Such as, lacing film corrosion testing device in the pipeline described in detail in the utility model patent CN202974817U description that on June 5th, 2013 authorizes.This device includes protective cap, hanger, pedestal, film hangers, hydrops cabin; hanger is fixed on above pipeline by pedestal, is cased with protective cap above hanger, is fixed with film hangers below hanger; being hung with least one set test piece on film hangers, the bottom test piece of film hangers is positioned at hydrops cabin.Although this device solves pipeline corrosion test problems, but when preparation this lacing film corrosion testing device of taking-up is observed when, owing to the pressure in pipeline may be bigger, it is possible to, at the installation position of this lacing film corrosion testing device ejection liquid or gas, operator take out this lacing film corrosion testing device and causes potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of safety hanger device, takes out the safety problem of hanger device in order to solve operator.
In order to solve the problems referred to above, this utility model a kind of for corrosive pipeline detection hanger device by the following technical solutions:
Hanger device, including plug, film hangers, film hangers includes the support body that lacing film bar and plug bottom connect, plug has pressure release through hole, pressure release through hole upper end connects fixed valve, being additionally provided with the medium inlet entering for manifold pressure medium and communicating with pressure release through hole on hanger device, described medium inlet is located at plug bottom or is located on support body and is communicated with in support body the flow-guiding channel of pressure release through hole and medium inlet.
A kind of improvement as a kind of hanger device for corrosive pipeline detection of this utility model, described medium inlet is located on support body, described support body is the body of upper and lower opening, described flow-guiding channel is located in body, body upper shed has for being connected fixing female thread with plug pressure release through hole lower end, and body under shed is medium inlet.
As the further improvement of a kind of hanger device for corrosive pipeline detection of this utility model, described support body is made up of corrosion-resistant material.
As the further improvement of a kind of hanger device for corrosive pipeline detection of this utility model, described lacing film bar is made up of insulation corrosion-resistant material.
Beneficial effect is analyzed:
In sum, a kind of hanger device for corrosive pipeline detection that this utility model provides, after corrosive pipeline has detected, when operator take out this kind of hanger device, due to the valve of plug upper end, plug is provided with the pressure release through hole being connected with valve, can first open valve pressure release, then take out hanger device, accomplish without press operation, thus ensure that operator take out the safety of operation.Centered by the pressure release through hole on valve during hole, facilitate production and processing manufacture.
Support body is provided with flow-guiding channel, and flow-guiding channel one end connects plug pressure release through hole lower end, and the flow-guiding channel other end is medium inlet port.When operator open valve, the medium inlet port from support body of the pressure medium in pipeline enters, and is then passed through the pressure release through hole of plug, then by valve, discharge line, completes a pressure leak process, thus ensures safety when operator take out hanger device.
Support body is made up of corrosion-resistant material, it is to avoid lacing film falls into because support body is corroded in pipeline, extends corrosion coupon device service life.
Lacing film bar is made up of insulation corrosion-resistant material, can avoid the absorption to minute impurities during this kind of corrosion coupon device busy, avoids pipeline corrosion material also to the corrosion of the parts of other hanger devices, can improve the accuracy of corrosivity monitor simultaneously.
