The Hubei North Project is a major strategic livelihood project that fundamentally solves the problem of drought and water shortage in the northern part of Hubei. The project takes Danjiangkou Reservoir as the water source, takes water from Qingjianggou of Danjiangkou Reservoir, and crosses the Hubei North Land from northwest to southeast. It passes through Laohekou City, Yinzhou District and Zaoyang City of Shuyang City, and Sui County and Zengdu District of Suizhou City. And the city of Hiroshima, ending in the Wangjiachong Reservoir of Dawu County in Xiaogan City. The liquid control butterfly valve is mainly used for the maintenance of the 3.8-meter water pipeline and the connection of the water flow.
Hubei Hongcheng General Machinery Co., Ltd. was founded on March 18, 1956. It is a high-end large-scale valve manufacturing base in China, a national high-tech enterprise and one of the top 500 Chinese machinery companies. The company specializes in producing all kinds of butterfly valves, ball valves, flow regulating valves, gate valves and check valves, etc., with very reliable quality assurance.
In addition, in the process of equipment manufacturing, the supervisors of the Ruihong Engineering Management Co., Ltd. were supervised by the supervisors. The 10 processes of raw material procurement, material performance re-examination and blanking of the main components of the manufacturer were strictly carried out. Quality control. After the equipment was assembled, the valve body strength was 5 minutes, 1.5 times the nominal pressure and sealing performance for 2 minutes and 1.1 times the nominal pressure test. There was no leakage and no deformation during the pressure test, and the strength and performance met the contract requirements.
The site has a diameter of 3.8 m butterfly valve 1.0 MPa, 1.6 MPa appearance quality, installation connection size, valve body strength and sealing test, valve closing time, indicating angle test, hydraulic system performance test, hydraulic locking device input and exit test, empty The test, the accumulator pressure test, etc. were sampled and tested.
Participants reviewed the butterfly valve design drawings, production organization design, manufacturing process design plan, raw material inspection report, assembly and pressure test, paint quality inspection record, production log and supervision witness sampling, on-site quality control and other related documents.
After discussion, the acceptance team believes that the valve body size, size, appearance and shell strength, sealing performance meet the factory requirements, and agreed to pass the acceptance.
