轴承套在两端设置有橡胶密封结构， 以预防固体颗粒如泥沙渗入轴承。
球阀的开关操作是通过一个（或两 个）液压双作用接力器（油缸）驱动一个 （或两个）拐臂旋转实现。拐臂与阀轴通 过键连接。接力器（油缸）锚固于球阀的 混凝土基础中。
液压系统采用压力油罐蓄能或重锤蓄 能，在紧急情况下（即使无动力电源 时），阀门也可以实现开启、关闭或动水 关闭，保证阀后机组设备的安全。
特点与用途 Features and Applications
对于水头高于300m的水电站（或抽水蓄能电站），一般采用液控球阀作为水轮机进水阀，安装在水轮机蜗壳 的进口处，其作用为：
1. 为机组检修提供安全的工作条件； 2. 机组停机时减少机组的漏水量，开机时缩短启动所需要的时间； 3. 防止机组飞逸致使事故扩大；
本产品具有检修密封和工作密封；检修密封位于球阀上游侧，采用手动控制；工作密封位于下游侧，采用自 动控制。 上、下游侧的动密封环沿管道方向移动，与固定在活门上的压环接触形成密封；密封副在开关过程中 无摩擦，从而驱动力矩小，寿命长，安全可靠。
The Hydraulic Controlled Spherical Valve has maintenance seal in upstream and working seal in downstream. Maintenance seal is manual controlled, working seal is automatically controlled. Movable sealing ring of maintenance seal and working seal can be moved along the pipeline direction to form sealing with the fixed ring on the plug. Sealing pairs is friction-free in the operation. The valve has small driving torque, long life-span and best safety and reliability.
The series of Hydraulic controlled Spherical Valve is adopted advanced design theory and methods. We use scientific theoretical calculations and advanced analysis software to ensure that various parameters of product performance accord with project’s requirement, ensure that the product is reliable and safely whatever work conditions.
The Hydraulic Controlled Spherical Valve is usually used in hydropower station（or pump storage power plant）as inlet valve when the net water head is more than 300m. It is installed at inlet of the spiral case of hydraulic turbine. Its main functions include as follows:
自来水
WATER SUPPLY
石化
PETROLEUM AND CHEMICAL
供暖
HEATING
水利
IRRIGATION
钢铁冶金
STEEL AND METALLURGY
普林斯系列产品 — 水轮机进水球阀
Precise Series Product — Turbine Inlet Spherical Valve
球阀密封副采用不锈钢材料，经过精加工成，在不拆卸阀门主体的情况下，即可更换工作密封和检修密封。
The sealing pairs are well machined with stainless steel. The maintenance seal and working seal can be replaced without dismantling main body of valve.
The pressure oil operating system adopts pressure oil storing tank or harmmer. The valve can realize open, closing, closing by dynamic water to ensure safety of set equipments behind valve in case of emergency (even if power supply fails).
The Hydraulic Controlled Spherical Valve has opening position indicator, and inputting and quitting indicators of maintenance seal and working seal.
The valve body is assembled by two parts. It is fabricated with alloy steel casting or steel plate. Two parts are connected by pretension bolts.

阀轴在阀体轴承内转动，轴承为自润 滑复合材料，其承载能力强，自润滑及耐 磨性能好，摩擦系数小。
阀轴与阀体的密封为橡胶，其安装在 阀体外的压盖内。这些密封在不拆卸球阀 的主要部件（阀体和转动部分）和压力钢 管不排水的情况下很容易地被更换。
1. To provide safe working conditions for examination and maintenance. 2. To reduce water leakage during set stopping period and reduce necessary starting time during starting period. 3. To prevent enlargement of accidents caused by the set’s running away.
本系列产品基于先进的设计理念和设 计方法，采用科学的理论计算和先进的分 析软件，确保产品的各参数满足工程的要 求，确保产品在各种工况下使用的可靠性 和安全性。
Valve shaft is assembled in sliding bearing sleeve. The bearing with high load capacity is self-lubricating compounding material and has small friction factor.
阀体为非对称的两部分， 连接面在枢轴的下游侧， 阀轴与活门为螺栓联结。
Valve body is made of asymmetric parts. The connection interface is at the downstream of axes. Valve shafts and plug are connected by bolts.
