Static weight safety valve stainless steel micro pressure

1. Simple and reliable structureAdopting a static weight structure, it mainly consists of basic components such as valve body, valve disc, and heavy hammer, without the need for external power or complex pilot systems. It has outstanding advantages of intrinsic safety, strong anti-interference ability, and easy maintenance.

2. Stable performanceThe weight of the heavy plate remains unchanged, and the opening pressure also remains unchanged. The performance is relatively stable, safer and more reliable than spring type safety valves, and easier to install. Due to the use of a heavy hammer loading method, there is no disadvantage of reduced elasticity after long-term use of the spring, resulting in a long service life and low maintenance costs.

3. Excellent corrosion resistanceThe valve body is made of stainless steel 304, 316L and other materials, which have excellent corrosion resistance and are particularly suitable for media such as steam and corrosive gases. Stainless steel material can maintain an annual corrosion rate of less than 0.01mm in chemical environments with a chloride ion concentration of 200ppm.

4. Excellent sealing performanceThe sealing surfaces of the valve disc and valve seat are precision machined, with stable sealing force, opening and closing pressure difference ≤ 15%, good reseating performance, and effective prevention of medium leakage.

5. Security protection mechanismThe valve is equipped with dust-proof, waterproof, and oil proof devices. All valve components that come into contact with oxygen undergo strict degreasing and oil prohibition measures before assembly. The packing material is polytetrafluoroethylene, which ensures safe and reliable use.

Static weight safety valves belong to forced sealing valves, and pressure must be applied to the valve disc when the valve is closed to force the sealing surface not to leak. When the medium enters the valve chamber from below the valve disc, the resistance that the operating force needs to overcome is the frictional force between the valve stem and packing and the thrust generated by the pressure of the medium. The force required to close the valve is greater than the force required to open it.

When the pressure inside the equipment is within a certain working pressure range, the force exerted by the internal medium on the valve disc is less than the force exerted by the loading mechanism on the valve. The difference between the two constitutes the sealing force between the valve disc and the valve seat, causing the valve disc to tightly press against the valve seat and preventing the medium of the equipment from being discharged. When the pressure inside the equipment exceeds the specified working pressure and reaches the opening pressure of the safety valve, the force of the internal medium acting on the valve disc is greater than the force exerted on it by the loading mechanism. Therefore, the valve disc leaves the valve seat, the safety valve opens, and the medium inside the equipment is discharged through the valve seat.

JA42Y static weight safety valve is widely used in oxygen pipeline networks in industries such as steel, metallurgy, medicine, chemical, petroleum, etc., especially suitable for safety requirements in oxygen pipelines, oxygen plants, steel plants, petrochemical plants, and other occasions. Since its launch on the market, it has been highly trusted by major and medium-sized steel mills, oxygen plants, and petrochemical plants in terms of oxygen pipeline networks.
