Description
Technical field
The utility model relates to a kind of air inlet Decompression valves of 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.
The recent air inlet Decompression valves having occurred the automobile turbocharger improved, if the patent No. is the technological scheme disclosed in the Chinese utility model patent of 201520300661.6, it comprises plastic packaging housing, there is in plastic packaging housing a coil rack, coil rack is arranged with coil, and coil is connected with inserted sheet; Be provided with static iron core in coil rack, the central authorities of static iron core are provided with vertical guide shaft, and on guide shaft, flip sleeve is provided with the dynamic iron core be positioned at below static iron core, move and are supported with stage clip between iron core and static iron core; Dynamic iron core overcoat has metal magnetosheath, and metal magnetosheath remains in plastic packaging housing; Also comprise one and be positioned at movable sheath below plastic packaging housing, movable sheath is connected with dynamic iron core, and the bottom surface of movable sheath offers pore; The lower end surface of plastic packaging housing is provided with a fixed cover, and seal between the lower end surface of fixed cover and plastic packaging housing, movable sheath is positioned at fixed cover, and one end of a teflin ring is connected with fixed cover, and the other end of teflin ring is connected with movable sheath.In use, tracheae is connected on the lower end surface of movable sheath, 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.
But the shortcoming that the air inlet Decompression valves of this follow-on automobile turbocharger also exists is: the sealing between movable sheath and fixed cover is the sealing between plastics and plastics, it is not firm to seal, and easily produces gas leak phenomenon from the edge of teflin ring.
