Abstract

The utility model discloses a steel drum leakage testing device, and aims to provide a steel drum leakage testing device, which is simple in testing method, capable of easily finding out leaking spots and high in efficiency. The steel drum leakage testing device is characterized in that a gas storage tank, a first gas-water separator, a throttle valve, a pressure gauge, a check valve and a second gas-water separator are sequentially connected, a gas outlet of the second gas-water separator is connected with a gas inlet of an electromagnetic valve, a gas outlet of the electromagnetic valve is connected with a gas inlet pipe of a drum by a pressure sensor, and a joint is connected to the tail end of the gas inlet pipe of the drum. A signal output end of the pressure sensor is connected with a pressure signal input end of a PLC (programmable logic controller), a control signal output end of the PLC is connected with a control signal input end of the electromagnetic valve, and the PLC is respectively connected with a display screen and a detector switch. The leakage testing device adopts air for detection, can maintain a clean state inside the steel drum, avoids contacting with water, and is reliable in quality.

Description

The steel drum leakage testing device
Technical field
The utility model relates to a kind of steel drum leakage testing device.
Background technology
In the process of steel drum renovation,, need carry out leak test work to the steel drum after the renovation in order to ensure the renovation quality.At present, leak test adopts the method that water filling detects.Owing to have water residual easily in the steel drum after the water filling, influence the quality of steel drum.And, since water at leak source everywhere in flow state, be not easy to search leak source.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of detection method simple, find leak source easily, the steel drum leakage testing device that efficient is high.
The utility model is achieved through the following technical solutions:
A kind of steel drum leakage testing device, it is characterized in that, gas-holder, first moisture trap, throttling valve, tensimeter, stop valve, second moisture trap connect successively, the gas outlet of described second moisture trap is connected with the inlet end of solenoid valve, the outlet side of described solenoid valve is connected by the draft tube of pressure transducer with bucket, and the draft tube end of bucket is connected with joint; The signal output part of described pressure transducer is connected with the pressure signal input end of PLC controller, and the control signal output ends of described PLC controller is connected with the signal input end of solenoid valve, and described PLC controller is connected with detector switch with display screen respectively.
Described PLC controller is connected with working station indicator.
Described gas-holder is connected with source of the gas by tracheae.
The utlity model has following technique effect:
1, leakage testing device of the present utility model adopts air to detect, and can keep the clean conditions in the steel drum, avoids contacting reliable in quality with water.
2, defective steel drum can be found leak source by smearing suds at easy leak, and is easy to use, the reliability height.
3, leakage testing device of the present utility model can detect many steel drums simultaneously, has improved work efficiency.And, the gas in the bucket of finishing after testing can be charged in other steel drums, pressure gas can be used repeatedly, saved cost.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model steel drum leakage testing device,
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The synoptic diagram of the utility model steel drum leakage testing device as shown in Figure 1, gas-holder 3, first moisture trap 4, throttling valve 5, tensimeter 6, stop valve 7, second moisture trap 12 connect successively, the gas outlet of described second moisture trap 12 is connected with the inlet end of solenoid valve, the outlet side of described solenoid valve is connected by the draft tube 8 of pressure transducer 10 with bucket, and draft tube 8 ends of bucket are connected with joint 9.The signal output part of described pressure transducer is connected with the pressure signal input end of PLC controller 11, and the control signal output ends of described PLC controller is connected with the signal input end of solenoid valve, and described PLC controller is connected with detector switch with display screen respectively.
For the ease of observing, described PLC controller is connected with working station indicator.
Described gas-holder 3 is connected with source of the gas 1 by tracheae 2,
During use, open detector switch, PLC controller control electromagnetic valve is opened, and gas enters in the bucket by gas sensor through after the gas-water separation.After gas was full of bucket, the PLC controller cut out solenoid valve.At this moment, pressure transducer output promptly is the interior pressure of bucket.The PLC controller compares the pressure in the input bucket of bucket internal pressure and setting, if internal pressure in allowed limits at the appointed time, it is qualified then to show on display screen, lights qualified pilot lamp simultaneously.If the scope of the permission that surpasses of internal pressure at the appointed time then shows defectively, light defective pilot lamp simultaneously on display screen.
