Abstract

The invention discloses a paper pulp sending control valve which solves the problem that bubbles are prone to occurring in the existing paper pulp sending process. The paper pulp sending control valve comprises two valve bodies which are connected together side by side and are of the same structure, a spherical inner cavity is formed in each valve body and communicated with a paper pulp conveying pipeline, an opening is formed in the bottom of each spherical inner cavity, each opening is provided with a valve element which can open or close the opening, the top of each spherical inner cavity is provided with a gas storage cylinder communicated with the spherical inner cavity, a gas outlet is formed in the top of each gas storage cylinder, and a plug cock is arranged at each gas outlet.

Description

technical field [0001] The invention relates to papermaking technology, in particular to a pulp feeding control valve. Background technique [0002] Modern life is inseparable from paper. The papermaking process is roughly divided into two processes: pulping and papermaking. Pulping is to chop raw materials (trees and grasses, etc.) and cook them in a pot. The cooked pulp is processed by special equipment to process the fibers in the pulp. The processed pulp needs to be screened, bleached and washed. Before papermaking, the pulp needs to be screened to remove slag again. The pulp after slag removal needs to be diluted, and then the pulp is sprayed with a net. After spraying the net, it forms a wet paper. The final paper can be packaged and put into storage. [0003] In the above pulping process, when the pulp is transported to special equipment for fiber treatment, a special control valve is required to control the pulp feeding speed. However, in the existing control val...
