Abstract
The invention relates to components of a turbocharger for an engine, in particular to a waste gas bypass valve for the turbocharger. The waste gas bypass valve comprises a disk-shaped valve plate cover body. A pin shaft is formed at the rotation center of the valve plate cover body. A rocker arm plate is arranged on the pin shaft in a sleeved mode through a through hole formed in the rocker arm plate. The upper end of the pin shaft is further connected with a gasket. The front end of the gasket is bent towards one side of the valve plate cover body to form a stop plate. A first gap is reserved between the inside plane of the stop plate and the side plane of the rocker arm plate. The bottom plane of the gasket is supported by a boss surface of the pin shaft. A second gap is reserved between the bottom plane of the gasket and the upper plane of the rocker arm plate. A rotating shaft is connected to the end, extending out of the outer side of the valve plate cover body, of the rocker arm plate in a welding mode. By the adoption of the waste gas bypass valve, harmful abrasion caused by relative motion of the valve plate cover body and the rocker arm plate can be effectively reduced, the service life is effectively prolonged, and the reliability of the bypass valve applied to a natural gas engine is improved.

Background technique
Along with the development of natural gas engine technology, and the enhancing of people to environmental protection consciousness, increasing vehicle is brought into use natural gas engine.Because it has obvious superiority and good economic benefit aspect discharge, improving air quality and reducing important in inhibiting aspect vehicle maintenance cost.
The exhaust-gas turbocharger of natural gas applications has very important effect therein, and for motor has, more powerful power provides guarantee for it.And the utilization rate of bypass valve, also than the confidential height of ordinary diesel oil, especially has higher requirement to the motion frequency of bypass valve, the friction etc. of impacting inertia, link relative movement in pressurized machine.Therefore,, in natural gas applications, the project organization of supercharger bypass valve and working life are also in requisition for more strict control and improvement.
In traditional supercharger bypass valve design, bypass valve valve block and rocking arm sheet link together by pin, and form at valve block bottom welding or riveted joint.Due under the effect of air-flow, after welding or riveted joint, valve block body can rotate by axial 360 degree in rocking arm film perforation together with pin, has aggravated the wearing and tearing that produce due to motion between part.After long-play, occur the relative movement wearing and tearing of rocking arm film perforation inwall and pin axle outer wall, gap increases, and causes valve block to fit badly when low engine speed, even comes off, and has a strong impact on the performance of motor.Therefore, the bypass valve of this structure is not especially suitable on the pressurized machine of natural gas engine application, and its reliability and structure all can not meet the distinctive application requirements of rock gas.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of turbosupercharger exhaust gas by-pass valve is provided, adopt this bypass valve can effectively reduce the unfavorable wearing and tearing that bring due to relative movement between valve block lid body and rocking arm sheet, effectively improve working life, improve the reliability of bypass valve in natural gas engine application.
According to technological scheme of the present invention: a kind of turbosupercharger exhaust gas by-pass valve, feature is: comprise discoid valve block lid body, the gyration center of described valve block lid body is formed with pin axle, rocking arm sheet is sheathed on described pin axle by the through hole arranging on it, pin axle upper end is also fixed with pad, on described pad, be formed with at least one blocking arm, blocking arm front end forms catch after described valve block lid body one lateral buckling, between described catch inner side plane and the side plane of rocking arm sheet, leave the first gap, described pad base plane is supported in the boss face of described pin axle, and between plane, be reserved with the second gap on described pad base plane and rocking arm sheet, the end that described rocking arm sheet stretches out valve block lid body outside has been welded to connect rotatingshaft.
As a further improvement on the present invention, described rocking arm sheet comprises supporting portion, the joint that one connects, and described connection part is in valve block lid body outside, and joint end face is provided with curve bath, and joint is towards Yi Cewei inclined-plane, supporting portion.
As a further improvement on the present invention, described valve block body is formed with pin axle one side surface for middle high, conical surface that edge is low.
As a further improvement on the present invention, on described pad, be formed with a blocking arm, and described blocking arm end catch is towards any side plane bending of rocking arm sheet.
As a further improvement on the present invention, on described pad, be formed with two blocking arms, and be in line or rectangular-shaped layout between two blocking arms.
As a further improvement on the present invention, on described pad, be formed with three blocking arms, and between three blocking arms, become " fourth " word shape to arrange.
Technique effect of the present invention is: simple compact, the highly versatile of product structure of the present invention; By restriction bypass valve valve block lid body, because axial 360 degree of airflow function in running freely rotate, reduce the relative movement wearing and tearing between pin axle and rocking arm film perforation; The change of valve block lid body diameter does not have a direct impact its anti-rotating function, and the application of the valve block lid body of different sizes is had to stronger versatility; Effectively anti-rotating function is integrated on pad, the structural strength of pad has also been strengthened.
