High-pressure gas box pump

Abstract

The invention provides a high-pressure gas box pump which comprises a low-pressure gas inlet pipe, a high-pressure exhaust pipe, pressure cylinders and transmission rods connected with pistons in the pressure cylinders, the volumes of containing cavities of the plurality of pressure cylinders are sequentially decreased in the gas flowing direction, one-way flow guide pieces are arranged on gas inlets and / or gas outlets, each one-way flow guide piece is provided with a plurality of valves, the bottoms of the valves are sequentially connected to define a ring, the plurality of valves are in an open state when separated and are in a closed state when gathered, and the one-way flow guide pieces are in a state parallel to the gas flowing direction after being completely opened, so that the one-way flow guide pieces have a very low resistance coefficient after being completely opened, the high-pressure gas box pump has ultrahigh-pressure application prospects, the pressure cylinders with the same stage number are arranged oppositely and are controlled by corresponding push-pull rods on rod sections at the two ends of the transmission rod respectively, and the high-pressure gas box pump can achieve the purpose of multi-stage synchronous and continuous pumping of high-pressure gas.

Description

technical field [0001] The invention relates to the field of high-pressure gas pump mechanical equipment, in particular to a high-pressure gas tank pump. Background technique [0002] A high-pressure air pump is a type of pump used to pressurize gas to output high-pressure gas. The more common high-pressure air pumps include air compressors. In order to achieve the purpose of outputting high pressure, the high-pressure air pump has high requirements for sealing and air flow check. Therefore, the check valve, which is an indispensable part of the high-pressure air pump, is currently used in the high-pressure air pump. Structurally, lifting check valves are often used, such as a new type of high-pressure air pump intake check valve disclosed in Chinese patent application number CN201520244765.X. The high-pressure air pump intake check valve mainly includes a valve body and a valve core. The valve body is provided with a connected air inlet and an air passage, the valve core i...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a high-pressure gas tank pump to solve the following technical problems in the prior art: the spool of the check valve of the existing high-pressure air pump is directly set In the passage, and in the open state, the non-return piece on the valve core is still set in the form of perpendicular to the air passage, which will make the high-pressure gas suffer a lot of resistance in the air passage, the resistance coefficient of the one-way valve If it is too large, it will affect the circulation of high-pressure gas, and also reduce the energy conversion rate of the high-pressure air pump using this check valve
