Technical field
The utility model belongs to the impulse generator technical field, is specifically related to a kind of pulse generation system that is used for the radioactivity place.
Background technology
The using gases pulse of radioactivity place is made up of a pulse valve, an intake valve and an air bleeding valve the pulse generation system of extraction equipment (like pulse extraction post, mixer-settler) when playing pulse usually.Pulse valve need be installed in the good glove box of shielding.The rotation of pulse valve periodically gets in the extraction equipment Compressed Gas in the pressure surge tank, and the gas in the extraction equipment is periodically discharged.Intake valve should be opened during the extraction equipment operate as normal, and air bleeding valve should be closed.When the pulse valve fault, when stuck, air bleeding valve should be opened, and intake valve should cut out.The design of pulse generation system should be guaranteed system stability and less trouble, and easy access.
Existing pulse generation system is prone to following fault: 1) magnetic valve when work, the heating of valve interior loop, temperature is higher, magnetic valve breaks down easily; 2) in case pulse valve breaks down can not run well, and the valve block position just in time stops to the position of air inlet in post, and material will be ejected from capital by air-flow in this moment pulsed column, and magnetic valve does not have switch indication or signal feedback, and fault can not in time be found; 3) even find fault, because the maintenance magnetic valve is not easy to operate in glove box, fault can not get quick solution.
Summary of the invention
The purpose of the utility model is to solve the problem that the prior art fault rate is high, be difficult to overhaul, and a kind of pulse generation system that is used for the radioactivity place is provided.
The utility model is achieved in that
A kind of pulse generation system that is used for the radioactivity place comprises glove box, pulse valve, exhaust pneumatic operated valve, air inlet pneumatic operated valve, pulse valve spool rotation speed monitor, vacuum tank, drive link and motor; Wherein, have through hole on the glove box 1; The spool of pulse valve is connected with an end of steel drive link, and the air inlet of pulse valve is connected with the output of air inlet pneumatic operated valve, and the gas outlet of pulse valve is connected with gas exhaust piping with pulsed column, and pulse valve is installed in glove box inside; Motor is installed in the glove box outside, and the rotor of motor is connected with the other end of drive link; Drive link passes glove box, connects pulse valve spool and rotor; The input of air inlet pneumatic operated valve is connected with the outlet of vacuum tank; The input of exhaust pneumatic operated valve links to each other with the outlet of vacuum tank, and the output of exhaust pneumatic operated valve is connected with gas exhaust piping; Pulse valve spool rotation speed monitor is installed on the pulse valve.
The beneficial effect of the utility model is:
