Abstract
The invention discloses a hydraulic control device, which is used for controlling the extension and retraction and regulating high and low speeds of an oil cylinder. The device comprises a proportional valve which comprises a direct-current power supply input end and an analog signal output end. The device solves the problem that mechanical equipment acts at a single slow speed in the modern manufacturing, and can control the oil cylinder to act at any speed at any position.
Description
Technical field
The present invention relates to the mechanical ﹠ electrical technology field, particularly a kind of flexible hydraulic control device that reaches fast speed regulation at a slow speed of controlling oil cylinder.
Background technique
Hydraulic transmission and Pneumatic Transmission are called the fluid transmission, are according to the 17th century emerging technology growing up of the hydrostatic pressure transmission principle that proposes of Pascal.
Hydraulic transmission has many outstanding advantages, so its application is very extensive, the plastic processing machinery of using as general industry, press, lathe etc.; Engineering machinery in the running mechanism, building machinery, farm machinery, automobile etc.; The metallurgical machinery that Iron And Steel Industry is used, lifting device, roll adjusting device etc.; Flood gate that the building hydraulic engineering is used and dam installation, riverbed lowering or hoisting gear, bridge operating mechanism etc.; Power station turbo machine arrangements for speed regulation, nuclear power plant or the like; The deck crane tool (winch) that boats and ships are used, fore door, bulkhead valve, stern propulsion device etc.; The huge antenna control gear that special technique is used, measurement buoy, lifting revolving stage etc.; The unwinding and winding mechanism of the cannon Effector that war industry is used, stabilizer for reducing ship rocking, aerial vehicle simulation, undercarriage and rudder control gear etc.
Hydraulic system is to provide dynamic foundation with motor, uses oil hydraulic pump that mechanical energy is converted into pressure, promotes hydraulic oil.By controlling the flow direction that various valves change hydraulic oil, thereby promote the action that oil hydraulic cylinder is made different strokes, different direction.Finish the different action needs of various device.
In modern times maximization manufacturing process, hydraulic control is seen everywhere, yet some needs fast quasi-stationary ground to move, and general control valve can not reach this effect.
Summary of the invention
In order to solve in machinery, stretching of control oil cylinder reaches the problem of fast speed regulation at a slow speed, and the present invention proposes following technological scheme:
A kind of hydraulic control device is used to control stretching of oil cylinder and reaches fast speed regulation at a slow speed, comprises a Proportional valve, it is characterized in that described Proportional valve comprises dc supply input, analog signal output.
More excellent, the pin A of described Proportional valve and pin B connect direct current 24V power supply, the output of the analog amount of the pin D of described Proportional valve and pin E welding system controller.
The beneficial effect that device of the present invention brings is:
Solved in the modern manufacturing production, machinery is with single moving at a slow speed.Can control oil cylinder moves with speed arbitrarily at an arbitrary position.

Embodiment
The present invention is further described below in conjunction with drawings and the specific embodiments.
A kind of hydraulic control device as shown in Figure 1 is used to control stretching of oil cylinder and reaches fast speed regulation at a slow speed, comprises a Proportional valve, and described Proportional valve comprises dc supply input, analog signal output.
The pin A of described Proportional valve and pin B connect direct current 24V power supply, the output of the analog amount of the pin D of described Proportional valve and pin E welding system controller.
As shown in Figure 1, the pin A and the pin B of device connect the DC24V power supply, the analog amount output of pin D and pin E welding system controller, and system exports analog amount as required, exports great amount, and oil cylinder just moves with great speed.Can control oil cylinder moves with speed arbitrarily at an arbitrary position.
Electro-hydraulic proportional valve is that the proportion electro-magnet input voltage signal produces corresponding actions in the valve, makes the operating valve spool produce displacement, and port size changes and finishes and the proportional pressure of input voltage, flow output element with this.Spool travel also can feed back with machinery, hydraulic pressure or electric form.
Its structure and the working principle of ratio involved in the present invention are as follows:
This valve is made up of switch valve, ratio regulating system, voltage-stabilizing system three parts.
A, switch valve: it is a break-make type solenoid valve, opens or closes valve port according to the electrical signal of controller.
B, ratio regulating system:mainly constitute by electromagnetic system, permanent magnet, ball valve assembly.When the controlled electric current of coil, produce and the identical electromagnetic force of permanent magnet end face polarity in the lower end surface of magnetic core, by the principle that the same sex is repelled each other, the two produces repulsive force, promotes permanent magnet and ball valve and moves down, and form corresponding aperture between the rubber valve port. electricity
Magnetic core magnetic field increased when stream increased, and the power of pushing permanent magnet open increases, and valve port opening increases; Magnetic core magnetic field reduced when electric current reduced, and the power of pushing permanent magnet open reduces, and valve port opening reduces.Controller can be regulated electric current automatically by the water temperature feedback signal and control gas flow automatically like this, thereby reaches the regulation and control water temperature, stablize the purpose of water temperature.
Electromagnetic force disappears when coil blackout, and permanent magnetism power is inhaled to magnetic core permanent magnet, moves close port on the ball valve; Permanent magnet is inhaled all the time to magnetic core under off-position, and ball valve is produced constant pulling force, makes this valve port have good sealing effect.
C, voltage-stabilizing system
After electric current was determined by set temperature value, magnetic force can be considered a constant force.Incoming pressure raises, and diaphragm applied force increases to top offset, and valve port opening is reduced; Incoming pressure descends, and diaphragm applied force reduces to bottom offset, and valve port opening is increased.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
