Detailed Description
The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
The poppet valve centering device can be selectively provided with one or more centering devices according to the stroke length of the poppet valve. This patent simple structure, easily processing, stable in structure. The poppet valve centering device is made of carbon steel and comprises a centering piece base 1, a base support 2, a centering piece 3 and a centering piece pressing plate 4.
Centering member 3 include the three-layer PTFE axle lantern ring, every layer of PTFE axle lantern ring is formed by two semicircle ring concatenations, three-layer PTFE axle lantern ring concatenation position is crisscross each other. The centering piece base 1 is a steel plate with the thickness of 6mm, four wing plates are uniformly arranged on the periphery of the central circular steel plate, and bolt holes are formed in the central circular steel plate and the wing plates, as shown in fig. 3. Base supports 2 are respectively arranged above wing plates of the centering piece base 1 and are four angle steels with the angle of 40 multiplied by 4mm, one end of each base support 2 is welded on the wall of the equipment cylinder, and the other end of each base support is connected and fixed with the wing plates of the centering piece base 1 through angle steel bolts 8, angle steel nuts 9 and angle steel gaskets 10.
