Description

The air pressure overload protection arrangement
Technical field
The present invention relates to a kind of air pressure overload protection arrangement.
Background technique
During work is produced; Many equipment all part adopt pressurized air as driving source, cause producing malfunctioning once in a while situation and produce compressed-air actuated air compressor pressure limiting switch because of frequent movement, thereby air compressor can not normally be unloaded; Compressed air pressure surpasses the qualification force value, produces potential safety hazard.To this situation, normally adopt and install safety valve additional and rush down pressure, but to rush down the baric flow amount too little because of safety valve, and can't make the air compressor unloading reduce force value, remove potential safety hazard, therefore need to adopt a kind of new practical technique solve the problems referred to above.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes existing technology, provide a kind of simple in structure, realize monitoring in real time and air pressure overload protection arrangement that can the whole-course automation operation.
The technological scheme that the present invention adopted is: the present invention is arranged on the main tracheae; The present invention includes casing, solenoid valve, adjustable pressure switch, the time relay, auxiliary reclay, pressure gauge; Said solenoid valve is arranged on the gas outlet of said main tracheae; Said adjustable pressure switch, the time relay, auxiliary reclay, pressure gauge all are arranged in the said casing; The said time relay is electrically connected with said solenoid valve, and said adjustable pressure switch is arranged on the main tracheae and with the said time relay and is electrically connected, and said voltmeter communicates with said adjustable pressure switch; Said auxiliary reclay is electrically connected with the said time relay, and said adjustable pressure switch, the said time relay all are connected with peripheral circuit.
The present invention also comprises band lamp alarm buzzer, digital display register, silencing apparatus, and said band lamp alarm buzzer is electrically connected with the said time relay, and said digital display register is electrically connected with the said time relay, and said silencing apparatus is arranged on the gas outlet on the said main tracheae.
The invention has the beneficial effects as follows: because the setting of the present invention through said casing, and all be arranged on said adjustable pressure switch, the time relay, auxiliary reclay, pressure gauge in the said casing, make the present invention simple in structure; Said solenoid valve can be monitored main endotracheal pressure condition in real time through the control of the said time relay and said auxiliary reclay, and can be the unlatching of the said solenoid valve of control in real time; In time get rid of potential safety hazard; So the present invention can be according to main endotracheal pressure condition, the action of control electromagnetic valve in real time; It is little to have overcome conventional security valve pressure release flow, can't make the difficulty of air compressor unloading pressure value.
Because the present invention also is provided with band lamp alarm buzzer in said casing, so when potential safety hazard took place, said band lamp alarm buzzer can in time be notified the staff, exempted the danger in the possible range; The application of said digital display register can provide the data foundation for maintenance and maintenance in the future, the speed of accelerating maintenance and safeguarding; On the gas outlet of main tracheae, install silencing apparatus, can a quiet working environment be provided, accomplish the enterprise objective that people-oriented for the staff.
Description of drawings
Fig. 1 is an easy structure schematic representation of the present invention.
Embodiment
As shown in Figure 1, in the present embodiment, the present invention is arranged on the main tracheae 9.The present invention includes casing 1, solenoid valve 2, adjustable pressure switch 3, the time relay 4, auxiliary reclay 5, pressure gauge 6, said solenoid valve 2 is arranged on the gas outlet of said main tracheae 9.Said adjustable pressure switch 3, the time relay 4, auxiliary reclay 5, pressure gauge 6 all are arranged in the said casing 1; The said time relay 4 is electrically connected with said solenoid valve 2; Said adjustable pressure switch 3 is arranged on the main tracheae 9 and with the said time relay 4 and is electrically connected; Said voltmeter 6 communicates with said adjustable pressure switch 3, and said auxiliary reclay 5 is electrically connected with the said time relay 4, and said adjustable pressure switch 3, the said time relay 4 all are connected with peripheral circuit.
The present invention also comprises band lamp alarm buzzer 7, digital display register 8, silencing apparatus 10, and said band lamp alarm buzzer 7, said digital display register 8 all are electrically connected with the said time relay 4, and said silencing apparatus 10 is arranged on the gas outlet on the said main tracheae 9.
The present invention is in running; When the internal pressure value in the main tracheae 9 during greater than the setup pressure value of said adjustable pressure switch 3; Said adjustable pressure switch 3 output voltages are to the said time relay 4 and said auxiliary reclay 5; Make their work and output voltage to said solenoid valve 2, said band lamp alarm buzzer 7 and said digital display register 8, they are worked simultaneously, begin to rush down pressure.When the said time relay 4 set times arrive, rush down to press and stop.If when this moment, said main tracheae 9 interior internal pressure values still surpassed the setup pressure value of adjustable pressure switch 3, get into and rush down the pressure cycle next time.Otherwise, be in the monitoring halted state.
In sum, the present invention can be widely used in air compressor control field.
