Beneficial effect：

1. in the market like product can only test relay valve conduction status, and conduction detection is empty by handle ball valve and compression Gas is whether there is by realizing；The test equipment for ERV electronic relay valves that the utility model is provided is then by controlling mould Block provides signal control solenoid valve conduction pipeline gas circuit.

2. in the market like product can only detect whether ERV electronic relays valve turns on, it is impossible to when detection conducting is spent Between, and turn on the key core index that the spent time is then ERV electronic relay valves；Conducting the spent time is shorter, says The bright reaction of electronic relay valve and action are sensitiveer, and the braking distance of vehicle is shorter, drives a vehicle safer；The utility model is provided The test equipment for ERV electronic relay valves, the real-time conduction time of ERV electronic relay valves can be detected.

3. in the market same category of device is to pipeline pressure without detection, and what the utility model was provided is used for ERV electronic relay valves Test equipment, can be by installing pressure sensor, the curved line relation that detection pressure is changed over time in real time, and will detect data Control module is delivered to, the standard requirement of control presupposition analysis unit is compared in real time, and whether qualified very clear, operation is more Plus simple, testing result more science and visualization.

4. the utility model provide the test equipment for ERV electronic relay valves, can detect extensively different manufacturers or The ERV electronic relay distributing valves of brand, are both special equipment, are the common apparatus of electronics ERV relay distributions valve detection again.

Brief description of the drawings

, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art The accompanying drawing used required in description is briefly described.

Fig. 1 is logic diagram of the present utility model.
