Preferably: described draft tube is divided into draft tube A and draft tube B.By being provided with two draft tube, different draft tube can be selected according to dissimilar gas supply.Such as, the test gas being in gas phase completely connects draft tube A, and the test gas being in liquid phase connects draft tube B.Avoid influencing each other between the residual gas of situation two type of a shared draft tube.
Preferably: described retaining valve is respectively the one-level retaining valve and two-stage unidirectional valve that are connected successively.By two-stage retaining valve, can well avoid producing pressure or Mars and entering into and detect gas cylinder firing in process, avoid blast.
Preferably: described pressure transducer is connected with tensimeter.Be convenient to the pressure in observation and explosion-proof airtight container by tensimeter, the phase is if any pressure anomaly before operation, can shutdown system immediately, overhauls.
Preferably: bottom described Explosion-Proof Tank, be provided with heavy burden base.The center of gravity of whole explosion-protection equipment can reduce by heavy burden base, improves the stability fired in process, improves security performance further.
The beneficial effects of the utility model are: the utility model is by independently arranging explosive-proof sealed container and electric heater, explosive-proof sealed container is provided with gland bonnet, electric heater is connected with Explosion-Proof Tank and is provided with upper cover plate, not only increase overall sealing property, and be convenient to explosive-proof sealed container to take off, carry out comprehensive maintenance job.Maintenance job, for extremely important this device, because this device is to fire great pressure in process very large on whole equipment impact, therefore needs often to keep in repair, to ensure the security of this equipment, avoids blasting.
