Description
Technical field
Radioactive instrument technology is the utility model is related to, is supervised more particularly to a kind of online fluid radiation for nuclear power station
Survey the technology of instrument.
Background technology
Online γ fluid radiations monitor is widely used in AP/CAP series nuclear power station stationary radiation monitoring systems to replace
Add the off-line type fluid radiation monitor in the design of nuclear power station radiation monitoring system for conventional two generation and two generations.Online γ liquid prison
Instrument is surveyed because the relative off-line monitoring instrument of its measuring loop eliminates sampling pump, volume control device and electric control box etc., significantly
The composition of monitor is simplified, improves the response time of measuring loop；Simultaneously erecting bed space-consuming and can safeguard
Spatially require also to reduce compared with off-line type；Therefore online gamma radiation monitoring instrument has certain engineering practice advantage.But in length
In phase running, deposition of the radioactive substance in sampling container, also inevitably become online monitor needs
The problem of emphasis considers and prevented, and the design of existing sampling container is unreasonable, and detection efficient is relatively low.
The content of the invention
For defect present in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of energy
The effective residual activity material removed in sampling container, avoids radioactive substance from being deposited in sampling container, and detects effect
The high online fluid radiation monitor for nuclear power station of rate.
In order to solve the above-mentioned technical problem, a kind of online fluid radiation for nuclear power station provided by the utility model is supervised
Survey instrument, it is characterised in that：Sampling container, radiation detector, purge valve, blowoff valve including lead matter；
The top of the sampling container is fixed with sampling inlet tube, sampling outlet pipe, and the bottom of sampling container offers clearly
Mouth, sewage draining exit are washed, Radiation monitoring mouth is offered at the top of sampling container, the Radiation monitoring mouth is in radial contraction from the bottom to top
Tubaeform, the radiation detector is plugged in the Radiation monitoring mouth of sampling container；
The delivery port of the purge valve is connected to the Butterworth Hatch of sampling container by a cleaning pipe, and is connected to by an isocon
Inlet tube is sampled, the water inlet of the blowoff valve is connected to the sewage draining exit of sampling container by a blow-off pipe.
Online fluid radiation monitor provided by the utility model for nuclear power station, by cleaning pipe, isocon and row
The cooperation of dirty pipe, three-dimensional cleaning can be implemented to sampling container inside, can effectively remove the residual activity thing in sampling container
Matter, radioactive substance is avoided to be deposited in sampling container, and tubaeform Radiation monitoring mouth adds sampling container indirectly
Volume, detection efficient can be improved.
Brief description of the drawings
Fig. 1 is the structural representation of the online fluid radiation monitor for nuclear power station of the utility model embodiment.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with brief description of the drawings, but the present embodiment and not had to
It is every to use similar structure of the present utility model and its similar change in limitation the utility model, the utility model all should be included in
Protection domain, the pause mark in the utility model represents the relation of sum.
As shown in figure 1, a kind of online fluid radiation monitor for nuclear power station that the utility model embodiment is provided,
It is characterized in that：Sampling container 1, radiation detector 2, purge valve 5, blowoff valve 6 including lead matter；
The top of the sampling container 1 is fixed with sampling inlet tube 3, sampling outlet pipe 4, and the bottom of sampling container 1 opens up
There are Butterworth Hatch, sewage draining exit, the top of sampling container 1 offers Radiation monitoring mouth 11, and the Radiation monitoring mouth 11 is in from the bottom to top
Radial contraction it is tubaeform, the radiation detector 2 is plugged in the Radiation monitoring mouth of sampling container；
The delivery port of the purge valve 5 is connected to the Butterworth Hatch of sampling container 1 by a cleaning pipe 7, and passes through an isocon 9
Sampling inlet tube 3 is connected to, the water inlet of the blowoff valve 6 is connected to the sewage draining exit of sampling container 1 by a blow-off pipe 8.
The utility model embodiment is applied to detection radioactive substance conveyance conduit, will sampling inlet tube 3, sampling during use
Outlet 4 accesses tested pipeline so that and medium in tested pipeline enters sampling container by sampling inlet tube 3, then from sampling
Outlet 4 is discharged, and radiation detection, the Radiation monitoring mouth of sampling container can be carried out to the medium of sampling container using radiation detector
Designed using inside trumpet shape, add detection three-dimensional viewpoin of the radiation detector to sample, improve detection efficient.Need to sampling
When container is cleaned, first the measured medium in sampling container is emptied, rinse water is then introduced by purge valve, rinse water is led to
Over cleaning pipe 7, isocon 9, from two up and down of sampling container injection sampling container inner chamber, realize and sampling container inner chamber is stood
Body is cleaned, and the sewage after having cleaned is discharged by blowoff valve.
