Problems solved by technology

The optimal working pressure of AGIL is about 0.5KPA, if it is much higher than this pressure, the system will work unstable
At the same time, a dangerous situation will arise if a pressure higher than that to which the optical cavity is subjected

Abstract

The invention discloses a high pressure automatic pressure relieving system. The system comprises: a pressure transmitter; a pressure display instrument which is connected with a pressure vessel through the pressure transmitter; a feedback extraction circuit for receiving a feedback signal of the pressure display instrument; an on-off circuit which can be used to perform strong control on the output of the feedback extraction circuit; a drive circuit for receiving the signal of the feedback extraction circuit; and an electrically operated(pneumatic) valve, wherein the input of the valve is connected with the drive circuit, and the valve can be used to perform pressure relieving on the pressure vessel after being conducted. According to the invention, the on / off state of the valve is controlled through the pressure change in the pressure vessel, so once the pressure in the pressure vessel exceeds a set pressure, the automatic pressure relieving effect can be realized. Moreover, the system can be applied to other devices needing high pressure automatic pressure relieving. In addition, advantages, such as compact and small structure, low cost, safety, reliability, convenience, rapidity, etc., can be realized.

Description

technical field [0001] The invention relates to a laser equipment control system, in particular to a high-pressure automatic pressure relief system with feedback control. Background technique [0002] All gas-phase iodine laser (AGIL, all gas-phases iodine laser) is a new type of iodine laser based on NCl(a)-I energy transfer. Its technical route is as follows: [0003] F+DCl->DF+Cl [0004] Cl+HN 3 ->HCl+N 3 [0005] Cl+N 3 ->NCl(a)+N 2 [0006] NCl(a)+I->NCl(X)+I* [0007] I*+hv(1315nm)->I+2hv(1315nm) [0008] From the 1990s to the present, AGIL has gone through the research stages of conception, pulsed light output, continuous flow gain test of the discharge scheme, continuous flow light of the discharge scheme, preliminary amplification of the continuous flow of the discharge scheme, and combustion drive attempts. Fast progress. The optimal working pressure of AGIL is about 0.5KPA, if it is much higher than this pressure, the system will work uns...
