Abstract
The utility model discloses a kind of diesel engine fuel shut-off solenoid, comprise housing, coil block and iron core, the left end of coil block is provided with protecgulum, right-hand member is provided with bonnet, coil block, protecgulum and after be covered on housing endoporus carry out riveting by the turned welt at shell inner hole two ends and fix, coil carrier on the winding pull-in winding of coil block, the endoporus of coil carrier is fixed with non magnetic conduit, the endoporus of non magnetic conduit is located in described iron core activity, described iron core is provided with endoporus and is led by guide rod, guide rod is fixedly connected with bonnet, Returnning spring is provided with between iron core and bonnet, the endoporus stretching in protecgulum outside the left end of described iron core is fixedly connected with rod head, it is characterized in that: the just right end face of described iron core and bonnet has inner conical surface design, the just right end face of described bonnet and iron core has male cone (strobilus masculinus) design, inner conical surface is identical with the tapering of male cone (strobilus masculinus).During utility model works, electromagnetism the suction-combining force is stronger, effectively improves and stops oily reaction velocity, facilitate adjustment during installation simultaneously.
Description
Technical field
The utility model relates to a kind of improvement invention of diesel engine fuel shut-off solenoid.
Background technique
Diesel engine fuel shut-off solenoid is for controlling the throttle of diesel engine, and its working principle is: when diesel engine starts, coil electricity makes iron core action, and throttle is opened, and when diesel engine switch-off, iron core return after coil blackout, throttle is closed.The diesel engine fuel shut-off solenoid of prior art, electromagnetism the suction-combining force during work is not very strong, and this compensates with regard to needing the diameter dimension by increasing iron core, and cause fuel shut-off solenoid profile large, adjustment when simultaneously installing is not very convenient.
Summary of the invention
For the deficiencies in the prior art, it is stronger that the purpose of this utility model is to provide electromagnetism the suction-combining force when one works, and effectively improves and stop oily reaction velocity, the diesel engine fuel shut-off solenoid regulated when simultaneously facilitating installation.
The utility model takes following technological scheme:
A kind of diesel engine fuel shut-off solenoid, comprise housing, coil block and iron core, the left end of coil block is provided with protecgulum, right-hand member is provided with bonnet, coil block, protecgulum and after be covered on housing endoporus carry out riveting by the turned welt at shell inner hole two ends and fix, coil carrier on the winding pull-in winding of coil block, the endoporus of coil carrier is fixed with non magnetic conduit, the endoporus of non magnetic conduit is located in described iron core activity, described iron core is provided with endoporus and is led by guide rod, guide rod is fixedly connected with bonnet, Returnning spring is provided with between iron core and bonnet, the endoporus stretching in protecgulum outside the left end of described iron core is fixedly connected with rod head, it is characterized in that: the just right end face of described iron core and bonnet has inner conical surface design, the just right end face of described bonnet and iron core has male cone (strobilus masculinus) design, inner conical surface is identical with the tapering of male cone (strobilus masculinus).
The left end of described protecgulum is fixedly connected with sleeve, the left end of sleeve is threaded with adjustment nut caps, adjusting nut is covered with endoporus step, and under the effect of Returnning spring, described rod head leans and carry out axial limiting by endoporus step on the endoporus step of adjustment nut caps.
Adopt the diesel engine fuel shut-off solenoid of technique scheme, first, the end face that iron core is relative with bonnet is the conical surface, magnetic strength area when pull-in winding is energized between iron core and bonnet electromagnetism the suction-combining force that is larger, iron core is stronger, thus effectively improve fuel shut-off solenoid stop oily reaction velocity, meanwhile, the diameter dimension of iron core does not need to change yet, and makes fuel shut-off solenoid compact structure; In addition, the position of endoporus step can be made to change by rotating adjustment nut caps, so the position of rod head is also just along with change, thus facilitating adjustment when diesel engine fuel shut-off solenoid is installed.
