Problems solved by technology

[0003] When the dome valve handles abrasive materials, the expandable pressure sealing ring embedded in the dome valve seat ensures the working pressure difference between the front and rear of the valve. The action material particles slide, which will wear the valve seat and sealing ring. The existing dome valve structure is too simple, large in size, poor in sealing performance, not wear-resistant, short in service life, and not wide enough in scope of application.

Abstract

The invention discloses a novel dome valve and relates to the technical field of valves. A driven shaft (2) is arranged in a valve body (1), a top plate (3) is arranged at the upper end of the valve body (1), an expandable sealing ring (4) is arranged in the top plate (3), an arched valve clack (5) is arranged in the middle of the valve body (1), the driven shaft (2) is connected with a driving shaft (6), a proximity switch (7) is arranged on one side of the valve body (1), one end of the valve body (1) is connected with a double-acting air cylinder (8), and an outlet connector (9) is arranged at the lower end of the valve body (1). The novel dome valve is compact in structure, convenient to use, small in size, light, good in sealing effect, resistant to wear and corrosion, long in service life, suitable for processing dusty gas and erosiveness bulk materials and wide in application range.

Description

Technical field: [0001] The invention relates to the technical field of valves, in particular to a novel dome valve. Background technique: [0002] Due to its special structure, the dome valve is usually the preferred valve in pneumatic conveying. The dome valve can cut off the flowing material flow or static material column entering the pressure tank, and then close to achieve sealing, so as to ensure that the filling rate of the pressure tank is 100%. %, and does not need to rely on the level gauge of the sending tank, so the control principle is simple and reliable. [0003] When the dome valve handles abrasive materials, the expandable pressure sealing ring embedded in the dome valve seat ensures the working pressure difference between the front and rear of the valve. The particles of the action material slide and wear the valve seat and sealing ring. The existing dome valve has a simple structure, large volume, poor sealing performance, non-wear resistance, short s...
