Description
Technical field
The utility model relates to pressure regulator technical field, specifically a kind of pressure regulator self-closing component.
Background technique
As shown in Figure 5 and Figure 6, design has the rectangular of 4 installations to slit in the improved pressure regulator self-closing component of applicant
Mouth 1.5 also complies with requirement in installation and use process, but there is also a shortcomings: after assembling, production has rectangular gap
End face and voltage regulator body between be sealed by gasket；When according to standard method normal mounting pressure regulator, it is not present
Problem；And valve seat is pushed into valve when liquefied gas user is not according to standard group mounted voltage regulator, such as through rotation voltage regulator body
In body, the gasket in voltage regulator body is easy to be scratched by the gap of seat bottom portion, increases security risk.
Utility model content
The purpose of the utility model is to overcome the deficiencies in above-mentioned background technique, provide a kind of pressure regulator of hexagonal hole formula certainly
Enclosed component, the component should have the characteristics that structure is simple, function is reliable, quality is stable, easy for installation.
The technical solution of the utility model is:
A kind of pressure regulator self-closing component of hexagonal hole formula, it is characterised in that: the structure includes valve seat, can be along in valve seat
Chamber plays mandril in axial sliding, is arranged in the annular groove for playing mandril outer wall and the spool cushion rubber of sealing surface of seat cooperation, setting
With the exterior seal ring of valve body cooperation, pushing tow bullet mandril so that the spool cushion rubber and sealing surface of seat of bullet mandril close on valve seat outer wall
The spring of conjunction；The bottom of the valve base cavity is Hexagon hole, and the outer wall of valve seat is equipped with external screw thread.
It is equipped with the venting channels for axially extending to bottom end face inside the bullet mandril, plays mandril outer wall and is equipped with connection ventilation
Several ventholes in channel.
The top of the valve base inner wall is equipped with the baffle ring for stopping spring, and the top for playing mandril is equipped with boss, the both ends of spring
It presses against between baffle ring and boss.
The sealing ring includes O-ring seal and sealed nylon circle.
The spring is tower spring.
The beneficial effects of the utility model are:
1, the utility model maintains original function of self closing, while eliminating gap and by seat design at Hexagon hole
Structure, have product structure is simple, (hexagonal hole is made of forging technology) easy to process, does not increase part difficulty of processing
Advantage also reduces the process of subsequent assembly；
Even if 2, user takes the mounting means of mistake, the wind of gap damage pressure regulator gasket will not occur
Danger improves the quality of product and using safety index, thoroughly avoids security risk, safety with higher and reliable
Property；
3, the utility model can treat as semifinished tube as an individual component (needing to be fitted into voltage-regulating transformer valve body)
Reason, if any the part of neglected loading, can also be easy to verify, reliable performance and stability is good.

Specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
As shown in Figure 1, a kind of pressure regulator self-closing component of hexagonal hole formula, including valve seat 1, bullet mandril 2, spring 4.
Be equipped with inside the valve seat axially through inner cavity, the top of valve base inner wall is equipped with baffle ring 1.1, in valve base inner wall
Portion is equipped with sealing surface 1.2, and the bottom of valve base cavity is Hexagon hole 1.3 (being located at below sealing surface), and valve seat outer wall is equipped with outer spiral shell
Line 1.4 and it is also equipped with O-ring seal 5 and sealed nylon circle 6.In Fig. 1, the top of the valve seat is air inlet, and bottom is
Gas outlet.Hexagon hole need to be used when valve seat is fitted into the valve body of pressure regulator.
The bullet mandril is axially slidably located in valve base cavity, is played mandril outer wall and is equipped with annular groove 2.1, spool glue
Circle 3 is mounted in annular groove for cooperating sealing surface of seat to realize sealing, and the top for playing mandril is equipped with boss 2.2, is played in mandril
Portion is equipped with the venting channels 2.3 for axially extending to bottom end face, plays the venthole that mandril outer wall is equipped with several connection venting channels
2.4。
The spring is arranged in valve seat, by pushing tow bullet mandril so that the spool cushion rubber for playing mandril is closed with sealing surface of seat
It closes, realize valve seat and plays the sealing between mandril.Tower can be used respectively against baffle ring and boss, spring in the both ends of the spring
Spring.
The utility model is the self-closing component of monoblock type, and valve seat is directly screwed into the valve of pressure regulator when producing pressure regulator
(use tools for alignment Hexagon hole rotary valve base) is fixed with bolt again in body 9, is equipped in valve body and to be cooperated with valve seat external screw thread
Internal screw thread can not only improve assembly efficiency, greatly improve production capacity, and assemble convenient for detection and external coordination, effectively improve
Product stability.
When using pressure regulator, with the screw-in of pressure regulator valve rod, valve seat is gradually opened so that sealing surface of seat and valve
Core rubber circle separates, and combustion gas enters from the venthole for playing mandril, enters pressure regulator by the gap between valve seat and bullet mandril.
Finally it should be noted that listed above is only specific embodiment of the utility model.Obviously, this is practical new
Type is not limited to above embodiments, can also there is many variations.Those skilled in the art can be from disclosed by the utility model
All deformations for directly exporting or associating in content, are considered as the protection scope of the utility model.
