Description
Technical field
The utility model relates to a kind of selector valve, relates in particular to a kind of solenoid directional control valve that has the electronic pressure sensor.
Background technique
Selector valve is meant the position control valve with two or more liquid forms and two above hydraulic fluid ports, be communication, cut-out and the commutation that realizes hydraulic oil flow, and the valve of discharge degree and sequentially-operating control, cocoa is divided into hand-operated direction valve, solenoid directional control valve, electro-hydraulic reversing valve etc. substantially.At present, various types of valve bodies are successfully applied to all trades and professions already, and become pith in the various device Hydraulic Power Transmission System, do not possess the condition that embodies the instant parameter of pressure in traditional electromagnetic switch valve arrangement, more can not realize therefore need implementing certain improvement according to this because the variation of parameter is used to control the function of other regulating elements.
The model utility content
At above defective, the utility model provides a kind of instant parameter of pressure that both can embody, and can easily control the solenoid directional control valve that has the electronic pressure sensor of other regulating element again, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of solenoid directional control valve that has the electronic pressure sensor, comprise that the valve body both sides are provided with electromagnet, valve body one side connects control box, described control box inside is made up of relay, control circuit board and display device, this control box inner chamber one side fixed installation has the control circuit board of integrated circuit unit, and described control circuit board bottom connects two relays respectively; Described control box inside center position is furnished with pressure transducer and is connected with valve body.
The beneficial effect that has the solenoid directional control valve of electronic pressure sensor described in the utility model is: by with common integrated being assembled on the change valve of pressure transducer, relay, control circuit board and electronic console, and become a part of selector valve, variation in pressure numerical value in the time of can not only accurately demonstrating selector valve work, and can pass through two relays, the parameter of She Dinging is effectively exported two groups of current signals on demand, conveniently is used to control other regulating elements; In addition, control circuit board can be exported the control electric current of 4-20mA/ (0-10V DC) simultaneously separately.

Embodiment
Shown in Fig. 1-2, the described solenoid directional control valve that has the electronic pressure sensor of the utility model embodiment, comprise by relay 3, control circuit board 5, pressure transducer 7, control box 8, display device 11 and valve body 13, described valve body 13 both sides are provided with electromagnet 1, the valve body 13 inner spools 12 of installing, these spool 12 two ends fixing spring seat 10 and winding springs 9; Described valve body 13 1 sides connect control box 8, described control box 8 center portions are furnished with pressure transducer 7 and are connected with valve body 13, this control box 8 inner chambers one side fixed installation has the control circuit board 5 of integrated circuit unit 6, described control circuit board 5 bottoms connect two relays 3 successively, control box 8 outsides that are positioned at relay 3 one sides are provided with connector socket 2, and control box 8 tops are provided with control case lid 4; Display device 11 is installed at described control box 8 tops, thereby makes relay 3, control circuit board 5, pressure transducer 7 and display device 11 integrated being assembled in the control box 8.
As shown in Figure 3-4, the described solenoid directional control valve that has the electronic pressure sensor of the utility model embodiment, pressure introduction port at former hydrovalve inserts a suitable pressure transducer 7, when the pressure of hydrovalve when 0-31.5MPa changes, the magnitude of voltage that the also corresponding output of pressure transducer 7 changes; Selected pressure transducer 7 is that a kind of compact structure, energy are high pressure resistant, the puzzled device of the biography of stable performance, and inipple is arranged, and is convenient to install.Arrange suitable position on hydraulic valve body 13, process a screw mouth, make it to communicate with the pressure port of hydrovalve, thereby pressure transducer 7 is installed on the hydrovalve reliably, the pressure parameter that pressure transducer 7 can be experienced hydrovalve changes.Traditional hydraulic system generally is that the pressure oil of exporting in the oil pump is imported power unit (as operating cylinder) drive loaded work piece through the control of various hydrovalves, and oil return is flowed back to fuel tank by hydrovalve, and its pressure-display adopts traditional pressure gauge.During work, when the electromagnet 1 at two ends, the hydrovalve left and right sides is not worked, hydrovalve spool 12 state of equilibrium that under the effect of the spring 9 at two ends, the left and right sides, mediates, A mouth, the B mouth of hydrovalve all are in closed condition, hydraulic oil is not exported, operating cylinder is not worked, (0-31.50MPa) change pressure that oil pump is sent into is sent into control circuit board 5 through the electrical signal that pressure transducer 7 converts variation to, by the processing input electronic console 11 of intergrated circuit 6, but the accurate numerical value of direct-reading 0.00-31.50MPa on the electronic console; Its integrated circuit unit 6 is sent into electrical signal relay 3 simultaneously, two relays all are in normally off, because the correlation of relay, when a relay is connected, can be simultaneously with another cut-off, by setting the on off operating mode that can change relay, when reaching pressure bottom 5MPa as hydraulic pressure numerical value when the hydrovalve input, the relay in its left side is connected, and output 4-20Ma/0-10VDC electric current can accurately show the variation in pressure of executive component under low loading condition on the electronic console; When the hydraulic pressure numerical value of hydrovalve input reaches the high-end 30MPa of pressure, the right side relay is connected, and triggers simultaneously the left side relay cuts out immediately, after relay is connected, output 4-20mA/0-10V DC electric current can accurately show the variation in pressure of executive component under high load condition on the electronic console.According to different demands, hydrovalve can be by setting the trigger point of two relays respectively, thereby reach the current signal of two relays outputs of any setting, makes it drive the control other electron component, so that this hydrovalve function increases.
In addition, control circuit board 5 can be exported the control electric current of 4-20mA/ (0-10V DC) in addition, is used to control other regulating element; Because the hydrovalve volume is less, arrange pressure transducer 7, control circuit board 5, integrated circuit unit 6, relay 3, electronic console 11, connector socket 2 integrated being combined in control box 8 bodies through selecting meticulously, thereby can conveniently be integrated on the hydraulic valve body 13, by such design arrangement, make the hydrovalve of charged minor pressure transducer also more harmonious in appearance.
