  • Do you understand the requirements and testing knowledge of DIN3352 F4 resilient seated gate valve?

    Do you understand the requirements and testing knowledge of DIN3352 F4 resilient seated gate valve?

    2021-04-06

    The specifications and categories of DIN3352 F4 resilient seated gate valve shall meet the requirements of the pipeline design documents.

    The gate valve is a gate for opening and closing parts. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.

    Resilient seat gate valve is the replacement product of common low pressure cast iron gate valve, known as/green valve 0, and has been used in many countries and regions in the world.

    The principle of plugging under pressure is based on the sealing mechanism of solid sealing materials under dynamic conditions of liquid media. The method is to install special equipment at the leaking part, use the cavity formed between the sealed part and the special equipment, and use a special high-pressure glue injection tool to inject the sealant into the chamber, and fill the entire chamber space to make the sealant squeeze The force is balanced with the pressure of the leaking medium, and a new sealing structure is established to block the channels of the leaking pore and block the leakage of the medium.

    The sealing performance of the resilient seat gate value is better than that of the stop valve, the fluid resistance is small, and it has a certain adjustment performance. The exposed rod type can still adjust the opening and closing degree according to the height of the valve stem. The disadvantage is that the structure is more complicated than the stop valve, the sealing surface is easy to wear, and it is not easy to repair. In addition to suitable for steam, oil and other media, gate valves are also suitable for media containing granular solids and high viscosity, and are suitable for venting valves and valves for low vacuum systems.

    The last thing to remind everyone is that during the installation of the resilient seat gate value, at least two operators must be present at the same time, and they cannot be used immediately after the installation is completed, but an effective trial should be carried out first to ensure the safety valve After it can work normally, put it into use.

    This is mainly because the resilient seat gate value has a small displacement and the safety discharge capacity of the equipment. The appropriate safety valve should be re-selected; the center line of the valve stem is not correct or the spring is rusted, so that the valve disc cannot be opened to the expected height, and the valve stem should be reassembled Or replace the spring; if the exhaust pipe is insufficiently cut, use an exhaust pipe that meets the safe discharge area. 6. Opening below the specified pressure

  • What is the difference between hard seal gate valve and  resilient seat gate value Manufactures

    What is the difference between hard seal gate valve and resilient seat gate value Manufactures

    2020-09-03

    The selection of resilient seat gate value and hard seal gate valves is mainly based on the process medium, temperature and pressure. Generally, the medium contains solid particles or wears or the temperature is higher than 200 degrees. It is best to use hard seals. Valves with a diameter greater than 50 have a larger pressure difference and consider opening the valve torque. , When the torque is large, the fixed hard-seal gate valve should be selected, and its sealing level can reach 6 regardless of the soft or hard seal.
