Embodiment 1
This utility model provides the pressure maintaining valve of a kind of improvement, including: valve body 1, on the valve seat 2 bottom it
Being provided with fluid inlet 4, its sidepiece is provided with fluid issuing 5；Valve gap 3, seals with described valve body 1
Forming chamber, described valve gap includes that valve gap main body 9 and gland 10, described gland 10 are " several " font
Structure, described gland 10 is sealed in described valve gap main body 9；Fixed mount, is fixed in described chamber,
Described chamber is divided into epicoele 6 and cavity of resorption 7；Flap assembly, hangs in the chamber by fixed mount, and one
End is positioned in epicoele 6 through described fixed mount, and the other end stretches into the described fluid being positioned in cavity of resorption 7 and enters
In mouthfuls 4, and form fluid passage, when described flap assembly moves upward, institute with the sidewall of valve seat 2
Opening 18 size stating fluid passage reduces.When the fluid flow entering valve body 1 is excessive, described valve
Lobe assembly moves upward under the promotion of fluid, and then reduction is even switched off fluid passage, thus prevents
Overpressure fluid is excessively entering in described valve body 1, damages the pipeline being connected with fluid issuing 5.
As preferably your embodiment, the described pressure maintaining valve that this utility model provides also includes spring
8, its one end acts against on described valve gap 3, and the other end connects described flap assembly and is positioned at described epicoele 6
In one end, to the downward pretightning force that described flap assembly is certain.
When flap assembly described in fluid flow crosses ambassador rises, by the pretightning force of described spring 8,
Flap assembly can be made to increase gently, slowly reduce described fluid passage, make the flow in valve body 1 protect
Keep steady fixed, it is to avoid flap assembly causes valve body 1 inner stream flow drastically to change due to strenuous exercise, thus
Guarantee the stability of valve body 1 internal flow flow.
Specifically, when fluid is in condition of normal pressure, described flap assembly the most described valve seat 2 sidewall
Position is fixed, and the size of the most described fluid passage does not changes, and fluid can be with stable flow
Enter in the middle of described valve body 1.When fluid is in pressure, described flap assembly is in overpressure fluid
With under the common effect of described spring 8, the most described valve seat 2 sidewall is risen, the most described fluid
Passage will reduce, but due to the effect of spring 8 so that described valve board assembly can gently rise,
Although now the flow velocity of fluid adds, but owing to the area of fluid passage reduces, so during unit
The interior fluid total volume entered within valve body 1 is constant, thus plays a protective role.When fluid stream
When amount increases further, hypervelocity fluid will be greater than described spring 8 to institute to the thrust of described flap assembly
Stating the propulsive thrust of flap assembly, the most described flap assembly will block described valve seat 2 sidewall, thus close
Close described fluid passage, prevent fluid from entering described valve body 1 internal, to valve body 1 and with valve body 1
The pipeline being connected causes damage.
As preferred embodiment, the described gland 10 that the present embodiment provides can seal up and downly
On the top of described valve gap main body 9；The top of described spring 8 acts against the bottom surface of described gland 10
On.Adjusting described gland 10 makes its most described valve gap 3 move up and down, it is possible to adjust described spring 8
Pretightning force, and then adjust when described flap assembly meet with overpressure fluid time rise be difficult to degree.
Specifically, when the anti-pressure ability of the pipeline that described valve body 1 connects is higher, described gland is regulated
10 the most described valve gap main bodys 9 move downward, and the most described spring 8 is compacted, enter in valve body 1
Fluid pressure of a relatively high.When the resistance to compression degree of the pipeline that described valve body 1 connects is relatively low, regulation
Described gland 10 the most described valve gap main body 9 moves upward, and the pretightning force of the most described spring 8 is less,
When overpressure fluid acts on described flap assembly, described flap assembly reacts rapidly, reduces and even closes
Close described fluid passage.
As preferred embodiment, described valve seat 2 forms the position of described fluid inlet 4 and is provided with
The valve seat tilting section 12 that the vertical section of valve seat 11 and section vertical with described valve seat 11 are connected, described valve seat inclines
Tiltedly section 12 is positioned at the top of the vertical section of described valve seat 11, and described valve seat tilting section 12 is towards described fluid
Tilt at the axle center of import 4；Described flap assembly and described valve seat 2 cooperatively form described fluid passage
The flap tilting section 14 that position is provided with the vertical section of flap 13 and section vertical with described flap 13 is connected,
Described flap tilting section 14 is positioned at the top of the vertical section of described flap 13, described flap vertical section 13 He
The vertical section of described valve seat 11 the most just to and parallel, described flap tilt
Section 14 with described valve seat tilting section 12 the most just to and parallel.Described
Fluid passage includes vertical direct current section 15 and the tilting section 16 connected with described direct current section 15, described
Direct current section 15 is positioned at the lower section of tilting section 16, and described tilting section 16 is connected from described direct current section 15
Position towards described flap assembly axis direction tilt.Fluid initially enters in described vertical section,
Enter after tilting section 16 fluid due to by resistance, flow velocity and the impact strength of valve body 1 sidewall will be subtracted
Little, thus contribute to the protection to valve body 1 self.
As preferred embodiment, the described fixed mount that this utility model provides is fixed plate 17, institute
Stating fixed plate 17 across in the cavity, its two ends are sealedly connected on described valve gap 3 respectively, institute
The middle part stating fixed plate 17 has opening 18, and described flap assembly is by being overlapped on described opening 18
Two ends and hang in the cavity, described flap assembly one end is stretched on described through described opening 18
In chamber 6, the other end of described flap assembly stretches in described cavity of resorption 7 through described opening 18.
As preferred embodiment, the described flap assembly that this utility model provides includes: ledge
19, it is positioned in described epicoele 6, and is overlapped on the two ends of described opening 18；Connecting rod 20；It is fixed on institute
State the lower section of ledge 19, be positioned in described cavity of resorption 7 movably through described opening 18；Flap
21, be connected to the lower end of described connecting rod 20, and stretch in described fluid inlet 4 with described valve seat 2 shape
Become described fluid passage.Preferably, the described ledge 19 that this utility model provides is inverted T-shaped structure,
Its horizontal component is overlapped on the two ends of described opening 18, and its vertical portion connects the bottom of spring 8.
Specifically, as it is shown in figure 1, the bottom of described ledge 19 is placed on described fixed plate 17
Top, the horizontal component of described ledge 19 is arranged on the lower end of described spring 8, when described flap group
When part moves upward, described spring 8, by the active force downward to described ledge 19, makes described connecting rod
20 mild risings, the vertical portion of described ledge 19 can move up and down along described opening 18.
As preferred embodiment, described connecting rod 20 lower end that this utility model provides offers connection
Chamber, described flap 21 top forms the projection 23 corresponding with described connection chamber, described connection chamber with
Described projection 23 is attached by screw thread.Described projection 23 can be transported up and down at described connection intracavity
Move, and then the size of described fluid passage can be regulated, thus regulate the flow entering described valve body 1.
