Abstract
The utility model discloses a pneumatic flow control valve, which comprises flanges, a valve body, a spool, spool shafts, air permeable cloth, a crank and a cylinder. The flanges are mounted at both the upper part and the lower part of the valve body, the spool is mounted inside the valve body and is connected and fixed through the two spool shafts, the air permeable cloth is mounted on one side of the spool, and the cylinder is connected with the exterior part of the valve body and is connected with the spool shafts through the crank. The O-shaped straight-through design of the utility model can prolong the service life of product.
Description
Technical field
The utility model relates to a kind of device of control flow rate, is specifically related to the pneumatic flowrate control valve in a kind of powdery flow control system.
Background technique
Along with the continuous development of mechanical industry, various exquisitenessization joint parts are also constantly aspiring after perfection, and the pneumatic flowrate control valve is exactly under such condition, and are further perfect.
The spool of at present domestic pneumatic flowrate control valve all adopts the mode of structure of U type notch basically.
Summary of the invention
The purpose of this utility model is for a kind of pneumatic flowrate control valve of full-automatic, high sealing is provided, and can reduce leaking of dust when unloading ash.
The technical solution of the utility model: a kind of pneumatic flowrate control valve, comprise flange, valve body, spool, poppet shaft, ventilative cloth, crank and cylinder, a flange is respectively installed in described valve body upper and lower part, valve inner is installed a spool, and be connected and fixed by two poppet shaft, ventilative cloth is installed on one side of spool, and described valve body is externally connected to cylinder, and cylinder is connected with described poppet shaft by crank.
Start cylinder during use, drive poppet shaft by crank, thus rotational valve core.
The beneficial effects of the utility model are: the pneumatic flowrate control valve is as the effect switch in the powdery flow control system, its basic existence is exactly in order to prevent the leakage of travel fatigue, but the design of U type groove, can only say and to play a role at the beginning, time is impermanent, and O type straight-through type design of the present utility model can increase the working life of product.
