the control valve of the imported nitrogen sealing device (nitrogen sealing valve) is composed of control valve, actuator, pressure spring, commander, pulse tube and other components. It is mainly used to keep the pressure of the protective gas (generally nitrogen) at the top of the container constant, so as to avoid direct contact between the materials in the container and the air of the deputy factory director, which is expected to be widely used in actual production, so as to prevent the volatilization and oxidation of materials, as well as the safety of the container. It is especially suitable for the gas seal protection system of all kinds of large storage tanks. The product has the characteristics of energy saving, sensitive action, reliable operation, convenient operation and maintenance, etc. It is widely used in petroleum, chemical industry and other industries

the regulating valve, also known as the control valve, changes the fluid flow with the help of power operation by receiving the control signal output by the regulating control unit. The regulating valve is generally composed of actuator and valve. The power used by the actuator can be divided into: pneumatic control valve, electric control valve, hydraulic control valve, self operated control valve; According to the function and characteristics, it can be divided into: linear characteristics, equal percentage characteristics, parabolic characteristics; According to the characteristics of travel, it can be divided into straight travel and angular travel. There are many kinds of valve bodies for regulating valves. The commonly used valve bodies include straight through single seat, straight through double seat, angle, diaphragm, small flow, tee, eccentric rotation, butterfly and sleeve. The regulating valve is applicable to air, water, steam, various corrosive media, mud, oil and other media

working principle of the nitrogen supply device: the medium at the pressure tapping point of the capping is introduced into the detection mechanism through the pressure pipe, and the medium generates a force on the detection element to balance with the preset spring preload. When the pressure in the tank is reduced to less than the pressure set point of the nitrogen supply device, the balance is broken, so that the valve core of the commander is opened, so that the gas in front of the valve enters the upper and lower membrane chambers of the main valve actuator through the pressure reducing valve and throttle valve, and the valve core of the main valve is opened, Fill the tank with nitrogen; When the pressure in the tank rises to the pressure set point of the nitrogen supply device, due to the preset spring force, close the plate formed by hot extrusion, close the valve core of the commander, and close the main valve and stop nitrogen supply due to the action of the spring in the main valve actuator

working principle of ammonia release device: the device adopts internal feedback structure. The medium enters the detection mechanism directly through the valve cover. The medium generates a force on the detection element, and the preload of the preset spring is balanced. When the pressure in the tank rises to the pressure set point of the ammonia release device, the balance is destroyed, causing the valve core to move up, open the valve, and release nitrogen to the outside; When the pressure in the tank drops to the pressure set point of the ammonia relief device, due to the preset spring force, close the valve
