The quick completion device of the airtight test disclosed by the utility model solves a problem that the airtight test takes too much time, and satisfies the needs of huge production devices.
Description
Technical field
The utility model relates generally to airtight experimental provision field, relate in particular to a kind of device of finishing tightness test fast, the needs that are mainly used in fields such as petrochemical complex, chemical industry are regularly opened the pressure vessel of functions such as drying, cooling, mixing and chemical reaction of particle of higher, inflammable and explosive or solid, the gas-solid state under the poisonous medium working condition of jar pressure that checks or the leakage check on the equipment.
Background technology
At present, pressure vessel relates to when often opening jar operating mode, system is carried out air-tight test closing a jar back usually, so that the sealing of assurance device.But being carried out air-tight test, system needs long time and the bigger equipments such as gas compressor of specification usually, particularly all the more so for the equipment under the high pressure operating mode.
When pressure vessel needs the open and close jar, the adapter mouth of main dismounting is also few, generally be concentrate on as: check and locate with manhole, discharge port etc., and other most mouths of pipe are not dismantled, also do not need to carry out leak check, so present technique can provide the measure that solves this difficult problem.
Progress along with the reach of science and industrialization technology; the container that requires to work under operating modes such as high pressure, high temperature in many industrial circles such as vapometallurgy regular meeting is regular loading and unloading material open and close jar, and therefore Sealing Technology of the present utility model has the prospect of using widely at a lot of industrial circles of China.
The utility model content
The utility model needs to carry out long leak check consuming time after at pressure vessel open and close jar and needs to be equipped with the difficult problem of expensive gas compressing equipment, and a kind of device of finishing tightness test fast is provided.
The utility model is achieved through the following technical solutions:
A kind of device of finishing tightness test fast is characterized in that: include piston type blind flange, flexible sealing element, adapter mouth spare, described piston type blind flange includes lid and the piston of integrative-structure, and the outer wall of piston inwardly is provided with ring-shaped groove; A described adapter mouthful part includes body, and the upper and lower end of body is respectively equipped with the outer, and the piston of piston type blind flange inserts in the body of interface pipe fitting, and embedding in the ring-shaped groove on the piston has flexible sealing element.
Described a kind of device of finishing tightness test fast is characterized in that: described flexible sealing element adopts O type ring or C type ring.
Described a kind of device of finishing tightness test fast, it is characterized in that: have through hole on the outer of the upper and lower end of the lid of described piston type blind flange, interface pipe fitting, lead to the hole site on the lid of the through hole of the outer of the upper end of interface pipe fitting and piston type blind flange is corresponding and fix by bolt-through, forms interface pipe fitting top inner chamber and as the air-tight test cavity; The through hole of the outer of the lower end of interface pipe fitting is corresponding with lead to the hole site on the pressure vessel to be measured and fix by bolt-through.
Described a kind of device of finishing tightness test fast, it is characterized in that: the piston diameter of described piston type blind flange is smaller or equal to 600mm.
Principle of the present utility model is:
By aperture (as inspection hole, manhole or the discharge port) installation that need often open at pressure vessel device of the present utility model is set, it is a kind of seal assembly that is constituted by piston type blind flange, flexible sealing element and adapter mouth spare, can finish the airtight check test of pressure vessel fast, both can reduce the airtight check test time, can reduce experimentation cost again, reach target safe and reliable to operation, economical rationality.
The piston cavity of piston type blind flange has constituted pressure chamber, and in airtight check test, this pressure chamber can replace the actual cavity of whole pressure vessel, thereby realizes replacing with little volume the function of big volume.
Device of the present utility model can be effectively under-100～260 ℃, 10MPa working condition, piston cavity and pressure vessel inner chamber are isolated, realize with little tolerance finish atm number the effect of the sealing surface that should check.
A kind of piston type blind flange of installation is set in order to substitute original common blind flange by the dismounting mouth at pressure vessel, utilizes the flexible seals of its piston outer rim that flange face and container intracavity are isolated.When the dismounting of the aperture of pressure vessel is opened blind flange, and adopt the piston type blind flange to seal installation again after, detect as long as piston cavity is carried out pressurising, can realize the tightness test to pressure vessel.Because the piston cavity volume is very little, so it is very short to finish the time of tightness test, thereby can realize finishing fast the purpose of tightness test.
The utility model has the advantages that:
The tightness test device that the utility model can be finished fast to solve air-tight test long problem consuming time, satisfies the needs of large production equipment.
