Description
Technical field
The utility model is related to self-rescuer detection device field, specifically a kind of self-rescuer general safety air tight test dress
It sets.
Background technology
Self-rescuer is mine staff have been prevented when fire, gas, coal-dust explosion, coal and gas prominent occur for underground
A kind of portable respiratory protection utensil of evil gassing or anoxia asphyxia.Self-rescuer needs to inspect periodically whole air-tightness
Whether good, airtight undesirable self-rescuer is forbidden to use.The whole air-leakage test of self-rescuer is observed using hydraulic pressure at present
Self-rescuer to be measured is put into and measures in tank by method, and the one end for measuring tank is connect with vertical transparent water pipe, will measure after potting is closed and notes
Full water then passes to the gas of pressure, at this time the water surface in transparent water pipe will rise, it is static after a certain period of time, pass through observation
Water surface elevation in transparent water pipe changes to judge whether the air-tightness of self-rescuer meets the requirements.This air-leakage test mode exists
It also needs to dry self-rescuer to be measured after being measured, increases unnecessary work load, while this airtight detection mode is also deposited
In the low problem of accuracy.
Utility model content the purpose of this utility model is to provide a kind of self-rescuer general safety air tight test device,
It is low to need to be dried work, accuracy to solve the problems, such as prior art self-rescuer integrally existing for airtight detection.
In order to achieve the above object, technical solution used by the utility model is：
A kind of self-rescuer general safety air tight test device, it is characterised in that：Include the shell that top is faucal, shell
Mouthful top sealing cover conjunction is connected with head cover, and head cover, which is equipped with, to be led in shell and the inlet, outlet with airtight valve respectively, in shell
Bottom centre is equipped with boss, is the circumferential chamber for surrounding boss around boss, and boss center vertical is equipped with central through hole, central through hole
Lower end penetrates through housing bottom, and central through hole upper end is arranged in boss top surface and is shaped to expanding mouth, further includes support tube, support tube
For placing self-rescuer to be measured in pipe, support inside pipe wall is equipped with multi-turn sealing ring, by multi-turn sealing ring and self-rescuer side to be measured
Sealing is constituted, support tube lower end is coaxially connected with tube head, and tube head inner wall is equipped with for limiting and supporting self-rescuer bottom to be measured
Land, the support tube and boss central through hole upper end are coaxially connected, and the tube head of support tube lower end is coaxially assemblied in expanding mouth,
And elastic seal ring is equipped between expanding mouth inner wall and tube head outer wall, it is realized by elastic seal ring close between tube head and expanding mouth
Envelope, shell side is equipped with towards circumferential intracavitary and the entery and delivery port with airtight valve, shell are externally provided with vertical tubing string respectively, pipe
Column lower end is connected to by horizontal connecting tube with circumferential intracavitary.
A kind of self-rescuer general safety air tight test device, it is characterised in that：From interior between head cover and faucal
To multi-turn sealing ring is externally provided with, the sealing of head cover and faucal is made of multi-turn sealing ring.
A kind of self-rescuer general safety air tight test device, it is characterised in that：Detection shell is additionally provided on head cover
The pressure gauge of internal air pressure.
A kind of self-rescuer general safety air tight test device, it is characterised in that：Around the circumferential chamber one of boss
Upper lateral part is equipped with connecting seat, is connected with guide post between connecting seat and housing bottom vertically, float, guide post are slidably fitted on guide post
The connecting seat of upper end is equipped with the pressure sensor coordinated with float.
A kind of self-rescuer general safety air tight test device, it is characterised in that：Float is equipped in the tubing string,
Float top surface is equipped with speculum, and upper end is equipped with LASER Discharge Tube and laser pick-off pipe in tubing string, and LASER Discharge Tube is to float top
Face speculum emits laser, and laser is received after speculum reflects by laser pick-off pipe.
A kind of self-rescuer general safety air tight test device, it is characterised in that：The support tube tube head inner wall
Land be equipped with elastic seal ring, be pressed on elastic seal ring by self-rescuer to be measured realize it is close between land and self-rescuer to be measured
Envelope.Compared with prior art, it is the advantages of the utility model：
Utility model works principle is：Self-rescuer to be measured is put into support tube, and self-rescuer to be measured is made to be pressed on branch
Sealing is constituted in land in stay tube tube head, is then integrally assembled support tube in boss central through hole upper end, the pipe of support tube
Sealing is constituted by elastic seal ring between head and the expanding mouth in central through hole upper end, is then filled in the circumferential chamber of boss
Then water is filled with gas into shell again, then water flows under gas pressure in tubing string, so that the float in tubing string is floated, gas
Stop inflation after being filled with a period of time, be conducive to the height change that laser measures pipe float, if float height change is more than default
Value, then show that self-rescuer to be measured air-tightness itself is poor, if float height change is less than preset value, shows self-rescuer sheet to be measured
Body air-tightness is preferable.
In the utility model, due to realizing that stringent sealing, support tube are logical with boss center between self-rescuer to be measured, support tube
Stringent sealing is realized between the expanding mouth in hole upper end, therefore gas only can just be arranged by self-rescuer to be measured out of shell in shell
Go out, if therefore self-rescuer poor air-tightness to be measured, air pressure change is big in shell, causes float height change in tubing string larger.
In the utility model, although being still that hydraulic pressure observation measures self-rescuer air-tightness to be measured, self-rescuer to be measured without
It must contact, therefore self-rescuer to be measured need not be dried after a measurement with water, and float height is measured to pipe using laser
Degree variation has the advantages that measurement accuracy and accuracy are high.
