Embodiment Construction

[0012] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation manner.

[0013] As shown in the accompanying drawing, a device for forced flameout of an engine includes an oil and gas control block 2, and the oil and gas control block is provided with an oil inlet oil passage 1, an oil outlet oil passage 8 and a control oil passage 9, forming a structure similar to a three-way valve. The control oil passage 9 cooperates with the high-pressure gas control valve 6 to realize the connection and cut-off of the oil inlet passage 1 and the oil outlet passage 8, the oil and gas control block 2 and the oil outlet block 3 are fixedly connected by fastening bolts, and the oil outlet The block 3 and the oil outlet joint 4 are fixedly connected by fastening bolts, and the oil outlet block 3 and the oil outlet joint 4 have oil passages inside and communicate with the oil outlet oil passage 8 of the oil and...

Abstract

Disclosed is an engine forced flameout device. The technical scheme includes that the engine forced flameout device comprises an oil and gas control block provided with an oil inlet passage, an oil outlet passage and a control oil passage. The control oil passage and a high-pressure gas control valve are matched to connect and disconnect the oil inlet passage and the oil outlet passage, the oil and gas control block is fixedly connected with an oil outlet block which is connected with an oil outlet joint fixedly, both the oil outlet block and the oil outlet joint are provided with oil passages inside, and the oil passages are communicated with the oil outlet passage of the oil and gas control block. The engine forced flameout device is similar to a three-way valve and forcedly flame out and stop an engine by cutting off oil ways of a high-pressure oil pump through the high-pressure gas control valve, and the problem about galloping of a diesel engine is thoroughly solved. Besides, the engine forced flameout device is simple to operate and high in safety.

Description

technical field [0001] The invention relates to an engine forced flameout device. Background technique [0002] When the diesel engine exceeds the rated speed and the speed is out of control, the so-called "speeding" failure phenomenon will occur. The occurrence of the speeding phenomenon will cause the engine to vibrate violently, which will not only seriously damage the parts of the diesel engine, but also endanger people's personal safety. Solve the problem of speeding has attracted more and more attention. [0003] At present, in the field of diesel engines, when "speeding" occurs, the main methods to take are to place the pedal in the non-fuel supply position or block the intake and exhaust pipes, and to step on the brake pedal to allow the engine to be forced to stop. The operation process of these methods is complex and there are many uncertain factors, and the low safety factor cannot truly solve the "running" problem of diesel engines.
