Abstract
The utility model discloses a diesel engine emergency parking system with a safety protection function. The diesel engine emergency parking system comprises a control device, an emergency parking electromagnetic valve and parking cylinders, and is characterized in that the control end of the emergency parking electromagnetic valve is connected with the emergency parking control end of the control device; external compressed air enters into the parking cylinders after passing through the emergency parking electromagnetic valve; the emergency parking electromagnetic valve comprises two parallel two-position three-way electromagnetic valves; both the control ends of the two two-position three-way electromagnetic valves are connected with the emergency parking control end of the control device; and the parking cylinders are distributed in parallel. Due to the arrangement of the two parallel two-position three-way electromagnetic valves, the parking action and the safety of a diesel engine can be guaranteed.
Description
Technical field
The utility model relates to the shutoff control unit of diesel engine, more particularly, relates to a kind of diesel engine emergency stopping system with function of safety protection.
Background technique
Existing diesel engine generally is furnished with emergency stopping system, is used to control diesel engine and stops in emergency, and the diesel engine emergency stopping system comprises control gear, solenoid valve and parking cylinder stop in emergency; The control end of solenoid valve of stopping in emergency links to each other with the emergency shut-down control device end of control gear; The solenoid valve that stops in emergency is a two position three-way valve, and the external compression air is connected to the suction port of the solenoid valve that stops in emergency, when diesel engine speed surpasses the setting rotating speed; The telecontrol case of control gear sends electrical signal and gives the solenoid valve that stops in emergency; The solenoid valve that stops in emergency is opened, and the external compression air gets into the parking cylinder through the solenoid valve that stops in emergency, and ejects the fore-set in the cylinder; Get to zero fuel feeding position to the Injection Pump of diesel engine oil tooth, diesel engine is stopped in emergency; When running into urgency and need manual work to stop in emergency, press the emergency stop push button on the control panel of control gear, the control solenoid valve that stops in emergency is opened, and also can reach the purpose of stopping in emergency.But because the solenoid valve that stops in emergency is operated under the environment of steam mist of oil, the solenoid valve that possibly cause stopping in emergency is insensitive or do not work, and influences the safety of diesel engine.
The model utility content
The purpose of the utility model is to provide a kind of diesel engine emergency stopping system with function of safety protection, realizes protection diesel engine emergency.
The purpose of the utility model realizes through following technological scheme: a kind of diesel engine emergency stopping system with function of safety protection; Comprise control gear, solenoid valve and parking cylinder stop in emergency; The control end of solenoid valve of stopping in emergency links to each other with the emergency shut-down control device end of control gear; The external compression air gets into the parking cylinder behind the solenoid valve that stops in emergency; It is characterized in that: the said solenoid valve that stops in emergency is made up of the two-position three way magnetic valve that two parallel connections are provided with, and the control end of two two-position three way magnetic valves all links to each other with the emergency shut-down control device end of control gear.The described parking cylinder of the utility model is a plurality of, is parallelly connected shape and distributes.
Compared with prior art, the utility model technology has the following advantages:
Two two-position three way magnetic valves of the parallel connection setting of the utility model can be guaranteed the parking action of diesel engine, guarantee the safety of diesel engine.
Description of drawings
Fig. 1 is the connection schematic representation of the utility model diesel engine emergency stopping system.
Among the figure: 1. control gear; 11. control panel; 111. emergency stop push button; 2. solenoid valve stops in emergency; 21. two-position three way magnetic valve; 3. parking cylinder.
Embodiment
Below in conjunction with specific embodiment the utility model is further set forth.
A kind of diesel engine emergency stopping system as shown in Figure 1 with function of safety protection, it comprises control gear 1, the solenoid valve 2 parking cylinders 3 that stop in emergency, the control end of the solenoid valve 2 that stops in emergency links to each other with the emergency shut-down control device end of control gear 1; In the present embodiment; Control gear 1 has control panel 11; Control panel 11 is provided with the emergency stop push button 111 of manual control or telecontrol; This emergency stop push button 111 can be used as and is the emergency shut-down control device end, and the control end of the telecontrol case of control gear links to each other with emergency stop push button 111, is used for remote auto control and stops in emergency.
The external compression air gets into parking cylinder 3 behind the solenoid valve 2 that stops in emergency, wherein, the solenoid valve 2 that stops in emergency receives emergency stop push button 111 controls, is used to control diesel engine and stops in emergency; Parking cylinder 3 is a plurality of, is parallelly connected shape and distributes.
The solenoid valve 2 that stops in emergency is made up of the two-position three way magnetic valve 21 that two parallel connections are provided with; Two two-position three way magnetic valves 21 constitute or the door form; Promptly; The suction port of two two-position three way magnetic valves 21 all inserts same external compression air, and the air outlet of two two-position three way magnetic valves 21 all is connected to the suction port of parking cylinder 3, and the control end of two two-position three way magnetic valves 21 all links to each other with the emergency shut-down control device end.
When diesel engine ran well, two two-position three way magnetic valves 21 were in closed state, and this moment, the external compression air did not get into the parking cylinder; When needs stop in emergency; Press emergency stop push button 111 or the telecontrol case Remote emergency stop push button through control gear 1 111 is connected; Two two-position three way magnetic valves 21 all commutate and become on-state under the normal condition, and the external compression air can get into parking cylinder 3 through the solenoid valve 2 that stops in emergency, and the fore-set of parking cylinder 3 is ejected; Get to zero fuel feeding position to the Injection Pump of diesel engine oil tooth, make diesel engine stop in emergency (shutting down); But after pressing emergency stop push button 111 or telecontrol case Remote emergency stop push button 111 connections through control gear 1; When one of them of two two-position three way magnetic valves 21 can't be accomplished switching-over work; Another can guarantee that the external compression air gets into parking cylinder 3; Thereby guarantee that diesel engine stops, and realizes function of safety protection.
Certainly; The utility model is not limited to above-mentioned mode of execution; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
