Abstract
The invention discloses a civil defense door airtightness detection apparatus with a protection function. The apparatus comprises a casing, an air conveying apparatus communicating with the back surface of the casing, and an air adjusting apparatus. The back surface of the casing is provided with a rectangular opening, the rectangular opening is provided with a door body to be detected, a communicating pipeline between the air conveying apparatus and the casing is internally provided with a pressure adjusting valve, the air adjusting apparatus comprises a pressure transmitter, the pressure signal port of the pressure transmitter communicates with the casing, and electric signals are connected with the controlled end of the pressure adjusting valve through the pressure adjusting apparatus; and the lower end of the casing is provided with a mobile track, and the back surface of the casing is provided with a water tank. According to the invention, an airtight door installed on the casing carries out an air conveying step, at the same time, through cooperation with the air adjusting apparatus, when set test pressure is reached, the quantity of air passing through a gas meter within certain time is read, then an air leakage rate in case that airtight door is under a standard condition is calculated by use of a physical formula; and for the purpose of facilitating observation, the door body to be detected and one end of the casing are placed in water so that airtightness is conveniently observed.
Description
Technical field
The present invention relates to a body airtight detecting apparatus technical field, specifically belong to a kind of with safeguard function closed guard gate air-tightness detection device.
Background technology
For ensureing the normal operation of nuclear power station unit, China all needs just can come into operation through strictly detecting to the impermeability of gas-tight door at the nuclear power station built at present, but the nuclear power station that early stage builds, its supporting gas-tight door carries out all abroad by its corresponding tightness test of external import, for the nuclear power air tight door tightness test project domesticized, the air-tightness of production domesticization gas-tight door is checked whether to meet nuclear power designing requirement, the air tightness tester technology matched with it, especially about constant voltage pick-up unit technology or blank, and not yet there is the device being suitable for gas-tight door air-tight test in the domestic inspection body authorized through country at present, therefore a kind of test unit being applicable to domestic gas-tight door is badly in need of.
Summary of the invention
For the problems referred to above, the object of this invention is to provide one with safeguard function closed guard gate air-tightness detection device, overcome the deficiencies in the prior art, simplicity of design, rational in infrastructure, the gas-tight door be arranged on casing carries out air supplying step, coordinate conditioner simultaneously, when reaching setting test pressure, read gas meter within a certain period of time by the amount of air, recycling physical equation calculates the air leak rate under gas-tight door mark condition; For convenience of observing, door body to be detected and casing one end being placed in water simultaneously, being convenient to observation airtight.
The technical solution used in the present invention is as follows:
A kind of with safeguard function closed guard gate air-tightness detection device, comprise casing, the air transport device be communicated with the back side of casing and conditioner, rectangular aperture is provided with after described casing, described rectangular aperture place settles door body to be detected, pressure-regulating valve is provided with in described air transport device and described casing connecting pipeline, described conditioner comprises pressure unit, the pressure signal port of described pressure unit is communicated with casing, and its electric signal end connects the controlled end of described pressure-regulating valve by pressure governor; Casing lower end is provided with moving track, is provided with tank after described casing, is provided with transverse bar and longitudinal rod after described casing.
