1、 The electric two-way valve ball valve is a tao product for the fan coil unit of the central air conditioner, which consists of a driver and a valve body. The driver is driven by a synchronous motor, and has the functions of tan spring reset and manual kai valve lever operation.
2、 The valve body adopts piston structure. The electric valve can be used with the temperature controller. The temperature controller controls the motor of the electric valve to make the valve kai or close, so that the cold or hot shui of the pipeline can be connected or disconnected. Then, the air is supplied through the fan coil to achieve automatic temperature regulation. The electric two-way valve consists of a temperature sensor TE-1, a proportional integral temperature controller TC-1 and an electric control valve TV-1, which are installed in the TE-1 of the air supply pipeline, Transmit the detected temperature xin number to TC-1, and TC-1 will continuously compare the detected value of TE-1 with the set value. At the same time, it will continuously output xin number, and control the Kai degree connection of TV-1 to be adjustable. Zui will finally keep the ambient temperature measured by TE-1 within the set temperature range. The air pressure difference Kai turns off DPS-1 to detect the air permeability of the filter screen. The dirtier the filter screen, the more di the air permeability, and the more da the pressure difference on both sides. When the pressure difference exceeds the set value of DPS-1, inching Kai closes the operation and sends an alarm Jingxin number. When the temperature di behind the coil is at a certain limit, the di temperature protection kai turns off the TS-1 to cut off the power supply of the forced draft fan, so that the fresh air valve is closed, preventing the shui in the coil from icing and cracking the coil. 1. It is used to control the opening or closing of Kai of cold or hot shui air conditioning system pipes to control the room temperature. 2. The driver is driven by a single hysteresis synchronous motor, the valve tan spring resets, and the valve is normally closed when it does not work. When it needs to work, the thermostat will provide a Kai Kai Xin number to connect the electric valve to the AC power supply and act. Kai opens the valve, and the frozen or hot shui enters the fan coil to provide cooling or heating for the room. When the room temperature reaches the set value of the temperature controller, the temperature controller will power off the electric valve, reset the tan spring to close the valve, so as to cut off the shui flow into the fan coil, and keep the room temperature within the temperature range set by the temperature controller through valve closing and Kai opening. The driver and valve of ZYFT series electric valve are connected by thread. The driver can be installed after the valve is installed. Field assembly, flexible and convenient wiring. The plane design of the driver can be installed close to the wall, occupying small space, reliable and durable products, working noise di, and can work reliably in the high temperature and humidity environment that often occurs in the concealed fan coil unit. The actuator is made of cast aluminum bracket and plastic shell, small in size and light in weight. It is made of permanent magnet synchronous motor with hysteresis clutch mechanism, which has reliable self-protection function. It is suitable for multiple control xin numbers: increment (floating point), voltage (0~10V), current (4~20mA). It is made of 0~10V or 4~20mAfan feed xin numbers (optional). The transmission gear is made of metal gear, Dada improves the service life of the actuator. The power consumption di, output force da, and noise are low. The valve body is made of cast copper, cast iron, cast steel, and stainless steel to meet the requirements of different working media and temperatures. The valve body has two types of threaded connection and flange connection, which are easy to install, and its structure complies with IEC international standards; The valve body structure includes two-way valve (single seat), two-way balance valve (balanced type), three-way confluence valve and three-way diverter valve, which are divided into two types: direct acting and pilot operated.
3、 Maintenance: 1. If the valve is leaking, drain the fluid or isolate it from the system. 2. Check whether the valve element assembly needs to be replaced. 3. If the drive does not work or moves up and down continuously, replace the whole drive.
4、 Precautions: 1. The power must be cut off before installation, repair and maintenance. 2. When replacing the valve body or valve core, the exhaust valve of the fluid da kai air disc must be cut off to completely relieve the pressure before operation. 3. If the valve is leaking during use, the valve must be isolated from the system immediately and the fluid must be discharged. 4. If ordinary driving head is selected, one temperature controller can only be equipped with one electric valve, otherwise, the manufacturer will not be responsible for all consequences.
5、 Product characteristics: 1. The shi wax propeller is heated and driven by PTC. It runs noiseless, with tan spring reset function. After power failure, the valve is closed, and the stroke position is indicated by Kai degrees. The nut connection and installation method is simple, fast, and easy to disassemble. 2. The driver is straight stroke with good interchangeability. Flow error ≤ 5%. 3. Good stability: the flow change of the end equipment is not affected by the system pressure and motion, and the flow changes are not mutually; 4. Energy saving: It can save 6-20% energy compared with the traditional system. 5. High efficiency: Dada shortens the debugging time, and the system runs with high efficiency. 6. Comfortable: higher temperature control accuracy, more comfortable than traditional flow system.
