Description
Technical field
The present invention relates to a kind of Intaker controller of diesel engine, be specifically related to a kind of air inlet break.
Background technique
At present, what on diesel engine, generally adopt is that the high pressure oil pump fuel feeding starts, operation, relies on the shutdown handle on the external force pulling high pressure oil pump to carry out oil-break, parking, and this mode is simple to operate easy to use.If hypervelocity, driving phenomenon just appear in a period of time or fuel feed pump plunger corrosion, stuck easily but diesel engine has been stopped using during startup.Relying on the shutdown handle on the external force pulling high pressure oil pump to stop and can't realize in this case, can only be to adopt the method for breaking off in-line, stopping up suction port or relief opening that diesel engine is stopped.Though diesel engine also can be because of oil-break stops after breaking off in-line, the time, long harm was bigger; And adopt the exhaust brake that stops up relief opening, also higher because delivery temperature is higher to the material requirements of using, so cost is high, cost is big, is difficult for being accepted by the user.
Summary of the invention
The purpose of this invention is to provide a kind ofly when hypervelocity, driving phenomenon appear in diesel engine, can stop up the air inlet break that the diesel engine intake mouth stops diesel engine fast.
The present invention adopts following technological scheme: a kind of air inlet break; Comprise casing; Have on the casing and be respectively applied for air outlet that is communicated with the suction tude of diesel engine and the suction port that is communicated with the outlet pipe of air-strainer; Be provided with in the casing and be used to open and close the valve mechanism of suction port and the control mechanism of control valve mechanism work; Said valve mechanism comprises that the door-hinge through the top, air outlet rotates the door-plate with open position and sealing position that is assemblied in the casing; Door-plate be positioned at the closed section that the door-hinge two side portions is respectively the pushing tow section and closes with air outlet envelope establishing in when position sealing, said control mechanism comprises and is slidedly assemblied in the drive unit that the interior slide block that when open position, cooperates with the pushing tow section block of door-plate of casing and driving sliding block move.
Said drive unit comprises the pull bar that an end fixedly is inserted on the slide block, the other end stretches out casing; The axis of pull bar is consistent with the movement direction of slide block; The end that pull bar stretches out casing is fixed with knob handle, is provided with between said slide block and the casing when slide block departs from door-plate and moves slide block is applied the elastic component towards the door-plate active force.
Said air outlet and suction port lay respectively on the forward and backward end wall of casing, and the axis of said door-hinge extends along left and right directions, and said slide block is slidedly assemblied in the casing along fore-and-aft direction.
Said slide block is slidedly assemblied in the casing through the slide bar that extends along fore-and-aft direction, and said elastic component is the stage clip that is sleeved on the slide bar, the rear end inwall apical grafting of an end of stage clip and rear end apical grafting, the other end and the casing of slide block.
Said air outlet is communicated with the suction tude of diesel engine through sleeve pipe; One end of said sleeve pipe is fixed on the front bulkhead outer wall of casing and is communicated with the air outlet; The inwall of end cap coincide sheathed the cooperation with the suction tude outer wall of diesel engine; And offer annular groove on the internal surface of sleeve pipe, be filled with the O RunddichtringO in the annular groove.
Said suction port is communicated with the outlet pipe of air-strainer through the end cap of tubular structure; One end of said end cap is fixed on the aft bulkhead outer wall of casing and is communicated with suction port; The inwall of end cap coincide sheathed the cooperation with the exhaust tube wall of air-strainer; And the ear end face of end cap has the annular retaining edge that extends internally, and is top-loaded with y-type seal ring between annular retaining edge and the casing.
Said air outlet inner edge stretches in the casing.
The closed section of said door-plate closes through ring-shaped rubber plate and the envelope establishing of said air outlet, and said ring-shaped rubber plate is fixed on the closed section of door-plate.
Adopt the air inlet break of said structure; Offer air outlet that is communicated with the suction tude of diesel engine and the suction port that is communicated with the outlet pipe of air-strainer on the casing respectively; Air-strainer is communicated with diesel engine through casing like this; The door-plate of valve mechanism rotates through door-hinge and is assemblied in the casing, and door-plate be positioned at the closed section that the door-hinge two side portions is respectively the pushing tow section and closes with air outlet envelope establishing, make door-plate and door-hinge can form leverage like this; The closed section of door-plate can rotate towards the air outlet under the self gravitation effect, thus the sealing air outlet; The slide block of control mechanism is slidedly assemblied in the casing; When door-plate is in open position; Slide block cooperates the closed section sealing air outlet that can prevent door-plate with the pushing tow section block of door-plate, only under the drive of drive unit, make slide block depart from door-plate and move the closed section that can realize door-plate and move towards the air outlet, simultaneously when door-plate is in sealing; Under the drive of drive unit, door-plate is moved towards door-plate, and the pushing tow section of pushing tow door-plate make door-plate get back to open position.Therefore, when hypervelocity, driving phenomenon appear in diesel engine, make slide block depart from door-plate through accessory drive and move the quick sealing that both can realize the air outlet; Thereby close the diesel engine intake mouth, make slide block move the unlatching that can realize the air outlet, thereby guarantee the diesel engine proper functioning towards door-plate through accessory drive; In air inlet break working procedure; To diesel engine and not influence of equipment thereof, simple in structure, low cost of manufacture, easy to install of while, reliability is high.
In addition, said drive unit comprises the pull bar that an end and slide block are connected, the other end stretches out casing, when hypervelocity, driving phenomenon appear in diesel engine; Get final product through moving behind the pull bar pulling slide block; Behind the releasing lever, slide block can move towards door-plate under the effect of elastic component, and is easy to operate simultaneously.
