Abstract
The utility model discloses a double-V-shaped four-level reciprocating piston type natural gas compressor which comprises two first-level cylinder components (1), a second-level component (2) and a third-fourth-level cylinder component (3). The two first-level cylinder components (1) are arranged on the upper left side of a crankcase (5) and distributed in a 90-degree and V-shaped mode, and the second-level cylinder component (2) and the third-fourth-level cylinder component (3) are arranged on the upper right side of the crankcase (5) and distributed in a 90-degree and V-shaped mode. The natural gas compressor of the structure can progressively compress natural gas in a natural state by four times, effectively reduces exhaust gas temperature of each level of compressed gas and is especially suitable for high temperature environments and low pipe network pressure environments. The width of the crankcase is reduced by optimizing included angles between the axes of the four cylinder components distributed in a double-V-shaped mode. Thus, the natural gas compressor is compact in distribution.

In addition, traditional single V-type air compressor is provided with two cylinder parts on it, and the angle of two cylinder parts is 120 °, and the area that takies during installation is large, and structure is not compact.
Summary of the invention
The purpose of this utility model provides a kind of air cylinder structure of natural gas compressor of compact structure, can with the rock gas under the nature through four step by step compressions, effectively reduce the delivery temperature of every grade of pressurized gas.
For this reason, the air cylinder structure of a kind of double V-shaped level Four reciprocating piston type natural gas compressor that the utility model provides, key is: comprise two first-stage cylinder parts, secondary cylinder parts and three level Four cylinder parts, four link to each other with crankcase by each self-corresponding piston crank mechanism respectively, wherein two first-stage cylinder parts are positioned at the upper left side of crankcase and are 90 ° V-type layout, secondary cylinder parts and three level Four cylinder parts are positioned at the upper right of crankcase and are 90 ° V-type layout, the axis of secondary cylinder parts is parallel with the axis of the first-stage cylinder parts that are positioned at the same side, three level Four cylinder parts are parallel with the axis of the first-stage cylinder parts that are positioned at the same side, be provided with one-level suction valve and one-level outlet valve on the described first-stage cylinder parts, be provided with secondary suction valve and secondary exhaust valve on the secondary cylinder parts, be provided with three grades of suction valves on the three level Four cylinder parts, three grades of outlet valves, level Four suction valve and level Four outlet valve.
Described one-level suction valve and one-level outlet valve are positioned at the left side of first-stage cylinder parts, and secondary suction valve and secondary exhaust valve are positioned at the right side of secondary cylinder parts, three grades of suction valves, three grades of outlet valves, and level Four suction valve and level Four outlet valve are positioned at the right side of three level Four cylinder parts.By optimizing the position of row, suction valve, conveniently install and remove and make the structure of cylinder more compact.
The bottom of the both sides, front and back of described crankcase is outward extended with the installation journal stirrup, has bolt through-hole at the installation journal stirrup.When traditional crankcase is installed, a L shaped mounting bracket need to be set in addition, the facade of L shaped mounting bracket links to each other with crankcase, the horizontal plane of L shaped mounting bracket links to each other with frame, this mounting structure, easily loosening when facade is installed, the rigidity of crankcase is also bad.Crankcase after the improvement carries mounting structure, has reduced intermediate connector and mounting points, has strengthened the rigidity of crankcase, has guaranteed the soundness of installing, and avoids installing rear appearance and becomes flexible.
The beneficial effects of the utility model: the natural gas compressor with this structure can effectively reduce the delivery temperature of every grade of pressurized gas with the rock gas under the nature through four step by step compressions, is particularly suitable for hot environment, the environment of low ductwork pressure; And by optimizing four axis angles that are the cylinder part of double V-shaped layout, reduce the width of crankcase, thereby it is more compact that air compressor is arranged.
