Four.Product Description:

The stainless steel manhole is a safety emergency ventilation device mounted on top of the storage tank.It is usually used with fireproof and mechanical breathing valve, which can not only avoid accidents caused by sharp overpressure or vacuum in the tank and damage the tank, but also play a role of safe fire retardation. It is a safety device to protect the tank, especially suitable for the vault atmospheric pressure tank whose storage materials are capped with nitrogen.It has the advantages of constant pressure discharge, constant pressure suction, flexible opening and closing, safe fire resistance, compact structure, good sealing performance, safe and reliable, etc.

◇ Food, beer, dairy, chemical container and other industries.The manholes of pressure vessels are also made of quick-opening structure, which is convenient to open, safe and practical and beautiful in appearance.

VI. Product structure:

◇ A sanitary quick opening manhole comprises a cylinder section, a head and a buckle device, the upper end of the cylinder section is welded with a lower flange, and the lower end of the head is welded with an upper flange corresponding to the lower flange.On flange welding are described in the shaft frame, described the flange welding are corresponding with the shaft on frame under the shaft frame, described on the shaft frame toward the axis of the rack is equipped with the corresponding rotating mandrel, as described in the under side of the rotating spindle is equipped with and horizontal direction or at an Angle of screens, described the shaft frame and rotating mandrel through throughout its axis of isometric double-headed stud connection, isometric described the ends of the double end studs through under the cap nut and shaft connection, described between shaft frame under the cap nut and a spring washer;And the cylinder section and the head are fixedly connected by a plurality of circumferential uniform clamping devices.

VII. Product advantages:

1, stainless steel manhole has good environmental protection, no bacteria factors, can be used in dairy products, wine, food, cosmetics, biology and other demanding environment;

2, stainless steel manhole using stainless steel material with high strength, easy processing, superior corrosion resistance, with ultra-high cost performance.

3, stainless steel manhole with quick opening structure, not only open convenient, safe, practical and beautiful appearance, more importantly, can be customized according to the requirements.

4, stainless steel manhole installation is quick and convenient, avoid the construction site complex dangerous wire work, welding work.

5, stainless steel manhole is more superior, in the reasonable use of the service period almost do not need to stainless steel manhole maintenance and maintenance, can be very good to ensure the use effect.

Eight, product use:

◇ Stainless steel manhole is an indispensable part of the storage tank, mainly installed on the top of the storage tank with a safety emergency device, with fire paint, mechanical breathing valve matching use is the most common.Stainless steel manhole is a health manhole attribute, also has a very good application in the brewing industry, such as food, beer, dairy, beverage, chemical containers, biological and pressure vessel industry, are widely used, stainless steel manhole is currently recognized as environmental protection, health, scientific manhole products.
