What are the structure and advantages of carbon steel gate valves 30С41НЖ?

carbon steel gate valves 30С41НЖ has the characteristics of small fluid resistance, applicable pressure, large temperature range, etc. It is the most commonly used shut-off valve used to cut off or connect the medium in the pipeline. Diameter shrinking can reduce the size of parts, reduce the required force for opening and closing, and at the same time expand the application range of parts. The fluid resistance loss increases. Low pressure gate valve is commonly used in domestic cast iron materials, cast iron gate valve often occurs frozen body crack, gate off and other serious problems, cast iron valve carbon steel valve stem is easy to rust, packing gasket quality is poor, inside and outside the leak is serious. Our PN10 low-pressure carbon steel gate valve replaces the traditional iron gate valve, which effectively solves the problems of easy freezing and cracking of the cast iron gate valve housing, easy detachment of the gate plate, easy rust of the stem, and unreliable sealing performance.
Carbon steel gate valve
The advantages of carbon steel gate valve are as follows:
1. Light weight: The body is made of high-grade ball black cast iron, which weighs about 20%~30% lighter than traditional gate valves and is easy to install and maintain.
2. Casting the valve body: The valve body adopts precision casting. The precise geometry allows the valve body to seal the valve without any finishing.
3, flat-bottomed seats: the traditional gate valve is often in the water after the tube is washed because foreign objects such as stones, wood, cement, iron, debris, etc. deposited in the bottom of the valve groove, easily caused by the leak can not close and form a leak Phenomenon, the bottom of the elastic seat sealing gate valve adopts the same flat design as that of the water pipe machine, which is not easy to cause debris accumulation and make the fluid unobstructed.
4. Overall encapsulation: The gate uses high-quality rubber for internal and outsourced rubber. The European first-class rubber vulcanization technology enables the vulcanized gate to ensure accurate geometric dimensions, and the rubber and spheroidal cast gates are then firmly secured. Shedding and good elastic memory.
