Description
Technical field
The utility model relates to oil cylinder auxiliary member technical field, especially a kind of oil cylinder gudgeon mounting structure.
Background technique
Gudgeon mounting type ball valve for pipeline usually have band body cavity valve body, be rotatably arranged on gudgeon mounting type ball in body cavity and two seat rings that independently float, described floating seat ring has corresponding valve seat, and described valve seat guarantees the two-way tightness of valve.First seat ring is arranged for guaranteeing the tightness between pipeline and body cavity, and the second seat ring provides and arranges for guaranteeing the sealing between wiper chamber and body cavity.
In order to prevent the premature wear of the valve seat of seat ring, the opening and closing of valve should pressure in pipeline, wiper chamber and body cavity in a basic balance time carry out.This needs the secondary circuit for balancing the pressure in body cavity usually.This secondary circuit adds cost and the complexity of valve, and also also add the complexity of valve operation.
Model utility content
In order to overcome the deficiency of existing technology, the utility model provides a kind of oil cylinder gudgeon mounting structure.
The utility model solves the technological scheme that its technical problem adopts: a kind of oil cylinder gudgeon mounting structure, comprise gudgeon and trunnion base, described gudgeon intermediate section is provided with and oil cylinder end face suitable cambered surface mutually, and gudgeon two ends are provided with nut bore one, and it is convex that the port of nut bore one both sides is provided with tooth; Described trunnion base is T-shaped, and upper end is provided with nut bore two, and port, described nut bore two both sides is provided with groove.
According to another embodiment of the present utility model, comprise further, the base of described trunnion base is provided with perforate.
The beneficial effects of the utility model are, gudgeon of the present utility model coordinates closely with trunnion base, provide protection against wear, and the support of trunnion base is firm, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model trunnion configuration schematic diagram.
Fig. 2 is the utility model trunnion base structural representation.
In figure 1, gudgeon, 2, trunnion base, 11, cambered surface, 12, nut bore one, 13, tooth be convex, 21, nut bore two, 22, groove, 23, perforate.
Embodiment
As shown in Figure 1, 2, a kind of oil cylinder gudgeon mounting structure, comprises gudgeon 1 and trunnion base 2, and described gudgeon 1 intermediate section is provided with and oil cylinder end face suitable cambered surface 11 mutually, and gudgeon 1 two ends are provided with nut bore 1, and the port of nut bore 1 both sides is provided with tooth convex 13; Described trunnion base 2 is T-shaped, and upper end is provided with nut bore 2 21, and port, described nut bore 2 21 both sides is provided with groove 22.The base of described trunnion base 2 is provided with perforate 23.
During installation, the cambered surface 11 of gudgeon 1 is relative with oil cylinder end face, and tooth convex 13 is relative with the groove 22 of trunnion base, and groove 22 adds seal ring, then seals fastening by convex for tooth 13 with groove 22 by nut bore 1.Such tooth male structure and seal ring can reduce the wearing and tearing of gudgeon and trunnion base.Trunnion base 2 is T-shaped, is convenient to stable placement, and on bottom surface, establishes perforate 23, for strengthening fastening trunnion base.
