Abstract

The invention belongs to the technical field of air valve testing and particularly relates to equipment suitable for testing the performance of an air valve of a railway vehicle air conditioning unit.The equipment comprises a test support and an operation platform. The test support is installed on one side of an upper portion of the operation platform. The test support is used for installing theair valve. A forward timer, a reverse timer, a forward switch and a reverse switch are mounted on the operating platform; the forward timer is electrically connected with the forward switch to controlthe power-on time of the forward switch; the reverse timer is electrically connected with the reverse switch to control the power-on time of the reverse switch; an air valve actuator on the air valveis electrically connected with a forward and reverse rotation mode, the forward and reverse rotation mode is electrically connected with the forward rotation switch and the reverse rotation switch toachieve the effect of mutually switching power-on modes, and the forward rotation switch and the reverse rotation switch are electrically connected with a power source to supply power. The problem that the air valve of the railway vehicle air conditioning unit is difficult to test is solved.

Description

technical field [0001] The invention belongs to the technical field of air valve testing, in particular to a test device suitable for the air valve performance of an air-conditioning unit of a rail vehicle. Background technique [0002] At present, the air valve test of rail vehicle air-conditioning units needs to be carried out inside the air-conditioning unit, but the defects of this method of testing are as follows: [0003] Occupies space, the test needs to be carried out on the air conditioning unit and the original unit must be in good working condition, otherwise there are many influencing factors; [0004] Inconvenient disassembly and assembly, because the internal layout of the air conditioning unit is compact, it is inconvenient to repeatedly disassemble and install the damper test; [0005] The time is uncontrollable, because the damper is driven by the damper actuator, the control of the damper actuator needs to be set during the test, but most air-conditioning ...
