Burkert angle seat valve for nitrogen generators, double-acting type, starting with 931.

Burkert angle seat valves for nitrogen generators, double-acting type 931. The closing principle of the German Burkert pneumatic angle seat valve: Relying on the valve stem pressure, the valve disc sealing surface and the valve seat sealing surface are tightly fitted, preventing media flow.

It can control neutral gases, air, automated industrial control fluids, food-grade dairy industry fluids, domestic water, and ordinary pipeline fluids.

The Burkert 2000 model pneumatic angle seat valve for nitrogen generators is widely used in: food, pharmaceuticals, beer, beverages, bioengineering, water treatment, daily chemicals, printing and dyeing, machinery equipment, nitrogen and oxygen production, automation equipment, petrochemicals, and other fields.

Features of the Burkert pneumatic angle seat valve for nitrogen generators:

• Valve open/closed position indicator.
• External pneumatic pilot, increasing service life and requiring no maintenance.
• Self-adjusting sealing gland between the overflow port and the slider improves sealing performance.
• Valve body angle seat structure, enabling large flow rates (especially compared to ordinary gate valves), compact structure, and fast response. Installation and Function of Burkert Pneumatic Angle Seat Valves for Nitrogen Generators: Installation and maintenance must comply with applicable safety regulations:
• Pipelines must be clean and free of contamination.
• Install as needed, but with the actuator facing upwards. Pay attention to the flow direction.
• When connecting the valve, ensure alignment with the pipeline;
• remove the actuator only if specifically requested by the user.
• Before opening or servicing the angle valve, shut off the fluid and control air supply and reduce the pressure in the pipeline system. Burkert Pneumatic Angle Seat Valves Installation and Maintenance Guidelines:
• Pipelines must be clean and free of contamination.
• Install as needed, but it is best to have the actuator facing upwards. Pay attention to the flow direction.
• When connecting the valve, ensure alignment with the pipeline;
• remove the actuator only if specifically requested by the user.
• Before opening or servicing the angle seat valve, shut off the fluid and control air supply and reduce the pressure in the pipeline system. In terms of service During full closure, the valve disc travels a small distance, resulting in a relatively small height. Burkert angle seat valves for nitrogen generators are double-acting (starting with 931). The automatic reset principle of Burkert pneumatic angle seat valves: A spring is installed at the handle, using a lever-type single-sided spring as the actual principle. When the handle is opened, the spring is compressed;
• When the handle is released, the spring pushes the handle to close. Its function relies on the principle of automatic spring rebound and reset. Its service life can reach millions of cycles. structure, light weight, and low flow resistance.
• Uses industrial plastic or hard sealing materials, providing good sealing performance.
• Simple operation, rapid opening and closing, and long service life.
• When fully open or fully closed, the valve seat seal is isolated from the medium, making it less susceptible to corrosion or friction damage.
• Pneumatic actuator, rationally designed and highly practical. Burkert Nitrogen Generator Angle Seat Valve - Improved Manufacturing Method of Nitrogen Generator Angle Seat Valve Background Technology: During the operation of a nitrogen generator, it is found that the purity and output of the nitrogen generator often drop suddenly. After stopping the machine for inspection, it is found that the cause is that the pressure equalization DN80 angle seat valve of the nitrogen generator is broken at the positioning hole and thread connecting the valve stem and the valve seat. Due to the complex structure of the valve stem and valve core of the angle seat valve, an inner sleeve is fitted inside an outer sleeve. The valve stem is threaded to the inner sleeve, and the outer sleeve is threaded to the valve core. The connection between the valve stem and the threaded inner sleeve is machined with a step, which may lead to localized stress. below the valve core ensure proper alignment. This structure causes shear stress in the valve stem, exacerbating the risk of breakage at weak points. After a period of online operation, this type of angle seat valve will inevitably experience valve stem breakage at the threaded hole. This results in the actuator and valve stem moving, but the valve core not moving in sync with the valve stem, leading to valve malfunction, abnormal pressure equalization, decreased nitrogen generator purity and output, and even substandard nitrogen, affecting the normal operation of the nitrogen generator and posing a safety hazard. Technical Elements: To address the shortcomings of existing technologies, the purpose of this invention is to provide an improved angle seat valve for a nitrogen generator, simplifying the connection structure between the valve stem and valve core, thus preventing valve malfunctions and ensuring the smooth operation of the nitrogen generator. the valve stem, which mates with the inner diameter of one end of the threaded external sleeve;
• the inner diameter of the other end of the threaded external sleeve has internal threads;
• the valve core has external threads, which connect to the internal threads of the inner diameter of the threaded external sleeve;
• a flexible valve seat is embedded within the valve core. Further, a hollow groove is provided inside the valve core on the side away from the threaded external sleeve, and a positioning block is provided within the hollow hollow groove;
• the flexible valve seat is assembled into the hollow groove of the valve core, and the flexible valve seat has a central through hole, which engages with the positioning block for positioning. Furthermore, a pressure cap is provided on the side of the flexible valve seat away from the valve core. the valve stem. The beneficial effects of this invention are: it simplifies the connection structure between the valve stem. and the valve core, strengthens the connection strength between the valve stem and the valve core, avoids valve malfunctions that could cause the nitrogen generator to shut down for maintenance, and ensures the safe and stable operation of the nitrogen generator.
