Abstract

The invention relates to the technical field of engines and discloses a valve system capable of changing the flow direction of gas. The valve system comprises a shell and four valves, wherein the shell is a hollow shell; the four valves are sequentially arranged in the shell to partition the shell into five cavities; and four connection pipes are arranged on the shell and are communicated with an inner cavity in the shell respectively. Compared with the prior art, in two states of not extracting negative pressure and extracting negative pressure, the valve system is capable of changing the flow direction of gas.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a valve system. Background technique [0002] When testing the engine bench, valves are usually provided to assist the test, and the valves mainly include ordinary mechanical valves and controllable solenoid valves. In the prior art, when the engine bench test is performed, the engine operation cannot be converted, which restricts the test flexibility and increases the test time. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a valve system for changing the direction of gas flow, and solve the above technical problems. [0004] In order to solve the above problems, the technical solution adopted in the present invention is: [0005] A valve system for changing the direction of gas flow, including a housing and a valve, characterized in that the housing is a hollow housing, and there are four valves,...
