Abstract
The utility model discloses a structure of a nuclear safety temperature transmitter, which is characterized in that one end of a seal metal flexible pipe is connected with a shell cover through a waterproof connector, the other end of the seal metal flexible pipe is connected with a device through the waterproof connector, a lead-out wire in a meter is led out through a seal metal flexible pipe, and peculiar sphere seal design of the end part of the waterproof connector causes the meter to have good sealability, high pressure resistance, high temperature resistance and high humidity resistance. Fixing holes and electronic circuit boards at the periphery of a casing body are packed by unique silica gel. The meter has good shock resistant performance, and the utility model is suitable for occasions with adverse operating mode conditions, such as a nuclear power plant, etc.
Description
Technical field
The utility model belongs to the temperature measuring instrument technical field, is specifically related to be applicable to the temperature transmitter of rugged surroundings such as nuclear power station, and the temperature signal of object in situ is converted to standard signal, is used for system automation control.
Background technology
The nuclear power station working condition is very harsh, the maximal work environment temperature is up to 160 ℃, and requires instrument to satisfy specific (special) requirements such as heat ageing, antiseismic, anti-irradiation, under the nuclear power station harsh conditions, instrument stable and reliable for performance plays crucial effects to the normal operation of nuclear power station.But existing temperature transmitter general work environment temperature only is 0-70 ℃, can not satisfy requirements such as thump that anti-irradiation, antiseismic or loss of-coolant accident (LOCA) etc. cause, high temperature resistance, high pressure.
Summary of the invention
The purpose of this utility model is: a kind of harsh working condition of nuclear power station, reliable temperature transmitter of high safety of being applicable to is provided.
For achieving the above object, the technical scheme that adopts is: the nuclear safe level temperature transmitter, comprise housing, shell, place electronic circuit board, connection terminal between housing and the cap, its characteristics are: sealed metal hose one end links to each other with cap by water joint, place the water joint and the equipment of the described sealed metal hose other end to join, the extension line of connection terminal is drawn by described sealed metal hose.
There is the ball-type joint of an evagination end of water joint, and there is a concavity sphere cap upper end, and described ball-type joint and sphere fit tightly by the securing member hexagonal nut.
Be equipped with O-ring seal between housing and the cap.The housing periphery is equipped with fixed orifice, is used for metope being installed or being pacified the frame dress and fix.Electronic circuit is encapsulated by special silica gel.
Good effect of the present utility model is: extension line is drawn by sealed metal hose, and the ball face sealing unique design of water joint is equipped with O-ring seal between housing and the cap, makes the instrument good airproof performance, and high temperature resistant, high pressure resistant, humidity, anti-radiation performance are good; The housing periphery is equipped with fixed orifice, is used for temperature transmitter is fixedly installed in metope or is fixed on erecting frame; Electronic circuit board is installed with special silica gel sealing, makes temperature transmitter that better anti-seismic performance be arranged.
