is located at the lakeside of beautiful Lake Tai and at the foot of
Mount Long, with newly-built Taihu Road (only way to the Grand Buddha
at Ling Shan) and Huyi Highway in the nearby, easily accessible.
Changzhou Kairun Machinery co.,ltd., as a manufacturer devoted to
R&D of pneumatic conveying equipment and owning a good many advanced
technologies, is specialized in manufacturing a variety of ceramic
valves, wear-resistant valves, special type valves, power station
valves, and spare parts for fly ash system of thermal power plant.
The company owns many middle-level and senior technicians and advanced
manufacturing, testing and inspection instrumentations.
Pneumatic conveying is a mode with materials and pressure, which
produce big impacts on and bring big wear to valves that are a key
part of the pneumatic conveying system. Ideal valves shall have the
advantages of strong wearability, good stability and long service
life; however,currently valves in widespread use in the pneumatic
conveying industry are of bad wearability and stability. The average
service life of home-made valves is three months or so and that of
imported valves is half a year to one year either, which needs frequent
replacement of valves during production, thus both affecting benefits
and increasing operation cost. Aiming at this, Changzhou Kairun Machinery
co.,ltd., after repeated researches and testing by all technical personnel
and with hard efforts of all employees, has successfully developed
“PG double-disc air-lock wear-resistant ceramic valve” and “wear-resistant
rotary valve”, which enhance the sealing performance of valve core
and seat, reduce wear and prolong the service life of valves (generally
1-3 years) so that they can completely supersede imported valves with
proper price and a wide range of service temperature.
The valves are mainly used for opening and closing of charging and
discharging of gas and slag in dry ash system of power plant, and
also applicable for opening and closing of such media as wear and
corrosion-resistant fine dust, water, oil and vapor at tube edge in
the industries of mining, paper-making and petrochemical etc. PG double-disc
air-lock wear-resistant ceramic valve has the advantages of good sealing
property, high temperature resistance, strong wearability, easy starting,
no ash deposit and long service life.
