As further improvement, described fixing protective plate is all identical with the degree of depth of counterbore with the thickness of activity protective plate, and the area of activity protective plate is greater than the area of medium through hole.
As further improvement, described hinge-lid type protective plate is the overall structure that fixing protective plate and activity protective plate utilize pin to connect into, the integrally-built shape of hinge-lid type protective plate is circular or rectangle, and the counterbore namely on media cavity limiting board is corresponding circle or rectangle.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model adopts hinge-lid type protective plate, the wearing and tearing of its moving part are only limitted to the Small-angle Rotation friction between pin and activity protective plate column pin hole, overcome existing protecting and the axis of guide and pilot hole easily weares and teares, working life is short weakness occur when template is used in reciprocating pump, wear-out period is longer than and adopts existing protective plate, solve the defect that existing protective plate is not suitable for reciprocating pump; Also make the utility model that have employed hinge-lid type protective plate, its stability and reliability significantly improve simultaneously.
2, the thickness of hinge-lid type protective plate in the utility model, consistent with the counterbore degree of depth of media cavity limiting board, when activity protective plate is in closed condition, the media cavity inwall on media cavity limiting board forms burnishes, is not easy breakage when diaphragm is close to this surface.
3, in the utility model, the surface of contact of the opposite side of hinge-lid type protective plate and media cavity limiting board counterbore surface is comparatively large, have structural strength high, the large advantage of thrust can be born, also to playing better protective action the working life extending diaphragm.
