Problems solved by technology

One of the butterfly valves - the new wafer butterfly valve, in the traditional new wafer butterfly valve, the rubber of the sealing ring itself is used to replace the valve packing to prevent the leakage of the medium. In special use conditions, the medium often flows along the valve stem Outward leakage causes the valve to leak
Cause sealing failure, if it is an electric valve valve, it will cause the electric valve to fail

Abstract

The invention provides a novel butt clamp butterfly valve. The novel butt clamp butterfly valve comprises a valve body, an upper valve rod, a sealing gland and an end cover; the valve base is positioned on the inner side of the valve body; the upper valve rod longitudinally penetrates through the upper part of the valve body, and is fixed at the upper end of the valve base; the lower valve rod is opposite to the upper valve rod; the sealing gland is positioned at the top end of the valve body; and the end cover is positioned at the bottom end of the valve body. A sealing chuck of the novel butt clamp butterfly valve can select a material of combining polytetrafluoroethylene with graphite or glass fibers or carbon steel, so that the sealing chuck is more rigid, resists corrosion, and is wider in application range; and the valve base uses a polytetrafluoroethylene material, so that a torque value is reduced, and the novel butt clamp butterfly valve is lighter and more flexible.

Description

technical field [0001] The invention belongs to the field of valves, and in particular relates to a novel wafer butterfly valve. Background technique [0002] Existing valves are of a great variety and are widely used, and butterfly valves are widely used in industrial pipelines such as water supply and drainage, food, and chemical industry as one of the valves for regulating and throttling. Its working principle is: by rotating the handle, the valve stem is rotated, and then the butterfly plate is driven to rotate to achieve the purpose of opening or closing. One of the butterfly valves - the new wafer butterfly valve, in the traditional new wafer butterfly valve, the rubber of the sealing ring itself is used to replace the valve packing to prevent the leakage of the medium. In special use conditions, the medium often flows along the valve stem Leakage to the outside causes the valve to leak. Lead to sealing failure, if it is an electric valve valve, it will cause the ele...
