It is connect with external gas source；The detection unit includes three snorkels, check valve, gas gauge and seal cavity, the threeway
Three ends of tracheae are connected to the gas outlet of inlet suction port, gas gauge and seal cavity respectively, the check valve setting
The tracheae middle section of inlet suction port is connected in three snorkels, and the airflow direction of the check valve is from inlet suction port to threeway
At the threeway of tracheae.
Further, the seal cavity includes shell and openable and closable door body, and the junction of the door body and shell has
Sealing strip.
Further, the gaseous species of the external gas source are nitrogen or argon gas.
Further, the gas gauge is precision digital pressure gauge, vibration-proof pressure gauge or capsule pressure gauge.
Further, the material of three snorkel is EPDM, PU, NBR, PVC or SBR.
