    The stem of china DIN3352 F4 resilient seated gate valve adopts stem seal structure, and the stem seal adopts three O-rings structure. The third O-ring can reduce the pressure at the gland, and at the same time, it can realize the replacement of the upper two seal rings when the pipeline has medium pressure. Compared with the stuffing box structure, the O-ring sealing structure can effectively reduce the opening and closing torque of the valve.

    The core parts of the Best DIN3352 F4 resilient seated gate valve mainly include valve body, bonnet, stem and gate.The sealing of the whole Best DIN3352 F4 resilient seated gate valve mainly depends on the contact between the rubber gate and the casting. The rubber has a small amount of elastic deformation due to stress to achieve good sealing effect. The sealing is reliable, and can achieve zero leakage. The friction coefficient is very small, the wear is small, the torque of the valve is small when it is opened and closed, the operation is light, the service life is long, no pollution, corrosion resistance and the appearance is beautiful.

    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.
