Zzyp / N / M self operated pressure regulating ȤӮ羺APP
summary
Zzyp / N / M type self operated single seat / double seat / sleeve pressure regulating ȤӮ羺APP is composed of ȤӮ羺APP body, ȤӮ羺APP seat, ȤӮ羺APP core, balance spring and other components. It is a ȤӮ羺APP that uses the pressure change of the regulated medium without additional energy. According to the mechanical principle, the controlled medium is introduced into the actuator to generate force to push, and the upper and lower position of the ȤӮ羺APP core element is controlled to achieve automatic adjustment, Energy saving products with constant or reduced pressure before or after the ȤӮ羺APP. The biggest characteristic of the product is that it can work in the place without electricity and gas, and the pressure setting value can be adjusted within a certain range during operation. It is widely used in petroleum, chemical, power plant, light industry, printing and dyeing and other industrial equipment for automatic control of gas, liquid, steam and other media pressure.
There are two types of actuators: diaphragm type and piston type; the action forms are: front pressure regulation (k) type (pressure relief and pressure holding type), and back pressure regulation (b) type (pressure reducing and stabilizing type); the temperature isolation condensing tank is attached, which can be used at the temperature 350 . According to different working conditions, different ȤӮ羺APP core structure and different actuator can be selected to achieve the best control effect.
