Ill with butterfly valve points, double valve type and most type three, according to the three main forms of valve diameter points, the purpose is to prevent the media back in time to stop the flow or weakened hydraulic shock. 2, stainless steel flange check valve slide along the vertical centerline of the valve body, threaded valve can be installed in horizontal pipelines, small-diameter high-pressure check valve can be used on the ball . The butterfly valve as the valve body shape of the shut-off valve (shut-off valve can be common with), so it is fluid drag coefficient. Its structure is similar to the cut-off valve, and the valve body with the same cut-off valve. Valve and valve cover the lower part of the upper guide sleeve is formed with Jane, Jane valve guide freely in the valve lift light guide, Jane, when the medium downstream, thrust open the valve by the media, when the media stops the flow, the valve by self vertical landing on the seat, to prevent the media from the backflow effect. Butterfly valve straight-through media channels and export channel direction perpendicular to the direction of the seat; the same vertical lift check valve, the direction of media and export channel seat-channel direction, the flow resistance is smaller than the straight-through. 3, stainless steel flange valve: valve rotation about the pins inside the valve seat. Simple disc check valve structure, can only be installed on a horizontal pipe, sealing well. 4, stainless steel flange valve: valve slide along the centerline of the valve body. Pipeline valve is a valve emerging, its small size, light weight, good processing is one of the check valve development. But the fluid drag coefficient is slightly larger than the swing check valve. 5, compression-type check valve: This valve is used as boiler feed water and steam off valve, which has lift check valve and globe valve or angle valve integrated function. In addition, there are - some do not apply to the pump outlet check valve installation, such as a foot valve, spring-type, Y-type and other valve. 3, stainless steel flanges [check] works - Riverstone valve The valve in use, the media flow direction of the arrow. 1, when the media required flow direction, the role of the valve under medium power, is open; when the upstream medium, because the weight of the valve and the valve by the media backward force, the valve and valve seat sealing surface density closed together, to prevent the media countercurrent purposes. 2, the sealing surface of the valve body and stainless steel welding. 3. The length of the structure of the valve according to [1] provides that the provisions of flange dimensions according to ANSI B16.5 for. One, ① stainless steel flange valve product name and model ② ③ caliber stainless steel flange valve flange valve with an attachment so we can correct for your selection.
