Abstract

The invention provides a diesel engine fuel cut-off electromagnetic valve with switch indication. The diesel engine fuel cut-off electromagnetic valve comprises a closing piece and a valve body, the closing piece is installed in the valve body, a switch mechanism is fixedly installed above the closing piece, a switch indicating circuit is installed above the switch mechanism, one end of the switch indicating circuit is connected with an electromagnetic valve coil, and the other end of the switch indicating circuit is connected with a valve body shell. An indicator lamp of the switch indicating circuit is located on the outer wall of the valve body shell. According to the diesel engine fuel cut-off electromagnetic valve with switch indication, when the electromagnetic valve is powered on, the closing piece is lifted from the valve seat, a switch of the switch indicating circuit is turned on through the switch mechanism, and the indicator lamp is turned on. When the electromagnetic valve is powered off, the closing piece is seated, the switch of the switch indicating circuit is switched off, the indicator lamp is turned off, and the state of the closing piece can be visually judged.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, and in particular relates to a diesel engine fuel cut-off electromagnetic valve with switch indication. Background technique [0002] With the continuous improvement of diesel engine automatic control technology, the judgment of the working state of the diesel engine and the maintainability of the diesel engine are also required to be higher. The currently used diesel fuel cut-off solenoid valve does not have a working status indication whether it is on or off. Therefore, it is impossible to accurately judge the working state of the diesel engine. When there is a problem with the solenoid valve or the work is not in place, it is not known. This problem needs to be solved urgently. Contents of the invention [0003] In view of this, the present invention aims to propose a diesel engine fuel cut-off solenoid valve with switch indication, and the problem that the switch state of the diesel...
