A Cylinder Pressure Stability Control Device and Using Method

Abstract

A cylinder pressure stabilization control device and a use method thereof belong to the technical field of petroleum seismic exploration equipment. The fixed plate is connected to the cylinder top cover through 12 M16 mounting bolts, the gas cylinder air inlet joint is connected to the air intake port of the cylinder, the gas cylinder air intake joint is connected to the second transition joint through the first rubber hose, and the second transition joint is installed on the four On the manifold, the overflow valve, the first transition joint and the second transition joint are respectively installed on the four-way manifold, the shut-off valve is connected to the second transition joint, the one-way valve is connected to the fourth transition joint, and the second hose passes through The third transition joint is connected to the one-way valve, the outlet of the pressure reducing valve is connected to the second rubber hose, and the air inlet of the pressure reducing valve is connected to the nitrogen cylinder; the four-way manifold realizes the one-way valve, the cylinder air inlet joint, and the shut-off valve , Parallel connection of gas relief valve. The invention realizes the attenuation of the gas under the same pressure state, ensures the consistency of the attenuation of the gas pressure, and reduces the difference of the gas pressure between times.

Description

technical field [0001] The invention relates to a cylinder pressure stabilization control device and a use method, belonging to the technical field of petroleum seismic exploration equipment. Background technique [0002] At present, the heavy hammer pulse source at home and abroad mainly adopts the structure driven by cylinder compression energy storage, and its principle is as follows: figure 1 As shown. The nitrogen cylinder 2 serves as the inflation pressure source of the cylinder 5; the pre-charge gas pressure in the cylinder is controlled by the pressure reducing valve 3, which can realize different excitation energy requirements; the one-way valve 4 plays a protective role for the pressure reducing valve, and the stop valve 1 Used as an exhaust valve when the system needs to be maintained. [0003] Due to the instability of the compressed state of the gas and the influence of the work done by the gas on the weight on the state of the gas, the pressure of the gas chan...

AI Technical Summary

Problems solved by technology

[0003] Due to the instability of the gas compression state and the influence of the gas on the gas state due to the work done by the gas on the weight, the pressure of the gas after each compression changes greatly, which in turn causes a large difference in the excitation energy each time, and the excitation consistency is poor.
