Description
Technical field
The invention belongs to flange seal technical fields, and in particular to a kind of sealing of power station water system vessel flange and detection mould
Quasi- device.
Background technique
In the water system overhaul of the equipments of power station, it usually can all be related to a large amount of flange seal work, flange arrangement form
It is related to prominent face flange, concave-convex flange, male-and-female flange.Flange seal belongs to a basis but highly important process, sealing effect
Fruit is affected by operator's level of skill, and in assembling process, points for attention are also not quite similar various forms of flanges.
For the pressure of power station water system usually within 2.5Mpa, flange quantity is more, at the scene in real work, often
It will appear more leakage.And studying carefully its leakaging cause is usually misoperation caused by personnel's level of skill is not high, such as gasket
It is not up to standard etc. not into, flange fastening deflection, the depth of parallelism to compress not in place, flange seam allowance.
Therefore in order to improve the quality of flange seal, it is necessary to carry out certain skills training to operator.Previous
Skills training is carried out by text, picture, case explanation, and personnel are only capable of carrying out memory understanding by the content that paper is explained, no
Enough intuitive, result of training is bad.Meanwhile Assessment is also only limitted to oral account or written examination, lacks preferable training and examination and practice
Platform.When trained personnel operate at the scene, often occur actual operational capacity shortcoming, technical essential operation it is lack of standardization,
Situations such as unskilled, it is easy to cause flange seal unqualified, flange is caused to leak.
Therefore it needs by means of certain to carry out simulated in situ method orchid seal operation to personnel, more from existing device or equipment
Good development skills training and assessment mode.
Summary of the invention

Described bracket one end and left side main pipeline is welded.
The bracket other end is fixedly connected with right side main pipeline by anchor ear, anchor ear fastening nut.
The frame bottom is fixed on the base.
The beneficial technical effect of the present invention lies in: water system vessel flange sealing in power station of the invention and test simulator
The flange seal operating platform at simulation scene can be provided for personnel, be provided simultaneously with the function of sealing effect detection.Simulator
Have three classes primary structure form flange: prominent face flange, male-and-female flange, concave-convex flange keep personnel close to different form flange
The technical ability of envelope is grasped comprehensively, and suppresses the external pressure pump boosting of interface, simulation system pressure, to personnel's by simulator
Flange seal effect is detected, and is exposed problem in time and is corrected, intense session effect, and it is close to promote fielded system maintenance rear flange
Seal qualification rate.In addition, being based on this simulator, personnel can carry out off-line verification to flange seal method, further increase close
The reliability of envelope.
