Abstract
The invention discloses a reversing valve. The reversing valve comprises a valve body, a valve core, a restoration device and a reversing device. The valve core is arranged inside the valve cavity of the valve body, the restoration device and the reversing device are respectively connected with the valve core, the valve core is connected with a heater, the valve body is provided with a temperature controller, the temperature controller is connected with the heater, and the inlet of the valve body is provided with a temperature sensor. The reversing valve does not require any supporting equipment, can be arranged far from a work station, is simple in structure and does not need any large reserved mounting space.
Description
Technical field
The present invention relates to a kind of selector valve, especially the selector valve that can heat fluid in valve and the pipeline at a lower temperature.
Background technique
As everyone knows, selector valve is 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 stream, and the valve of discharge degree and sequentially-operating control.In the actual production, the leakage of hydraulic element is huge to whole system working state influence, and not only build-up of pressure is not enough but also can damage whole hydraulic system.Existing hydraulic system all is equipped with cooling and heater, the low stickiness increase in pipeline pressure loss of oil liquid temperature increase and oil liquid temperature than high viscosity descend very easily cause hydraulic element in let out, so the temperature holding device seems particularly important in the hydraulic system.Yet it is lower in temperature, under the situation of hydraulic element and temperature holding device apart from each other, the relaying heater can remedy the loss of oil liquid temperature and guarantee that fluid arrives hydraulic actuator and can keep a comparatively suitable temperature, need bigger installing space and need auxiliary facility in the existing temperature holding device installation process, expense is also higher.
Such as Chinese patent: the hydraulic system (CN 101855457 A) with heating circuit, relate to a kind of hydraulic control system, wherein be used to the pump of hydraulic fluid supercharging to be connected with valve assembly, valve assembly has the displaceable valve element that flows to the load that is driven by hydraulic system with directing fluid optionally in chamber.Surface on the end face of valve element contacts self-controller via the hydrodynamic pressure of electric liquid electromagnetic valve.The surface of the valve element of proximate end face has undercutting to set up the leakage flow path optionally to activate solenoid valve, end face is pressurized to the normal actuation that is lower than the valve element but be high enough to cause that fluid returns the level of exhaust port, and the therefore temperature of hydraulic fluid in the increase system.
But above-mentioned fluid heating means are to utilize the backflow of hydraulic oil to realize, but this kind method can not guarantee at the good thermal effect that adds the change of penalizing backflow big and fluid.
Summary of the invention
For solve in the existing oil hydraulic circuit fluid at a lower temperature under the situation fluid stickiness rise, and existing equipment weak effect, relevant corollary equipment is many, complex structure, the rate of fault height, the shortcoming of maintenance difficult the invention provides a kind of selector valve.
The technical solution adopted for the present invention to solve the technical problems is: a kind of selector valve, its composition comprises: valve body, spool, recovery device, reversing arrangement, spool is arranged in the valve pocket of valve body, recovery device is connected with spool respectively with reversing arrangement, be connected with heater on the spool, valve body is provided with temperature controller, and temperature controller is connected with heater, and the valve body import is provided with temperature transducer.
Further described, center spool is provided with through hole, and the through hole center is provided with heater.
Further described, heater is any in heating wire or the heating stick.
Further described, temperature controller is provided with at least a pattern in telecontrol or the short range control.
Further described, the temperature controller of short range control mode is provided with by-pass cock, and the temperature controller of remote mode is provided with the connection that is connected with remote control equipment, also is provided with the supply lines that is connected with power supply on the temperature controller.
The invention has the beneficial effects as follows: need not corollary equipment, can be away from work station, simple in structure, need not the installing spaces of reserving more.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of selector valve sectional view of the present invention.
1. interfaces in the drawings, 2. electromagnet, 3. spool, 4. valve body, 5. valve pocket, 6. return opening, 7. returning spring, 8. blind hole, 9. right outlet, 10. import, 11. left side outlets, 12. temperature controllers, 13. temperature transducers, 14. electric heating wire.
Embodiment
Below in conjunction with the solenoid directional control valve embodiment of a heating of accompanying drawing narration, the invention will be further described.
In the drawings, be provided with valve pocket 5 in the valve body 4, valve body 4 is provided with import 10, left side outlet 11, the right side exports 9 and two return openings 6 and is communicated with valve pocket 5 respectively, valve pocket 5 is positioned at place, valve body 4 two ends opening, be combined with spool 3 in the valve pocket 5, spool 3 two ends are provided with the blind hole 8 of placing returning spring 7, valve body 4 two ends are provided with electromagnet 2, electromagnet 2 is connected with interface 1 on being arranged at electromagnet 2 shells, returning spring 7 one ends contact with blind hole 8 bottoms, the other end contacts with electromagnet 2, and when electromagnet 2 all was in dead electricity, spool 3 two ends were identical with the distance of electromagnet 2, spool 3 centers are provided with through hole, be provided with electric heating wire 14 in the through hole, electric heating wire 14 is connected with the temperature controller 12 that is arranged at valve body 4 outsides, and import 10 tube walls are provided with temperature transducer 13 and temperature transducer 13 is connected with temperature controller 12.
During use, the solenoid valve action, fluid enters import 10, temperature transducer 13 collecting temperature data also send temperature controller 12 to, temperature controller 12 is regulated the heating power of resistance wire according to setting temperature, spool 3 temperature rise, and fluid enters valve pocket 5 and flows out valve body 4 through valve pocket 5 heating backs from left side outlet 11 or right outlet 9.
Certainly also not only be implemented on the solenoid directional control valve among the present invention, can also can be implemented on other selector valves.Equally, heating equipment can also utilize other heater elements to replace, as heating stick.Temperature controller 12 also is not limited to be arranged on valve body 4 outsides, can also be arranged in the control room.Temperature transducer 13 also is not limited to valve body 4 imports 10, can also be arranged on the pipeline that is connected with valve body 4.Such non-creativeness change all drops within protection scope of the present invention.
