Single-seat control valve structural features and the use of single-seat control valve is the case with the regulation of body composition different actuators perform meter industrial site that accepts 4-20mA or pulse signal conditioner output for closed-loop control, realization of flow, pressure, temperature, level and other parameters of automatic control and can choose intelligent electric actuators, digital transmission and DCS, PLC, etc., consisting of more intelligent control systems. Electric control valve supply voltage 220V and 380V two kinds of how much pressure relief valve, the electric control valve flow characteristics, there are three equal percentage, linear, and fast. Electric control valve pneumatic control valve, compared with energy-saving (only consumes power when working), environmental (carbon emissions), quick and easy installation (no complicated pneumatic line and pump station) etc., are widely used in electricity , chemical industry, metallurgy, environmental protection, water treatment, light industry, building materials and other industrial automation systems. Through single-seat control valve Detailed structure through single-seat control valve from the valve, valve seat, valve guide sleeve, bonnet, stem and packing and other parts. Plug and stem together. The method can be used to connect an interference fit or threaded pin fixed pin fixed to be the stem and the valve power station valve core one car out. Between the valve cover and valve body has a guide sleeve valve, the valve moves up and down to play a guiding role. The guide sleeve holes, connecting the body cavity and the valve outlet end. Guide sleeve cavity medium can easily flow into the outlet end of the valve through the hole, it does not affect the movement of the spool. Through single-seat control valve of a spool valve body and a valve seat only. Characterized by a small amount of leakage, easy to guarantee the seal. There are regulated and cut-off the structure. Their difference lies in the shape of the spool. Adjusting the shape of the plunger-shaped spools; shape cut spools of flat or tapered, it's another feature is medium large force on the spool valve parameters, namely unbalanced force, particularly It is more serious in the case of high differential pressure, large diameter, so only for low dropout applications. Otherwise, it should be chosen thrust of the actuator, or with positioner. Valve ex-valve, inline instrumentation Tianchang instrument provided by the United Instrument Sales Co., Ltd.
