Description
Technical field
The present invention relates to a kind of control loop, in particular to a kind of equipment work voltage-adjustable control loop.
Background technique
The circuit that the pressure of pneumatic system is adjusted and is controlled is known as pressure control loop, pressure control loop be to
Every pneumatic equipment provides the pressure regulation circuit of gas source, also known as secondary pressure control loop.Mainly by water filter, subtract
Pressure valve, oil sprayer pneumatic three-major-items composition, but pressure control loop in the market is complex, price is relatively high, Given this
A kind of equipment work voltage-adjustable control loop.
Summary of the invention
Present invention solves the technical problem that being, using the operating pressure in overflow pressure reducing valve control hydraulic system, satisfaction is held
Requirement of the units to power or torque, keeps system whole or a certain partial pressure keeps constant or be no more than certain numerical value.
The present invention provide a kind of equipment work voltage-adjustable control loop include: pneumatic supply, air filter, overflow pressure reducing valve,
Pressure gauge, oil sprayer, wherein pneumatic supply 1 is connect with air filter by working line, when pneumatic supply by working line into
When entering filter, liquid water, the liquid oil droplet in compressed air are separated, and filter off the dust in air and solid is miscellaneous
Matter, the key for influencing filtering accuracy is filter core, can need to select different filter cores according to component below, is reached corresponding
Filtering accuracy.
Air filter is connect with overflow pressure reducing valve by working line, and overflow pressure reducing valve is the throttling action by air inlet
Decompression, the balanced action of power and the overflow of overflow hole act on pressure stabilizing on diaphragm；Adjustment spring can make output pressure certain
Change in range.
Overflow pressure reducing valve is connect with pressure gauge, oil sprayer by connecting line respectively, and is shown according to the degree of pressure gauge,
Device pressure size is adjusted in the spring being adjusted on overflow pressure reducing valve, and oil sprayer is a kind of special oiling device, works as pressure
Stream of compressed air is out-of-date, it nebulizes lubricating oil injection, and the component for needing to lubricate is flowed into compressed air, reaches lubrication
Purpose.
Overflow pressure reducing valve is inlet pressure to be reduced to the outlet pressure of a certain needs, and rely on medium itself by adjusting
Energy, so that outlet pressure is automatically kept stable valve.From the viewpoint of hydrodynamics, pressure reducing valve is that a local resistance can
With the restricting element of variation, i.e., by changing orifice size, changes the kinetic energy of flow velocity and fluid, different pressure is caused to damage
It loses, to achieve the purpose that decompression.Then by the adjusting of control and regulating system, make the fluctuation of downstream pressure and spring force phase
Balance, keeps constant downstream pressure in certain error range.
The advantage of the invention is that structure is simple, it is easy to operate.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of equipment work voltage-adjustable control loop；
Specific embodiment
1. it includes: pneumatic supply 1, air filtration that refering to fig. 1, the present invention, which specifically designs a kind of equipment work voltage-adjustable control loop,
Device 2, overflow pressure reducing valve 3, pressure gauge 4, oil sprayer 5, wherein pneumatic supply 1 is connect with air filter 2 by working line, works as gas
When potential source 1 enters filter by working line, liquid water, the liquid oil droplet in compressed air are separated, and filter off sky
Dust and solid impurity in gas, the key for influencing filtering accuracy is filter core, can be selected according to the needs of component below different
Filter core, reach corresponding filtering accuracy.
2. air filter 2 is connect with overflow pressure reducing valve 3 by working line, overflow pressure reducing valve 3 is the section by air inlet
Stream effect decompression, the balanced action of power and the overflow of overflow hole act on pressure stabilizing on diaphragm；Adjustment spring can make output pressure
Change in a certain range.
3. overflow pressure reducing valve 3 is connect with pressure gauge 4, oil sprayer 5 by connecting line respectively, and according to the degree of pressure gauge 4
Digital display shows that device pressure size is adjusted in the spring being adjusted on overflow pressure reducing valve 3, and oil sprayer 5 is a kind of special oiling
Device, when compressed air stream is out-of-date, it nebulizes lubricating oil injection, and the component for needing to lubricate is flowed into compressed air,
Achieve the purpose that lubrication.
