It is equipped with lines (not labeled), which is used to improve feel when user's operation, prevents user when controlling the rotation of operating parts 60
It skids；Operating parts 60 is additionally provided with mark (not shown) on the end face far from 10 one end of valve body, which is used to indicate safety valve
100 information, such as indicate pressure fixing value, the rotation direction of safety valve 100 of safety valve 100.
In present embodiment, operating parts 60 is knob, and user controls operating parts 60 by the lines on operating parts 60 and rotates.
It is appreciated that in other implementations, operating parts 60 can also use the other kinds of operating parts such as handle.
In present embodiment, third protrusion 61 is generally circular.It is the present invention also referring to Figure 14 to Figure 15, Figure 14
The structural schematic diagram of operating parts 60a in third embodiment, Figure 15 are the structure at another visual angle of operating parts 60a shown in Figure 14
Schematic diagram, in present embodiment, third protrusion 61 is fillet hexagon.It is appreciated that in other implementations, third is convex
Other polygonal shapes such as round rectangle can also be used by playing 61, can also use other shapes such as star, lobed.
The installation process of safety valve 100 is briefly described below：
One end of elastic component 50 is sheathed on the boss 64 on operating parts 60, the other end is held in seal receptacle 40, will seal
One end that seat 40 is provided with benchboard 43 is stretched into operating parts 60 so that benchboard 43 passes through operating parts 60 by the 4th groove 44
On the first protrusion 63, one end of the benchboard 43 on seal receptacle 40 is held in the first protrusion 63 on operating parts 60, seal receptacle
40 kept under the elastic force effect of elastic component 50 with the close connection of operating parts 60, to realize seal receptacle 40, elastic component 50 and
Being fastenedly connected between operating parts 60；
Sealing element 20 is fixedly connected on seal receptacle 40 close to one end of valve body 10, then by operating parts 60, elastic component 50 and
Seal receptacle 40 is arranged in fastener 30 so that the third protrusion 61 of operating parts 60 is fixed on baffle ring 33 and on fastener 30
Between two protrusions 35, and the first groove 42 on seal receptacle 40 is connected with the second protrusion 35 on fastener 30, with
Circumferentially rotating for limitation seal receptacle 40, it is tight between fastener 30 and seal receptacle 40, elastic component 50 and operating parts 60 to realize
It is solidly connected；
Finally fastener 30 is screwed in valve body 10 so that the end face of fastener 30 supports and compresses the end of sealing element 20
Being fixedly connected for fastener 30 and valve body 10 and sealing element 20 is realized, to complete the installation process of safety valve 100 in face.
The operation principle of lower safety valve 100 is briefly described below：
The fluid sealing relation part 20 in inner cavity 11 in valve body 10 is in direct contact, and fluid media (medium) is by pressure transmission to sealing element
At 20, one end of sealing element 20 by fluid media (medium) pressure, the other end by elastic component 50 elastic force, when the pressure of fluid media (medium) is small
In the elastic force suffered by sealing element 20, i.e., when the pressure of fluid media (medium) is less than 100 preset pressure value of safety valve, 20 quilt of sealing element
The extruding of elastic component 50 is fixed in valve body 10, and safety valve 100 is closed；When the pressure of fluid media (medium) is more than suffered by sealing element 20
When elastic force, the i.e. pressure of fluid media (medium) are higher than 100 preset pressure value of safety valve, sealing element 20 is open-top by fluid media (medium), valve body
Inner cavity 11 in 10 is mutually communicated with pressure relief opening 12, and fluid media (medium) is discharged by pressure relief opening 12, under the pressure of fluid media (medium)
Drop；When the pressure of fluid media (medium) is decreased below 100 preset pressure value of safety valve, bullet of the sealing element 20 in elastic component 50
The pressure of fluid media (medium) is overcome under force effect, inner cavity 11 is sealed, and inner cavity 11 and pressure relief opening 12 is mutually isolated, to complete
Pressure leak process.
The manual pressure leak process of 100 pressure of safety valve is briefly described below：
User's control operating parts 60 rotates, due to the first protrusion 63 in operating parts 60 and the benchboard 43 on seal receptacle 40
Contacted with each other with bevel-faced form, the first protrusion 63 supports benchboard 43, and due to seal receptacle 40 under the limitation of fastener 30 nothing
Method circumferentially rotates, and is merely able to stretch axially back and forth along it, and with the rotation of operating parts 60, the first protrusion in operating parts 60
63 support benchboard 43 in different positions so that benchboard 43 is raised/reduced, to realize that it is close that the rotation of operating parts 60 drives
The start process that envelope seat 40 moves forward and backward；When being moved to the direction far from valve body 10 when seal receptacle 40, sealing element 20 is in seal receptacle
It is detached with valve body 10 under 40 drive so that inner cavity 11 and pressure relief opening 12 in valve body 10 are mutually communicated, and safety valve 100 is outside
Fluid media (medium) is discharged, to complete manual pressure leak process.
One end of safety valve 100 provided by the invention, elastic component 50 is held in operating parts 60, and the other end is held in seal receptacle
40, with consistent installation site, simplify the cumbersome tune for needing the height for adjusting elastic component 50 that could regulate and control pressure value
Section process, is not only simple in structure, and easy for installation.In addition, safety valve 100 provided by the invention, can complete manual pressure release
Process further improves the pressure control performance of 100 fluid medium of safety valve, is with a wide range of applications.
The present invention also provides a kind of wall-hung boiler heating system using above-mentioned safety valve 100, safety valve 100 is set to wall hanging
It in furnace heating system, is used to prevent the hypertonia of the fluid media (medium) in wall-hung boiler heating system, ensures wall hanging furnace heating system
The safe operation of system and the safety of user of service.
Those skilled in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, made by embodiment of above
Appropriate change and variation is all intended to fall within the scope of the claimed invention.
