Abstract
The utility model discloses a kind of transmitter enclosure with radiation-resisting functional, including outer cover body and screen layer, outer cover body includes that housing and lid, lid are connected in the top of housing, and in order to sealing shell body, screen layer is on the inwall of outer cover body.This utility model reduces the irradiation suffered by internal electronic component, improves the overall resistance to irradiation ability of transmitter, more improves accuracy of the transmitter under high accumulated dose irradiation, enable in particular to ensure use function of the transmitter under nuclear power plant accident state.
Description
Technical field
This utility model is related to transmitter technology, more particularly, it relates to outside a kind of transmitter with radiation-resisting functional
Shell.
Background technology
Extensive application is automatically controlled in modern industry production process.Automatic control system is mainly by controlled plant, detector
Table, adjusting means and actuator etc. are constituted.The controlled variable of reflection controlled plant characteristic is felt simultaneously by instrumentation
Standard Gases signal or the signal of telecommunication is converted into, is then compared with the set-point of given device, produced deviation signal is acted on
In governor motion, governor motion acts on controlled plant by a certain predetermined rule by recording a demerit, and is adjusted by increasing or reducing
Medium is so as to affect the change of controlled variable, until controlled variable is reduced or eliminated with the deviation of set-point.
Transmitter (generally including the parts such as sensor and transducer) belongs to instrumentation, it by various technological parameters such as：
The physical quantitys such as temperature, pressure, flow, liquid level, density and composition are converted into signal of seeking unity of standard accordingly, then pass to distant place control
The arithmetical unit of room, actuator, display instrument etc., to be adjusted, indicating and recording to being conditioned parameter.
Existing used transmitter enclosure, is typically all made using stainless steel, is directly put inside the housing
The electronic devices and components of transmitter are put, in routine work use, under the irradiation of high irradiation dose, the electronic devices and components of inside the shell
Performance is easy for changing, so as to cause the accuracy performance of transmitter drastically to decline, in order to safeguard work can be normal
Running, also needs the transmitter for more renewing up, increased production cost, while also increasing the workload of personnel.
Utility model content
For defect present in above-mentioned prior art, the purpose of this utility model is to provide a kind of with radiation-resisting functional
Transmitter enclosure, it is possible to increase class of accuracy of the transmitter under high irradiation dose irradiation, ensured the use of transmitter
Function.
For achieving the above object, this utility model is adopted the following technical scheme that：
A kind of transmitter enclosure with radiation-resisting functional, including outer cover body and screen layer, outer cover body includes housing
And lid, lid is connected in the top of housing, and in order to sealing shell body, screen layer is on the inwall of outer cover body.
Described outer cover body is made up of stainless steel.
Described screen layer is made up of tungsten nickel material.
The through hole in order to connection line is further opened with the bottom of described housing.
In above-mentioned technical proposal, this utility model is closed using the strong tungsten nickel of stainless steel casing body liner radiation protection ability
Gold makees Flouride-resistani acid phesphatase screen layer, reduces the irradiation suffered by internal electronic component, improves the energy of resistance to irradiation of pressure transmitter
Power.
Description of the drawings
Fig. 1 is the schematic diagram of this utility model structure.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1, a kind of transmitter enclosure with radiation-resisting functional provided by the utility model, including outer
Shell body 1 and screen layer 2, outer cover body 1 include that housing 101 and lid 102, lid 102 are connected in the top of housing 101, in order to
Sealing shell body 1, screen layer 2 is on the inwall of outer cover body 1 so that screen layer 1 surrounds internal transmitter 3 completely
Electronic devices and components, to reduce the irradiation suffered by electronic devices and components, so that improve the resistance to irradiation ability of transmitter.
Preferably, described outer cover body 1 is made up of stainless steel, because the outer cover body of stainless steel 1 can
So that the transmitter of inside has corrosion-resistant and chemical spray characteristic.
Preferably, described screen layer 2 is made up of tungsten nickel material, because tungsten nickel material has radiation protection ability
By force, the characteristic that in addition also has that mechanical performance is strong, plasticity is strong, comprcssive strength is big etc., nontoxic and be not that potential mixing is dangerous useless
Thing.
Preferably, the through hole 4 in order to connection line on the bottom of described housing 101, is further opened with, the big I of through hole 4
Change according to the circuit needed for transmitter 3.
In sum, this utility model makees anti-spoke using the strong tungsten nickel of stainless steel casing body liner radiation protection ability
According to screen layer, the irradiation suffered by internal electronic component is reduced, improve the resistance to irradiation ability of pressure transmitter.And this
Utility model is more suitable for the core stage pressure transmitter that used in nuclear power station, improves core stage pressure transmitter in high accumulation agent
Class of accuracy under amount irradiation.
Those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to illustrate that this practicality is new
Type, and be not used as be to restriction of the present utility model, if in spirit of the present utility model, to the above
The change of embodiment, modification will all fall in Claims scope of the present utility model.
