Brief introduction of Shijiazhuang No.1 Valve Factory Co., Ltd.

The company mainly produces more than 450 sets of equipment, including more than 30 sets of large-scale, refined, rare and imported equipment, and has a stainless steel valve processing center; There is the most complete CNC vertical lathe in China valve industry (0.7m ~12.5m); There is a special machining center for machining the shaft holes at both ends of the butterfly valve; There is a fully functional valve laboratory, which can test valve performance such as flow resistance, pressure difference and flow characteristic curve. In August 2008, the company successfully completed the technical relocation and transformation, with an additional investment of 654.38+0.9 billion yuan in the new factory area; The new factory building is 28,000 square meters; Newly purchased equipment includes: 8m CNC vertical lathe, 160 CNC boring and milling machine, 130 CNC boring and milling machine, 6.3m heavy CNC turning and milling machine center, 3.5m CNC turning and milling machine center, 50 CNC lathes, 2 vertical machining centers, 2 8m automatic welding centers, 1 ABB welding robot, Austria. It has American Haibao plasma cutting machine, German messer underwater plasma cutting machine 1 set, 6m× 6m× 4m trolley annealing furnace 1 set, automatic shot blasting machine 1 set, automatic coating equipment 1 set, and a total of large-scale CNC shearing machines, bending machines and winding machines 140. Improve, upgrade and overhaul the original equipment: 12.5m vertical lathe, 5m vertical lathe, 3.5m vertical lathe, boring machine, 9m long axis circular lathe, CNC blanking equipment, stainless steel machining center equipment, etc. /kloc-more than 0/00 sets (sets). The new workshop area, equipment processing accuracy and processing capacity have made a new leap and are in a leading position in the same industry. From material pretreatment, blanking, welding, heat treatment, machining to assembly, advanced and efficient equipment has become a complete set, laying a solid foundation for providing users with high-quality products. Our company is responsible for drafting the following industrial standards for valves in mechanical industry:

1, JB/T690 1-93 industrial standard for closing mirror valves;

2. JB/T8692- 1998 Industry standard for flue butterfly valves;

3.JB/T8691-1998 industry standard for double knife gate valves.

1. Metallurgical valve: used in blast furnace hot blast stove, dust removal, gas pipe network and other systems. It has been supplied to Shougang Jingtang Iron and Steel (Caofeidian), Shougang, Baosteel, WISCO, Angang and Masteel.

2. Nuclear valves: used for ventilation and water treatment systems such as pressurized water reactors, high temperature gas cooled reactors and experimental reactors, and have been supplied to Daya Bay Nuclear Power Station, Qinshan Nuclear Power Station, Tianwan Nuclear Power Station and Pakistan Chashma Nuclear Power Station.

3. Valves for energy saving, emission reduction and environmental protection: used in TRT differential pressure power generation, CCPP, desulfurization, denitrification, sintering waste heat recovery, cement plant waste heat power generation and other systems, and have been supplied to large, medium and small steel companies and cement plants at home and abroad.
