Analysis of stainless steel filter nozzle

The material of stainless steel filter nozzle: 304, 304L, 316, 316L, 2507, Hastelloy, etc.

02 Composition of stainless steel filter nozzle:

The filter nozzle is composed of a filter nozzle seat, a filter nozzle cover plate, a wedge wire screen pipe with ribs, and a guide pipe.
The middle axis of the wedge wire screen pipe is provided with a flow-through valve cup which is upside down fixed on the filter nozzle seat. The lower opening contains the part where the upper part of the guide pipe extends into the filter nozzle seat. The bottom and wall of the flow-through valve cup and the upper pipe wall of the guide pipe are provided with a plurality of pores, and the top end of the guide pipe is provided with a flow-through valve core that can float up and down.

By setting the flow rate, the number of round holes, the aperture size, and the clearance distance of the wedge wire screen, the filter nozzle can meet the various velocity ratios of the backwashing and filtering water velocity under different process conditions.

03 Type of stainless steel filter nozzle:

  1. According to the classification of the production process, it can be divided into stamping and car parts.

There are four common diameters of the cover plate of the stamping filter nozzle in China, which are 45, 53, 57, and 70 respectively. Generally, the stamping filter nozzle has rivets. Because the length of the rivets is limited, the length of the stamping filter nozzle is also limited. The height of the stamping filter nozzle commonly used in China is 40, 45, 55, and 70.
The conventional gap is 0.25, and the conventional wire diameter is 1.5 * 2 and 1.8 * 2.5. However, there are not so many regulations for the filter nozzle, and the diameter can be customized in various sizes.
Generally speaking, the length of the car part filter nozzle is wider than that of the stamping filter nozzle.

  1. According to the shape, it can be divided into pipe type single head filter nozzle, pipe type double head filter nozzle, pull-type single head filter nozzle, pull-type double head filter nozzle, long handle filter nozzle, deck type single head filter nozzle, double-flow speed filter nozzle, flat filter nozzle, etc.

04 Advantages of stainless steel filter nozzle:

Stainless steel filter nozzle instead of water treatment equipment, traditional plastic filter nozzle, plastic filter nozzle has poor strength, pressure resistance, temperature resistance, anti-aging performance, especially strength weakness, which is vulnerable to rupture, which brings hidden trouble to the safe operation of equipment.

Stainless steel filter nozzle can help users to solve the worries caused by the original plastic filter nozzle.

The product has a large circulation area (about 2-3 times the same size as the plastic slit type filter nozzle). It has the advantages of good aging resistance, good pressure resistance, long service life, no damage, safety and reliability, and low comprehensive cost. It is a new generation of products in the water treatment equipment industry.
Although the unit price of stainless steel wedge wire filter nozzle is higher than that of plastic filter nozzle, its advantages far exceed its value. After replacing the stainless steel filter nozzle, the wear resistance rate is improved and the service life is longer.

05 Application of stainless steel filter nozzle:

Stainless steel filter nozzle is widely used in power plants, petroleum, chemical, pharmaceutical, food, and other industries in the field of water treatment equipment. It is the key component of water distribution and water device in water treatment equipment.
