Electric control valve is used to drive the electric actuator to drive the valve to throttle the pneumatic control valve, which is an important industrial automation process control unit instrumentation. As the degree of automation in the industrial field is getting higher and higher, it is being used more and more in various industrial fields. Compared with the traditional pressure control valve series has obvious advantages: electric single-seat control valve energy-saving (consumption of electricity only during work), environmental protection (non-carbon emissions), the installation of regulatory control valve series fast and easy (without complicated pneumatic tube Road and air pump work station) Electric control valve Driven differential pressure control valve by receiving signal of industrial automation control system (eg 4 ~ 20mA) Series Door Changing the cross-sectional area between valve core and valve seat Controlling the flow rate and temperature , Pressure and other process parameters. Automatic adjustment function. Temperature control valve series of low-flow resistance through the single seat valve. (Also can be equipped with other brands of straight-line Cheng executive body). Electric sleeve valve electric actuator for the electronic integrated structure, servo amplifier inside, Daejeon Pneumatic membrane control valve input control signal (4-20mADC or 1-5VDC) and the power supply to control the valve opening to achieve the pressure , Flow, level, temperature and other parameters of the regulation. Daejeon electric sleeve regulating valve series with a sensitive, simple connection, flow, small size, high precision adjustment and so on. Control accuracy and performance than the DKZ type has significantly improved. Single-seat electric control valve for leakage on the strict requirements, the valve before and after the low pressure and a certain viscosity of the occasion. Three-way joint control valve is widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries. Note: Normal temperature type: room temperature type operating temperature -20 - +200 ℃, leak level is Ⅳ level. High-temperature bonnet additional heat sink can be used for medium temperature -60- +450 ℃ occasions. Bellows sealed up and down movement of the electric ball valve stem to form a complete seal, blocking fluid leakage. Low-temperature type with extended valve cover and insulation board structure can be -196 ℃ cryogenic occasions.
Vacuum Glass For Passive House
The passive room requires very low building energy consumption (annual heating or cooling demand per unit area ≤ 15kwh-2a-1), and the external windows of the building are required to have excellent daylighting, thermal insulation, thermal insulation and sealing performance. If required, the U value of heat transfer coefficient of external window shall be ≤ 0.8W / (M2·K). Building glass accounts for about 70% of the area of the outer window and plays a major role in the daylighting, thermal insulation and thermal insulation performance of the outer window. Therefore, the passive room has high requirements for window glass. ICESUN vacuum glass has a series of obvious advantages including long lifespan, wide application fields, super sound proof performance and good anti condensation, which makes vacuum glass for passive house widely praised. Besides, ICESUN also can provide high quality Safety Vacuum Glass for other buildings, such as Vacuum Glass For Greenhouse, Vacuum Glass For Sun Room and so on.
