Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 show the structural schematic diagram of traditional two section type rubber film sealed dry type gas chamber, generally, cabinet body packet
Cabinet floor 1, cabinet top plate 5 and side plate 3 are included, is equipped with piston 7 and T baffle 8 in cabinet body, piston 7 and T baffle 8 can be in cabinet bodies
It is up and down；During the operation of the gas tank, pass through the discrepancy of piston 7 and T baffle 8 moved up and down to realize coal gas, T gear
When plate 8 is not contacted with piston 7, by 2 support of T shutter carrier, piston 7 rises to contacted with T baffle 8 after, T baffle 8 can be held up
Extremely separated with T shutter carrier 2；During piston 7 and T baffle 8 are up and down, there is rubber membrane 9 that can guarantee the sealing of cabinet body.
Applicant passes through the study found that the gas pressure of downstream process feedback is due to T baffle 8 and piston the case where fluctuation
There is contact between 7 leads in cabinet body that there are the switchings of two kinds of pressure with two states are separated, when 7 independent buoyance lift of piston,
Coal gas is first class pressure, and when piston 7 contacts T baffle 8 and buoyance lift together, coal gas is secondary pressure, and secondary pressure is than one
Stage pressure is about higher by 0.6~0.7kPa.This pressure change is in previous relatively rough production in gas operating condition and gas pipe
Belong to the factor often ignored in network pressure power management, especially in the case where gas chamber output coal gas air pressure is relatively high；And
Under the requirement of Gas In Iron And Steel Works ductwork pressure fine-grained management, the variation of this pressure is then unacceptable, after coal gas
Continuous processing or directly application will cause adverse effect.Therefore, applicant studies this and proposes solution.
