Pneumatic wear-resisting ceramic rotary deslagging valve

Abstract

The invention relates to the technical field of valve equipment, in particular to a pneumatic wear-resisting ceramic rotary deslagging valve. The pneumatic wear-resisting ceramic rotary deslagging valve comprises a pneumatic mechanism, an outer rocker arm, a rotary shaft component, a rotary shaft sleeve, an upper valve body, an inner rocker arm, a spring seat, a valve plate and a lower valve body;the upper valve body and the lower valve body are in fixed and sealed connection, the pneumatic mechanism is connected with the outer rocker arm, the outer rocker arm is connected with the inner rocker arm, and the inner rocker arm is connected with the valve plate through the spring seat; the rotating shaft component comprises a rotating shaft, the upper end of the rotating shaft is fixedly connected with the outer rocker arm, the rotating shaft is arranged in the rotating shaft sleeve, and the rotating shaft sleeve is arranged on the upper valve body; the lower end of the rotating shaft isfixedly connected with one end of the inner rocker arm; the other end of the inner rock arm is fixedly connected with the spring seat, a mold spring is arranged at the bottom in the spring seat, and the valve plate is connected with the spring seat through the mold spring. The pneumatic wear-resisting ceramic rotary deslagging valve disclosed by the invention is reasonable in structure, has the advantages of being resistant to wear and high heat and long in service life, and is suitable for various dust and particle conveying systems of thermal power plants, metallurgy, medicine, chemical engineering and the like.

Description

technical field [0001] The invention relates to the technical field of valve equipment, in particular to a pneumatic wear-resistant ceramic rotary slag discharge valve. Background technique [0002] At present, the valves used in various dust and particle conveying systems in thermal power plants, metallurgy, and chemical industries are generally made of carbon steel or wear-resistant steel. Due to the continuous erosion of powder particles, the sealing ring and valve plate are easily damaged. Abrasion, poor sealing performance and wear resistance, resulting in ash leakage, air pollution, environmental pollution, and often ash and jamming. Finally, the entire valve is scrapped, which not only increases the maintenance cost of equipment, but more importantly, affects safe production. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a pneumatic wear-resistant ceramic rotary slag discharge valve with reasonable struct...

Problems solved by technology

[0002] At present, the valves used in various dust and particle conveying systems in thermal power plants, metallurgy, and chemical industries are generally made of carbon steel or wear-resistant steel. Due to the continuous erosion of powder particles, the sealing ring and valve plate are easily damaged. Abrasion, poor sealing performance and wear resistance, resulting in ash leakage, air pollution, environmental pollution, and often ash and jamming

In the end, the entire valve is scrapped, which not only increases the cost of equipment repair and maintenance, but more importantly, affects safe production.
