Abstract
The utility model relates to an alarming device, in particular to a low pressure alarming device for controlling pressure intensity of an air storage tank. The low pressure alarming device for controlling pressure intensity of the air storage tank comprises a power source, an alarm, an air pressure switch device and wires. The air pressure switch device is provided with an air inlet which is connected with an air outlet of the air storage tank, and the power source, the alarm and the air pressure switch device are connected through the wires to form a loop. The interior air pressure of the air storage tank is monitored by the air pressure switch device to further detect operation conditions of an air compressor indirectly, and once the air pressure of the air storage tank is too low, the air pressure switch device is closed, and the alarm is in operation. Therefore, the monitoring function can be achieved effectively, and improvement of product quality is facilitated.
Description
Technical field
The utility model relates to a kind of warning device, specifically, relates to a kind of low-pressure alarming device that is used to control gas holder pressure.
Background technique
In mechanical processing industry, numerous parts need be heat-treated technology after machine shaping, improve the performance of self, like intensity raising, wear resistance raising etc.; When heat-treating technology, oxidized for preventing part, around it, spray inert gas usually, like nitrogen; Nitrogen is the most cheap, and a supporting nitrogen generator just can be realized the supply of nitrogen.During nitrogen generator work; The air that needing a gas holder and air compressor to cooperate provides enough is originated; During the air compressor proper functioning, gas holder pressure is 0.8-0.85Mpa, and nitrogen generator normally moves; Produce enough nitrogen the workpiece in the heat treatment furnace is protected, prevent the workpiece decarburization and improve the quality of products.When the air compressor cisco unity malfunction, the pressure of gas holder can descend gradually, when pressure is reduced to the 0.4Mpa left and right sides; Nitrogen generator can not normally move; Even produce the self-locking shutdown, and do not provide nitrogen, lose shielding gas atmosphere in the heat treatment furnace; Influence the heat treatment of workpieces quality, cause product heat treatment defective.
In process of manufacture, because the working condition of air compressor can not obtain monitoring, if arrange the full-time staff, it is many to make that cost of production improves, so the situation of air compressor cisco unity malfunction happens occasionally.Device carries out the normal operation of supervisory device and do not have preferably as yet at present.
Summary of the invention
The purpose of the utility model is to solve the deficiency of existing technology; A kind of low-pressure alarming device that is used to control gas holder pressure is provided; This low-pressure alarming device can be monitored the pressure of gas holder; Thereby play the runnability of indirect control and supervision air compressor, give to produce to improve to guarantee, improve the up-to-standard rate of product.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of low-pressure alarming device that is used to control gas holder pressure; Comprise power supply, signalling device, baroswitch device and lead; Said baroswitch device is provided with suction port; Suction port is connected with an air outlet of gas holder, and power supply, signalling device and baroswitch device are connected to form the loop through lead.
Further, said signalling device comprises buzzer or electric bell.
Further, said signalling device also comprises beacon.
Further, said baroswitch device is provided with barometer.
Further, said baroswitch device is that magnetic helps the formula pressure gauge with electric contact.
The beneficial effect that the utility model is obtained is: a kind of low-pressure alarming device that is used to control gas holder pressure; Comprise power supply, signalling device, baroswitch device and lead; Said baroswitch device is provided with suction port; Suction port is connected with an air outlet of gas holder, and power supply, signalling device and baroswitch device are connected to form the loop through lead.The utility model is monitored the air pressure inside of gas holder through the baroswitch device, and then the working condition of indirect detection air compressor, in case gas holder air pressure is too low, the baroswitch device is closed, signalling device work; Thereby can play effective monitoring function, help improving the quality of products.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Reference character is:
1---power supply 2---beacon
3---electric bell 4---baroswitch device
5---heat treatment furnace 6---gas holder
7---air compressor 8---nitrogen generator.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is made specification further.
Embodiment: as shown in Figure 1; A kind of low-pressure alarming device that is used to control gas holder pressure; Comprise power supply 1, signalling device, baroswitch device 4 and lead; Said baroswitch device 4 is provided with suction port, and suction port is connected with an air outlet of gas holder 6, and power supply 1, signalling device and baroswitch device 4 are connected to form the loop through lead.
In the utility model when work,, the internal gas of gas holder 6 flows into baroswitch device 4 through the air outlet, when the inner pressure of gas holder 6 during less than predetermined value; Baroswitch device 4 closures, power supply 1, signalling device and baroswitch device 4 are connected to form the closed-loop path, signalling device work through lead; The air pressure inside of alert gas holder 6 is not enough; Air compressor 7 breaks down, and needs to safeguard, ends manufacturing operation; Prevent that being under the not enough situation workpiece at the nitrogen that nitrogen generator 8 is made also heat-treats at heat treatment furnace 5, plays the effect of protection product.
Further, said signalling device comprises buzzer or electric bell 3.Adopt electric bell 3 in the present embodiment.
Signalling device is arranged to buzzer or electric bell 3, can passes through sound alarm, point out corresponding operator.
Further, said signalling device also comprises beacon 2.
Through beacon 2 is set, can report to the police through light.Beacon 2 is connected in parallel in the loop with electric bell 3 in the present embodiment, so the work between beacon 2 and the electric bell 3 is separate, unaffected.Can certainly adopt the mode of series connection.
Further, said baroswitch device 4 is provided with barometer 5.
Can observe the air pressure of gas holder 6 through barometer 5 is set, when signalling device is worked, can see the air pressure of gas holder 6, cause misoperation, delay production in case short circuit appears in baroswitch device 4 from barometer 5.
Further, said baroswitch device 3 helps the formula pressure gauge with electric contact for magnetic.
Magnetic helps the formula pressure gauge with electric contact to help electric contact set, shell, regulating device and terminal box (connector assembly) etc. to form by measuring system, indication mechanism, magnetic.Magnetic helps the working principle of formula pressure gauge with electric contact to be based on bourdon tube in the measuring system under the pressure effect of measured medium; Chase after the end that makes bourdon tube and produce corresponding resiliently deformable one displacement; By pull bar through the transmission of gear drive and give amplification, by the indication on the fixed gear (together with contact) by measured value is indicated on scale.Meanwhile, when its instantaneous of (moving disconnected or moving closing) that contact with contact (upper limit or lower limit) on setting pointer, cause the circuit in the control system to be able to break off or connect, with the purpose that reaches automatic control and post a letter and report to the police.Adopt magnetic to help the formula pressure gauge with electric contact, pressure gauge and pressure switch are integrated, easy to use.
Below only be the application's preferred embodiment, equivalent technical solutions on this basis still falls into the application protection domain.
