Characteristics and maintenance methods of electric ash discharge ball valve
The ash unloading ball valve produced by Henan Shangvalve Co., Ltd. is divided into electric ash unloading ball valve, pneumatic ash unloading ball valve, turbine ash unloading ball valve, hydraulic ash unloading ball valve and other products according to different transmission modes. This series of products are mainly ideal equipment for controlling dust-containing gas, particle-containing liquid, powder and other media. The following is the electric discharge valve product features and maintenance.
The electric ash discharge ball valve is mainly used to cut off, distribute and change the direction of medium flow. It can rotate 90 degrees and can be closed tightly with a small rotating torque. Ball valves are suitable for switching and shut-off valves, but recent developments have designed ball valves to throttle and control flow. The electric ash unloading ball valve has simple structure and good sealing performance. The ball will pass the medium load to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the medium working load of the ball. This structure is widely used in medium and low pressure ball valves.

Product features of electric ash discharge ball valve:
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length. 4, easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 °, easy to remote control. 5, easy maintenance, pneumatic ball valve structure is simple, the seal ring is generally active, disassembly and replacement are more convenient. 6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface. 2. Simple structure, small size and light weight. 3, tight and reliable, the current ball valve sealing surface material widely used plastic, good sealing, in the vacuum system has also been widely used.
Maintenance of electric ash discharge ball valve: a. When reassembling the electric ball valve body, the bolts must be tightened symmetrically, gradually and evenly. B only when the pressure before and after the ball valve is removed, can the ball valve be disassembled and disassembled. c new parts should also be cleaned before assembly. d During assembly, metal chips, fibers, grease (except those specified for use), dust, other impurities, foreign matter, etc. shall not be allowed to contaminate, adhere or stay on the surface of the parts or enter the inner cavity. e After cleaning, the assembly shall be carried out after the wall cleaning agent is volatilized (it can be wiped with silk cloth without cleaning agent), but it shall not be left for a long time, otherwise it will rust and be contaminated by dust. f Non-metallic parts shall be removed from the cleaning agent immediately after cleaning, and shall not be soaked for a long time. g The decomposed individual parts can be cleaned by dipping. Metal parts with undecomposed non-metal parts can be scrubbed with clean fine and clean silk cloth impregnated with cleaning agent (to avoid fiber falling off and adhering to parts). All grease, dirt, glue and dust adhering to the wall shall be removed during cleaning. H in the decomposition of the ball valve and re assembly process, the need for sealing parts protection, especially non-metallic parts, such as O-rings and other parts of the best use of special tools. I The cleaning agent shall be compatible with the rubber parts, plastic parts, metal parts and working medium (such as gas) in the electric ball valve. When the working medium is gas, the metal parts can be cleaned with gasoline (GB484-89). Non-metallic parts are cleaned with pure water or alcohol.
Electric ash discharge ball valve is evolved from the globe valve. It has the same rotary 90-degree lifting action, except that the cock body is a sphere, with a circular through hole or passage through its axis. The ratio of the spherical surface and the channel opening should be such that when the ball rotates 90 degrees, the spherical surface should be present at the inlet and outlet, thus intercepting the flow. Suitable for blast furnace system, as the control of dust containing gas, containing liquid and solid powder and other media ideal equipment. The product has strong adaptability, and the sealing material is made of wear-resistant carbon fiber or high temperature resistant PPL material, which makes the service life of the product longer.
