Description

TECHNICAL FIELD

[0001] The utility model belongs to vehicle tail gas treatment field, concretely, the utility model relates to a kind of anti-freezing solution solenoid valve mounting bracket structure. BACKGROUND

[0002] Heavy truck is the key object of environmental regulation because of high load operation, and exhaust emission is significantly higher than passenger car. The existing technology decomposes urea solution into ammonia (NH3) by selective catalytic reduction system (SCR), and reacts with NOx in exhaust gas to generate nitrogen and water. However, high-frequency vibration during heavy truck driving easily causes the connection between bracket and solenoid valve to loosen, affecting the sealing of solenoid valve. Anti-freezing solution pipeline and solenoid valve interface are prone to leakage due to deformation in low temperature environment. The existing bracket lacks stable support for the interface. Solenoid valve maintenance requires disassembling the entire bracket, which is time-consuming and increases maintenance cost. It cannot be compatible with the installation requirements of different types of solenoid valves.

The anti-freezing solution filter is arranged on the urea sensor and connected with the anti-freezing solution inlet to filter impurities in the anti-freezing solution. However, the mounting bracket of the anti-freezing solution solenoid valve cannot solve the problem that the connection between the bracket and the solenoid valve is prone to loosen during high-frequency vibration of heavy truck driving, affecting the sealing of the solenoid valve, and the anti-freezing solution pipeline and the solenoid valve interface are prone to leakage due to deformation in low temperature environment.
