兴淼液压升降直板坝 弧形坝闸门特点:

1,原理独特，作用微妙，结构简单，使用方便，运行平稳。
2，施工简便，造价合理，投资小，功能全。
3，自动启闭，自控水位准确，运行平稳安全，稳定性良好。
4,维修方便，使用寿命长，费用低。
5，上游水位稳定 ，关闭后水库水位即与门顶齐平，在运转设计有效范围内，*运转水位不大于门高的10-20%
6，由于能准确自动调节水位，就当前资源短缺，在合理使用和利用水资源有其独到之处。

.3.3.5 hydraulic cylinder
The hydraulic cylinder is connected with the foundation embedded plate in the first-stage concrete through the support hinge. The piston rod lifting head is connected with the bottom shaft of the flap gate by the lifting shaft through the crank arm.
The hydraulic cylinder body, piston and piston rod must be delivered in a complete set. The ceramic piston rod can be subcontracted for processing by the contractor. However, the subcontractor shall obtain the approval and written approval of the employer, supervisor and engineering design unit in advance.
The assembled cylinder assembly shall have hooks or devices for installation and transportation.
The design of the hydraulic cylinder must meet or exceed the service characteristics specified in this technical specification or SL41 (water
The provisions of the design specification of electric hydraulic engineering hoist and shutter. The hydraulic cylinder is designed with single piston rod type, double action and heavy load. The hydraulic cylinder is provided with a lifting head (with self-lubricating joint bearing) and a connecting pin shaft at the overhanging end of the piston rod, and its size and type match with the lifting lug of the gate. The manufacture of hydraulic cylinders must comply with DL/T5019 (code for construction, installation and acceptance of opening and closing mechanisms for water conservancy and hydropower projects).
1, the hydraulic cylinder cylinder body should be priority to use the whole section of seamless steel pipe production, material should meet or equivalent
The mechanical properties of no. 45 steel of GB/T699 or 0345B of GB/T1521 shall meet the requirements of the specification after hot treatment specified in GB/T699 or GB/T1591. When sectional welding is adopted, the welding parts of the cylinder body shall be treated by tempering and tempering, and the welding dimension shall be qualified by ultrasonic inspection and appearance inspection of 100% weld length according to the requirements of the first level welding seam, and conform to JB1151 (ultrasonic inspection regulations on high-pressure seamless steel tube). Where welding is used, weld inspection data should be provided, according to the ANSIB46.1 hydraulic cylinder inner diameter surface processing recommended to use question I, the coarse flame must reach more than 0.4ym
