The stainless steel wedge wire nozzle is composed of a water cap bottom, a water cap cover, a trapezoidal screen tube with ribs and a guide tube. The central axis of the trapezoidal screen pipe is provided with a flow valve cup which is fixed upside down on the water cap bottom. The upper pipe wall of the pipe is provided with a plurality of holes, and a flow-through valve core that can float up and down is provided on the top of the guide pipe. By setting the flow rate, the number of circular holes, the aperture size and the gap distance of the trapezoidal screen, the wedge wire nozzle can meet various flow rate ratios of backwash and filtered water flow rates under different process conditions.
Material of stainless steel wedge wire nozzle: 904L, 304, 304L, 316, 316L, 2507, Hastelloy, etc.
Types of stainless steel wedge wire nozzle:
1. According to the production process, it can be divided into two types: pressing and car parts.
There are four common diameters of the pressing wedge wire nozzle cover in China, which are 45, 53, 57, and 70. The pressing wedge wire nozzle generally has rivets. Because the length of the rivet is limited, the length of the pressing wedge wire nozzle is also limited. The domestic common heights are 40, 45, 55, 70. The conventional gap is 0.25, and the conventional wire diameter is: 1.5*2, 1.8*2.5, while the wedge wire nozzle for car parts does not have so many regulations, and the diameter can also be customized in various sizes. Generally speaking, car part wedge wire nozzle can be customized in a wider length than pressing wedge wire nozzle.
2. According to the shape, it can be divided into pipe type single head wedge wire nozzle, pipe type double head wedge wire nozzle, wrench type single head wedge wire nozzle, wrench type double head wedge wire nozzle, long handle wedge wire nozzle, deck type single head wedge wire nozzle, double flow rate wedge wire nozzle, flat wedge wire nozzle, etc.
The advantages of stainless steel water caps:
Stainless steel wedge wire nozzle replace traditional plastic wedge wire nozzle in water treatment equipment. Plastic wedge wire nozzle have poor strength, pressure resistance, temperature resistance and aging resistance, especially the weak point of poor strength, which is easy to break, which brings hidden dangers to the safe operation of the equipment. Stainless steel wedge wire nozzle can help users solve the worries caused by the original plastic wedge wire nozzle. This product has a large circulation area (about 2-3 times that of the plastic slit wedge wire nozzle of the same specification), anti-aging, good pressure resistance, long service life, not easy to damage, safe and reliable, and low comprehensive cost. It is new generation products in water treatment equipment. Although the unit price of stainless steel wedge wire nozzle is higher than that of plastic one, its advantages far exceed its value. After replacing the stainless steel wedge wire nozzle, the wear resistance rate is improved and the service life is longer.
Stainless steel wedge wire nozzle are widely used in the field of water treatment equipment in power plants, petroleum, chemical, pharmaceutical, food and other industries, and are key components in water distribution and water devices for water treatment equipment.
