Field controller creates and controls solenoid and produce the controller of electromagnetic field, to the interval time producing electromagnetic field for the second time again after controlling time and the length producing the electromagnetic field time that electromagnetic field produces and every time producing electromagnetic field；

Air inlet pipe creates the air inlet connecting pump gas shell and connects the hollow pipe of the pipeline of output natural gas in the natural gas well；

Air inlet create natural gas enter in the extrusion chamber in pump gas shell through via, manufacture in the centre sealing neck；Manufacturing in the upper end of the air inlet sealed in neck and have annular sealing surface, when being fitted without sealing cap on the annular sealing surface sealing neck of protecting crust lower end, inlet chamber communicates with air inlet；

In order to ensure environmental protection and energy saving pressure take out natural gas facility can normal operation, adopt what field controller controlled solenoid to connect being switched on and off of circuit；

In order to ensure that protecting crust can protect solenoid keep shape and be not easy deformation, the cavity of protecting crust manufactures the skeleton having support；

In order to enable to answer the natural gas in the extrusion chamber in magnetic piston driving pump gas shell to enter air outlet valve, adopt promote spring as promote answer natural gas in magnetic piston stroking upward compression extrusion chamber and in natural pressure air valve；

Being provided with solenoid in protecting crust, solenoid is fixed on the lower part outside pump gas shell, and protecting crust is fixed on the outside protection solenoid of the bottom of pump gas shell；Below the outside of protecting crust, one side is fixed with foot rest, and the lower end of foot rest is lower than the position of the air inlet of pump gas shell lower end；The circuit connecting solenoid is connected with field controller, and the circuit of field controller is connected with insulated electric conductor, and field controller is arranged in protecting crust；Sealing cap is installed in pump gas shell, promotes spring, answers magnetic piston, restriction orifice, promote spring to be arranged on the lower part of inner chamber of pump gas shell, answer magnetic piston to be arranged on the upper part of inner chamber of pump gas shell, promote spring top to be pressed in the lower end answering magnetic piston；It is fixed with a point water restriction plate in the spacing hole of upper end of magnetic piston answering, answers magnetic piston can slide up and down at the interior intracavity of pump gas shell；It is fixed with restriction orifice in the spacing hole answering magnetic piston upper end, the annular sealing surface sealing neck end answering in point compression of upper part of magnetic piston there is the inner sealing surface sealing cap matched, seal cap answering can move up and down between compression and restriction orifice dividing of magnetic piston, seal cap and coordinate the inlet channel that can seal or open the extrusion chamber entered in pump gas shell with the annular sealing surface answering magnetic piston；The periphery sealing neck of the lower end in pump gas shell is cased with sealing cap, seals and the periphery sealing neck of cap lower end in pump gas shell can slide up and down；The inner sealing surface sealed in cap coordinates the inlet channel that can seal or open in entrance pump gas shell with the annular sealing surface sealing neck end；When answering magnetic piston stroking upward, the lumen portion answering the lower sections of pump gas shell of magnetic piston is inlet chamber；When answering magnetic descent of piston, the lumen portion answering the pump gas shell of magnetic piston upper part is extrusion chamber；Air inlet position in the lower end of pump gas shell is fixed with air inlet pipe, and the endoporus of air inlet pipe communicates with air inlet；Being provided with air outlet valve in the upper end of pump gas shell, the lower part of air outlet valve is fixed in the centre bore of the overlying one end of pump gas shell；The upper end of air outlet valve is exposed the part of the upper surface of pump gas shell and is connected with the pipeline of conveying natural gas by flexible pipe or hard tube。
