Abstract
The utility model discloses a kind of turbosupercharger exhaust gas by-pass valve final controlling element, this structure is coordinated and realizes fool-proof design with positioning block by the locating slot being arranged on upper and lower cover, guarantee that upper and lower covers accurately fastens, thereby the problems such as reduction gas leakage and electrical connector angle are bad, not only assembling is simple, and reliable in structure.
Description
Technical field
The utility model relates to a kind of turbosupercharger exhaust gas by-pass valve final controlling element, particularly final controlling element final controlling element positioning means for a kind of turbosupercharger exhaust gas by-pass valve.
Background technique
Common final controlling element adopts common pneumatic mode work, is also pneumatic actuator, thus its utilize draught head act on inner diaphragm go to drive valve reach open and close or any opening degree.And pneumatic actuator on turbosupercharger exhaust gas by-pass valve is the important spare part on exhaust gas by-pass valve, thereby its Main Function is to coordinate the actual conditions of motor to go the amount that regulates cycle gas to enter motor to optimize motor real work efficiency. exhaust gas by-pass valve enters final controlling element internal pressure by adjustings or adopts vacuum system to regulate atm difference inside and outside control final controlling element to control the motion of final controlling element interior diaphragm, thereby regulate the aperture of wastegate, reach the object that regulates suction pressure value.
The lid of this final controlling element is mainly made up of two-part, comprises upper cover and lower cover.Both major functions are after combination, to form one, for the matrix of whole final controlling element, can mutually assemble with bypass valve, the diaphragm of compacting simultaneously forms seal space, original design but combination after be difficult for being in place, cause gas leakage or electrical connector and bypass valve relative angle inconsistent.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the turbosupercharger exhaust gas by-pass valve that a kind of lid is easily in place and installation precision is high final controlling element.
The utility model solves the technological scheme that its technical problem adopts:
Turbosupercharger exhaust gas by-pass valve final controlling element, the lower cover that comprises upper cover and fasten with upper cover, is characterized in that: described upper cover or under cover and be provided with positioning block, described lower cover or on cover and be provided with the locating slot coordinating with this positioning block.
On described upper cover outer wall, be relatively provided with L shaped tabs, described locating slot is made up of the gap between two tabs.
Described positioning block is rectangular block.
It is two that described positioning block is symmetrical arranged.
The beneficial effects of the utility model are: this structure is coordinated and realizes fool-proof design with positioning block by the locating slot being arranged on upper and lower cover, guarantee that upper and lower cover accurately fastens, thereby the problems such as reduction gas leakage and electrical connector angle are bad, not only assembling is simple, and reliable in structure.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the three-dimensional view of the utility model upper cover;
Fig. 2 is the three-dimensional view of the utility model lower cover.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model discloses a kind of turbosupercharger exhaust gas by-pass valve final controlling element, the lower cover 2 that comprises upper cover 1 and fasten with upper cover 1, upper cover 1 outer wall periphery is evenly equipped with elastic fastening plate 3, cramp 3 internal surfaces are provided with the fixture block 4 with inclined-plane, lower cover 2 outer wall peripheries are provided with the edge 5 concordant with lower cover 2 opening surfaces, and 5 lower ends, edge are provided with block 6, and described fixture block 4 blocks mutually with block 6.
As shown in the figure, lower cover 2 is provided with positioning block 7, it is two that positioning block 7 is symmetrical arranged, described positioning block 7 is rectangular block, certainly the concrete shape of positioning block 7 does not form the restriction to this patent, and the cross section of positioning block 7 also can be trigonometric form or regular hexagon etc., and upper cover 1 is provided with the locating slot 8 coordinating with this positioning block 7, when rectangular block and locating slot 8 are chimeric time, upper cover 1 accurately fastens with lower cover 2.The concrete structure of locating slot 8 is as described below: on upper cover 1 outer wall, be relatively provided with L shaped tabs 9, described locating slot 8 is made up of the gap of 9 of two tabs, tabs 9 is L shaped, thereby tabs 9 has certain distance with upper cover 1 outer wall, in the time of lower cover 2 that upper cover 1 fastens, because thering is certain space between tabs 9 and upper cover 1 outer wall, can avoid lower cover 2 edges 5 to move and cause obstacle.
Certainly, the above-mentioned just description of instantiation, this structure can also adopt at upper cover 1 outer wall positioning block 7 is set, and the mode of establishing locating slot 8 on lower cover 2.
A kind of turbosupercharger exhaust gas by-pass valve final controlling element above the utility model embodiment being provided, be described in detail, applied specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation is just for helping to understand method of the present utility model and core concept thereof; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
