July 3 (Sony): "I believe that under the strong support of the national industrial policy for manufacturing, the strong support of Guilin Municipal Party Committee, the municipal government, various government departments, brothers, and the people of Guilin, Yuchai and Guilin Fu Delta's strategic cooperation will surely be promoted with a brand new look and faster pace. It will make due contributions to accelerating the development of both sides and promoting the growth of the local industrial economy!" June 29th, Guangxi Yuchai Machinery Group and Guilin Fu At the signing ceremony of the "Strategic Cooperation Agreement" signed by Delta Group Co., Ltd., Yu Ping, chairman of the board of directors of Yuchai Group, sincerely hopes. Gu Tangsheng, President of Yuchai Group Co., Ltd. and Li Fuchao, Chairman of Guilin Fuda Group Co., Ltd. solemnly signed the agreement.
Yuchai Group is China's largest internal combustion engine production base and the world's largest independent diesel engine production base. The Guilin Fuda Group is an enterprise group that produces and sells automotive engine parts such as engine crankshafts, clutches and gears, and low-speed automobiles. It is a leading company of clutches in China. Guilin Fuda and Yuchai have a long-term cooperation relationship of more than 20 years. With good supply capacity, Guilin Fu reached a trustworthy partner for Yuchai.
The strategic cooperation with Guilin Fuda is an important step in the strategic layout of Yuchai, and it is also an important part of the company's efforts to achieve resource reorganization. The formation of strategic cooperation will enable the two sides to achieve mutual complementarity in industry, technology, talent, and management, and will be a strong combination of mutual promotion and common development. This will open a new chapter in bilateral cooperation.
Yu Ping said: "Yuchai will take this cooperation as a new starting point, continuously deepen cooperation with Guilin Fuda, steadily expand product variety and supporting share, and make full use of its own technology and human resources to help in the entire system of the group. Guilin Fuda will carry out technological transformation and technological development; at the same time, Yuchai will actively coordinate the Yuchai suppliers to invest in Guilin, which will prolong and enrich the manufacturing industry chain of Guilin, and will play an important role in revitalizing the manufacturing industry of Guilin and promoting the development of the local economy. The role of promotion!"
Li Fuchao said that this cooperation will promote Fuda’s efforts to keep pace with Yuchai’s development and quickly expand and strengthen the company, so that the Fuda Group is more confident to achieve a 10 billion Fuda “12th Five-Year†development plan. .
Guilin Mayor Li Zhigang, Deputy Mayor Wu Jiashi, and Municipal Government Secretary Zhang Xiaowu witnessed the signing ceremony between Yuchai Group and Guilin Fuda. Su Peng, vice president of Yuchai Group Co., Ltd., and Li Gang, deputy general manager of Party Committee of Guilin Fuda Group Co., Ltd. attended the signing ceremony.
Wu Jiashi, on behalf of the Guilin Municipal Government, congratulated the two parties on their successful signing and cooperation. He said that Guilin will strongly support the sincere cooperation between Yuchai and Fuda. It is believed that the strategic cooperation between the two sides will be promoted with a brand new look and faster pace. It will be necessary to speed up the development of both sides and promote the growth of local industrial economy. Contributions.

Gate Valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. For extremely thick fluids, a specialty valve often known as a knife valve is used to cut through the liquid.[1] On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that flow rate does not change evenly with stem travel. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be fully opened or closed.[2] When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.[3]
Gate valves are characterised as having either a rising or a non rising stem. Rising stems provide a visual indication of valve position because the stem is attached to the gate such that the gate and stem rise and lower together as the valve is operated. Non rising stem valves may have a pointer threaded onto the upper end of the stem to indicate valve position, since the gate travels up or down the stem on the threads without raising or lowering the stem. Non rising stems are used underground or where vertical space is limited.
Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.
Another type of bonnet construction in a gate valve is pressure seal bonnet. This construction is adopted for valves for high pressure service, typically in excess of 2250 psi (15 MPa). The unique feature about the pressure seal bonnet is that the body - bonnet joints seals improves as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-bonnet joint.
Gate valves may have flanged ends which are drilled according to pipeline compatible flange dimensional standards. Gate valves are typically constructed from cast iron, ductile iron, cast carbon steel, gun metal, stainless steel, alloy steels, and forged steels.
All-metal gate valves are typically used in ultra-high vacuum chambers to isolate regions of the chamber
