Abstract
The utility model provides a drainage device of an air compressor for an engineering plastic forming machine. The drainage device comprises an electronic valve which is arranged on a drainage pipe, a switch unit which is electrically connected with the air compressor, used to control start and stop of the air compressor and issues a first signal when an air storage tank is full of air and a time relay which is electrically connected with the switch unit and the electronic valve, and when the first signal triggers the time relay, the electronic valve is opened. The electronic valve can be opened automatically through the time relay and the electronic valve when the air storage tank is full of air, so that the function of drainage is achieved. The drainage device of the air compressor for the engineering plastic forming machine has the advantages of being simple in structure, reliable in performance and low in cost.
Description
Technical field
The utility model relates to the air compressor field, particularly a kind of drainage means that is used for the air compressor of engineering plastics molding machine.
Background technique
The air compressor that generally is used for the engineering plastics molding machine is when compressing high-pressure air, and moisture content contained in the air usually can accumulate the bottom in gas holder, therefore, needs in due course the ponding in the gas holder to be discharged.
Drainage pattern of the prior art mounted valve below gas holder after air compressor uses a period of time, is opened valve by special people Line Leader, thereby the ponding in the gas holder is discharged.Therefore, air compressor of the prior art has that automation efficient is low, the shortcoming of waste of manpower.
The model utility content
The utility model provides a kind of drainage means that is used for the air compressor of engineering plastics molding machine, needs the problem of artificial drainage to solve air compressor of the prior art.
For addressing the above problem; First aspect as the utility model; A kind of drainage means that is used for the air compressor of engineering plastics molding machine is provided, and air compressor comprises gas holder and waste pipe, and an end of waste pipe is connected with the water outlet of gas holder; Drainage means comprises: electronic valve, electronic valve are arranged on the waste pipe; Switch element is electrically connected with air compressor, is used to control the start and stop of air compressor and is full of at gas holder under the situation of gas send first signal; The time relay is electrically connected with switch element and electronic valve, and the first signal triggering time relay is opened electronic valve.
Further, switch element is a contactor.
Further, drainage means also comprises electronic box, and the switch element and the time relay are installed in the electronic box.
The utility model can be opened electronic valve automatically through the time relay and electronic valve after gas holder is full of gas, to realize the function of draining, have simple in structure, reliable performance, advantage that cost is low.
Description of drawings
Fig. 1 schematically shows the structural representation of the utility model.
Embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As the first aspect of the utility model, a kind of drainage means that is used for the air compressor of engineering plastics molding machine is provided.As shown in Figure 1, air compressor comprises gas holder 10 and waste pipe 20, and an end of waste pipe 20 is connected with the water outlet of gas holder 10.Drainage means comprises: electronic valve 30, electronic valve 30 are arranged on the waste pipe 20; Switch element 40 is electrically connected with air compressor, is used to control the start and stop of air compressor and is full of at gas holder 10 under the situation of gas send first signal; The time relay 50 is electrically connected with switch element 40 and electronic valve 30, and the first signal triggering time relay 50 is opened electronic valve 30.Preferably, switch element 40 is contactors, and certainly, switch element 40 also can be other switching device.
In a preferred embodiment, drainage means also comprises electronic box 60, and switch element 40 is installed in the electronic box 60 with the time relay 50.
Please refer to Fig. 1, electronic valve 30 is installed on waste pipe 20.Switch element 40 comprises first contact sets and second contact sets, and wherein, first contact sets is used to control the work of air compressor, and second contact sets is used for the control time relay.When air compressor was in the gas storage state, first contact sets of switch element 40 was in closed state, and at this moment, air compressor gets.After the gas holder 10 of treating air compressor was full of gas, first contact sets of switch element 40 was broken off.At this moment, second contact sets of switch element 40 is closed, thereby sends first signal, so that the coil of the time relay 50 gets is electric, so under the control of the time relay 50, the coil of electronic valve 30 gets electric, thereby waste pipe 20 is opened.Like this, the ponding in the gas holder 10 will be discharged through waste pipe 20.Then, through behind the certain hour, the time relay 50 breaks off, thereby makes the coil losing electricity of electronic valve 30, so electronic valve 30 cuts out, stops draining.So back and forth, just can realize the automatic draining of air compressor.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
