Specific embodiment
The present invention is a kind of energy-saving type vacuum precise pressure regulating valve, next will be carried out in conjunction with embodiment of the attached drawing to invention detailed
Describe in detail it is bright, with help understand the present invention.
The energy-saving type vacuum precise pressure regulating valve has an ontology (1), and the ontology (1) is by valve seat in a main valve seat (2), one
(3) and a pressure regulator (4) it, is sequentially constituted from the bottom to top, which has one for a pressure fluid (P) circulation
Input terminal (21) and an output end (22) and the main valve doorway (24) being made of an overflow pipe (23), and it is excessive at this
The top of flow tube (23) is additionally provided with a main film (25), and middle valve seat (3) then has the straight-bar being made of a pressure regulation straight-bar (31)
Valve port (33) and a pressure regulation subaisle (51), and the top of the pressure regulation straight-bar (31) is additionally provided with a balance diaphragm (34)；And
There is the pressure regulator (4) main spring (41), a knob (42) and a leakproof seal part (43), the main spring (41) to be set to
In the pressure regulator (4), the knob (42) of the pressure regulator (4) outside is adjusted by manipulation, main spring (41) contact balance can be made
Diaphragm (34), and leakproof seal part (43) are set on the top of the main spring (41), to the pressure for preventing ontology (1) internal
Fluid (P) thus overflows.
Several channels are additionally provided in the ontology (1), are respectively as follows: pressure ports (5), pressure regulation subaisle (51), weighing apparatus pressure passageway
(52) and plasmas channel (53).Wherein pressure ports (5) by main valve seat (2) are connected to middle valve seat (3) and to straight-bar valve ports
(33), and a throttle orifice (26) are equipped with；Pressure regulation subaisle (51) is then connected to position set by main film (25) as the pressure ports (5)
It sets；Weighing apparatus pressure passageway (52) is connected to main film (25) and output end (22) by pressure regulator (4)；An and plasmas channel (53)
By the lateral margin for being connected to middle valve seat (3) above pressure regulation straight-bar (31).
Cooperate pressure regulator (4) adjustment main spring (41) through pressure ports (5) by input terminal (21) by pressure fluid (P)
Passage balance diaphragm (34), makes pressure fluid (P) that can continue to be circulated to pressure regulation subaisle (51), whereby elapses main film (25)
At the equilibrium state of air pressure, further using weighing apparatus pressure passageway (52) output to output end (22), make ontology (1) without sucking atmosphere
Pressure remains to accurate adjustment pressure fluid (P).
Fig. 1~1B is please referred to again, and there are aforementioned pressure fluid (P) a variety of pressure to input wherein there is a vacuum source (P1)
(21), pressure ports (5) and interior draw of pressure regulation subaisle (51) is held to be formed；One vacuum suck end (P2), is formed in output end
(22), it weighs pressure passageway (52) and the overflow pipe (23) is interior；One balance pressure (Pt), by ontology (1) vacuum source (P1) with
Vacuum suck end (P2) mutually balance is formed.
Pressure ports (5) absorption forms vacuum source (P1) with input terminal (21), when preparing state, the vacuum source
(P1) it only terminates at straight-bar valve port (33), therefore vacuum suck end (P2) is equal to balance pressure (Pt) equal to 0, and the vacuum source
(P1) less than 0；
At this point, balance diaphragm (34) is not affected by the manipulation adjustment of the knob (42) on pressure regulator (4) main spring (41), the balance
Piston (32) set by below diaphragm (34) is not yet supported with the pressure regulation straight-bar (31), the overflow hole (311) in the piston (32) then with
The plasmas channel (53) interlinks；And the main valve doorway (24) of overflow pipe (23) is in closed state.
Figure is please referred to againAnd Fig. 4, for the schematic diagram that the present invention is in running order, vacuum at this time is inhaled
Enter end (P2) less than 0, and vacuum source (P1) is less than balance pressure (Pt) and is less than vacuum suck end (P2)；Turned by pressure regulator (4)
Dynamic knob (42) allow main spring (41) to press downwards, make to balance diaphragm (34) promotion piston (32), and close overflow hole (311),
And push pressure regulation straight-bar (31) downwards open straight-bar valve port (33), vacuum source (P1) at this time then can by throttle orifice (26) with
Pressure ports (5) enter pressure regulation subaisle (51), and balance pressure (Pt) is formed below main film (25)；And vacuum suck
The vacuum pressure for holding (P2) to be formed can elapse main film (25) by weighing apparatus pressure passageway (52) to main film (25) top；Throttle orifice
(26) effect can reduce the inhalation flow of vacuum source (P1), be unlikely to the variation for balancing pressure (Pt) too acutely, main film
(25) pressure balance can also smoothly be reached, when forming the working condition of balance, straight-bar valve port (33) can close upwards, and
Lower section main valve (24) is open state, and vacuum source (P1) enters in main valve body (2) whereby, forms output pressure, recirculation is extremely
Vacuum suck end (P2).
Figure is please referred to againIts schematic diagram that pressure release state is in for the present invention, vacuum source (P1) at this time are equal to
0, and under normal pressure release state, the main spring (41) in pressure regulator (4) can allow straight-bar valve port (33) to open, and close the overflow
Hole (311), and the air of vacuum source (P1) enters under main film (25) through straight-bar valve port (33) and pressure regulation subaisle (51)
Square destruction of balance pressure (Pt), and push main film (25) open, it is pressed by hollow hole (251) set by main film (25) center and weighing apparatus
Channel (52) enters to vacuum suck end (P2) and destroys output pressure, and main valve doorway (24) are in closed state；
In addition, when ontology (1) internal balance pressure (Pt) and vacuum suck end (P2) pressure difference are not big enough, internal main film
(25) it is easy to produce clamping, can not be successfully pressure release, therefore be equipped with a packing (231) in overflow pipe (23) bottom end, it can be for air list
To packing (231) are pushed open, using the external diameter surface of overflow pipe (23), the center for enabling air to smoothly flow into overflow pipe (23) is straight
Hole, then so that the air of vacuum source (P1) is entered to vacuum suck end (P2) by weighing apparatus pressure passageway (52) and destroy output pressure.
The area at vacuum suck end (P2) suffered by above-mentioned balance diaphragm (34) multiplied by the vacuum suck end (P2) resulting value
When being more than or equal to 5 or more multiplied by the ratio between resulting value of the balance pressure (Pt) with the area of balance pressure (Pt), throttle orifice (26)
Diameter can be 0.5 hereinafter, the stable state of vacuum suck end (P2) pressure can be effectively improved.
In conclusion energy-saving type vacuum precise pressure regulating valve of the invention can have a clear understanding of this by different working conditions
The internal each channel of body (1), cooperates main valve doorway (24) and straight-bar valve port (33), can be without persistently sucking atmospheric pressure flow
In the case where, the Vacuum Balance in ontology (1) is maintained, and remain to the accurate adjustment for carrying out pressure by pressure regulator (4), makes its section
The benefit for saving the vacuum source energy has practical usability.
Structure, feature and effect of the invention, the above institute is described in detail according to diagrammatically shown embodiment above
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
Think made change or equivalent example modified to equivalent change, when not going beyond the spirit of the description and the drawings,
It should all be within the scope of the present invention.
