Embodiment
Generally according to the present invention, the optimal feasible embodiment, and coordinate 1~Fig. 5 of accompanying drawing specifically
After bright, the understanding in order to increase to the present invention；
A kind of energy-saving precision pressure regulator valve of the present invention, with a body 1, the body 1 is from top to bottom
Valve seat 12, a base 13, which link, in a pressure regulating seat 11, one is constituted, and inside of valve seat 12 has in this
One passage 123, the one weighing apparatus pressure regulation straight-bar 122 of pressure passageway 124 and one, and valve seat 12 and the pressure regulation in this
Seat 11 between sandwiched have piston 1211 one balance diaphragm 121, and the pressure regulating seat 11 have lead in it
One spout hole 113 in portion, and have a pressure ports 133, one of voltage supply power P guiding inside the base 13
The overflow pipe 132 of base throttle orifice 134 and one, and it is folded between valve seat in this 12 main film
131, and the outer layer of foregoing piston 1211 and pressure regulation straight-bar 122 is coated by quality of rubber materials
Composition, can quickly reach the effect of seal pressure, also can be replaced flexible similar material, and
It is not limited to this.
And the passage 123 is connected with pressure ports 133, input pressure P can be guided to the pressure regulation straight-bar
122, enable the vertical displacement of pressure regulation straight-bar 122 and the mutual contact of piston 1211, use complete pass
The spout hole 113 is closed, the body 1 can be allowed under no pressure P overflow situations, remains to continue to adjust pressure
P, exports high-precision pressure purpose.
Refer to again such as Fig. 1~Fig. 4, the pressure regulating seat 11 includes a main spring 112 and a knob 111,
The main spring 112 can be manipulated in the pressure regulating seat 11 by the knob 111 outside the pressure regulating seat 11
Adjustment, and this contact of main spring 112 balance diaphragm 121, and by the foregoing pressure being input into body 1
Power P is guided, and can be formed with a balance pressure Pt.
And described pressure P is inputted to body 1 by outside adjustment flow, primary side will be produced when input
Pressure P1, and secondary pressure P2 will be then produced when output；
As a lateral pressure P1 via the flow direction of pressure ports 133 inside base 13 located at valve seat 12 in this
Interior passage 123, the wherein base 13 have a base throttle orifice 134, can reduce unnecessary primary side
Pressure P1 flows into pressure regulation straight-bar 122, and is exhausted in subsequently through the spout hole 113.
And the passage 123 guides a lateral pressure P1 to the set part of pressure regulation straight-bar 122, the balance film
Piece 121 is pushed down on by the main spring 112 and forms a balance pressure Pt, the balance diaphragm now
The piston 1211 and the mutual contact of pressure regulation straight-bar 122 in 121 centers, therefore then edge should by a lateral pressure P1
Passage 123 persistently circulates, and promotes the main film 131 thereby to form secondary pressure P2, and leads to
Cross overflow pipe 132 and flow to ttom of pipe, promote the contact main film 131 of overflow pipe 132, and closed main film 131
On central aperture 1311, and in being subsequently circulated in the weighing apparatus pressure passageway 124 of valve seat 12 in this, and then push away
The balance diaphragm 121 is moved, by the pushed home of main spring 122, pressure regulation straight-bar 122 such as Fig. 1~Fig. 2 must be made
Pressure regulation straight-bar 122 its lateral pressure P1 limitation can not be circulated, thereby enable secondary pressure P2
Form voltage stabilizing state.
Furthermore, in balance diaphragm 121 on, secondary pressure P2 area * secondary pressures P2：It is (flat
Weigh pressure Pt area * balances pressure Pt), if when more than both Bi Zhi≤5, base throttle orifice 134
Below Ф 0.5mm can be decreased to, and be improved secondary pressure P2 voltage stabilizing state；Therefore understand to work as
When secondary pressure P2 becomes big, main spring 112 can be pushed open in real time, many overbottom pressure are discharged through the spout hole 113
Power P；If when secondary pressure P2 changes are small, the main spring 112 can in real time promote the balance diaphragm 121,
Balance pressure Pt is allowed to be able to promote the main film 131 to improve secondary pressure P2, until voltage stabilizing is
Only.
However, the foregoing variation about secondary pressure P2 of correspondence, when its lateral pressure P1 becomes big,
It is in the state that a contact is closed that the pressure regulation straight-bar 122, which can then be withstood, so secondary pressure P2 also will not
Change；And when a lateral pressure P1 becomes small, its strength for withstanding the pressure regulation straight-bar 122 is also phase
To diminish, but because foregoing secondary pressure P2 area * secondary pressures P2 proportion is higher than
Balance pressure Pt area * balance pressure Pt, so the main spring 112 is had to slowly promote this to put down
Weigh diaphragm 121, opens pressure regulation straight-bar 122, allows balance pressure Pt slightly to be increased, and then promote the master
Diaphragm 131 improves secondary pressure P2, allows the secondary pressure P2 to be able to push the balance diaphragm 121 open,
Balance pressure Pt is allowed to reduce again, until secondary pressure P2 is returned to original pressure state and is gradually
Only.
However, referring to again such as Fig. 5, its structure designed is held is related to patent of invention as foregoing
Structure described in M513296 contents, but structure of the present invention in base 13 by a lateral pressure P1 inputting
Unidirectionally pass through for it to secondary pressure P2, and middle valve seat 12 is then to two-way circulate, but pass through middle valve seat
12 coordinate the aperture in the center of main film 131 to reach switching motion, and then correspondingly maintain its to balance pressure
Pt, allows base 13 in also being to two-way circulate in actual operation, therefore in this simple declaration both structure
The deviation of operation principles, makes it be more easy to be understood.
In summary, energy-saving precision pressure regulator valve of the present invention, passes through the pressure ports 133 set by inside
With passage 123, allow input pressure P by flowing to pressure regulation straight-bar 122, coordinate the balance diaphragm 121
Produced balance pressure Pt, can cooperate with the secondary pressure P2 and main film 131 of circulation,
Allow the inside of body 1 to maintain balance, and allow pressure P air consumption can under conditions of without overflow,
Progress increases secondary pressure P2 or decompression, the consumed pressure energy is reached improved purpose.
Finally, it is necessary to illustrate again, present invention constituent components disclosed in previous embodiment
And its shape is by way of example only, not for limiting the scope of the present invention, moreover, reading this
After the content of invention, relevant technical staff in the field can make various changes or modification to the present invention,
These equivalent form of values equally fall into the application appended claims limited range.
