Abstract

The invention discloses a manufacturing method of a high temperature and high pressure resistant hydraulic component. The hydraulic component comprises a mounting shell, one end of the shell is provided with a valve hole, and the other end of the mounting shell is provided with a threaded hole which is communicated with the valve hole and is coaxial. The valve hole is provided with a valve core that fits with the valve hole. The clearance between the valve core and the valve hole is 0.001‑0.002mm. The roughness of the inner surface of the valve hole and the outer surface of the valve core are Ra0.4 and Ra0 respectively. .2; and prepared through the steps of material preparation, heat treatment, machining, fitter, surface treatment, grinding, and testing, the valve core and the valve hole can be sealed and fitted in a medium environment of 120‑130℃ and a pressure of 40‑45MP It has good sealing performance, and the preparation method of the present invention has a high yield.

Description

technical field [0001] The invention belongs to the technical field of hydraulic control components, and relates to a manufacturing method of a hydraulic component resistant to high temperature and high pressure. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, regulate and control the conveying medium. The sealing structure of the valve is mainly divided into two types: hard seal and soft seal. Hard seal mainly refers to the use of metal structure for sealing, and soft seal is to use metal and non-metallic materials to seal, and according to the sealing form, there are surface seal, Cone seal, ball seal, etc. [0003] When the medium temperature in the system is not high, many soft sealing structures are used, but when the medium temperature is high (> 500 ℃), the selection of non-metallic materials is extremely difficult, for example: high-pressure sealing materials Such as graphite packin...
