Problems solved by technology

However, hydraulic oil has two serious disadvantages of being flammable and polluting the ecological environment, which made hydraulic transmission lose its application in industries such as food, medical equipment, electronics, and packaging during the 1950s and 1980s.

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] In the present invention, water is used as the working medium. The hydraulic technology is a new technology that replaces mineral oil with natural fresh water, sea water or tap water as the working medium of the hydraulic system. Like the oil pressure technology, it belongs to the 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:

[0027] 1. Eco-friendliness, environmental protection and pollution-free With th...

Abstract

The invention discloses a novel overflow valve. The novel overflow valve comprises a valve body, a valve core, a valve seat, a valve cover, an adjusting stud, an adjusting nut, an adjusting cap, a flange, a left spring seat, a right spring seat and a spring, wherein the valve core comprises five sections which are a hemispherical section, a circular truncated cone-shaped section A, a cylinder connection section, a circular truncated cone-shaped section B and a guide cylinder section from the left part to the right part in sequence; a hemispherical groove is formed in the outer surface of the circular truncated cone-shaped section A; a radial through-flow hole A and a radial through-flow hole B are formed in the cylinder connection section; the radial through-flow hole A and the radial through-flow hole B are vertically formed in the cylinder connection section; a guide circular groove is formed in the guide cylinder section; an axial through-flow hole is formed in the valve core in the center line direction; one end of the axial through-flow hole is communicated with the outer part of the guide cylinder section, and the other end of the axial through-flow hole is communicated with the radial through-flow hole A; an elastic gasket is mounted in a position where the valve seat is connected with the valve cover. The novel overflow valve can reduce gas etching, lower vibration and noise, and improve the sealing performance.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to an overflow valve suitable for medium and high pressure water hydraulic systems using seawater, fresh water, high water base, etc. as working media, and in particular to a novel direct-acting overflow valve. Background technique [0002] Water hydraulic technology is a new technology that replaces mineral oil with natural fresh water, sea water or tap water as the working medium of the hydraulic system. In the development process of hydraulic transmission technology, water has played a very important role as the medium of power transmission, exchange and control. Hydraulic transmission, which first used water as the medium of power transmission, exchange and control, appeared at the end of the seventeenth century. In the following hundred years, the medium of hydraulic transmission has been water. Hydraulic transmission has been used as a powerful and indispensable t...
