Pneumatic wear-resistant ceramic rotary slag valve

Abstract

The invention relates to the technical field of valve equipment, in particular to a pneumatic wear-resistant ceramic rotary slag discharge valve, which includes a pneumatic mechanism, an outer rocker arm, a rotating shaft assembly, a rotating shaft sleeve, an upper valve body, an inner rocker arm, a spring seat, a valve plate and a lower valve body. The valve body, the upper valve body and the lower valve body are fixed and sealed, the pneumatic mechanism is connected with the outer rocker arm, the outer rocker arm is connected with the inner rocker arm through the rotating shaft assembly, and the inner rocker arm is connected with the valve plate through the spring seat; the rotating shaft The assembly includes a rotating shaft, the upper end of which is fixedly connected to 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 is fixedly connected to one end of the inner rocker arm; the other end of the inner rocker arm It is fixedly connected with the spring seat, and the bottom of the spring seat is provided with a mold spring, and the valve plate is connected with the spring seat through the mold spring. The invention has reasonable structure, wear resistance, high heat resistance, and long service life. Power plant, metallurgy, medicine, chemical industry and other dust and particle conveying systems.

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.
