The engineering machinery industry has bottomed out and is waiting for recovery.Recent economic data shows that the net financing of the corporate sector continues to increase year-on-year, indicating that the momentum of manufacturing capacity expansion is still strong.Looking forward to 2024, the implementation and increase of economic stimulus policies will become the main line of the rebound of the construction machinery industry. Special debt issuance is expected to support the growth of infrastructure investment, stimulate demand and supply recovery, and accelerate the recovery of corporate profits.The industry`s overseas exports continue to have bright spots.Affected by the technological upgrading of domestic products, the reintegration of the global industrial chain, and the Russia-Ukraine conflict, overseas exports in many segments of the machinery industry have continued to grow rapidly.The export share of construction machinery and other industries has continued to increase significantly in recent year.

!Gate valve refers to a gate-shaped valve used to cut off and regulate flow. It is installed on the outlet pipeline of centrifugal pumps and mixed flow pumps.The nominal pressure of the gate valve is PN0.1~32; the nominal diameter is DN15~1800; the operating temperature t≤550℃.It has the characteristics of small fluid resistance and small opening and closing torque, and is divided into rigid gate valve and elastic gate valve.Its function is to close the valve before starting the water pump, and use the vacuum pump to pump air and fill it with water; closing the valve when the centrifugal pump starts can reduce the power of the power machine.It is used to connect and cut off the medium in the pipeline.The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, but cannot be adjusted or throttled.The gate valve is sealed through the contact between the valve seat and the gate plate. Usually the sealing surface is surfacing with me.http://baidu.com
