Features: Stainless steel bellows and graphite packing seal structure, the pipeline media and the outside world isolated; electric actuators with integrated structural design, with self-diagnostic function, easy to use and adjust. WSVX high-temperature heat-conducting oil for three-way electric valve developed by Shanghai Wan Xun Instrument Co., Ltd. is designed for printing and dyeing, chemical fiber, chemical and other industries in the guide oil temperature control system supporting the use and development of products. Based on the technology of digesting and absorbing the advanced products of well-known foreign companies, the product adopts double sealed structure of stainless steel bellows and graphite packing, so it can effectively isolate the media in the pipeline from the outside and improve the safety and reliability of product sealing. For toxic, volatile and easy to infiltrate and other occasions medium regulation. By changing the valve opening, while the valve opening of the isolation signal back to the control system, WSVX-type HTF dedicated three-way electric valve to achieve the pressure, temperature, liquid level and other parameters of mediation. The product is equipped with WL intelligent straight stroke electric actuator, small size, full specifications, light weight, large thrust, small noise, no adjustment potentiometer, high reliability, easy to operate. Controller accepts 4 ~ 20 mA control signal or switch control signal, the maximum thrust can reach 16000 N, hysteresis less than +/- 1.0%. WL electric actuators using integrated structural design, with self-diagnostic capabilities, easy to use and adjust. The electric actuator can realize fault diagnosis, alarm and protection with break control signal, that is, when the signal is cut off, the actuator can be turned on, off, maintained or any position preset between 0 and 100%; at the same time , Electric actuator also has a valve stall fault diagnosis, alarm and protection functions. The device uses a WAP4 intelligent controller, with a number of features to facilitate the modification of parameters. Such as when the input control signal failure, select the implementation of the protection of its output; when the input control signal failure, the implementing agencies output the desired set location; implementing agencies and so on. In addition, the electric control valve has the advantages of high resolution, good mediation performance, allowing the temperature difference up to 150 degrees. Regulating valve body valve seat and the valve used Secretary Lai Lai alloy surfacing (1Cr18Ni9Ti4), the filler is polytetraethylene. Therefore, in addition to the valve cover bushing with a guide role, the valve side and the inner surface of the valve seat also has the role of guide, guide area increases. Corrugated pipe sealing, the movement of the valve stem to form a safe seal, thereby preventing liquid leakage.
Bench lathe - lathe mounted on a workbench. lathe - machine tool for shaping metal or wood; the workpiece turns about a horizontal axis against a fixed tool.With a bench lathe, you can cut, knurl, drill, or grind material to create a new object. The lathe is designed to hold the block at two points and rotate it, allowing the user to reduce the material to a new shape. A commonly used example of a bench lathe is an apple peeler.
