Welcome friends from all walks of life to visit, guide and negotiate business. Tonghua ductile iron valve price Jiangsu Tianhuan Machinery Equipment Co., Ltd. Contact: Manager Tel: Address: Zhenwu Industrial Park, Jiangdu District, Yangzhou City, Jiangsu Province Cast iron inlaid copper gate structure: Our company produces various specifications of cast iron gates, cast iron gate is Made of gray cast iron (or ductile iron) as the main material, it has the advantages of corrosion resistance, good water-stopping effect, simple installation, long service life, etc.; cast iron gate water stop has one-way stop water cast iron gate, two-way water stop cast iron gate Form to meet the needs of different working conditions. The water stop adopts precision-processed bronze hard water seal to reduce friction. Wear-resistant and good sealing effect. The structure consists of cast iron square gates, cast iron round gates, two-way water-side square gates, and two-way water-blocking round gates. The opening and closing modes are divided into manual gates. Cast iron inlaid copper square gates. Selection instructions: 1.When selecting the gate, the H value should be indicated. (The center of the gate to the platform of the hoist at the bottom of the hoist); 2. The hoist should be determined according to the opening and closing force and the degree of automation in the table. Specific reference can be made to the hoist sample. 3, platform design load should be considered both positive and negative bearing (closing force reference opening force). 4. The shaft guide is set according to the different depths of the shaft. It should not interfere with the coupling when designing; 5. The whole screw, coupling and gate are made to move up and down as the open lever gate when working. The work is the screw Do not move, move down the gate called the dark rod gate. 6. Directional pressure gate should be selected when it should be used. If the forward pressure gate is used for water pressure according to T8734763674 (not contact method), the head should be <2.5m; 7. The dark gate should be installed in the landscape. In the pit in the middle of a district or a road, this type of gate has its own opening device and does not require a dedicated hoist; 8. When ordering, indicate H, and specify the specific name and model of the individual gate (with the supporting hoist). Specifications; 9, the factory can make other materials (stainless steel, carbon steel, aluminum alloy, plastic) or special shape gate; 10, the factory does not contain any pre-installed parts. 11. Samples provided by the factory are subject to change without notice. Fifth, the use of cast iron gates: Cast iron inlaid copper gates, also known as cast iron gates, mainly used for water supply and drainage, flood control, irrigation, water conservancy, hydropower projects, used to cut off, dredge flow or adjust the role of water level, according to the General Standards of the Ministry of Construction And the United States AWWA standard design and production. It adopts a unique external arc design with reasonable structure and uniform force. It is made of high-quality gray cast iron or ductile iron, made of stainless steel, and seals the surface with copper strips or rubber. After precision machining, it is equipped with grinding to achieve flat contact sealing. The sealing performance is good. When the seal water stopping performance decreases, it can be solved through the adjustment of the wedge device. Shut-off and automatic gate hoists. [Original content] Purify, until all the ditch grid grill dirt is cleared, the water level difference before and after the door is normal until. Before electrical equipment, all electrical connections should be carefully checked and the requirements of the drawings should be met. The insulation resistance of the entire circuit must be greater than the power test before the Ω start. In the hospital. Welding process evaluation: According to the technical requirements and technological requirements of the design drawings, the company has a complete low-alloy steel 16Mn (Q345B) manual arc welding process evaluation, if the gate material changes or welding material requirements change, we will follow T8924398445 measuring tools and construction Equipment inspection and inspection: Prepare the "Water Conservancy and Hydropower Project Construction Quality Evaluation Form" and installation inspection records, make the construction process to record raw data in a timely manner, fill in the "unit project quality assessment form", and pay the supervision engineer to review. Material and safety, calculated the weight of each target, the degree of membership between the target and the level of judgment. A multi-level multi-factor assessment target system was proposed. Establish safety assessment models for gates and cranes. Steel gates are tough and easy to replace. Before the installation, the temperature rise of the motor and electrical components should not exceed their permissible value. The electrical equipment of the motor should be used in the test. During the test, if the contacts and other parts are burned, find out the reason and replace it. No-load hoist test, the entire trip to the next time. Under the top. Check whether the surface of the main frame and the horizontal frame connected to the water is misaligned. If the misalignment is loose, the connecting bolts will stop adjusting the water surface on the same plane. When the concrete is poured, flow to the door, gantry, oblique iron, the gap in the mortar baffle should be cleared, purify, until all the ditch grid mesh dirt cleared, the water level before and after the door is normal until the difference. Before electrical equipment, all electrical connections should be carefully checked and the requirements of the drawings should be met. The insulation resistance of the entire circuit must be greater than the power test before the Ω start. After purifying, until all the gutter grids are cleared of dirt, the water level difference between the door and the door is normal until. Before electrical equipment, all electrical connections should be carefully checked and the requirements of the drawings should be met. The insulation resistance of the entire circuit must be greater than the power test before the Ω start. in
