Embodiment
For further setting forth the 26S Proteasome Structure and Function of the utility model, below in conjunction with accompanying drawing and preferred embodiment the utility model is elaborated, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
Fig. 1 is the partial structurtes sectional view of the said diesel engine thermoregulator of the utility model; Shown in figure, this thermoregulator includes valve seat 1, support 6 and is installed in the inductor 7 in the valve seat 1, on this inductor 7, is provided with major cycle valve 4; Outer rim at this valve seat 1 is provided with sealing gasket 3; Outer rim at this major cycle valve 4 is provided with the seal ring 2 that cooperates with valve seat 1 internal surface, and this valve seat 1 is the taper cover-shaped structure, and the internal surface at this valve seat 1 middle part is provided with the convex rib structure that distributes ringwise; Major cycle valve 4 and seal ring 2 cooperate with the lower edge of this convex rib structure, are provided with in the bottom of this valve seat 1 and support 6 flange connecting dishes.Seal ring 2 is installed on the major cycle valve 4, improving sealing between major cycle valve 4 and the valve seat 1, and minimizing thermoregulator body 13 self internal coolant leakage rate.Inductor 7 is connected with valve seat 1 through major cycle valve 4 intermediate holes; Return spring 5 is enclosed within inductor 7 end portions, is installed in major cycle valve 4 lower end surfaces, and support 6 puts the inductor 7 that installs return spring 5 and couples together with valve seat 1.Limit spring 8 is installed in inductor 7 bottoms, short circle valve 9 be right after be installed in below, caudal peduncle 10 is installed in below the warm device short circle valve 9 and is integrally welded with inductor 7.Sealing gasket 3 is enclosed within on the outer rim of valve seat 1 bottom flange plate, upper and lower, the cylindrical of sealing gasket 3 respectively be provided with the small semicircle convex tendon with improve between thermoregulator 13 and the thermolator base 14, thermoregulator 13 covers between 12 with thermoregulator, thermolator base 14 and thermoregulator cover the sealing between 12.
