Specific embodiment
The technical solution of the utility model is described in detail combined with specific embodiments below, so that art technology
Personnel more fully understand the utility model and are practiced.
Please refer to attached drawing 1, a kind of controllable temperature sealing device, including cover 11, circulating pump 3, screen pipe 7, blank pipe 12, circulation
The main components such as gas heating temperature control means 9 are wherein opened up on cover 11 there are three interface, and the first interface 1 is examined for mark-on
It surveys, the second interface 2 is used for piping connection circulating pump 3, and circulating pump 3 connects triple valve 4, and circulation is logical in the connection of 4 one end of triple valve
Road, for connecting external equipment 5, external equipment 5 can be for example portable GC of test equipment and can also be not connected to test to be set the other end
It is standby to be only used for VOCs on-site collection (because external equipment 5 is not the required component of the present apparatus, so pipeline is represented by dashed line in Fig. 1
Connection relationship).Third interface 10 is used for the circulating air heating temperature control means 9 of piping connection circulation passage.
The inner loop pipeline specifically includes screen pipe 7, blank pipe 12 and circulating air heating temperature control means 9, wherein screen pipe 7
By 6 piping connection circulating pump 3 of triple valve, the other end is heated by 8 piping connection circulating air of triple valve for one end with blank pipe 12
Temperature control device 9, the third interface 10 on 9 piping connection cover of circulating air heating temperature control means.
The triple valve 6 that screen pipe 7 and blank pipe 8 connect 3 one end of circulating pump control screen pipe 7 and blank pipe 8 be separately turned on and
It closes, gas circuit can be adjusted by control valve, switched in test mode and background clearance state.
