Filter part

Abstract

The invention provides a filter part which comprises an upper inner sleeve, a lower inner sleeve and a top inner sleeve, wherein the upper inner sleeve, the lower inner sleeve and the top inner sleeve are in fit with interior of an internal thread stainless steel filter valve; a thread consistent with the internal thread stainless steel filter valve is arranged on the outer layer of the upper inner sleeve; an ejector table is arranged at the center of the top inner sleeve; multiple wedge-shaped grooves are formed in the upper surface of the top inner sleeve and are uniformly distributed; multiple filtering contact handles are arranged on the inner wall of the lower inner sleeve; an adsorption device is arranged on the top ends of the filtering contact handles. The inner sleeves can effectively prevent the inner wall of the stainless steel filter from being corroded and damaged, dirt accumulation and blockage can be avoided, the inner sleeves can be tightly attached to the stainless steel filter, installation is stable, and the filtering and adsorbing effects of the filter can be further enhanced through the filtering contact handles on the lower inner sleeve.

Description

technical field [0001] The invention belongs to the technical field of valve manufacturing equipment, and in particular relates to a filter component. Background technique [0002] The stainless steel filter is composed of a shell, a multi-element filter element, a backwash mechanism, and a differential pressure controller. The upper filter introduces timer settings. When the blowdown time is up, the cleaning is stopped, and the system returns to its original state, ready for the next filtration process. The upper cavity is equipped with multiple filter elements, which makes full use of the filter space and significantly reduces the volume of the filter, and the backwash suction cup is installed in the lower cavity. When working, the turbid liquid enters the lower cavity of the filter through the inlet, and then enters the inner cavity of the filter element through the partition hole. The impurities which are larger than the gap of the filter core are intercepted, and the...

AI Technical Summary

Problems solved by technology

[0003] The interior of the stainless steel filter with internal thread is prone to corrosion and other damages under long-term immersion in the medium. The general anti-corrosion layer on the inner wall is not easy to spray, easy to fall off, and does not have the characteristics of elasticity and vibration resistance.
