Jacket insulation (explosion-proof fire) breathing valve

Due to the fact that the breathing valve is a ventilation device fixed on the top of the storage tank, it ensures the normal pressure inside the tank, prevents overpressure or vacuum inside the tank, and reduces the loss of liquid evaporation in the tank.

When storing chemical products, some chemical media need to keep the tank and breathing valve warm due to temperature. Especially for breathing valves, due to their direct connection with the atmosphere and fast cooling, improper insulation measures can cause crystallization or polymerization at the mouth of the breathing valve, which can lead to tank collapse or rupture (similar accidents have occurred multiple times in China), especially when storing media such as para xylene acetic acid and polyvinyl chloride.

For example, in the cold northern regions, due to the long duration of low temperatures, since oil is stored, the presence of water vapor can also cause ice to form between the valve disc and sealing line of the breathing valve, as well as in the gaps between the flame arrester bellows. Some tank farms, although equipped with steam tripping heat, have poor effects, forcing them to stop operating, affecting normal production, and causing losses to the national economy

In order to solve the above problems, our factory has specially developed jacket breathing valves and jacket flame retardant breathing valves, filling the gap in China. The product is equipped with a jacket layer on the periphery of the breathing valve body, with a steam interface and a condensate outlet set, and an appropriate temperature adjusted. The steam is integrated into the jacket layer, providing all-round warmth for the valve chamber and flame arrester of the breathing valve. In this way, it can solve the operational safety of chemical storage with special temperature requirements, and also solve the worry of being able to operate oil storage and transportation at any time in cold regions during winter. Its economic and social benefits are significant.

The product has a novel and scientific design, a reasonable and compact structure, and a complete range of types and specifications. The double ring partition has good sealing performance, is easy to inspect, and has the characteristics of safety and reliability. Especially suitable for oil storage and transportation tanks in chemical and synthetic fiber tank areas, as well as in cold regions.

Due to the breathing valve is fixed to the top of the tank ventilation means, in order to ensure the normal state of the pressure inside the tank to prevent the tank overpressure or ultra-high vacuum, so that the tank has suffered damage, and also to reduce volatilization loss of liquid in the tank can play a role in.

And storage of chemicals, some chemical medium due to the temperature dependence, need to tanks and breathing valve warm. Special breathing valve, directly connected with the atmosphere, cooling fast, such as improper precautionary measures in the breathing valve Oral Department crystallization or polymerization, and will result in the tank being sucked deflated or broken (There have been several similar incidents) especially storage media xylene, propyl acetate, polyvinyl chloride.

Another example of the cold northern regions, due to the low temperature for a long time, since the oil is stored, but the moisture relationship also cause breathing valve disc and seal line between the corrugated flame arrester with cracks icing. Although some tank farm capable of hot vapor trip, but to little avail forced to stop working, affecting the normal production losses to the national economy

In order to solve the above problems, I developed a special jacket breathing valve and jacket Fire breathing valve to fill the gap. Products coupled with jacketed the breathing valve body peripheral compartment, set the vapor interface and the condensate outlet, the deployment of the appropriate temperature steam into the jacket layer, and a full range of warm breathing valve valve chamber and the flame arrester. In this way, you can solve the operational safety of the chemicals stored in special temperature

requirements, but also solve the cold winter oil storage and transportation can operate at any time to worry about. Its economic and social benefits are significant.

Novel scientific, reasonable and compact structure, type specifications. Bicyclic compartment sealing performance, and easy to check and have a safe and reliable. Especially suitable for oil storage and transportation tanks of chemicals, chemical fiber tank farm and cold regions.
