Description
Technical field
The present invention relates to detection devices, and in particular to a kind of high pressure charge and discharge rubber lined hose strength test device.
Background technology
With the continuous improvement of people's living standards, life gas demand increasingly increases, meanwhile, environmental protection is to factory
The emission request of exhaust gas is increasingly stringenter, and many industry coal-boilers are forbidden to use and eliminate, it has to use gas fired-boiler instead, because
And the demand rapid growth of industrial combustion gas.The pressure vessel quantity of storage combustible medium is increasing, and combustion gas is existed using turnover rate
Accelerate, the transportable pressure vessel that input transport uses is more and more, and either hose quantity still implements refuting for handling operation
Number is connect all to be on the increase.These Pressure vessels needs, which are connect with transportable pressure vessel by hose, carries out handling work
Industry.According to TSG21-2016《Fixed safe technology of pressure vessel Supervision Code》In correlation about pressure vessel periodic inspection
It is required that pressure vessel fills unit or must carry out 1 pressure test every year to charge and discharge rubber lined hose using unit, test pressure is
1.5 times of nominal pressure, hose ne-leakage is without exception in experiment is deformed into qualification.
Currently, using unit to the self-test capability wretched insufficiency of hose, safety accident is easily induced in the self-test course of work,
In order to reduce security risk, mostly uses the special inspection technical body of commission greatly using unit and annual test is carried out to hose.Inspection body from
When thing high pressure charge and discharge rubber lined hose examines work, due to a lack of the hose connection device of profession, that there are handling procedures is cumbersome, checkability is low
Under, the realistic problem that is difficult to ensure of fixture easy damaged hose, docking sealing performance, while there is also manual fixtures in high-potting
When the security risk that loosens.
Currently, the domestic inspection for charge and discharge rubber lined hose, minority possesses testing equipment then voluntarily to charge and discharge rubber lined hose using unit
Pressure test is carried out, the use unit without having test condition then entrusts special equipment testing agency to carry out its charge and discharge rubber lined hose
Pressure test.
However, in practice examining work, either using unit or inspection detection unit, there has been no a set of perfect
Charge and discharge rubber lined hose examines equipment.Now in testing agency, the verifying attachment used is all fairly simple and handling procedure is cumbersome, work
Efficiency is low, examines the time-consuming longer of hose.Hose reviewer is mounted on hose usually using a kind of relatively simple fixture
On experimental rig, pressure test is then carried out.Pressure test tool is typically simple increasing apparatus, and cannot be efficiently controlled
Rate of pressure rise, there are security risks for pressure testing process.Since reviewer is installed to hose with fixture by craft, installation
It is easy to damage hose in the process；Meanwhile in hose clamp assembling and dissembling process, seal operation is finished artificially, it is difficult to be protected
Sealing performance when hose is mounted on verifying attachment is demonstrate,proved, be easy to cause in checkout procedure and the situation that inspection is unhappy, process is complicated occurs.
