Description
Technical field
The present invention relates to runner simulators, relate in particular to the runner simulation of a seed nucleus process pipe leak rate test
Device.
Background technology
Carry out LBB (Leak-Before-Break) analytical technology to need that pipeline crack slip model test to grind
Study carefully, carry out core process pipe leak rate test and need to simulate core grade pipeline crack runner, usually there is pipeline crack runner and basic
Two kinds of forms of runner.
In nuclear power plant's core process pipe leak rate test, runner simulator is connected to a bypass branch other than circuit
On the road, for simulating the crackle that the rupture of nuclear power station pressure pipeline generates, there is a situation where dielectric leakages.High-temperature, high pressure fluid passes through
Crackle is ejected into environment under low pressure outward, rapid pressure drop when fluid passes through crackle, is crossed when cold fluid flows in crackle and is sent out
Raw flass is changed into the state of heating power and dynamic instability between gas-liquid two-phase by single phase.And Study of Fluid temperature, pressure
Fluid temperature (F.T.), the pressure that flass is required in fracture in influence of the power to leakage rate, and test crack measure,
This in practical duct test be difficult to realize, need by can connect the runner simulator of pressure, temperature measuring instrument come
Simulate pipe leakage.Currently, the runner simulator used in leak rate test generally has following characteristics：(1) crack opening position
Shifting is decided when being processed by initial testpieces；(2) by simulation fracture runner side allowance weld, by flow path bodies material
It is welded to one；(3) runner inside surface roughness can be prefabricated；(4) flow channel entry point shape is there are many form, including rectangle, ellipse
Circle etc..
But there are following some drawbacks for existing runner simulator：(1) simulation fracture runner side allowance weld,
Flow path bodies material is welded together using welding form, can cause high-temperature, high pressure fluid that simulation fracture runner side is caused to stitch
Flow channel shape changes caused by gap is opened.(2) side being welded to connect generally is used in these schemes, between flow path bodies
Formula, but during weldering, high temperature may change the geometric shape inside runner, influence finally obtained test data
Confidence level；(3) and due to using welding, the runner gap length of each runner simulator, that is, the crack opening displacement simulated
(COD), it is fixed, it is meant that if there is the runner requirement of multiple and different sizes in content of the test, it is necessary to prepare multiple
Runner simulator, and cannot reuse, considerably increase testpieces manufacturing cost and human cost；(4) in some cracks
In modeling scheme, contact point of the flow path bodies in addition to welding position does not do special processing, these positions are in high temperature and pressure
It may occur that original contact cannot be kept in environment, cause the change of runner geometry, or even leak, cause entirely to let out
The failure of leak rate experiment.
Invention content
In view of the above-mentioned problems, the purpose of the present invention is to provide the simulations of the runner of a seed nucleus process pipe leak rate test to fill
It sets, to solve the problems, such as that flow channel shape changes caused by high-temperature, high pressure fluid causes simulation fracture runner side slit to open；
Solve the problems, such as that the opening displacement of simulation fracture runner cannot be adjusted.
To achieve the goals above, technical scheme is as follows：
The runner simulator of core process pipe leak rate test, which is characterized in that including the first body assembly of runner and
The second body assembly of runner is provided between the second body assembly of the first body assembly of runner and runner and is sandwiched in runner first
Two gaskets between the second body assembly of body assembly and runner, the gasket is by the first body assembly of runner and runner
Two body assemblies are formed separately a closed-gap, and the gasket blocks the side in the gap, described two gaskets with
The first body assembly of runner and the second body assembly of runner surround a simulation fracture runner, the first body assembly of the runner jointly
