防爆电动球阀是工业自动化和过程控制的压力线，具有性能稳定，安装方便，可靠，耐用等优点。电动阀结构简单，只由少数几个零件，材料耗用省;体积小，重量轻，体积小，安装尺寸，驱动扭矩，压力调节阀，简单，快捷，只需旋转90°即可快速启动关闭;进一步还具有良好的流量调节和截流密封特性，中大口径，低压力的适用范围，电动球阀是占主要地位的情况的有*性。
Explosion proof electric ball valve is the pressure line of industrial automation and process control. It has the advantages of stable performance, convenient installation, reliability and durability. The electric valve has simple structure and only consists of a few parts, saving material consumption; Small volume, light weight, small volume, installation size, driving torque, pressure regulating valve, simple and fast, just rotate 90 ° to start and close quickly; Furthermore, it also has good flow regulation and closure sealing characteristics, medium and large diameter, low pressure application range, and the availability of electric ball valve is the main situation.
防爆电动球阀是工业自动化控制系统中的重要执行机构。是根据阀瓣的这种移动形式绕阀杆的轴线作旋转运动的阀门。阀座通口的变化是与阀瓣行程成正比例关系。主要用于截断或接通管路中的介质，亦可用于流体的调节与控制，是工业自动化过程控制的一种管道压元件。
Explosion proof electric ball valve is an important actuator in industrial automation control system. It is a valve that rotates around the axis of the valve stem according to the movement form of the valve disc. The change of valve seat opening is in direct proportion to the valve disc stroke. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. It is a kind of pipeline pressure element for industrial automation process control.
典型的故障，阀门，阀杆之间的弹簧和一个安装在驱动器的行为在其门阀门往复敦促大门之一的地位，这可能是封闭的身体，控制流体应用于活塞在干在执行机构克服弹簧力，从而维持在其它位置通常在开，所以作为控制条件下长期维持，当这种结构阀弃置在大深，和身体的压力大大低于周围海面压力下降，弹簧需要足够大，关闭阀门的力量由于身体的压力作用就干不足够移动门其失败的位置。在情况下可能发生。从而减少了执行机构的规模增加了阀门的深评级。
Typical failure of the valve, the spring between the valve stem and one installed in the actuator acts to and fro urge the position of one of the doors in its door. This may be a closed body. The control fluid is applied to the piston in the dry actuator to overcome the spring force, so as to maintain it in other positions. It is usually open, so it is maintained for a long time under control conditions. When this structural valve is abandoned in a large depth, And the pressure of the body is much lower than that of the surrounding sea surface. The spring needs to be large enough. The force to close the valve cannot move the door to its failed position due to the pressure of the body. Under possible circumstances. This reduces the size of the actuator and increases the deep rating of the valve.
防爆电动球阀阀体可以是整体的，也可以是组合式的，安装维护只需做到以下几点：
The valve body of explosion-proof electric ball valve can be integral or combined. The installation and maintenance only need to do the following:
一、只有卸除球阀前后的压力，才能对球阀进行拆卸操作。
1、 Only after removing the pressure before and after the ball valve can the ball valve be disassembled.
二、球阀阀体重新装配时螺栓一定是对称、逐步、均匀的拧紧。
2、 When reassembling the ball valve body, the bolts must be tightened symmetrically, step by step and evenly.
三、清洗剂与球阀中的橡胶件、塑料件、金属件及工作介质(例如燃气)等均相容。工作介质为燃气时可用(GB484-89)清洗金属零件。非金属零件用纯净水或酒精清洗。
3、 The cleaning agent is compatible with rubber parts, plastic parts, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, metal parts can be cleaned with (gb484-89). Clean non-metallic parts with purified water or alcohol.
四、下来的单个零件可以用浸洗方式清洗。清洗时须去除一切粘附在壁面上的油脂、污垢、灰尘等。
4、 The individual parts can be washed by immersion. All grease, dirt and dust adhered to the wall must be removed during cleaning.
如果还留有未下来的非金属件可采用干净的绸布擦洗，防爆电动球阀可配行程限位开关、电磁阀、减压阀及0.4-0.7MPa气源可实现开关操作，并送出二对无源触点信号指示阀门的开关，适合于介质是粘稠、含颗粒、纤维性质的场合，广泛应用于石油、化工、教学设备、轻工、高压设备、制药、造纸等工业自动控制系统中，作远距离集中控制或就地控制。
If there are still non-metallic parts left, they can be scrubbed with clean silk cloth. The explosion-proof electric ball valve can be equipped with travel limit switch, solenoid valve, pressure reducing valve and 0.4-0.7mpa air source to realize switching operation, and send two pairs of passive contact signals to indicate the switching of the valve. It is suitable for occasions where the medium is viscous, containing particles and fiber. It is widely used in petroleum, chemical industry, teaching equipment, light industry, high-voltage equipment, pharmacy In the automatic control system of papermaking and other industries, it is used for remote centralized control or local control.
