The utility model is achieved in that the air compressor air storage tank self-draining arrangement comprises filter, two-position two-way solenoid valve, flow controller and pressure controller.The entrance point of filter and two-position two-way solenoid valve joins.The outlet end and the flow controller of two-position two-way solenoid valve join.Flow controller and pressure controller join.
Said flow controller is an orifice restriction device with little throttle orifice.
Said pressure controller comprises valve pocket, valve seat, tee union body and spool.Valve pocket links to each other with valve seat.The threeway throttling bodies is contained in the valve pocket outside and forms an annular housing with valve pocket, and this annular housing communicates with the valve pocket inner chamber by the hole on the valve pocket.On the tee union body joint is housed.Spool is contained in the valve seat.Valve pocket is equipped with the adjustment screw vertically.Spring pad is equipped with in the inner of adjusting screw.Between spring pad and the spool stage clip is housed.Acorn nut is equipped with in the outer end of adjusting screw.Between acorn nut and the valve pocket, between valve pocket and the tee union body, between tee union body and the valve seat, between tee union body and the pipe joint and between spool and the valve seat seal washer is housed all.
The used two-position two-way solenoid valve of the utility model can adopt commercially available Normally closed type two-position two-way solenoid valve.Structure of filter is seen patent application " gas holder self-draining arrangement filter ", and application number is 96209639.3.
The utility model is that the Pnenmatic automatic switch that utilizes general air compressor all to have is control unit, is executive component with the drain solenoid valve, controls the air compressor air storage tank self-draining arrangement that principle designs according to flow and pressure limit.During use, the entrance point of filter and the drain opening of air compressor air storage tank are joined.The water of discharging from air compressor air storage tank filters through filter earlier, removes wherein contained dust and impurity, to guarantee the proper functioning of solenoid valve, flow controller and pressure controller.Concrete working procedure is: when the pressure of air compressor air storage tank drops to the minimum pressure that is limited by Pnenmatic automatic switch, the normally opened contact closure of Pnenmatic automatic switch, connect the power supply of the two-position two-way solenoid valve in air compressor motor and this self-draining arrangement, so air compressor is started working, the pressure of gas holder rises gradually.The bi-bit bi-pass electromagnetism, though the conducting of valve energising back, because the control of the controller that is stressed, drainage procedure has only after pressure in the gas holder rises to the cracking pressure of pressure controller and just begins.When the pressure of gas holder rises to the maximum pressure that is limited by the air compressor Pnenmatic automatic switch, the normally open contact of Pnenmatic automatic switch resets, cut off air compressor motor, cut off the two-position two-way solenoid valve power supply of self-draining arrangement simultaneously, so air compressor quits work, two-position two-way solenoid valve is closed, and cuts off drainage channel, and drainage procedure finishes.
The time length of air compressor air storage tank self-draining arrangement drainage procedure or the size of water displacement can be adjusted by the cracking pressure that changes pressure controller.The adjusting screw of adjusting pressure controller can change the cracking pressure of pressure controller.
The utility model has the advantages that:
1, can before the each shutdown of air compressor, rack up catchmenting in the gas holder automatically, in time, save manpower, and can keep the actual volume of gas holder constant substantially for a long time, improve the operation conditions of air compressor, prolong working life.
2, simple in structure, reliable, easy for installation, both can be used for new air compressor production, also be fit to old air compressor transformation.
Even the fault that being not closed completely appears in 3 two-position two-way solenoid valves, because the pressure limiting effect of pressure controller and the metering function of flow controller, can reduce compressed-air actuated air leakage greatly, and can effectively prevent from after gas holder pressure drops to the cracking pressure of pressure controller or turn-offs pressure, to continue gas leakage, therefore, reliability height.
