1、 The electric two-way valve ball valve is a Tao product equipped with the fan coil of the central air conditioner
It is composed 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 as to realize the on or off of the cold Shui or hot Shui of the pipe, and then supply air through the fan coil to realize the automatic adjustment of the temperature
The electric two-way valve consists of the temperature sensor TE-1, the proportional integral temperature controller TC-1 and the electric regulating valve TV-1
The air supply temperature control system is installed on TE-1 of the air supply pipe, and the detected temperature Xin is transmitted to TC-1, TC-1 continuously compares the detected value of TE-1 with the set value, and continuously outputs Xin number at the same time, controls the Kai degree connection of TV-1 to be adjustable, and finally keeps the ambient temperature measured by TE-1 within the set temperature range
The air pressure difference Kai closes dps-1 to detect the air permeability of the filter screen
The dirtier the filter screen is, the lower the air permeability is, and the greater the pressure difference on both sides is
When the pressure difference exceeds the set value of dps-1, the micro Kai switch operates and sends out the Jingxin signal
When the temperature behind the coil is lower than a certain limit, the low temperature protection Kai turns off TS-1 and cuts off the power supply of the forced draft fan, so as to close the fresh air valve to prevent the Shui in the coil from freezing and cracking the coil
　1
It is used to control the Kai on or off of cold Shui or hot Shui air conditioning system pipes, so as to control the room temperature
　2
The driver is driven by a single hysteresis synchronous motor, the tan spring of the valve is reset, and the valve is in a normally closed state when it is not working
When it needs to work, the thermostat provides a Kai Kai Xin signal to make the electric valve act by connecting the AC power supply
　3

Kai opens the valve, and the frozen Shui or hot Shui enters the fan coil to provide air conditioning or heating for the room
When the room temperature reaches the set value of the temperature controller, the temperature controller cuts off the electric valve, resets the tan spring to close the valve, so as to cut off the Shui flow into the fan coil
By closing and Kai opening the valve, the room temperature is always maintained within the temperature range set by the temperature controller
　4

The driver of zyft series electric valve is connected with the valve 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, with small space occupation, reliable and durable products, low working noise, and can work reliably in the high temperature and high humidity environment that often occurs in the concealed fan coil unit
The actuator adopts cast aluminum bracket and plastic shell, with small volume and light weight Permanent magnet synchronous motor with hysteresis clutch mechanism is selected, which has reliable self-protection function Suitable for a variety of control Xin numbers: increment (floating point), voltage (0 ~ 10V), current (4 ~ 20mA) It has 0 ~ 10V or 4 ~ 20mafan feed Xin number (optional) The transmission gear adopts metal gear, and dada improves the service life of the driver Low power consumption, output power Da, low noise The valve body can be 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 is convenient for installation, and its structure conforms to IEC international standards; The structure of valve body includes two-way valve (single seat), two-way balance valve (balance type), three-way confluence valve and three-way diverter valve, which are divided into direct acting type and pilot type

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 supply must be cut off before installation, repair and maintenance
2
When changing the valve body or spool, the fluid must be cut off first to completely relieve the pressure before operation
3
If the valve is leaking during use, the valve must be immediately isolated from the system and drained of fluid
4
Choose ordinary drive head, one thermostat can only be equipped with one electric valve, otherwise the manufacturer will not be responsible for all the consequences

5、 Product features: 1
Shi La propeller, driven by PTC heating, operates without noise, with Tan spring reset function
After power failure, the valve is closed, and the position of travel is indicated by Kai degree
The nut connection and installation method is simple, fast, and easy to disassemble
2
The driver has a straight stroke and good interchangeability
Flow error ≤ 5%。 3
Good stability: the flow change of the terminal equipment is not affected by the system pressure and dynamics, and the flow change is not mutual; 4
Energy saving: it saves 6-20% energy compared with the traditional system
5
High efficiency: dada shortens the debugging time, and the system runs with high efficiency
6
Comfort: the temperature control accuracy is higher, which is more comfortable than the traditional flow system
