Abstract
The invention discloses a kind of New-type safety valves, including valve body, valve chamber, pressure relief opening, import, safety valve loop bar, safety lever, bottom plate, valve chamber is offered in the valve body, the valve body right side central offers pressure relief opening, the body base offers import, the safety lever is mounted on inside safety valve rod set, is welded with bottom plate at the top of the valve chamber, the safety valve rod set screw top is connected on bottom plate.The configuration of the present invention is simple, design is reasonable, ingenious in design using spring, idler wheel and wirerope is limited on safety lever top to the safety valve rod set end without this body length by spring, and when pressure adds safety lever self gravity greater than spring force, safety lever, which is taken in automatically in safety valve rod set, makes import carry out pressure release together with pressure relief opening.
Description
Technical field
The present invention relates to a kind of valve technology field more particularly to a kind of New-type safety valves.
Background technique
Current safety valve generally comprises valve body, and valve body is provided with safety lever, safety spring, pressure relief opening, import, import
Connect entrance safety valve beyond the Great Wall, when the pressure of fluid in pipeline is sufficiently large, so that it may overcome spring pressure by safety valve
Plug is washed open, so that extra fluid is discharged from pressure relief opening.And the safe valve plug of this safety valve is easy aging, is difficult to reach after aging
To scheduled effect.
Summary of the invention
The purpose of the present invention is to provide a kind of New-type safety valves, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme:
A kind of New-type safety valve, including valve body, valve chamber, pressure relief opening, import, safety valve rod set, safety lever, bottom plate, institute
It states and offers valve chamber in valve body, the valve body right side central offers pressure relief opening, and the body base offers import, the peace
Full valve bar is mounted on inside safety valve rod set, and bottom plate, the safety valve rod set screw top connection are welded at the top of the valve chamber
On bottom plate.
Preferred: the New-type safety valve further includes spring, sleeve, pulley and wirerope, and the spring top is bonded in
Bottom base plate, the spring bottom are bonded in sleeve, and the sleeve bottom is equipped with pulley, the wirerope one by shaft
End is fixed on bottom base plate, and the other end bypasses pulley connection safety valve bar bottom inside.
Preferred: the valve body, safety valve rod set, safety lever, bottom plate and sleeve are all made of 304 stainless steel material systems
Make.
The beneficial effects of the present invention are: the configuration of the present invention is simple, design rationally, utilizes spring, idler wheel and wirerope
Ingenious in design is limited on safety lever top to the safety valve rod set end without this body length by spring, when pressure is greater than bullet
Safety lever, which is taken in automatically in safety valve rod set, when spring force adds safety lever self gravity lets out import together with pressure relief opening
Pressure.

Specific embodiment
The present invention is further elaborated in the following with reference to the drawings and specific embodiments:
As shown in Figure 1-3, a kind of New-type safety valve, including valve body 1, valve chamber 2, pressure relief opening 3, import 4, safety valve rod set 5,
Safety lever 6, bottom plate 7 offer valve chamber 2 in the valve body 1, and 1 right side central of valve body offers pressure relief opening 3, the valve
1 bottom of body offers import 4, and the safety lever 6 is mounted on inside safety valve rod set 5, is welded with bottom plate at the top of the valve chamber 2
7,5 screw top of safety valve rod set is connected on bottom plate 7.The New-type safety valve further includes spring 8, sleeve 9, pulley 10
With wirerope 11,7 bottom of bottom plate is bonded at the top of the spring 8,8 bottom of spring is bonded in sleeve 9, the sleeve 9
Bottom is equipped with pulley 10 by shaft, and described 11 one end of wirerope is fixed on 7 bottom of bottom plate, and the other end is around the connection of pulley 10
6 bottom inside of safety lever.The valve body 1, safety valve rod set 5, safety lever 6, bottom plate 7 and sleeve 9 are all made of 304 stainless steels
Material production.
Working principle of the present invention: the import 4 of safety valve is mounted in the outlet of pipeline, is generated when the fluid in pipeline
When pressure is more than 8 elastic force of spring and 6 self gravity of safety lever, safety lever 6 is entered in safety valve rod set 5 by jack-up, makes
Tube fluid flows into pressure relief opening 3 by import 4 and carries out row pressure, and sleeve 9 is jacked up band movable pulley 10 due to 8 elastic force of spring after pressure release
It moves down, being elongated on the left of wirerope 11 causes the wirerope 11 on 10 right side of pulley to shorten to make 6 pull-up of safety lever
Safety lever 6 skids off block input port 4 again out of safety valve rod set 5 and guarantees tube fluid pressure.
The configuration of the present invention is simple, design rationally, utilize the ingenious in design by safety lever of spring, idler wheel and wirerope
The safety valve rod set end is pushed up without the limitation by this body length of spring, adds safety lever itself when pressure is greater than spring force
Safety lever, which is taken in automatically in safety valve rod set, when gravity makes import carry out pressure release together with pressure relief opening.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter from
From the point of view of which point, the embodiments should be taken as exemplary, therefore the same variation in equivalency range is all included in the present invention
In range.
