进口气动高真空球阀 德国洛克LOCKE

一、进口气动高真空球阀产品概述：

德国《LOCKE》洛克--进口气动高真空球阀是应用在真空系统中（又能适应一定的压力下）开启或切断气流的高真空球阀。阀门由回转气缸和阀体组成通过电磁换向阀改变气路方向，来驱动球阀启闭。本阀门外形结构紧凑，美观，密封座补偿式设计。有自动补偿密封座磨损功能，密封可靠，寿命长等优点。阀门气缸可选择单作用和双作用结构，可选配信号反馈控制，防爆电器装置及气源处理元件。适用的工作介质为带酸、碱性的各类气体或液体。

进口气动高真空球阀产品特点：

1、密封结构设计du特漏率可达到＜1×10-10Pa.M3/S,改变了球阀不能满足高真空、超高真空的现状；

2、开关扭矩小,配置气动执行器小，工作稳定，可靠；

3、结构紧凑,重量轻,外形简洁、美观；

4、气动高真空球阀既能适用高真空又能适用一定的正压力下使用由于球阀全通导又能达到超高真空要求,所以气动真空球阀也能适用于加速真空系统。

进口气动高真空球阀工作原理：

a、当气动执行器与电路和系统气源接通后，空气通过管道A或B管进入A缸（B缸）推动b、活塞向一端运动，从而带动旋转轴和球芯转动90°

c、气动执行器ding部连动可视器，当绿色标志指向“开”字时标志阀门开启。

d、回信器信号灯绿灯亮时阀门处在开启位置，而红灯亮时阀门处在关闭位置

e、气动高真空球阀定位器可调节阀门管道流量

Introduction of imported pneumatic high vacuum ball valve products:

Locke imported pneumatic high vacuum valve is composed of double (single) action pneumatic piston actuator and imported Locke high pressure ball valve. Pneumatic high vacuum ball valve is a new type of valve with automatic control and remote control. It is widely used in gas station, tanker and other high-pressure pipeline, and its connection form is divided into internal thread (g / NPT), welding, ferrule and so on. The pneumatic piston actuator is made of low friction material, and the inner and outer surfaces of the cylinder block are treated by hard anodizing, which greatly improves the service life of the cylinder.

Features of imported pneumatic high vacuum ball valve:

1. The Du leakage rate of sealing structure design can be less than 1 × 10-10pa.m3/s, which changes the current situation that the ball valve can not meet the requirements of high vacuum and ultra-high vacuum;

2. Small switch torque, small pneumatic actuator, stable and reliable operation;

3. Compact structure, light weight, simple and beautiful appearance;

4. Pneumatic high vacuum ball valve can be used in both high vacuum and positive pressure. Because the ball valve is fully conductive and can meet the requirements of ultra-high vacuum, pneumatic high vacuum ball valve can also be used in accelerator vacuum system.

Working principle of imported pneumatic high vacuum ball valve:

a. When the pneumatic actuator is connected with the circuit and system air source, the air enters cylinder a (cylinder b) through pipe a or pipe B to push piston B and piston B to one end, thus driving the rotating shaft and ball core to rotate 90 degrees

c. When the green mark points to "on", the valve is opened.

d. When the green light is on, the valve is in the open position, while when the red light is on, the valve is in the closed position

e. Pneumatic high vacuum ball valve positioner can adjust valve pipeline flow

Performance range of imported pneumatic high vacuum ball valve:

1. Valve leakage rate: ≤ 1.3 × 10-4Pa.L/S.

2. Dimensions: dimensions DN 15-dn 200

3. Applicable temperature: applicable temperature - 30 ～ + 150 ℃ (PPL seal)

4. Gas source pressure: annoy pressure 0.4 ～ 0.6MPa

5. Scope of application: applicability

6. Connection type loose flange service pressure range (PA)

7. Looper flange (gb6070) 0.6 × 106～1.3 × 10-4

8. Welding flange (gb6070) 1.6 × 106～1.3 × 10-4

9. Quick release flange (gb4982) 0.1 × 106～1.3 × 10-4

10. Threaded connection 1.6 × 106～1.3 × 10-4
