Fig. 1 is a sectional view of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.
Referring to fig. 1, a miniature plug formula check hydraulic valve, including valve body 1, steel ball 2, valve cap 3 and spring 4, be equipped with the fluid hole 11 of undergauge on the valve body 1, side play oil opening 10, valve cap 3 fixed connection is in fluid hole 11, and the one end of spring 4 supports on valve cap 3, and the other end supports on steel ball 2, and fluid hole 11 includes major diameter section 12 and path section 13, major diameter section 12 diameter is greater than the diameter of steel ball 2, and the diameter of path section 13 is less than the diameter of steel ball 2, the periphery of valve body 1 is equipped with the external screw thread, and the tip of valve body 1 has flange 14. The side oil outlet gap 10 is arranged on the large-diameter section 12.
Referring to fig. 1, an axial groove 5 is formed in the inner side of the flange edge 14 of the valve body 1, and an ED sealing ring 6 is arranged in the axial groove 5. The valve body 1 is of a cylindrical structure and is convenient to assemble with an external connecting part, and the ED sealing ring 6 can ensure the sealing performance after installation.
Referring to fig. 1, a radial clamping groove 15 is formed in the inner wall of the large-diameter section 12 of the oil hole 11, and a clamping ring 31 is arranged on the bonnet 3, and the clamping ring 31 is clamped on the radial clamping groove 15. During installation, the clamping ring 31 of the valve cap 3 is clamped on the radial clamping groove 15, and the installation efficiency is improved.
Referring to fig. 1, a boss 32 is provided on the bonnet 3, and one end of the spring 4 is sleeved on the boss 32. The boss 32 ensures the centering degree of the spring 4 after installation, and the other end can just abut against the central position of the steel ball 2.
Referring to fig. 1, the joint of the large diameter section 12 and the small diameter section 13 of the oil hole 11 has a bevel transition section 16. The peripheral surface of the steel ball 2 is matched with the inclined plane transition section 16, so that the sealing performance is ensured.
The utility model discloses a theory of operation: referring to fig. 1, when hydraulic oil enters an oil hole 11 from the lower part, the steel ball 2 is pressed upwards, the spring 4 is pressed by the steel ball 2, the hydraulic valve is opened, and the hydraulic oil flows upwards from the side oil outlet gap 10 of the valve body 1. When the side hydraulic oil enters the oil liquid hole 11 through the side oil outlet gap 10, the steel ball 2 is squeezed more tightly. The steel ball 2 is propped against the inclined plane transition section 16, the hydraulic valve is in a closed state, and hydraulic oil cannot pass through the hydraulic valve.
