Abstract
The invention discloses a throttle valve gasket comprising a gasket body. The gasket body is an enclosed ring, the enclosed ring is formed by connecting two ends of a great semicircle segment and an irregular arc segment through tangent straight flanges, a connecting boss is further arranged on the outer side of the great semicircle segment, multiple pairs of bosses are arranged on the inner and outer side walls of the gasket body, each boss is integrally semi-cylindrical, and two ends of each boss are in transition connection with the side walls of the gasket body through hemispheres. The throttle valve gasket fits with a throttle valve in shape and is good in assembly effect and small in clearance, so that sealing effect is improved.
Description
Technical field
The present invention relates to the packing ring that auto parts and components use, particularly a kind of throttle valve body packing ring.
Background technique
Produce in more and more flourishing process at modern industry, automobile has become people's requisite traffic tool of living, and output increases day by day.Along with the attention to the person and traffic safety problem, people also more and more pay attention to car mass.Hydraulic control automatic transmission in vehicle structure is to adopt throttler valve to reflect the size of throttle opening, the function of throttler valve is to produce the control oil pressure being directly proportional to throttle opening, pass to main pressure regulator valve and shift valve, control main oil pressure and gear shift, be generally divided into two types: mechanical type throttler valve and vacuum type throttler valve.The seal request of throttler valve is very high, and existing washer sealing effect is bad, easily reveal, or because wearing and tearing and cause leakage after use a period of time.
Summary of the invention
The technical issues that need to address of the present invention are that existing throttler valve washer sealing effect is bad.
For solving the problems of the technologies described above, the invention provides a kind of throttle valve body packing ring, comprise packing ring body, described packing ring body is the annular of sealing, described annular is by one section of big semicircle segmental arc and one section of closed ring that irregular roundness segmental arc two ends are formed by connecting by tangent straight flange respectively, also be provided with a connection boss in the outside of described big semicircle segmental arc, on the interior outer side wall of described packing ring body, be provided with multipair boss, each described boss entirety is semicircle cylindricality, and two ends are excessively connected by the sidewall of the spherical and described seal ring body of semicircle.Throttle valve body packing ring of the present invention, according to the shape of throttle valve body, packing ring is arranged to and suitable streamlined of the shape of throttle valve body, sealing effect is better, connect boss for being connected with throttle valve body, prevent packing ring sliding transfer, the boss that arranges on this inside and outside sidewall of packing ring improves wear resistance, prevents that packing ring from producing fit up gap because of abrasion deformation.
As the preferred technical solution of the present invention, described multipair boss is eight pairs, and wherein six pairs are evenly distributed in described big semicircle segmental arc, a pair of being positioned in described irregular roundness segmental arc, a pair of being positioned at described in one of them on tangent straight flange.
Throttle valve body packing ring of the present invention, the shape of shape and throttle valve body is suitable, assembles effective, gap is little, thereby has improved sealing effect, and the design of boss is not only anti-skidding but also wear-resisting, whole packing ring is improved working life greatly, cost-saved, and need not frequently change.

Fig. 2 is that A-A of the present invention is to sectional view;
Wherein, 1-packing ring body, 2-big semicircle segmental arc, 3-irregular roundness segmental arc, the tangent straight flange of 4-, 5-connects boss, 6-boss.
Embodiment
Describe the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.
As shown in the figure, throttle valve body packing ring of the present invention, comprise packing ring body 1, the annular that described packing ring body 1 is sealing, described annular is by one section of big semicircle segmental arc 2 and one section of closed ring that irregular roundness segmental arc 3 two ends are formed by connecting by tangent straight flange 4 respectively, also be provided with a connection boss 5 in the outside of described big semicircle segmental arc 2, on the interior outer side wall of described packing ring body 1, be provided with multipair boss 6, each described boss 6 entirety are semicircle cylindricality, and two ends are excessively connected by the sidewall of the spherical and described seal ring body 1 of semicircle, described multipair boss 6 is eight pairs, wherein six pairs are evenly distributed in described big semicircle segmental arc 2, a pair of being positioned in described irregular roundness segmental arc 3, a pair of being positioned at described in one of them on tangent straight flange 4.
Throttle valve body packing ring of the present invention, according to the shape of throttle valve body, packing ring is arranged to and suitable streamlined of the shape of throttle valve body, sealing effect is better, connect boss for being connected with throttle valve body, prevent packing ring sliding transfer, the boss that arranges on this inside and outside sidewall of packing ring improves wear resistance, prevents that packing ring from producing fit up gap because of abrasion deformation.
Throttle valve body packing ring of the present invention, raw material adopts fluorine rubber, the characteristic that fluorine rubber has is high temperature resistant, oil resistant and the medicine of resistance to number of chemical corrode, the indispensable materials of cutting-edge science technology such as modern Aviation, guided missile, rocket, space travel, in recent years, along with the continuous lifting that automotive industry requires reliability, Security etc., the consumption of fluorine rubber in automobile also increases rapidly.
Throttle valve body packing ring of the present invention, the shape of shape and throttle valve body is suitable, assembles effective, gap is little, thereby has improved sealing effect, and the design of boss is not only anti-skidding but also wear-resisting, whole packing ring is improved working life greatly, cost-saved, and need not frequently change.
