- Imported power station welding gate valve<
Also known as high-voltage power station gate valve, it is mainly suitable for cutting off or connecting pipes in various systems of thermal power stations. Road medium. Applicable media for high-pressure welded gate valves: water, steam and other non-corrosive media. Compared with other valve products, the characteristics of high-voltage power station gate valves are high temperature and high pressure. Unique self-sealing design. The higher the pressure, the more reliable the sealing. Due to the performance and technical characteristics, the workmanship The special conditions make the product have characteristics that cannot be replaced by other products. High-pressure welded gate valves should generally be installed horizontally in pipelines.<

. The shell adopts two process options: forging and casting. The appearance is smooth and the structure is uniform to meet high temperature and high pressure requirements; a full range of fully forged steel gate valves can be provided according to user needs;<
Special material pairing ensures high hardness and poor hardness of the sealing surface; Precision ground and smooth as a mirror, wear-resistant and corrosion-resistant, effectively extending service life;<
, back seal design effectively protects the sealing packing to prevent leakage;<
, high-pressure water strength, high-pressure gas strength non-destructive testing and other multi-channel testing Comprehensively control the quality of pressure-bearing parts;<
, the surface of the valve stem is precision ground and hardened to resist scratches and corrosion, effectively reducing the opening and closing torque and making operation easier;<
, using a special corrosion-inhibiting filler structure The design is temperature-resistant and pressure-resistant, corrosion-free, and automatic lubrication reduces opening and closing friction to avoid corrosion on the surface of the valve stem, thereby eliminating leakage;<
. The two-way pressure-bearing seal design meets the stringent requirements of various special working conditions;<
, Strict manual grinding to ensure the consistency of the sealing surfaces on both sides<
