BJ41W-Stainless steel heat insulation globe valve product structure characteristics 2. It adopts the middle flange thread connection, the two ends of the branch pipe are flange connection structure, which can be used with imported equipment. 3. The sealing surfaces of the valve disc and the valve seat are made of stellite cobalt-based hard alloy, which is hard-wearing and 4. The valve stem is quenched and tempered and the surface is nitrided.
■ The opening and closing parts of BJ45W jacket insulation stop valve are plug-shaped discs, the sealing surface is flat or conical, and the discs move linearly along the center line of the fluid. The movement of the valve stem can be lifted (the stem is raised and lowered, and the hand wheel does not rise and fall), and there is also a lifted rotary lever (the hand wheel is rotated and raised together with the stem, and the nut is provided on the valve body)

PPC air box pulse dust remover structure and working principle: PPC bag dust remover is composed of shell (usually welded by 5mm carbon steel plate), bracket and pulse dust cleaning system, ash bucket, ash discharge device and other components. When the dust-containing gas enters the PPC air box pulse bag filter from the air inlet, it first encounters the inclined partition in the middle of the air inlet
Insulation globe valve is mainly used in petroleum, chemical, metallurgy, pharmaceutical and other systems to transport high-viscosity media that will solidify at normal temperature. It is a BJ45W DC jacket insulation globe valve. Between the flanges, two connection ports of the insulation jacket are provided on the side and bottom of the valve. DC protection
Structure of globe valve: 1. Types of globe valve are divided into external thread type and internal thread type according to the position of the stem thread. According to the flow direction of the medium, there are straight-through, direct-current and angular. The shut-off valve is divided into sealing forms, and it has a packing-sealed shut-off valve and a bellows-sealed shut-off valve. 2. The structure of the valve body is straight through
