Abstract

The invention discloses a sealing method for a pulse flow control electromagnetic valve, which includes the steps of cleaning, vacuumizing, resin distributing, sealing, solidification and the like. After test, the electromagnetic valve sealed by the method is free of leakage after working for 20h under the air pressure of 30kg / cm2, sealing effects meet the use requirements of a diesel engine, and the electromagnetic valve can be used for mass production.

Description

technical field [0001] The invention relates to a sealing method of a pulse flow control solenoid valve. Background technique [0002] The pulse flow control solenoid valve is the main component of the diesel engine and has a large application market. The pulse flow control solenoid valve has high sealing requirements, the specific requirement is 28kg / cm 2 It does not leak for 20 hours under air pressure, so the sealing method of the pulse flow control solenoid valve is the key process method for the manufacture of this type of solenoid valve. [0003] The known sealing method is to carry out resin pot injection on the solenoid valve to solve the problem of the airtightness of the solenoid valve. However, due to the high working temperature of the pulse flow control solenoid valve, conventional resins are easy to decompose at high temperatures and affect the sealing performance. Therefore, there is no literature report on the sealing method of the pulse flow control soleno...
