Description
Technical field
The present invention relates to production protective devices, and in particular to a kind of cylinder filling weighing automatic disconnecting device.
Background technique
With the continuous promotion that safety management requires, filling for compressed liquefied gas must use weighing to automatically cut off dress
It sets, prevents carbon dioxide in steel cylinder from exceeding filling weight and causing safety accident.The hand when carbon dioxide filling weight has arrived setting value
Dynamic control closes valve and overcharges phenomenon really due to person's development and operating delay, and there are security risks.
Summary of the invention
The technical problem to be solved by the present invention for the above-mentioned state of the art is to provide a kind of at low cost, structure is simple
Cylinder filling weigh automatic disconnecting device.
The technical scheme of the invention to solve the technical problem is:
A kind of cylinder filling weighing automatic disconnecting device, including mechanical scale, gas tank are placed on mechanical scale, and feature exists
In: the mechanical scale is equipped with limiter；The limiter position is additionally provided with photoelectric proximity switch；Limiter connection have after
Electric appliance；Also connection has guide electromagnetic valve to the relay simultaneously；The solenoid valve is arranged in the air inlet pipe of gas tank；The electricity
Magnet valve, which also couples, alarm；The air inlet pipe is connected on pipeline, and air pump passes sequentially through intermediate relay and pressure gauge and pipe
Road connection.
Further, it is carbon dioxide that the air pump, which is filled with the gas of pipeline,.
Further, the limiter is located on the default scale of mechanical scale.
Further, the alarm is LED combined aural and visual alarm.
Further, the air pump is low temperature air pump.
Still further, the relay is circumscribed with power supply.
The beneficial effects of the present invention are: effective guarantee that overvoltage condition will not be generated in the process of running, greatly reduce
Security risk, and cost depletions can be substantially reduced during use, it achieves many things at one stroke.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The embodiment of the present invention is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, the arm beam of steelyard of mechanical pound lifts (stroke when filling CO 2 cylinder filling amount reaches setting value
It 2cm) blocks close to switching light sources, receives reflected light close to switch, relay contact, which is attracted, connects solenoid valve electromagnetic coil, electricity
Magnet valve work, valve are closed, and LED combined aural and visual alarm flashes alarm simultaneously, and carbon dioxide stopping fills.After the arm beam of steelyard resets, break
Switch power supply, relay contact separation, valve are opened, and carbon dioxide steel cylinder continues to fill.
The case where pumping while cutting off there are several in carbon dioxide filling process, will result in and fill manifold pressure suddenly
Increasing above operating pressure leads to safety valve jumping up, and a large amount of low-temperature carbon dioxide liquid spray.For support personnel and filling tube
The safety in road is provided with a set of overpressure protection apparatus, i.e., by electro connecting pressure gauge, intermediate relay and low temperature on filling pipeline
The normally closed point connection of liquid pump, safety valve set pressure 10.0MPa, therefore the electro connecting pressure gauge upper limit is set as 7MPa, when
When pressure value reaches the upper limit, cryogenic pump dump stops working.
By actual motion, the action response time of the device is 10ms, and the carbon dioxide weight after filling is equal after claiming again
No more than the 0.5% of setting value.Not only it had solved because of security risk existing for overcharging, but also had reduced costs, while having met market
Demand.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
For those of ordinary skill, several improvements and modifications without departing from the principles of the present invention should be regarded as protection of the invention
Range.
