Characteristically, a flexible sealing cushion is arranged between the upper cover and the lower cover of the pilot valve. Air inlet is communicated with air outlet of incoming executor, and air inlet is provided with an internal piston. Inner end of the piston contacts the flexible sealing cushion, and outer end of the spring is provided with a spring. Air outlet of the incoming executor is provided with a unilateral valve plug. Air inlet of exhausting executor is communicated with a vent. An exhausting valve core is arranged inside air inlet of the exhausting executor, and inner end of the exhausting valve core contacts the flexible sealing cushion as well. The utility model is beneficial to achieve pneumatic servocontrol, digital control and self-adaptability by pneumatic pilot technology. Openness and closedown of pilot air are controlled by the piezoelectric valve. High pressure air is controlled by low pressure air. With easy adjustment, the utility model shortens time needed in adjustment of the electric transverter and reduces requirement to the executor. Moreover, the utility model has the advantages of convenient and quick use, precise control, low gas consumption, low operational cost, reliable and stable performance.
Description
Technical field
The utility model belongs to a kind of parts of electropneumatic transducer, particularly a kind of intelligent electric gas converter pilot valve.
Background technique
Electropneumatic transducer is used to control the pneumatic circuit of pneumatic straight stroke valve, angular travel valve, cylinder valve or other similar functions.Traditional electropneumatic transducer is to adopt force balance principle and nozzle-flapper structure, be analog amount control, therefore precision is lower, adjust maximum pressure position and the minimum pressure position that to calibrate final controlling element in advance simultaneously, also will distinguish positive and negative effect, not only adjustment is number numerous, length consuming time, and to the requirement of final controlling element than higher, operating cost is higher.
The model utility content
The purpose of this utility model provides a kind of intelligent electric gas converter pilot valve, realized pneumatic servo control with pneumatic frontier technology, turnover and shutoff by piezo electric valve control pilot gas, reduced requirement to final controlling element, be easy to adjust, realize degree of precision control, reduce operating cost, compact structure, stable and reliable for performance.
The purpose of this utility model is achieved by the following technical solution: it comprises pilot valve loam cake, pilot valve lower cover, piezo electric valve etc., it is characterized in that: assemble elastic sealing gasket between pilot valve loam cake and pilot valve lower cover; Cover under the pilot valve air source inlet is set, discharge the final controlling element gas access, enter the final controlling element gas outlet; In the air source inlet and enter the final controlling element gas outlet and communicate, and in air source inlet the stifled piston of assembling band sealing plug, the inner contact resilient sealing gasket of piston, the outer end assembling spring of piston enters the final controlling element gas outlet and assembles unidirectional valve plug and sealing gasket; Discharge connection relief opening in the final controlling element gas access, in discharging the final controlling element gas access, assemble exhaust plug, the inner contact resilient sealing gasket of exhaust plug; Assembling source of the gas gas enters pressure governor between pilot valve loam cake and pilot valve lower cover.
The utility model has the advantages that: the utility model has been realized pneumatic servo control with pneumatic frontier technology, because the utility model is numerically controlled executive component, by employing of the present utility model, realized digital control and adaptivity, self adaption promptly adopts different pulse duty cycles at different controlling object.By the turnover and the shutoff of piezo electric valve control pilot gas, control big pressed gas with little pressed gas, adjust easily, shortened the adjustment time of electropneumatic transducer, reduced requirement to final controlling element, convenient and swift, only needed 3-5 minute can finish adjustment.Realized degree of precision control, air consumption is little, and operating cost is low, compact structure, and volume is little, and is in light weight, stable and reliable for performance.

Embodiment
See Fig. 1-4, concrete structure is as follows: pilot valve loam cake 16 and pilot valve lower cover 17 connect by bolt 20, two piezo electric valves 14,15 of assembling in pilot valve loam cake 16, and piezo electric valve is an existing product.Assembling elastic sealing gasket 13 constitutes air bag between elastic sealing gasket 13 and the piezo electric valve between pilot valve loam cake 16 and pilot valve lower cover 17; Air source inlet 6 on the pilot valve lower cover 17 and enter final controlling element gas outlet 7 and have gas circuit to communicate, the piston 18 of assembling band sealing plug stifled 3,4 on the path in air source inlet 6, the inner contact resilient sealing gasket 13 of piston 18, the outer end assemble compressible spring 5 of piston 18, pressure spring 5 is pressed in sealing by external fixator and stops up on 4.Enter final controlling element gas outlet 7 places and assemble unidirectional valve plug 8 and sealing gasket 22; Discharge final controlling element gas access 9 and be communicated with relief opening 11, assembling exhaust plug 12 and mold insert 10 in discharging final controlling element gas access 9, the outer end assembling sealing gasket 19 of exhaust plug 12 by gas circuit.The inner contact resilient sealing gasket 13 of exhaust plug 10; Assembling source of the gas gas enters pressure governor 21 between pilot valve loam cake 16 and pilot valve lower cover 17, and this pressure governor 21 adopts the existing product structure.
Working principle: gas turnover and shutoff in the utility model control final controlling element.1, to final controlling element output services gas: pilot gas g enters piezo electric valve 14 from aperture 1, and the airbag aeration between elastic sealing gasket 13 and the piezo electric valve 14, air bag promote exhaust plug 12 relief opening 11 is closed, and gas d can not discharge in the final controlling element.Meanwhile, pilot gas g also enters another piezo electric valve 15, airbag aeration between elastic sealing gasket 13 and the piezo electric valve 15, air bag is pushed pressure spring 5 open by piston 18 and is opened gas circuit, the source of the gas gas f enters final controlling element by unidirectional valve plug 4 from entering final controlling element gas outlet 7, realizes the control of pilot gas g duration of ventilation length and the adjustment of control accuracy by the duration of ventilation length of controlling piezo electric valve.2, close working gas: piezo electric valve 15 is not inflated in air bag, and at this moment, pressure spring 5 resets, and gas source air inlet 6 is closed.Another piezo electric valve 14 is inflated in air bag, and at this moment, relief opening 11 is closed, and the inlet and outlet mouth of working gas all is closed, and under the gas effect, close by the mouth that gas is entered final controlling element in final controlling element for sealing gasket 22 simultaneously, and gas can not pass in and out final controlling element.3, the final controlling element working gas enters: two piezo electric valves are not all inflated in air bag, and air source inlet 6 is closed under the effect of spring 5, and exhaust plug 12 is opened under the gas effect in final controlling element, discharge by relief opening 11.
