Brief description of the drawings
Fig. 1 is the structure diagram according to a preferred embodiment of the integrated form valve body of the utility model.
Fig. 2 is the structure diagram according to preferred embodiment middle casing shown in Fig. 1 of the integrated form valve body of the utility model.
Embodiment
It is that the following description is substantially merely exemplary and be not intended to the limitation disclosure, application or purposes.Below
The embodiment of the integrated form valve body of the utility model is further described with reference to Figure of description.
As shown in Figure 1 and Figure 2, according to the utility model integrated form valve body structure diagram.
The integrated form valve body of the utility model, including housing 1 and pressure adjusting structure, the right side of the housing 1 are equipped with cavity knot
Structure 24 (such as Fig. 2), the pressure adjusting structure are placed in cavity structure 24.Pressure adjusting structure and housing 1 are effectively combined, structure is more stepped up
Gather, appearance and size is farthest reduced compared with Split type structure, and realize that function integrates.
In the present embodiment, the pressure adjusting structure includes valve 3, piston 5, valve seat 6, relief piston 7 and pressure spring 9.
In the present embodiment, the end of the valve 3 is equipped with spring 2.
