Problems solved by technology
Existing hydraulic compressors generally use explosion-proof electromagnetic reversing valves to meet explosion-proof requirements. At the same time, forced buffering at the stroke end is used to reduce the impact of the pressurized cylinder to achieve the purpose of reducing vibration and noise. However, the explosion-proof cost is high and cannot be completely eliminated. The risk of electric spark detonation, and the effect of vibration and noise reduction is not ideal

The invention discloses a liquid-controlled self-reversing gas pressurized cylinder, which is used in a gas compressor. The buffer sleeve at the end of the stroke divides the low-pressure hydraulic chamber into two parts: one part passes through the throttle port of the adjustable needle valve to The oil is discharged outside, and the hydraulic oil is supplied to the control valve chamber of the hydraulic control reversing valve through the internal flow channel to complete the automatic reversing action of the gas booster cylinder, and the size of the throttle port of the needle valve can be adjusted to adjust the inertia of the booster cylinder The buffering effect of the load; the other part is used to connect the high-pressure hydraulic chamber and the low-pressure hydraulic chamber of the booster cylinder at the end of the booster stroke to realize the self-relieving of the hydraulic system at the end of the stroke of the booster cylinder. The invention can simultaneously realize self-reversing at the stroke end of the booster cylinder and effective buffering of the inertial load of the booster cylinder, has obvious effects of reducing hydraulic reversing impact and reducing inertial load impact, and can effectively improve the service life of the gas booster cylinder , reduce the overall operating vibration and noise of the hydraulic compressor, and have high engineering practical application value.
Description
technical field [0001] The invention relates to the field of petroleum equipment. More specifically, the present invention relates to a hydraulically controlled self-switching gas pressurized cylinder. Background technique [0002] Gas pressurization is widely used in the field of gas transportation, and the compressor is the key equipment for gas booster transportation. Hydraulic compressors have been widely used in natural gas refueling sub-stations because of their wide pressure range and relatively low cost. The gas booster cylinder is the core equipment of the hydraulic compressor. [0003] As people's awareness of safety and environmental protection gradually increases, hydraulic compressors must first meet the explosion-proof characteristics. At the same time, the vibration and noise of hydraulic compressors have gradually become important indicators to measure the overall performance of compressors. Existing hydraulic compressors generally use explosion-proof elec...
