Automatic flow regulating valve for grate cooler

Abstract

The invention relates to an automatic flow regulating valve for a grate cooler. The automatic flow regulating valve is characterized by comprising a valve body, a valve plate, a bottom air plate and a valve plate bob-weight, wherein the valve body and the bottom air plate are connected into a whole through welding; the valve plate and the valve plate bob-weight are connected through welding; a hook rail is arranged in the valve body, the hook rail is used for hanging the valve plate on the valve body; the top of the valve body is provided with a bolt hole; and the valve body and the wallboardof the grate cooler are connected and hung on the valve plate by a bolt. The automatic flow regulating valve provided by the invention has the following advantages: (1) because the bottom air plate is an arc open hole, the problems that the grate cooler material bed waves and an air supply system automatically balances are solved; (2) the bottom air plate and the valve body are connected into a whole so as to simplify the structure; and (3) the valve plate is thin and is only 12mm, the weight is concentrated on a hybridization block, the gross weight is lighter, and the manufacturing cost is reduced.

Description

technical field [0001] The invention proposes an automatic flow regulating valve for the cooling air supply of the grate cooler, which is an air volume and flow regulating valve with no power drive, gravity adjustment, automatic compensation, and automatic adaptation to system balance, which can meet the air supply requirements of the grate cooler. System technological progress requirements. Background technique [0002] Existing technology such as F.L.Smidth's regulating valve, its structure is that the air plate at the bottom is composed of small holes, the bottom air plate is connected to the valve plate, the valve plate is very thick, because the bottom air plate is composed of a If it is composed of a small hole, it cannot solve the problem of the fluctuation of the material layer of the grate cooler and the automatic balance of the air supply system. The bottom air plate is connected to the valve plate, and the very thick valve plate makes the structure appear complic...
