There are several commonly used globe valves: 1) Straight-through globe valve 2) DC globe valve: In the DC or Y-type globe valve, the flow path of the valve body is inclined with the main flow path so that the degree of destruction of the flow state Than the regular valve to be small, so the pressure loss through the instrument valve is also a small. 3) Angle stop valve: In the angle stop valve, the fluid only needs to be changed in one direction, so that the pressure drop through this gauge valve is smaller than that of the conventional structure. 4) Plunger globe valve: This type of globe valve is a variation of a conventional globe valve. In this instrument valve, the valve disc and valve seat are usually designed on the principle of plunger. Polished valve plunger into a plunger connected with the stem, the seal is set by the plunger in the two elastic ring to achieve. The two elastomeric seals are separated by a collar, and the seal around the plunger is pressed firmly by the load exerted by the bonnet nut on the bonnet. Elastomer seals are interchangeable and can be made from a wide variety of materials. The meter valve is intended primarily for "on" or "off," but with a special form of plunger or special collar that can also be used to adjust flow. Globe Valve Selection Guide Stop valve stem axis and seat sealing surface perpendicular. Valve stem opening or closing stroke is relatively short, and has a very reliable cut off action, making this instrument valve is very suitable as a medium cut off or adjust and throttle use. Once the valve flap of the globe valve is in the open condition, its valve seat and valve flap seal face no longer contact with each other, and has a very reliable cut-off action. The instrument valve is suitable for this as a medium to cut off or adjust and Throttle use. Once the stop valve is open, its valve seat and disc seal surface no longer have contact between, and therefore its sealing surface mechanical wear and tear less, as most of the valve seat and the disc valve is relatively easy to repair or replacement Sealing components eliminates the need to remove the entire meter valve from the pipeline, which is a good fit for instrument valves and pipe welding. The flow direction of the medium as it passes through such meter valves has changed, so the flow resistance of the shut-off valves is higher than that of other meter valves. There are several commonly used stop valves: 1) Angle stop valves; in angle stop valves, the fluid only needs to be changed once, so that the pressure drop across the gauge valve is smaller than that of the conventional stop valve. 2) DC-type globe valve; In the DC or Y-type valve, the body of the flow path and the main flow into a slash, so that the flow of state damage than conventional stop valve is smaller, so the pressure loss through the instrument valve is also The corresponding small. 3) Plunger globe valve: This type of globe valve is a variation of a conventional globe valve. In this instrument valve, the valve disc and valve seat are usually designed on the principle of plunger. Polished valve plunger into a plunger connected with the stem, the seal is set by the plunger in the two elastic ring to achieve. The two elastomeric seals are separated by a collar, and the seal around the plunger is pressed firmly by the load exerted by the bonnet nut on the bonnet. Elastomer seals are interchangeable and can be made from a wide variety of materials. The meter valve is intended primarily for "on" or "off," but with a special form of plunger or special collar that can also be used to adjust flow.
