The ceramic double gate valve in the
Hardware Material is also called the ceramic parallel double gate valve or the dry ash valve, which is a kind of ceramic gate valve. Therefore, its
Structural Parts and working principle are consistent with the ceramic gate valve, and its opening and closing body (valve plate) is lifted by the valve stem to move the sealing surface of the valve seat, which can be connected or cut off the fluid channel. When the valve is partially opened, the back of the gate produces eddy currents, which is easy to cause the flushing and vibration of the gate, easy to damage the sealing surface of the valve seat, and difficult to repair. Generally, it is suitable for situations where it is not necessary to frequently open and close and keep the ram fully open or fully closed.
Ceramic double gate valve
Ceramic double-gate valve is mainly used for the discharge and transportation of dry powder Materials into the
Building Materials pipeline, as a channel to cut off and enter the medium, so the discharge valve, balance valve, exhaust valve, drainage valve of the warehouse pump can also be used as a switch valve and ash discharge valve of the pipeline. It has the characteristics of good sealing performance, small starting load, less ash card and ash accumulation, wear resistance, long service life and so on.
Ceramic double-gate valves are usually connected with flanges and can be divided into manual and electric two types. Specifically, the range of use of this series of products: power plant ash - dry ash system; 2. Selection and transportation of dry powder materials in concentrator; 3. Cement industry - dry powder transportation and unloading; Flour mill - flour conveying pipe.
Performance comparison:
Toughened ceramic material, more wear-resistant!
Engineering ceramics are used as anti-erosion materials
Compared with the conventional gate valve, more wear-resistant, high pressure resistance, impact resistance, long service life
Unique structural design, more reasonable;
The structure of bidirectional prepressure and rotating self-sealing of gate is designed.
The sealing surface is worn evenly in the dry powder medium, and has excellent sealing performance and long service life during frequent opening and closing.
The design has a clean ash port for easy cleaning or servicing of the valve when in use.
