Provided with four spout holes on the taper surface of valve rod base, four spout holes are according to the center line of valve rod base in circumference
Direction is evenly distributed.
The outer surface of the bonnet is provided with clamping part and square fastening notch；The radially row of being additionally provided with bonnet
Gas port；Fastened in square and lead seal hole is provided with the vertical plane of notch.
The open notch that the outer end of the adjusting screw is radially provided with；In the outer end of adjusting screw along footpath
Pin-and-hole is additionally provided with to direction.
The spring uses combined type disc spring.
The present invention has the advantages and positive effects of：Because the present invention uses above-mentioned technology to have advantages below：
1st, valve body：It is subject by the pressure of protection system, so valve body should have enough strength and stiffness, does not allow
Now deform or leak.Unilateral bleed outlet on conventional valve body is changed to drainage orientation discharge, reduces valve body because unbalance stress is produced
Deformation.Intrinsic safety full valve makees valve body from high strength steel, it is ensured that sealing, No leakage.
2nd, valve core case：Valve core case is designed to dismountable structure type.Demountable structure, it is possible to reduce because of valve body deformation,
Produce on the sealed influence of valve core case, the deformation of valve core case is to cause the main cause of safety valve escape.Demountable, just
In processing and manufacturing, it is easy to which maintenance is changed, cost-effective, and can improve the sealing of safety valve, it is ensured that high pressure operation can
By property.Multiple pod apertures are provided with valve core case, this feature can meet after valve element is opened and discharge as early as possible, and swollen using liquid
Swollen recoil strength is rapidly reached valve element to open state entirely.Improve the sensitivity of safety valve.
3rd, valve element, valve rod：Valve element and valve core case constitute sealing surface together, sealing surface side directly bear medium pressure,
Temperature etc., its structure design directly influences the reliability of safety valve.
The design of valve element employs ball face sealing structure, and spherical seal surface has good sealing and self-cleaning, structure
Simply, can be by being automatically reset the characteristics of itself, it is ensured that sealing when deviation or mild wear occur for sealing surface.Valve element leans on bullet
The pressure difference of spring force and pressure medium is opened with returning seat to realize.
4th, spring：Select rigidity big, with rigidity is become, axially occupied little space, the combined type disc spring generation of compact conformation
For traditional cylindrical spring, it is used to overcome pressure medium as mechanical load, is applicable load range extensively, be more suitable for high pressure peace
The structure of full valve, safety valve is opened and closed in time, and valve element is not likely to produce frequency modulation and flutter phenomenon.The active force of dish spring is by valve rod
Seat passes to valve element, forms initial sealing.When valve element is acted, valve rod is moved up and down along adjusting screw pilot hole, therefore valve rod
Important role.When spring force passes to valve element, valve element lifting surface area is bigger, and stress point distribution is more uniform, seals more reliable,
This structure employs ball face sealing, and the structure of plane stress improves sealed reliability.Increase valve element positioning sleeve, it is ensured that valve element
The centering of closure shift position is opened, the phenomenon that valve element is glanced off with valve seat will not be produced, sealing is improved.Valve element is adopted
With the hard alloy material of Wear resistant anti-high pressure, service life height.
In summary, this structure is a kind of pressure-adjustable liquid collecting type overflow manner, i.e. the overflow of liquid is will be conventional any
Discharge, drainage centralized collection orientation off-load, improves the working environment at scene, while resource is also saved, this safety valve
In the range of certain pressure, initial tension of spring is changed by adjusting screw, makes Opening pressure that there is adjustability, and the present invention is also
It is compact with simple in construction, convenient disassembly, the advantages of service life is long.
