Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic vacuum belt inflation valves, in particular to an electromagnetic vacuum belt inflation valve which is convenient to connect. Background Art

[0002] The electromagnetic vacuum belt charging valve is a mechanical vacuum pump safety valve installed at the air inlet of the mechanical vacuum pump and opened and closed synchronously with the pump. When the pump stops working or the power is suddenly interrupted, the valve automatically closes to keep the vacuum system vacuum and fill the pump cavity with air, thereby avoiding reverse flow of pump oil and contamination of the vacuum system. The applicable medium is pure air and non-corrosive gas. In order to improve the safety of the use of mechanical vacuum pumps, an electromagnetic vacuum belt charging valve is needed, but the existing electromagnetic vacuum belt charging valve still has the following shortcomings:

[0003] For example, the utility model with application number 201820548282.2 discloses an electromagnetic vacuum belt inflation valve. The utility model cooperates with a first compression spring, a spring upper sleeve, a steel ball, an elastic cylindrical pin, a steel ball sleeve and a sealing cover component. The first compression spring is limited by the sealing cover component and the spring upper sleeve to provide a force when the valve is closed. The steel ball is positioned by the steel ball sleeve, so that the steel ball can roll and rotate while maintaining its position unchanged, thereby reducing the friction generated by the movement of the armature, improving the stability of the electromagnetic vacuum belt inflation valve, and ensuring the service life of the electromagnetic vacuum belt inflation valve. However, similar to the comparative documents of the above-mentioned application, when the existing electromagnetic vacuum belt inflation valve is used, since most electromagnetic vacuum belt inflation valves are threadedly connected through flanges, the connection process is time-consuming and labor-intensive and inconvenient for subsequent repair and maintenance, resulting in reduced practicality and reduced use efficiency of the electromagnetic vacuum belt inflation valve.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an electromagnetic vacuum belt inflation valve with easy connection is proposed. Utility Model Content
