Abstract

The invention provides a flange type sluice valve, comprising a valve body, flashboards, flanges, a valve cap and a valve body, wherein valve seats are mounted at the left and right sides inside the valve body, respectively; the wedge-shaped flashboard is mounted in each valve seat; the flanges are assembled at the joints of the two ends of the valve body and a pipeline; the valve body is connected with the valve cap by means of a bolt; the valve rod is mounted at the middle part of the valve cover; the lower end of the valve rod is connected to a valve plate; a valve rod nut is mounted on the upper part of the valve rod; the upper end of the valve rod nut is connected with a handwheel; and a sealing rubber ring is arranged at the joint of the valve body and the flange. The flange type sluice valve has the beneficial effects of light on-off operation, reliable sealing, low fluid resistance, low erosion and corrosion of the sealed surface caused by a medium, simple structure, short structure, good manufacturability and wide application range.

Description

technical field [0001] The invention belongs to the field of valves, in particular to a flanged gate valve. Background technique [0002] Flanged gate valve is a gate valve with flange connection, which is the most common connection method. Flange gate valves are stable and reliable when used in pipelines, so flange gate valves are wrongly used in high-pressure pipelines. For a long time, the general gate valves used in the market have a complicated structure, water leakage or rust are common, the sealing surfaces are easy to cause erosion and scratches, and maintenance is relatively difficult. Contents of the invention [0003] The problem to be solved by the present invention is to provide a flanged gate valve with light switch and reliable sealing. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a flanged gate valve, including a valve body, a gate plate, a flange, a valve cover, and a valve...
