A new type of "three-proof" electronic speedometer sensor was successfully developed by Hangzhou Yongfu Electronic Instrument Co., Ltd.
This new electronic speedometer sensor with waterproof, anti-voltage breakdown and interference and anti-jamming uses a waterproof structure in which electronic components are completely isolated from the shaft magnet. The electronic components are individually enclosed in a sealed cavity. The special waterproof material is used to prevent the electronic components from being burnt due to water seepage during long-term use. At the same time, the product adopts a unique circuit design, with over-voltage protection, reverse power supply protection, input and output voltage regulation, and clutter absorption. It avoids circuit damage caused by excessive voltage or incorrect connection, and makes the instrument indication more accurate. With a unique mechanical design, the shaft connected to the transmission can be telescopic and rocked, making the product more flexible and not stuck during use.
At present, the product has passed the test of the National Automobile Quality Supervision and Inspection Center. The test results are in full compliance with the technical standards of China's automotive industry, QC/T727-2004. The service life of the product can reach more than 500,000 kilometers.

Valves
Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.
People in developed nations use valves in their daily lives, including plumbing valves, such as taps for tap water, gas control valves on cookers, small valves fitted to washing machines and dishwashers, safety devices fitted to hot water systems, and poppet valves in car engines.
In nature there are valves, for example one-way valves in veins controlling the blood circulation, and heart valves controlling the flow of blood in the chambers of the heart and maintaining the correct pumping action.
Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or boilers.
More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
