Abstract

The invention discloses a steel structural member check valve which comprises a valve body, a valve element and a spring. The valve body is a steel structural member and is provided with a valve hole,the valve element comprises a valve rod and a main valve, the valve rod is arranged on the valve body in a sliding manner, the main valve is arranged at one end of the valve rod, and the valve and the valve rod are steel structural members and are integrally molded; the main valve is located outside the valve hole, one end of the spring is connected with the valve body, and the other end of the spring is connected with the valve rod; and in the initial state, under the effect of the spring, the valve seals one hole opening of the valve hole. According to the steel structural member check valve, the valve body, the valve and the valve rod are the steel structural member, the valve and the valve rod are integrally molded, the structure strength is large, deformation and destroying can be prevented from being caused, and the service life of the check valve is improved.

Description

technical field [0001] The invention relates to the field of check valves, in particular to a steel structure check valve. Background technique [0002] The check valve on the engine is installed in the oil pipeline of the engine. It opens in one direction under a certain pressure. After the engine oil pump stops working, the check valve can automatically close to prevent the engine oil from returning to zero. damage to components. Due to the complex working conditions of the engine, especially in high-power engines, due to the action of high temperature, high pressure and large flow of oil, the check valve is likely to be deformed and fail, and the check valve may also be damaged due to the backlog of oil after a long service life. failure or damage by external force. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any fo...
