Description
Technical field
The present invention relates to a kind of nuclear power valve earthquake simulation detection means.
Background technology
Valve is control unit in pipeline fluid induction system, for changing path section and media flow direction, is had
The functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.Because the purposes of valve is extensive, therefore it is in pipeline
Middle role is also very big.It is again bearing device and core valve is not only system control and adjusting means, its ruuning situation is closed
Fault Control and the safe operation of reactor are tied to, its importance is well imagined.According to the International Atomic Energy Agency to nuclear safety thing
Therefore statistics, because the nuclear safety accident that valve leaks cause accounts for larger proportion in all accidents, so core valve must be paid attention to
Security reliability.Wherein, harm of the earthquake to nuclear power valve can not be ignored.Punching is caused on table ground over the ground for well-known earthquake
The injury of hitting property, the shock resistance of the such nuclear power valve major criterion for being to weigh valve security performance whether up to standard.At present
China is few and all more complicated for the anti-seismic detection device of valve, is taken time and effort in detection, and simulation
Direction of vibration is not also comprehensive, and applicable valve is also relatively simple.Apparatus of the present invention purpose is the focus for simulating different directions, and
And suitable for the valve of different size, easy to operate, install convenient.
The content of the invention
The present invention provides a kind of nuclear power valve earthquake simulation detection means.
Basic technical scheme is：Valve earthquake simulation detection means is by base, connector, connecting pipe, vibration detection dress
Put, magnetite, electromagnet composition.Base is made up of hollow steel plate, and sandy soil are inserted in the inside, and steel plate has certain mass, plays fixed dress
That puts acts on and ensures that detection means has certain free degree, and sandy soil can imitate the actual state of geology.Base upper band
There is the support base of connecting pipe, connector is installed on pipeline, the valve for connecting different size.Under valve installation site
Side is equipped with vibration detection device, detects the antidetonation situation of valve and can read data.Base side is equipped with vibration generating arrangement,
Device is divided into two groups, and horizontal and vertical vibration is produced respectively.Every group of two electromagnet are staggered relatively, and centre spring fixes one
Two electromagnet interactions are powered so that magnetite vibration drives whole device by magnetite.
The beneficial effects of the invention are as follows：
1. the present invention is made of hollow steel plate, reduces cost of manufacture, alleviates quality, convenient operation.
2. sandy soil are filled with the hollow steel plate that the present invention is used, the position with tube contacts is directly exposed to, more very
The real situation for simulating the vibration of earthquake sandy soil.
3. the present invention uses a kind of replaceable Fast Installation connector connecting valve and pipeline so that apparatus of the present invention are applicable
In multiple interfaces valve such as flange, screw thread, welding etc., and can Fast Installation valve to be detected.
4. the present invention uses electromagnetic oscillation device, electromagnet interaction is powered according to magnetic principles is mutually repelled with magnetite, makes
Magnetite cyclic movement, so that device produces vibration, by pipeline band moving valve, reaches the mesh of detection valve body anti-seismic performance

Degree, sandy soil can imitate the actual state of geology.Base（1）It is upper to carry connecting pipe（3）Support base, pipeline（3）Upper installation
Connector（2）, the valve for connecting different size（7）.In valve（7）The lower section of installation site is equipped with vibration detection device
（4）, detect valve（7）Antidetonation situation and data can be read.Base（1）Side is equipped with vibration generating arrangement, and device is divided into
Two groups, horizontal and vertical vibration is produced respectively.Every group of two electromagnet（6）Staggered relatively, centre spring fixes a magnetic
Stone（5）, to two electromagnet（6）Interaction is powered so that magnetite（5）Vibration drives whole device.
The course of work of the present invention is as follows：
During work, by valve body to be measured（7）By connector（2）Access the connecting pipe of detection means（3）In, base（1）Interior inspection
Survey the power supply of device, connector（2）Make valve to be measured using electromagnetic principle equipped with calutron（7）Rapid alignment connector is simultaneously filled
Tightly, connector（2）Can be according to valve to be measured（7）Model difference carries out supporting replacing.Base（1）Have adjustable in interior detection means
The power supply of electric current, according to detection need regulation detection means in electromagnet（6）The size of current of access.According to magnetic principles to electricity
