Abrasion and ceramic discharge gate valve is suitable for the severe slurry pipeline, and solid particles and the larger particles with more severe conditions, such as catalytic cracking system of petrochemical industry, power plant ash water piping. seal adopts high performance engineering structural ceramics, wear-resisting, corrosion resistance, long life. The body and the outlet at the bottom of the ceramic Mosaic structure has greatly increased the resistance to scour capability of the valve. Body outlet slag mouth of optimization design, realizing the body at the bottom of the slag, the valve closed tightly. body cavity can be achieved through special processing antiscale and corrosion, wear etc. Characteristics. Applicable to the nominal pressure PN1. 6 to 32. 0 mpa and P54170V, working temperature - 29 ~ 540 ℃ in the petroleum, chemical, mining, metallurgy, electric power industry, such as the pipeline under various working conditions, cut off or connect pipe medium. Especially for ash discharge, the discharge system, feeding, sewage system, the service life of more than 10 times higher than that of ordinary alloy valve sealing surface. Wear-resistant ceramic discharge gate valve body with carbon steel ( WCB) Lining material, USES the ZTA engineering ceramics. Is mainly used in the ore pulp and ash slurry, etc. According to different working condition can be driven by different ways, there is electric, manual and bevel gear transmission. Connection mode usually use flange connection. The characteristics of 1. Bi-directional shunt structure design, more pressure discharge engineering ceramics slurry valve is designed for industrial and mining medium solid-liquid two-phase flow pipeline design and manufacture, possess + shut off on or off the throttle of dual function, compared with the conventional slurry valves, more targeted, more pressure; 2. Choose toughening ceramic materials, more wear-resisting the ceramic discharge slurry valve adopts double sealed, achieve the result of double wear-resisting, Industrial Valves cavity flushing flow inside lining has a ceramic piece, compared with the conventional discharge slurry valves, more wear-resisting, corrosion resistance, impact resistance, long service life; 3. Protect a lip patent technology, ceramic seal ring shear crack prevention seat diameter in protective lip ( Patent) Structure, which can effectively prevent the Industrial Valves from the inner diameter person when they are about to close for the shear crack ceramic seal ring. 4. Escalating drive way, more convenient use manual, electric, bevel gear drive drive a variety of ways, to meet different customer needs, electric drive valve can effectively realize the remote control and opening instructions, used if throttling valves opening distance adjustment error can be controlled in 1. 00 mm, runtime self-locking performance is good. Structure features: all parts in contact with the medium for structural ceramics material, and the chemical stability of high hardness, Rockwell hardness HRC90) , second only to diamond. Therefore, this valve has a very high wear resistance, corrosion resistance, erosion resistance, good insulating and stays, small thermal expansion. Ball manufactured grinding equipment and advanced technology, high precision ball roundness, good surface quality, and the seat of research, using Zr02 ceramics from smooth sex, can achieve good sealing performance.
is a must have for anyone who appreciates cast iron gate valve to the greatest extent.
