Plate valve butterfly valve products
The heavy-duty ash unloading valve / double-layer heavy-duty ash unloading valve is a hopper discharge device for various types of removal equipment and a feeding and discharging device for various mills, dryers, silos and other equipment to prevent wild wind from blowing in. Runtian Environmental Protection's heavy-duty ash unloading valve / double-layer heavy-duty ash unloading valve adopts steel plate welding structure, self-resetting mechanism of counterweight rod, compact structure, stable and reliable work.
The double-single-door electric air-lock flap valve plate has two sealing surfaces.The two sealing surfaces of the more commonly used mode gate valve form a wedge shape, and the wedge angle varies with the valve parameters, usually 50. The ram can be made as a whole, called a rigid ram.
Manually inserted plate valves are mostly used in unloaders and are divided into square and round ports. Its compact structure, wear resistance, small leakage, easy operation, flexible operation, labor saving, etc., can work normally in high temperature, high dust, strong magnetic environment, the mouth shape should be selected according to the shape of the unloader. Welded with high quality carbon steel, widely used in metallurgy, carbon, chemical, building materials and other industries. Mostly used for flue gas regulation and switching in flue gas pipeline system of flue gas purification system.
The electric plug-in valve is a valve in which the gate and the valve seat are always in close contact and sealed. The opening and closing part of the electric plug-in valve is a shutter, and the movement direction of the shutter is perpendicular to the fluid direction. The electric plug-in valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the more commonly used mode gate valves form a wedge, and the wedge angle varies with the valve parameters.
The casing test and sealing test medium of the flapper valve are water (containing preservatives), kerosene or other suitable liquids with a viscosity not greater than water. The sealing pair is a non-metal sealed plug-in valve. The test and requirements of the sealed housing are in accordance with GB / T13927-92 Class D regulations. The sealing pair is a metal-sealed plug-in valve. For those with sealing performance requirements, the leakage of the sealing test is calculated as 1 × DNmm / s. If there is no sealing performance requirement, this test will not be performed.
The LMS two-way plug-in valve has a simple structure, flexible operation, light weight, and no jamming. It is especially suitable for the transportation and flow adjustment of various solid materials and about 50mm block and lump materials. Can adjust the scale at any time, can be operated in both directions, and is simple and flexible. Widely used in metallurgy, mining, building materials, food, chemical and other industries to control flow changes or quickly cut off. Materials are carbon steel and stainless steel, and various non-standard spiral gates can be customized according to customer needs.
