The invention discloses a sealed exhaust gasket with a semicircular tappet hole. The sealed exhaust gasket with the semicircular tappet hole comprises a gasket body, wherein a plurality of exhaust holes are formed in the gasket body side by side; a polytetrafluoroethylene coating is arranged on the inner wall of each exhaust hole; an upper positioning groove and a lower positioning groove are respectively formed in the two ends of the gasket body transversely; the lower edge of the gasket body between adjacent two exhaust holes extends outwards and is provided with a bulge; a mounting hole is formed in the bulge; the middle part of the front edge of the gasket body extends outwards and is provided with a semicircular bulge; the semicircular tappet hole is formed in the semicircular bulge. According to the sealed exhaust gasket with the semicircular tappet hole, the tappet hole is novel in design; the positioning grooves achieve the effects of positioning and stabilizing; the polytetrafluoroethylene coatings achieve the effects of sealing and resisting abrasion; therefore, the service life of the gasket is favorably prolonged.
Description
technical field [0001] The invention mainly relates to the gasket field, in particular to a sealing exhaust gasket with a semicircular tappet hole. Background technique [0002] At present, most of the sealing devices used in mechanical systems are generally sealed with rubber rings. When performing end face sealing, it is necessary to set grooves or corners for fixing the rubber ring on the parts, otherwise the rubber ring is not easy to fix. In this way, the manufacturability of the apron seal is relatively complicated, the anti-vibration ability is weak, the pressure of the carried liquid is low, and the sealing effect is not strong. Contents of the invention [0003] The object of the present invention is to provide a sealing exhaust pad with a semicircular tappet hole in order to remedy the defects of the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A sealed exhaust pad with a semicircular tappet hole...
