitable for reading.
Further set, the high sealing mat material matter synthesizes for metal with high density composite material.
Further set, the semicircle sphere diameter of the highly dense packing is more than channel diameter.
Further set, the semicircle sphere diameter of the highly dense packing is less than valve storehouse diameter.
Further set, the upper end of the spring props up adjusting screw, lower end props up spool, and the spool props up high sealing
The upper transverse plane of pad.
Further set, diameter is gradually reduced when the passage extends at lower ending opening to valve inner.
The beneficial effects of the utility model：The utility model sealing structure is simple, space is compacter, density of material is high,
It is wear-resistant, so as to reduce security risk, performance and service life are improved, leakproofness is strong, and safety coefficient is high.

Embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
As shown in FIG. 1 to 3, a kind of safety valve using new highly dense packing, including valve body 1, highly dense packing 2, spool
3rd, spring 4, adjusting screw 5, set valve storehouse 101 in the valve body 1, and the valve storehouse 101 is connected with the passage 102 of lower end, described logical
102 upper end of road sets highly dense packing 2, and the semicircle sphere 201 of highly dense 2 lower end of packing and the suitable for reading of passage 102 are edge seal
State, it is a coils sealing to make highly dense packing 2 and the suitable for reading of passage 102, changes conventional flat seal mode, carries significantly
High sealing performance and the hidden danger for reducing leakage, the platform upper end of highly dense 2 upper end of packing set spool 3, the blind hole in the spool 3 with
4 lower end of spring is socketed, and 4 upper end of spring sets adjusting screw 5, the adjusting screw 5 and the interior internal thread spiral shell suitable for reading of valve storehouse 101
Connect, the utility model sealing structure is simple, space is compacter, density of material is high, wear-resistant, so as to reduce security risk, carries
High performance and service life, leakproofness is strong, and safety coefficient is high.
2 material of highly dense packing synthesizes for metal with high density composite material, and sealing structure is simple, space is more stepped up
Gather, density of material height is more wear-resistant, raising performance and service life.
201 diameter of semicircle sphere of the highly dense packing 2 is more than 102 diameter of passage.
