Abstract
The utility model discloses a shell body structure of an electronic part of a nuclear safety class capacitance type differential pressure transmitter, which is characterized in that the utility model is only provided with one leading wire interface which is designed into a taper pipe thread interface, the interface is connected with a cable joint directly, and the nuclear radiation resistance and the sealing performance of a chamber are improved, causing electronic elements to resist a 6*10< 5 >Gy irradiation requirement. Unique double sealing ring seal design of a zero adjustment rod causes the steam, high-temperature and high-pressure resistance and the chemical spray performance of the transmitter to satisfy the requirements of a nuclear power plant.
Description
Technical field
The utility model belongs to the industrial automation instrument technical field, is specifically related to the capacitance differential pressure cell that the abominable occasion of environmental baseline such as nuclear power station is used.
Background technology
The nuclear power station working condition is very abominable, the maximal work environment temperature is up to 160 ℃, and require instrument to satisfy requirements such as anti-irradiation, antiseismic, anti-steam High Temperature High Pressure, but common capacitance differential pressure cell only is applicable to the general work environment, environment temperature only is 0-70 ℃, transmitter cisco unity malfunction under 6*105Gy irradiation, under steam high temperature, condition of high voltage, the sealing property of housing and adjusting zero rod is difficult to guarantee.
Summary of the invention
The purpose of this utility model is: provide a kind of suitable nuclear power station to use the capacitance differential pressure cell of anti-irradiation, anti-steam high temperature and high pressure.
For achieving the above object, the technical scheme that adopts is: the nuclear safe level capacitance differential pressure cell, comprise lid, electronic cartridge, be fixed on the wiring board in the electronic cartridge, it is characterized in that: adjusting zero rod and lead-in wire interface are positioned at the side of electronic cartridge, and described adjusting zero rod is vertical mutually with the axis direction of lead-in wire interface.
Described lead-in wire interface is the taper-thread interface, and quantity is 1.Be equipped with two O-ring seals between adjusting zero rod and the electronic cartridge, adopt double density seal sealing.
The beneficial effects of the utility model are: the lead-in wire Interface design becomes the taper-thread interface, can directly be connected with cable splice, and have only an interface, and the double density seal design of adjusting zero rod uniqueness has improved the ability and the sealing property of the anti-nuclear radiation of instrument.
