Background technology
Workshop has a lot of place to need to use compressed gas when producing, and such as rotary file, air gun, determines torsion and pulls
Hands, swivel nut installation tool, three coordinates etc., the compressed gas that these terminals are complicated with providing compressed-air actuated air compressor composition
Body pipe network.In the case of air compressor power stability, the gas pressure size of single terminal depends on use in pipe network
Terminal quantity, owing to these terminals are in variable interval switch all the time so that be directly accessed the pressure of the single terminal of main pipeline
Play pendulum.For being in the terminal of normal work, the air pressure in pipeline diminishes suddenly, and may result in can not
Normal work, it is necessary to manually regulation pipeline air valve, makes air-flow quantitative change big, it could be allowed to resume work；And if the pressure of pipeline
Air pressure becomes big, exceedes the operating pressure of terminal, if not going regulation, the most easily makes to be in the terminal merit of high-pressure work
Can be impaired.
Summary of the invention
This utility model purpose is a kind of stable-pressure device provided for above-mentioned deficiency, can be by dynamically regulating gas
Pressure and to terminal provide relatively stablize air pressure, simple in construction, stable performance.
The technical solution of the utility model is: include cylinder, voltage regulation cylinder；Described cylinder includes cylinder body, inner chamber of cylinder block warp
Piston is separated into the left chamber that right chamber is connected with air inlet pipe, for moving left and right according to gas pressure change in left chamber
Piston be connected with push-pull bar one end, offset on the left of piston for the spring one balancing right chamber gas pressure inside, be used for putting down
In weighing apparatus left chamber, the spring two of gas pressure offsets on the right side of piston.The effect of regulation spring is to preset balance, makes piston non-
Duty is maintained at metastable position.Spring two can make the making of cylinder become simple simultaneously, owing to right chamber is non-
Completely enclosed state, it is impossible to be balanced left chamber's gas pressure, needs the regulation effect of spring two to offset left chamber's air pressure
Effect, prevents piston from excessively bumping against with hollow adjusting nut to the right, prevents active blade upper end to the right beyond vertically side the most simultaneously
To and make regulation effect lose efficacy.The effect of regulation spring is to close the retroaction to spring two at trachea to carry out cushioning balance, also
Prevent from push-pull bar one from being made active blade turn to the most counterclockwise by improper External Force Acting to cause damaging.Set on described voltage regulation cylinder cylinder body
Having the outlet that the import being connected with air inlet pipe is connected with escape pipe, voltage regulation cylinder cylinder body exports out built with being used for adjusting
The active blade of tolerance；Through right chamber in the middle part of push-pull bar, the push-pull bar other end connects with active blade in stretching into voltage regulation cylinder cylinder body
Connect.
Described left chamber is placed on outside spring guide built with spring guide, spring one, and spring two is placed on and is positioned at right chamber
Push-pull bar on.
Described push-pull bar one end has the slot coordinating assembling with spring guide.
In the middle part of described push-pull bar, warp is used for adjusting spring one length, the adjusting part of spring two length passes right chamber.Bullet
Spring two in use whole process is in compressive state, and adjusting part screws back-out by the hollow adjusting nut of regulation and regulates bullet
The thrust of spring thus preset airline pressure, spring one acts primarily as assosting effect.
The hollow adjusting nut that described adjusting part includes Adjusting bolt Adjusting screw, is threadedly connected in Adjusting bolt Adjusting screw.
Described right chamber is provided with installing hole, and Adjusting bolt Adjusting screw is loaded at installing hole.
In the middle part of described active blade in rotating shaft is loaded on voltage regulation cylinder cylinder body, active blade end is hinged with push-pull bar.
Described push-pull bar end is equipped with adjustable telescopic bar, and active blade end is hinged with adjustable telescopic bar through connecting rod.
The effect of connecting rod mainly connects pin at two, due to active blade in rotary course relative to push-pull bar two at vertical direction
Position is not in stopping change, for preventing from suppressing strength, increases connecting rod and realizes being similar to the effect in joint, reduce active blade and push-and-pull
The damage of bar two.
Described left chamber is provided with the QI KOU being connected with air inlet pipe.
Described cylinder is connected with voltage regulation cylinder through connecting post.
When using this utility model, by default outlet pressures such as regulation regulation valve, hollow adjusting nut and regulation screws,
In use along with air inlet overpressure change, the bypass tracheal pressure being attached thereto change therewith and with spring phase interaction
Move left and right by promotion piston, make voltage regulation cylinder inner circular catch turn clockwise or counter-clockwise by push-pull bar effect
Dynamic, thus affect the gas gross entered in escape pipe, reach pressure stabilization function.This utility model makes simple, dependable performance, dimension
Protect conveniently, lean is produced important in inhibiting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In Fig. 1, this utility model include air inlet pipe 9, bypass trachea 3, Pressure gauge, pressure regulator valve 11, voltage regulation cylinder 7, cylinder 21,
Escape pipe 1, hollow adjusting nut 24, push-pull bar 17, adjustable telescopic bar 19, piston 27, spring, bearing 31 etc. form.Air inlet
Pipe 9 connects compressed air main line, Pressure gauge 2 10, bypass trachea 3, pressure regulator valve 11 and voltage regulation cylinder 7 by fast insertion type joint.Other
Road trachea 3 connects air inlet pipe 9 and cylinder 21 by fast insertion type joint 4.Voltage regulation cylinder 7 and cylinder 21 by being connected post 20 and welding, gas
Cylinder 21 is welded into a whole with bearing 31.Voltage regulation cylinder 7, cylinder 21 are cylindrical structural.Voltage regulation cylinder 7 and pressure regulation cylinder cap 5, sealing gasket
6 connected by fastening bolt after formed closed cavity.Fairlead 15, the suitable position of axis sustained height it is provided with bottom voltage regulation cylinder 7
Install rotating shaft 18.Pressure regulation cylinder cap 5 is provided with outlet, exports and connects escape pipe 1 by fast insertion type joint, and escape pipe 1 is connected to pressure
Power table 1.Cylinder 21 is connected by fastening bolt 30 with cylinder head 22.The centrally disposed spring guide of cylinder bottom 25, spring one
26 are arranged on spring guide 25.The centrally disposed Adjusting bolt Adjusting screw of cylinder head 22 23.Adjusting bolt Adjusting screw 23 is threaded connection hollow regulation
Nut 24.Push-pull bar 17 one end is connected with piston 27 through hollow adjusting nut 24 and uses locknut 28 to fix, this end leading portion
Hollow coordinates with spring guide 25, equipped with spring 2 29 on the push-pull bar 17 between piston and hollow adjusting nut 24.Push-pull bar
17 other ends and adjustable telescopic bar 19 are connected by regulation screw 16, during this end leading portion has and coordinates with adjustable telescopic bar 19
