High security media conditioning for WSVX regulators
2021-04-09 10:02:57
Product features: stainless steel bellows and graphite packing sealing structure, the medium in the pipeline is isolated from the outside; the electric actuator adopts integrated structure design, with self-diagnosis function, convenient to use and adjust.
The WSVX high-temperature heat-conducting oil special three-way electric control valve is developed and designed by Shanghai Wanxun Instrument Co., Ltd. It is specially developed for the use of oil-conducting thermal temperature control system in printing and dyeing, chemical fiber and chemical industries. Based on the advanced product technology of famous foreign companies, the product adopts double sealing structure of stainless steel corrugated pipe and graphite packing, so it can effectively isolate the medium in the pipeline from the outside world, and improve the safety and reliability of product sealing. It is suitable for medium regulation in highly toxic, volatile and easy to penetrate.
By changing the opening degree of the valve and simultaneously feeding the isolation signal of the valve opening degree to the control system, the WSVX type high-temperature heat-conducting oil special three-way electric regulating valve realizes the mediation of the parameters such as pressure, temperature and liquid level. This product is equipped with WL intelligent straight-stroke electric actuator, which is small in size, full in specifications, light in weight, large in thrust, low in noise, no adjustment potentiometer, high reliability and convenient operation. The controller accepts 4~20 mA control signal or switch control signal, the maximum thrust can reach 16000 N, and the return difference is less than +/-1.0%. The WL electric actuator is designed with integrated structure and self-diagnosis function, which is convenient to use and adjust. The electric actuator can realize fault diagnosis, alarm and protection functions of the off-control signal, that is, the actuator can be selected to be turned on, off, and maintained when the signal is broken, or any position preset between 0 and 100% can be selected; The electric actuator also has a function of judging, alarming and protecting the valve with a stall. The device uses the WAP4 intelligent controller with multiple functions to facilitate parameter modification. For example, when the input control signal is faulty, the protection mode for executing its output is selected; when the input control signal is faulty, the actuator outputs the desired set position; the actuator action mode, and the like.
In addition, the electric control valve has the characteristics of high mediation precision and good mediation performance, allowing the temperature difference up to 150 degrees. The valve body and valve seat of the regulating valve body are made of Stellite alloy surfacing (1Cr18Ni9Ti4), and the packing is made of polytetraethylene. Therefore, in addition to the guiding action of the bushing at the bonnet, the side surface of the valve core and the inner surface of the valve seat also have a guiding effect, and the guiding area is increased. The bellows is well sealed and forms a secure seal against the moving stem, thus preventing liquid leakage. â–¡Qiu Liang
