Description
Technical field
The utility model relates to a kind of air inlet Decompression valves on automobile turbocharger.
Background technique
Traditional air inlet Decompression valves on automobile turbocharger is mechanical valve, there is shortcomings in it, applying unit and customer complaint are very large, and 2,000,000 life tests cannot be passed through, main cause is that elastomer breaks, and causes Decompression valves to lose due function.
For preventing Decompression valves from losing function, market there is again new Decompression valves, sealing with hardware Sealing and PPS plug, because be all very stiff and demanding sealing means, cause seal leakage excessive, increase energy consumption and noise is large.Such as publication number is the electric-controlled decompression valve of turbo supercharger that the Chinese utility model patent of CN202140164U discloses a kind of electromagnetic type, its basic principle arranges a dynamic iron core and a static iron core, outside static iron core, there is coil, during coil electricity, under the effect of electromagnetic force, dynamic iron core band dynamic seal ring is up thus do not seal, and during coil no electric circuit, seal ring plays sealing effect under the force of a spring.The shortcoming that the air inlet Decompression valves on automobile turbocharger of existing electromagnetic type also exists is: the linkage structure between seal ring and dynamic iron core is Hard link structure, all more stiff when sealing or unpacking operates, lack buffering, therefore ring structure easily damages, and need working life to improve.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing air inlet Decompression valves on automobile turbocharger, the utility model provides a kind of air inlet Decompression valves on automobile turbocharger of longer service life.
The technical scheme in the invention for solving the technical problem is: a kind of air inlet Decompression valves on automobile turbocharger, comprise plastic packaging housing, have a coil rack in described plastic packaging housing, described coil rack is arranged with coil, described coil is connected with inserted sheet; Be provided with static iron core in described coil rack, the central authorities of described static iron core are provided with vertical guide shaft, and on described guide shaft, flip sleeve is provided with the dynamic iron core be positioned at below described static iron core, are supported with stage clip between described dynamic iron core and static iron core;
Also comprise a movable sheath, described movable sheath is connected with described dynamic iron core, the bottom surface opening of described movable sheath;
The lower end surface of described plastic packaging housing is provided with a fixed cover, seal between the lower end surface of described fixed cover and plastic packaging housing, described movable sheath is positioned at described fixed cover, also comprise a flexible sheet, one end of described flexible sheet is connected with described fixed cover, and the other end of described flexible sheet is connected with described movable sheath.
Further, the longitudinal section of described flexible sheet takes the shape of the letter U.
Further, the lower end surface of described plastic packaging housing also has a circle seal groove, described fixed cover is provided with seal ring, in the seal groove described in described seal ring embeds.
Further, the bottom surface of described movable sheath is provided with seal ring.
The utility model also has following additional technical feature:
Described coil rack is also provided with one and is placed on carbon steel cover outside described dynamic iron core.
On described guide shaft, flip sleeve is provided with axle sleeve, and described dynamic iron core is located on described guide shaft by described axle sleeve flip sleeve.
The upper end of described plastic packaging housing is provided with a socket cover, and described inserted sheet is positioned at described socket cover.
Described movable sheath is nested in the lower end of described dynamic iron core.
In use, tracheae is connected on the lower end surface of movable sheath the utility model, when inserted sheet access failure power supply, due to the effect of stage clip, makes dynamic iron core drive movable sheath to move downward, blocks the outflow of gas, play the effect of hermetically closing; Upwards lifted by dynamic iron core because coil produces axial force of magnetic field when inserted sheet switches on power, thus drive movable sheath to move upward, make to have gap between movable sheath and tracheae, no longer seal, gas flows out, and plays the function of unlatching.
The beneficial effects of the utility model are: movable sheath is connected with flexible sheet, and in upstream or downstream process, flexible sheet material itself has enough wear resistancies and sealing, therefore not fragile, longer service life; Capable of reducing energy consumption 60%, and very reliable.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model and uses schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, air inlet Decompression valves on automobile turbocharger, comprise plastic packaging housing 1, there is in described plastic packaging housing 1 coil rack 2, described coil rack 2 is arranged with coil 3, described coil 3 is connected with inserted sheet 4, and the upper end of the housing of plastic packaging described in the present embodiment 1 is provided with a socket cover 5, and described inserted sheet 4 is positioned at described socket cover 5; Be provided with static iron core 6 in described coil rack 2, the central authorities of described static iron core 6 are provided with vertical guide shaft 7, and on described guide shaft 7, flip sleeve is provided with the dynamic iron core 8 be positioned at below described static iron core 6, are supported with stage clip 9 between described dynamic iron core 8 and static iron core 6.On guide shaft 7 described in the present embodiment, flip sleeve is provided with axle sleeve 10, and described dynamic iron core 8 is located on described guide shaft 7 by described axle sleeve 10 flip sleeve.
