Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As depicted in figs. 1 and 2: in order to enable the deflation effectively preventing engine high-temperature gas to liner, extending the service life of liner, reduce use cost, the present invention includes the cylinder 3 for receiving catalyst 7 and is installed on the liner 8 on cylinder 3 inwall；The upper end of described cylinder 3 is fixing with upper end cover 2 to be connected, and the bottom of cylinder 3 is fixing with bottom end cover 4 to be connected；Described upper end cover 2 bottom is provided with the crimping 9 turned up, and described crimping 9 is connected with upper end cover 2 by crimping connector 10, and the contact internal walls of the catalyst 7 in cylinder 3 and crimping connector 10, to form the contact sealing ring being used for stopping high-temperature gas deflation liner 8.
Specifically, catalyst 7 is positioned at cylinder 3, and with cylinder 3 in coaxial distribution, liner 8 is positioned at the outer ring of catalyst 7, and the height of liner 8 is lower than the height of catalyst 7, and namely catalyst 7 passes outside liner 8.Crimping 9 is along the marginal distribution of upper end cover 2 bottom, and crimping 9 and upper end cover 2 are in coaxial distribution, and crimping 9 is positioned at the outer ring of upper end cover 2, and crimping 9 is connected by the bottom of crimping connector 10 upper end cover 2.In the specific implementation, described crimping 9, crimping connector 10 are integral type structure with upper end cover 2.The upper end of cylinder 3 is contacted by crimping 9, the contact surface sealing surface in the form of a ring of cylinder 3 and crimping 9, and namely cylinder 3 is connected by crimping 9 is fixing with upper end cover 2.
Described crimping connector 10 is curved, and upper end cover 2 is connected by crimping 9 is fixing with cylinder 3；In cylinder 3, owing to the height of catalyst 7 is higher than liner 8, therefore, the upper end of catalyst 7 can contact with the lowermost end of crimping connector 10, and the contact surface of catalyst 7 top and crimping connector 10 in the form of a ring, can obtain contact sealing ring.Engine high-temperature gas enters in cylinder 3 by upper end cover 2, and described high-temperature gas is when catalyst 7, owing to contacting the effect of sealing ring, can make engine high-temperature gas will not deflation to liner 8 such that it is able to the effectively service life of prolongation liner 8.
Described upper end cover 2 is provided with upper flange 1, is provided with lower flange 5 on described bottom end cover 4, and described lower flange 5 is provided with flange bolt 6.In the embodiment of the present invention, upper end cover 2 utilizes upper flange 1 to be arranged on desired position, and bottom end cover 4 utilizes lower flange 5 and flange bolt 6 to be arranged on desired position.
