The principle of electric two-way valve and installation: 1. Electric two-way Industrial Valves used to control the cold water or hot water air conditioning system of the pipe open or closed, to achieve the purpose of the control room temperature. 2. Single-phase hysteresis synchronous motor drive, drive by the valve spring reset, the valve does not work in a normally closed state, when the need to work, provided by a thermostat open signal to make the electric two-way valve connected to the ac power and action. 3. Open valve, chilled water or hot water into the fan coil units, to provide room air conditioning or heating, when the room temperature reaches the thermostat set point, the thermostat to power electric two-way valve, reset spring to close the valve, thus cutting into water fan coil units, through the valve closed and open, make the room temperature always stay in the temperature control setting temperature range. 4. VA7010 series electric two-way valve drive and valve adopts threaded connection method, can be in after installation of valve, and then install the drive. Field assembly and connection flexibly and conveniently. Drive the plane design can be installed close to the wall, to take up the space is little, products are reliable and durable, low operating noise, and can appear in the concealment type fan coil units of high temperature and high humidity environment and reliable work. Electric two-way valve installation and debugging: must read the instructions carefully before installation, cut off the power supply and must be installed by professional and technical personnel. In the direction of flow must be the same with the direction arrow on the valve body. body shall be located above coil water pans, in place to ensure that when a drop of water fell into the water tray. Body and the driver must be installed in vertical direction + 60 ℃ within the scope of the above should be at least 30 mm space for dismantling. With the piping, equipment, buildings have to keep enough space for maintenance operation, must be installed in the maintenance personnel can touch through manhole. installed with line through after pressure can only be installed driver. If the driver has been loaded on the body, so you must not to drive in the process of installation and debugging work, otherwise it will damage the driver. After installation and check the correct, electricity debugging. At least should observe three complete and effective operation of the drive, make sure all components are right. After qualification adjustment of the water, and then to water test. System fluctuation of pressure difference must be strictly controlled in 0. Within 15 mpa, in order to assure the effectiveness of the electric control valves for water flow switch. Electric two-way valve of the scope of application: air conditioning, heating, ventilation, hot water civil system level such as chemical industry, petroleum, metallurgy, electricity, light industry and other industries in the process of automatic control.
