Abstract
The utility model discloses an internal combustion locomotive engine cylinder cover sealing pad. The section of the sealing pad is arranged to be two portions in upper-lower connection, a lower portion (1) is semicircular or circular and is embedded in a sealing member groove, an upper portion is arranged to be a parallel sealing face (2) in upper-lower connection with a sealed member, and at least two protruding sealing lines (3) are arranged on the sealing face (2). The sealing pad integrates the advantages of an O-shaped ring and a parallel pad, thereby being quite good in sealing effect, and the shape of the whole sealing pad corresponds to that of the sealed member groove, so that mounting deformation is avoided effectively, and the sealing pad is more reliable in sealing performance.
Description
Technical field
The utility model relates to the sealing gasket using on a kind of engine cylinder cowl of railway locomotive accessory, especially internal combustion locomotive.
Background technique
The sealing gasket of existing beeliner engine cylinder cover is the O-ring seals of standard, seal ring be shaped as circle, cross section is also circular, is arranged in the groove that cross section is rectangle and seals.Because O-ring seals is simple in structure, and form standardization, so highly versatile, replacing is installed and is all very easy to.But because the shape of engine cylinder cover is also non-circular, but irregular polygonal, after installing there is distortion in seal ring, can affect sealing effect, meanwhile, because seal ring cross section is also simple circular, potted line is only a point, the leakage of oil of easily wearing and tearing, and sealing effect is bad.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the above problems, and a kind of internal combustion locomotive engine cylinder sealing cushion for cover of good sealing effect is provided.
The cross section of the utility model internal combustion locomotive engine cylinder sealing cushion for cover is made as upper and lower connected two-part, bottom is semicircle or circular in embedding sealing part groove, top be made as with by the sealing surface of the upper and lower flat shape of joining of Sealing, sealing surface is provided with the potted line that is no less than twice projection.
As a kind of improvement, internal combustion locomotive engine cylinder sealing cushion for cover be made as with by the corresponding shape of Sealing groove shape.
Adopt technique scheme, the bottom of internal combustion locomotive engine cylinder sealing cushion for cover is semicircle or circular, in embedding sealing part groove, with by the upper and lower joining part of Sealing, be the flat shape pad with multiple-sealed line, the advantage that so just combines O shape circle and flat shape pad, sealing effect is very good, and the shape of whole sealing gasket is with corresponding by Sealing groove shape, thereby effectively avoided installation deformation, sealability is more reliable.
Accompanying drawing explanation
Fig. 1 is the sectional shape schematic diagram of the utility model sealing gasket.
Fig. 2 is that A shown in Fig. 1 is to local enlarged diagram.
Fig. 3 is the shape schematic diagram of a kind of mode of execution of the utility model sealing gasket.
Embodiment
As shown in Figure 1, the cross section of the utility model internal combustion locomotive engine cylinder sealing cushion for cover is divided into upper and lower connected two-part, bottom 1 is semicircle or circular, in embedding sealing part groove, top is made as the sealing surface 2 of flat shape, sealing surface 2 is contacted by Sealing with upper and lower, as shown in Figure 2, is also provided with the potted line 3 that is no less than twice projection on sealing surface 2.Such sealing gasket combines the advantage of O shape circle and flat shape pad, and is sealed by multiple-sealed line, and sealing effect is very good.In addition, the profile of sealing gasket can make with by the corresponding shape of Sealing groove shape, as shown in Figure 3, be exactly a kind of polygonal, effective like this installation deformation of having avoided sealing gasket, has guaranteed sealing effect.
Claims (2)
1. an internal combustion locomotive engine cylinder sealing cushion for cover, it is characterized in that: the cross section of described sealing gasket is made as upper and lower connected two-part, bottom (1) is semicircle or circular in embedding sealing part groove, top be made as with by the sealing surface of the upper and lower flat shape of joining of Sealing (2), sealing surface (2) is provided with the potted line (3) that is no less than twice projection.
2. internal combustion locomotive engine cylinder sealing cushion for cover according to claim 1, is characterized in that: described sealing gasket be made as with by the corresponding shape of Sealing groove shape.
