In the recommendation activity of "Brand Products" for Shanghai small and medium-sized enterprises organized by Shanghai Small and Medium-sized Enterprises Brand Building Promotion Committee in October 2010, our company's fire valve and smoke exhaust fire valve "Xianlong" were both awarded Shanghai brand products.
The products are widely used in high-rise buildings, modern workshops, nuclear engineering, military ships and ships and other occasions requiring air conditioning.
I. Product name and Features:
Product name is fire valve, exhaust valve series products. This product from the material selection, processing technology advanced and stable performance and other aspects are in the domestic advanced ranks.
The processing of fire valve and smoke exhaust valve series products is completed by AMADA series of punching, shearing, folding, laser and other world-class sheet metal processing equipment computer programming automatically. Factory production lines with the valve body, valve actuator assembly line, physical performance test room, fire valve actuator temperature test chamber, finished products leakage air volume and air valve, fire valve series of products related to production and testing equipment, production lines of each step is through strict barcode scanning transfer in the ERP.
Before the products leave the factory, the factory quality inspection department adopts the air leakage testing device to test and pass the inspection before leaving the factory, and the factory implements the ISO9001 quality management system.
The valve body and blade are made of high quality galvanized steel, which have the advantages of beautiful appearance, good anti-corrosion performance and long service life.
Valve combination with the current international most advanced sheet metal connecting technology - TOX without welds connection technology, so as to solve the combination of galvanized steel without welds between technical issues, TOX no solder connection technique is characterized by: two coin material in the absence of rivets, bolts, solder, using special equipment and mould, put two coin material extrusion force as a body, has the advantages of firm connection, and smooth appearance, the process has been used in automobile manufacturing, the connection strength than riveting and welding process).
The valve body and flange adopt one body common plate structure, which can be connected with the ordinary air duct by bolt, and also can be connected with the mechanical air duct by clasp.
(I) V-shaped anti-slip structure is designed between the blade and the rotating shaft to ensure that the blade will not slip or become loose under high wind speed.
(2) leaf blade rotate bearing and connecting rod bearing adopt oil powder metallurgy copper collar, do not need to refuel, to ensure permanent lubrication, ensure that the valve can even in a long time not to use in the open when rotate freely, changed the traditional process using common copper interplanting leaf blade bearing, and bearing is set on the connecting rod shaft not, over time there will be jammed phenomenon.
(iii) In order to facilitate the commissioning and daily maintenance of users, and in the side of the valve body set up an inspection mouth, used to check the working state of the valve blade. The improvement of this process is far ahead of the products of the same trade.
