Problems solved by technology

But when the water medium replaces the mineral oil as the working medium, the water pressure relief valve designed based on the traditional oil pressure relief valve design theory will be inconsistent with the hydraulic system, causing the valve and even the entire hydraulic system to work unstable

Abstract

The invention relates to a hydraulic one-way valve. The hydraulic one-way valve comprises a valve body, a valve element, a spring and a check ring, wherein the valve body is provided with a specific internal fluid channel which extends along the axis of the valve body; the valve element is arranged in the valve body; the spring is located in the valve element and used for abutting against the valve element; and the check ring is used for limiting the spring. A water inlet is formed in the lower end of the valve body in the axis direction of the valve body. A water outlet is formed in the upper end of the valve body in the axis direction of the valve body. A valve element protection rod is arranged at the front end of the valve element, the valve element protection rod is a cylindrical rod, and an arc-shaped groove is formed in the front end face of the valve element protection rod. When the hydraulic one-way valve is in use, water flow flows from the water inlet to the water outlet; since the valve element protection rod is arranged on the front end face of the valve element, the valve element can be effectively protected against damage; and meanwhile, the arc-shaped groove is formed in the front end face of the valve element protection rod so that the flowing direction of the water flow can be changed, the momentum of the water flow is reduced, and the cavitation resistance of the valve element protection rod is improved.

Description

technical field [0001] The invention relates to the technical field of valve components, in particular to a hydraulic one-way valve. Background technique [0002] Hydraulic technology is a new technology that uses natural fresh water, sea water or tap water instead of mineral oil as the working medium of the hydraulic system. Like oil pressure technology, it belongs to hydraulic transmission technology. In the development process of hydraulic transmission technology, water has played a very important role as the medium of power transmission, exchange and control. Today, when resources are scarce and environmental protection is advocated, the application of water as the working medium of hydraulic transmission technology has the following advantages: 1. Eco-friendly, environmental protection and pollution-free; 2. Clean and safe, can avoid fire; 3. Low price and wide source ; 4, easy to maintain and maintain. [0003] As one of the core components of hydraulic transmission ...
