Electric valve is a device that drives the valve to open and close by electric motor. It is widely used in various industrial and civil fields, such as metallurgy, chemical industry, petroleum, natural gas, heating, ventilation and air conditioning, automatic control, etc. The following are some application scenarios of electric valves:
1. Fluid control in industrial production: electric valve can be used to control the flow, pressure and temperature of liquid, gas and steam to meet the needs of industrial production.
2. Oil and natural gas industry: electric valves can be used in oil and natural gas exploitation, processing, transmission and storage to control flow and pressure and ensure production safety and efficiency.
3. Chemical industry: electric valve can be used for fluid control in chemical production, such as acid-base solution, gas and liquid reactant control, to ensure the safety and efficiency of production.
4. Heating, ventilation and air conditioning system: the electric valve can be used to control the water flow, air flow and temperature in the heating, ventilation and air conditioning system to meet the requirements of the indoor environment.
5. Automatic control system: electric valve can be used with automatic control system to realize automatic control and adjustment of fluid flow, pressure, temperature and other parameters.
In short, electric valves are widely used in industrial and civil fields, which can improve production efficiency, ensure product quality and improve production safety.

3G wireless video surveillance not only provides a way to access via the Internet, but also provides a more creative way of monitoring 3G video phone channels. This way, if you use an ordinary 3G mobile phone, you don't need to install software. Just dial a video call and the camera's real-time monitoring video will immediately appear in front of you, making monitoring very simple. The biggest advantage of 3GCamera is that the user is always on the line. Once there is alarm, the camera will automatically call back the set 3G mobile number. Just press an answer button and the video will be in full view in any situation. Using the audio channel of the video phone, the 3G version of hand-to-eye communication can also realize on-site monitoring and intercom functions, making it easier for you to understand the situation at the monitoring site and shouting to oust the thieves.
In addition, 3G hand-eye camera can be controlled by mobile phone z around 360 ° / up and down 90 ° rotating camera, four zoom control, remote control video, mobile video recording browsing, mobile phone arming and disarming, mobile number filtering, access password protection, external sensors (infrared probe, magnetic door, smoke, gas, and shooting) and other functions, so that the 3G version of hand-eye through the core of home security.
Through 3G Internet access, 3G version of the hand-eye can access the Internet, support remote Web access through the DDNS, Internet monitoring, and use H.264 video encoding. Can be connected to the platform to focus collective management. Through the 3G video phone channel transmission monitoring images, high security, stable 64Kbps transmission channel, the image is clear and smooth.
For any 3G mobile phone, there is no need to install software. Users only need to dial one phone for ease of use.
As long as the 3G SIM card is purchased from the sales office, it can be used without any ISP and end-to-end video transmission. Privacy is guaranteed.
3G wireless video surveillance is a simple and easy-to-use small-scale remote wireless monitoring system. It adopts the latest 3G communication technology and targets the needs of home, small-scale enterprises or users in certain industries. It is designed to achieve a simple installation and flexible operation. Cost-effective 3G mobile video surveillance equipment.
